Abstract: The invention relates to a control means for a transistor switch circuit controlling a power supply circuit for providing electric power to a load, comprising: a power supply stage having a transistor bridge circuit and an LC circuit with an inductor and filter capacitors, and a control stage. The control stage comprises a monitor circuit for monitoring a bridge voltage of a connection between two semiconductor members and the current through the inductor, said monitor circuit comprising a first comparator for comparing when the current through the inductor exceeds a reference value and a second comparator for comparing when the bridge voltage changes polarity towards the corresponding rail polarity; and a drive circuit adapted to provide a firing pulse to one of said switchable members of said semiconductor members for initiating the conduction thereof. The control drive circuit is adapted to terminate the conduction of said switchable member when said first comparator determines that the current through the inductor exceeds said reference value, and to provide another firing pulse when said second comparator determines that the bridge voltage changes polarity towards the corresponding rail polarity. According to the invention, a logic circuit is incorporated in the monitor circuit and connected to the outputs of first and second comparators, said logic circuit being adapted to respond to the first firing edge of a signal from the second comparator only, when the signal from the first comparator permits firing.

Abstract: A method and arrangement for limiting the number of simultaneous users of a software ( 106 ) protected by a licence agreement. A start request is sent from the software to a lock unit ( 108 ) when the software is activated by a workstation ( 102 ), after which it is investigated whether any physical licence unit ( 110 ), connected to the lock unit and corresponding to the software, has a free user position. The software is started if there is a free user position, but is terminated if there is free user position. The solution provides for increased control and security that the number of simultaneous users cannot exceed what is covered by the licence agreement, as well as a simple upgrading of licence agreements.

Abstract: The invention relates to an overload protection for a filmstrip projector. A commonly occurring problem with such projectors is that faults in the picture-changing process, for example that a picture sticks, mean that the picture-changing motor 10 continues to work and thereby runs the risk of overheating. The invention intends to solve this problem, this being carried out by a device 26, 28 arranged on a shaft 24 driven by the motor 10 continuing an electronic time circuit, for example an RC circuit 38, 40 synchronized with the commencement of the picture change. When the picture change has been completed, the time circuit returns to its initial state. However, if the picture change should not work normally, after a certain predetermined period of time, which exceeds the time of a normally operating picture change, the time circuit will control a transistor switch 48 which thereupon breaks the motor current by switching off a relay 18. <IMAGE>

Abstract: The device has electrodes, and comprises a D.C. set (1,2) providing a voltage which is higher than that normally required for operating the filter, and charging a capacitor (Cu). A circuit is connected to the capacitor and the electrodes to form an oscillating circuit. This circuit also contains a control which closes and breaks it with a duration longer than that for oscillation, which has a closing interval covering one or a number of circuit oscillation periods. - The capacitive (Cu) stores energy for ultimate transmission to the filter, and the current control (TD), after closing the oscillation circuit, maintains it thus for a whole number of periods, so that energy oscillates between the condenser and the filter.

Abstract: A method of producing platens for typewriters and similar office equipment. Conventional platens often include a large number of individual parts and are relatively expensive because of their high assembly and finishing costs. According to the invention, an impact-resistant polyolefin with the addition of a delayed-reacting foaming agent is employed in an injection molding process in such a fashion that, by means of differential cooling of the mold, the material on the platen surface and in areas of other functional elements such as line-advance wheel/notched wheel combinations hardens, while the core of the platen remains a foam. The process allows platens with other functional elements molded to them to be manufactured from a single material in a single operation and without any additional work, despite different demands made on the print backing and the other functional elements.
