Patent DE-2631783-A1 (DE)
Title: Analysing traps in semiconductors - uses double correlation with two different charging pulses for capacitance measurement
Inventor: SCHULZ MAX DR
IPC: G01R31/26
Filed: 1976-07-15
Abstract: The analysis method for investigating traps in semiconductor materials is suitable for semiconductors having deposited Schottky contacts as well as those having internal p-n junctions. Double correlation is used in which two successive pulses of different shape within a defined time slot are correlated together. The traps in the material are charged in two separate areas by the two pulses so that two different relaxation signals may be measured. The time-depenedent capacitance variation resulating from emission of charge-carriers out of the traps into a space-charge zone is thus measured and multiplied and integrated with a reference function. Correlation can be done using a 4-channel correlator and word generator or with a 4-channel box-car integrator.

Title: Flowmeter for fluid or gaseous media - has circulating ball driven by whirling nozzle in annular channel
Inventor: KLEIN HARTMUT
IPC: G01P13/00
Filed: 1976-07-28
Abstract: The flowmeter for fluid and gaseous media consists of an inlet pipe (1) which passes into the inner chamber of a coaxial cylindrical housing to which is connected an outlet pipe (4). The inner end of the inlet pipe is sealed off but it has a number of radial slits (2) forming a whirling nozzle. In the inner chamber is a ball (5) which rolls around the chamber under the action of the vortex produced by the inlet nozzle at a speed which is proportional to the rate of flow through the device. With suitable choice of materials for the ball, its action can be made virtually frictionless. Its motion is detected by an inductive, photo-electric, radiation or other pick-up placed on the outside of the circulating chamber.

Title: High pressure quick closure valve - is on work unit side and affected by stronger spring than pump-side valve
Inventor: LOECKMANN HANS WERNER DIPL ING
IPC: F16L37/36
Filed: 1977-07-22
Abstract: High pressure quick closure coupling comprises two basic parts, a coupling muff and an insert nipple, the one part being connected to a hydraulic high pressure work unit and the other to an oil pump. In each part is a spring-loaded valve which cuts off their outflow apertures when in the uncoupled state. When coupled, they thrust against each other and exert counter influences. The unit-side valve (1) is activated by a stronger spring (2) than the pump side valve (3) spring (4) so that after coupling the pump-side valve (3) is opened and remains so, whilst the unit-side valve (1) remains closed, and can only be opened where a higher opening pressure than that for closing is exerted upon it. An unloading device (6-8) is provided which can be used to open the unit-side valve (1).
