Title: New or improved work-handling means for power-presses and like machines
IPC: B21D43/10
Filed: 1953-05-11
Abstract: 743,544. Work handling means for presses. EVANS, F. A. May 11, 1954 [May 11, 1953], No. 13028/53. Class 83 (4). A work handling device for a power press or like machine comprises rigid substantially vertical arm 12 pivoted to swing about a fixed pivot 15 at its upper end and having pivoted to its lower end a work-gripping mechanism 65, 66 and a motor 33, preferably operated by pressure fluid, which when energized first moves the gripping mechanism about its pivot 46 to lift the workpiece clear of the tools or the like, and then swings the arm about its pivot 15 to carry the workpiece clear of the press to a point of discharge. The gripping mechanism comprises a pair of adjustable pins 65 mounted on a bar 62 and a spring-loaded jaw 66 pivoted at 68 to the bar which is secured to a sleeve 63 slidable along a spindle 61 carried by a block 60 adjustably secured by bolts 56 to a bracket 45 pivoted at 46 to a telescopically adjustable extension 40 of the swinging arm 12. A fluid-pressure motor 72 rigid with the block 60 acts through a strong spring 75 to slide the bar 62 and the pins and jaw 65, 66 along the spindle 61 towards the workpiece whereby the pins pass over the workpiece and the jaw under it. When the sleeve 63 engages an abutment 64, further movement of the motor 72 causes the spring 75 to be compressed, whereby a cam 70 on the motor rod moves the jaw 66 about its pivot to grip the workpiece. A main fluid-pressure motor 33 is then energized whereby its rod 32 moves a pair of quadrant plates 28 about their pivot 25 on a main mounting bracket 10. These quadrants are connected by a rod 30 and an adjustable screwed rod 49 to the bracket 45 so that the latter and hence the gripper jaws are moved about their pivot 46 to raise the workpiece. An abutment 37, Fig. 2 (not shown), on the quadrant plates subsequently engages a block 38 adjustably secured to a pair of arms 24 pivoted to the pivot 25 and to a collar 18 adjustably mounted on the arm 12. The upper end of the latter is secured within a fitting 13 carried by bell-crank levers 14 pivoted at 15 to the main bracket 10. Continued movement of the motor 33 thus causes movement of the arms 24 about the pivot 25 whereby the arm 12 and bell-crank levers 14 move about the pivot 15 to swing the workpiece clear of the press. The motor 72 is then reversed to release the workpiece and the motor 33 is reversed to bring the arm back to its starting position. The device is detachably mounted on the frame of the press and is preferably operated automatically in timed sequence therewith. The starting movement of the device is initiated by a switch operated by a cam on the crankshaft of the press when the latter begins its return stroke and switch means are provided for preventing the clutch of the press being engaged if the gripping mechanism is in the way of the press tools. Instead of gripping jaws, the gripping mechanism may comprise a suction device or an electro-magnetic device. Two work-handling devices operating in synchronism may be fitted to the press.
Patent GB-763501-A (GB)
Title: Improvements in or relating to a method for insolubilising artificial filaments, threads, fibres and the like obtained by the spinning of solutions of proteins
Inventor: MCGILLIVRAY ROY
IPC: D01F4/00
Filed: 1954-05-05
Abstract: A process for insolubilizing a bundle of coagulated protein filaments comprises subjecting the filaments to the action of a compound which gives rise to a cyanate ion, such as urea, urea nitrate or sodium or potassium cyanate, either before or after the filaments have been treated with at least one hardening agent, impregnating the hardened filaments with a solution of formaldehyde, stretching the bundle of filaments by, for instance, 75-250 per cent, and preferably 200 per cent, heating them while stretched to dry them and then, when the filaments no longer tend to shrink, heating them further to effect insolubilization.  If the filaments are to be treated with only one hardening agent, that agent is preferably formaldehyde; if more than one hardening agent is used, the preliminary hardening stage or stages may employ aluminium sulphate or a sodium polymetaphosphate and the final stage formaldehyde.  The pH of the impregnating formaldehyde solution used to treat the hardened filaments may vary from 0.5-11, but preferably lies within the three ranges 0.5-2, 6.5-7.5 and 9.5-11, and the solution, which may contain 10-37 g. formaldehyde per litre, may also contain small quantities of hydrochloric acid, sodium hydroxide, sodium stannate, aluminate or borate, or ammonia or pyridine to adjust the pH to the required value.  The cyanate solution is preferably of pH 4-7 and of 1-30 per cent total salt concentration and at a temperature of 50-100 DEG  C. The filaments may be dried at 15-160 DEG  C. and then insolubilized at 120-180 DEG  C.  Specifications 513,910, 533,952, 597,497, [all in Group IV], 605,830, 623,460 and 642,359 are referred to.

