Title: Barrier layer capacitor prodn. - using sintering and reduction of capacitor body, intended for two capacitors, and with two outer long grooves and single central groove
IPC: H01G4/12
Filed: 1980-01-19
Abstract: The capacitor consists of a central, conductive reduction layer, surrounded by a re-oxidation layer. The reduction layer appearing on a surface of a ceramic capacitor body and being contacted with a metal film, without forming a barrier layer. The capacitor body for two barrier layer capacitors is pressed with two, outer, long grooves and a central long groove.

Title: Speed adjuster for clocks with mechanical driving assembly - has quartz-controlled clock switching circuit connected to electro-mechanical transducer supplying release pulses of escapement
Inventor: LEITER ALFRED
IPC: G04C13/10
Filed: 1980-03-08
Abstract: The speed regulator - esp. for technical and large clocks - achieves the accuracy of quartz clockwork without sacrificing the specific advantages of mechanical clockwork. The self-contained assembly is for a mechanical driving assembly. It has an escapement affecting an escapement wheel.

Title: Exhaust gas heat recovery system for drying plant - uses controlled flow through heat exchanger responsive to exhaust gas temp.
IPC: F28D21/00
Filed: 1980-04-05
Abstract: The exhaust gas heat recovery system uses a heat exchanger (2) in the exhaust gas line (1) which uses the exhaust gases as the primary flow medium and which has a secondary flow medium controlled by a flow valve (7). The latter is controlled by a temp. sensor (9) inserted in the exhaust gas line (1). Alternatively the flow of the exhaust gases through the heat exchanger may be adjusted in accordance with the output of a temp. sensor in the secondary flow line. Pref. the secondary flow medium comprises air or water with the heat exchanger coupled to a heating system via mixer valves controlled by the output of a temp. sensor in the primary or secondary circuit of the heat exchanger. The device can be used for the hot exhaust gases from a drying plant which incorporate dust particles and hence cannot be used directly to provide heat.

Title: Control circuit for phase controlled oscillator - with pull-in range increased by positive and negative feedback with diode switching
Inventor: FRITZE BERND DIPL ING
IPC: H03L7/107
Filed: 1980-04-18
Abstract: The range of this control loop circuit for a phase controlled oscillator is increased by employing a combination of positive and negative feedback to an amplifier which produces a sawtooth waveform output for tuning the oscillator until it locks to a predetermined frequency. This circuit maintains a constant feedback current and eliminates the need for critical or frequency dependent feed back. The output voltage of an amplifier (3) is fed back to its inverting and its non-inverting inputs (12,11) via a capacitor (5) in a positive sense (5,6) and a negative sense (5,7,8) respectively. The negative feedback via diodes (7,8) comes into effect when these diodes conduct at a predetermined threshold voltage.

Title: Stepped dia. tube continuous prodn. - uses subsequent drawing operations with variable dia. dies and mandrels
Inventor: WASSEN HANS
IPC: B21C37/16
Filed: 1980-08-22
Abstract: The tube is first drawn through a die to form its final, larger, external diameter. The die cooperates with a mandrel fitted to rod. During the drawing process the tube larger diameter section reaches a segment drawing tool assembly which reduces the larger diameter to the required smaller size. The size of the smaller inner diameter is determined by the external diameter of a mandrel, forming a continuation of the first mandrel. The operation of the segment drawing tool assembly is intermittent. The actual reduction end of the drawing tool pivots on a fulcrum, and the pivoting movement is controlled by an arm which is swung for the reduction operation.
