Title: Cap nut with internal locking arrangement - has ball between inside face and splayed end of screw
IPC: F16B39/284
Filed: 1975-05-09
Abstract: A locking cap nut (6) used for a permanent fixing, also maintains a well defined clearance between the bearing faces of the screw (3) and nut. The same system may also apply to a blind tapped hole in a component. Beyond the threaded portion the bore expands towards the blinded end, forming a conical cavity (7). The end of the screw is slotted, to form a numer of castellations (5). On assembly, a ball, slightly smaller in diameter than the smallest diameter of the bore of the nut, is placed on these castellations or in the nut cavity. When the screw is tightened, the ball splays out the castellations, thus retaining the nut at that particular spacing from the screw head. Instead of a ball, a conical or half spherical protrusion can be formed at the base of the nut cavity.
Patent FR-2314369-A1 (FR)
Title: Vehicle engine fuel economiser - consists of vessel with air cushion to stabilise fuel pressure positioned between pump and carburettor
IPC: F02M37/00
Filed: 1975-06-12
Abstract: Fuel is drawn from a reservoir by a pump and delivered into the base of a vessel which contains an air cushion above the fuel. The vessel is closed so that air in it is compressed as the fuel level rises. Fuel flows from the base of the vessel to the carburettor. Periodic variation in the pump delivery results in variation in the volume in the vessel so that the pressure of the air compressed in it varies. The compressibility of the air tends to even out the flow fluctuations and maintain an even flow to the carburettor. A pressure relief valve in the side of the vessel allows excess fuel to flow back to the reservoir.
Patent FR-2317814-A1 (FR)
Title: A:D converter with comparator - compares integrated pulses with input and alters pulse frequency to reduce error signal
Inventor: DOMENJOUD JEAN-FRANCOIS
IPC: H03M1/00
Filed: 1975-07-09
Abstract: The A/D converter consists of a pulse generator of variable frequency, an integrator integrating the generator output to give a DC signal whose amplitude is proportional to the generator frequency, and a comparator. The comparator compares the analog input signal with the DC signal to produce an error signal. This signal is used to alter the frequency of the generator so that the difference between the analog input and the DC signal tends to zero. The analog input signal is therefore represented by the frequency of the generator's pulses which are or fixed duration.
