Title: Roller-blind casing and process for the production thereof
Inventor: BACHL KARL
IPC: E06B9/17
Filed: 1981-07-29
Abstract: A roller-blind casing with a shell (1) having a width (b) corresponding to the nominal thickness of the masonry work and consisting, in particular, of lightweight concrete, encloses an insert body consisting of heat-insulating material (6), such as foam, in one piece. The heat-insulating material (6) leaves free a cavity (7) which serves to receive the roller-blind apron (9), rolled up on a shaft (8), and the vertical centre line (14) of which is offset, in the direction of the outer wall (2) of the shell (1), with respect to the vertical centre line (15) of the shell (1) by a dimension (x) which corresponds at least to half the thickness (d) of the heat-insulating material (6) in the region of the inner wall (4) of the shell (1). As a result, optimum heat insulation is obtained between the cold cavity (7) and the room side of the shell (1). The lightweight concrete of the shell (1) is introduced homogenously into the masonry work and, owing to its design in one piece, provides a good underlying surface for plaster, wallpaper, etc. on the room-side inner wall (4) and the adjoining room-side bottom wall (18). The mounting opening (16) for gaining access to the cavity (7) can be located on the outer side of the window (13) without sacrificing the window-seal width. <IMAGE>

Title: Electrophotographic recording material and process for its production
Inventor: LUTZ MANFRED DR RER NAT
IPC: G03G5/082
Filed: 1982-03-01
Abstract: The electrophotographic recording material comprising an electrically conductive backing and a crystalline inorganic photoconductor layer of a II-VI compound semiconductor applied to the backing by cathode sputtering without the action of a bias voltage on the anode side, has a trap concentration of the photoconductor of more than 1x10<16> cm<-3>, to reduce charge transport. High charging voltages at small photoconductor layer thicknesses above 1  mu m are achieved with this photoconductor material. The layer thicknesses which are smaller than those of known photoconductor layers based on selenium make better resolution possible. Because of greater layer thicknesses and higher charging voltages than with known crystalline photoconductors, these can also be used in rapid electrophotographic apparatuses.

Title: Device for power switching in the case of electrical cooking plates
Inventor: SCHEMBERA FRIEDRICH
IPC: H05B3/68
Filed: 1982-03-18
Abstract: A device for power switching in the case of electrical cooking plates, having a heater consisting of a single heating conductor circuit and having a multi-stage contact switch, which is constructed as a seven-position switch and can be set, via a switching shaft which is provided with a rotating knob, to various switch positions and hence to different power stages for the cooking plate. This device is improved such that, by pulling the rotating knob in the lower switch stages I to III for a defined time duration a higher heating-up power can be set for the cooking plate, which power is significantly less than the full cooking plate power. Once this time period has elapsed, the cooking plate is heated again, without manual involvement, at a continuous cooking power corresponding to switch stages I to III, which is reduced in comparison with the heating-up power.

Patent DE-3222880-A1 (DE)
Title: Method and arrangement for producing a pipeline in underground driving
IPC: E21D9/00
Filed: 1982-06-18
Abstract: When producing a pipeline in pipe advance operation between a starting shaft (A) and a target shaft (Z) with excavation and conveyance of the cuttings, a steel driving pipe (6) serves only as provisional lining for the underground pipes during the construction state, and with the recovery of its parts after completion of the driving is replaced by a final lining (22), e.g. of concrete pipes. This ensures that the devices required for both the construction state and the final state are used only for the respective state and can therefore be optimally adapted to their requirements. The supply lines are firmly integrated in the individual parts of the driving pipe (6) and can be connected by fitting one inside the other so that the necessary line connections can be made simply by fitting the parts together. <IMAGE>

Title: Safety heel hold-down for a cross-country ski
Inventor: STRICKER HERBERT
IPC: A63C9/20
Filed: 1982-07-21
Abstract: For the purpose of developing for a cross-country ski a simple safety heel hold-down which is easily adjustable in the strength of release and guarantees a free vertical mobility of the ski boot heel without active actuation by the skier during cross-country skiing and a lateral transverse fastening during downhill skiing in such a way that, in the safety case, the heel is released when a dangerous load transversely to the running direction is reached, a known safety heel hold-down for a cross-country ski has been further developed. The improvement consists in the fact that the heel hold-down limits the movement of the skier solely laterally, that a catch is provided between the heel hold-down and the holding plate, and that the frictional engagement of the catch with the prestress of the spring is adjustable. For cross-country skiing with such a safety heel hold-down as part of the ski binding it is only necessary to provide a lateral restriction of movement without "locking" the boot heel to the ski and to construct this lateral fastening by providing a catch between the heel hold-down and the holding plate by means of a spring which is adjustable in the strength of release in such a way that lateral rotation of the heel hold-down on the holding plate is possible in the case of dangerous transverse loading.

Patent DE-3230236-A1 (DE)
Title: Darlington circuit
Inventor: BRAJDER ANTONIO
IPC: H03K17/615
Filed: 1982-08-13
Abstract: In a Darlington circuit comprising a pre-driver transistor (T1), a driver transistor (T2) and a power transistor (T3), the collector of the pre-driver transistor (T1) and the collector of the driver transistor (T2) are connected via a diode (D), the cathode of which faces the collector of the pre-driver transistor (T1). This diode (D) blocks the pre-driver transistor (T1) against a power transistor (T3) in the region of low collector currents (ic) so that the circuit now only acts as a two-stage Darlington circuit. This reduces the voltage drop across the power transistor (T3) in the region of the low collector currents (ic). In the region of high collector currents (ic), the voltage drop across the power transistor (T3) is increased by the forward voltage of the diode (D). However, when the power transistor (T3) is operated only for a short time in the region of high collector currents (ic), the power dissipation of the power transistor (T3) is reduced overall and thus its load carrying capability is increased. <IMAGE>
