Title: Method of, and apparatus for, preparing slivers
IPC: D01G1/10
Filed: 1937-11-06
Abstract: 505,198. Preparing slivers from a hank. BREMER WOLL-KAMMEREI AKT.-GES. Nov. 6, 1937, No. 30456. Convention date, Nov. 6, 1936. [Class 120 (iii)] In making a continuous band or sliver from a hank a, Fig. 1, of cellulose fibres by cutting the hank transversely to its thickness the fibres are drawn off individually or in groups as the cutting action proceeds so that each section cut is divided into a number of layers. The hank a is fed by rollers b, b<1> for a distance F beyond the anvil d. The feed rollers are then stopped and the blade e cuts the fibres of the hank end a<1>, take-up rollers g, gl which may be fluted, plain roughened or provided with needles rotating as the.blade e descends so that the cut fibres are fed forward in layers I, II, III ... to the delivery rollers h, h<1> and then formed into a sliver. When all the fibres in the part a<1>, have been delivered the rollers g, g<1> ; h, h<1> are stopped, the roller g is raised and another section fed forward by the rollers b, b<1>. Needle bars i, i<1>, Fig. 2, may be substituted for the rollers g, g<1>. In a modification, the rollers, g, g<1> or needle bars i, i<1> are stopped :before all the cut threads have been delivered from the table f and the end a<1> of the next section is deposited on the remaining fibres so as to form a continuous sliver, by feeding the end a<1> forward on an inclined support k, Fig. 3, which is then lowered on to the table f and withdrawn, or by use of a plate which, during the feed forward, supports the end a<1> above the residue on the table f and is then retracted.
Patent GB-306535-A (GB)
Abstract: 306,535. Electrical Research Products, Inc., (Assignees of Marrison, W. A., ,and Horton, J. W.). Feb. 24, 1928, [Convention date]. Television synchronous movements.-In a television system the scanning apparatus at the transmitter and receiver are maintained at the same speed by independent motors controlled by piezo-electric or like means, small phase variations being applied manually. Thus at the receiving station the scanning disc 8 is driven by a motor 9 but its speed is controlled by a synchronous motor 10 which is driven by alternating current supplied to the winding 10<1> at, say, 2983 cycles. This current is obtained by stepping down a frequency of 60 kilocycles derived from a crystal-controlled oscillator 0-25, the frequency of which can be precisely adjusted bv means of the variable condenser 35 shunted on the crystal 38. The output of this oscillator is applied to the controlled submultiple-frequency generator SMG-26, the frequency of which is thus maintained at “ of that of the primary oscillator. A further similar system SMG-27 divides the reduced frequency by 6, so that the frequency passed on by the amplifier A-16 is 2083. In order that the phase of the receiver may be adjusted to that of the transmitter, and that the picture may thus be framed, the motor 10 is temporarily connected, by operation of the switch 30 from the key 51. to the oscillator 0-50, which is adjusted by means of the variable condenser 50<1> to generate oscillations differing slightly in frequency from 2083 cycles'. The picture then drifts across the screen until it is correctly framed, when switch 30 is released and the crystal- .controlled oscillator 0-25 resumes control of the - motor 10. In order that these operations may be effected without shock, oscillations from the sources O-50 and SMG-27 are applied to the beatindicating circuit 55, the indications of the instrument 56 giving the required guidance. When the picture has been framed, any slight drift which may occur after the condenser 35 has been finally adjusted to set the speed is corrected by means of the keys 65, 63, which momentarily cut in or out the condensers 61, 60, so as to alter slightly the frequency of the generator 0-25. In an alternative arrangement (Fig. 2, not shown) the low-frequency generator 0-50 may be abolished and an oscillator, generating a frequency which differs to a slight and adjustable extent from that of the valve O-25, may be adapted to be momentarily substituted for that valve by the operation of the switch 30.

