Title: Needle type printing mechanism electromagnet - has spring-loaded plunger sliding between end cap and core in former
Inventor: MAEDA KATSUMI
IPC: B41J2/285
Filed: 1979-08-02
Abstract: The electromagnetic control unit is for a neelde-type matrix printing mechanism. It has a coil wound on a cylindrical former (21) and a stationary magnetic core (13) with a cylindrical portion (27) inserted in a central bore (23) of the former from the front. A plunger (16) slides in this bore, and an end cap (17) secured to the former has a portion (44) opposite the plunger rear end, which is spring-loaded against it (50). This leaves a gap of set length between plunger and core. A yoke (12), acting as a housing, forms a magnetic circuit from core to plunger when the coil is energised, and a printing needle (15) passes through a central opening in the core and is fixed to the plunger at its rear end.

Patent DE-2934832-A1 (DE)
Inventor: STETSON EARL WILLIAM
IPC: H01C1/084
Filed: 1979-08-29
Abstract: In the case of an over voltage protection device having a heat transmission device, a disc-shaped zinc-oxide varistor (16), which has an upper and a lower electrode layer (20) as well as a ceramic ring (21), makes thermal contact with a metal disc (23), as a heat sink, with the aid of an elastic sleeve (22) and a spring force which is to be exerted axially; the heat produced in the varistor (16) is quickly dissipated into the metal disc (23). In the over voltage protection appliance (10), a flexible filling body (24) presses the varistor (16) against a housing (11), as a result of which heat is transmitted to said housing. In consequence, the heat-dissipation capability of the varistor (16) is achieved with greatly reduced production costs. <IMAGE>

Title: Semiconductor circuit evaluating coded digital signals - extracts clock pulses from received signal using phase-shifted oscillator and fixed, stipulated valve oscillator
Inventor: PRELLER PETER DIPL ING
IPC: H04L7/033
Filed: 1980-06-19
Abstract: The semiconductor circuit has two oscillators (01,02) each coupled to a respective frequency divider (Te1, Te2). One of the oscillators (02) has a fixed frequency (f2) and is coupled together with its frequency divider (Te2) in a frequency regulating loop for the other, variable, oscillator (01). During a first phase the digital signals are serially applied to the variable oscillator (01) and the oscillations delivered by the latter exhibit phase shifts controlled by the flanks of the digital signal. During a following phase the digital signals are blocked and an oscillation with an approximation to the same frequency is obtained using a required value provided by the fixed oscillator (02). The two phases are alternated according to a given working cycle, with a difference pulse (Pd) for each cycle fed to a shift register (SR). The latter supplies as output to the evaluation stage (AW) which feeds regulating pulses (Ri) to the variable oscillator ()1) via a resistor (R).

Title: Passive radar-effective direction finding unit - uses inflatable shell with internal metallised radar reflector
Inventor: STUERZENBECHER BRUNO
IPC: H01Q1/08
Filed: 1980-08-26
Abstract: The passive bearing unit consists of an inflatable textile shell, cylindrical in shape, containing an internal radar reflector (11), in the form of a triple mirror with triangular surfaces (12) which are also made of a textile material.

These join the corner points (14) of the reflector (12), and run orthogonally to the inner cylinder wall. The inflatable shell (10) has a connector support (15) below, for connection of the air supply, and is provided with an eye (16) above the reflector for suspending the device from the rescue island e.g. lifeboat. This radar reflector unit is easily inflated and is suitable for relatively small rescue craft.
Patent DE-3034368-A1 (DE)
Title: Vibrator for homogenising cement - has bimetal cut=out protection switch for motor inside on=off switch housing
Inventor: FRAUHAMMER KARL
IPC: E04G21/08
Filed: 1980-09-12
Abstract: The tube (2) connected to the vibrator (1) contains the electrical connections which supply the electric motor built into the vibrator cylinder (1). In two of the three current conductors (9) in this tube (2) motor protection switches made of bimetal are switched in line so that the motor current flows through them. When the vibrator cylinder is immersed in cement and switched on, the out-of-balance weight inside it is set in motion. Should a defect, such as discontinuity due to vibration, occur in one of the conductors, the motor will phase and an overload current will be drawn by the intact conductors. This overload current will heat the bimetal, which will cause the motor to switch off in due course. Since the motor protection is built into the on/off switch and not the vibrator motor windings, its life is greatly extended.

Title: Super-stoichiometric, modulating atmos. gas burner - is supplied with air by boosting fan, whose output is controlled in response to gas flow
Inventor: GOESSER HERBERT
IPC: F23N1/02
Filed: 1980-10-15
Abstract: The required combustion air is forcibly supplied to the burner by a ventilator whose output is accommodated to the actual combustion gas flow by speed adjustment via regulating member.

The regulating member can be of capacitive, infra-red, photo-sensitive, high frequency or mechanical type as appropriate. Preferably, the ventilator is controlled via a flowmeter with a conical tube, containing a sphere lifting in the gas stream and forming the flow sensor. The control may be carried out by a diaphragm, incorporated between the regulator and a gas nozzle. The control may be carried out at the ventilator drive motor by regulating the speed both by phase control and frequency change.

Inventor: BLUETHGEN BJOERN
IPC: H03M3/02
Filed: 1981-02-27
Abstract: A method for encoding analog signals for storage or transmission includes the steps of sampling momentary values of the analog signals and converting the sampled values into PCM code words and forming PCM differential code words from two successive PCM words, each of the differential PCM words being of a prescribed length. The length of the generated differential PCM words are continuously compared to a reference code word and upon the length of a differential code word exceeding a specified length the word is either abbreviated by a companded differential PCM word by eliminating some of the least significant code elements, or by division of the excess-length word into two successive code words respectively comprising the least significant and most significant bits of the excess-length word, the differential PCM words additionally being replaced by PCM words when the associated signal content does not exceed the length prescribed by the reference code word.

Title: Method for closing the holes for accommodating the fastening screws in installed work guides and a machine with holes in the work guides closed by this method
Inventor: STRATHMANN GERHARD
IPC: F16C29/08
Filed: 1981-03-11
Abstract: Holes in work guides of machines are closed at the top by introducing a curable sealing compound into the holes and then inserting a disc-shaped plug of the same material as the work guide in each hole. This disc-shaped plug is advantageously dimensioned in such a way that it rests on the head of the respective fastening screw and any part of it projecting above the respective hole is then ground off. In a machine produced by the above method, the disc-shaped plug (6) has a downward-pointing projection (7), similar in shape to the stem of a mushroom, to ensure that it is held firmly in the sealing compound and hence in the hole (2). <IMAGE>
