Title: Improvements in or relating to apparatus for delivering electric impulses from a source of current supply
IPC: A61C5/68
Filed: 1929-12-18
Abstract: 344,103. Inertia make and - break switches; retractive switches. THEW, W., 14, Upper Wimpole Street, London. Dec. 18, 1929, No. 38785. [Class 38 (v).] A device for producing a series of current impulses which may be employed for example in conjunction with a dental or surgical chisel of the type described in Specification 316,478, [Class 124, Stone &c.], comprises a hinged casing B adapted to be depressed by the foot to bring the contacts K<4> into engagement with the inclined end of a relatively fixed contact blade K. The movement of the casing sets in vibration a loaded contact blade F fixed at one end beneath a block E and carrying a weight F<1> at its other end and thus a series of current interruptions are produced between a contact G on the blade and a contact block G<1> fixed within the casing the contacts G, G<1> being in series with contacts K, K<4>. In the return movement of the casing after release by the foot the current impulses in the controlled circuit occur as this circuit is broken, at contacts K, K4. In an alternative form of switch the contact on the vibratory member is below and normally out of engagement with the fixed contact G1. In this form a single current impulse may be produced by first inverting the switch and then bringing contacts K, K<4> in together. The period of oscillation may be varied by the provision of an adjustable weight which may be renewed at varying positions along the spring F.

Title: Improvements in the treatment of napped acrylonitrile polymer fabrics
IPC: D06M13/248
Filed: 1962-10-22
Abstract: Woven, non-woven and knitted fabrics composed of a polymer containing at least 80% by weight of acrylonitrile having a napped pile are treated with an aqueous solution of dimethyl acetamide, dimethyl formamide or dimethyl sulphoxide dried to evaporate the water from the solution and to set, cure and concentrate the stabilizing agent at the intersections of the fibres in the nap to form a durable band between and among them to prevent pilling and shedding of the nap. The aqueous solution which may contain 0.05-50% by weight of the dimethyl formamide, dimethyl acetamide or dimethyl sulphoxide may be applied to the fabric by padding or spraying and the fabric may then be dried and cured by heating at a temperature of 240 DEG -300 DEG F. for 5-60 minutes.  The treating solution may also contain antistatic agents, e.g. polyamine resins formed by cross linking diethylene triamine with polyethylene glycol diiodide and epoxy resins, softeners, e.g. silicones, polybutadiene, or water repellent agents, e.g. melamine derivatives.  The fabrics may be made from polyacrylonitrile, copolymers containing at least 80% by weight of acrylonitrile, or a blend comprising polyacrylonitrile or copolymers comprising acrylonitrile with 2-50% by weight of another polymeric material the blend having an overall polymerized acrylonitrile content of at least 80% by weight.  The acrylonitrile may be copolymerized with acrylic, a -chloroacrylic or methacrylic acid, methyl, ethyl, butyl, methoxy methyl or b  chloro ethyl methacrylate, acrylate or a -chloroacrylate, vinyl chloride, fluoride or bromide, vinylidiene chloride, 1-chloro-1-bromo-ethylene, methacrylonitrile, acrylamide, methacrylamide, a  chloroacrylamide, methylvinyl ketone, vinylacetate, chloracetate, propionate or stearate, N-vinylsebacimide, N-vinylsuccinimide, methylene malenic esters, itacenic acid and esters thereof, N-vinyl carbozole, vinyl furane, alkyl vinyl esters, vinyl-sulphonic acid, diethylcitaconate, diethylmesaconate, styrene, vinylnaphthalene, vinylpyridines, 1 vinylimidazole and alkyl substituted 1-vinyl-imidazoles.

Filed: 1973-08-24
Abstract: 1435115 Fuel elements EXXON NUCLEAR CO Inc 24 Aug 1973 [31 Aug 1972] 40180/73 Heading G6C Mixing vanes are so arranged on certain sections of reactor fuel assembly spacer grids to provide a vortex flow of coolant about each intersection of the fuel assemblies in the reactor core. This flow produces a mass transfer of coolant between the assemblies to effect temperature averaging between high and low temperature regions of adjacent assemblies. As shown in Fig. 2, triangular-shaped vanes 107 are mounted at the intersections of the interlaced straps 108 of a spacer grid 104 and cantilevered above the openings 106 so that coolant flowing up through the springs 106 contacts the vanes 107 and is caused to move laterally. Each vane 107 has a gradual concave curvature extending from the straps 108 and is formed with two arcuate side portions. The vanes 107 are placed in specific locations to develop vortex-shaped coolant flow patterns that span at least three openings 106, and more preferably have a diameter about one-half the width of a fuel assembly (as shown in Fig. 3). A preferred arrangement of the vanes 107 in a grouping of four adjacent fuel assemblies is shown, this arrangement producing vortex-shaped coolant flow patterns 109 and 110, the patterns 109 being centered about the middle of each spacer grid cross-section while the patterns 110 are centered about the points 111 where four adjacent fuel assemblies are grouped. The vanes 107 are mounted so that adjacent flow patterns do not run counter to one another and thus cause breakdown of the patterns, but instead co-operate with one another in maintaining the flow patterns established.

