Museums around the world you may not have heard of: Automobile Museum of China<\/strong><\/p>\n World’s First Drive-Through Museum Coming to China<\/p>\n <\/a><\/p>\n Visitors to an AutomobileMuseum planned for Nanjing will drive their cars into the building and up an undulating, uneven ramp to the roof. As designed by 3Gatti.com Architecture Studio, which has offices in Shanghai and Rome, the 15,000-square-meter museum will offer a drive-through experience, as well as exhibitions, restaurants, shops, a special events space, an automobile sales office, a design center, and laboratories to be visited on foot.<\/p>\n “We designed a building geared to the automobile, where the car is the point of reference,” says Francesco Gatti, the principal of 3Gatti. Gatti’s design is “dedicated to the car as an object of desire, a world to explore, a technology to study and an article to display,” explains the architect. He imagines “a dynamic building with surfaces that are continuous and fluid, without interruptions,” so it recalls the sensation of moving along a road, explains Gatti.<\/p>\n 3.

Patently Obvious: The Lotus 25<\/b><\/p>\n Introduction<\/b><\/p>\n A&R articles are derived from many sources of inspiration. Primarily these are: –<\/p>\n On this occasion the editor was researching the Type 25 and became aware that Colin Chapman was able to secure a patent on his monocoque design. This posed interesting questions and begged further analysis .As a result the editors have sought to provide an interpretation of the design and the context surrounding its design along with an estimation of its success.<\/span><\/p>\n In our study\/ comparison of Chapman and Bugatti [see A&R article] it was explained that Bugatti held numerous patents we can now proceed to explain those taken by Chapman.<\/p>\n Design and patents form the basis of invention ,engineering, wealth creation, sustainability [through the elimination waste \/ duplication\/ inefficiency] welfare and social justice. Therefore it is particularly appropriate that it be discussed in the Chapman and wider context for our subscribers and users of the proposed CCM&EC who may become involved directly<\/span><\/p>\n The editors believe it important that original sources be consulted wherever possible. Furthermore the investigation of the Patent Office\/IPO has revealed further Chapman and Lotus patents. These have considerable implications and will be the source of a forthcoming article.<\/p>\n <\/b>Chapman \/Lotus Benchmarks<\/b><\/p>\n Our subscribers will have opinions on this but in the editors estimation the following are ground braking and in most cases both commercially and competition successful.<\/p>\n Nye observes:-<\/span><\/p>\n \u201cThe twenty-fifth Lotus model had a more profound and far reaching effect upon the development of Grand Prix chassis design than any other single model in history\u201d<\/i><\/b><\/p>\n The Fixed Parameters<\/b><\/p>\n These were the elements that Chapman was unable to alter significantly: –<\/p>\n \u00a0Chapman is likely to have deducted that: –<\/p>\n \u00a0It was said of Chapman: –<\/p>\n \u201cColin Chapman was one of the few who fully appreciated the importance of chassis layout and rigidity, suspension design, overall weight and aerodynamic efficiency\u201d<\/p>\n I.e. the interactive integrated structured package package.<\/p>\n Chapman was likely to have decided what was required combined \u201ccommon sense and scientific design\u201d<\/p>\n \u00a0Factors of Production and Resources \/ Momentum<\/b><\/p>\n What Chapman possessed and formed his considerable resources were: –<\/p>\n \u00a0<\/b>The Team Chapman Assembled<\/b><\/p>\n Those included are believed to be: –<\/p>\n \u00a0<\/b>Past Precedent<\/b><\/p>\n The monocoque was not original.<\/p>\n The better reference works [see below] give historical details and applications. They include:\u00a0 –<\/p>\n \u00a0These may be grasped with reference to editor\u2019s photographs:<\/p>\n \u00a0Shell Shocked<\/b><\/p>\n Conventional wisdom suggests and inference is that Colin Chapman devised the monocoque chassis possibly in a flash of inspiration. The editors doubt this and do not believe it to be consistent with the Chapman methodology. The inspiration theory seems to ignore the scientific analysis of which Chapman was capable and indeed him not using very recent experience or his strategic deductions relating to the opposition and what could be extracted from the opportunity.