Title: Device for generating and radiating ultrasonic waves in sweep mode which have a deterrent effect on cats and dogs
Inventor: GERBER ILSE
IPC: A01M29/18
Filed: 1983-05-04
Abstract: The portable device is used to prevent bite wounds, attacks and obstruction from dogs affecting persons employed in the public services, sportspersons, small children, walkers and blind persons, and to prevent fouling of public and private land by dogs and cats. To prevent dogs and cats from approaching persons and from remaining on a specific piece of land, electronic frequencies in the ultrasonic range above 20000 Hz, which are inaudible to the human ear, are generated by the electrically operated device and radiated at a specific sound pressure in sweep mode in a conical sound field.

Title: Adjustable lifting rod on the three-point trailer device of tractors or the like
Inventor: CONRAD ERNST
IPC: A01B59/00
Filed: 1983-05-06
Abstract: The invention relates to an adjustable lifting rod on the three-point trailer device of tractors or the like, consisting of two parts which are connected to one another in a frictional manner via a screw spindle, one part of which is coupled by its head to the lower link and the other part of which is coupled by its head to the force arm, the screw spindle being rotatable via an angular gearing using a handle by a shaft arranged transversely with respect to the screw spindle. The invention makes it possible to adjust the lifting rod even when a load is coupled and to secure the selected adjustment. The invention consists in the fact that the handle is connected to the shaft via a switchable ratchet (cat rake) and that the shaft is provided with at least one recess with a level floor, into which recess the securing element can be inserted, the said securing element being connected to the head of the lifting rod part in a positively engaging fashion in a secured position.

Patent DE-3342003-A1 (DE)
Title: Electrically operated apparatus having a theft protection device
Inventor: HAGAN HENRY
IPC: E05B49/00
Filed: 1983-11-22
Abstract: An electrically operated apparatus (10), for example a video recorder, is described, which has a theft protection device (15) using a data memory (22) which is preprogrammed with protection data; furthermore, the theft protection device contains a data input apparatus (23), a data comparator (21) whose output signal controls the state of a switch (20) which is located in the power supply line (13, 16) of the apparatus and, in the closed state, connects the normally provided control circuit (12) of the apparatus (10) to the mains. The switch (20) can be closed only by the same protection data as that contained in the memory (22) being entered by means of the input apparatus. In this case, the comparator (21) causes the switch (20) to close. A latching circuit (17) whose output once again leads to the control input of the switch (20) is connected to the power supply line (16) which leads from the switch (20) to the control circuit (12). The latching circuit (17) causes the switch (20) to remain switched on until the power supply to a point located in front of the switch (20) is interrupted. This allows the input apparatus (23) to be used for two purposes, namely not only in the context of theft protection (15) but also for controlling the regular operating sequences of the apparatus (10). <IMAGE>

Title: Brake pressure control unit
Inventor: SCHOPPER BERND
IPC: B60T11/34
Filed: 1983-12-02
Abstract: A brake pressure control unit for a pressure medium operated dual circuit vehicle brake system is proposed, in which the control valves (7, 8) of each brake circuit (I, II) lie in series in a housing (1) and in which the control pistons (14, 14') of the control valves (7, 8) can be displaced in opposition to one another into the closed position as a function of the pressure. The two control pistons (14, 14') are acted upon by a common control spring (10) and the mutual spacing of the valve seats (20, 20') assigned to the control pistons (14, 14') can be varied. In the event of a variation of the mutual spacing of the valve seats a uniform variation in the reversing pressure is achieved by very simple means in both brake circuits (I, II) by the control spring (10) common to the two control pistons (14, 14') and the uniformity of the brake pressure build-up during the pressure-reducing phase is improved. <IMAGE>

Title: Vehicle, in particular for underground mining operations
Inventor: GOULDING KEITH
IPC: B62D49/04
Filed: 1984-09-03
Abstract: A vehicle which is particularly suitable for underground mining operations has a first and second vehicle component, each vehicle component having at least two wheels and the vehicle components being pivotable with respect to one another about vertically extending joints, which purpose can be served by hydraulic cylinders. Implements, for example a shovel, which serve for transporting and handling materials and devices, can be attached to the first vehicle component. In the first vehicle component, a control station for an operator is also provided whilst the drive motor is located in the second vehicle component. By virtue of the fact that the operator is accommodated on the same component of the vehicle to which the implements are attached, it is possible to arrange all the components serving for the actuation and movement of the said implements in the first vehicle component so that the first vehicle component is an independent component which can be uncoupled from the second vehicle component and can be replaced by a similar first vehicle component which is designed to carry out other functions than the previous one. <IMAGE>
