Title: Apparatus for gripping and drawing off yarn of the cop tip bunch for use in a cop-change automatic loom
IPC: D03D45/50
Filed: 1964-07-10
Abstract: 1,068,415. Bobbin changes. TOYODA AUTOMATIC LOOM WORKS, Ltd. July 10, 1964 [July 10, 1963; July 16, 1963], No. 28689/ 64. Heading D1E. A tip bunch is twisted to loosen it before being pulled off the cop. Before cop changing is initiated a cop C' is moved into the transfer position and the nipper 23 moves to the left as shown in Fig. 3 thus causes the nipper to strike the stop 39 which is rotatable only in an anticlockwise direction and a previous tip bunch, held by the nipper 23 is sucked away through the suction tube 38. The nipper moves on to the dotted line position and as is passes the stop 39' the jaws are again opened against the action of the spring holding them closed and the nipper grips the tip bunch. The nipper is then rotated in the appropriate direction to loosen the tip bunch and is taken back to the full line position of Fig. 3 the stops 39 and 39' being ineffective in this withdrawal. A loop of yarn is then pulled off into the suction tube 38 to provide a means of reducing excess tension in the cop changing operation. A brake is provided on the cop to prevent the loop of yarn from becoming too large. After cop changing the yarn is cut on the first pitch by a temple cutter and the end is sucked into the suction tube 38 where it is taken away when the nipper jaws are next opened.

Title: Sheet pin hole detector
IPC: G01N21/894
Filed: 1952-11-14
Abstract: 708,513. Photo-electric pin-hole detectors. UNITED STATES STEEL CORPORATION. Nov. 14, 1952 [Feb. 19, 1952], No. 28743/52. Class 40 (3) In a machine for separating metal sheets 18 with pin-holes from perfect sheets 14 in which a system of photo-cells 30 causes the operation of a deflector 10 in response to light received through a pin hole, the operation of the deflector in response to the light received by system 30 when a sheet leaves the light beam is prevented by a second photo-cell system 32 which responds to the light when the sheet leaves the beam but not to pin holes. With the aid of a further photo-cell 82 it is arranged that the operation of the deflector takes place when a holed sheet leaves the detecting system and not at the moment of detection of the hole. The amplifier 36 for the photo-cells 30 comprises D.C. amplifier 38, differentiator 44, 46, amplifier 40 with zero bias amplifier 42 biased to cut-off and a further differentiator 54, 56, and the voltage wave at points A . . . F in response to the leading and trailing edges of a sheet and to pin holes is shown in Fig. 3. The cell system 32 acts on a normally conducting tube 66. As each sheet leaves the light beam, the tube becomes non-conducting and so renders tube 62 conducting. As a result, the pulse F', Fig. 3, is suppressed at the point H and only the pulse F<SP>11</SP> due to a pin hole is able to cause gas tube 60 to fire. The firing of 60 produces no immediate effect but when the trailing edge leaves the photo-cell 82 an impulse is produced in the plate circuit of tube 60 to cause it to be extinguished and the resulting negative pulse from the cathode circuit is passed on by tube 88 and pulse lengthener 92 to operate gas tube 94 and so actuate the deflector.

Title: Improved process for the manufacture of salt
IPC: C01D3/06
Filed: 1921-11-02
Abstract: 195,675. Gibbs, W. E. Nov. 2, 1921. Brine, evaporating; separate heater and evaporator apparatus; condenser systems.-In making salt from brine, saturated brine is heated by being passed as cooling-agent through the tubes of a surface condenser for condensing low-pressure steam in a power plant, and the heated brine is evaporated by exposure to the air, the salt crystals being removed and the residual liquid again used as cooling-agent in the condenser. Calcium bicarbonate and calcium sulphate, which normally occur in natural brine prevent corrosion of the brass tubes, and additions of these substances are made if they are not present. The evaporation of the brine may be effected by passing it down cooling-towers containing wooden laths on which the salt is deposited, or by spraying it over cooling-ponds or bv running it over smooth solid surfaces such as enamelled metal surfaces, or steel surfaces coated with pitch or bituminous varnish. Specification 29698/09 is referred to.

