Title: Telemetry capsule for expectant mother and child - has transmitter divided into functional modules to utilise available space
Inventor: CZERNY HERIBERT ING GRAD
IPC: A61B5/00
Filed: 1979-06-26
Abstract: The condition of an expectant mother and child are continuously monitored by a capsule (1) worn on the mother's abdomen before and during birth. The outputs of sensors (2) for heart sounds, etc., are transmitted over a radio link. To keep the capsule small and thin, the Tx is divided into functional modules which plug into the capsule circuit board and utilise all available space. This arrangement also makes adjustments on the modules easily accessible. The module comprise sockets (3,4) commercial pocket-radio battery (5), pre- and matching-amplifiers (6 to 12,23,24) modulator (13), voltage stabiliser (14), RF circuits (15) and antenna (16).

Title: Time-varying dimmer circuit - has two transistors controlling charge of starter capacitor
Inventor: PECHHOLD EBERHARD DIPL PHYS
IPC: H05B39/08
Filed: 1979-06-28
Abstract: The intensity of illumination of large lamps controlled by a timer function ensures automatic and slow dimming after a preset working period. It also allows for slow rise in illumination intensity after switching on the lamp, the dimming and gradual increase of illumination facilitating the use of a staircase and its switches. The slow rise of lamp current extends service life of projector lamps, while the inclusion of complementary transistors and low-value storage capacitors simplifies time behaviour control. The charge current of starter capacitor (C1) is set by transistors (T1,T2) with the charge circuit comprising diodes (D1,D2) controlled by a switch(S). The bases of transistors are connected to storage capacitors (C2,C3) via resistors (R1,R2). The voltage limiter includes diodes and zeners.

Patent DE-2932372-A1 (DE)
Inventor: SCHREINER HORST PROF DR TECHN
IPC: B30B11/10
Filed: 1979-08-09
Abstract: In the manufacture of molded single layer bodies in an automatic press, the press output is substantially increased by providing, on a circular table, at least two work positions at a predetermined distance from each other. At each work position, a pressing process for pressing the powder and an ejecting process for ejecting the finished molded body take place. Filling devices are arranged between the work positions in such a manner that the filling vessel of each filling device covers a wide angular range of the circular table. Pressing and ejecting take place during standstill of the press table, and the filling of the die takes place during the transport of the press table from the one to the other work position.

Title: Ozoniser voltage supply - saves power by two ozoniser(s) in series shunted by reverse connected diode(s)
Inventor: SCHMIDT WALTER DIPL ING
IPC: C01B13/11
Filed: 1979-11-23

Title: Storage system for radioactive substances - with corrosion resistant ceramic covered modules screened in carrier container
Inventor: FINKBEINER RUDOLF DIPL ING
IPC: G21C19/40
Filed: 1980-02-14
Abstract: A device to store radioactive substances, esp. spent nuclear fuel elements, houses the elements in individual metal (steel) cans, surrounded by a ceramic corrosion-resistant shell of carbon and/or silicon carbide and/or alumina.

Title: Numerical controller for multiple axis process machine movements - uses position control unit ready signal to control sequencing
Inventor: KELLER JOCHEN DIPL ING
IPC: G05B19/414
Filed: 1980-06-26
Abstract: A numerical controller enabling accurate movement of a part of a process machine has a demand value generator producing axial increments for a discontinuous multiple axis position control operating in real time. A sequential controller enables compensation of the time delay between calling up the first and other axes without using computer capacity for correction purposes. Generator address and ready signals pass between sequential controller and demand generator. Axis calling and ready signals pass between the sequential controller and the position controller. The calling channels drive an OR gate and via it the axis address device so that the generator call signal is triggered at desined times. The generator ready signal activates the first call signal. Subsequent calls are triggered by position controller ready signals.
