Patent DE-3118396-A1 (DE)
Inventor: HANNEN RAINER WILHELM
IPC: B65B53/06
Filed: 1981-05-09
Abstract: The invention concerns an apparatus for producing a hot gas to shrink plastic foils, with at least one burner mounted in a housing provided with a discharge nozzle for the hot gas. To better control the hot-gas temperature and hence the temperature of shrinking, the apparatus is provided with such a burner arrangement that the hot-gas jet (9 or 10) leaving the burner (7 or 8) is directed at an angle to the discharge flow defined by the discharge nozzle (6) and with a jet-deflection means for the hot-gas jet (9 or 10) before the discharge nozzle (6). In a preferred embodiment the jet deflection is implemented by a jet (17) of cold air by means of which the hot-gas jet (9 or 10) is simultaneously directed and cooled. In a preferred mode, the pressure and the flow rate of the cold-air jet (17) are controlled.

Title: Process for the production of polycrystals of a boron nitride consisting of dense modifications
Inventor: ZDANOVIC GENNADIJ MICHAJLOVIC
IPC: C04B35/5831
Filed: 1981-06-29
Abstract: The invention relates to extremely hard materials and in particular to a process for the production of polycrystals of a boron nitride consisting of dense modifications. The process for the production of polycrystals of a boron nitride consisting of dense modifications comprises the preparation of a batch from the hexagonal boron nitride with or without addition of alloy, the pressing of the batch at a pressure of 3 to 8 kbar, the action of high pressures and temperatures on the semi-finished product obtained in two stages, the semi-finished product being exposed initially to the action of a pressure of 100 to 150 kbar at a temperature of 290 to 1500 K. The treatment time for this stage must be sufficient for the conversion of at least 15% by weight of hexagonal boron nitride to the wurtzite modification. In the second stage, the compacted material obtained is exposed to the action of pressure of 40 to 90 kbar at a temperature of 1600 to 3200 K. The treatment time for the second step must be sufficient for the complete conversion of the hexagonal boron nitride to its dense modifications. The invention will find its use in the production of cutting tools such as chisels, boring crowns, milling machines and the like for the machining of very hard articles.

Title: Process and equipment for heat recovery
Inventor: BORMANN GEORG VON DIPL ING
IPC: F24V30/00
Filed: 1982-01-23
Abstract: A process or equipment for heat recovery, in which the medium to be heated is fed into a return line from a radiator or the like of a heat-generating device and, heated by the latter, is returned again via a forward line, is intended, inter alia, to open up the possibility of utilising hitherto unexploited means or chemical processes for heat generation, which produce the smallest possible quantity of waste or re-usable waste and relieve the environment. For this purpose, the medium to be heated is passed in the heat-generating device through an oxidising medium, preferably in loops (15) of the return line (11), and in a loop shell (16), surrounding the loops (15), through readily oxidisable metal filings (14) to the forward line (9). The heat-generating device (10) consists of a vessel (12), whose interior (J) is penetrated by parts (15) of the return line (11) and parts (16) of the forward line (9) and is filled with an oxidising medium (14) which surrounds the parts (15 and 16). <IMAGE>
Patent DE-3202627-A1 (DE)
Title: Method of conveying a sterilising medium out of a sterilizer, and an apparatus for carrying out the method
IPC: A61L2/20
Filed: 1982-01-25
Abstract: The invention relates to a method of conveying a sterilising medium, such as steam or chemical gas, out of the pressure chamber of a sterilizer, and to an apparatus for carrying out the method, which rule out any harmful influence on the ambient air on opening the door of the pressure chamber of the sterilizer. For this purpose, one region of the wall of the pressure chamber is cooled by a thermostat from the outside and/or from the inside after pressure compensation, in such a way that the remaining sterilising medium in the pressure chamber is completely condensed in the pressure chamber. At the end of the batch, while maintaining the superatmospheric pressure, one region of the wall of the pressure chamber can be cooled by a thermostat from the outside and/or from the inside in such a way that the used sterilising medium is completely condensed in the pressure chamber, whereupon the entire condensate is forced out of the pressure chamber during the subsequent pressure equalisation.

Title: Wall building element for an absorber outer wall
Inventor: BANNASCH ULRICH DIPL ING
IPC: F24D3/18
Filed: 1982-02-17
Abstract: A wall building element for an absorber outer wall of a building should, on the one hand, provide adequate heat insulation in terms of constructional engineering and be suitable, on the other hand, as an absorber carrier, and in this case, in particular, condensation-moisture formation associated with heat absorption should not lead to damage to the wall building element. The wall building element therefore consists of a porous material. Arranged in its outer surface region is a pipe grid which is fixed by means of a heat-conducting mortar and is covered towards the outside. The pores of the stone material take up the moisture produced on the pipe grid.

Title: Piston steam engine with built-in compressor
Inventor: OSTERBURG GUENTER
IPC: F01B29/12
Filed: 1982-04-17
Abstract: The aim of the invention is to reduce the construction cost and the overall volume of piston steam engines with compressors which are to be used mainly as heat pump units. An optimum solution has been achieved by combining two units into one unit. Because the same material, for example fluorohydrocarbons, are used in the drive section and in the compressor section, migrations of the working material from the Rankine cycle into the heat pump circuit due to insufficient sealing do not have any effect. The heat pump unit can be incorporated into any heating boiler and open fireplace so that in two-condition heating operation an annual fuel ratio of approx. 1.60 is to be anticipated, so that the fuel consumption is reduced by half.

Title: Device for transporting patients
Inventor: SCHUMANN ERWIN
IPC: A61G5/00
Filed: 1982-05-24
Abstract: Patients are generally transported using devices, especially stretchers or stretcher trollies or wheelchairs, which essentially comprise a frame which can be assembled by means of supports. During transport, especially during a journey in an ambulance or rail or other means of transport, there arise vertical shaking movements, in particular, which are transmitted to the stretchers or wheelchairs and thus to the patients themselves. These shaking movements are extremely unpleasant, and usually painful, for the patients. In order to provide a device for transporting patients which remedies this shortcoming and provides patients with a substantial degree of protection against shocks, it is provided according to the invention that a spring device be provided between each support and the frame, which is designed and matched in such a way that the shaking movements occurring during transport are absorbed.

Title: Valve for a line carrying explosive fluids
Inventor: VOLZ BERNHARD DIPL ING
IPC: F16K1/44
Filed: 1982-11-04
Abstract: The invention relates to a valve for a line carrying explosive fluids, having a valve cone and a valve seat. A valve is detonation-proof from only one side. Stop-cocks are therefore normally used. However, when a stop-cock is operated, the flow path is interrupted or released abruptly. However, ignition of the explosive fluid can be initiated as a consequence of adiabatic compression. As a shut-off fitting which is detonation-proof from both sides and in which the formation of pressure shocks during its operation is prevented, a valve is proposed according to the invention which is characterised by a further valve cone which is arranged in front of the first valve cone in the flow direction of the fluid, and by a further valve seat which interacts with the further valve cone. In this case, the valve seats are arranged between the two valve cones.
