Patent GB-646166-A (GB)
Title: Improvements in or relating to injection moulding machines
IPC: B29C48/475
Filed: 1947-10-20
Abstract: 646,166. Injection - moulding machines. LESTER ENGINEERING CO. Oct. 20, 1947, No. 28061. Convention date, Nov. 19, 1943. [Class 87 (ii)] Plastic material is moulded into elongated forms by injecting the material under pressure into one end of an elongated mould cavity, applying a counter pressure at the other end of the cavity to exert a compression on the material during injection, solidifying the material in the cavity and positively gripping the end of the solidified material, then, upon completion of the injection, pulling on the solidified material remaining in the die cavity to extract it from the cavity. The material, e.g. a thermosetting resin, is injected by means of a plunger 3, Fig. 5, through sprue channels 33 into the annular cavity 32 which is closed at the left-hand end by a cylindrical extractor 11. During injection the extractor with its cross-head 14 is urged by the material to the left against the counter pressure of a hydraulic cylinder (not shown) acting through rod 12. The core 29 of mould 27 has a heating coil 34 so that the thermosetting material is solidified as it enters the cavity. The extractor 11 has, near its left-hand edge, a screw-threaded portion 43, Fig. 7, around which the plastic material moulds itself and sets. When the cavity is full and the plunger 3 at the end of its stroke, the pressure in the hydraulic cylinder is reversed to move the extractor 11 further to the left and pull the solidified tube with its sprues completely out of the cavity 32. The tube is then unscrewed from the plunger. In an alternative form of extractor mechanism, Figs. 8 and 9, the cross-head 14 has lower and upper pivoted jaws 55, 56 and is held against movement by hydraulic cylinders 52 during injection. A contractible bushing 62 having a diagonal split 63 is clamped between the jaws 55, 56 and in turn engages the extractor 11, the pressure being adjusted, by means of a nut 60, to provide a desired frictional resistance to the left-hand movement of the extractor as the material is injected by the plunger 3. When the injection is completed and the extractor has been forced through the bushing 62, the pressure in the cylinders 52 is reversed to move the cross-head 14 to the left and to pull out the solidified tube. Instead of hydraulic cylinders, a rack-and-pinion may be used for moving the cross-head 14. In order that injection cylinder 2 may be charged (e.g. with briquettes of the material) from the left-hand side, block 7 carrying the mould 27 is vertically displaceable in slides 39 to clear the orifice of the cylinder.

Abstract: 1,146,595. Seaming non-metallic sheet material. BAKELITE XYLONITE Ltd. 1 July, 1966 [5 July, 1965], No. 28465/65. Heading B5K. An ornamental device 1 is secured between a weldable thermoplastic material and a weldable substrate 6 by placing the device 1 between the material 2 and the substrate 6 and welding at 3, 4, by high frequency electrical means, the material 2 to the substrate 6 around the device 1 to form an assembly wherein the device 1 is secured between the material 2 and the substrate 6 and is visible when the assembly is viewed from the side of the material 2. Preferably, the substrate 6 is also a weldable thermoplastic material or it may be paper or cardboard coated with a weldable thermoplastic material. As shown, an ornamental stone 1 is held in position in an opening 5 in the material 2 by an annular flange formed between the inner weld edge 3 and the opening 5. The material 2 may be transparent or opaque. If a rigid transparent thermoplastic material is used it may be provided with a protruding vacuum-moulded section conforming to the shape of the device. If a stretchable transparent material, e.g. plasticized polyvinyl chloride, is used, the material is stretched over the device prior to or during welding. An outer framing layer of opaque thermoplastic material, e.g. a textile in the form of a satin impregnated with polyvinyl chloride, may additionally be provided. All three layers are welded together to secure the device. The assembly may comprise a decorative substrate co-extensive with a transparent thermoplastic material used for backing a circular hand mirror. Alternatively, the material 2 may be an opaque decorative material, e.g. stretchable imitation leather made of polyvinyl chloride, and the substrate 6 need not be coextensive with the material 2 but may be slightly larger than the device 1. The latter method may be used to secure an imitation gemstone to a manicure wallet.

Title: Improvements in television receiving apparatus
IPC: H04N3/34
Filed: 1936-10-20
Abstract: 483,385. Television. TRAUB, E. Oct. 20, 1936, No. 28507. Drawings to Specification. [Class 40 (iii)] A television receiver incorporates a light cell in which a medium is traversed by modulated mechanical waves, and a moving and a stationary scanning device are employed in such a way as to project one or more lines or the complete picture simultaneously. The light cell is preferably large enough to include all the elements of a complete picture which elements are moving through the cell in a direction away from the piezo-electric crystal. The image of these moving elements is rendered stationary by a rotating mirror drum and the various lines of the picture are selected by an echelon scanning device and projected into their correct positions on the screen. As the second picture begins to pass through the apparatus the next portion of the mirror drum projects its commencing lines into their correct positions as the corresponding lines of the previous picture disappear. The whole picture is therefore projected simultaneously and changes element by element. Specification 439,236 is referred to.

