Patent EP-0066754-A1 (EP)
Inventor: SAIRANEN MARTTI
IPC: H05B41/292
Filed: 1982-05-21
Abstract: An electronic mains connection device for a gas-discharge lamp, acting as a stabilizing current limiting element and comprising an inverter circuit which from rectified mains current or from some other direct current converts the service voltage for a lamp to such a high frequency that the impedance of a discharge lamp is like normal resistance. A problem is to provice a stable current limitation without current limiting impedances, whereby the limitation of a current can be arranged to be effected only by means of the lamp's own resistance-like impedance on both half-cycles. For this end, the limitation of a current is effected during a period longer than a cycle of inverter operation by means of a feed-back control (7, 8) of the lamp current, controlling the opening times and/or operating frequency of the switches (3, 5) of said inverter circuit.

Abstract: A logic signal analyzer comprises a time measuring adapter. Only some of the input channels of the signal analyzer are used to store input data when an event occurs, i. e. when one or more of the binary input signals change their value. A time counter (7) is provided for measuring the time that has elapsed between two consecutive events. The contents of the time counter are transferred to the logic analyzer on the remaining input channels. 
     In another mode of operation only the signal on a predetermined input channel is used to control the storing operation. The time counter is reset after each storing operation. 
     In still another mode of operation the signal on a predetermined channel can be used to inhibit or allow the storing of the signals on the remaining input channels.

Abstract: Conventional methods of waste processing such as burying, incinerating or fermentating waste are typically costly, polluting and unhealthy. Waste matter may be processed by sterilising and compressing it into a solid block. The block may be stored in a hermetically sealed case (6). This method can be effectively performed safely and cleanly in a factory at low cost. The resulting garbage cases can be used in road foundations, making embankments and slopes, filling holes in the ground or in building dams.
