Title: Improvements in or relating to a solenoid powered operator particularly for fluid-control valves
Inventor: RAY WILLIAM ALTON
IPC: F23N1/00
Filed: 1960-01-25
Abstract: 895,401. Valves. GENERAL CONTROLS CO. Jan. 25, 1960, No. 2709/60. Class 135. [Also in Group XXXV] A solenoid-operated valve for controlling the supply of fuel to a gas burner, comprises a casing 11 having a flow passage controlled by a valve 53, a solenoid device 18 mounted on the casing and having a plunger 33 operable in an open-ended tube 30 and biased to one end position by a spring 55 and to the other end position by an electromagnet 24, the plunger being connected to the valve by means of a rod 56, 57 and a rod 47 sealed in an opening 41 by means of a flexible bellows 42, a casing 17 surrounding the solenoid and, together with the bellows, forming a reservoir for a viscous liquid 60 communicating with each end of the tube 30, a check valve 35 co-operating with one end of the tube and having means to retard flow through that end when the solenoid is energized in order to open the valve member 53. The viscous liquid 60, which may be a silicone type of petroleum oil, is in communication with the right-hand end of the plunger 33 as shown, through passages formed between the outer housing 19 of the solenoid device 18 and the casing 17 and a restricted passage 39 provided in the check valve 35. In operation, when the solenoid is energized, the plunger moves to the left and thereby forces the viscous liquid through the restricted passage 39 thus retarding the opening of the valve member 53 ; when the solenoid is de-energized and the plunger moves towards the right under the action of a return spring 55, the check valve opens against the action of a light spring 36 and thereby permits rapid movement of the valve member to its open position. The restricted passage may be replaced by a metering notch 66, Fig. 3, not shown, formed in the end of an adjustable screw.

Title: Improvements relating to Electrostatic Machines.
Inventor: MORRIS DAVID KING
IPC: H02N1/00
Filed: 1917-02-24
Abstract: 117,821. Morris, D. K. Feo. 24, 1917. Influence machines.-In one construction, Figs. 1 and 2, two sets a, b of concentrically arranged sheet or strip-metal conductors are employed, these being carried by bars f, g, between insulating frames c, d, either or both of which are rotatable. The conductors of both systems are inclined to the gap surface between the conductors, and are so shaped that when their adjacent edges coincide, each pair forms a nearly continuous surface corresponding in configuration with the equipotential surface of a free oblique field between the two systems. The curvature of the conductors is that of a logarithmic or equiangular spiral, the radius of curvature at any point being proportional to the distance of that point from the axis of the machine. The number of conductors belonging to either system may be widely varied. In the limiting case shown in Fig. 3, a cylinder of insulating material c rotates within a pair of conductors a, one positive and the other negative. The one terminates in a surrounding metal cylinder h, whilst the other is attached to a bar i insulated from but fixed relatively to the cylinder. To avoid " stray capacity " between the conductors a, b, Figs. 1 and 2, the clearance between each adjacent pair is made greater at the ends than at the middle, as indicated by dotted lines in Fig. 1. In the machines illustrated, no collectors are provided, the machines discharging into the surrounding air when sufficient voltage is attained. The charges may be collected from conductors by suitable connexions as they pass under a reversing field. To restrict the voltage built up by the machines, an earthed ring e, Fig. 2, may surround the outer system.

Title: Improvements in and relating to Shutters for Searchlight Projectors.
Inventor: STEELE LOUIS JOHN
IPC: F21V17/02
Filed: 1918-02-21
Abstract: 130,427. Steele, L. J. Feb. 21, 1918. Lantern shutters.-A shutter for a searchlight projector is constructed of a pair of blinds of the roller-slat type adapted to be simultaneously moved together into the path of the search-light beam, and similarly drawn apart, by suitable power-transmitting mechanism, the blinds being arranged so that, when in the vertical or closed position, they balance each other. The blinds are mounted within a casing 1, Fig. 2, between the glazed front 10, 11 and the back ring 8, which fits into the front of the projector, and are carried by upper and lower shafts 35, 36, which are so geared together, as by the sprocket-chain mechanism shown, that the rotation of one effects the rotation of the other in the reverse direction, thus causing the blinds to be simultaneously moved together or drawn apart. When drawn together, so that the shutter is closed, the blinds mutually balance each other. The tension of the sprocket chains can be adjusted, when desired, by means of the free sprocket-wheels 14, which are mounted on adjustable eccentrically-pivoted supports. The operation of the shutter is effected by a sprocket chain or other suitable mechanism applied to the lower roller 36, the movement of which is limited by a stop 26 engaging a buffer 22. Fig. 4 shows a suitable construction of the roller-slat blinds, which are impervious to light but not to air. They are built up of a series of metal slats 52 bent to C-shaped section and slid together endways. To prevent lateral displacement, the ends of alternate slats may be bent at rightangles. The edge of one blind is formed with a recess 53 adapted to receive a tongue on the edge 54 of the other member, and, preferably, an additional strip 55 is provided to cover the junction. The guides or runners for the edges of the blinds consist, as shown in Fig. 8 and 9, of a brass strip 12 and a piece of tubing 56 mounted on a bent sheet support 57. The strip 12 is cut across the middle and sprung out slightly, as at 58. Fig. 8, so as to grip the blinds when they are in the closed position.
