Title: Improvements in or relating to the treatment of artificial filaments, threads, yarns, fabrics and the like
IPC: D06M13/188
Filed: 1934-02-28
Abstract: Artificial filaments, threads, yarns, fabrics, and the like are subjected to treatment with a solvent, swelling or softening agent, under such conditions that the agent does not completely penetrate the filaments and the like, and are then subjected to dyeing or other wet textile operation in rope or other folded form.  The action of the solvent or other agent is restricted so that it affects only the outer layers of the filaments or the like by applying small quantities, and/or by removing the agent from the filaments or the like, for example by washing, after a relatively short period of contact.  The process may be applied to the treatment of materials of regenerated cellulose or of cellulose derivatives.  Suitable solvents, swelling or softening agents are thiocyanates, caustic soda, zinc chloride, formic or acetic acid, lactic acid, methyl ethyl ketone, ethyl lactate, diethyl tartrate, ethers, glycol mono-acetate, methyl or ethyl glycol mono-acetate, tetrachlorethane, trichlorethylene, dichlorethylene, phenols, and ethyl alcohol.  The following examples are given of treatments applied before dyeing or other wet textile operation on the fabric in rope form: (1) and (2) cellulose acetate fabric is padded with a 10 per cent aqueous solution of formic acid, acetic acid, or ethylene glycol mono-acetate, given an air run for 30 seconds and washed; (3) cellulose acetate fabric is passed through a bath containing 80 per cent of tetrachlorethane and 20 per cent of toluene for about two minutes, washed with toluene, and dried.  Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, and 338,190, [all in Class 15 (ii)], are referred to.

Title: A method of securing components that are mounted on a circuit board
IPC: H05K13/04
Filed: 1965-02-15
Abstract: 1,032,143. Securing components to circuit boards; shearing. SCHNEIDER RADIO TELEVISION. Feb. 15, 1965 [Feb. 14, 1964], No. 6527/65. Addition to 1,018,278. Headings B3A and B3W. The method of the parent Specification of securing components to a circuit board by cutting and bending the wires which extend through holes in the circuit board is modified by cutting and bending the wires by a single working sweep of a tool 29 which extends between the arms of a U-shaped carrier member 27. The cutting tool 29 has a bevelled cutting edge and has ribs (not shown) on its upper surface which serve to bend the wires against the circuit board and to scrape the wires in preparation for soldering. The carrier 27 moves along guides 28 so that the cutting tool 29 passes between the circuit board (not shown) and a perforated plate 60 or 61, the wires passing through the perforations as in the parent Specification. During the cutting stroke the circuit board and plate 60 are held stationary, but on the return stroke the face 50 of a spring- loaded member 64 engages the plate 60 carrying the completed board to remove it, the plate 60 sliding along a guideway 32, and a nose 69 of the member 64 engages a groove 51 in the plate 61 to bring the plate 61 into operative position. During the cutting and bending operation the components are held against the circuit by an inflatable envelope (not shown).

Title: Infra-red heater
Inventor: GRUBB GEORGE RUDOLF
IPC: H05B3/44
Filed: 1968-02-09
Abstract: 1,273,343. Electric heating elements. HANOVIA LAMPS Ltd. 8 May, 1969 [9 Feb., 1968], No. 6575/68. Heading H5H. An infra-red heating element in an insulating e.g. quartz or silica, tube is manufactured by winding a length of wire of the desired resistance to form a helix, securing one end of the helix in position, stretching the helix sufficiently to separate the adjacent turns, oxidizing the stretched helix by heating it by passing a current therethrough, and then sealing the helix into the insulating tube. During the heating and stretching stage the helix may be mounted on a quartz rod or a plurality of helices may be on a bed formed by a plurality a parallel spaced tubes suspended from an insulating support by rigid iron wires passing through the tubes. In the latter case, each helix is supported by two adjacent tubes in the space between them. The helix or helices may be preheated during the initial stretching operation, prior to the main heating which produces the desired oxidation. Heating is effected by passing a current through the elements. The helix may be compressed to close its turns after heating. An element comprising two parallel helices may be made by benching a single helix at its centre. The wire coil may be supported on a quartz or silica tube.

Abstract: 777,809. Automatic circuit - breakers; switches held set and freed mechanically. CUTLER-HAMMER, Inc. March 12, 1953 [March 12, 1952], No. 6834/53. Class 38(5) The circuit-breaker disclosed in Specification 774,513 is modified by the addition of magnetic means to assist the thermal trip, the means comprising two complementary iron members 90, 91. Member 90 has a leg portion 90a connected by a curved portion 90b to a group of three downwardly projecting legs 92, 94a, 94b, the central longer leg 92 being welded to the leg 56x of the kick-out member. Member 91 has a pair of upwardly extending legs 102a, 102b, the upper end of each leg being formed with a pair of offset lugs 104, 106 which freely straddle the legs 94a, 94b whereby the latter serve as a pivot for the member 91. The lower end 96 of the member 91 has a pair of lugs 100 which engage in openings formed in the upper fold of the spring portion 60x of the kick-out member. When, on overload, the capsule of the power element 12 expands to move the projection 62x on the leg 54x of the kick-out member to the left, the end 96 of the member 91 is moved nearer the leg 90a of member 90. Also, the current flowing through element 12 induces a field in the members 90, 91 to attract the parts 90a, 96 to each other and thus assist the thermal tripping action. On short-circuit the breaker would be tripped by magnetic force alone Specification 656,721 also is referred to.

Filed: 1953-03-16
Abstract: A filter for use in the melt-spinning of synthetic linear polymers comprises a plurality of metal plates adjacent to one another and arranged in succession with respect to the general flow of the molten polymer, the surfaces of the <PICT:0735788/IV (a)/1> <PICT:0735788/IV (a)/2> plates having recesses therein to define narrow channels between contacting plates, the plates being further provided with through passages communicating with the recesses, and means for assembling the plates in juxtaposed contacting relationship, wherein the passages connect the narrow channels in staggered relationship to define a plurality of staggered paths of flow for the molten polymer. As shown in Fig. 1, each plate 14 is provided with a series of concentric circular grooves 16 of semi-circular cross-section on each face.  Corresponding grooves on opposite faces are connected by equidistant bores 15 having a diameter of from 0.2 to 0.5 mm. and a length of from 5 to 7 mm.  The plates are juxtaposed in a casing 10 with the bores 15 of adjacent plates misaligned so that a melt of synthetic linear polymer must pass through bores 15 and along capillaries 17, formed by the juxtaposed grooves 16, alternately in passing from a conduit 18 to a spinneret (not shown).  The diameters of the bores 15 and of the grooves 17 may decrease progressively from the conduit to the spinnerets.  As shown in Fig. 4, plates 20 are each provided with a central bore 22 and radial grooves 23 in the lower face only; they alternate with plates 21 of less diameter each provided with radial grooves 26 in the lower face only, the grooves communicating with a central depression of the same depth. Peripheral vanes (not shown) are provided on the edge of each plate 21 to centre it in the casing 25.  Flow is from a conduit 28 through bore 22 of the first plate 20, along grooves 23 in its lower face to an annular space 27, along grooves 26 in the lower face of the first plate 21, and into the central bore 22 of the second plate 20, and so on.  The cross-sections of the channels formed by the juxtaposition of grooves 23 or 26 with the ungrooved faces are of the same order as those in Fig. 1 and may similarly decrease towards the spinneret.  The material of the plates may be (stainless) nickel-chrome steel to resist corrosion by washing-agents such as nitric acid.  Perforate screens may be combined with or alternated with the plates or may be located p  before or after them.