Title: Improvements in and relating to electric control systems for apparatus operating on a strip of material
IPC: B65H23/198
Filed: 1934-10-11
Abstract: 445,479. Automatic control of strip tension. BRITISH THOMSON - HOUSTON CO., Ltd., Ltd., Crown House, Aldwych, London. Oct. 11, 1934, No. 29144. Convention date, Oct. 11, 1933. [Class 38 (iv)] Strip material 10 is unwound from a reel 11 by a motor 13 which may be driven at various speeds, as for example by the Ward Leonard control shown. Constant tension is maintained on the strip by a dynamic braking generator 260 the current output of which is maintained constant, for example, by the vibratory regulator 33. In order that the tension may remain the same for all speeds of the strip the output of the braking g generator 260 is adjusted in correspondence with speed adjustments of the driving motor 13. The resistance absorbing the output may be a rheostat 31 coupled directly to the hand wheel 44 which adjusts the field strengths of the Ward Leonard machines. In a modification using magnetic contactors for bring- ing the driving motor up to a basic speed magnetic contactors vary the braking resistance and subsequent control is obtained by a speed controlling rheostat coupled with a braking rheostat.

Title: Improvements in and relating to automatic voltage regulators
IPC: H02P9/14
Filed: 1935-10-22
Abstract: 466,208. Automatic control systems. PARSONS & CO., Ltd., C. A., TOPHAM, H. B., and EASTON, V. Oct. 22, 1935, No. 29157. [Class 38 (iv)] Electromotive force.-The voltage of an alternator 1 is maintained constant by varying resistance 3 in its exciter field circuit in response to the operation of two critical voltage circuits 4, 5, comprising resistance, capacity and self-saturable inductance having critical voltage values respectively above and below the desired voltage and energized from the alternator. The critical voltage circuits each supply a contactor 8 or 9 through a rectifier, the contactors being effective to short-circuit parts 3a and 3b of the resistance 3. At normal voltage, circuit 4 is operative and contactor 8 is held open. With fall in voltage, relay 8 is deenergized and the whole of resistance 3 is thus short-circuited. With a rise in voltage above normal, contactor 9 is energized and inserts the resistance 3b so that all of the resistance 3 is in circuit. In a modification, designed to prevent hunting, the contactors 8 and 9 are energized from a separate circuit 24 under the control of contactors 18, 7 supplied through rectifiers from the critical voltage circuits 4, 5 in which the resistances 14, 13 have a positive voltage resistance characteristic. By the use of such resistances the circuits 4, 5 impulse continuously for small voltage variations but pass steady current for large variations and thereby prevent hunting. In parallel with contactors 8, 9 are the field windings of a reversible motor 10 which reduces the portion 11 or 12 of the resistance 3 inserted or shortcircuited, while the contactor 8 or 9 is energized. An interlock contactor 6 under the control of contactor 18 is provided to prevent simultaneous energization of both windings of the motor 10, and controls the circuit contactor 8. Contactor 9 is only energized when both contactors 18 and 7 are closed by a rise in voltage above the required value. Contactor 8 is energized only when contactor 18, which is normally closed, opens due to a fall in voltage and de-energizes contactor 6 so as to close its contacts. The value of the desired voltage may be varied by control on tappings on the saturable inductances 15, 16 or on the supply transformer 21. Sensitivity control is effected by a potentiometer 17. Load and power factor compounding may be effected by injecting in series with the supply from the transformer 21 current components from transformers 19, 20 across a resistance 22. When machines, having regulators compounded as above, are operated in parallel, load sharing is obtained. Specification 414,647 is referred to.

Abstract: 1357498 Tempering glass sheets PPG INDUSTRIES Inc 22 June 1972 [23 June 1971] 29205/72 Heading C1M Shaped treated glass sheets G are tempered by employing a cooling station which includes a pair of opposed plenum chambers 76, 78 each having an array of nozzles 70, 71 through which a tempering medium such as air is delivered, and a pair of opposed contoured glass guiding elements 120, 130 spaced inwardly from the nozzles 70, 71 each element 120, 130 conforming to the shape desired for at least a part of the marginal portion of the sheet. Each glass grinding element preferably comprises a ring like member having the desired configuration and having a serrated edge covered with a fine wire mesh facing the glass sheet. Alternatively each element may be in the form of a discontinuous ring. Each plenum chamber and associated guiding element may be moved towards and away from the other chamber and element by means of an associated piston and cylinder device 98, 100. The chambers may also be moved vertically by means of cams 94, driven by a shaft 92. In use, a glass sheet G suspended vertically by tongs 22 mounted on a conveyer system 11, 20 is heated to 1220-1230 F. in a furnace 14 and then bent by a pair of moulds 32, 33. The sheet is then conveyed to the cooling station 18, where the plenum chambers are brought together so that the guiding elements are separated from each other by a distance only slightly greater than the thickness of the sheet G. Air is directed from the nozzles on to the sheet with a slightly greater pressure on the convex side of the sheet, thus driving the sheet towards the opposed guiding element which it touches momentarily and causing an increase in pressure on the concave side of the sheet. As a result the sheet oscillates between the two guiding elements. Such oscillation is stated to restore to the desired shape glass that has warped while the glass is being tempered.
