Title: Automatic telecommunication exchanges
IPC: H04Q3/00
Filed: 1960-12-05
Abstract: 896,696. Automatic - exchange systems. STANDARD TELEPHONES & CABLES Ltd. (Standard Elektrik Lorenz A.G.). Dec. 5, 1960, No. 41758/60. Class 40 (4). In a two-stage switching network in which, when all direct paths between the stages A, B (Fig. 1), are busy, a connection is set up via the overflow stage U, this overflow connection is replaced by a direct connection as soon as the direct path becomes free. A direct connection is set up from A11 to B11 by the energization of coupling relays AX, BX (Fig. 3), when a marker (not shown) moves the points k and az, and bz and g, respectively. These relays and AZ hold over the c wire. A further connection between the same two switches is set up by the energization of relays AUY, AUZ, U, UZ and BUY, the connection extending via the overflow stage U (Fig. 1). When the first connection is released, the relapse of AZ (Fig. 3) brings up UU which operates AY, AZ and BY to complete a direct connection, M coming up with delay. The last relay brings down AUY, AUZ, U, UZ and BUY whereby the indirect connection is released. The switches may be cross-bar or cross-coil selectors.

Title: Forced through-flow steam generators
IPC: F22D11/00
Filed: 1960-12-05
Abstract: 924,227. Fluid-pressure servomotor systems. SULZER FRERES S.A. Dec. 5, 1960 [Dec. 15, 1959], No. 41794/60. Class 135. [Also in Group XIII] A forced-flow, once-through steam generator, Fig. 4, comprising a feed pump 1, preheaters 3, 4, an evaporator 5 and a superheater 7 incorporates a liquid separator 6 which is disposed upstream of the superheater 7 and has a discharge valve 12 regulated by a unit 8 proportionally to the liquid content of the separator, the unit 8 also influencing a feed regulating unit 10 which has imposed upon it, at the same time, a signal derived from a working medium flow-measuring unit 14 so that the ratio of the discharge flow to the flow of working medium is a function of the load. The unit 14 is connected through a converting unit 38 and a line 15 to the unit 10 the latter controlling a feed-regulating valve 2. As shown in Fig. 5, the flow-measuring unit 14 comprises a restrictor 21 connected to a pressure differencedetecting element 14 having its diaphragm linked by a rod 22 to a pivoted cam 38 a roller 25 on which is connected by a rod 26 to a lever 28 which has a fulcrum 27 and bears against a spring 29. Pivotal clockwise movement of the lever 28, as the load increases, is transferred through a link 30 to a second lever 31 which pivots about a temporary fulcrum at the junction with a linkage 34 connected to the discharge valve 12 to reduce the pressure in the regulating unit 33 which through lines 41, 13 and a central unit 10, influences a servomotor 42 which correspondingly opens the valve 2. The resultant increase in the supply of feed-water causes the liquid level in the separator to rise and raise the pressure below the diaphragm of the detector 8 a rod 37, interconnecting the diaphragm and a bellcrank lever 35 rotating the latter in a clockwise direction and, through the linkage 34, increasing the cross-section of the discharge valve 12. At the same time the lever 31 is also turned in a clockwise direction about the pivotal connection with the link 30 so that action is initiated to decrease the cross-sectional area of the valve 2. The amount of water discharged from the separator and the amount of feed are increased and decreased respectively until a state of equilibrium is reached. Coolant flows through a tube 17 to cool the liquid before it is discharged from the separator 6. The restrictor 21 may be located between the valve 2 and the preheater 3. Specification 758,833 is referred to.

Title: Improvements in or relating to olefin oxide polymers
IPC: B29C67/00
Filed: 1961-11-23
Abstract: 973,476. Films of olefine oxide polymers. UNION CARBIDE CORPORATION. Nov. 23, 1961 [Dec. 8, 1960], No. 41909/61, Heading B5B. The stress endurance of a film comprised essentially of olefine oxide polymer is improved by subjecting the film, while at a temperature below the melting-point or first order transition to simultaneous application of compressive force and concentric shearing action. The latter is defined as the shearing force exerted between adjacent layers of a film when it is passed between converging rolls. The compressive force is of such magnitude as to cause substantial flow of polymer in a plane perpendicular to the direction of the applied compressive force, thus causing a reduction of film thickness, e.g. of from one-tenth to one half. The forces of compression, shear and the tension resulting therefrom, may be applied by a process of cold-rolling wherein a web of film is passed between the nip of adjacent cylindrical metal rolls. The polymer may be a homopolymer of e.g. ethylene oxide, or a copolymer, e.g. a copolymer comprised of at least 50% of ethylene oxide and up to 50% of either propylene oxide or butylene oxide. In examples, poly(ethylene oxide) films are cold-rolled at 10-25‹ C. The process may also be applied to wires, yarns and filaments coated with a polymeric olefine oxide.

