Filed: 1962-08-20
Abstract: Napped fabrics of fibres made of a polymer containing at least 80% by weight of polymerized acrylonitrile are impregnated with a solution of zinc fluoborate and then edged to prevent matting, pilling and shedding of the nap under normal laundering and wearing conditions. Prior to napping the fabric may be treated with a silicone resin and a polyamine resin, e.g. dimethylene triamine crosslinked with polyethylene glycol di-iodide or and epoxy resin.  A silicone resin may also be applied to the napped fabric together with the zinc fluoborate.  Aqueous solutions, which may be applied to the fabrics by padding or spraying, having a zinc fluoborate concentration of 0.35-10% by weight may be used and after treatment the fabrics may be heated for 5-15 minutes at a temperature of 240 DEG -300 DEG F.  The softness of the treated fabrics may be improved by passing them through a cold calender.  Suitable silicone resins are those of the formula <FORM:0984154/D1-D2/1> in which R is any monovalent hydrocarbon radical, any hydroxylated monovalent hydrocarbon radical or hydrogen and n is an integer of 1-3.  Woven, non-woven or knitted fabrics made from fibres comprising polyacrylonitrile, copolymers of acrylonitrile with other monomers containing >C = C< linkages or blends of acrylonitrile polymers or copolymers having an overall acrylonitrile content of at 80% by weight may be treated.

Abstract: 1,117,107. Cooling electric rotors. TSENTRALNOE KONSTRUKTORSKOE BJURO. 27 July, 1965, No. 31959/65. Heading H2A. In a gas cooled rotor e.g. of an electric generator, having intercoil insulation cleats 2 and spacers 1 arranged in the end windings the cooling gas is caused to pass along helical passages 6, 7 which are partly bounded by the coil conductors and which do not communicate with one another along their lengths. Cooling gas enters intake 8 and splits into two streams. One passes through the passages 6 in the spacers 1 to cool the arched sides of the conductors 10, 11 and enters the air gap of the generator via passages 12 made in a central part of the rotor. The other stream flows through the passages 7 in the cleats 2 for cooling along the length of the conductors 10, 11 and out into the air gap via gaps 16 between the binding 15 and end of rotor 17. In an alternative arrangement (Fig. 2, not shown), the cooling gas flows in separate staggered helical channels forming V-, N- and W-shaped patterns when viewed from the sides of the copper conductors. Communicating passages are provided at the top and bottom of the conductors by grooves (24) in the insulation of the cleats and spacers.

Abstract: 604,701. Dictation machines. DOUGLAS & CO., Ltd., C. E., and SCOTT, P. B. Nov. 30, 1945, No. 32346. [Class 40 (ii)] In a dictation-machine using cylindrica records, the mechanism for lowering and lifting the stylus to and from the record has means associated with it whereby back-spacing or forward-spacing is automatically effected according to whether it is desired to play back the last few words of the recording or to continue recording. A lead-screw k passes through a sleeve e having eccentric members d<SP>1</SP>, d<SP>2</SP> on which the carriage b is mounted. The said carriage b has extending arms a<SP>1</SP>, a<SP>2</SP> between which the transducer c is suspended. The arm a<SP>2</SP> is connected to a steady-bar i by a mechanical linkage which permits the transducer c to be lowered when the eccentric members d<SP>1</SP>, d2, controlled by the knurled ring f, are rotated in either direction, a clockwise rotation bringing the reproducing point c<SP>2</SP> in contact with the record; and a counter-clockwise rotation the cutting tool c<SP>1</SP>. The eccentric member d<SP>1</SP> is provided with a staggered groove g into which a spring-loaded ball h in the carriage b rides and serves to advance or retard the carriage b according to the direction of rotation of the knurled ring f. Traverse of the sleeve e and carriage b, on the. lead-screw k, is effected by a half-nut k<SP>1</SP> which rests in an opening in the sleeve e and is pressed into contact with the leadscrew k by a leaf-spring k<SP>2</SP>, except in the neutral mid-way position, where a projection r on a ring l coupled to the knurled ring f, pushes the half-nut out of engagement with the lead-screw k. The drive to the recording cylinder is effected through a magnetically-operated clutch, which when de-energized permits a brake to be automatically applied.

Abstract: 662,757. Cathode-ray tubes. RADIO CORPORATION OF AMERICA. Dec. 15, 1948 [Dec. 19, 1947], No. 32476/48. Class 39 (i). The emissive surface of the first dynode of a low-velocity scanning type of image tube is convexly curved towards the impinging electrons, the radius of curvature being small enough to give uniform collection of secondary electrons by the collector and large enough so that substantially no tangents to the emissive surface will intersect any part of the collector electrode. The electron gun structure of the tube comprises a cathode 26, control grid 28, accelerating electrode 30 and limiting apertures electrodes 32, 34, and provides a low velocity beam which is focused by a wall coating and coil, and scanned on to a conducting glass target, the beam being reflected in accordance with the charge image on the target. A fine mesh collector screen is mounted close to and on the image side of the glass target. The convexly-curved electrode 32 is the first stage of a multiplier section and is formed of a silver magnesium sheet to provide a dynode surface. The multiplier has further stages 44, 46, 48, 52 each maintained at progressively higher potentials, with a final collecting stage 50 at the highest potential. Each stage 44, 46, 48 consists of a thirty-two blade pin-wheel of silver magnesium alloy, the blades of consecutive pin-wheels being formed in an opposite sense and each stage has a 90 per cent transmission screen 51, 53, 55 preventing the suppression of the secondaries to be collected. The collector 50 comprises an annular ring with a metal screen stretched across it. A persuader electrode 42 encloses the first stage 32 and is slightly more negative than the enclosed stage, giving a practically field-free space above the surface of the anode. A finemesh screen is mounted close to the glass target on the photo-cathode side and is several volts positive relative to the equilibrium potential of the target collecting the secondaries emitted therefrom. The dynode surface 32 is located in the weak fringe field of the solenoid 16 (not shown).

Title: Method and apparatus for the purification treatment of waste liquid by aeration
IPC: C02F3/20
Filed: 1960-09-22
Abstract: <PICT:0965230/C1/1> A tank 1 has an influent feed conduit 2 and effluent discharge trough 3 provided at respective ends of the tank. Between these ends, the tank is functionally sub-divided by transverse walls 4, into a horizontal sequence of treatment zones Z1, Z2, Z3, and Z4, though in actual practice any number of such zones may be utilized.  The transverse walls 4 extend upwardly above the liquid level an their lower ends are spaced from the tank bottom to provide flow passage space allowing for flow of liquid both forwardly and rearwardly. They may be positioned differently or may be of adjustable height.  One way of achieving these oppositely directed flows is by the provision of a transverse diversion shelf 5 below each wall 4, which shelf is forwardly and downwardly inclined so as to provide a forward flow passage 6 above, and a rearward flow passage 7 below this shelf and may be movable.  Each of the treatment zones has an intermediate transverse vertical wall 8 substantially parallel to walls 4, and defining in each of the treatment zones an upflow section 9 for the liquid to ascend therein, and a downflow section 10 for the liquid to descend therein, such circulation about the intermediate wall 7 being induced and maintained by the provision in each of the upflow sections 9 of air-diffuser elements 11.  In the present example, the diffuser elements constitute a grid-like system of parallel air-diffuser tubes provided with suitably arranged air-jet openings.  Air is supplied to the diffuser elements through pipes leading down from the valve controlled air supply conduits 12. Figs. 7-12 (not shown) relate to treatments with primary and secondary clarifiers embodying additional features associated with the step-wise introduction of raw feed and/or return of activated sludge.
