Abstract: 1,132,222. Pipe connections. GASKELL & CHAMBERS Ltd. 11 Oct., 1966 [27 Oct., 1965], No. 45587/65. Heading F2G. An adaptor device for connecting a liquid dispensing pipe and a pressurized gas supply to a beverage container, such as a beer cask, comprises a first coupling part 10 formed by  components 12 and 15 having a through bore ‹ 16, a second coupling part 11 in which the first coupling part is slidably mounted, an annular gas passage 18 defined between the coupling parts and communicating with a gas supply port 19 when the device is secured to a container flange 27, a support member 26 adapted to be secured to the container and resiliently mounting the second member and an operating cam member 30 mounted on the support member and engageable with the first coupling part. On initial rotation of the cam member, the first and second coupling parts are urged downwards compressing springs 28 on pair of guide studs 25 (only one being shown) secured to the support member and open a closure member 14 in the container opening. The passage 18 is thus placed in communication with container interior. Further rotation of the cam member compresses a helical spring 22 to slidably depress the first coupling member with respect to the second coupling member thereby separating normally abutting shoulders 19 and 20 with an interposed seal 23 so that pressurized gas, such as carbon dioxide, can pass from supply port 19, through the gas passage 18 into the container. Liquid is then discharged past a non-return valve 17 through the bore 16. In a modification, Fig. 2 (not shown), the cam member is replaced by a screw stud (32) and the helical spring 22 replaced by an annular spring washer (36).

Title: Process and composition for separation of oxygen from air using pr-ce oxides as the carrier
IPC: C01F17/241
Filed: 1974-10-24
Abstract: 1489224 Oxygen separation UNION CARBIDE CORP 24 Oct 1974 [25 Oct 1973] 45984/74 Heading ClA Oxygen is separated from an O 2  containing gas mixture by oxidizing a Pr-Ce oxide mixture present in a "first oxidized state" by reacting with the gas mixture to convert at least a portion of the reaction mass into a relatively more "oxidized state" followed by separation of the O 2  depleted gas mixture from the relatively more oxidized Pr-Ce oxide reaction mass and then dissociating at least a portion of the oxidized mass to a relatively more reduced state of Pr-Ce oxide with liberation of O 2 ; the Pr-Ce oxide mixture and O 2  are then separated. The reaction masses may have the general formula (Pr x Ce y )O z  where x and y are the relative molar amounts of cations in the oxide materials and x + y = 1 and z varies from 1À5 to 2À0; at values of z = 2À0 the materials are in their fully oxidized state while at z = 1À5 they are at their lower limit of dissociation. The Pr-Ce oxide mixture may contain a surface dopant, e.g. Ag, which increases the resistance of the oxide material to the effects of CO 2  and H 2 O which may be present in the gas mixture. A Pr-Ce oxide reaction mass of general formula (Pr x Ce y )O z , containing a dopant, preferably silver, is synthesized by contacting an aqueous solution comprising the nitrate salts of Pr, Ce and dopant with excess precipitating agent with respect to the molar amount of Pr and Ce in the aqueous starting solution; the precipitated material is separated from the aqueous solution, dried and then calcined at 600-1000 C. to form the mixed oxide; the precipitating agent is selected from the group ammonium oxalate or hydroxide or oxalic acid.

Title: Production of semiconductor components
IPC: H01L21/00
Filed: 1963-11-25
Abstract: 1,058,067. Semi-conductor devices. SIEMENS & HALSKE A.G. Nov. 25, 1963 [Nov. 26, 1962], No. 46389/63. Heading H1K. [Also in Division G4. A device comprising a sequence of four or more zones alternately of opposite conductivity types is formed by gaseous impurity diffusion into a surface of a body or zone of one conductivity type through holes in a silicon dioxide mask to produce two zones of the opposite conductivity type and then diffusing or alloying impurity into at least one of these zones to form a zone therein of said one conductivity type. The spacing between adjacent PN junctions is such as to allow minority carrier flow between them. A plurality of such devices shown individually in Fig. 4 may be formed by first vapour depositing silicon monoxide over the entire surface of an N-type silicon, germanium or silicon carbide wafer and subsequently oxidizing it to the dioxide, or forming a dioxide coating direct on the body if of silicon or silicon carbide by various oxidation techniques. Pairs of windows are cut in the oxide and boron diffused through from a gaseous mixture of boron trioxide or halide mixed with argon, helium or nitrogen at 900-1200 C. After 30 minutes the atmosphere is replaced by steam or oxygen to fill the windows with oxide. A new window is cut through this to expose part of each resulting type zone and phosphorus diffused in from phosphorus trioxide or pentoxide to form in each pair 2, 3 of P zones N zones 4, 16 and an overlying oxide layer. Windows are cut over each zone again by photolithographic and etching techniques and vapour deposited ohmic contacts 5, 6, 7, 8, 18 alloyed in. All of these may be of aluminium if the N zone surfaces are sufficiently heavily doped, otherwise contacts to N zones are of goldantimony. After thermocompression bonding a wire to each contact the wafer is subdivided into single five zone units. Four zone switches are formed by omitting zone 17 and its contact. A multiple assembly of devices of this type useful as a data store or crossbar switching system is made by performing the diffusion steps on a series of strip-like N-type zones 19, 20, 21 (Fig. 5) in a P-type wafer thus providing electrical isolation between devices in adjacent strips. The devices are interconnected as shown by evaporated aluminium tracks on the oxide layer. At crossover points an oxide layer is provided between the tracks or one of them is continued through an N-type inclusion formed under the oxide.

