Title: Appliance for changing money in an amusement arcade having coin-operated entertainment machines
IPC: G07F17/32
Filed: 1989-01-25
Abstract: In known appliances for changing money in an amusement arcade, it is necessary that the appliance for accepting banknotes and dispensing coinage be part of a multiple stand for receiving coin-operated entertainment machines. Coin channels lead from the entertainment machines to a safe of the money-changing appliance. Technical faults in the coin-dispensing device of the money-changing appliance or an insufficient stock of change cause the appliance to be put out of operation. With the new appliance, a money-changing operation is always to be guaranteed. For this purpose, the appliance comprises a centrally arranged housing with a banknote-acceptance station and with a central control device, from which, depending on the banknote to be changed and allowing for the coin stock in the dispensing devices, the stand activates the coin-dispensing device from the central control device for the purpose of paying out coins.

Title: Cheese grater
Inventor: WOERWAG PETER
IPC: A47J43/25
Filed: 1989-02-08
Abstract: The invention relates to a grating device, which can be driven by motor, is to be gripped with one hand and is of small dimensions, for grating pieces of cheese which are received by a storage shaft and are pressed against the rotationally driven grating drum by a pressure plate attached to the lid part of the storage shaft and reaching into the interior of the storage shaft. The grated cheese drops out of the discharge opening from the inner space of the grating drum. In the event of failure of the drive unit, the cheese grater can be operated by hand. Further grating and grinding devices with identical connections can be interchanged for the cheese grater.

Title: Arc extinguishing arrangement for a short-circuit-current limiting low-voltage switch (circuit breaker)
Inventor: WALTHER OTTO
IPC: H01H33/76
Filed: 1989-02-13
Abstract: The arc extinguishing arrangement for a short-circuit-current limiting low-voltage switch has a housing (1), two contact pieces (2, 3) which can be engaged with one another and disengaged from one another in the housing (1), and an insulating wall (4) which can be displaced between the separated contact pieces (2, 3). The insulating wall (4) is equipped with an opening (5) which is provided for the contact pieces (2, 3), which are engaged with one another, to pass through. Between the closed contact pieces (2, 3) and the walls of the housing (1) and the opening (5) surrounding them there is only a gas area which is less than half the contact displaced volume. The insulating wall (4) is provided with thickened regions (6, 7) in the edge region of the opening (5) which lies in the movement direction of the insulating wall (4) when an arc is being extinguished. The thickened regions (6, 7) are guided tightly in additional grooves (8, 9). The additional grooves (8, 9) have a constant cross-section of 20 to 100 times the volume of the contact displaced volume. The additional grooves (8, 9) are connected, by the gas, to a blowing-out area after the section having a constant cross-section. The insulating wall (4) is driven only by the gases produced in the arc. <IMAGE>

Inventor: THOENY CHRISTIAN-ERIK
IPC: G01D5/14
Filed: 1989-08-09
Abstract: A device for measuring lengths, angles and the like comprises two components which can move relative to each other and which together form a magnetic circuit. One component comprises a sequence of alternating ridges of relatively high and relatively low magnetic conductivity, spaced at a predetermined interval apart in the direction of relative movement. The other component comprises at least one measuring element with a sensor which responds to fluctuations induced by the relative movement of the two components inthe magnetic flux produced by a magnetic flux source and guided by the magnetic circuit. In the measuring element, several partial, adjacent magnetic fluxes aligned in the direction of the mutual movement of the two components and separated in function of the spacing between the ridges jointly form a total flux and the at least one sensor is arranged and/or designed so that it emits an output signal which is a function of the sum of the partial magnetic fluxes.

Title: Vibration control for transmission in vehicle - has ignition timing correction to suppress uneven running
Inventor: BURCKHARDT CHRISTOPH
IPC: F02P5/15
Filed: 1990-03-27
Abstract: The engine speed is monitored to determine rates of change of speed i.e. vibrations and their values used to correct the ignition timing. The amount of correction is determined by a programmed control and is in proportion to the degree of vibration. The vibration correction is rapid and does not depend on the inertia of the engine/fuel system. The engine speed is monitored by impulse generators and with counters to count the impulses over set segments of the rotation. Simple comparators derive the count difference and use it to generate the correction factor for the ignition timing. A freely programmed microprocessor computes the correction factor. ADVANTAGE - Simple control, rapid response vibration control.

Abstract: A connecting element is described for the detachable connection of two rack components, especially a supporting profile and an edge profile, the connecting element being arranged in a fixed position in the edge profile, which is constructed as a hollow profile, and having at least one moving retaining element in a housing, with which the connecting element, and hence also the edge profile, can be connected detachably to the supporting profile and there being arranged in the housing, supported such that it can rotate, an eccentric bolt by means of which the retaining element is guided such that it can move longitudinally in the housing, as a result of which a component of the retaining element, projecting from the end face of the housing, can be brought into engagement with an undercut longitudinal groove in the supporting profile, and the eccentric head of the eccentric bolt, which can be pressed into the housing against the force of a spring, being latchable into a hole in the edge profile, and having a safety device preventing the eccentric bolt from being able to move axially when the retaining element is in the pushed-in position. In order to provide a hindrance to pushing in, by means of which it is ensured that it is not possible for the retaining element to spring inadvertently out of the eccentric disc, it is provided that the safety device consist of at least one cam, constructed on the moving retaining element, and at least one recess, constructed in the housing base, the cam and the recess being arranged and dimensioned with respect to one another in such a manner that the cam comes to rest opposite the recess in the housing base in the withdrawn position of the retaining element and at the same time permits axial mobility of the eccentric bolt, but in the pushed-in position of the retaining element is not engaged with the recess and is supported on the housing base, and axial mobility of the eccentric bolt is hence prevented. <IMAGE>