<\/p>\n The editors believe that the type 25 was really an extraordinary synthesis by Chapman. He was able to feed into the equation the fixed parameters outlined Additionally his own products were an in-house resource. Its very probable that there were ongoing discussion and bouncing of ideas and that the monocoque germinated and was eventually conceived as an integrated totality and holistically by Chapman. However we ought note that the late Ron Hickman suggested an occasion when John Standen drawing experience from the backbone chassis of the Elan suggested that it might form the basis; which in deed it did.<\/p>\n \u00a0<\/b>The term monococque can be slightly confusing and the editors suggest the following might be complementary for the purpose of mental imaging: –<\/p>\n Bamsey observes: –<\/p>\n \u201cChapman had noted that the Coventry Climax V8 engine designed specifically for the new formula was capable of accepting chassis loads and he incorporated it and its fuel tanks into his new \u2013style fuselage. Although called a monococque. This structure did not consist of an aircraft \u2013style single shell. Instead Chapman set two torsion boxes either side of the power train and the driver, these boxes wide and deep enough to form rigid flanks for the fuselage while providing the required fuel accommodation. Bulkheads and the engine tied the two boxes firmly together while the engine and driver squeezed between them, the narrow cockpit closed by g.r.p. shroud\u201d\u201d<\/p>\n Nye provides an excellent comprehendible description of the chassis concept: –<\/p>\n \u201cThe Lotus 25 \u201cbath-tub\u201d chassis structure was effectively two monococque booms linked by an under tray, a bulkhead between cockpit and engine bay, a dash-panel frame and forward bulkhead which provided font suspension mounts and included a hefty cross beam to tie the bottom wishbone mounts across the car\u201d<\/p>\n He continues: –<\/p>\n \u201cThe Lotus monococque finally scaled a mere 65lbs bare, yet offered 1,000 lbs ft\/degree stiffness, rising to 2,400 lb ft\/degree when the Climax V8 was installed in the rear bay\u2026\u2026\u2026The rear horns of the pontoons provided mounts to which the V8 engine was rigidly bolted contributing to chassis stiffness\u2026\u201d<\/p>\n The Type 25 essentially comprised the following: –<\/p>\n It\u2019s reputed that the Type 25 took in the region of 200 man-hours to build.<\/p>\n The Type 25 is made more comprehendible by the technical drawings of James Allington.<\/p>\n Note some of these best drawings are published in Lotus 24,25,28,29, 33 by Unique [which its believed were taken from \u201cAutocar\u201d]<\/p>\n Chapman is often quoted as saying \u201cIt designed it self\u201d the Type 25 might be one of his best examples where design actually dictates it self from the definitions of constraints and opportunities. The Chapman methodology was to not to be handicapped or constrained by conventional restrictions \/ limitations \/regulation or received wisdoms<\/p>\n The monocoque structure was to determine the chassis in motor racing to he present day.<\/p>\n Patents<\/b><\/p>\n To fully comprehend the significance, commercial and competition advantage of a patent the following extracts are extremely useful: –<\/p>\n The Intellectual Property Office [Patents Office] defines a patent as: –<\/p>\n \u201cA patent protects new inventions and covers how things work, what they do, how they do it, what they are made of and how they are made. If a patent application is granted, it gives the owner the ability to take a legal action under civil law to try to stop others from making, using, importing or selling the invention without permission. This may involve suing the alleged infringer through the courts, which is costly and time consuming because it involves expert legal advice. The patent owner needs to be able to pay for this civil legal action and advice themselves, although they may get some costs back if they win their case.