Title: Digital noise generator generates random equiprobable bits - by adding outputs from non-equiprobable generator and binary-series generator
IPC: H03K3/84
Filed: 1973-07-31
Abstract: The digital noise generator generates random equiprobable bits using two generators.

Title: IC engine fuel supply system - exhaust heated rich fuel-air mixture is added to large air flow
IPC: F02M31/04
Filed: 1973-09-24
Abstract: The method involves producing and air/fuel mixture very rich in fuel and in re-heating it by using the heat of at least part of the exhaust gases so as optimum vaporisation of the mixture's fuel is achieved. This heated mixture is then introduced in a volume of fresh air which is larger than mixture's volume, immediately before injection into the cylinder. The ratio between fresh air and rich mixture valves may be varied according to the engines operating conditions. The ratio is typically of the order of ten. The heating is effected using adjacent pipes carrying the inlet mixture and exhaust gas.

Title: Rotational speed reduction gear - uses series of eccentrically driven gear wheels engaged in ring gears
IPC: F16H1/32
Filed: 1974-01-04
Abstract: The high speed input shaft (14) carries an eccentric (19) which fits in an opening (21) in a gear wheel (13a). This wheel has external teeth (15) and an extension (17) which engages in a slot (18) in the casing (1). The gear (15) is positioned within another gear (14a) with internal teeth (16). The eccentric drive and the extension mean that the gear (13a) moves within the other with the teeth (15, 16) engaged over a short distance, causing the gear (14a) to rotate at a reduced speed with respect to the input. The rear face of the gear (14a) carries an eccentric which drives a similar pair of gears. Several pairs can be used, resulting in significant reduction gear ratios.
