Title: Improvements in arrangements for sealing wires into electric discharge vessels
IPC: H01J5/32
Filed: 1933-08-17
Abstract: 406,214. Sealing leading-in wires into vitreous envelopes. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.- (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen ; 11, Ehrenbergstrasse, Berlin.) Aug. 17, 1933, No. 22987. Convention date, Aug. 27, 1932. [Class 39 (ii).] In sealing leading-in wires into luminous electric discharge tubes and similar vessels, particularly such vessels made of quartz or hard glass which attain a high temperature in operation, a capillary tube 3, Fig. 1, is connected between the discharge vessel 1 and the true seal 2, and a packing-wire 4 is wound helically around that part of the leading-in wire passing through the capillary tube. Preferably the capillary tube is made to fit closely upon the helically wound packing wire by evacuating the capillary and causing it to collapse by heat. When two leading-in wires are to be sealed in at the same end of the discharge tube one of them may be used as a helically-wound packing-wire, the wires being insulated from each other by an insulating- coating, preferably an oxide. Alternatively, if the potential difference between the two leading- in wires is relatively large the capillary tube 3, Fig. 3, is surrounded by a second glass tube 8, one leading-in wire 6 being surrounded by a helical packing wire 4 within the tube 3, while the other leading-in wire 9 is wound helically to form a packing between the tubes 3, 8. Metal vapours generated in the discharge vessel condense in the capillary and tend to stop up the space between the inner wall of the capillary and the spiral packing wire, thereby protecting the true seal 2 from attack by metal vapour. This effect may be assisted by introducing a metal such as zinc into the capillary. The discharge tube may consist of quartz, with a seal portion of borosilicate glass which may be connected thereto in known manner by transitional glasses.

Title: Control valve for controlling the operation of a mechanism to be powered from a pressurised fluid supply
IPC: F15B13/04
Filed: 1975-05-27
Abstract: 1467603 Valves KOEHRING CO 27 May 1975 [26 Aug 1974] 23167/75 Heading F2V A valve 10, Fig. 1, for controlling the flow from an inlet port 20 to one or other of work ports 24, 25 connected to a reversible hydraulic motor 12, and from the latter to one or other of exhaust ports 28, 29 comprises a ported axially slidable control spool 18 containing a pair of axially slidable plungers 48, 50, each of which acts to maintain the pressure drop across spool 18 constant when the latter is moved from the neutral position shown. If such movement is rightwards, fluid from inlet 20 flows through spool ports 68 and, if the pressure is sufficiently high, urges plunger 48 leftwards against the bias of spring 66 to open spool ports 70 and permit flow to work port 24. Pressure in the latter is communicated via spool recess 72 and passage 74 to urge plunger 48 rightwards against the inlet pressure. Plunger 48 thus acts to maintain the differential between inlet and work port pressures constant, e.g. at 50 p.s.i. Simultaneously with the supply of fluid via work port 24 to hydraulic motor 12, the latter discharges displaced fluid via work port 25 and spool ports 78, 80 to exhaust port 29. Plunger 50 acts to maintain the differential between work and exhaust pressures constant. The roles of plungers 48, 50 are reversed when spool 18 is moved in the opposite direction from neutral to supply fluid to work port 25. Plungers 48, 50 also act as lock valves in the event of fluid supply failure. The valve 10 may form one of a stack of similar multiway valves 111 to 114, Fig. 6, each controlling flow from a common pump 22 to independent motors. When all the valves are in the neutral position a valve plunger 90 in the inlet section 88 to the stack by-passes fluid from pump 22 back to reservoir 86. Should one or more of valves 111 to 114 be moved from neutral then the highest working pressure is communicated via passages (148, 180, &c., Figs. 5, 7 to 10 not shown) and shuttle valves (182) in the stack to chamber 104 surrounding by-pass plunger 90 and thence through port 108 in the latter to urge the plunger closed and prevent by-pass to reservoir 86. Each of the valves 111, 112 includes a further spring biased plunger 120 the interior of which is subject via passage 150, chamber 132 and port 134 to the working pressure of the valve, in opposition to the inlet pressure in port 20. The plunger 120 acts as a priority valve ensuring that inlet fluid is only passed to a downstream valve in the stack when the demands of the valve associated with that plunger can be met.
