Title: Plastics connector for electric conductors - has elongated, flexible strips of length permitting various combinations with other connectors
Inventor: SCHOLTHOLT HANS
IPC: H01R4/24
Filed: 1980-06-27
Abstract: The connector has at least one terminal for electric conductors, and several such connectors are interconnected by separable strips (4). The latter are of strip or line-shape and of such length that the spacing, angular position and/or alignment or offsetting between adjacent connectors (1) are adjustable. In this manner a connecting strip of high flexibility, but sufficient rigidity can be obtained. Pref. the band-shaped strips are arranged orthogonally to one fastening side of the connector. Alternatively, the strips are aligned with one connector outer surface. The strips may be arcuated and may extend obliquely to the position of the individual connectors. In this manner a highly individual manner of application is possible, without disconnection of the fastening strips.

Title: Refrigerating compressor disc valve - extends beyond seat to form venturi passage with surrounding wall face
Inventor: WOLFF JOHN BONNESEN
IPC: F04B39/10
Filed: 1980-08-16
Abstract: The valve is for a machine with a reciprocating piston, esp. a refrigerating compressor. Its plug consists of a disc inserted loose and working between a seat on a wall and a stop. The disc is pref. flat. The disc (1) protrudes outwards beyond the seat (2), and the distance between it and the wall face (11) towards it decreases in the radial direction towards the seat continuously, so as to form a venturi- type passage (20) for the inwards-flowing medium until the valve shuts.

Title: Target signal extraction from received, interference-laden signals - uses mean gap in environmental signal during mean value formation on received power and comparison with expected threshold
Inventor: HERMSTRUEWER GUENTHER DIPL ING
IPC: G01S3/04
Filed: 1980-09-22
Abstract: The extraction takes place during direction finding and for each received angle is referred to a measured received power to an estimated interference output in each environment interval of the angles. During the mean value formation at the point of the associated received angle, a mean value gap in the environment interval is preset and the standardised received power is compared with an expected threshold. If the threshold is exceeded a continuous mean value formation of the modified powers and their standardisation are repeated on the base of the newly obtained mean values, until a standardised modified power is without excess of the expected threshold. The first modified power and further such powers are obtained from the previous modified powers obtained by the mean value formation.
Patent DE-3044622-A1 (DE)
Inventor: THIEME GUENTER
IPC: B42B2/00
Filed: 1980-11-27
Abstract: Arranged in a segment-shaped recess (18) is a cluster gear (11) which can be pivoted about the two counter-gears (9, 13). The cluster gear (11) is mounted on an axle (19) which is fixedly connected to an oscillating crank (16). The oscillating crank is for its part rotatably arranged on the common axle (17) of the two counter-gears (9, 13). An adjustment of the oscillating crank (16) causes the cluster gear (11) to roll on the counter-gears (9, 13). Depending on the direction of adjustment, the output shaft (5) thus runs ahead of or behind the drive shaft (7) and this produces a changed seating of the inserted wire staples (3). The insertion of the wire staples (3) into the individual signatures (1) during the running of the machine is so regulated that, in the finished book, the wire staples are offset in the signatures (1) situated next to each other. <IMAGE>

Patent DE-3049388-A1 (DE)
Title: Power generator operating with heated fluid - has pistons of slidable cylinders linked by lever system which provides constant movement
IPC: F03G7/00
Filed: 1980-12-29
Abstract: The drive uses movable bodies with lever system operating under tension to maintain the bodies under constant movement. An atmospheric excess pressure generated by a low/high pressure cylinder generates the tension pressure. The piston and the cylinder head of the compression cylinder each transmit the excess pressure, via a lever system, in the same direction, onto one or a common pressure receiver on the body to be moved. The receiver prevents pressure relief.

Title: Process for generating protective gas from the off-gas of furnaces heated by radiant tubes
Inventor: KLIX JUERGEN
IPC: C01B3/48
Filed: 1981-02-07
Abstract: So as to generate protective gas from the off-gas of furnaces heated by radiant tubes (radiant-tube furnaces), there is burnt, in some of the radiant tubes of the furnace, a constant amount of fuel gas with a small deficit of air. Expediently, so many radiant tubes are employed in this manner that the constant amount of heat generated can be used to cover the heat losses of the furnace. The off-gas of these radiant tubes is then freed in a conventional manner of noxious constituents such as CO2 and H2O in a gas regeneration plant.

Title: Automatic fire-extinguishing system for vehicles used in underground mining
Inventor: PETRY HANS-JUERGEN
IPC: E21F5/02
Filed: 1981-06-10
Abstract: Such a fire-extinguishing system consists, in principle, of a fire-extinguishing bottle, located on the vehicle and having an outflow connection piece for powdery extinguishing agent and of a voltage source for providing the ignition voltage for the ignition capsule arranged on the fire-extinguishing bottle. To avoid the need for the hitherto necessary visual fire detection and initiation of the extinguishing operation by means of a crank inductor by the vehicle driver, there is a fire-warning sensor, the signals of which can be detected continuously in a testing and triggering unit which is assigned as a voltage source an inherently safe battery and which, after a predetermined limit value has been exceeded, triggers an alarm, and switches a potential-free contact, especially for stopping the vehicle, the triggering of the alarm applying the battery potential to the ignition device.

Title: Screw for screw extruders or injection moulding machines
Inventor: MUELLER FRIEDRICH
IPC: B29C48/85
Filed: 1981-10-01
Abstract: For temperature homogenisation of polymer melts in screw extruders or injection moulding machines, in addition to the hollow space extending in the axial direction, the screw (2) has circumferentially distributed, radial heat-conducting cartridges (14) which project through the screw core (8) into the hollow space and around which the heat-transfer medium flows. The heat-conducting cartridges (14) may be in the form of heat-pipes (heat-pipe pins) which are individually hermetically sealed and only partly filled with a heat-transfer liquid, or may be open at their base ends (140). The screw core (8) itself may also be designed as a heat pipe or, on the other hand, may be connected to an external temperature-control system for the circulating temperature-control liquid (16). The use of the measures according to the invention is advisable in particular in the processing of shear-sensitive and heat-sensitive polymers and other polymers which are difficult to handle and for the dissipation of locally occurring frictional heat. <IMAGE>

Title: Method for monitoring an alternate voice transmission system
Inventor: HAUSER FRANZ
IPC: H04B17/309
Filed: 1981-10-12
Abstract: In a method for automatically monitoring a wireless alternate voice transmission system, a transceiver operating in receive mode is switched over to send mode and a transceiver operating in send mode is switched over to receive mode periodically during a short time interval in all transceivers communicating with one another. The transceiver temporarily operating in receive mode determines whether it receives the transmission pulse to be transmitted by the transceiver temporarily operating in send mode. If it does not receive this pulse, the alternate voice transmission fails and a warning signal is generated. A failure of this type in the alternate voice transmission system which is to be identified may be due to a distance between the transceivers communicating with one another which is too great in terms of the predefined transmission range or due to an operational fault in the sending or receiving transceivers.
