Title: 3-buten-1,2,3-tricarboxylic acid (ester) copolymers prepn for adhesive
IPC: C08F22/00
Filed: 1971-04-17
Abstract: Polymers of 3-buten-1,2,3-tricarboxylic acid and/or its esters derivs. are prepd. by polymerising vinyl monomer system of (a) 50 mol.% this acid and/or esters and (b) at least equimolar amount of polymerisable promoter-monomer with catalytic amount of vinyl polymerisation catalyst in miscible medium at appropriate temp. These polymers can be used for coating textiles, in surface coating systems, adhesives etc. Opt. plasticised polymers with Tg between -30 and -80 degrees are effective pressure-sensitive adhesives. This technique makes it possible to produce solid copolymers from acid and esters which exhibit strong steric hindrance and give only low-mol homopolymers.

Patent DE-2306942-A1 (DE)
Title: Bobbin winding - using cord from bobbin holder arm to guide rail round eccentric bush
Inventor: SLAVIK VALTER
IPC: B65H54/32
Filed: 1973-02-13
Abstract: Designed for winding yarn or thread onto a bobbin to give smooth sides and tapered ends, the growing dia. of the bobbin causes the bobbin holder arm to swing, pull on the cord, and thus restrict the throw of the reciprocating yarn guide. The eccentric bush delivers periodic impulses to the cord to impose a slight hesitation in the adjusting movement to slow down the rate of change, which could accelerate in the final winding phase, and prevent ridges in the winding.

Patent DE-2332309-A1 (DE)
Title: Independent road wheel suspension - has steering link rod dependent roll compensator
Inventor: RUF GEBHARD DIPL ING
IPC: B60G7/02
Filed: 1973-06-26
Abstract: To reduce roll on cornering, the effective load supporting spring length is altered correspondingly to compensate by means of a stop fitted to the steering link arm which turns a lever on its axis. The roll can also be reduced hydraulically in the case of hydraulic or hydropneumatic suspension by allowing the steering link stop to displace a hydraulic piston in a cylinder to exercise an influence on the hydraulic suspension system and raise the body work on the outside wheels. Basically it is possible to raise a mechanical suspension hydraulically and a hydraulic system mechanically.

Patent DE-2340989-A1 (DE)
Title: Steerable ski bobsleigh - has runners hinged sideways to seat support frame
Inventor: BOEHM GERHARD
IPC: B62B13/12
Filed: 1973-08-14
Abstract: The ski bob is provided with hand levers which cause both runners to tilt on their edges to effect a turn. By moving the lever to one side, the runners turn on to their respective right edges and on to the left edge when the lever is reversed. The levers are connected to force a parallel movement of the runners, a spring returning them to normal position. An additional steering aid is given by providing a claw at the end of each runner and actuated by a pull wire in an outer sleeve from the hand levers. The hand lever bar is fixed directly to the runner which is hinged at the front and rear to the seat support bars.

Title: Plug-in switchboard for telecommunications systems - permits use of prefabricated links having standard lengths
Inventor: KUENKLER FRITZ
IPC: H05K7/18
Filed: 1974-02-08
Abstract: The terminals for the telecommunications switchboard are arranged in columns and grouped according to functions. Below each column are groups of hooks which serve to hold the interconnecting wires. The adjoining columns thus give rise to vertical and horizontal rows of hooks round which the wires can be threaded to keep them tidy by taking up any slack caused by having to use a standard length which does not quite fit. The wires can also go directly between terminals in one column.
Patent DE-2415222-A1 (DE)
Title: Cable entrance in concrete wall - has clamps allocated to connecting piece, or formed by it
Inventor: HAUFF WERNER GERHARD
IPC: H02G3/22
Filed: 1974-03-29
Abstract: Clamps safely hold in the wall the connecting piece of the wall entry. The clamps are actually connected with the connecting piece and lock it in the entry. They are inserted into slots in the connecting piece collar, and are locked in it by projections; or they are formed by the recess wall itself. The wall entrance connection of the main patent has proved itself adequate for all normally encountered stresses and strains. Extreme loads such as enduring, strong pulling actions and regular shaking of the wall can however loosen the connecting piece. The present form avoids the possibility of this danger.

Title: Automatic steering using laser beam - beam digitised by oscillating mirror on cab and signal period compared with mirror period
Inventor: HAGEN HANS DR ING
IPC: G05D1/02
Filed: 1974-05-15
Abstract: An automatic steering system for road vehicles uses a laser beam (4) that is generated from a sender/receiver unit (3) and which is reflected downwards by a pivotted mirror (5). The laser beam is directed at a reflection, band running along the required road course. Reflected light (4a) is directed by the mirror to the sender/receiver unit (3). The mirror is oscillated at a fixed frequency and in consequence. The reflected beam is converted into a series of light pulses. Comparison of the period of the light pulses with the period of the mirror oscillation is carried out in the control unit (13), that also has a number of reference inputs (23), relating to vehicle speed etc.

Title: Graviscope for gravity waves measurement - has mechanical wave transformer mounted on cylindrical block
Inventor: BSCHORR OSKAR DR RER NAT
IPC: G01H1/00
Filed: 1974-06-18
Abstract: The transformer continuously tapers, and its thin end is terminated by an oscillation sensor, reflection-free and with matched impedance. In order to reduce the wave transformer length, it is folded back or helically wound. Longitudinal waves of the block are transmitted as flexural waves by a transversal waveguide, and transformed to a smaller cross-section. The wave transformers thin end is in the form of a wire and acts as oscillations indicating sensor. In order to find direction and position of gravity waves, two or more systems are used crossing, or at a distance from each other.

Title: Ceramic distance piece for separating HF cables - has an annular groove formed at each end of the ceramic body to locate the cable
Inventor: HUEBNER MAX
IPC: H01B17/16
Filed: 1974-10-31
Abstract: The application is particularly to the support of leads to aerials and symmetrical high frequency conductors, and is intended to relieve the distance piece of torsional stresses. The ceramic rod (1) has an annular groove (2) at each end whose profile has no sharp edges. The cable (8) is roughly located by this groove and is then held in position, typically by lashing with a wire which allows a certain degree of elasticity. Alternatively the cable may be held by a clamp comprising two rings with a large clearance hold for the rod. The two parts of the clamp are then pulled together by a nut and bolt (14, 13) until the clamp faces grip the cable.

Title: Hydraulic damper esp. for vehicle bumpers - has flow restrictor with temperature compensation
Inventor: HAHN ERICH
IPC: F16F3/10
Filed: 1974-12-18
Abstract: Impact damper esp. for supporting bumper bars of road vehicles comprises a pair of telescopic tubes (10, 11) one of which has a flow restrictor so that when the tubes are pushed together the impact is damped by the flow of a liquid from the one tube into the other being restricted. To compensate for reduction in the viscosity of the liquid with increase in temperature a spring-loaded valve member controlling flow through the restrictor is connected to an expansion element (24') e.g. an air spring, responsive to an increase in temperature to increase the force which the flow has to overcome to open the valve.
