Title: Improvements in automobile body building systems
Inventor: PIGOTT NORMAN BRIAN
IPC: B62D27/02
Filed: 1986-06-24
Abstract: In a method of building an automobile body separate upper and lower body modules (50, 78) are formed, incorporating the roof area and the floor area of the automobile respectively, precision mating locations (62) on the body modules are used first as reference for fitting interior parts and equipment to the respective modules and then for fitting the modules together. An assembly line for carrying out the method has respective sets of stations for forming operations on upper and lower body modules, a mating station (30) at which the two modules are brought together and a joining station (32) where they are, for example, welded. The leading station (20, 22) in each set determines a master body point (64, 82) on a module presented to it, and forms the mating locations (62) on the module with reference to the master body point.

Title: Signal transforming device
Inventor: LUTTREL STEPHEN PIERS
IPC: G06F17/14
Filed: 1987-03-26
Abstract: The signal transforming device 10 is suitable, inter alia, for producing a Fourier transform. A clock- activated counter 16 selects a cosine function and a sine function value at each of a set of frequencies. The function values are stored in a counter-addressed memory 22. Each value is multiplied in a respective multiplier 20R,20I by a signal sample from buffer 12. The products are added to the contents of respective registers 30R and 30I, in which products involving each function are added to the contents of a respective location. A further signal sample is multiplied by a further value of each of the functions and augments register contents. The register contents are constrained to decay by the application of a decrement factor implemented by memories 28R and 28I. The result is that the invention simulates a bank of filters each with bandwidth governed by the decrement factor and centre frequency set by the corresponding stored function. The invention may be arranged for individual filter centre frequency agility and/or individual filter bandwidth agility. It generalises to arbitrary filters or functions, and provides an elegantly simple means for decomposing a signal into a set of functions and corresponding amplitude coefficients. <IMAGE>

Title: Ignition timing control system
Inventor: MIYAMA SHUJI
IPC: F02P5/152
Filed: 1990-05-16
Abstract: The system has a memory storing a plurality of basic ignition timing values and also storing a plurality of maximum advance values each of which is a maximum timing for producing maximum torque with low-octane gasoline without causing knock.
