Title: Electrochemical separation of gases
IPC: C25B1/02
Filed: 1967-02-01
Abstract: 1,143,305. Separating mixtures of gases by electrolysis. ALLIS-CHALMERS MFG. CO. Feb. 1, 1967 [Feb.2, 1966], No.4922/67. Heading C7B. An electro-chemically activable gas such as oxygen or hydrogen is separated from a gaseous mixture containing the gas e.g. air in an electrolytic cell 10 comprising a pair of gas permeable electrodes, activation electrode (cathode) 11 and regeneration electrode (anode) 12, spaced apart by an electrolyte matrix 13, such as spun fibrous asbestos or polypropylene, saturated with an aqueous electrolyte such as alkali metal hydroxide e . g. KOH or sulphuric acid, and connected to a D.C. source 14. The mixture is circulated through a gas reactant compartment 16 across the surface of the activation electrode 11 provided with a gas activating catalyst, e. g. comprising porous Ag, on which the gas reacts to form a solvated compound which passes through the electrolyte to the regeneration electrode 12, e. g. comprising porous Ni or C catalyzed by Fe, Co, Pd and/or Pt, where the gas is regenerated with water in a collecting compartment 17. Fresh electrolyte 18 is circulated through the collecting compartment 17 and the regenerated gas subsequently removed, e . g . by recirculating the electrolyte 18 through a separator 22 using pump 21 and conduits 23-25, and the mixture is supplied into the compartment 16 under sufficient pressure e. g. by a compressor 30 to prevent leakage of electrolyte through the porous activation electrode 11. A pressure differential of 5-15 psi is preferably maintained across the cell by monitoring a control valve 31 on conduit 19 connecting the compressor to the compartment 16 by a conduit 28. Preferably the concentration of the electrolyte 18 is readjusted prior to recirculation by heating the electrolyte to vaporize excess water. Oxygen maybe separated from compressed air distributed by suitable manifolds to a plurality of, e.g. 15, individual cells in a D.C. powered multiple cell assembly (see Fig.2, not shown).

Title: Absorption-refrigerating unit with pressure-equalising gas
IPC: F25B33/00
Filed: 1959-02-12
Abstract: 858,922. Refrigerating. STIERLIN, H. Feb. 12, 1959 [Feb. 12, 1958], No. 4968/59. Class 29 In a system of the continuous cycle inert gas type having a pumping chamber 6 heated by hot solution in a boiler 2, the pump riser tube 8 passes through the solution and the space therein is thermally insulated around its entire periphery and along its whole length from the space in the boiler. As shown in Fig. 5, tube 8 is made of thermally insulating material but it may be made of thin metal surrounded by an evacuated or gasfilled jacket. As shown in Fig. 7, the jacket 32 opens at its lower end into chamber 6 so that, in operation, it fills with vapour or inert gas to give the insulating effect. The upper part of jacket 32 may be narrower than the lower part, the jacket being spaced from tube 8 by a helical wire. The upper part of the liquid in the boiler acts as an analyser.

Title: Line tracing apparatus
IPC: G06F3/041
Filed: 1972-02-02
Abstract: 1341676 Digitizing lines INSTRONICS Ltd 2 Feb 1972 [2 Feb 1971] 4985/72 Heading G4H [Also in Division G1] In apparatus for providing the X and Y co-ordinates of points on a line traced on a transparent sheet (5, Fig. 1, not shown) supported on a table (3), as an operator moves an index (7) over the line, a slider (41, Fig. 2, not shown) is driven by X and Y servomotors 95, 63 (Fig. 8) to follow the index, the driving drums of the motors also driving X and Y encoders 91, 67. As described a rod (25, Fig. 2, not shown) is attached by screw threaded belts to brackets mounted on a frame attached to the table. An arm (31) is slidably mounted on the rod and  carries the slider which has rollers to locate it accurately on the arm. Mounted on the slider are two pairs of coils 113, 115 (Fig. 8) energized by an oscillator 121 which as the operator moves the index over the line to be traced induce a phase significant signal in a pick-up coil 125 in the index. The signal from the pick-up coil is fed to servo control systems controlling the X and Y servomotors 95, 63 driving the slider so that it follows the index. The servo systems comprise X and Y phase amplitude detectors 129, 131 each fed with the signal fed to one of the pairs of coils and the pick-up coil output. The detector outputs are fed together with the outputs of the X and Y encoders to amplifiers 133, 135 controlling the servomotors 95, 63. The slider is moved along the arm by the driving drum (61, Fig. 6, not shown) of the Y servomotor (63) by a steel cable (51) which is fixed at its end points (51A, 51B) and extends round fixed pulleys (53, 57, 59, 69, 71, 75) as well as pulleys (55, 73) mounted on the slider. The arm is moved along the rod by the driving drum (93, Fig. 7, not shown) of the Y servomotor (95) driving an endless steel cable (81) to which the arm is anchored at its end points. The slider also carries an optical system for projecting the image of a graticule on to the transparent sheet. In one embodiment (Fig. 10, not shown) this comprises a horizontal tube having a light source, graticule and lens system and an inclined mirror to direct the image of the graticule output on to the sheet. In another embodiment (Fig. 11, not shown) the tube is vertical. Read out of the states of the encoders is effected each time the operator operates a switch button (13, Fig. 1, not shown).

Filed: 1927-02-26
Abstract: 283,010. Smith, W. S., and Shuter, A. D. Feb. 26, 1927. Tension indicators for ropes &c.-The riding or measuring sheave over which is passed a submarine cable which is being laid, picked up, or held, is mounted so that its weight does not influence the action of the dynamometer, whilst the loading means of the dynamometer is not substantially affected by gravity. The pedestal 4 carries a pivot 3 for a lever 2 at one end of which is pivoted the sheave 1. whilst the other carries a counterweight 5 thus forming a balanced system. The end of the lever engages with a plunger 6 in a cylinder 7 containing fluid the pressure of which, and hence the tension on the rope, is indicated by a gauge 9. In a modifica.tion Fig. 3, the sheave is carried on a lever 10 the pivot 11 of which is supported vertically above the centre of gravity of the sheave. The lower end of the lever engages a ram 12 in a cylinder 13 containing fluid operating a gauge 14. In order to control the tension on the cable, the cylinder 13 communicates through a cock 20 and pipe 15 with a cylinder 16 of smaller bore the plunger 17 of which is suitably connected to the clutch or brake controlling the paying-out or picking-up gear of the cable. The tension of the loading spring 18 may be adjusted by a screw 19.

Abstract: 717,140. Socks. TENOVA, Ltd. Feb. 27, 1953, No. 5571/53. Class 141 [Also in Group VIII] A self - supporting sock of the kind having an elastic garter band at its upper edge and with the normal calf portion cut away is characterized in that the garter band is free to stretch evenly and to a substantial extent over its whole circumference relatively to the knitted upper portion of the sock. As shown the garter band 22 is attached to the upper section 1 of the sock by lock stitching 25, the upwardly convergent edges of the section 1 forming the marginal edges 6 of the cut-out. The unstretched length of the elastic band which is attached to the upper edge of the section 1 is less than the length of such edge to allow stretching in wear. In a modification, the upper section of a seamless sock has an integrally knitted elastic portion of substantially less diameter than the remainder of the section. The cut-out is formed, in this case, by the removal of some of the sock material with the aid of a template.