A fluid actuated motor-pump assembly 22 for a deep well is run into and out of the well through the supply tubing 30 by application of hydraulic pressure introduced into the tubing 30 above a packer 82 and below the assembly through the production tubing 34. The assembly comprises a motor section 94, an upper pump section 122 and a lower pump section 124 each pump section comprising a double acting piston. The bottom hole assembly 20 comprises spaced sealing collars 36, 42, 50, 56 interconnecting the supply tubing 30, the motor tube 40 and the pump tubes 48, 54. Seals, e.g. 98, 164, in the motor-pump assembly co-operate with the sealing collars 36, 42, 50, 56 to form passages which inter-connect various ports, e.g. production fluid inlet and outlet ports, in the motorpump assembly and connect the appropriate passages to the main outlet 46 and exhaust fluid out 32. To permit assembly, the lower pipe 252 of the outlet 46 comprises (Fig. 5) an upper and lower section 258, 260 connected together by a telescopic joint 262 which is tightened to tension the sections 258, 260 to prevent bowing of the tube 54. The various seals, e.g. 98, 164, are only pressed into sealing engagement with the corresponding component of the bottom hole assembly 20 when the pump assembly 22 is in operative position. Considering the seal 98 shown in Fig. 10: it is disposed between a rigid fixed sleeve 198 and an upper rigid differential area sleeve 202 which is axially slidable and has a small lower area 208 engaging the seal, a large upper area 210 exposed to operating fluid pressure, and an annular surface 212 exposed to production fluid inlet pressure, i.e. the seal is subjected to pressure in excess of the difference between the pressures which the seal separates. Preferably the seals have steel cores to resist blowing out of their grooves.

As shown a motor 5 drives a sectored shutter 6, a film feeding pawl carried on a plate 7 and has a shaft 20 extending to drive sprocket 12. The sprockets 11, 12 are connected by an intermediate gear 22, so that the sprocket 11 is powered from the shaft. Film 3 passes from cartridge 13 between sprocket 11 and roller 15, is driven intermittently through a gate having fixed 16 and retractable 8 plates, forms a loop L, passes over a constant speed roller 9, driven by a flywheel, at which point a sound track is optically recorded by head 17, passes over tension roller 37 and returns to the cartridge 13 between the sprocket 12 and roller 15. The sprockets 11, 12 by being driven at a constant speed only permit a given length of film to remain outside the cartridge during filming. To load the camera a knob 15' is moved from the position in Fig. 3 to that in Fig. 4. This pivots lever 34 about axis 35 and protrusions 43, 44 bear against surfaces 39', 40' thereby causing levers 39, 40 to move relative to each other against the action of spring 42. This movement of the knob 15' withdraws rollers 14, 15, 37 and retracts the back plate 8 of the gate. The recording head 17 includes a luminescent diode, lenses to focus the light beam therefrom on the film 3 and slits to regulate the dimensions of the beam. The camera also includes an amplifier which provides a signal to the diode, from a microphone or tape recorder, to control its luminance. The amplifier may include a thermistor to give a temperatureindependent response and be arranged to provide monitoring signals from various points in its circuitry.

Title: Improvements in or relating to the spinning and drawing of threads manufactured from synthetic linear poly-condensation products
IPC: D02J1/22
Filed: 1961-11-16
Abstract: Synthetic linear polycondensation products are melt spun, and the spun threads are wetted, e.g. with an aqueous emulsion of a finishing agent, and wound into a thread roll which is transferred to an envelope or container serving to protect the thread from the atmosphere, until the thread roll is subsequently unwound <PICT:0926596/IV(a)/1> <PICT:0926596/IV(a)/2> from an envelope or container on a drawtwisting machine.  A polyethylene bag may be used as a container.  Preferably the thread roll is kept in a container provided with a thread discharge opening, especially a thread guiding eyelet, until and during unwinding prior to drawing, the thread discharge opening being closed during storage and transport.  As shown, a thread roll or bobbin 11 may be stored in a box 18 fitted with conical lid 19 having a thread guiding eyelet 20.  Unwinding of the thread is facilitated by the thread guiding disc 21, secured by clamp 22 to cylindrical core 24, fixed to the base 23.  In the subsequent draw-twisting operation, the thread 9 passes over pin 10, via the traversing thread guide 14 and around pressure roller 12, feed roller 8 and draw pins 15 to draw godet 16 and associated guide roller 17 and thence via eyelet 7 to the ring-twister 3.  In an example a polyamino caproic acid filament is melt-spun, wetted with an aqueous emulsion of a finishing agent, wound up and stored in a box prior to subsequent draw-twisting from the box at 20 DEG C. and 65% relative humidity.  The thread was drawn 3,12 times its original length at 380 m./min. Thread so treated shows fewer faults per package than that processed by conventional methods.

Abstract: 1387227 Piecing-up yarns; hand tools HEBERLEIN & CO A G 5 Sept 1973 [14 Sept 1972] 41810/73 Headings D1F and D1W In the operation of portable apparatus for welding synthetic yarns, ends 11 and 12 to be joined are passed between blade springs 1 and 2. Movement of an operating lever 14 and consequent movement of an arm 3 (about a pivot 13 against the bias of a spring 8) clamps the yarns and closes a gripper element 2a with ends 11, 12, caught and positioned by a hook therein. On further movement of arms 3, element 2a approaches a heating element 4 which glows as a switch 6 operates to connect a battery 7 thereto. An eccentrically mounted, and therefore adjustable, stop 5 limits further movement of the blade springs in the same direction. When contact of ends 11, 12, with hot element 4 has fused them together, lever 14 is partly released so that arm 3 (under bias of spring 8) opens switch 6 but joined ends 11, 12, are held until the joint has cooled. Complete release of lever 14 frees the welded ends and positions the apparatus components in readiness for another welding operation.
