Abstract: 1,250,259. Electro-chemical cells. WESTINGHOUSE ELECTRIC CORP. Oct. 15, 1969 [Nov. 5, 1968], No. 50664/69. Heading GIN. An electro-chemical cell 1 comprises first and second electrodes 12, 14 disposed on opposed surfaces of a tubular, solid electrolyte member 10, a voltage source 24 and an ammeter 28. In use, a reference gas of known oxygen concentration is flowed through the tube while a sample gas is flowed along its external surface, a predetermined voltage being applied from the source so as to establish diffusion limited current operation when, it is stated, the current flowing between the electrodes is a function of the amount of oxygen present in the sample gas. To increase the ionic conductivity of the electrolyte an electrical heater is disposed about it and set to give an operating temperature in the range 600‹ C. to 1000‹C. The electrolyte is a solid solution of zirconium oxide and one or more of the oxides of borium, calcium lanthanum, scondium, strontium or yttrium. The electrodes are platinum and made porous to oxygen. In an alternative embodiment, Fig. 4 (not shown) separate gas chambers for the reference (52) and the sample (50) are joined by a solid zirconium oxide electrolyte (32) bearing, on opposite faces, platinum electrodes (34, 36), the former in the sample gas chamber and the latter in the reference gas chamber. A further modification dispenses with a separate reference gas, sample gas flowing between chambers (50) and (52) by way of passages (60).

Abstract: 1,251,058. Degaussing cathode ray tube apparatus. TEXAS INSTRUMENTS Inc. 3 Dec., 1968 [8 Dec., 1967], No. 57357/68. Heading H4T. [Also in Division H1] A degaussing circuit for a colour television comprises a thermal relay 20 connected across a degaussing coil 168. When manual switch 156 is closed the coil 168 and the resistor-heater 114 of the relay are energized. The temperature coefficient of resistance gives a current-time characteristic having a sharp anomaly point, the current decaying after a few seconds to a very low value. At a preselected temperature, relay contacts 72 close, by-passing the degaussing coil. The resistor-heater remains energized and at a constant temperature, thus keeping the contacts closed and the coil by-passed. The degaussing circuit may alternatively be on the secondary side of the transformer supply to the receiver, Fig. 8 (not shown). The degaussing is applicable to any receiver parts of magnetically permeable materials e.g. chassis members or picture tube shadow masks. Reference has been directed by the Comptroller to Specification 1,156,810.

Abstract: 1,252,670. Stretching coated fibres. BEAUNIT CORP. 5 Sept., 1969 [11 Sept., 1968], No. 44163/69. Heading B5B. [Also in Divisions B2 and D1] A polyester fibre is coated with a copolyester comprising 5 to 80% by weight of polyester units chemically identical with the fibre and 95 to 20% by weight of polyester units derived from a polyoxyalkylene glycol, heated to bond the coating to the fibre, washed with an innocuous liquid and dried.  The polyester fibres may be in the form of yarn, filaments, staple fibre or fabric but the process is particularly applicable to the treating of undrawn fibres, especially of ployethylene terephthalate and poly(1,4-bis-methylene cyclohexane terephthalate). In a process for treating undrawn fibres, the copolyester is applied either as a solution in a solvent which is innocuous to the fibre or as a dispersion in a non-solvent innocuous to the fibre, especially an aqueous dispersion.  In a preferred embodiment, an undrawn polyester fibre is wetted with an aqueous dispersion of 1-20% by weight of copolyester polymer, having 5-80% by weight of polyester units identical to those in the fibre and 95-20% by weight of polyoxyalkylene units of 300- 15,000 molecular weight, to provide a wet pickup on the fibre of 5-100%. The wetted fibre is then drawn at 50-260 C. to crystallize the fibre, using draw ratios of from 2-10. This also dilutes and fixes the copolyester on the fibre surfaces and provides 2 Î 10<SP>-8</SP> to 4 Î 10<SP>-5</SP> grams of polyoxyalkylene units per square cm. of the drawn fibre surface. Next, the drawn fibre is heated to relaxation temperatures to relax the fibre and further fix copolyester to the surface; the relaxed fibre is then washed substantially free of unfixed copolyester. Optionally, a friction agent is added and excess liquids are then removed from the fibre, after which the fibre is heated and dried, further relaxed and annealed to refix loosened copolyester.