Filed: 1964-10-14
Abstract: 1,082,317. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Oct. 14, 1964 [Dec. 17, 1963; Feb. 25, 1964; Aug. 7, 1964], No. 41932/64. Heading H1K. A surface 80 at which one or more PN junctions 63, 65 emerge is covered with an oxide layer 66 and has metallic electrodes 67-70 contacting the semi-conductor through apertures in the oxide. Each electrode consists of a first or " active " layer of one of the metals Ti, Ta, Zr, Nb, Cr, Hf, V and at least one superposed " contact " layer of Pt, Az, Au, Ni, Pd, Rh or Al. Each PN junction meeting the surface is covered by the oxide and the projection of each such junction falls within the area of at least the contact layer of one of the electrodes. In the transistor shown the emitter and base electrodes 67 and 68 overlap the junctions in this way: there are also two collector electrodes 69, 70. A further oxide layer 71 covers the electrodes except for apertures through which lead-out strips 72 to 75 contact them. These strips are also multilayers of the same structure as the underlying electrodes 67 to 70. In Fig. 3 (not shown) is depicted a diode in which there is one such twolayer electrode overlying the only PN junction and with its first layer penetrating a single oxide coating. In either device the active layer may be deposited on exposed semi-conductor which has first been covered with a sputtered or evaporated platinum layer which, by a subsequent heat treatment, was collected into discrete " islands " on the semi-conductor before the active layer was applied. This active layer and also the contact layer, may be applied by sputtering or evaporation, conveniently through a mask and the layers integrated by electroforming. Once deposited, the electrodes may be shaped by a reverse sputtering technique, as described in Specification 1,082,318. A counter-electrode (not shown) of Ni or Au, may be applied to the substrate 61 in the case of the diode embodiment. The semi-conductor is Si, Ge, or Ga-As, diffusively doped using the oxide coating as a mask. The lead-out strips of the transistor shown may be further covered with oxide and surmounted by further multimetal layers in the form of " skull-caps " over the PN junctions. The strips may extend beyond the edges of the semi-conductor body and be of sufficient thickness to provide mechanical support. An integrated circuit, consisting of a plurality of devices with such thickened projecting strips, may be manufactured by forming all the elements of the circuit in a single semi-conductor body and then separating them by etching away the semi-conductor material adjacent elements, leaving them physically isolated except for bridging connections formed by the thickened strips. Such a technique for forming integrated circuits is disclosed in Specification 1,082,319.

Title: Nuclear reactor fuel assembly arrangement
IPC: G21C3/356
Filed: 1973-09-10
Abstract: 1409611 Fuel elements WESTINGHOUSE ELECTRIC CORP 10 Sept 1973 [25 Sept 1972] 42421/73 Heading G6C A nuclear fuel assembly comprises (Fig. 1, not shown) an array of parallel fuel rods (14), structural tubes (12) composed of a metal having a relatively low neutron captive cross-section, and spacer grids 13 spaced along the tubes (12), the tubes (12) extending through retaining means positioned within the grid openings, thereby holding the retaining means in engagement with the grids 13, the retaining means being metallurgically bonded, such as by spot welding, to the tubes (12). The tubes (12), in addition to forming part of the basic fuel assembly structure, serve as guide thimbles for cylindrical control elements (27). In the embodiments described, the tubes (12) are fabricated from a zirconium base alloy (zircaloy) and the grids 13 from a nickel base high temperature alloy. In one embodiment (Figs. 2 and 3), the retaining means each comprise a short zircaloy sleeve 15 inserted into a grid cell. The sleeve configuration is such that the upper and lower edges 18, 19 of windows 17 machined into the sleeve 15 at 90 degrees to each other contact the outer edges of the grid 13 and so axially lock the sleeve 15 in position within the grid cell. Preferably two of the four windows 17 are machined through to the upper edge of the sleeve 15 forming slots 20 which permit the sleeve 15 to be elastically deformed by squeezing so that it may be inserted in the grid cell. When fully inserted, the squeezing pressure is released and the upper edges 18 of sleeve 15 snap into position over the upper edges of the grid straps 16. Insertion of a zircaloy tube (12) through the sleeve 15 prevents deflection of the sleeve walls and hence holds the sleeve 15 in engagement with the grid straps 16. The zircaloy tube (12) is then spot welded to the sleeve 15. The need for brazing the sleeve to the grid, which components are of dissimilar alloys, is eliminated by this invention. In an alternative embodiment (Fig. 7), two zircaloy sleeves 22 are required for each tube/grid joint and are inserted into the grid cell from opposite ends. The length of insertion into each grid cell is determined by the edges 23 of cut outs 24 provided in each sleeve 22. The cut outs 24 serve the same purpose as the windows 17 in the first embodiment, similarly the edges 23 serve the same purpose as the edges 18, 19 of sleeve 15.
