Title: Improvements in and relating to hydraulic presses
IPC: B30B15/16
Filed: 1946-07-01
Abstract: 623,401. Hydraulic presses. ERNST, W. July 1, 1946, No. 19674. [Class 69 (ii)] Fluid flow to a hydraulic press ram is controlled by a valve 19, the position of which is adjusted by fluid pressure through the solenoidactuated valves 40, 47, 49 and 54, these being operated from an electric circuit. When the starting switch 73 is operated, solenoid 72 moves valve 40, pressure fluid from pipes 55, 38 moving valve 19 so that liquid below the piston 2 escapes to exhaust whilst the piston descends by gravity. When switch 115a is contacted, valve 47 is actuated to move valvo 19 so that pressure fluid is supplied above the piston 2. Pressure fluid supply is stopped either when the total load exceeds a limit, or the switch 119 is operated by the cam 92. In either case valve 54 is' actuated to shift the control valve 19, supplying pressure fluid for retraction. Press movement can be stopped at any point in the stroke by the switch 131, and reverse movement can be initiated at any time by switch 122. If leakage occurs with the ram in its retracted position, allowing ram to descend, switch 91 reverses valve 47 and supplies a small quantity of pressure fluid through lines 55, 57, 48, 43 and 66 to lift ram to original position.

Title: Improvements in magnetic control apparatus
IPC: H03K19/16
Filed: 1958-06-24
Abstract: 859,022. Non-contact-making relays. GENERAL ELECTRIC CO. June 24, 1958 [June 25, 1957], No. 20189/58. Class 40 (9). Unidirectional pulses are gated to a load in a circuit which includes a winding common to two cores each having an independent controlwinding. If the control windings magnetize the cores in opposition to the load pulses then the presence of an input to either or both control windings prevents energization of the load as the load pulses are absorbed in turning the core or cores over. A constant bias may be applied to one or both cores to act in opposition to load pulses and the control windings may then be energized to cancel the bias so that the presence of one input and the absence of the other, or the presence of both inputs is necessary before the load is energized. A number of control windings may be used on each core so that an input to any one or to any predetermined combination is effective to permit or deny energization of the load. Up to ten cores may be used with a common load winding and control windings individual to each core. In Fig. 14 is shown an AND gate 60 followed by a BUT NOT gate 40 which control the energization of a load 101 from a power supply 100 depending upon the switches 102, 103, 104. A saturable transformer 111 and a thyrite disc 118 connected to rectifier 112 produce spaced power pulses to energize the common winding 14 of each gate. A rectifier 113 produces bias current which is applied to both cores of AND gate 60 and to core 12 only of BUT NOT gate 40. If both switch 103 and switch 104 are made to energize the control windings of AND gate 60 an output is provided to energize an input winding 25 of the BUT NOT gate and inhibit the flow of pulses over winding 14 to load 101. Due to the bias in winding 38 of the BUT NOT gate switch 102 must be made to energize input winding 36 before load 101 can be energized. The speed with which the cores are switched is increased by shunting the loads and part of the load windings by capacitors 43 and adding resistance in the load circuit. A plug-in assembly of the components necessary for BUT NOT gate 40 is illustrated, Figs. 4 to 6, not shown.