Abstract: 1,257,468. Building pneumatic tyres. DUNLOP HOLDINGS Ltd. 6 March, 1969 [9 March, 1968], No. 11607/68. Heading B7C. [Also in Division G3] A tyre building apparatus, including a drum and associated tools, as disclosed in Specifications 1,244,164 and 1,214,628 is associated with a positional control system for controlling the position and attitude of spinning tools in accordance with a programme. As shown, spinning tools 1, 2 are positioned relative to a tyre building drum 7 by a leadscrew 6 driven by a motor 8. A multi-channel digitizer 3 is driven by the motor 8 and gives an output F on one of ten channels to a comparator 5, the other input C of which is derived from the columns of a plug-board 4 the rows of which are set up in dependence on the steps of a positioning programme for the tools. When the actual position signal is less than that set on the plugboard the comparator gives an L output to switch on the motor and drive the tools apart, conversely, an H output causes the tools to be brought together. At balance, a ring counter 9 is initiated, by an output B of the comparator, and steps the plugboard to the next row and sends a pulse signal to electro-pneumatic valves 10, connected to the spinning tools, setting the attitude or pressure of the tools to that required throughout the programme step. In a modification, the programme plug-board is extended by employing two further plugboards one of which is stepped by the ring- counter and the other set by a manual programme selector switch which are interconnected to the plug-board 4 by a plurality of gating circuits. In an additional modification, three digitizers are geared in cascade to give increased accuracy of position indication. The output of each digitizer is compared in a comparator with the output of a corresponding plug-board and the outputs of the three comparators summated to derive the control signals H, L, B. Further a plug-board is used to enable a rapid change of programme for valves 10. The digitizers can be decimal or binary-coded.

Abstract: 1,258,141. Making tubes; extruding; drawing; welding by pressure. COMITATO NAZIONALE PER L'ENERGIA NUCLEARE. 1 Jan., 1969 [3 Jan., 1968], No. 69/69. Headings B3A, B3P and B3R. A tubular joint formed by metallurgical bonding is achieved by extruding a billet composed of at least two coaxial annular metallic masses 1, 2 in a vacuum tight case 3 into a tube 6 which is reduced at at least one end and then machined to render the inside and outside diameter consistent. The billet is made of zirconium or its alloys 1 and stainless steel 2 formed with ribs 5 to break the oxide layer of the zirconium. The billet is enclosed in a vacuum retaining case of malleable iron. After degreasing or chemical cleaning the billet is heated to 800‹ to 900‹ C. and extruded into a preferably circular tube 6 although the tube may be square or rectangular. At least one end of the extruded tube 6 is reduced by pushing into a die 11, Fig. 7. The reduction may alternatively be achieved by swaging, interrupted drawing or interrupted extrusion. The reduction is performed with the tube heated to 200‹ to 450‹ C. The deformed tube is then machined on a lathe so that the final inner diameter is at least equal to that of the undeformed portion of the tube and the final outer diameter is at most equal to the outer diameter of the reduced portion. If a double joint is formed the outer tube parts (16), (16<SP>1</SP>), Fig. 11 (not shown), are zirconium and the central tube part 15 is stainless steel. To reduce waste material the part of the billet which forms the central part (15) may be soft iron and thus can be removed chemically instead of machining. Examples of billet sizes, reduction rates, joint tensile-stress &c. are given.

Abstract: 1,258,304. Toe pieces for ski bindings. H. MARKER. 18 March, 1969 [19 March, 1968], No. 14212/69. Heading A6D. In a toe-piece for a safety ski-binding the toe-holder member 6 is connected to the baseplate 1 by a carrier 4. The base-plate is formed with screw holes 2 for attaching it to the ski and has a dovetail-shaped guide strip 3 which engages in a similarly shaped recess in the carrier 4. The carrier also has a dovetailshaped guide track 5 which engages in a recess in the holder member 6 and is forwardly curved from the centre to the edge. The toeholder 7 is connected by a screw 8 to the toeholder member 6, the vertical slot 9 in the toeholder enabling adjustment for soles of different thicknesses. The carrier 4 contains a pin 10 formed with a conical top 11 which fits into a recess in the toe-holder member 6, the lower end bearing on the top of the base plate. The guide track 3 has two holes 12 (not shown) symmetrically arranged with respect to the central longitudinal axis of the toe-piece into which the lower end of the pin can engage when the carrier has been sufficiently transversely displaced relative to the base plate. A weak spring 13 is fitted around the pin bearing on the conical top and a shoulder of the bore. Another spring holds the carrier 4 in its central position on the base plate and serves to return the carrier to this position when, it has been displaced. If a force is sufficiently large to displace the toe-holder and carrier the pin 10 engages in one of the holes 12 and the carrier is locked to the base plate and the toe-holder will move on along the guide track 5 of the carrier, thus releasing the toe portion of the boot. In a second embodiment the toe-holder member and carrier are pivoted to the base plate by a pivot pin. The locking device comprises a hole in the carrier which carries two balls. In a third embodiment the toe-holder is formed of two parts which are symmetrical about the central longitudinal line.
