Patent DE-3804248-A1 (DE)
Title: Process for removing impurities from a silicon melt by directed solidification
Inventor: SCHULZE FRIEDRICH-W DR RER NAT
IPC: C01B33/037
Filed: 1988-02-11
Abstract: In a process for removing impurities from a silicon melt by directed solidification (4), the silicon melt is brought to solidification only to such an extent that the impurities collect in a residual melt (3). Calcium or calcium oxide is then added to this residual melt (3) and the solidification (4) is continued. After complete solidification, there results a silicon block (1) having a "block head" (3) which contains the impurities. The block head (3) is removed mechanically and/or by acid treatment. This separation process is preferable to the otherwise customary sawing process, since the material (3), as a result of the calcium silicide phase separating out at the grain boundaries, is mechanically less stable and therefore cannot be removed without losses and great effort. Silicon crystals present in the block head (3) are again fed to the process. The process is used for the production of silicon for solar cells, in particular subsequent to the carbothermic reduction of SiO2. <IMAGE>

Title: Method and device for controlling the lye pumping-off operation in washing machines
Inventor: ANKELMANN WOLFGANG DIPL ING
IPC: D06F33/47
Filed: 1988-06-28
Abstract: The lye-pump feed capacity must correspond to the quantity of waste water from spinning. In appliances which are on the market, the lye pump is activated via a program-switching unit. The "on" and "off" times of the pump do not run in synchronism with the quantity of waste water from spinning, so that the pump running empty sucks in air and does not discharge the lye. By means of the solution according to the invention, the lye-pump feed capacity is matched exactly to the quantity of waste water occurring. The drive motor (8) of a lye pump (5) possesses a marking or a transmitter on its fan impeller (9). By means of a sensor (12), the rotational speed is entered as an input signal (13) in an electronic unit (14). Desired values filed therein are compared with the input signal (13), namely the actual value, and the lye pump (5) is briefly switched off and on again, as required, via a switching element (11).   The method and device according to the invention are especially suitable for use in domestic washing machines, and also for dishwashers or similar appliances which possess pumps driven by means of synchronous or asynchronous motors. <IMAGE>

Title: Plane-parallel refracting lens, also used as supplementary unit for a display device and method for their production
Inventor: AUGUSTIN HANS-ULRICH
IPC: G02B3/00
Filed: 1988-09-23
Abstract: A plane-parallel refracting lens (1) has structures (2) which are arranged parallel to each other on an optically transparent carrier (substrate). These structures form on the originally level (flat) surface with a single reflection normal an optically transmitting surface, the inclination angle and consequently the reflection normal of the surface always remaining the same in one direction of expansion and only changing, for example periodically, in the direction which is perpendicular thereto. By the form of the structure it is achieved that the reflection normals at all locations of the surface and the original main normal form planes which are parallel to each other. Due to this surface form, it becomes possible to view an object, located under the carrier and having a reflecting surface, also at such angles which would normally lead to a large part of the light beams being reflected from the surface of the object. The structures can be incorporated into the surface of the carrier or the object or applied thereon. A plane-parallel refracting lens makes it possible to read easily, also from the side, surfaces without antireflection coating, for example in display devices. The disadvantage of loss intensity due to an antireflection-coated surface is thus avoided. <IMAGE>

Title: Thermal radiation sensor
Inventor: GRUENWALD WERNER DR DIPL PHYS
IPC: G01J5/24
Filed: 1989-01-14
Abstract: A thermal radiation sensor is proposed, having four sheet-like resistance elements (1-4) arranged in a bridge circuit, of which two are designed as temperature-dependent resistance elements (1, 2) and two as largely temperature-independent resistance elements (3, 4). An insulating substrate wafer (5) carries the four resistance elements (1-4), as well as conductor tracks (6) connecting the latter. A housing (11, 12) accommodating the substrate wafer (5) has a window (13) transparent to thermal radiation in the region of one of the temperature-dependent resistance elements (1) and is provided with contact pins (7-10) led through the housing in an insulated fashion and serving as electric connections for the bridge circuit. These contact pins (7-10) are arranged closely alongside each other in the central region of one housing wall. The housing (11, 12) or at least essential parts of the latter consist of a metal which conducts heat well, preferably aluminium. In this way, by means of the housing conducting heat well, an environment for the substrate wafer (5) is produced which is of uniform temperature and, furthermore, the thermal conduction between the housing and the substrate wafer (5) is minimised and made symmetrical, by which means no interference (noise) signals are generated even in the case of thermal radiation incident from the side. <IMAGE>
