Patent DE-2404598-A1 (DE)
Title: Motor vehicle seat with adjustable back rest - has cranked inertia transfer bar to couple and lock adjustment
IPC: B60N2/22
Filed: 1974-01-31
Abstract: To avoid the danger of the back rest becoming unlocked in the event of a rear collision and allowing the seat occupant to fall backwards, the back rest locking mechanism on both sides of the seat is connected by an inertia sensitive cranked coupling bar. In order that the opposite effect does not occur in the event of a frontal collision, whereby an unlocking of the back rest pivot could happen, a spring whose strength of greater than the inertia exercised on the transfer crank pulls a catch hook which locks the back rest.

Title: Single conductor safety plug and socket - wire to plug and socket to wire connected only with plug fully inserted
Inventor: GARDEI HEINRICH
IPC: H01R13/703
Filed: 1974-02-05
Abstract: The single conductor safety plug arrangement is used for voltages above 42 V in laboratories. In the plug, the conductive connection between plug pin and conductor to the plug is only established if the internal two sliding contacts (one contact set connected to the plug pin, the other set connected to the lead-in conductor) in the hollow insulating plug body are connected by a conductive ring which is fixed to the coupling socket of the arrangement. In the coupling socket two separate connections are made when inserting the plug. The first connection is made by the plug pin between the metal sleeve internal in the socket and the lead-out wire and the second contact between the plug pin and the lead in conductor.

Title: T.V. camera for microfilm reading and photographing - has zoom objective with special setting method
Inventor: KIRSCH CARL MARTIN DIPL ING
IPC: G02B7/10
Filed: 1974-06-18
Abstract: Gaps between frames appearing in the camera video signal are detected and counted, and the magnification, starting from a minimum value, is changed until no more are counted. Picture content in the video signal is integrated and then differentiated. Gaps between frames appearing as zero crossings of the differential signal are counted. Film position is continuously corrected during the zoom objective setting, so that the frame vertical centre line coincides with the zoom objective optical axis. Brightness of the t.v. picture at its vertical edges is tested by scanning the beginning and end of the video signal picture content.

Title: Draining system for liquid gas tanker compartments - uses immersed jet pumps and hydrostatic pressure of gases for transfer
Inventor: HOFMANN ALBERT DIPL ING
IPC: F17D1/14
Filed: 1974-12-20
Abstract: An arrangement for draining a large number of containers containing low temperature liquefied gases without significant excess pressure in a short time, uses an actuating flow generated by a circulator pump (3) by means of immersed, jet pumps (5) into a collector vessel (2). The liquefied gases are transferred from this collector vessel by at least one transfer pump (4) to the destination. Liquified gas itself is used as the actuating flow. The gas pressure in the upper region of the liquified gas container (1) is regulated so that they hydrostatic pressure in the region of the immersed jet pump is held constant during the whole draining procedure.

Title: Mfr of universal joint slide bearing - with PTFE layer deposited on spherical bearing surfaces
Inventor: KRAUSS DIETER ING GRAD
IPC: F16C33/20
Filed: 1974-12-20
Abstract: The bearing which is e.g., used in a linkage, consists of an inner ring and a slotted or split outer ring. A layer of matl. with low coefft. of friction, e.g., PTFE is deposited on the bearing surface. The matl. on the bearing surface consists of a fabric with particles of the low friction matl. and a duro-plastic resin e.g., phenol resin which is embedded in another fabric. The matl. is compressed under heat, so that the duro-plastic resin transfers from the A- to the B-condition. The pre-pressed layer of low friction matl. is pressed in the outer ring under application of heat so that the duro-plastic resin goes over from the B-into the C-condition.

IPC: H04R1/10
Filed: 1975-04-16
Abstract: The headphones consists of a hollow U-shaped channel that fits over the wearer's head and has a sound reproducer at the base of each arm directed towards the listener's ears. The reproducers (2) are acoustically coupled via the hollow channel (1) passing over the top of the wearer's head. To achieve different acoustic effects by reflecting the sound within the channel, the two reproducers can be pivoted or rotated on their mountings at the bottom of the hollow arms.

Title: Mole trap arranged above burrow - has parallel vertical spikes with cam mechanism released by passing mole
Inventor: HASSELER THEODOR
IPC: A01M27/00
Filed: 1975-07-24
Abstract: The support-stake (3) inserted into the ground has guides (4) for a vertically-moving lifting-mechanism (5). At the bottom of the lifting-mechanism (5) is a plate (6) with long vertical spikes (7) on its underside. The top of the lifting-mechanism (5) has a tightening-hardle (8). The lower guide (4) has an attachment for two tension-springs (13), the other ends of which touch a plate (14) fixed to the lifting-mechanism (5). When the lifting-mechanism is raised by the tightening-handle (8), the springs are tightened. Earth falls into the mole-tunnel, leaving a depression (15) in which the release head (10) rests. The mole (16) pushing up the soil presses the release-knob (10) up, operating the mechanism and releasing the cam (11) on the lifting-mechanism (5). The lifting-mechanism is pushed into the soil, so that the spikes kill the mole (16).

Title: Cooling arrangement for salient pole rotor windings - has heat pipes with evaporator ends embedded in coils and condenser ends in gas flow
Inventor: FLEMING FRANCIS WILLIAM
IPC: H02K9/20
Filed: 1975-07-30
Abstract: The removal of waste heat from the windings of a salient pole rotor is assisted by embedding heat pipes (16) in the coils. These pipes are placed such that the evaporator ends are inside the mass of the coil whilst the condenser ends are located in the cooling gas flow. Typically a line of heat pipes (16) is placed at a point roughly half way through the coil thickness of a multilayer winding. The condenser ends project through the bottom of the coil into the gas duct (14) between adjacent poles. Alternatively the heat pipes may lie axially in the windings with their condenser ends projecting into the gas space at the machine ends just outside the coil noses.

Patent DE-2601081-A1 (DE)
Title: Delivery unit for overlapped paper sheets - has rear sheet edges diverted by reduced air pressure to prevent excess friction
Inventor: MATTHEWS MERTON LOUIS
IPC: B65H29/66
Filed: 1976-01-13
Abstract: The unit for delivering overlapped sheets avoids collision between the rear and front ends of each following sheet. The individual sheets are moved at a relatively high speed from one position in a second position. When the front end of a sheet arrives at the second position the sheet is moved further at a relatively slow speed so that it is overlapped by a following sheet. Adjoining the second position is an area of a reduced pressure which diverts the rear end of a sheet moving over the area from the delivery plane of the front end of the following sheet and so enables their overlapping. The area of the reduced pressure is produced by an air stream blown against delivery direction of the sheets.
