Title: Improvements relating to valves of the so-called equilibrium type
IPC: F16K39/02
Filed: 1921-03-10
Abstract: 177,385. Chorlton, F. O. L. March 10, 1921. Closure members, double beat lift. - A double or multiple beat valve is provided on one face with a rod of predetermined section to balance the pressures, and with a spring that comes into action after partial opening to neutralize the effect of the rod. The valve b that controls the passage of fluid from the inlet c to the outlet c<1>, is subject, during the initial stages of its opening, to a force tending to close it, and this is balanced by the provision of a rod e which reduces the ar@ of the member b<3> on which the pressure acts. This force decreases during the later stages of the valve opening and the flange e<1> on the rod then comes into contact with a disc e<2> resting on a spring g, so that the resistance of the spring neutralizes the effect of the rod e which is then undesirable. The rod e may be the actuating-rod, or may be independent if an actuating-rod on the opposite side of the valve be used.

Abstract: 346,933. Combined switch and plug couplings. LœDENSCHEIDER METALLWERKE AKT.-GES., VORM. J. FISCHER & BASSE, L³denscheid, Westphalia, Germany. March 8, 1930, No. 7632. Convention date, Feb. 18. [Class 38 (i).] A combined switch and plug coupling has a lever system coupled to the switch dolly which operates a rotatable disc, whereby when the plug member is not inserted, the sockets are covered, whilst when the plug member is inserted a bolt is operated to secure the plug against removal. The lower end of the dolly a passes through a hole in a slide b provided with an arm c. A lever f pivoted at k has a pin and slot connection at h with the slide b. A lever i also pivoted at k is connected by a spring s to the lever f, and carries a pin n which engages a slot in a disc m mounted to rotate above the plug sockets d. If no plug is inserted in the sockets d and the switch is in the " on " position as in Fig. 3, the slide b is in the lowest position, thus turning the levers f, i to rotate the disc m so as to cover the sockets d and prevent the insertion of a plug. When the switch is in the " off " position, the holes in the disc m register with the sockets d and a plug may be inserted. If now the switch is turned on the arm c is moved downwards by the slide b and enters a recess in a pin of the plug member, thus preventing the removal of the plug. The spring s allows the switch to be moved without rotating the disc m, while a plug is in position in the socket.

Abstract: 453,507. Coating glass &c. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and FAIRBROTHER, J. A. V., 110, Eastlands Road, Rugby. March 12, 1935, No. 7690. [Class 93] [See also Group XX] Surfaces such as glass, for example those used in electric discharge apparatus, are coated with a fluorescent powder, such as zinc silicate, by first applying to the surface an etching solution, containing for example dilute hydrofluoric acid, which reacts with the surface to produce an adhesive gel layer, removing excess of the solution, applying the powder as by spraying or dusting on, and drying the surface as on a hot plate or over a flame.

Title: Apparatus for growing single crystals of quartz
IPC: C30B7/00
Filed: 1951-04-03
Abstract: <PICT:0761531/III/1> <PICT:0761531/III/2> Apparatus for growing quartz crystals comprises a pressure vessel having silicadissolving and quartz-growing regions and a plurality of restricted channels interconnecting said regions with a fluid medium in the vessel for dissolving the silica and depositing as quartz on seeds in the growing region, means being provided for maintaining the fluid medium under elevated temperature and pressure conditions in the quartz growing region and under still higher temperature conditions in the silica dissolving region.  Preferably, means are provided to move the vessel cyclically to vary the convective flow.  The growing conditions and aqueous fluid are generally as described in Specification 682,203.  As described the pressure vessel consists of two chambers 24, 27 joined by two or more tubes 71, 72.  In a modification (Fig. 4, not shown), four tubes are provided between the chambers 24, 27.  Chamber 24 contains silica nutrient, e.g. quartz chips 26, confined by screens 90, chamber 27 containing one or more quartz seeds 28, 29, 31 held in a suitable framework.  The chambers 24, 27 and tubes 71, 72 are surrounded by wire wound electric heaters and enclosed in insulating jackets. Thermocouples 51, 56, 63, 64, 92, 94 measure the internal or surface temperatures of the chambers and tubes.  The whole assembly is mounted on a table 11 which can be rocked about a mean horizontal position by a motor 16.  Fluid flows through whichever tube 71 or 72 is uppermost from chamber 24 to chamber 27 by convection.  The regular reversing of the direction of flow tends to maintain constant the temperatures in the two chambers. If the temperature is below the initial temperature of the solution, the transfer of the vapour bubble in each chamber from one end to the other as the table 11 rocks also assists in maintaining the temperature constant by mixing the fluid in the chamber.  Liners of graphite may be inserted in the growing chamber 27 to restrict its cross-section to that area and shape most effective for growth.  This may be square or, as shown in Fig. 7, the space defined by the inner surfaces of the liners 121, 122 accommodating seeds 123-127.  The seed holders may be as described in Specification 761,532. Specification 761,643 also is referred to.

Title: Improvements relating to electric meters
IPC: G07F15/00
Filed: 1945-03-28
Abstract: 589,723. Supply meters. DYSON, J. E., kind DELANEY, J. March 28, 1945, No. 7853. [Class 37] In order to make the speed of the rotor a dependent on the supply voltage, the current coil g is connected to a winding i round a limb j of the voltage magnet e instead of to the supply circuit, this winding acting as a transformer secondary winding in conjunction with the voltage coil f. The speed of the rotor is thus made dependent on the supply voltage and this being constant results in a constant rotor speed. The rotor operates a meter switch c in the supply circuit through tripping mechanism after a predetermined time independently of the rate of consumption during this time. The meter may be employed as a prepayment meter for billiard table lighting, for fires in hotels, or for other time services.

Abstract: 995,647. Platform elevators; safety catchgear. A. LOELIGE. Feb. 28, 1962, No. 7890/62. Headings B8H and B8L. [Also in Division B7] In a trolley comprising a chassis 1 provided with raisable and lowerable wheels 4, 5 and with a mast 10 guiding a vertically movable platform 9, the wheels may be lowered to raise the chassis from the ground by the platform 9 as it reaches the bottom of the mast 10. As shown, Fig. 1, brackets 3, supporting wheels 4 and pivoted to the chassis at 2, are connected by a link 25 to a lever 24, which is pivoted to the chassis, and a bracket 6 supporting a steering wheel 6 is vertically movable on the chassis and is connected to the lever 24 by pivoted links 28, 26. As the platform 9 is lowered, a member 22 thereon engages a roller 23 on the lever 24 and pivots the lever in an anticlockwise direction, thereby lowering the wheels 4, 5. The roller 23 may be moved out of the path of the member 22. A catch 32 is pivoted on the chassis so that the lever 24 may be locked in its lowered position. In a modification, Fig. 3 (not shown), the lever 24 is adjustably connected to the links 25, 26 whereby the amount by which the wheels 4, 5 are lowered when the platform 9 is lowered may be varied. In a further modification, Fig. 4, a strut 42 provided with a pivoted ground-engaging shoe 44 is pivoted to the lever 41 and rests against studs 45 when the wheels are raised so that, as the platform 9 pivots the lever 41, the strut 42 pushes the trolley along. The wheels 4, 5 may, alternatively, be lowered by hydraulic means controlled by the platform 9 through a lever or plunger. Catch gear.-A lever 15, Fig. 1, provided with brake shoes 14 adapted to engage the mast 10 and with a slot 16 engaging a pin on a post 12 on the platform 9 is connected by a link 17 to a member 18 which is pivoted to a second post 12 and which supports a pulley 20 for the platform-raising cable 21.
