IPC: F16K31/42
Filed: 1968-01-15
Abstract: 1,167,703. Valves. KYOEI KAIHATSU K.K. 15 Jan., 1968 [17 Jan., 1967], No. 2041/68. Heading F2V. A pilot-operated valve has a spool 1 slidable in a casing to selectively connect a pressure port P to either of working ports F, G. The spool is moved by pressure fluid admitted to chambers C1, C2 by solenoid-actuated pilot valves b2. The spool has annular grooves 3, 4 formed adjacent its ends which grooves communicate with the chambers C1, C2 respectively by passages 5, 6. Drain passages 9 in the casing connected directly to a reservoir allow fluid in the respective chamber C1, C2 to pass unrestricted out of the chamber as the spool end moves into the chamber until the part 1a or 1b closes off communication of the chamber C1, C2 with the respective passage 9. This occurs at the same time as the port P begins to open and allow fluid to flow to either port F or G. Thereafter fluid is displaced from the chamber C1, C2 through a restriction in parallel with a check valve.

Patent GB-859088-A (GB)
Title: Apparatus for electric motor control of linear movements of a levitating body
IPC: G01D7/10
Filed: 1957-01-21
Abstract: 859,088. Electric indicating systems. MUNZ, O. J. Jan. 21, 1957 [Jan. 23, 1956], No. 2066/57. Class 40 (1). [Also in Groups XIX, XXXV, XXXVI and XL (b)]  Apparatus for causing a stylus to trace a three-dimensional curve comprises a conductive or magnetic stylus supported in space by electromagnetic attraction or repulsion, or by electrostatic forces, the stylus being electrically charged and suspended in a fluorescent or phosphorescent gas, or filled with a recording medium and suspended in a transparent polymerizing plastic. Relative movement between the stylus and the medium container is produced by three signals, which determine the X, Y, Z co-ordinate movements. The three signals are individually fed to three servomotors producing corresponding movement of the medium container relative to the stylus in the X, Y, Z direction, or the signals are fed in push-pull to normally balanced symmetrical coils controlling the position of the stylus by mutual repulsion or attraction. A fourth signal representing e.g. time, may also be introduced to modify one or all of the signals. In one embodiment (Fig. 1) a stylus 5 of conductive material is supported in a recording medium 4 located in a transparent container 2 by the action of coils 23, 24, 25, the pairs of coils 23, 24 being fed with A.C. in opposition so that each coil repels the conductive stylus in mutually perpendicular directions, and coil 25 is A.C. energized to counterbalance the weight of the stylus. The control signals SX, SY, SZ are fed to servomotors (not shown) to produce corresponding movement of the container 2 along the X, Y, Z axes relative to the stylus. In another embodiment (Fig. 2a) the signals, e.g. 53A, are compared individually with a reference voltage 52 of the same frequency to produce push-pull output for differential energization of the pairs of coils 68, 69 to produce corresponding movement of the stylus 5. In a further embodiment (Fig. 3) the control signal 53B is fed to a servomotor 82 to drive a carriage 80 along a lead-screw 81, a balancing signal being obtained from the slider 88 of a potentiometer 89. The carriage 80 carries a lamp 83x and two photo-cells 86x, 87x located on opposite sides of the stylus 5, so that relative movement between the stylus and the carriage produces differential energization of the photocells to unbalance a measuring bridge 43, producing differential energization of coils 68x, 69x also carried by carriage 80, to reposition the stylus centrally between the coils, thus making the stylus follow the movements of the carriage 80 as determined by the control signal 53B. The control signals may be fed directly into the bridge 43 across one arm, when the resulting unbalance causes differential energization of the coils 68x, 69x to move the stylus 5 until the differential output of the photo-cells 86x, 87x neutralizes the effect of the signal input to the bridge.

Abstract: 414,060. Prepayment mechanism for gas meters. HILL, J., 59, Pritchett Street, Birmingham. Jan. 25, 1933, No. 2349. [Class 27.] Coin action, thrust and multiple-coin.-In gas meter prepayment mechanism having two toothed winding wheels concentrically mounted with an annular space between their teeth, a coin inserted through a slot in the front change plate f, Fig. 1, to a shoot h carried by a disc h<2> rotatable by a knob g, depresses a slide m against the action of a spring m<2> which slide contacts with and rocks, against the action of a spring j<3> a lever j pivoted at j<2> to the shoot h. If a shilling is used, a heel m<5> on the slide m engages a toe j<5> on one end of the lever and causes its other end j<4> to engage the teeth of a measuring-out or winding wheel d. When a penny is used an incline m<6> on the heel m<5> engages the toe j<5>, and causes the end j<4> to engage a concentric wheel c, while in the event of a half-penny being inserted the end j<4> is moved to a space l between the wheels. The mechanism may be set for single coin operation only by a plate n, Fig. 4, having a slit n<30> through which a peg m<3>, projecting from the slide m through a slot m<4> in the shoot h, passes. The plate is clamped in positions n<2>, n<3>, n<4> for optional shilling, and penny operation respectively. Gas, supplying.-A notched cam disc u actuates a valve-operating arm v, the disc being rotated in opposite directions from a meter shaft 6 and a coin-operated shaft t respectively, through worm gearings 6<a>, 6b and t<2>, t<3>. The shaft t is actuated from the wheels c, d through planet pinions, the carrier disc w of which is fixed to the shaft. These pinions mesh with loose sun wheels m, gearing respectively with wheels o, g which are connected to and rotate with the wheels c, d. When the penny wheel c is rotated, the shilling wheel d remains stationary but rotation of the wheel d also rotates the wheel c owing to a ratchet pawl z pivoted to the wheel d and engaging the wheel c. Backward rotation of the wheels c, d is prevented by pawls z, y.

Apparatus for turning inside out hollow flexible articles which are closed on three sides comprises turning grippers 20 which are rotatable about vertical gripper carriers 10 to pick up and grasp workpieces 38 and on their return movement turn them inside out and deliver them to clamps 58, 60 to be subsequently deposited in a magazine 66. In operation, an air jet lifts the front edge 42 of the workpiece 38 and the larger arm 25 of each gripper 20 enters between the layers of the workpiece through the only open side and the second arm 28 goes below the supporting table 44. The gripping arms 25, 28 are then closed on the workpiece and locked in the closed position. As the grippers 20 return towards the position shown in Fig. 1, the workpiece is turned inside out and in each case the smaller arm lies inside the workpiece. The grippers 20 can then be rotated about their longitudinal axes 11 to tension the workpiece and pull it into shape. The workpiece is then passed to clamps 58, 60 which are mounted on a pivoted frame 52. As the frame 52 moves away from the grippers 20, which have been opened by the abutment of a blocking lever 30 on a fixed stop, the workpieces engage on castellations 70 on the top edge of an open topped magazine 66 and are pulled from the clamps to fall into the magazine. If the workpieces are not properly located in the clamps 58, 60 from the grippers 20 the machine stops. The magazine is resiliently supported and takes workpieces until it is so downwardly displaced that a switch is operated to stop the machine. The table of the machine is in two parts 2,3 which can be laterally adjusted to accommodate different sizes of workpiece.
