Title: Cooling tunnel for the controlled forced cooling of heated material, in particular castings
Inventor: RUEHL RAINER DIPL ING
IPC: B22D30/00
Filed: 1981-01-02
Abstract: The invention relates to a cooling tunnel for the controlled forced cooling of hot shaken-out castings or similar material to be cooled. The invention makes possible essentially continuous production following the shake-out process up to the blast cleaning process and renders superfluous an additional heat treatment, which is sometimes necessary. The aim of the invention is an improvement in the service properties of known apparatuses, in particular immediate accessibility to the cooling tunnel in the event of repairs and reduction of coolant consumption. It is the object of the invention to reduce heating up of the outer wall and reduce the consumption of coolants. The core of the invention consists in the fact that the cooling tunnel comprises three sections, which have enclosed build-up spaces above and below the nozzle plates and lateral guiding devices for the gaseous coolant guided in cross-flow, the said devices simultaneously forming a heat protection for the housing. Assigned to the nozzle plates in the central section are means capable of being switched off for atomising a liquid coolant as well as further control means.

Title: Method of producing a model for dental prosthetic work
Inventor: BADEMIS JOANNIS
IPC: A61C13/34
Filed: 1981-03-19
Abstract: In the method of producing a model (34) for dental prosthetic work with at least one epimobile attachment (5) of a jaw implant which can be fastened on an implant body embedded in the jaw, a transmission cap (18) is initially pushed tightly over the epimobile attachment (5) built up over the implant body in the mouth, and by this a mould (33) with the transmission cap (18) firmly embedded in the moulding composition is obtained by impression in the mouth. The mould (33) is then peeled off with the transmission cap (18) and the epimobile attachment (5) which has been released from the implant body and has instead been connected to a laboratory implant (11) simulating the implant body is repositioned in the transmission cap (18) outside the mouth. Finally, the mould (33) fitted in this way with the laboratory implant (11) is poured in order to obtain the model (34), and at the same time the laboratory implant (11) is firmly cast into the model body. The model (34) thus obtained reflects very closely the situation in the mouth. The method ensures that the epimobile attachment (5) in the model (34) sits in exactly the same position on the laboratory implant (11) as in the mouth on the implant body embedded in the jaw. <IMAGE>

Patent DE-3207862-A1 (DE)
Title: Chemical plant with nuclear reactor
Inventor: WIESER RUDOLF DR
IPC: G21D9/00
Filed: 1982-03-05
Abstract: It is also planned to use nuclear reactors, particularly high-temperature reactors, in future for supplying process heat to chemical plants. Where high-temperature reactors are used, the process heat is to be supplied at a temperature between 900 and 950 DEG C, as is necessary, for example, for the gasification of coal. At present, the supply of process heat at such a high level of temperature is impossible because the maximum-temperature heat exchangers, which are necessary to couple out the process heat from the primary helium circuit of the high-temperature reactor, have not yet been tested adequately in terms of material. To eliminate this difficulty and to accelerate the practical use of the high-temperature reactor for supplying process heat, the invention proposes to couple out the process heat from the reactor at a temperature of only about 700 DEG C and to carry out heating over the remaining interval (from 700 to 900-950 DEG C) using a high-temperature compressor. If the primary chemical material components are all gaseous, compression to 900-950 DEG C can also be carried out directly using said material components. <IMAGE>

Patent DE-3236439-A1 (DE)
Title: Gasifying oil burner
Inventor: KOTZMANN HEINZ
IPC: F23D11/40
Filed: 1982-10-01
Abstract: A gasifying oil burner is proposed, in which, in a jacket tube which also receives the nozzle connection, the air flow undergoes a screw motion by means of a twist ring, which motion then creates in the region of the oil-spraying cone root a certain low pressure, then to be, downstream of the root, reflected on the tube wall of a flame tube and thrown, transversely to the cone envelope, onto the latter. As a result of this, there is an intensive mixing with regions of different oiliness of the fuel/air mixture. In the rich regions, optical flame monitoring is possible as a result of the yellow flame which forms. The lean regions downstream bring about complete combustion of the fuel, in particular in the form of a blue flame. According to one embodiment, there is arranged transversely to the oil-spraying cone a bowl which brings about additional twisting and reflection of the fuel/air mixture and moreover serves as pre-combustion chamber, by means of which an at least partial gasification of the oil is effected.
