Title: Tufting machines for producing terry-like fabrics
IPC: D05C15/22
Filed: 1966-11-11
Abstract: 1,098,219. Tufting machines, tufted fabrics. SINGER CO. Nov. 11, 1966 [Nov. 15, 1965], No. 50551/66. Headings DIG and D1K. Pile fabric is formed by projecting a yarncarrying needle through a backing fabric to form a first loop, holding the first loop while the needle is withdrawn, advancing the backing fabric, projecting the needle through the backing fabric and through the first loop to form a second loop, releasing the first loop so that it collapses and surrounds the second loop, holding the second loop while the needle is withdrawn, and releasing the second loop so that it projects loosely from the backing fabric and is engaged by the first loop. A main shaft 10, journalled in side plates (2), 3 secured to side members 8 of a stand 6, reciprocates a needle bar 38 carrying needles 39 which pass between fingers 21, 91 projecting from lower and upper plates 20 and 90 respectively. The backing fabric F is supported by plate 20 and is fed in the direction A by rolls 22, 23. Yarn Y is supplied to the needles by feed rolls 44 via an oscillating take-up bar 57. An oscillating shaft 82 carries first loopers 80 which move towards the needles against the direction of work feed. Second loopers 74 are reciprocated from a rotary shaft 66 and move towards the needles in the direction of work feed. Shafts 66 and 82 turn at half the speed of shaft 10. The arrangement is such that on a first penetration of a needle at a point S1, the loop L1 thrown by the subsequently rising needle-is held by a looper 80 until the needle passes through loop L1 at a second penetration at a point S2. Looper 74 then holds the loop L2 formed by the ascending needle. When the needles are fully raised, plate 90 is moved laterally by a distance equal to the needle spacing, whereby the descending needle lays an upper loop L3 over a finger 91. The cycle is then repeated.

Title: High frequency electron discharge devices of travelling wave type and slow wave circuits
IPC: H01J23/24
Filed: 1965-12-06
Abstract: 1,090,040. Travelling-wave tubes. VARIAN ASSOCIATES. Dec. 6, 1965 [Dec. 11, 1964], No. 51684/65. Heading H1D. A helical or helix-derived slow-wave structure 62 is supported by longitudinal fins 63, 64 within a waveguide 65, the fins being provided with slots e.g. slots 67, 68, 69, which have the effect of perturbing certain unwanted modes of propagation. Up to eight such fins may be used (two are shown). In such structures, the slow-wave circuit comprises two (or a number of pairs of) more or less independent parts each of which propagates a wave, the two waves being coupled by the helix. The structure will, therefore, support two independent transmission modes, viz.: the " in-phase " mode in which the axial electric fields on either side of the diameter defined by the fins have the same direction at any instant, and the " out-ofphase " mode in which the fields have opposite directions. The pass bands of lowest order for the two modes are almost identical and the purpose of the slots is to shift the upper, or lower, or both cut-off frequencies of the in-phase mode, whereby stable operation in the out-ofphase fundamental mode may be obtained. The effect of the slots is to lengthen the paths of axial and radial currents associated with the in-phase mode, slots of one of the types shown being distributed along the whole delay line. The mode of operation and the effect of the slots is discussed in detail with reference to Figs. 10-17 (not shown). The slots may have oblique edges to avoid impedance discontinuities. The embodiment described is a backward-wave oscillator in which the waveguide 65 is provided with a pair of loading ridges extending from opposite points on the interior of the waveguide in a diametral plane at rightangles to the plane defined by the ridges. A modification using a single fin is described.

Abstract: 1487085 Vibrators HUNTER AUTOMATED MACHINERY CORP 29 Nov 1974 [21 March 1974] 51710/74 Heading F2X A vibrator operable by pressure fluid comprises a body 11 with its ends constrained between elements A of an article to be vibrated, e.g. a foundry flask FF, and has a bore 12 in which a spool 13 is slidable. A plug P formed of impact resistant material is disposed in each end of the bore 12 and transmits impulses upon reciprocation of the spool 13. The spool 13 has alternating grooves and lands, viz. a central groove 14 flanked at each side by a land 16, 17, which in turn are flanked by grooves 18, 21 and lands 19, 22 of lesser diameter than the bore 12. Pressure fluid is supplied by a manifold 24 connected with pressure lines (not shown) and having a longitudinal bore intersected at right angles by a passageway 28 into which is press fitted a valve seat 31. A valve poppet 29 has a face 29A normally seated against the valve seat 31 and is biased by a spring 38 between it and the valve seat 31. Normally, the pressure fluid is supplied through ports 39 to an annular chamber 40 in the bore 12 adjacent groove 14. The body 11 is held by screws 11A tapped into a mounting plate MP provided with spaced milled slots forming passageways 41, 42 connected to bore 12 by ports 46, 46A and 43, 43A respectively. In the Fig. 1 position, the left-hand end of the bore 12 is connected to exhaust through a port 47 while at the right-hand end pressure fluid is applied to face 17B of land 17 by way of passageway 42 and ports 43, 43A and the spool 13 is moved to contact the left-hand plug P. An exhaust port 48 is now uncovered, reducing the pressure to the right of spool 13 while pressure fluid is applied to face 16B of land 16 by way of passageway 41 and ports 46, 46A and the spool 13 is moved back to contact the right-hand plug P. Reciprocation of the spool 13 thereby results. Upon stopping the vibrator, the spool 13 may by chance become centred covering both exhaust ports 47, 48. The poppet 29 will then be biased to a position closing ports 39 (as shown in Fig. 3) and the initial flow of pressure fluid will then be via passageways 33, 34 to face 17B of land 17 to effect movement of the spool 13. If the spool 13 is offset in either direction, passageways 33, 34 are not important and reciprocation will begin normally.

