Title: Magnetometer with direct digital coding of test signal - counts pulses of hf generator and converts counter reading by d=a converter into current applied to probe
Inventor: TRENKLER GERHARD PROF DR
IPC: G01R33/04
Filed: 1978-05-27
Abstract: The magnetometer measures magnetic fields are field gradients. It has a probe whose one winding generates an auxiliary field which saturates the core magnetisation loop. The other winding delivers a test voltage depending on the flux density in the core. The auxiliary field is generated by a current produced by counting pulses of an h.f. generator by a digital counter whose reading is converted by a D-A convertor. The counter instantaneous reading is transferred to a store register when the measurement winding voltage reaches an extreme value. The digital value in the store register is the measure for the field intensity and direction.

Title: Vehicle IC engine driven pump - is operated by leverage with movable pivot for varying output inversely to pressure
Inventor: KULKE GUENTER
IPC: F02B63/06
Filed: 1978-10-31
Abstract: The hydraulic vehicle brake system pump (9) is actuated by an engine-driven cam (3) acting on one end of a two-armed lever (6) whose other end bears against the spring-loaded (4) pump plunger (8). This lever has a movable pivot (29) mounted on the cylinder (23) of a piston (24) cylinder unit parallel to the lever. A drill through piston bore (25) is connected to pump discharge so that pump pressure can move the cylinder against a spring (27). When that pressure reaches working level this locates the pivot so that plunger travel does not involve the effective part (14) of the cylinder. Thus the delivery quantity of the pump is automatically controlled within a range from zero to max. in dependence on delivery pressure.