Title: Liquid dispensing system
IPC: B67D7/22
Filed: 1958-04-28
Abstract: 914,651. Dispensing liquids. HENDERSON, W. D. July 14, 1959 [April 28, 1958], No. 13453/58. Classes 106 (5). and 116 [Also in Group XIX] In a self-service petrol station, a quantity and price indicator at the petrol pump is connected to a second indicator at a remote point and means are provided at the remote point for setting the indicators to zero. In Fig. 2, a number of self-service petrol pumps 6 is supervised by an operator at a remote control station 2 having a control desk 23 provided with indicators 24 associated with corresponding indicators at the pumps. Lifting of a pump nozzle 37 off its stand causes actuation of a servomotor 52, Fig. 5, which moves lever 50 to switch on the supply pump, lever 50 simultaneously rotating anti-clockwise a shaft 70, Figs. 8 and 10, associated with the indicator 100 on the pump so that pawl 75 on a plate 77 engages notch 78 in cam 72. When the nozzle is replaced on completion of delivery, the lever 50 and shaft 70 are returned and plate 77 is thereby rotated to look the computer wheels 60, a second pawl 82 engaging a notch 83 on plate 73 to prevent operation of the pump until resetting has been completed. The indicator 24 on the operator's desk is actuated by an electrical indexing device from the pump indicator. After receiving payment through a pneumatic tube system 10, 11, the operator resets his indicator 24 by means of knob 26 and depression of a second re-setting button 30 operates a solenoid 93, Fig. 5, to rotate shaft 84 to trip pawl 75, whereby the locking disc 77 is returned by a spring 79 to zeroize the pump indicator and the pawl 82 frees the disc 73 to permit the pump to be operated when the nozzle is next lifted from its bracket. An electrical circuit, Fig. 14 (not shown), for operation of the operator's indicator 24 from the pump indicator includes means preventing operation of the re-setting solenoid 93 until dispensing is completed. A lubricating oil dispensing device 180, Fig. 15, at each petrol pump comprises a spring-loaded piston which is forced upwards by the oil supplied under pressure through pipe 14 containing a valve 185 the opening of which is controlled remotely by the operator. To pull the cylinder the operator presses button 192 which operates solenoid 190 to open valve 185. When the cylinder 180 is full the piston operates main switch 186 to break the circuit of solenoid 190 and close valve 185. The measured quantity of oil is forced through pipe 16 to a dispensing nozzle by the spring 183 when the valve in the nozzle is opened.
Patent GB-583957-A (GB)
Title: Improvements in or relating to electrical induction apparatus
IPC: H01F27/25
Filed: 1944-07-14
Abstract: 583,957. Transformers. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. July 14, 1944, No. 13483. Convention date, July 20, 1943. [Class 38 (ii)] The core structure of a three-phase induction apparatus such as a transformer comprises a number of core loops each formed from a sheet of magnetic material wound flat-wise layer on layer, the individual layers being separated by adherent layers of insulating material. The cores are preferably formed of a ribbon of sheet metal such as silicon steel which has been rolled so that the grains are oriented in the direction of the magnetic flux. Fig. 2 shows part of a transformer in which three coils surround the limbs of four core loops each consisting of a number of laminations formed by winding a steel strip into a number of turns. The layers are bonded together by insulating material applied to both sides of the strip and the cores are then cut along a line 8 to enable the windings to be placed in position, the butt joints of the cores being formed as described in Specification 540,662. Fig. 4 shows an arrangement of three coils surrounding the limbs of three core loops each consisting of a wound strip of metal. In order that the cores may fill the openings in the coils which are of circular shape the layers 17 and 22 of the cores are narrower than the remaining layers. The coils may alternatively be of rectangular shape and the numbers of layers in each core may be such that the cross-sectional area of the cores is the same. The cores may be sufficiently narrow as shown in Fig. 14 to enable two additional cores 51 to be linked with each winding at right angles to the main cores. Additional cores 54 may also be provided on the end windings. Fig. 17 shows a modification in which the three windings A, B, C of a polyphase transformer are surrounded by two sets of strip cores each consisting of inner loops 64, 65, 66 surrounded by an outer loop 67. The polarity of the middle winding B may be reversed so that the flux passing between the coil groups is reduced. Figs. 18, 19 show a further modification in which the core loops are built up from steel strips which are narrower than the full width of the loops. The loops 85, 86, 87 shown in Fig. 19 are made from steel strip of the width shown at 81 in Fig. 18. Adjacent to these loops is the loop 91 which passes through all three phase windings. The construction is repeated with the next two layers 83, 84 to complete the full width of the cores. As shown in Fig. 19, below the core loops 85, 86, 87 is the single loop 88 passing through the three windings. Next to this loop are three loops 92, 93, 94 which are below the single loop 91, the alternate construction of core loops being repeated to complete the full width of all the cores.