Abstract: 1,157,696. Making conductor coils. REYNOLDS METALS CO. 23 Nov., 1966 [7 March, 1966], No. 52491/66. Heading B3A. [Also in Divisions B6 and H1] Strip conductor coils are made by coating a strip of conductive material 72, e.g. aluminium, with insulating material, e.g. epoxy resin, whose longitudinal edges are adjacent those of the strip and removing the edges of the conductive material to form new edges inwardly offset from the edges of the coating before the strip is wound into the strip conductor coil. The conductor strip 72 is coated by rollers 77 on its underside and the resin partially cured in a heater 78. The strip is then slit longitudinally into strips 31 and wound on a pair of shafts 80. Each shaft containing a number of wound strips 43 is dipped in an etching bath containing caustic or acid wherein the conductive material is etched to offset its longitudinal edges from those of the coating. After etching for six minutes the wound strips 43 are rinsed and deoxidized for two minutes in dilute sulphuric acid. The wound strips are wound on a core (32), Fig. 1 (not shown), and the coating completely cured by heating which also heat seals the turns and blocks the coil ends. The heating may be in an oven, or by induced eddy currents or by passing current through the strip. The wound coil can be shaped prior to curing, Fig. 6 (not shown). In an alternative embodiment the strips 31 are passed through etching baths before being wound directly into a conductor coil.

Abstract: 1388317 Delaminating E I DU PONT DE NEMOURS P CO 21 Nov 1972 [23 Nov 1971] 53737/72 Heading B5N [Also in Division G2] The receptor sheet is delaminated from a discrete sensitized element D, comprising a substrate B (e.g. of copper-clad glass fibrereinforced board), having on at least one face a resist layer R and a receptor sheet S, by pressing a continuous web W on to the receptor sheet at an adhesion station and removing the web W with the sheet S adhered thereto. Prior to delamination, the resist layer R may be exposed imagewise to actinic radiation to harden areas thereof. In Fig. 3, the hardened areas H and part of the unhardened area U are removed with the sheet S to leave a substantial part of the area U on the substrate B as a negative image; alternatively the hardened areas may adhere more strongly to the substrate, thus producing a positive image by delamination of the sheet S and area U. The adhesion of web W and sheet S is preferably caused by an adhesive layer A attached to either W or S and by application of pressure, e.g. by nip rollers 18, 18<SP>1</SP> or by non- rotary rods or shoes. The adhesive may be heat- or pressure-senstiive. Such heat as is necessary is applied before adhesion (by platens 11, 11<SP>1</SP> or a heating chamber), and/or during adhesion via the pressure members. As shown in Fig. 2, the element D is slid between heated platens 11, 11<SP>1</SP> and then falls into the nip of rollers 18, 18<SP>1</SP> around which the web W passes from rolls 36, 36<SP>1</SP> to rolls 35, 35<SP>1</SP>, the gaps between the platens and nip rollers being controlled by pistons 32, 32<SP>1</SP>, 33.

[Also in Division G3] An escapement controlled balance wheel 1 comprises an oscillating balance wheel-coil spring assembly 1, 2 operatively engaging a lever 6 adapted to close, during its movement, a nozzle 8 connected to an air pressure source 10, and a bellows 12 connected by a rod 13 to an arm 14. During the clockwise movement of the balance wheel, an eccentrically mounted pin 5 on a roller 4 rotates the forked lever 6 until the lever engages a pin 19, a magnet 20 holding the lever against the pin. In this position the lever closes the nozzle 8 thereby causing an increase in the pressure in the bellows. The bellows expands and the rod 13 rotates the arm 14 until the arm abuts a stop 22. On the return movement of the balance wheel, the pin 5 rotates the lever 6 to open the nozzle 8, thus releasing the pressure in the bellows and a spring 15 returns the arm 14 to its initial position thus winding up the spring and restarting the cycle. In a modification, two opposed nozzles are mounted within an hermetically sealed chamber of a pneumatic switching device. One nozzle is connected to a pressure source whilst the other nozzle is open to the atmosphere, and a baffle, flexibly connected to the lever, is placed between the nozzles. The lever may comprise two parts, one part being enclosed in an hermetic chamber and magnetically operating the other part.
