The coil is wound either from a single wire or a plurality of wires 21 with an interleaving of an elastomeric sheet 25, Fig. 7, about a former 24, which may be polygonal in cross-section, Fig. 15 (not shown). A double layer coil (30), Fig. 9 (not shown), may also be wound and wires (31) of one layer are staggered with respect to wires (32) of the other layer. A multi-layer coil (35), Fig. 11 (not shown), is wound from a single wire (36) with the adjacent turns of wire spaced axially by an elastomer strip (37) and the successive windings are stepped axially so that the wire turns (36) in one layer abut the strip (37) in adjacent layers, which strip may alternatively be round in cross-section and of greater diameter than the wire. The coil may also be wound from insulated wire (52), Fig. 16 (not shown), with the turns of adjacent layers (53), (54) and (54), (55) leading in opposite directions to form a multi-layer mesh forming a flow space (58), (59), (60) between the turns of the coil. The turns are potted by injection or vacuum moulding using an uncured elastomer resin. In a further embodiment, Fig. 17, a core 62 is provided with radially projecting spacers (63), Fig. 18 (not shown), in axially spaced groups 64. First coils 65 are wound between alternate groups 64 and spaces 66 between the coils 65 are filled with elastomer by winding or potting. Second coils 67 are wound over the elastomer filling and spaces 68 filled with elastomer. When cutting a connector matrix from the potted coil the contact surfaces are cut in the spaces between adjacent spacers (63). The groups 64 of spacers may be replaced by annular foil spacers and a foil tape may be wound above and below each coil layer. The coils may include non- conducting spring turns and when the coil is cut through the spring elements are cut back. The coil is used with a pair of printed circuit boards (78) mounted back-to-back, Fig. 20 (not shown), the coil being generally of C-spring form. The ends of the wires may project beyond the faces 4, 5 and be plated with gold or tin.

Patent GB-1100467-A (GB)
Title: Control means for fluid pressure responsive devices
Inventor: WARNE EUGENE HAROLD
IPC: F02K1/15
Filed: 1965-02-04
Abstract: 1,100,467. Fluid-pressure servomotor systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Jan. 21, 1966 [Feb. 4, 1965], No.4834/65. Heading G3P. [Also in Division F1] The hydraulic power devices 10 operate a variable-geometry exhaust nozzle of a gas turbine engine (not shown) in response to a signal received by an actuator 15. The signal can be derived from compressor pressure, jet pipe pressure, or the throttle setting of re-heat apparatus. The actuator 15 operates a spool valve 14 controlling the supply and exhaust of hydraulic fluid to and from the devices 10. The fluid is supplied by a pump 11 driven by the turbine. Fluid from the supply line 12 is spilled through a valve 22 responsive to the pressure drop across the valve 14, so that this pressure drop is kept constant and hence the devices 10 are directly responsive to the signal in magnitude and speed of movement. The spill valve comprises a diaphragm 27 subject on one side to the supply pressure through a pipe 23, and subject on the other side, through a control conduit 24, to the pressure in whichever one of the two conduits 16, 17 connected to opposite ends of the power devices, is at the higher pressure. This higher pressure is selectively applied to the diaphragm through a pressure sensitive shuttle valve 21. The control valve 22 may be modified to vary the response characteristic. In one modification where the rate of spill is directly proportional to the rate of change of pressure at the downstream side of the valve 14, the diaphragm actuates a spool valve (33) having one land, Fig. 2 (not shown). In another modification to provide an increasing spill at a higher rate than the rate of change in the pressure, this spool (33) is replaced by a spool (34) having two lands between which fluid can pass to exhaust 29. The ends of the spool are subject to pump inlet and outlet pressure respectively. In a third modification to provide decreasing response, the pressure from the control conduit 24 is applied both to the diaphragm and to one end of a two-landed spool (39), Fig. 4 (not shown). The spill passes between these lands and the other end of the spool is subject to pump inlet pressure.

