Title: A pattern control attachment for tufting machines
IPC: G05B19/12
Filed: 1961-08-25
Abstract: 919,446. Sewing-machines. SINGER-COBBLE Inc. Aug. 25, 1961 [May 29, 1961], No. ,30646/61. Class 112. [Also in Group XL (b)] A tufting machine has means for varying the length and/or kind of the pile produced, the means comprising a photo-cell, a light source adjacent the photo-cell, a pattern member having light-transmitting areas and opaque areas and means for moving the pattern member between the photo-cell and the light source. In one embodiment the tufting- machine is of .the type described in Specification 780,370, wherein yarn is fed to the needles by a pair, 10, of oppositely-rotating feed rolls 12, 13, which may be selectively connected by magnetic clutches 25, 27 to a high-speed drivesprocket 24 or to a low-speed drive-sprocket 26 to produce long or short tufts according to the required pattern. As shown, the pairs of feed rolls 10 are mounted in two horizontal rows, each row and its sprockets 24, 26, being driven from the opposite end of the machine, preferably at different speeds, so .that four different pile lengths may be provided in the pattern. The mechanism controlling the clutches comprises a pattern drum 45 comprising end-plates 46 and an intermediate cylinder 47 of translucent glass or synthetic plastic. Elongated light bulbs 55 are disposed within the cylinder and a unit 58 above the drum contains a plurality of photocells, one cell for each pair of rolls 10. The drum is driven by belts 51, 53 from the fabric feed rolls 6. Each cell is connected electrically through a transistor amplifier to the appropriate clutches 25, 27. It is stated that the control mechanism may be used to control the selection of needles in the machine described in Specification 910,604 or in the machine described in Specification 853,527. Controlling motors.-The two driving motors, one of which is shown at 3, are mounted at opposite ends of the machine and are connected to a common power supply. Their starting circuits include a relay operated by the power supply to the yarn feed clutches and a relay operated by a lamp monitoring photo-cell so that either failure of the clutch supply, which would render both clutches inoperative and stop the yarn feed, or failure of the lamps 55, which would maintain the high-speed clutches 25 engaged continuously, will stop the machine. Lights in the circuits burn to show functioning of the clutch supply and the lamp. A time delay is incorporated in the circuit of the lamps 55 to keep them in operation when the machine is shut down for a limited time for adjustment, but shuts off the lamp if the machine is stopped for an extended period, to prevent the heat from warping the pattern sheet 57. Specification 735,019 also is referred to.

Abstract: 1,001,931. Mounting helicopter rotors. BELL AEROSPACE CORPORATION. Aug. 4, 1964 [Aug. 27, 1963], No. 30831/64. Heading B7W. A rotary wing aircraft has a pylon mounted on a fuselage and comprising a rotor and means for transmitting power from an engine to the rotor. The pylon is mounted on the fuselage by supports on each side pivotally attached to the fuselage and the pylon and so arranged as to restrict lateral movement of the pylon to rotation about a generally longitudinal axis. As shown, the pylon 1 is supported by arms 6 pivoted at 5 and 8 to the pylon and fuselage, respectively, the pivots 5 and 8 on each side lying on planes which intersect along an axis a-a which preferably passes through the centre of gravity of the fuselage, and is preferably normal to the resultant torque vector on the pylon in normal flight. The inclination of the axis a-a is caused by the front pivots 8 being more widely spaced than the rear pivots 8. The pivots 5, 8 may be cylindrical bearings as shown, or spherical, and the pylon can therefore pivot only about the axes a-a and b-b. A rubber vibration isolation mount 12 provides partial restraint against rotation about these axes. The arms 6 are preferably attached to the fuselage close to main structural members to provide high vertical stiffness.

Abstract: 611,415. Piezo-electric crystals. BRUSH DEVELOPMENT CO. Nov. 16, 1945, No. 30887. Convention date, Nov. 18, 1944. [Class 40 (v)] A piezo-electric plate or slab is cut as claimed in Specification 592,222, i.e. its longest dimension is piezo-electrically active, and, of the two other dimensions, the longer is inactive and the smaller is active. This reduces friction between the end of the plate and a base: According to the invention, the plate is cut from a crystal in one of the classes D4, D6, T, Td or Vd in the Schonflies system of classification. The invention is illustrated by class Vd which includes the primary phosphates and arsenates of ammonium, potassium, rubidium and all substances isomorphous with them. A Vd type crystal consists of a rectangular bar 160 with pyramidal ends 162. An electric field applied along the longitudinal Z-axis produces piezoelectric action in directions at 45 degrees to the major side faces. Thus, in a bar 166, Fig. 3, cut with its faces at 45 degrees to the side faces of the mother crystal expands and contracts along its major faces when a voltage is applied between the ends. Thus, plates 167, 168, 169 fulfil the invention, since the longest and shortest dimensions are piezo-electrically active and the width dimension is inactive. Fig. 4 shows plates 167, 168 mounted together with a field applied from edge electrodes 170, 171 so that one plate expands when the other contracts, thus forming a bender unit.
