Filed: 1962-09-15
Abstract: 1,002,606. Valves. BLACK AUTOMATIC CONTROLS Ltd. Aug. 20, 1961, @ Sept. 15, 1962], No. 25246/62. Heading F2V  A solenoid operated valve comprises a valve actuating plunger 13 of magnetic material slidable in a guide sleeve 8 mounted externally of the solenoid coil 1 on pole pieces 3 and 4 extending laterally from opposite ends of the magnetic core of the coil. The ends of the tube 8 are closed by members 9 and 9a which comprise valve seats 11 and 11a and pipe sockets 12 and 12a. The plunger comprises a valve washer 14, axial bore 18 and radial port 17. A reduced diameter on the plunger provides a clearance for a compression spring 16 and a fluid flow passage. A non-metallic sleeve 19 co-operates with a shoulder 20 on the plunger 13 to define the plunger's limit of travel. In operation, when the coil 1 is energized the valve 14 is held closed, against the action of the spring 16, as the coil is de-energized the plunger 13 is moved by gravity and the spring 16 to open the valve so that fluid can flow past the seat 11, through the clearance housing the spring 16, through the port 17 and bore 18 to the outlet 12a. The operation of the valve may be reversed by inverting the plunger 13 so that the valve washer 14 co-operates with the seat 11a. The valve can be made to operate as a three-way valve by placing valve washers 14 at both ends of the plunger 13 and placing a side port in the wall of the sleeve 8. Instead of constituting the valve element the plunger may control a separate valve element through a mechanical coupling. The bore 18 may be replaced by axial grooves in the sliding surface of the plunger 13 or sleeve 8.

Abstract: 1,237,475. Silver halide photographic material supports. FUJI PHOTO FILM CO. Ltd. July 14, 1969 [July 25, 1968], No.35368/69. Heading G2C. A process for the production of light-sensitive silver halide material or a silver halide diffusion transfer method receiving sheet comprises swelling the surface of a plastics film with a liquid swelling agent, treating the surface of the film thus swelled with a non-swelling liquid miscible with said liquid swelling agent to coagulate the swelled portion of the surface, and applying thereto a light-sensitive silver halide emulsion layer or an emulsion layer containing development nuclei for use in a silver halide diffusion transfer method. Many plastics films and liquid swelling agents are listed. The non-swelling liquid may be an alcohol, an aqueous alcohol, an ether, a hydrocarbon or hexanone or a mixture of two or more thereof. The non- swelling may contain water in an amount sufficiently small that phase separation of the liquid does not occur, in order to improve adhesion of the layer to the support. A layer containing a pigment or a dye may be applied to the coagulated layer before said emulsion layer is applied thereto. The non-swelling liquid extracts the swelling liquid from the material leaving inumerous fine pores, thereby increasing the scattering of light at the surface and making the film surface opaque and simultaneously forming a matted or blushed surface by shrinkage upon coagulation. A material like paper in appearance and surface properties is obtained.

Title: Electric impulse transmitter
IPC: H04M1/34
Filed: 1937-12-24
Abstract: 508,474. Impulse transmitters. SCHYTTE, W. R., RICHTER, M. B., and TELEFON FABRIK AUTOMATIC AKTIE-SELSKABET. Dec. 24, 1937, No. 35772. [Class 40 (iv)] In an impulse transmitter in which the impulse springs are intermittently opened during the return movement of -a cam disc coupled to the finger plate, in order to allow for inertia in the receiving apparatus the first impulse of a train is made of longer duration than the remainder by means of a member which either extends the first impulse or shortens the subsequent impulses. The impulse springs 5, 6 are controlled by a shoe 9 on a spring 8 which engages the projections 4 of the cam disc 2. In the normal position the springs are closed by the engagement of the spring 8 with an extended projection 10, and during the setting movement the projections 4 engage a tooth 14 on a disc 13 and swing a member 11 having a pin-and slot connection with the disc into the position shown in Fig. 2, in which it engages an extension 17 of the spring 8 and holds the springs 5, 6 closed. An auxiliary cam member 29 which lags slightly behind the cam disc 2 takes over the function of the projection 10 until the member 11 becomes effective. In Figs. 1, 2, at the same time as the member 11 is moved, a member 25 which straddles a boss 26 on the cam shaft is swung thereby to bring an arm 23 into a position to engage the outer one of the springs 5, 6, so that they are opened to initiate the first impulse when the member 11 is withdrawn at the commencement of the return movement while the spring 8 still engages a projection 4 of the cam disc, with the result,that the first impulse is correspondingly lengthened. In Fig. 5, the arm 23 is integral with the member 11. and the extension 17 of the spring 8 is spaced laterally from the springs 5, 6. In further modifications of this arrangement, the arm 23 is pivoted on the member 11 and moves between stops thereon. In Figs. 10, 12, the controlling spring 8 is influenced also by a second cam disc 38 (indicated in dotted lines) which is identical with the cam disc 4 and has frictional engagement therewith as well as being coupled thereto by a pin 41 and slot 42. During the setting movement, the disc 38 is driven frictionally. until a projection 39 strikes a resilient stop 40, after which it is driven positively with its projections 39 in register with those of the disc 2. During,the return movement, the relative positions of the discs are maintained until a projection 39 strikes the stop 40, after which the disc 38.is driven positively with its projections slightly behind those of the disc 2. The stop 40 is struck at the time when the spring 8 in engagement with a pair of projections 4, 39 after the first impulse has been sent, and therefore each subsequent impulse is initiated slightly later than it would be under the control of the cam disc 2 alone.