Title: Improvements in or relating to time-controlled dispensing devices particularly for the supply of gas
IPC: G07F15/12
Filed: 1936-02-17
Abstract: 470,759. Coin - freed apparatus for delivering electricity, gas, &c. AIR LOG CO., Ltd., and MAYERS, H. C. Feb. 17, 1936, Nos. 4841 and 22987. [Class 27] Time - controlled apparatus.-A coinfreed apparatus for the supply of gas or electricity on a time basis comprises a clockwork motor the spring 18, Fig. 1, of which is wound, after insertion of a coin, by the rotation of twin handles 37. During the winding, one member 24 of an epicyclic gear is rotated through gearing 25, 26 from the winding spindle 15, a second member 22 being actuated by the running down of the clockwork, the going-barrel 19 of which is geared thereto by wheels 20, 21. The planetwheel 27 of the epicyclic gear is carried by a shaft 23 which drives through gearing 28, 29 a cam disc 30 co-operating with a pin 31 on an arm 32, Fig. 8, fixed to the shaft 72 of the supply valve 71, 74, Fig. 7. The cam 30 has a notch 76 towards which the pin 31 is pressed by a leaf spring 75, when the disc 30 is returned by the clockwork motor towards its gas shutting-off position. The spring 75 is insufficient to move the pin 31 to the bottom of the notch 76, this being done by the continued rotation of the disc. To allow a large number of coins to be used at a time, a second cam disc 77 driven by gearing 78, 79 from the shaft 23 and provided with a notch 83, controls an arm 80 pivoted at 81. The disc 77 makes one revolution for several revolutions of the disc 30 and causes the arm 80 to push the pin 31 away from the periphery of the disc 30, so that this pin cannot enter the notch 76 until both cams have been returned to their zero position. The spring motor drives the gear member 22 under the control of an escapement mechanism having a balance wheel. A manually-operated tap 69, Fig. 7, is provided to allow the user to stop the gas supply at will. The spindle connecting the handle and the tap 69 is fitted with a cam which is utilized for starting and stopping the clockwork motor. The mechanism for this purpose is arranged as described in Specification 422,849. Means are also provided in this starting and stopping mechanism for allowing the proprietor to cause the clockwork motor to run down and zeroize the mechanism without the tap 69 being turned on. In a modification, the clockwork motor runs down under the control of the gas flow instead of an escapement, so that the duration of the supply depends partly on time and partly on the rate at which the gas is being consumed. Coin-action, thrust; price-change mechanism.- A coin inserted through a slot in an adjustable plate 59 into a coin holder 39 moves a finger 35 into engagement with a ratchet wheel 16 on the winding shaft 15, a pawl 17 preventing backward rotation of the ratchet wheel. The plate 59 is angularly adjustable in position according to the amount the clockwork motor is to be wound for each coin.

Abstract: 494,149. Pads. TRIGGS, W. W. (Pad- Y-Wax Co., Inc.) Feb. 18, 1937, No. 4882. [Class 19] Wax polishing pads are made of nitrated cellulose or other sponge material rendered impervious to wax and wax solvents on one face and impregnated with a charge of wax and wax solvents. The openings in the pads are made as large as possible to retain the wax, a maximum size of about # inch being preferred. A large layer of sponge is cut up into a number of pads. The sponge is ordinarily harsh but may be rendered soft by water. The back of the sponge 10 is made impervious to wax and solvents by being coated with nitro-cellulose lacquer which may be fed on to it from a container as indicated at 11, Fig. 1, and made level by a scraper 12. While still wet, handles 13 may be placed upon it which stick as the lacquer dries. Softening of the sponge is obtained by passing it under a spout 19, Fig. 2, for applying a solution of glycerine and water. Superfluous liquid is squeezed out by rolls 20. Wax is applied from a filler 21 and excess removed by a scraper 22. A finished pad is shown at Fig. 4. Slight variations in the form of handle may be made and the whole may be packed in material known under the Registered Trade Mark "Cellophane."
