Inventor: SCHOENWALD SIEGFRIED
IPC: G11B15/58

Abstract: A valve for controlling a pressure differential between a high and low pressure, characterized by a housing being sub-divided by a transfer port into a first and second chamber, each having ports, a valve member movable in the first chamber to close the transfer port, a spring arrangement for urging the valve member to a closing position, a membrane extending across an opening end of the housing, which is in communication with the first chamber and held on by a cap forming a third chamber having a port and means for connecting the valve member to the membrane so that when a pressure differential between the pressure in the first chamber and third chamber exceeds the value of the spring arrangement, the transfer port is open to allow passage of the pressure in the first chamber into the second chamber. The valve can be used in controlling a compressor by allowing the dumping of the output of the compressor when the pressure differential is exceeded and can be used for controlling a vacuum system by dumping ambient air into the vacuum system when the vacuum exceeds a certain amount. In addition, the valve can be utilized for maintaining a pressure differential on a tape loop box of a reel-to-reel magnetic tape recorder.

Abstract: The present invention relates to a process for the production of chromium-aluminum balls for adding chromium into molten aluminum baths. In order to obtain balls containing x% of chromium and y% of aluminum, where x and y are gravimetric contents corresponding to the following relationships: 70</=x</=80 20</=y</=30 x+y=100 an alloy of chromium and aluminum containing gravimetric chromium and aluminum contents approximating to x by an excess and to y by a deficit respectively is prepared by melting and this alloy is then finely ground into a crude powder; the chromium and aluminum contents of the alloy or of the crude powder are determined and, if required, an additional amount of finely divided aluminum is added so as to obtain a powder containing x% of chromium and y% of aluminum, the additional amount of finely divided aluminum corresponding to less than 10% by weight of the crude powder; a compacting is then carried out. Balls essentially consisting of alloy particles having the same melting point and little risk of floating on the surface of the molten aluminum bath, which favors the dissolution of the balls in the latter, are produced.

Abstract: A flat sealing ring (3) has a rectangular cross-section. As a result of the design of the sealing surfaces on the components (1, 2) to be sealed, a plate spring-like bending with simultaneously compressing deformation of the sealing ring (3) takes place, as a result of which excellent sealing is ensured, even with extremely small pressing forces. In this case, the range of use extends from ultra-high vacuum up to high pressure, and from cryogenic temperatures up to high temperatures. Because of the relatively simple geometry of the sealing edges, these can be produced extremely cost-effectively, with commercially available processing tools.

Abstract: Polycrystalline silicon is deposited in a film onto the surface of a substrate which has been carefully prepared to eliminate any defects or contaminants which could nucleate crystal growth on the substrate. The deposition is carried out by low pressure decomposition of silane at substantially 580 DEG  C. to cause a film of fine grained crystals of polysilicon to be formed having grain sizes averaging less than about 300 Angstroms after annealing. Such a film is very uniform and smooth, having a surface roughness less than about 100 Angstroms RMS. Annealing of the film and substrate at a low temperature results in a compressive strain in the field that decreases over the annealing time, annealing at high temperatures (e.g., over 1050 DEG  C.) yields substantially zero strain in the film, and annealing at intermediate temperatures (e.g., 650 DEG  C. to 950 DEG  C.) yields tensile strain at varying strain levels depending on the annealing temperature and time. Further processing of the polysilicon films and the substrate can yield isolated diaphragms of the polysilicon film which are supported only at edges by the substrate and which have substantial lateral dimensions, e.g., 1 cm by 1 cm. Such that structures can be used as pressure sensor diaphragms, X-ray masks, and optical filters, and can be provided with holes of varying sizes, shape and number, which can serve as X-ray mask patterns. The diaphragms can be provided with numerous holes of uniform size and spacing which allows the diaphragms to be used as filters in ultrafiltration applications.
