Abstract: 1,158,805. Electromagnet. J. C. MACY. 2 Sept., 1966 [10 Sept., 1965], No. 39363/66. Heading H1P. An electromagnetic actuating device comprises a pair of end members capable of relative movement along a common path, a magnetic structure disposed between said end members so as to surround said common path, the configuration of said structure being such that it divides any existing gap between said end members measured parallel to said common path into a plurality of approximately equal increments, and electromagnetic means operatively associated with said magnetic structure for setting up a magnetic flux when energized, which magnetic flux changes the magnitude of said increments and causes relative movement of said end members along said common path. In one embodiment the device comprises a plurality of rings 10 each including an inner and an outer ring 11 and 12, a concentrically wound coil 14 and a pair of non-magnetic washers 15. Each ring 10 is separated from its neighbour by an air gap 45 but is coupled thereto by a coupling ring 20 through which runs a guide shaft 26. As shown in Fig. 1 the air-gap is at a maximum. When the air-gap is at a minimum the washers 15 are in contact. Iron end caps 30 have a coil 31 therein with a non-magnetic washer 32 and coupling member 34. A flexible bellows structure 40 surrounds the magnetic structure and is retained in place by rings 42. Rings 42, couplings 20 and 34 and rod 26 may be made of aluminium or brass. Each coil 14 may be energized in the same direction or adjacent coils may be energized in opposite directions thereby giving a contractive or expansive force. In an alternative embodiment (Fig. 4, not shown) the coupling members may be on the outside of the rings. In another embodiment (Fig. 5, not shown) a similar arrangement is illustrated but a cylindrical coil (50) is used mounted on springs (53, 63) in both end caps (52, 62) whilst two sets of rings (76, 78) are used, one set (76) within the coil (50) coupled together by couplers (77) and the other set (78) outside the coil, coupled with couplers (79). In a further embodiment, Fig. 7, two electromagnetic coils 110 and 111  are wound in the form of a double helix welded to end caps 120 and 121. Each coil consists of a conductive strip 112 between two insulating strips 113 and 114, with adjacent strips of magnetic material 115 and 116 and edge strips 117 and 118. Contractive or expansive forces are obtained by energizing the adjacent turns with opposing or like polarities via leads 122. A fluid or elastic material having ferromagnetic properties can be used to fill the gap between the turns. A simpler embodiment (Fig. 6, not shown) of similar construction has a single electromagnetic helix surrounding a guiding rod, wherein the electromagnet cores (94 and 95) may comprise iron particles in a flexible medium and the conductor (90) is a multiplicity of wires or a copper bar.

A tube 18 when moved upward after counterpressure is applied to the container 4, allows liquid to pass into the container through a liquid supply channel 14, the filling process being stopped when the rising liquid contacts the end of the gas pipe 20. Excess gas pressure is released through duct 29 and valve 30 and the pipe 20 may be adjustably connected to the holder 6 by means of a spring clip 23 to obtain different liquid levels in the container. After the container is filled an overpressure may be produced in the container relative to that in the pressure chamber, thereby causing the container to be released from the holder (105), Fig. 3 (not shown). Excess liquid in the channel (114) may be expelled into the container by gas pressure acting through a passage (147). The seal 10 may have rectangular, triangular or semi-circular inner or outer surfaces, Figs. 20-22 (not shown). Circular or semi-circular annular mouths 304, Fig. 15, of the liquid supply channel compensate for the movement of liquid in the container and liquid stream caused by the centrifugal force 320 arising from the rotational movement of the circular array of filling heads, as do spring clips 310 which may extend from the holder 305 to the gas pipe 314 only, or to the diametrically opposite part of holder 305.

Title: Fluid dispensing nozzle
IPC: B67D7/48
Filed: 1971-08-27
Abstract: 1371201 Dispensing fluids DOVER CORP 27 Aug 1971 [31 Aug 1970] 40334/71 Heading A4T [Also in Division F2] A gasoline dispensing nozzle has an inlet valve member 17 movable to an open position by lever 22 and an outlet valve member 18 secured to the end of spout 14 carrying a slidable collar 45 sealingly engageable with the mouth of a tank filling tube 16, the arrangement being such that the spout 14 moves through collar 45, when the latter engages tube 16, until spring 46 is coilbound, at which point the main body of the dispensing nozzle together with adaptor 27 move relative to the nozzle against spring 31 to unseat valve member 18. Should the spout be removed from the filling tube, valve member 18 is reseated by spring 31. With both valve members 17, 18 unseated, gasoline flowing to the spout past poppet 76 draws air through level sensing conduit 64, port 70 (aligned with passage 69 when valve member 18 is unseated) passages 67, 66, chamber 63, check valve 93 Fig. 9 (not shown) and ports 75 in seat ring 74. When the level of gasoline in the tank covers inlet 65 of conduit 64, the depression created above diaphragm 62 raises the latter to withdraw pin 78 from between latch balls 79, thereby allowing spring 19 to seat valve member 17. Vapour from the tank is withdrawn through port 48 (controlled by collar 45), along conduit 49 and through passages 51, 5 5 to a recovery conduit. If the latter should become blocked, the resultant pressure rise acts via passage 58 below diaphragm 60 to raise the latter, thereby withdrawing pin 78 and causing valve member 17 to seat. Coupling 87 transmits upward movement only of diaphragm 62 to diaphragm 60, and allows relative upward movement of diaphragm 60 as required when the vapour recovery conduit is blocked.
