Patent DE-3212195-A1 (DE)
Title: Air-conditioning plant
Inventor: NOMAGUCHI TAMOTSU
IPC: F25B29/00
Filed: 1982-04-01
Abstract: The invention relates to an air-conditioning plant with a refrigerant compressor which is connected to a four-way valve and subsequently, in a kind of room-cooling operation and a first kind of room-heating operation (parallel), to a refrigerating circulation which includes an internal room heat exchanger, an externally heated heat exchanger, a refrigerant duct, a first electromagnetic valve and an external heat exchanger, a second electromagnetic valve being connected in parallel to the external heat exchanger between the refrigerant duct and the four-way valve, in order to form in the second kind of room-heating operation a refrigerating circulation with the internal heat exchanger, the externally heated heat exchanger and the refrigerant duct. In the kind of room-cooling operation and the first kind of room-heating operation, the first electromagnetic valve is open, and the refrigerant duct and the externally heated heat exchanger allow liquid refrigerant to flow back, the sum of their volumes being equal to the volume of the external heat exchanger; on the other hand, the external heat exchanger effects a backflow of the liquid refrigerant in the second kind of room-heating operation, in which the second electromagnetic valve and an electromagnetic valve connected (parallel) via the compressor are open. <IMAGE>

Title: Cleaning cassette with liquid cleaning agent
Inventor: BUSCHER ALFRED
IPC: G11B5/41
Filed: 1982-02-24
Abstract: A customary cleaning cassette was used, which first of all was given a different cleaning tape which was absolutely lint-free. This was made possible by a polyester tape. In order then to bring the cleaning liquid to the magnetic head, in the middle of this cassette an oscillating tank was arranged, which is filled via a valve and takes up cleaning liquid by the suction effect when the roll unwinds and only in this way cleans the magnetic head in a conserving way. Magnetic head cleaning cassette, characterised in that an oscillatingly suspended tank (1) with built-in suction element (felt 2) receives the cleaning liquid and thus passes it on to the magnetic head during running of the polyester tape (3) and consequently cleans the said head. By this method, a reliable and entirely conserving cleaning of the magnetic heads is ensured. <IMAGE>

Patent DE-3218237-A1 (DE)
Title: Transmitting/receiving antenna
Inventor: VOGEL MARTIN DR ING
IPC: H01Q19/06
Filed: 1982-05-14
Abstract: In a lens antenna, the radiation incident from a prescribed sector is focused onto a focal line and this focal line is deflected out of the lens plane by means of a beam deflecting device and projected onto part of an arc of a circle. By rotating one or more primary emitters along this circle, the radiation pattern can be swivelled mechanically in a simple way inside the prescribed sector without the antenna aperture being blocked. The use of a rotationally symmetrical parallel-plate laminated lens is particularly advantageous.

Patent DE-3241782-A1 (DE)
Title: Return duct closure in an inspection chamber
Inventor: BITTNER HANS-PETER
IPC: E03F7/04
Filed: 1982-11-11
Abstract: It is known that, following sudden rainfall, the water level in an inspection chamber can rise, to such an extent that great damage can often be caused in cellars by the deposited water and sludge which enters through the gullies. The return duct closure can however prevent this. The lid normally stands slightly tilted with respect to the water level. If however the water level rises abnormally, the lid is pressed against the duct socket and penetration into the duct tube and back to the cellars is prevented. If the water level drops, the lid returns into its open position. This position is given by means of the notch in the holder articulation. The object is achieved according to the invention in that the duct socket is attached to the wall not vertically, but horizontally by virtue of its conical design, which ensures a safe outflow from the duct tube and prevents a penetration into the duct tube.

Filed: 1983-03-22
Abstract: A method and a device for producing colour pictures from partial pictures, in particular colour pictures with relatively large homogeneous areas, are proposed, which colour pictures are represented by superimposing a plurality of basic colours. The colour gradations in the colour picture are produced by different halftone dot areas by the respective basic colours. For one basic colour in each case, a partial picture is produced which has the halftone dot area corresponding to the basic colour. The position and the shape of the different colour areas of the colour picture to be produced are stipulated and the colour of the respective colour areas are selected. Drawn within the contour of the different colour areas are parallel screen lines whose line width is varied in accordance with the predetermined colour dot area, the screen lines being represented for each basic colour at a different angle to the horizontal plane (Figure 1). <IMAGE>
