Abstract: 380,190. Starting prime-movers ; electromagnetic switches ; contacts. THORNE, C. G., 7, Kingscliffe Flats, 90, Milson Road, Cremorne, New South Wales, and DANGAR, GEDYE, & CO., Ltd., 10. Young Street, Sydney, both in Australia. July 6, 1931, No. 19465. [Class 38 (iv).] Relates to apparatus for automatically starting or stopping a prime-mover driving, e.g. refrigerator plant, which is responsive to conditions in the plant driven. Starting operations are initiated by the closure of a switch 5 responsive to conditions in the plant (e.g. controlled by a thermostat), which connects to the battery 4, the operating coil of a switch 7 which opens a -short-circuit in the ignition circuit, and the operating coil of a starting switch 17 which connects a motor 1 to the battery for starting the prime-mover. When the prime-mover starts it commences to drive the machine 1 as a generator, and a coil 22 on a double contact relay 13 is energized and draws an armature down against the action of a spring, contacts 14<1>, 14<2> separate and break the circuit of the operating coil of switch 17 which opens, but the circuit from the generator 1 is maintained by contacts 15<1>, 15<2> closing so that battery charging takes place. If the prime mover does not start in a given time a thermostatic switch 26 closes and causes a switch 12 in the battery supply circuit to be tripped. Fig. 4 shows the construction of a combined ignition and starting switch. A spool 51 carries the operating coils 17 and 7 of the starting and ignition switches respectively. The space 55 is partly filled with mercury electrically connected to a terminal 56 and floating in the mercury is a soft iron float 59 which is dragged down when the coil 17 is energized so that the mercury is forced up to contact with a stud 18<2> mounted on an insulating block 57. Mounted on the block 57 is a soft iron ring armature by means of a spring 63 which maintains the contacts 81, 8<2> closed. When the coil 7 is energized the armature is attracted and' its contacts separated. A construction of double contact relay is also described.

Title: Improvements in and relating to an electromagnetic valve
IPC: F16K31/40
Filed: 1955-07-18
Abstract: 789,241. Valves controlled by auxiliary valves. DUBOIS, R. C. July 18, 1955 [July 19, 1954; July 5, 1955], No. 20769/55. Class 135. In a valve comprising a piston 8, Fig. 1, carrying a main closure member 7 and controlled by a pilot valve 15 which is actuated by an electromagnet 26, the piston and closure member are slidable on a tubular element 14 which forms part of a passage for fluid under the control of the pilot valve. The inlet 3 communicates through a restricted passage 12 with a chamber 9 which also houses a spring 19 acting on the piston 8 in the valve-closing direction, whilst the chamber 9 also communicates through ports 17 and the pilot valve controlled port 20 with the tubular member 14 which has openings 16 leading to the outlet 4. When the electromagnet is energized the pilot valve 15 is opened to allow fluid in the chamber 9 to escape to the outlet, thereby lowering the pressure above the piston 8 to cause the inlet pressure to open the main valve. In a modification, the pilot valve is arranged at the end of the tubular member 14 that communicates with the outlet 4. In another modification, the piston and main valve member are of hollow formation and the openings from the tubular element to the outlet are screened so that the flow past the main valve seating induces a lower pressure in the chamber above the piston. Instead of the pilot valve opening on energization of the electromagnet it may be arranged to close. Also, the tubular element, instead of being fixed, may be operable by the electromagnet whilst the member 15 is fixed. In a further modification, an additional valve member 62, Fig. 5, is attached by a tube 68 to the valve member 7 and is arranged to connect the outlet 4 with an exhaust when the valve member 7 is closed. The outlet from the pilot valve 15 through the tubular element 14 and ports 71 passes through a chamber 66 below the second valve member 62 and thence through an adjustably restricted orifice 72 to the outlet 4. By adjusting the orifice 72 the rate of operation of the main valve assembly may be controlled.
