Abstract: 1,141,934. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORP. 9 March, 1967 [14 March, 1966], No. 11046/67. Heading B6B. The top sheet of a stack 31, Figs. 1 and 2, is separated by a suction device comprising a plurality of mouths 3 and feet 4 mounted on an arm 15 of a linkage comprising arms 14, 15, 16 so as to move in a cycloidal path through positions 1a, 1b 1c, 1d. In the position 1c the sheet is delivered to a suction band 35 and the suction of the suction device is released by a valve 8 controlled by an end 27 of the arm 14, which is pivoted at 18, the arm 16 being pivoted at 20. The suction device then retracts its path to 1a under control of a cam 24. A second suction device 45 with a lesser degree of suction is mounted on a second linkage 49, 50, 51 and moves from position 45a to 45b to engage a second sheet 60 which may have been separated to hold it until the first suction device returns to 1b

In one form, shown in Fig. 1, a lapping of strip material B is applied to the conductor A so as to form a loose sheath and to provide a support for the paper or other insulation C. The tape may be of metal, preferably non- magnetic or of a non-metallic material, the inner surface of which is metallized to prevent gaseous ionization. The edges of the strips may interlock in the manner of flexible gas or steam tubing. Fig. 2 shows a modification in which the strip B<1> is formed with small projections B<2> or ribs which contact with the conductor A<1>. The supporting sheathing may be formed as a helix of wire. B<3>, Fig. 3. When the construction is such as to form an uneven exterior surface, a covering of foil, as shown at D, Fig. 3. may be provided before the insulation as applied. The invention is also described as applied to concentric cables or multicone cables. The space surrounding the conductor is filled with the oil or compound used for impregnating the insulation.

Abstract: 1,135,765. Linear motors. PLESSEY-UK Ltd. 17 March, 1966 [17 March, 1965], No. 11327/65. Heading H2A. The two members of the motor are arranged one within the other with an intervening tubular air gap. The facing peripheries of the members each have teeth at intervals lengthwise of the air gap. One member has windings so inter-related that when appropriately energized they produce a lengthwise moving magnetic field and the other member includes a permanent magnet affording different polarities of opposite parts of this other member transversely of the air gap. Preferably the members are cylindrical and arranged coaxially, as shown. Preferably the first-mentioned member is the outer one and is the stator. Preferably the pitch of the teeth on the first member differs from the pitch of the teeth on the second member, (the actuator), and the pitches bear a prime ratio to each other. Alternatively, the respective tooth pitches are the same, but the teeth on one of the members are arranged in groups which are spaced apart by a distance different from the tooth pitch. The teeth extend circumferentially on the stator, but the actuator incorporates two hemicylindrical polepieces, each polepiece having circumferential teeth axially displaced relative to the teeth on the other polepiece; these polepieces surround a cylindrical permanent magnet magnetized diametrically. Using D.C. excitation and appropriate switches the motor operates as a stepping device; using A.C., uninterrupted linear displacement is obtained.

Title: Improvements in or relating to material testing machines
IPC: G01N3/00
Filed: 1947-04-30
Abstract: 634,215. Testing physical qualities of material WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 30, 1947, No. 11531. Convention date, May 27, 1944. [Class 106 (ii)] [Also in Group XXXVIII] The deformation of a test specimen 34 (Figs. 1 and 3) under load is measured by the relative movement of two parallel comparison rods 55, 57 connecting spaced points of the specimen to comparison plates 59, 60 respectively, the plates being connected by flat springs 85, 86 which allow only relative axial movement of the rods during testing. In the machine shown in Fig. 1, the specimen 34 is screwed into upper and lower grips 35, 36 which are screwed into a loading bar 29 and anchor bar 37 respectively. The bar 29 is supported by a knife-edge 27 on one end of a pivoted lever 21 having weights suspended from its other end. The bar 37 passes between cross-channel irons 14 of the supporting framework into a seat 38, and is prevented from falling when the specimen breaks by a collar 40a. The specimen may be heated in a cylindrical electric furnace 41 slidably mounted on a square rod 45. Strain-measuring ; extensometers. Upper and lower pairs of rods 55, 57 (Fig. 3) are connected to the specimen 34 by plates 67, 72 fixed by pins 69, 74. The lower comparison plate 60 is connected by a stiff wire 83 to the grip 36 to prevent swinging. An electric contact on the plate 59 normally engages a contact on a micrometer 62 on plate 60. Relative movement of the plates due to extension of the specimen, breaks the contacts which are reengaged by an electric follow-up device (see Group XXXVIII) including a motor 50 which moves up the micrometer through reduction gears, the number of revolutions of the motor being registered on a counter 52. A normally open shut-off switch (not shown) is closed by the weighted end of the lever 21 (Fig. 1) if the specimen breaks, so as to prevent any further operation of the motor. In a modification (Fig. 11), the relative movement between plates 59, 60 is magnified by a frictionless leverage device. The plate 59 carries a block 136 which extends through a hob in a plate 125 mounted on and spaced from the plate 60 (not shown). A block 132 fixed to the plate 125 is connected to the block 136 by a leaf-spring 138 bolted at its centre to a leverage block 133 fixed to a magnifying arm 124 providing the upper electric contact at its other end. The blocks 132, 136 are also connected to the block 133 by pairs of leaf-springs 131, 135. A handoperated micrometer may be substituted for the motor 50 and counter 52; and a signal device, e.g. a lamp, may indicate when the contacts are separated. A modified means for securing the comparison rods to the specimen, comprises a pair of blocks 116, 117 (Fig. 10), bolted around the specimen, from which the plate 67 or 72 (Fig. 3) is suspended by rods 114, 115. U.S.A. Specification 2,077,598 is referred to. '

Abstract: 400,602. Door-operating mechanism. POWER, R. F., 18, Chesterford Gardens, Hampstead, London. April 25, 1932, No. 11898. [Class 65 (i).] Two centrally-pivoted revolving doors 1, 2, Fig. 1, are arranged in the casing 5, 6, 7 of a passageway, and are geared together so that they rotate in unison, their axes being so set that when one closes the passage the other is longitudinally disposed thereof. In the form shown, the lower pivots 3, 4 carry pinions 9, 10, which mesh with pinions 11, 12 on a split shaft 13. A clutch 14 comprising a spring-actuated striker 15 normally locks the two parts of the shaft together. To enable the two doors to be rotated independently, the clutch parts are separated by a pivoted rocker 20, one end of which engages with the striker 15, the other end being connected to a manuallyoperated pivoted lever 18. In a modification, the pivots carry sprocket wheels 24, 25, Fig. 4, interconnected by an endless chain 26 which passes around two further sprocket wheels 27, 28. The wheel 27 is mounted on a slide 30 operated by a screw-threaded rod 31, and the wheel 28 is carried by a spring-controlled pivoted lever 28a. Both doors may be arranged in alignment centrally of the passage by locking one door, for instance the door 2, in that position and then operating the rod 31 to move the wheel 27 transversely across the door opening. The tension of the chain, during this operation, is maintained by the lever 28a, and the consequential movement of the chain effects the rotation of the sprocket wheel 24 of the door 1. The operating mechanisms above described may be arranged either above or below the door frame. In other modifications, the pivots 3, 4 carry two frames each holding either one or two swing doors.
