Title: Method to produce identity cards with photograph
Inventor: LAEMMERMANN SIEGFRIED
IPC: B42D25/00
Filed: 1982-09-13
Abstract: A method to produce identity cards with photograph, wherein picture information and, if appropriate, written information are transferred from a document onto a coated thin plastic film which is then placed between a transparent covering layer and a basic layer, which is thick compared to the plastic film, both layers being made of plastic, and is welded to these layers over the surface. In a known method, the information from the document is transferred to a plastic film coated with a photosensitive material by optical means. The apparatus to carry out this method is technically complicated and expensive. The underlying object of the invention is to provide a simple and inexpensive method, with which non-forgeable identity cards with photograph can be produced. The object is achieved according to the invention in that the coating of the plastic film is undertaken by applying a coloured layer, and in that the information is transferred using an engraving device by scanning the document with an electrooptical receiver and engraving it into the coloured layer. <IMAGE>

Abstract: Power MOSFETs for switching high voltages have a relatively high on-state DC resistance. The invention provides for the connection in series of a low voltage MOSFET with a higher voltage bipolar transistor. This series circuit is connected in parallel with a series circuit consisting of another MOSFET and a threshold switch. The threshold switch is placed between the base terminal and the free terminal of the low voltage MOSFET. The MOSFETs receive a joint control signal (u1) which is routed to the low voltage MOSFET. In the case of an inductive load with recovery operation, the signal is routed through a delay element that becomes active when the circuit is turned on.

Abstract: An extruder is controlled in response to the thickness measurement of the extruded strand. The thickness measuring head is initially given a displacement transverse to the extrusion direction, preferably around the extruded strand and the output signals from the head are integrated to form a mean value around the periphery. A comparison of this mean value with the set point wall thickness value is then utilized to provide continuous correction of the output of the head which is utilized to regulate the extruder operation.

Title: Circuit arrangement for controlling the brightness of fluorescent lamps
Inventor: ZAPP ROBERT
IPC: H05B41/392
Filed: 1983-05-13
Abstract: In order to be able to control the brightness of even fluorescent lamps with an increased starting voltage (for example lamps with a diameter of 26 mm) without flickering using a normal dimmer circuit, the additional arrangement of a radio-frequency generator (7) is proposed, which generator has the mains AC voltage applied to it on the input side via the dimmer (5) and, on the output side, emits a radio-frequency AC voltage to the electrodes (4a, b; 15a, b) of the fluorescent lamps (1, 12). The amplitude of the radio-frequency AC voltage depends on the internal impedance of the gas-discharge paths of the fluorescent lamps and hence on the switching state of the controllable semiconductor component of the dimmer (5). The radio-frequency generator (7) in this case consists of the series circuit of a switching-on delay element (8) on the input side, a frequency converter (9), a transformer (10), and coupling capacitors (11, 16) on the output side. <IMAGE>

Patent DE-3409330-A1 (DE)
Inventor: RIEDER JOACHIM
IPC: H03F3/30
Filed: 1984-03-14
Abstract: The principles of "linear amplifier circuits for direct current and alternating current" have been known for a long time and are partly derived from the valve techniques. The type which is most commonly used at present comprises a differential input and a final push-pull stage and operates with a counter-coupling. The final transistors operate usually as emitter-followers at the dynamic operation point A-B. This principle requires that the voltage amplifier reaches the voltage amplitude of the output voltage. In the new "linear amplifier circuit for direct current and alternating current", the final transistors (T3, T4) operate as a common emitter at the dynamic operation point B-C and the currents thereof are coupled. The voltage amplitude of the voltage amplifier (OP) has no importance since said voltage allows only the flow of a current to zero. Said current, however, flows from the positive or negative side in the voltage amplifier (OP) and simultaneously controls the final transistors (T3, T4). In case of a small signal or without the latter, the output voltage (U-aus) is generated by two pretransistors (T1, T2). These also operate as a common emitter and their currents are also coupled. The output voltage is obtained from the difference of the collector currents of the push-pull transistors (T1, T2, T3, T4). Said voltage is counter-coupled to the differential input amplifier (OP) and is thus adjusted at a fixed ratio to the input voltage. As the voltage amplitude is smaller at the output (U-aus) of the voltage amplifier (OP) than the input voltage, its open loop amplifier is exclusively used to compensate for the non-linearities of the amplifier. Even the output load has no influence on the output voltage. As the voltage amplitude of the voltage amplifier is only a few volts, the voltage amplifier may be a conventional operational amplifier which is commercially available, even in the case where the output voltage of the final stage is high. Due to the dynamic operation point B-C of the final transistors (T3, T4), the ratio between the output power and the dissipated power is very advantageous, of the order of 3/1. This new principle enables the construction of better linear amplifiers with a reduced number of component parts.