Title: Improvements relating to magnetic workholders
IPC: B23Q3/154
Filed: 1957-09-10
Abstract: 847,394. Permanent magnets. PANTON, J. R., and WEBB, A., [trading as PANTON & WEBB]. Sept. 10, 1958 [Sept. 10, 1957], No. 28586/57. Class 35. [Also in Group XXIII] A magnetic work-holder comprises a work-holding surface made up compositely of a plurality of spaced pole pieces 1a, 1b, alternate pieces 1a making one series and the remaining pieces 1b another series, and switch means to rotate at least one permanent magnet from positions wherein the work-holding surface is rendered operative and inoperative respectively. The pole pieces are in the form of rectangular rhombic, trapezoidal, triangular, circular or polygonal laminations of magnetic material separated by laminations 2 of non-magnetic material; the thickness of the laminations may or may not be the same. The laminations are provided with a circular hole 4 of the same diameter as the magnet 12 which is cylindrical with flat, chordal surfaces 15, 16 and poles N, S located adjacent the arcuate surfaces 13, 14 thereof. The holes 4 in the laminations 1a are enlarged to the right, as shown at 6, and those in the laminations 1b enlarged to the left, as shown at 8. With the magnet in the bores with the chordal surfaces vertical, each arcuate surface of the magnet transmits flux to the laminations 1a and 1b, the flux path thus being internal of the laminations and the work-holding surface inoperative. When the magnet is rotated, say clockwise, 90 degrees, the N pole of the magnet is only in contact with, and therefore transmits flux to, the laminations 1b and the S pole of the magnet is only in contact with, and therefore transmits flux to, the lamination 1a and the work-holding surface is operative, the flux path being completed by a workpiece held on the surface. The longitudinal sides of the workholder are also operative and the lower surface may be made operative by removal of a non- magnetic base 3. More than one bore may be provided in the laminations for a plurality of magnets and two magnets each provided with a rectangular extension 30 at one end disposed in each bore with the projections abutting each other and engaging a slot in a disc 33 which has diametrically opposed keyways 34 co-operating with projections 35 on a pinion 36. A handle 37 which is on a spindle having a pinion 38 engaging racks 43 is movable through 180 degrees to displace the racks which are connected to further racks 42 engaging the pinion 36 to rotate the magnets through 90 degrees; the racks are provided with adjustable stops. The magnets in each bore may be operated independently from those in the other bores. The surface of the work-holder may be flat, V-shaped or have a concave depression.

Patent GB-469463-A (GB)
Title: Improvements in the treatment of textile materials
IPC: D06M11/05
Filed: 1935-10-17
Abstract: Yarns containing both artificial and natural fibres are subjected to a treatment with steam before being woven or otherwise associated together to form a fabric.  Preferably, the steam treatment is carried out just prior to the weaving, knitting, warp knitting or other fabric forming operation so that this operation is effected while the yarn is in a warm moist condition.  The artificial fibres may be of regenerated cellulose, cellulose acetate or other cellulose ester, ethyl cellulose or other cellulose ether.  Filaments of organic cellulose derivatives may be obtained by dry or wet spinning methods and they may contain dyes, lakes, de-electrifiers, pigments, lubricants, fillers plasticizers, and sizes.  The filaments may be cut or broken to staple length and mixed or doubled with fibres or yarns containing wool, cotton, flax, or silk.  The mixed yarns may be formed into cones, bobbins, cheeses, or spools, and these are placed in a chamber filled with steam.  The steam may be wet or dry and at atmospheric or raised pressure.  If desired, the steam may be forced or sucked through the yarn packages.  Steam treatment may be carried out just after twisting the yarn and again just before forming the yarn into fabric.  In an example, yarn containing cellulose acetate and wool is spooled and subjected to wet steam.  It is then warped. A similar yarn is steamed for a shorter time and woven into the warp as a weft.  The steam treatment renders the wool and the whole yarn more pliable, tends to set the twist, and facilitates weaving.

Convention date, Oct. 14, 1931. [Class 97 (ii).] An aircraft is provided with two bodies each containing two symmetrically disposed nozzles, one pair being in a vertical plane and directed upwards and downwards and the other pair being in a horizontal plane, these nozzles through differential manometers automatically controlling the elevator and ailerons or adjusting an indicator on the dashboard. Two streamlined bodies having symmetrically disposed nozzle openings d<1>, d<11> are arranged on the wings, one with its plane ofsymmetry parallel to a horizontal plane and the other with its plane parallel to a vertical longitudinal plane. The nozzle throats are connected to capsules m<1>, m<2> which normally hold a pointer z in mid position between contact strips c, Fig. 3, carried by a spindle b which is constrained by a spring f, levers g, and a crank n to assume a normal position. Any movement of the pointer z energizes magnets e<1>, e<2> to move the spindle b in a direction to follow up the pointer, this motion being damped by a fluid friction device p, this friction device also resisting the return motion produced by the spring f. Simultaneously, rotary magnets control air-valves of cylinders acting upon the elevator or aileron controls. As applied to an indicating instrument, the pointers z act through devices similar to that shown in Fig. 3 upon rotary magnets T', T', Fig. 5. The magnet T' rotates a semicircular disc S, the top edge of which represents the horizon, by means of links r<1>, r<2>, r<3> in front of a disc representing the sky. The magnet T<1> raises and lowers the disc S by means of a lever u<3> link u<2> and angle lever u<1> centred on the axis of the magnet T2. In front of the disc S is a transparent disc having an outline of the bonnet g of the machine. The disc S may bear a photographic representation of the ground. A pointer may be moved transversely across the instrument in response to a turn indicator.
