Title: Condenser for the water/steam circuit of power station installations
Inventor: GROSS RUDOLF
IPC: F28B1/02
Filed: 1987-09-28
Abstract: Condensers in power stations having a boiling water reactor as steam generator normally have condensate feed paths to condensate delay (hold-up, holding) vessels (16) and, correspondingly, two respectively inherently controllable groups of cooling tube bundles (bunches) (2) and measuring probes (21) for monitoring the electric conductivity of the condensate. According to the invention, each feed path of the condensate is assigned its own condensate delay vessel (16), and provision is made above each condensate delay vessel (16) of an inclined drain plate (9) which has on its lower edge an upwardly bent deflecting web (12) via which the condensate drains into the associated condensate delay vessel (16), and there are arranged at the bottom of a retaining chamber (11) formed by the drain plate (9) and the deflecting web (12) at least in each case one measuring probe (13) and the opening of a drain line which is closed in normal operation. The retaining chamber (11) has at most 0.1 times the volume of the associated condensate delay vessel (16). Owing to the low volume of the retaining chamber (11), possible contaminations in the condensate are detected very quickly, with the result that it is possible to drain the contaminated condensate via the drain line (14) before the condensate contained in the condensate delay vessel (16) or the condensate already resupplied to the circuit becomes contaminated. It is particularly advantageous to use the condenser according to the invention in nuclear power stations having ... Original abstract incomplete. <IMAGE>
Patent DE-3732852-A1 (DE)
Title: Method and arrangement for the Boolean classification of measured value amounts
Inventor: MINCK KONRAD
IPC: G01D1/14
Filed: 1987-09-29
Abstract: A respective measured value amount, determined by a measured-value transmitter, is compared with a minimum value and the upper limit value of the measuring range. In the case of under- or overshooting of a threshold value between the minimum value and upper limit value, the measured value amount is assigned to the minimum value or to the upper limit value. In the case of assignment to the minimum value, a correction contributing to reducing the difference between the measured value amount and the minimum value is made to the minimum value in two stages. Only in the event of over- or undershooting of a primary correction stage is the minimum value stored in a correction main stage raised or lowered. In the case of assignment to the upper limit value, a correction contributing to reducing the difference between the measured value amount and the upper limit value is made to the measuring sensitivity, likewise in two stages. <IMAGE>

Title: Electric foot-sole heating system
Inventor: IMMENDORF KARL M DIPL ING
IPC: A43B3/35
Filed: 1987-12-14
Abstract: The structure of an electric surface-heating system for cold-sensitive parts of the body - in particular for foot soles - is defined by three criteria for obtaining optimum efficiency:   1. The design of the heating sole which contains the main heating surface in the region of the toes and which rests directly on the foot sole, optimally insulated against the cold environment. 2. The primary/secondary batteries or accumulators serving for power supply are, using the body heat of the user, kept at a temperature at which the optimum capacity of the batteries/accumulators is ensured. 3. The electronic control necessary for heating control has minimum inherent losses.   With consistent observation of the criteria listed above, it is possible to make a foot-sole heating system for people exposed to the cold, e.g. skiers, market women, which produces pleasantly warm feet over a number of hours even at minus 10 degrees, with minimum inconvenience due to weight and space factors.

Title: Saddle bridge for attaching to spectacles
Inventor: WINKLER ROLF
IPC: G02C5/12
Filed: 1988-06-15
Abstract: A saddle bridge for attaching to spectacles consists of a basic element comprising a U-shaped sheet-metal part (20) whose bridge region (21) is connected to the spectacles and is essentially surrounded completely by a coat (30) of soft, skin-friendly and non-slip plastic so that the legs (22, 23) of the sheet-metal part (20) can be continuously adjusted independently of the contour of the edge of the spectacle lens. In this case, the legs (22, 23) of the sheet-metal part (20) have recesses or passages (22A, 23A) and the plastic of the coat (30) has a Shore-A hardness of between 30 and 70.   This solution has the advantage that production can take place very cost-effectively on an industrial scale, since due to the flexibility and usability (suitability) both for plastic and metal spectacles the entire spectrum of spectacle forms which occur in practice can be covered by one or a maximum of two differently sized saddle bridges (Figure 1). <IMAGE>

