Title: Start and slow running air intake regulator - has regulator dependent servo to open throttle in indirect fuel injection engine
Inventor: THIES KLAUS-PETER DIPL ING
IPC: F02M69/32
Filed: 1975-12-20
Abstract: The slow running regulator (3) for an indirect fuel injector system is subjected to the regulating pressure from the warm up running control (1). The slow running regulator consists of a housing (5) divided into two chambers by a diaphragm (4). The one side (9) of the diaphragm is subject to the regulating pressure and the second side is subject to a return spring pressure (11). The diaphragm is linked mechanically via an adjuster set screw (14) to the throttle valve (5). The fuel injection regulator pressure is low during cold start and warming up phases and the product of regulator pressure multiplied by the diaphragm surface on one side and the spring force on the second side causes the throttle valve to open independent of the accelerator pedal position to admit extra air.

Title: Induction-type thickness gauge for sheet and foil - has probe head on each side of moving workpiece, one with a temp. sensing element e.g. a thermistor
Inventor: URMENYI LASZLE DIPL ING
IPC: G01B7/06
Filed: 1976-09-07
Abstract: The foil and sheet thickness measuring device provides continuous measurement of a moving workpiece. The gauge consists of two probe heads, one each side of the moving sheet or foil (1). One of the heads has a small cut-out in which is placed a temp. sensing element such as a thermistor. The space is also ventilated by an air line. This draws air away from the area in the immediate vicinity of the foil. The output of the sensor (8) is a function of the foil temp. Current induced in a pick-up coil (7) from oscillations produced in an induction coil (6) is a function of the foil thickness. This current is amplified (14) and rectified (15) and a multiplier (16) compensates for the variations of temp. The multiplier output is connected to a comparator (18) to which a reference signal is applied (19). An indicator (20) shows the variation of thickness from a nominal value.

Title: Compact electromagnetic shutter drive - deploys opposingly-moving blades across aperture with pin and slot coupling to solenoid
Inventor: KONDO TOSHIHIRO
IPC: G03B9/10
Filed: 1977-04-07
Abstract: The compact electromagnetic shutter drive has two opposingly moving, reciprocating shutter blades (2, 3) which move over each other to close the aperture.
