Title: Improvements relating to electron discharge devices
IPC: H01J19/44
Filed: 1926-04-23
Abstract: 252,141. Westinghouse Lamp Co., (Assignees of Widell, E. G.). May 16, 1925, [Convention date]. Metallic-vapour apparatus. -In a photo-electric cell, rectifier, thermionic valve, or the like containing an alkali metal, leakage between the leading-in wires is prevented by coating the internal glass surfaces adjacent these wires with an organic substance on which alkali-metal films are not formed. Suitable substances are resin, shellac, and nitro-cellulose. Shellac may be applied to the stem 7 with the help of a vehicle such as alcohol, volatile matter being then removed by baking. Carbonization must be avoided during the sealing of the stem to the envelope and during baking of the valve &c. to remove occluded gas; a temperature of 275‹ C. is suitable for the latter process. The alkali metal may be distilled in from a side tube, or placed in a capsule; sodium may be in metallic form. but more active metals such as caesium and rubidium are used in the form of chlorides mixed with a reducing agent such as calcium. As shown, a capsule 15 is secured to the anode, so that it can be heated by high-frequency induction. A small piece 16 of magnesium or the like may also be attached to the plate and vaporized by the same heating so as to assist in cleaning-up residual gases. An electronegative gas such as nitrogen or carbon monoxide may be left in the tube to promote the formation of an active film on the cathode. The Specification as open to inspection under Sect. 91 (3) (a) states that instead of coating the glass, its composition may be varied to render it proof against the alkali metal. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to knitting machines
IPC: D04B11/00
Filed: 1939-04-06
Abstract: 527,708. Knitting-machines. BERRIDGE & CO., Ltd., I. L., and COLTON, L. H. April 6, 1939, No. 10846. [Class 74 (ii)] The machine is stopped or the last-knitted loops formed on the needles are prevented from being cast off by means controlled by sinkers or sinker-like members. The invention is described in connection with a straight-bar machine and the stop motion is rendered operative by failure of the thread supply, thread slackness or mispositioning of a newly supplied thread at the needles prior to stitch formation. At intervals along the machine, members 112 are substituted for the dividing sinkers 12 and are resiliently held against the newly supplied thread. In the event of thread failure &c., a member 112 is urged by its spring to a position in which it engages above a bar 27, which bar is pivoted upon the slur cock 23. Upon further movement of the slur cock,.the projected member engages an inclined portion 29 of the bar and the bar is depressed. Movement of the bar results in a spring pawl (not shown) being disengaged from a catch on a drum 40, which is spring controlled and has a wire cable 41 connected to it. The cable 41 is also connected to a lever 44 pivoted upon a stud 45 on the usual lever 46 which is rocked by a cam on the main cam shaft 48 to produce the pressing movement of the needles. The lever 44 has at its forward end a stud 54 to engage under the forward end of the usual hand lever 52, and when the lever 52 is raised to the position shown in chain-dotted lines the needle bar 49 is moved by a spring 55 to non-pressing position. Means are provided for nullifying the action of any member 112 that may, by the operation of fashioning, become located outside the selvedge edges of the blank being knitted. The members 112 may, alternatively, be made to complete an electric circuit to energize a solenoid for releasing the pawl from the catch on the drum 40.

Title: Hydraulic control device
IPC: F16K31/524
Filed: 1943-07-12
Abstract: 589,957. Valves. ADEL 'PRECISION PRODUCTS CORPORATION. July 12, 1943, No. 11271. Convention date, Aug. 1, 1942. [Class 135] A hydraulic valve is formed with a main bore for liquid control valves and a bore intersecting the main bore and housing a cam-shaft for operating, through push-rods, the control valves. As shown in Figs. 1 and 2, the valve body 1 is provided with an inlet port 4, ports 5, 6 connected to a hydraulic cylinder, an outlet port 10, a main bore 2 and a bore 3 receiving a cam-shaft 30. The main bore 2 receives a member 11 in which are bores having seats at the top for poppet valves 24, 25, adapted to be opened by cams 28, 29 through the medium of push-rods 26, 27. The push-rods, when raised, close ports 7, 8 leading through a passage 9 to the outlet port 10, and the lower ends of passages 32 in the poppet valve stems. The cams 28, 29 are so arranged that only one poppet valve can be open at a time to allow liquid to pass from the port 4 to a port 5 or 6, return flow from the supplied end of the hydraulic cylinder being prevented by the push-rod which has opened that poppet valve, while the other push -rod allows escape of liquid from the other end of the cylinder. The member 11 may be turned to a limited extent in either direction by set-screws 36, 37 to vary the position of the push-rods relative to the cams. In one extreme position of adjustment, the push-rods close the ports 7, 8 so that the, piston of the hydraulic cylinder is locked in position and a minimum movement of the cam-shaft is required to operate the poppet valves, and in the other extreme position both these ports are fully open so that the piston is freely movable and a maximum movement of the cam-shaft is then required. Specification 570,112 is referred to.

Abstract: 717,358. Grab arm attachments for fork lift trucks. RANSOMES SIMS & JEFFERIES, Ltd. May 5, 1953, [May 5, 1952.] No. 11318/52. Class 78 (3). In a fork truck 1 the tines (not shown) or side grab arms 8, 9 are movable laterally either simultaneously or independently by hydraulic thrustors. As shown in Fig. 1, grab arms 8, 9 are slidably mounted on the lifting carriage 5 and are actuated by hydraulic rams A, B which, as shown in Fig. 4 are connected in circuit with a manually operated control valve 12 and a pedal operated selector valve 15. The valve 12 is provided with a rotary plug 30 which, in the position shown, admits fluid from the inlet pipe 38, via valve 15, to the inner ends of ram cylinders 6, 7 and allows the outer ends of the cylinders to exhaust to the reservoir through pipe 40, whilst when the plug is rotated through go degrees, the pipe 38 is put into direct communication with the outer ends of the cylinders and the inner-ends of the cylinders exhaust to the reservoir through the valve 15 and pipe 40. When the valve 15 is unoperated it is spring urged into the neutral position shown in which movement of plug 30 extends and retracts the rams simultaneously, but when pedal 18 is depressed port 48 is closed and the effective aperture of port 47 is increased so that, with plug 30 in the position shown no fluid is admitted to cylinder 6 whilst an increased flow is admitted to the inner end of cylinder 7 which thereby produces an amplified movement of arm 9 only. With pedal 18 depressed and the plug 30 rotated through go degrees pressure is applied to the outer ends of both cylinders, but as the return flow from the inner end of cylinder 6 is blocked at port 48 ram A and, thus arm g, is retracted at an increased speed. With pedal ig depressed similar independent movement of ram B and arm 8 is obtained. In a modification valve 15 may be operated manually, electromagnetically or hydraulically.
