Title: Switch for motorcycle mounted radio receiver - has actuator on receiver housing surface whose tipping axis is within surface plane and has automatic resetting
Inventor: HAUSER FRANZ ING GRAD
IPC: G11B15/10
Filed: 1978-09-22
Abstract: The switch (1) is intended for a motorcycle mounted radio, radio-telephone or tape cassette recorder. The respective apparatus housing (3) has a large actuator (4) on its surface (2). The tipping axis (5) of the actuator lies in the housing surface, and the oscillator can be reset into its rest position automatically. For this purpose a resetting spring (6) abuts the housing and reaches underneath the actuator. To the latter may be allocated a switching element (7) which can assume a rest and a switching position respectively, while being decoupled from the actuator in its rest position. The switching element may be held in a flexible diaphragm (8), closing a housing aperture (9). The switching element may break a light carrier (10) in one of its positions.

Title: Control mechanism for aerosol jet - has eccentric lever acting on jet valve through overcentre cam pivoting on wire clip
Inventor: TEMPELMAN ANTHONIE PETRUS
IPC: B65D83/16
Filed: 1978-10-04
Abstract: For continued spray operation, the operating lever is depressed and stays in a self-locked position until lifted manually. The lever is fitted to the neck part of the can (3) by a wire clip (9) partly surrounding the rim (2) of the neck, with arms (9b, 9c) towards the centre of the can, where the ends of the wires serve as fulcrums for the operating lever (7). The end of the lever containing the fulcrums has a cam part (8a, 8b) resting against shoulder (5) fitted to the tube (4) containing the spring-loaded valve assembly terminating in the jet orifice (10). By depressing the lever the valve inside the tube opens and spray is ejected from the can.

Title: Irrigation accessory for agricultural use - consists of hose drum turning in bracket slewing on axis perpendicular to drum axis
Inventor: HEIN HARTMUT
IPC: A01G25/09
Filed: 1978-12-21
Abstract: The agricultural irrigation accessory comprises a drum accommodating connecting hoses. The drum (2) turns in a bracket (3), which in turn slews about an axis (6) perpendicular to that (5) of the drum. The slewing axis can be clear of the centre of gravity of the drum, but by an amount small enough to keep the overall dimensions to a minimum. The slewing axis can be formed by a tube (7) fitting inside a guide sleeve (8), and attached to the bracket at the top by a pivot pin (12).
Patent DE-2856749-A1 (DE)
Title: Standby control circuits and equipment for automatic exchange - enables transfer operation from defective to reserve equipment upon interruption
Inventor: POLLACK WOLFGANG
IPC: H04Q3/54
Filed: 1978-12-29
Abstract: An automatic exchange has main and decentralised local controllers. The main controllers are duplicated and have associated supervisory and switching units. The local units have a controllable selector which can be set for one channel or the other. The main switching units are connected by signal and power supply leads to the local selector inputs. The main controllers have duplicated connections to the local units. A fault in the operating channel interrupts the corresp. local connections and transfers control to the reserve main unit which makes the appropriate reconnections. A faulty main controller can then not interfere with further operation of the exchange.

IPC: F27D21/02
Filed: 1979-02-01
Abstract: The connection device is for the interior of a pressure-type coal gasifier whose metal wall is lined with refractory material which is to be linked to an external measuring instrument. A pipe (17) connected to the interior (19) extends only halfway through the lining (11) to a recess (21) formed in the latter. A further pipe (15) connected to the recess and offset from the first one, passes through the wall (10) to the instrument, being so positioned that no appreciable radiation from inside of the gasifier can penetrate into it. A tubular sleeve (20) may surround, on the metal gasifier wall, the pipe penetrating to the recess.

Title: Optical inspection unit for quality control - has TV camera scanning tested and reference objects for correcting video signal
Inventor: YOSHIDA HAJIME
IPC: G07C3/14
Filed: 1979-04-20
Abstract: Elimination of incorrect inspection of objects is ensured by comparing light intensity reflected from a reference unit with that due to the tested object. TheTV camera (3) takes the image of the reference object (1) using a white paper (5) for the calibration. The viewing field of the camera is illuminated by light source (2). The signal dereived from the reflection from the calibration paper (5) is fed to a circuit (4) which ensures the correction of the video signal from the camera. The corrected video signal is then discriminated against the video signal derived from the tested object by the comparator (43) for deciding whether a match exists between the tested object and the reference object. The method provides reliable inspection irrespective of ambient conditions.

Title: Powered laster for shoe heel seats - has wipers moved longitudinally along shoe with nail pattern set by stroke limiter
Inventor: GIEBEL GERHARD
IPC: A43D21/16
Filed: 1979-07-16
Abstract: The tack seat laster has the wipers (90) moved length-wise of the shoe and inwardly under the action of a single piston-and-cylinder (74,72). For setting the appropriate nail pattern, the action of the piston-and-cylinder is terminated by an adjustable stroke limiter. This comprises a valve (142) actuated by an abutment (148-146). The valve moves with the wipers. The abutment is adjustably positioned in the path of the valve. A second abutment, spaced from the first abutment, controls the rest position of the wipers. The wipers are arranged symmetrically centrally of the machine. The heel band clamps a shoe in the position in which it is presented by the operator, avoiding the need to adjust the wipers for lefts and rights.

Title: External drive for pressure vessel mechanism - with freewheel device actuated by hydraulic power cylinder
Inventor: KIESLING HORST-EBERHARD VON
IPC: F23H13/08
Filed: 1979-08-04
Abstract: Drive for a rotating gear inside a container which is at a high pressure and temp., for example the revolving grate of a reactor for coal gasification under pressure is fitted on the vertical drive shaft of the grate with a free-wheel device. A hydraulic power cylinder with water cooling reciprocates the free-wheel casing to revolve the grate intermittently. This eliminates the highly stressed pinions of gear drives and their sliding ring seals. The new drive has a higher functional reliability.

Title: Measurement circuit for calibration equipment - measures time for integrator to ramp voltage between two accurately defined levels, esp. for adjustment
Inventor: PILZ JOCHEN
IPC: G01R27/26
Filed: 1980-02-22
Abstract: The measurement circuit with a direct voltage source (27) is esp. applicable to alternating voltage integrators of calibration equipment with accurate transfer characteristics, and enables the transfer characteristics of such equipment to be measured and adjusted. Partial voltages from a potential divider are input, with a voltage fed to a direct voltage integrator (20) from the direct voltage source, to a comparator circuit (29). The comparator circuit drives a logic circuit (30) which outputs a signal corresp. to the time constant of the direct voltage integrator RC element (22,26). The precision voltage divider (28) places 0.9 and 0.1 times the source voltage on the comparator element (36,37) inputs. When the integrator switch (42) is opened the output voltage (U3) rises linearly, causing the comparator elements to trigger as it passes the two threshold values set by the potential divider (28).

Patent DE-3025472-A1 (DE)
Inventor: LECZKOWSKI KURT
IPC: F01K25/10
Filed: 1980-07-04
Abstract: According to this method, a gas medium is selected as a working medium for which the isobaric curves represented in a temperature-enthalpy diagram to the right of the junction line joining the summits of successive isenthalpy curves (line VS-I), are substantially directed downwardly to the right hand side. A substantially constant gas quantity is repetitively exposed to a dextrogyre cycle, from a starting state (point 1) at an increased pressure and substantially at room temperature. The working medium is first expanded (point 1 to point 2) to lower its temperature and to obtain a work, and then it is exposed to a pressure increase (point 2 to point 3) and it is finally brought to the starting state (point 1) by an environment heat flow.
