Title: VTR with low power consumption
Inventor: AMANN ULRICH
IPC: H04N5/63
Filed: 1993-01-30
Abstract: The video recorder has a signal input connection and an output connection for a TV receiver. The VTR is switchable between normal operation and a standby state. In a third state, only the transmission circuit and a time control unit are activated. The VTR is returned to normal operation manually or by a time controlled switch.The time control is also used to record programmes at specific times. At specific times, e.g. 00:00 every day, the processor for recording is activated. The VTR is switched from the third state to the normal operation state when a video programme storage programme is detected for the required day.

Patent DE-4310484-A1 (DE)
Inventor: ROTH MANFRED
IPC: F24D3/14
Filed: 1993-03-31
Abstract: Underfloor heating system for floors, having an insulating layer made of expanded polystyrene insulating boards, heating pipes made of plastic which are laid on the insulating layer, and U-holders made of plastic for the heating pipes. The underfloor heating system is laid upon the floor, the U-holders engaging over the heating pipes with their web and being pushed into the insulating layer with their legs and also anchored in the insulating layer by barb elements. A floating floor screed is applied to the insulating layer with the laid heating pipes. The expanded polystyrene insulating layer consists of a bottom layer with a low specific gravity and a top layer with a high specific gravity. Both layers belong jointly to a monolithic insulating-board unit. The legs of the U-holders possess barb elements which are arranged in the shape of a V in the pushing-in direction, are elastically deformable towards the assigned leg and can be spread apart under the influence of tensile forces acting on the U-holders. In the pushed-in state, the barb elements are situated in the bottom layer of the insulating-board units. The top layer of the insulating-board units is tread-resistant due to its layer thickness. Due to their board thickness, the insulating-board units comply as a whole with the requirements according to DIN 4109. <IMAGE>

Abstract: An arrangement of a power component (10) on a printed circuit board (11) consists of a physical unit (12) which can be preinstalled and consists of the power component (10), a holder (13) and an electrical insulating layer (14) which is applied to the side facing the printed circuit board (11). Ceramic or plastic, for example, is used for the layer (14) in order to make electrical installation possible. The holder (13), in contrast, consists of a high thermally conductive material, for example metal, in order to obtain good heat dissipation from the power component (10) to the printed circuit board (11) and thus to a heat sink. The assembly (12) is fitted to the printed circuit board (11) using the so-called reflow soldering procedure. This arrangement can be used very cost-effectively and in the assembly method which was used in the past. <IMAGE>

Title: Method for guiding air in a receiving chamber and apparatus for working small parts
Inventor: BERTSCHE THOMAS
IPC: F24F3/16
Filed: 1993-12-24
Abstract: In a method for guiding air in a receiving chamber having an especially rectangular area for treatment articles, the air is guided from above onto the area and carried away and also deflected to the edge regions above the area of the receiving chamber which is tightly closed to the environment. At the edge regions, the air is led away uniformly over the entire length of the area through conduction spaces bounded by said edge regions, resulting in a laminar flow of the air. The apparatus for working small parts is provided with an area (24) which is supplied with air from above from a flow space and is tightly surrounded by a double-walled housing (12) under clean-room conditions; said housing forms at the edges of the area continuous flow passages (54). Arranged in front of the housing wall (13, 14) is a separating plate (59) which bounds with said housing wall the flow passage (54) and forms in the housing interior (11) a deflecting edge (60) at a gap distance (t) from the area (24). <IMAGE>

Patent DE-4402494-A1 (DE)
Title: Solar motor
Inventor: SCHAPER RUDOLF
IPC: F03G6/00
Filed: 1994-01-28
Abstract: In order to use solar energy, so-called solar motors, inter alia, were developed in which use was made of a heat engine working in accordance with the STIRLING reciprocating piston principle and mounted at the focal point of a spherical concave mirror (collector mirror). Despite the 42% efficiency of the Stirling motor, the system achieved only a total efficiency of approximately 17%, principally because of the heat losses at the receiver and the relatively slight concentrator efficiency (system from Schlaich & Partner). The present invention uses a heat engine invented by the applicant which owing to its relatively simple mode of operation can be built in a very elongated fashion without a high outlay on cost, with the result that by comparison with previous solar motors the receiver surface is relatively large owing to the use of a spherical concave mirror (higher concentrator efficiency than in the case of the concave mirror), and so a better total efficiency can be achieved. In the case of the use of high-temperature waste heat from exhaust gases or the like for the purpose of heating the receiver of the heat engine, this invention likewise provides a larger receiver surface.

Title: Adjustment of the original wort or alcohol content of beers
Inventor: KOUKOL ROBERT
IPC: C12G3/08
Filed: 1994-02-18
Abstract: The beer, supplied as unfiltered matter to a series of filters, is taken off as a filtrate. Before or after flowing through the filters, the latter are flushed through with filtered material from a pre-/after run fluid. This fluid and/or the filtrate is stored and used to form a mixt., in a quantity which depends on the original wort and/or the alcohol content of the mixture. This value is measured before the series of filters. The same measurement is taken from the fluid at the end of the filter series. A sensor based on sound velocity measurement is used for this purpose. The appts. to perform this process, and a further homogenisation process are also claimed. Use - To adjust the original wort or alcohol content of beer by recycling a mixt. of unfiltered and pre-/after run fluid and/or filtrate, before filtration. Advantage - The method of adjustment reduces the effluent from the process, and saves energy, as no additional heating is required. Raw materials costs are also reduced. The addition is made continuously, and there is an effective capacity increase, as a result of storage of the pre-/after run fluid.
