Title: Hinged fitment for back rest adjustment of seats - is used in vehicles, and consists of two plates with spring loaded friction catch
Inventor: PUTSCH ULRICH DIPL ING
IPC: B60N2/22
Filed: 1978-11-20
Abstract: The hinged fitment is used for passenger seats in vehicles such as motor cars, with adjustable back-rests. The fitment consists of two plates (10, 11) which are mounted on pivots together with the aid of an axle. One plate belongs to the seat, and the other plate belongs to the back-rest. The two plates (10, 11) can be fixed by a spring-loaded friction catch (18, 20) which can be moved axially by a pressure disc (23). The plates (10, 11) are supported against each other with the aid of a tumbler gear. There are theeth between the friction catch (18, 20) pressing the plates (10, 11) against one another, and the pressure disc (23). The teeth have flat side faces at a shallow angle forming a low amplitude sawtooth pattern.

Title: Using arylalkyl azide cpds. as biocides - for sterilising and disinfecting oily and aq. liquids
Inventor: MOSER JOERG PROF DR
IPC: A01N41/04
Filed: 1979-02-08
Abstract: The parent patent describes the use of aliphatic 5-17C azides as biocides for sterilising and disinfecting oily and aq. liqs. In this addition arylalkyl azides (I) are used instead. Suitable (I) are benzyl-, tolyl-, phenyl (opt. substd. by Cl, F or CF3)-, toluenesulphonyl-, phenyloctyl-, phenyldecyl-, phenyldodecyl- or phenyltetradecyl azides, or azidotoluene sulphonic acid.

Title: Shaft connection for crane or crab running wheels - has lining bushes surfaced with sintered PTFE and lead
Inventor: NUESSLEIN RUDOLF DIPL ING
IPC: F16D1/04
Filed: 1979-07-17
Abstract: Bearing bushes are fitted between the whole inner circumference of a hollow shaft, and the outer circumference of a shaft which is plugged into it, and is driven by the hollow shaft through a key. The bushes present a sliding surface to at least one circumference, and they have a slot over at least part of their axial length, through which the key projects radially. The wall thickness of the bushes is selected at such a low level that the capacity of the key to transmit torque is not seriously reduced. The bearing bushes have a sliding surface formed by a sintered layer of a mixt of PTFE and lead. They may be formed from a laminate having a steel backing with an intermediate layer of tin and bronze powder, the pores of which are filled with a mixture of synthetic material and lead. The sliding surface formed on this is a mixt of PTFE and lead sintered as stated. The arrangement is partic applicable to the running wheels of cranes. The formation of rust which normally makes it difficult to separate the two shafts without special equipment, is prevented, and ease of dismantling is ensured.

Title: Viscose prepn. - by activating cellulose with energy radiation followed by treatment with sodium hydroxide soln.
Inventor: FISCHER KLAUS DIPL ING DR
IPC: C08B1/08
Filed: 1979-10-13
Abstract: Viscose is made by a combination of irradiation of cellulose with high energy radiation and alkalisation with aq. NaOH soln. Pref. the cellulose is irradiated with high energy electrons using a radiation dose of 1-30 kGgamma before alkalisation and treatment with 19%, esp. 16% aq. NaOH soln. The irradiation causes preactivation of the cellulose, with loosening of the structure and redn. of the degree of polymerisation. Alkalisation can be carried out with less conc. NaOH soln., and a prematuring stage can be omitted. The consumption of CS2, NaOH and H2SO4 in the process is reduced. Plant investment and running costs for the process are reduced.

Title: Brake blocking protection system for vehicle - uses spring-loaded piston with tandem main cylinder
Inventor: STUMPE WERNER
IPC: B60T8/46
Filed: 1979-10-20
Abstract: The system has a brake reducer (10) monitoring the through-path through a brake line (1,1'), 2,3). A modulator piston (14) belonging to the brake reducer is operated via a switching and safety piston (15) by a solenoid valve (18) under the pressure of the power supply device (21,22). A spring (19) acts on the switching and safety piston that brings the brake-reducer control valve (11) into the through-flow position when the power supply fails. The spring's force is set to a maximum braking pressure in the system and the control valve is simultaneously the maximum-pressure safety valve.

Title: Mine coal planing machine tools controlled engagement - involves push rod in guide rod linkage preventing excessive abutment swivel
Inventor: BLUMENTHAL GUENTER
IPC: E21C27/32
Filed: 1980-01-23

Title: Coin tester inlet channel - has deflector forcing smaller dia. coins into recess in side wall for rejection
Inventor: MOSINGER RUPERT
IPC: G07F1/04
Filed: 1980-02-28
Abstract: The coin inlet channel includes a dia. testing section (10) to separate out any coins that are too small. This prevents the stacking or manipulation of smaller value coins within the following coin tester so that they reach a receiving channel for higher value coins. The testing section (10) consists of a recess (11) formed in a side wall of the inlet channel (1). The upper edge (13) of the recess (11) runs parallel to the feed path (7) of the coins (4). Its (13) distance from the path (7) is slightly smaller than the dia. of an acceptable coin (14). The lower edge (15) runs in parallel to the path (7) at a smaller distance. A deflector (12) is assigned to the opposite side wall (6) of the inlet channel (1).

Patent DE-3012640-A1 (DE)
Inventor: FRANZ GUENTER DR ING
IPC: H01B13/04
Filed: 1980-04-01
Abstract: Guide heads (5, 6) are supported in supporting stands (1, 4) such that they can rotate. The guide heads (5, 6) are connected to one another in a rotationally fixed manner by means of a guide rod (7). The guide rod (7) is of circular cross-section and has a smooth sliding surface. The guide heads (5, 6) are driven by means of a splined drive (8) via the guide rod (7). A stranding material strand (13) is laid around the guide rod (7) in a helix having a large pitch. The guide rod (7) represents a reliable storage and guide element which reliably guides the stranding material strand (13) in a helix, it also being possible to change the pitch of the helix. As a result of the small diameter of the rotating system, the device permits relatively high rotation speeds. The threading in of the stranding material strand (13) is simple and uncomplicated. <IMAGE>

Title: Dual purpose wall and ceiling formwork system - has vertical girder with part between panels as part of form surface
IPC: E04G11/50
Filed: 1980-04-08
Abstract: For concreting walls or ceilings use is made of systematised formwork with a rectangular form panel (i). The panel is supported at its two narrow sides, to absorb normal ceiling loading, and at its two longitudinal sides, to absorb concrete pressure occurring in wall formwork. Support in its peripheral areas during wall concreting is provided by a vertical longitudinal girder (2), with a section (61,62) located between two form panels, to serve as part of the form surface. This girder is shaped so as to accommodate the tie bar for the wall formwork in this intermediate area. This enables panels to be used for both wall and ceiling work.

Title: Hydraulic boat rudder installation - has control valve adjustable against permanent resetting force, and has buffer in hydraulic servo-circuit for pressure compensation
Inventor: HERMES HANS
IPC: B63H25/30
Filed: 1980-04-11
Abstract: The hydraulic rudder control has a hydraulic control valve to regulate the flow of servo-fluid to the double-action servomotor. A feedback control is generated by a hydraulic reaction force proportional to the rudder deflection, with the control valve automatically set to provide the correct amount of servo-drive. The steering control is fully hydraulic and requires no complex electric sensors and feedback circuits. A hydraulic damper is included in the circuit to take up any sudden changes in torque and reaction forces.