\u201d<\/p>\n Further advantages and uses are provided by Pipers Patent Attorneys: –<\/p>\n \u201cThe reasons for filing a patent application are as varied as are the reasons for the existence of the vast numbers of industries, businesses and products that populate our daily lives \u2013 but the main reason that dominates an applicant\u2019s decision to file a patent (or any Industrial Property for that matter) is to maintain an advantage gained through brilliant innovation, small hard-earned incremental advances or even through good luck. \u2028\u2028Filing a patent application is all about maintaining and exploiting a market or a technological advantage. A patent allows its owner a legal means to prevent would be a competitor from gaining a foothold into a particular area of commercial endeavour that would not otherwise be possible. Patents can be used positively as a means to capture an area that needs to be developed, or they can be used negatively as a deterrent to unauthorised copiers. Either way they are a formidable commercial tool. Patents provide the platform for making important commercial decisions \u2013 they are all about how best to use limited capital resources for greatest impact. It has been said that Patents allow innovators to gain vital bridgeheads into technical areas, which can be exploited to:<\/p>\n Consolidate a Strong market position.<\/p>\n Provide new Revenue streams through the licensing or sale.<\/p>\n Gain investment funds to develop and market new products.<\/p>\n Increase in negotiating power through cross licenses or Joint Venture agreements.<\/p>\n Provide the basis for a company culture based on innovation, brand presence and design.<\/p>\n Provide a positive image to potential investors, customers, manufacturers and distributors<\/p>\n Attract and retain key personnel enabling new products to be developed further and<\/p>\n Secure overseas markets, distributors and alliances. \u2028\u201d<\/p>\n Secret Success<\/b><\/p>\n We are reliably told that the Type 25 was designed and built with considerable secrecy at the Cheshunt factory. [This not unusual in such a high technology sport and continues to the present day. All major FI teams are concerned about security and Industrial espionage] Chapman application for a patent and its date is informative. Conventional wisdom suggests that Chapman had some reservations about the performance of the monocoque.<\/p>\n The editors believe that Chapman\u2019s application for a patent was founded on some certainty of the success and that obtaining the patent [see separate paragraph] was to secure the commercial and competition exclusivity on his design. The editors consider that once built and stress tested Chapman knowing the weight and rigidity would have been well aware of the potential. His great unknown might have been the performance under racing conditions. [Aeronautical practice had its advantages but the Comet had demonstrated there could be unanticipated structural issues].<\/p>\n As a supreme strategist Chapman would have been aware the margin between the competitions was small and that his chassis design may have been the greatest variable guaranteeing success.<\/p>\n There might not have been time for extensive testing and this could have given the competition insights in advance and robbed his significant advantage.<\/p>\n In addition although the staff may have been sworn to secrecy there always remains a fear that secrets leak out. Again realizing the successful determining factor of the chassis Chapman may have felt he patent was a means to safeguard a preeminence that might last for several years. This success might guarantee that others were required to pay for the knowledge or product if they wished to remain competitive \/ compete. Otherwise racing rewards would be compensation.<\/p>\n Patent Reference<\/b><\/p>\n A copy of the Patent Specification and associated drawing for the Type 25 is published in Nye \u201cThe Autocourse History of the Grand Prix Car 1966-91\u201d<\/p>\n The details are:<\/p>\n Reference No: L021561<\/p>\n Date of filing complete specification: September 6,1963<\/p>\n Application Date: June 6, 1962 No 21977\/62<\/p>\n Complete specification published March 2 1966<\/p>\n Additionally the facts can be confirmed by reference to the Internet at the Intellectual Property Office.<\/p>\n Obtain information access by: –<\/p>\n References are:<\/p>\n Page Bookmark\u201dGB1021561 [A]-vehicles<\/p>\n Abstract of: GB1021561<\/p>\n No.: 21977\/62<\/p>\n Bibliographic data: GB1021561 [A] -1966-03-02<\/p>\n International Grand Prix Competition 1963<\/b><\/p>\n The following machines and drivers were contracted for the 1963 season: –<\/p>\n\n
\n I am the author of The Leslie Ballamy Story. Regarding your reference\u00a0to the special LMB 15″ wheels. The rear axle ratio needs to be higher,\u00a0not lower, to compensate for the reduced radius of the LMB wheels.\u00a0Typically, a 4.7\/1 or a 4.4\/1 crown wheel and pinion would be used. My\u00a0own 1172 special has LMB wheels and runs a 4.7\/1 crown wheel and\u00a0pinion.<\/em>