Abstract: 1,079,471. Mechanical storage devices. S. CAPPELLI, and R. FARUSI. Aug. 4, 1964 [July 22, 1963], No. 30767/64. Heading B8E. A storage device comprises a plurality of trolleys 10, Figs. 1 and 2, which are disposed in a row and are movable longitudinally of the row to provide a passage between any two adjacent trolleys. The trolleys may carry shelves and have wheels 12 which run on rails 13; the wheels 12 on at least one side of each trolley may be mounted in pairs having their axes disposed at an angle, the associated rail or rails having a cross-section of inverted V- shape. The trolleys are moved by two rods 19, 20 attached to internally-threaded members 16, 17 which are engaged with threaded spindles 21, 22 driven by a motor 18, the rods being moved in opposite directions and the trolleys having frictional means thereon for selectively engaging one or other of the rods depending upon the required direction of movement. The frictional means on each trolley comprises members 36, 37, Fig. 3, which are selectively moved into frictional engagement with the rods 19, 20 by rotation of eccentrics 33, 34, the latter being mounted on a rod 32 which is rotated by a hand lever 35. The motor 18 may be started by movement of the lever 35 to engage the members 36 or 37 with the rod 19 or 20. In a alternative construction, Fig. 4 (not shown), the rods 19, 20 are secured to members which run on guide rods and are moved by a rope. The members 16, 17 may be returned to their start position shown in Fig. 1, by them operating limit switches at the end of their travel, to reverse the motor 18. The frictional means of engaging the rods 19, 20 may be replaced by electromagnetic means the selective use of which may also determine the direction of rotation of the motor 18 thereby rendering unnecessary the return of the members 16, 17 to their start position. In further alternative construction the trolleys are moved by an hydraulic or pneumatic system.

Abstract: 1,194,837. Internal shoe drum brakes. GIRLING Ltd. 27 June, 1967 [9 July, 1966], No. 30936/66. Heading F2E. In an internal shoe drum brake having a back plate 10 and at least one shoe 28 pivoted at 44 to a carrier 42, the shoe 28 is arranged to engage an abutment so as to receive drag force from the shoe, an actuator 41 having an abutment 43a which engages one end of the carrier 42 and a further abutment 43a engaging the other end of the carrier 42. The last two abutments are arranged so that the carrier ends may move in a direction substantially at right angles to that of the force provided by the actuator 41. As described, the ends of the shoes 28 are interposed by double-acting hydraulic actuators 12, 14. Each shoe 28 is pivoted at 44 to a carrier 42 comprising one or more plates. The left-hand ends of the carriers 42 are supported at 43a by the ends of tappets 41a on a manual adjuster 40. The right-hand ends of carriers 42 are supported by the ends of tappets 41 on a hand-brake actuator 38. The ends of tappets 41 are slotted and contain wedges 48 which engage a surface on the shoe 28. This construction enables the shoe assemblies 28. 32 to slide to the right when the vehicle tends to roll back after braking. Alternatively, as in Fig. 4a, surfaces 43 of the carrier may engage rollers at the ends of tappets on the actuator and adjuster, the rollers being retained by springs 74 passing around shallow grooves 76 in the rollers. Alternatively, as in Fig. 4b, tappets 41 of the actuator may comprise a cylindrical member 88 having a return spring 96 contained in a recess 90. The tappets may be actuated by a wedge (Figs. 2 and 3, not shown).  Adjustment of shoe relative to carrier.-In Fig. 5 one web of the shoe is attached to a carrier 102 by means of a bolt 106 having a threaded shank portion 104 which extends eccentrically and carries a cylindrical boss 108 so that lateral movement of the shoe 100 relative to the carrier 102 may be achieved by rotation of the bolt 106.

[Class 23] [Also in Group XII] A dust-separator comprises a casing in which gas flows past dry vanes 5 so arranged that gas escaping between them has been deflected backwards and then flows immediately between wet vanes 6 set at such an angle to the dry vanes as to give the gas a zigzag passage. The vanes may be arranged as concentric circles in a centrifugal separator 1 with a tangential gas inlet 3 with a movable flap 4, the gas finally passing to an upper outlet 7. The separator 1 may communicate with a secondary centrifugal separator 2 also containing wet vanes. Water and dust are collected below. The upper ends of the wet vanes may be curved and be wetted from above by pipes 14 on both sides or only on the side on which gas impinges and sprays 16 may be used. The wet vanes may be used in adjacent sets, and water from one set may be fed to the next in the direction of gas flow or in the opposite direction as shown in Fig. 5a. The rear edges of the vanes may be bent to minimize entrainment of water by the gas.
