IPC: F04D29/08
Filed: 1968-06-20
Abstract: 1,234,061. Centrifugal fans and pumps. BROWN BOVERI & CO. Ltd. June 20, 1968 [June 22, 1967], No.29562/68. Heading F1C. [Also in Divisions G6; H2] In a single or multi-stage fan or pump arrangement, e. g. for circulating gas or liquid within the pressure vessel 11 of a nuclear reactor, the fan or pump and the driving motor are removably mounted as a unit within a bore 10 in the wall of the pressure vessel. Removal of the unit is effected by retraction of a clamping ring 13 by piston means 29, whereafter a spring 22 or the like causes a closure member 23 and the unit, and later a closure member 24, to move axially of the bore until sealing surfaces 33, 35 are in abutment with sealing surfaces 34, 36 respectively, to isolate the bore from the interior of the pressure vessel. The pressure in a chamber 30 may be reduced to create a pressure differential to supplement the force exerted by the spring 22. The motor housing 7 is supported in the bore either on rollers or on gas bearings 39 receiving pressurized gas via passages 40 only during removal or replacement of the unit. Once the bore is isolated from the interior of the pressure vessel, the unit can be removed therefrom after the bore has been filled with ambient air, a cover 15 has been removed, and helical pipelines 41 and electrical cables 42 have been disconnected from a flange member 43. During reassembly, once the unit is inserted into the bore, and the cover 15, pipelines 41 and cables 42 are reconnected, the chamber 30 is pressurized to move the unit against the action of the spring and the pressure within the vessel, to its operating position shown. The closure member 24 carries sealing rings 37a, 37b between which gas may be withdrawn via ducts 38 to enhance sealing, or pressurized fluid may be supplied therethrough to break the seal, when the closure members 23, 24 are in the closed position. The shaft 1 is mounted in a pair of hydrodynamically lubricated bearings 6 carried by flexible diaphragms 9, and has at one end a thrust bearing 5 supported via a universal-type mounting 8. The motor is cooled by a water cooler 16.

Abstract: 1,234,192. Heat-treating coated articles. CENTRE STEPHANOIS DE RECHERCHE MECANIQUE HYDROMECANIQUE ET FROTTEMENT. May 16, 1968 [May 16, 1967; July 12, 1967; Nov. 24, 1967; March 12, 1968], No.23431/68. Heading C7B. A method of treating the surface of a metal part B intended for frictional contact with a part A, comprises depositing a layer comprising or consisting of a metal D and subsequently heattreating. The part B contains a metal C which is capable of forming a hard alloy with metal D, C being either an alloying ingredient of B or being deposited thereon as a layer prior to deposition of D. The heat-treatment comprises first maintaining at a temperature lower by at least 20‹ C. than the lowest melting point of the metals involved to cause limited diffusion between the layers and/ or between these layers and the substrate B, and then maintaining at a temperature higher than the said lowest melting point but less than 800‹ C. to form a composite layer comprising either (1) a layer comprising or consisting of D, an intermediate layer comprising a hard alloy of C and D and underlying B or (2) a composite layer as in (1) with a residual layer of C between the hard alloy layer and underlying B. An additional layer of metal C or another metal E may be provided the metal E being substantially non-alloyable with A and C. In the examples, heat-treatment follows the application of coatings by electrolytic processes. Annealed steel is coated with copper and then tin or indium or indium-lead alloy; bronze or stainless steel or a copper-aluminium alloy are coated with tin.

Abstract: 1,239,255. Particle detectors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 Oct., 1968 [9 Oct., 1967], No. 47137/68. Heading H1K. A particle detector comprises a semi-conductor wafer with a rectifying junction between its major faces, a continuous electrode on one face, and a semi-conductor layer of the same conductivity type as but lower resistivity than the adjacent wafer material grown epitaxially on the opposite face and carrying on its outer surface at least two spaced electrodes. A typical device, Fig. 1, is made by depositing epitaxially a phosphorus doped 10 Á thick layer 5 of N-type silicon of 10-10<SP>-2</SP> ohm. cm. resistivity on one face of a 300-10,000 ohm. cm. N-type silicon wafer 3. After cleaning in a nitric-hydrofluoricacetic acid mixture the opposite surface is exposed to air to form an inversion layer 2 and electrodes 1, 6, 7 applied. In operation the junction between layer 2 and the body is reverse biased to extend the depletion layer as far as layer 5. An alternative way of making the device for operation at low voltage is to grow the epitaxial layer to a thickness of 150- 200 Á and then reduce the wafer thickness to 10 Á by grinding and etching the opposite face before forming the inversion layer and electrodes.
