Title: Overload safeguard system for press - has pressure cushion in hydraulic fluid circuit reacting on counter-pressure system
Inventor: WEBER HEINZ
IPC: B30B15/28
Filed: 1978-01-10

Title: Electrical transducer for dynamic physical parameter measurement - uses wear-free rolling contact between relatively moving resistance paths
Inventor: DRESEL VOLKER
IPC: G01D5/16
Filed: 1978-07-05
Abstract: An electrical transducer is used for measuring different dynamic-physical parameters. It uses the distance measurement method and is suitable for mass production. Only a very small amount of wear takes place, and consequently, the transducer has a long operating life. The transducer is suitable for use with analogue or digital circuits, does not require additional amplifiers, as used with crystal, strain gauge, and inductive measurement methods, and uses a simple parallel resistance path connection to double the current strength. Sensing is achieved via a wear-free connection between a curved path and a straight or second curved path. The relative motion between the two is a rolling motion.

Title: Modular electric switch with snap-action moving contact - has tilting element, receiving one moving contact end, rotatably mounted in switch housing
Inventor: SCHERZER WOLFGANG ING GRAD
IPC: H01H19/24
Filed: 1978-07-27
Abstract: The switch has terminals in its housing, one serving as the stationary contact. The moving contact is semicircular and can be moved in a snap-action by an actuator between two limit positions. Its one end abuts an edge bearing of tilting element (11), held rotatably in the switch housing (1). The titling element cooperates with a follower (22) of the actuator (18) which has a central recess with a progressive radial extension. Thus a follower of the actuator shaft has a limited play in the recess, in order to attain a free snap-action movement after its dead point has been exceeded, without regard to the position of the actuating shaft.

Title: Combined safety and release valve - esp. for steam circuits in nuclear power stations, has steam ejector on pressure space of piston valve
Inventor: MEIER HERBERT DIPL ING
IPC: F16K31/40
Filed: 1978-09-18
Abstract: A combined safety and release valve, esp. for steam circuits in nuclear power stations, includes a steam ejector on the pressure space of the piston-type valve. The space between inlet nozzle and outlet nozzle of the ejector communicates with the pressure space. The ejector outflow is divided by a solenoid valve from an expansion chamber. Apart from its function as a safety valve in case of excessive pressure, this can act as a release valve to operate at pressure as low as 1 bar. Excessive pressures cannot cause damage because of the built-in damping features.

Title: Double constant-voltage source for optical transmitter - is provided by two Zener diodes and two complementary transistors
Inventor: PESCHKE PETER
IPC: H05B44/00
Filed: 1978-12-14
Abstract: The double constant-voltage source has a first transistor in series between a second Zener diode and its emitter resistor. A first Zener diode is connected to the base. A second transistor complementary to the first has an emitter resistor and is connected by its collector to the first Zener diode and to the first transistor's base and by its own base to the first transistor's collector. The result is two constant-voltage sources that aid one another in their stabilising effect. The prestablised collector branch acts as constant current source for the Zener diode at its collector provided that the sum of the Zener voltages is less than the supply voltage.

Title: Tweeter with exponential horn - coupled to pressure chamber driven by domed diaphragm covered by drilled cap for two mode coupling
Inventor: EHMANN OTTO
IPC: H04R1/30
Filed: 1979-04-21
Abstract: The short exponential horn of a tweeter has a throat diam. of 22mm and is driven by a 'skull cap' diaphragm attached to a speech coil suspended in a ring magnet gap. A domed disc, 16.5mm diam., with the same contour as the skull cap, is held by 4 webs at a spacing of 0.3mm above it. This forms a pressure chamber, coupled to the horn by the annular gap between it and the disc. Further coupling, along the axis of the horn, is provided by a 3.5mm hole drilled in the centre of the disc. The gives a frequency response flat within 2dB from 2kHz to 20kHz. The l.f. response is improved by drilling the magnet pole piece to couple the back of the diaphragm to an air space containing a sound absorber.
