Patent DE-3016228-A1 (DE)
Title: Exhaust turbine for IC engine - has rotating heat exchanger acting as part of turbine rotor assembly
Inventor: STRIEBICH HELMUT DIPL ING
IPC: F02B41/10
Filed: 1980-04-26
Abstract: The IC engine has an exhaust turbine which also functions as a heat recovery unit. Exhaust gas from the engine is supplied through a tangential inlet (1), transfers mechanical energy and heat to turbine blades (4) and leaves through a tangential exhaust pipe (2). The turbine blades (4) are in the form of hollow circular section tubes which are mounted on a rotor assembly. The rotor assembly carries a compressor which supplies air through the centre of the blades (4) where it is heated. The air then expands in a secondary turbine which is also part of the rotor assembly. Power is taken from the rotor shaft.

Title: Radiation burners for tunnel kilns - where radial burner flames create pronounced circulation of gases in high temp. zone of kiln
Inventor: THIELE HARTWIG DR ING
IPC: F27B9/36
Filed: 1980-05-02
Abstract: This is an addn. to 131291, which described the use of special radiation burners for heating tunnel kilns and other furnaces used in the ceramics industry to make fine- or sanitary-ware, where high temps. and/or a uniform furnace atmos. are required. Novelty is that in the roof and/or the walls of the kiln are radiation burners which produce a radial, flat flame causing pronounced circulation of the gases in the kiln. A gas or flame deflector is pref. located at the level of the hollow podium. Productivity is increased but the specific fuel consumption is substantially reduced, and the working life of the bed along which the kiln cars travel is greatly increased.

Title: Anticancer preparations used in cases of excessive vitamin=C levels - esp. acute lymphatic leukaemia and bronchial carcinoma, contain the enzyme ascorbate oxidase
Inventor: LOHMANN W PROF DR
IPC: A61K38/44
Filed: 1980-11-18
Abstract: New pharmaceutical preparations for the treatment of cancer types exhibiting excessively high vitamin C concentrations (esp. acute lymphatic leukaemia and bronchial carcinoma) contain as active substance the enzyme ascorbate oxidase, opt. together with usual adjuvants and/or carrier substances. Ascorbate oxidase, which catalyses the aerobic oxidation of ascorbic acid to dehydroascorbic acid, occurs in various plants and can be isolated e.g. by the method of Eur.J.Biochem. 1979, 101, 65-76. Instead of the complete enzyme, the preparations may contain enzymatically active subunits of ascorbate oxidase. The preparations may also contain natural or synthetic substances or compounds having ascorbate oxidase-like activity. The dosage used is dependent on the ascorbate concn. in the cancer tissue.

Title: Method and device for converting digital signals into analog output variables which are allocated to a number of output channels
Inventor: DELAGO ERICH
IPC: H04Q9/00
Filed: 1981-05-30
Abstract: To convert signals which are present in digital form in a central processing unit (ZE) into analog output variables (A1, A2,...) which are allocated to a number of output channels (K1, K2,...), the digital signals are converted successively in time into analog signals in a central digital/analog converter (D/A) and output to an analog bus (ANB). At the same time, the central processing unit (ZE) sends out the associated address of the output channel (K1, K2,...) via an address bus (ADB). As soon as this address has been decoded by the address decoder (ADC) addressed, the analog value present on the analog bus (ANB) is accepted by a sample-and-hold circuit (S+H) and output via an output amplifier (V). <IMAGE>

Title: Process and equipment for heat recovery in directly steam-heated autoclaves
Inventor: HERRMANN KURT
IPC: F22D11/00
Filed: 1981-11-11
Abstract: The invention relates to a process and equipment for heat recovery in directly steam-heated autoclaves, the invention being intended in particular for application in brick-hardening vessels or processes which operate by similar mechanisms. The point here is to utilise the heat of the condensate arising in the autoclave and the heat of the flash steam and residual steam in the best possible way without carrying out special controls and switching steps. This is achieved essentially by carrying out the heat exchange between condensate, flash steam and residual steam with the fresh feedwater in two or more stages via an appropriate number of feedwater tanks (7, 12) with hot-water cascades (16, 13). The condensate is here passed first through a heat exchanger (6) to a condensate receiver (9), where a phase separation into steam and water takes place. The resulting values are slightly above atmospheric pressure, and the boiler feedwater is heated in the hot-water cascades to a temperature of more than 100 DEG C, utilising the condensate temperature. <IMAGE>
