Title: Small electromotor stator including thin-walled tube - covers pole gaps and brushes and collector sealed from fluid around rotor
Inventor: WRASE ARNOLD
IPC: H02K5/14
Filed: 1974-05-09
Abstract: The small electromotor stator has permanently magnetic poles and a thin-walled tube obscuring its pole gaps from the rotor. The stator space enclosing the collector (8) and carbon brushes is sealed from the fluid in the space around the rotor.

Inventor: YOUNG IVAN
IPC: H04L1/24
Filed: 1974-07-20
Abstract: The pulse train is generated by a device for pseudorandom binary sequence generation, which when connected to a clock pulse generator delivers a binary sequence containing only one block with a maximum number of consecutive binary values of a first logic level.

Title: IC engine fuel mixture correction system - uses current from exhaust probe to regulate gas supply to inlet
Inventor: GELE PIERRE
IPC: F02M23/00
Filed: 1975-09-11
Abstract: The system corrects the metering of the fuel/air mixture having one or more gas intake connected to the inlet manifold downstream of the throttle determining the air quantity. A valve regulates the gas supply, and is controlled by the vacuum in a venturi upstream of the throttle via a canister whose diaphragm, subjected to the action of a return spring, is affected by the vacuum as modulated by an electrically-operated valve. The opening of the latter valve is controlled by a probe in the exhaust manifold, supplying a current varying with the composition of the exhaust gases. This current is used in an electronic circuit regulating operation of the valve.
