Patent DE-3148162-A1 (DE)
Title: Gas heating system
IPC: F24H9/00
Filed: 1981-12-05
Abstract: The invention relates to a heating system, in particular for vehicles and weekend houses, with a closed combustion chamber which is heated by open flames of a combustion gas and which delivers the heat to the air which is situated in a heating housing surrounding the combustion chamber and which is distributed in the room to be heated by means of a heater fan. In order to be able to go without batteries for operation of the heater fan, there is arranged in the combustion chamber at least one thermoelectric generator which produces the current necessary for the electric blower motor from the flame heat in the combustion chamber. The thermoelectric generator can be connected to a battery by a switch, in order to actuate the ignition device for the gas flames if required. Furthermore, it is possible to use the current produced by the thermoelectric generator simultaneously for operation of a combustion air fan.

Title: Process for producing heat-resistant dispersion-hardened aluminium alloys
Inventor: RUEHLE MANFRED DR
IPC: C22C1/02
Filed: 1982-03-11
Abstract: The invention relates to a process for producing heat-resistant dispersion-hardened aluminium alloys which are ductile even at high temperatures. Hitherto it was only possible to produce such alloys by cooling the melt after adding the silicide-forming metals by granulation at very high speed and then processing the granular material by rolling or extruding to form a semifinished product. It is proposed to add silicide-forming metals in the form of alkali-metal fluoride compounds or as a mixture of metal-fluoride compounds with alkali-metal compounds to a melt composed of 0.5 to 19% by weight of silicon, the remainder, including the usual unavoidable impurities, being aluminium, at less than 900 DEG C and then to cast the melt within not more than 30 minutes to produce mouldings or blocks. In this way, mouldings or semifinished products can be produced much more economically.
Patent DE-3209149-A1 (DE)
Inventor: TIMPL RUPERT DR
IPC: G01N33/543
Filed: 1982-03-13
Abstract: The antigens procollagen peptide (type (III) and procollagen peptide col 1 (type III) can be determined together immunologically by either (a) reacting a specified amount in each case of labeled procollagen peptide (type III) or procollagen peptide col 1 (type III) and a highly specific antiserum containing antibodies having affinity for both the antigens mentioned together with a sample having an unknown content of procollagen peptide (type III) and/or procollagen peptide col 1 (type III), separating off the antigen-antibody complex formed and measuring the amount of labeling in the complex and/or in the supernatant, or (b) bringing a specified amount of the highly specific antiserum to reaction with a sample having an unknown content of procollagen peptide (type III) and/or procollagen peptide col 1 (type III), fixing the unreacted amount of the antibody to procollagen peptide (type III) or procollagen peptide col 1 (type III) bound to a support, and bringing to reaction with a labeled second antibody, and then determining the amount of bound or excess second antibody by measuring the labeling. An anti-procollagen peptide col 1 (type III) serum is preferred as the highly specific serum, and this is obtained by using procollagen peptide col 1 (type III) for immunizing experimental animals and obtaining their serum.

Inventor: GAERTNER FRANZ
IPC: B65G19/02
Filed: 1982-04-16
Abstract: According to the invention, a device for transporting supporting elements of suspended conveyors obliquely upwards in a reliable manner is provided. For this purpose, two chain tubes (1) are placed one above the other and, for example, welded together. These chain tubes (1) are cut out on the inside, in such a way that a chain (9) can be guided in them. Grippers (10) running up against a flat iron bar (15) are provided on the chain links, the flat iron bar (15) being fastened to the supporting shackle (16); the article to be conveyed is suspended on the supporting shackle (16). When the endless chain (9) is moved by being driven by means of a chain wheel, the grippers (10) run up against the flat iron bar (15) and take up the supporting shackles. In this way, conveyance can also take place relatively steeply upwards; or, where a sloping rail is concerned, in this way the supporting shackle (16) can be held and conveyed downwards at a desired speed. The supporting shackle (16) runs with its rollers (13) on the lower chain tube (1). <IMAGE>

Title: Limb protection for sportsmen, especially a shinpad
Inventor: BENTE ALFRED
IPC: A63B71/12
Filed: 1982-07-07
Abstract: A limb protection for sportsmen, especially a shinpad, comprises a dimensionally stable shell (1) which is roughly matched to suit the body part to be protected and is preferably made of a plastic and has a cushioning (3).

Title: X-ray image storage screen
Inventor: DEGENHARDT HEINZ DIPL CHEM DR
IPC: G21K4/00
Filed: 1983-02-08
Abstract: The invention relates to X-ray image storage screens in which X-ray images can be held fast by capturing electrons in storage places. The electrons can then be liberated again line by line, for instance, by scanning with an infrared beam and used as an image signal. The known substances used in storage layers, however, have low infrared stimulatability and great inertia. As storage substance the invention proposes barium (Ba) fluorohalide (FX, in which X = Cl, Br, and/or I) activated with europium (Eu), containing as donors trivalent cations of the fifth group of the periodic system of elements, i.e. those of arsenic (As), antimony (Sb) and/or bismuth (Bi). In this way, particularly if X = Cl and Y = As, there is obtained a substance BaFX : Eu : Y which gives rapidly responding, highly sensitive storage screens. A storage screen in accordance with the invention can be used, in particular, in medical X-ray diagnosis (X-ray television). <IMAGE>

Title: Control device for an extension device
Inventor: DREBING GERD
IPC: A61H1/02
Filed: 1983-03-12
Abstract: The invention relates to a control device for extension devices in which the traction force prevailing in a traction rope for the extension of body parts or extremities of a patient is translated in a linear deflection movement and is converted to digital values with an encoding disc. The digital, selectively encoded signals are compared with target values entered in digital form and cause control of the traction rope motor as a function of the target value-actual value comparison of the traction force and as a function of the particular type of treatment set in an electronics program. A plurality of safety switches guarantee interruption of the energy supply to the traction rope motor, so that malfunction can be ruled out. Besides a large variety of treatments it is possible to set the particular traction force required in arbitrary digital steps and, in addition, to ensure exact adjustment of the active and passive pauses during treatment in intermittent and periodic operation. A monitoring circuit which causes triggering of an alarm on failure of one of the digital measurement pick-up elements and interrupts energy supply to the traction rope motor is provided for self-monitoring of the control circuit.