Title: Electro-optical modulator
Inventor: EAGLESFIELD CHARLES CECIL
IPC: G02F1/03
Filed: 1967-10-12
Abstract: 1,143,040. Light modulators. STANDARD TELEPHONES & CABLES Ltd. 12 Oct., 1967, No. 46532/67. Heading H4F. An electro-optic modulator or deflector includes a stack of electro-optic crystal plates, the fast axis of alternate plates being aligned with the retard axis of the intervening plates, the arrangement being such that when a voltage is applied in opposite directions across adjacent plates the electro-optical effects of the plates are additive. The plates comprise Z-cut plates of KDP-ADP type crystals e.g. KDP or its isomorphs KD 2 PO 4  KH 2 AsO 4  or RbH 2 AsO 4  or ADP. In the embodiments described each plate is cut so that its major surface lies in the plane formed by the X and Y axes of the crystal, and is square with the X and Y axes forming the diagonals, Fig. la. The light beam and the electric field are applied to coincide with the Z-axis (which is normal to the major surface), the retard axis X<SP>1</SP> and fast axis Y<SP>1</SP> being at 45 degrees to the X and Y axes. The electrodes on the major surfaces of each plate comprise silvered annular recesses 2 and 2<SP>1</SP> having tails 3A and 3A<SP>1</SP>, the light beam being directed through the central portion 4. To ensure that the fast axis Y<SP>1</SP> of alternate plates are aligned with the retard axis X<SP>1</SP> of intervening plates, each alternate plate may be constructed as shown in Fig. lb, alternatively all the plates may be made with two tails on the lower surface parallel to the fast axis, Fig. 3, not shown, a stack of such plates arranged according to the invention being shown in Fig. 4. No insulation is required between the plates since the direction of the field is reversed in each plate, i.e. adjacent electrodes of successive plates are at the same polarity and may be electrically connected. Semi-transparent electrodes may be used instead of annular electrodes. The stack may include a quarterwave plate and a polarizer at the input light end. By placing a crossed polarizer at the other end the device comprises a modulator. When the additive result of the applied voltage is equivalent to a half-wave voltage, the switching of the polarization may be used to cause deflection of the light beam if the crossed polarizer is replaced by a Wollaston prism.

A method of producing filament yarns of acrylic polymers comprises extruding a solution of acrylic polymers containing at least 85% acrylonitrile into a liquid coagulating bath to form a plurality of filament yarns through a number of spinnerets mounted in spaced relation, washing the gelled filament yarns thus formed, subsequently stretching the same to a length at least four times the original length thereof, applying to the stretched filament yarns while still in the wet and swollen state less than 2% of their dry weight of a first agent as herein defined, thereafter subjecting the filament yarns to simultaneous shrinking and drying treatment to shrink the yarns by 5 to 20% along the fibre axis while maintaining the filament yarns in spaced relation by guiding the same with combs through a drier at a temperature of from 100 to 200 C., feeding the filament yarns into a sizing bath to apply to the filament yarns less than 10% of their dry weight of a sizing agent, drying the filament yarns under tension and at a temperature lower than that of the previous drying and shrinking treatment to stretch the same by up to 10% but less than the extent of the aforesaid shrinkage, and subsequently applying a finish oil and taking up the filament yarns. The first agent may be an oiling agent containing a surfactant, which is preferably non-ionic. Preferred surfactants include polyoxyethylene alkyl-ethers, polyoxyethylene alkyl phenols, polyoxyethylene alkyl esters and sorbitan alkyl esters. Desirably, the oiling agent has a melting point below 100 C. Alternatively the first agent may be a sizing agent, suitably polyvinyl alcohol, polyacrylic acid salts and copolymers of vinyl acetate and maleic acid, or may be a mixture of an oiling agent and a sizing agent. Said first agent may be in the form of an aqueous emulsion and/or an aqueous solution. The shrinking and drying treatment is preferably applied at a temperature within the range 110 C. to 180 C., and the sizing agent applied to the filament yarns after the shrinking and drying treatment is suitably selected from polyvinyl alcohol, polyacrylic acid salts and copolymers of vinyl acetate and maleic acid. In a preferred method, the said treatments of the filament yarns are performed while moving a number of such yarns in parallel to one another with small spacing therebetween, from the extrusion to the take up. Examples are given.