Title: System for the installation of electrical devices to be arranged in series (rows)
Inventor: GRABOWSKI WALTER
IPC: H02G3/08
Filed: 1988-10-08
Abstract: In the case of installation systems which can be designed individually from installation boxes (junction boxes) (11) which can be strung together, the problem arises of individually occupying the installation boxes (11), combined to form the installation system, with conductors or conductor sections to reflect the respective necessity. For this purpose, the installation boxes are provided with channels (122, 122' ... 122<VII>) which project from the bottom into the interior of the box, extend between the regions (112, 113), provided with flush passages, of the outer surface of the box, and run parallel to each other, into which the conductor sections which are accessible to connections from the inside of the box can be inserted in a shock-hazard-protected manner (such that it is protected from being touched). This opens up the possibility of forming the installation system from one basic element, that is to say one standard installation box (11), it being possible to fit the respective installation box (11) in each case individually with conductor sections. <IMAGE>

Title: Icing protection for an evaporator of an air-conditioning installation
Inventor: PETRI HORST DIPL ING
IPC: B60H1/32
Filed: 1988-10-31
Abstract: In particular in motor vehicles the evaporator of an air-conditioning installation is passed through by an air flow which is generated at least by a variable-speed electromotively driven fan. In order to prevent icing of the evaporator, the temperature of the evaporator is detected in the region of the coolant-bearing lines which run outermost in the evaporator by means of a temperature sensor and the measured temperature value is, in a comparative arrangement, compared with an icing temperature value which is dependent on the flow speed of the air. If the temperature falls below this icing value, the air-conditioning installation is switched off.

Title: Process for preparing silicon tetrafluoride
Inventor: DOETZER RICHARD DIPL CHEM DR
IPC: C01G43/00
Filed: 1988-12-07
Abstract: A process is provided in which silicon tetrafluoride is produced at a temperature of about 60@ or above by reaction of dry silicon dioxide with preferably depleted uranium hexafluoride in the presence of a strong mineral acid, preferably concentrated sulphuric acid. The process gives a pure product which is exceptionally low-cost owing to the cheap starting materials and is suitable for further processing into solar cell silicon. The final uranium product formed is the solid uranyl sulphate which is chemically stable and therefore easy to store. This achieves a further cost advantage compared with the high-cost storage of the aggressive uranium hexafluoride and decreases the "disposal problem" for the depleted uranium. <IMAGE>

Title: Reversing valve which can be used as a resetting valve
Inventor: VOSS RICHARD
IPC: E21D23/16
Filed: 1988-12-09
Abstract: A resetting valve intended for underground mining works continuously and quickly and has exceptionally favourable overall dimensions. A valve sealing on two sides and serving as reversing valve and, following the piston area, an adjustable pressure-relief valve are allocated to the pump connection. The tightness of this resetting valve and the passing of the pressure medium through the resetting valve are substantially improved by the sectional pistons and the piston of the pressure-relief valve and the control piston being designed to yield to a limited extent in the area of the sealing faces corresponding with the respective valve seat. The resetting valve can be used for HFA and HFC pressure fluids as well as for HFD pressure fluids without there being any sealing problems or too short a service life. Control piston and sectional piston of a shuttle valve are connected via a push rod. When the prop pressure is admitted to the control piston, the pressure medium, even water, can flow into the pusher-ram connection. The pusher-ram connection is in turn connected to a pressure-relief valve. <IMAGE>

Inventor: WALDMANN JUERGEN DR
IPC: G02F1/137
Filed: 1988-12-24
Abstract: A black/white liquid crystal display (10) contains a nematic liquid crystal having a twist of 270 DEG  between two cell plates. The product of the liquid crystal layer thickness and the anisotropy of the refractive index is approximately 0.38. A pretilt of approximately 15 DEG is present. The polarisation directions (P1, P2) are at an angle  beta  of 45 DEG  to the orientation directions (Mo, Mu). 
<??>Over a very large range of viewing angle, this display has a relatively low dependence on the contrast of the viewing angle, and there is practically no colour displacement at all that depends on the viewing angle. Because of the considerable improvements, when compared with all known cells, in the range of the viewing angle with respect to contrast and colour neutrality, the display is termed an "extended-viewing-angle" display (EVA display). It can be multiplexed to a very high degree.