Abstract: 461,133. Making glass bottles. UNITED GLASS BOTTLE MANUFACTURERS, Ltd., and MOORSHEAD, T. C. Sept. 17, 1935, No. 20367. [Class 56] A press and blow machine similar to that described in Specification 281,383, [Class 56], in which the blank moulds travel at one time in an outer and at another in an inner arcuate path, has means whereby when they are travelling in the outer path they are brought into register with suction heads by which they are then depressed into a forehearth or revolving pot and filled. As a blank mould 22 approaches the gathering position, the arm 20 which carries it is swung outwardly with the aid of cam track 3a and rack and sector 6a, 7a, Fig. 5, until the mould is over the forehearth &c. Before or during this movement the mould halves are brought together with the help of cam track 23 and links and levers 26, 27, 28 and 31, Fig. 4. By the action of cam track 34 acting through racks and quadrants, the suction head 33, Fig. 2, is lowered on to the mould, forcing it into the molten glass against a spring 43, Fig. 7. At the same time, under control of another cam track acting through links and levers 52, 51, a valve is opened to apply suction to the mould. The part 57 seals the top of the mould, suction being applied through the grooves 22a, Fig. 4. The suction head then rises and a cut-off knife 8 on an arm 16, the height of which is adjustable by a hand-wheel 20a, to suit different moulds is swung across by a spring 17, Fig. 3, which has previously been compressed by the action of cam track 12a acting through rod 10a and sectors 9, 13a, 14a. The knife comes to rest with its recess 8a in register with the opening in the bottom of the mould, and remains in this position, supporting the charge. Midway between the two arcuate paths, the cut-off knife slides over a support screw 59 on an arm 60 and, owing to the engagement of a pin 80 with an adjustable stop 61, both arms move together until the mould is beneath a register head 58 and pressing plunger 63. The register head and the pressing plunger 63 are lowered, thus forcing the glass up into the neck mould 62. After this the plunger is raised and the blank mould is opened. The pressed parison is then transferred in known manner to finishing mould 65, while the blank mould is swung outwards to pick up another charge.

Filed: 1920-07-10
Abstract: 148,500. Luckweil, A. Oct. 1, 1917, [Convention date]. No Patent granted (Sealing fee not paid). Flat driving-ropes; machines for making.-Wide belts of twisted ropes are made by plaiting-in between two adjacent ropes of the belt a third twisted rope. The machine shown in Figs. 1 and 2 consists of a number of twisters a with bobbins p, a bobbin creel b being arranged between each pair of twisters, but at a higher level. The twisters a are on hollow shafts n, and are driven by a horizontal shaft d which drives through worm gearing f or equivalent gearing, vertical shafts g carrying gear wheels h, k. Each pinion k drives two wheels m, which are connected to or form the flanges of the twisters a, and are rotated in the same direction so that the twisters a all form ropes of the same twist. The bobbins s of the creels b move in curved tracks q, Fig. 2, each consisting of two sections q<1>, q<3> outside the areas of rotation of the twisters a, and two sections q<2>, q<4> intersecting those areas. Within the sections q<1>, q<3>, and partly within the sections q<2>, q<4>, the bobbins s are operated by drivers t', t<3>; within the sections q<2>, q<4> they are operated principally by the drivers t<2>, t<4>. The drivers t<1>, t<3> are actuated by the shafts g, g<1>, and the drivers t<2>, t<4> by the shafts o passing up through the hollow shafts p of the twisters. The strands on the bobbins p are led up through tubes w, which are carried round in guides x and pass through the tracks z. In the machine shown, three four-strand ropes with a left-hand twist are formed by the rotation of the bobbins p<1> to p
 &c. of the twisters I<a>, II<a> III<a>, and they are plaited together by the cords from the bobbins s of the creels I<b>, II<b>, III<b>, (rotating oppositely and producing cords with a right-hand twist), overtaking the cords from the twisters a during their passage through the parts q<2>, q<4> of their journey. The machine may be arranged so that the cords from the twisters move faster than and overtake the cords from the bobbins s; as shown the bobbins s make four complete revolutions for four half revolutions of the bobbins p, this being obtained by suitable wheel-gearing. The belt produced is shown in Fig. 5. The strand s<1> of the intermediate rope I<b> first over-plaits the strand p<1> of the outer rope I<a>, and the strand s<3> of the rope I<b> over-plaits the strand p' of the adjacent rope IIa. Then follow in succession the over-plaiting of the strands p<2> by s<2>, p<3> by s<3>, and p<4> by s<4>, and simultaneously the over-plaiting of the strands p<6> by s<4>, p<7> by s<1>, and p
 by s<2>. Cores may be twisted into the strands of the ropes in the usual way.
