Title: Control mechanism
Inventor: SUIMON YOSHIO
IPC: A63H17/36
Filed: 1981-12-30
Abstract: A control mechanism is described for use in a moving toy such as a toy car. The control mechanism has a supporting housing which is fitted on a part of the chassis of the toy such that it can rotate freely to the left and right. The supporting housing supports in a movable manner a pair of arrangements, each of which has an essentially U-shaped soft-magnetic element and a coil which is wound around a suitable part of the soft-magnetic element. The supporting housing furthermore supports, such that they can rotate, two separate parts of the tyred wheel shaft at such a position that these parts of the tyred wheel shaft magnetically attract both ends of the respective U-shaped soft-magnetic element and can touch them when current flows through the associated coil. When the coil is supplied with power, the soft-magnetic element is magnetically attracted and is touched by the associated part of the tyred wheel shaft at its two ends, in order to brake said shaft. At the same time, the supporting housing itself is rotated about the axis of the shaft (6) in order to steer the car in the desired direction. <IMAGE>

Title: Device for withdrawing a multi-pin electrical component from a plug base
Inventor: STOHR EDUARD DIPL ING
IPC: H05K13/04
Filed: 1982-04-21
Abstract: The device according to the invention has two gripping arms (1) which move relative to one another at right angles to the withdrawal direction and engage with gripping fingers (1a) behind a component (11) which is to be withdrawn. The gripping arms (1) are rigidly coupled to a drawbar (2) in the withdrawal direction and hence can be raised by displacing the drawbar (2) in the withdrawal direction. The drawbar (2) is in turn connected to a lever (4) which is supported in a housing (3) of the device such that it can rotate. Each gripping arm (1) is provided at its end opposite the gripping finger (1a) with an oblique surface for an expanding body (5). The expanding body (5) is constructed as a sphere that is connected to an operating rod which can be displaced parallel to the drawbar (2). Thus, by displacing the operating rod (2), the gripping fingers can be opened and the device can be placed onto the component (11) to be withdrawn. Fitted on the housing (3) are supporting limbs (10) which rest on the longitudinal sides of the component to be withdrawn during the withdrawing process, and support the housing (3) on the plug base (12). During withdrawal, the gripping fingers (1a) engage on the lateral sides of the component (11). Thus even components which are very firmly seated in a plug base can be withdrawn with little force being exerted. <IMAGE>

Title: Device for checking the electrolyte filling level in an accumulator battery
Inventor: LEDJEFF KONSTANTIN DIPL PHYS D
IPC: H01M50/569
Filed: 1982-09-09
Abstract: The cells (1-5) of an accumulator battery (6) whose electrolyte is circulated by means of gas-operated blower pumps can be checked for the adequacy of the electrolyte filling level in that the gas flow from the compressed gas source (10) to the pumps (8) is diverted by means of three-way valves (11,12) through the bypass line (13) and the gas pressure is reduced by means of the reducing valve (14) to such an extent that it does not quite overcome the hydrostatic pressure of the liquid column at the minimum permissible filling level (e.g. in cell 3). If the liquid column is shorter, a gas flow occurs which the detector (15) registers and indicates as an "electrolyte fault". <IMAGE>

IPC: B23Q7/04
Filed: 1983-08-17
Abstract: A workpiece changer which has two pairs of grippers serves to change the workpieces of a two-spindle lathe. This workpiece changer fetches unmachined parts from a magazine and exchanges them for the finished parts. The magazine contains seven unmachined parts. So that a drawer can nonetheless be completely emptied and filled with finished parts before the next drawer is used, the workpiece changer, after receiving the last pair of unmachined parts from a drawer, grips an unmachined part and a finished part with its two free grippers and deposits these parts in an intermediate deposit place. When the next drawer is approached, the workpiece changer fetches these different parts from the intermediate deposit place and deposits them in the next drawer after two unmachined parts have been removed beforehand. The method according to the invention enables drawers of a magazine which have an uneven number of deposit places to be filled completely with finished parts one after the other by means of a single workpiece changer after the unmachined parts have been removed beforehand in each case.
