Title: Arrangement for equalising amplitude and phase distortions on transmission paths for analog signals
Inventor: BITZER EBERHARD DR ING
IPC: H04B3/14
Filed: 1981-08-13
Abstract: Analog signals undergo amplitude and phase distortions on transmission paths. For automatic adaptive equalisation, an equaliser network with a transverse filter structure (TVF) is set up at the receiving end with transit times @ which are determined by the bandwidth which is to be equalised. The filter coefficients are set with the aid of a digital test signal with a pulse duration  tau which is transmitted from the transmitting end and stored at the receiving end in undistorted form (TEST). The received distorted test signal (d) is compared with the undistorted test signal (W) and an error signal ( <IMAGE> ) generated. The filter coefficients are set with the latter, e.g. on the basis of the stochastic gradient algorithm. <IMAGE>

Title: Tuyere
Inventor: EMONDS FRANZ-JOSEF DR
IPC: C21B7/16
Filed: 1981-08-21
Abstract: Tuyeres for furnaces, in particular for blast furnaces, consist of a tuyere cover with connections for the supply and discharge of the coolant, of a blowpipe connected to the tuyere cover, of two annular sheets, which are arranged concentrically to one another and form a cooling channel, and of a blowpipe tip which seals the sheets at the end and can exhibit an annular cooling channel. For cost reasons and for reasons of handling, it is extremely advantageous if, while maintaining the cooling performance, the weight of the tuyere is substantially reduced while keeping the same dimensions. This is achieved if the tuyere cover and the blowpipe consist of aluminium or an aluminium alloy, if an annular sheet of copper or a copper alloy is plated onto the end of the blowpipe, and if a blowpipe tip consisting of copper or a copper alloy is welded to the free end of the copper part of the sheets.

Title: Process for making a waffle filled with a liquid filling
Inventor: FOELL GERHARD E
IPC: A21D13/08
Filed: 1981-10-28
Abstract: The invention relates to making a waffle filled with a liquid filling such as honey, egg liqueur or syrup, which contains the liquid filling in a waffle sheet containing impressions, on which a covering waffle sheet is situated. At least the waffle half containing the impression is baked thoroughly in a waffle iron under pressure at temperatures of 240 DEG  to 350 DEG  and then the liquid filling is filled into the impressions of the waffle half provided. Subsequently, a food glue, which is impervious in relation to the liquid filling, is applied seamlessly to the points of the waffles containing the liquid filling which come into contact with the covering waffle, or as a film covering the entire filled waffle half, and a waffle cover sheet is placed thereon. The process makes it possible to make a waffle filled with a liquid filling, which contains the liquid filling - which possibly hardens during storage - permanently, without the liquid filling penetrating the waffle mass or at the edges.

Patent DE-3209541-A1 (DE)
Title: Baking oven
Inventor: GERL JOSEF
IPC: F24C15/20
Filed: 1982-03-16
Abstract: In cooking in the baking oven, steam (vapour) is created to a greater or lesser extent, which is guided through the vapour extractor with the aid of the cooling blower to the outside. In known baking ovens, the cooling blower is switched on together with the baking oven, irrespectively of whether vapour is created or not. According to the invention, there is arranged in the vapour flow path a moisture-dependent switch or its sensing member which serves to control the cooling blower. Since in baking or roasting in the baking oven an increasing baking oven temperature is usually associated with more vapour development, it is ensured in this manner that the cooling blower only runs when cooling is actually necessary. <IMAGE>

Abstract: There have been tripods for cameras of every type for a long time. But the invention which I believe to have made is only for video cameras. A motor-operated tripod for rotating, lowering and raising. Hitherto, the video camera always had to be operated manually, that is to say one had to stand behind it so that it was not possible to be involved in the actual happening. The radio remote control now makes it possible that everyone can operate and admire the entire happening, even from the easy chair. The video camera VK 800 E modified by me, the switches installed on the handle of the video camera, pause-on-off during recording, focusing, telephoto objective, wide angle objective. The advantage also consists in being able to follow that which is to be recorded on the TV screen.
Patent DE-3238421-A1 (DE)
Title: Pumping device for liquid or gaseous media
Inventor: SCHIPPERS HEINZ DIPL ING DR
IPC: F25B15/02
Filed: 1982-10-16
Abstract: The subject of the application is a controllable pumping device, in particular a displacement pump, for liquid or gaseous media which lies in a pipeline which can be hermetically sealed off so that any aggressive, toxic or otherwise difficult-to-handle medium cannot escape. The invention is described with reference to the example of a diaphragm pump (1) for pumping the solution saturated with ammonia from the absorber to the expeller of an absorption heat pumping system. It essentially consists of the fact that a flow of working medium is pumped pulsatingly to the drive chamber (3.1) of the diaphragm pump (1) by a constant pump (4) run at constant speed, the delivery flow being either admitted to the drive chamber (3.1) through a control valve (6) or diverted into the tank (11) and the working medium being released from the drive chamber (3.1) of the diaphragm pump (1) likewise into the tank (11). The control valve (6) is thereby controlled, that is opened and closed, as a function of a suitable process parameter, for example the heat content of a heat source (exhaust air, environmental air), by a control device (10.1). Embodiments of control valves (6) and preferred control diagrams are also described. <IMAGE>

Patent DE-3246588-A1 (DE)
Title: Structural element consisting of a hollow body which can be sealed air-tight and vapour-tight by walls and rigid or mobile sealing bodies
Inventor: BECKER OTTO ALFRED DR
IPC: E04G21/12
Filed: 1982-12-16
Abstract: The subject of this application are illustrative examples relating to the use of expanding mixtures of substances in stressed hollow bodies, especially in steel pipes to effect a predetermined longitudinal stress and hence to obtain an enhanced flexural strength and load-bearing capacity. The individual substances of the mixture are introduced in accordance with the increase in volume required for stressing the hollow body. Owing to their heat of reaction and/or to acids, they release gases from other substances also mixed in, which gases form chemical compounds with the other substances and/or penetrate these to form pores. In this way, high load-bearing, flexurally strong and at the same time relatively light-weight structural elements can be produced. Calcium oxide with admixed bicarbonate is listed as an example of a substance. By addition of water, calcium hydroxide is formed which, owing to the heat of reaction, evolves carbon dioxide from the bicarbonate. This carbon dioxide is bound to the calcium hydroxide forming hard calcium carbonate which is still made porous, before it hardens, by the excess of evolved carbon dioxide, all the substance particles being firmly bonded to one another. Suitable fillers are especially cements and aluminates. As a result of the formation of crystal needles and crystal platelets, ...
