Title: Thermionic Cathode
IPC: H01J1/22
Filed: 1969-02-28
Abstract: In a thermionic cathode assembly comprising a hollow support on which is provided thermionically emissive material, the support accommodating a heater comprising a filament on which is provided a surface layer of a dark coloured material, the surface layer is separated from the filament by porous insulating material to inhibit ion conduction therein and diffusion of metal from the dark layer into it thereby allowing the cathode to be operated at up to 1200 C. with a potential difference of 500V between the filament and the support. The drawing illustrates a dispenser cathode having emissive material 2 on a support 1. A tungsten filament 4 is helically wound round a molybdenum core (subsequently removed at 5) which is bifilarly wound round a ceramic cylinder 6, and coated with two layers 7 and 8 of Al 2 O 3 BeO, or MgO deposited respectively by cataphoresis and immersion. The porous layer 9 is formed by immersion in a mixture of one of the above oxides and MoO 3 followed by sintering for 5 minutes at 1500 C. in a reducing atmosphere which converts the MoO 3 into Mo. The assembly is then immersed in a suspension of Al 2 O 3 with WO 3 , followed by heating for 2 minutes at 1600 C. in a reducing atmosphere which reduces the WO 3 to metallic tungsten forming the dark layer 10. The molybdenum core of the filament and the molybdenum in layer 9 are dissolved by etching so that the layer 9 is porous and contains 50-75% of cavities by volume. As alternatives, the porous layer may be formed between two solid insulating layers or the solid insulating layers may be omitted. The cathode may be used in a cathode-ray tube and may have a warming-up time of about 7 seconds.

Title: Method of and apparatus for winding a yarn in which the yarn tension is controlled
IPC: B65H54/52
Filed: 1969-11-28
Abstract: The tension in a yarn taken at constant speed from an open-end spinning device is controlled by gauging the yarn tension and varying the difference between the take off and winding speed accordingly. As shown, open-end spun yarn 2 is passed over tension sensing arm 4 over fixed guides 5 and 6 and traversed onto the package 8 which is driven by drum 9. The drum 9 is pivotally mounted and rests on a friction driving ring 12 which is axially movably position on drive roll 10. The speed at which the drive roll 10 drives the package drive drum 9 is determined by the axial position of friction ring 12. The position of this ring 12 is varied by the tension sensing arm 4 acting via extension 23 and fork 15. There is a minimum tension variation required before the speed of the drive drum 9 is increased as determined by the distance between extension 23 and the coacting stops 17, 18 on the fork 15. In alternative embodiments, (a) the tension sensing arm is attached directly to the fork 15 (Fig. 4) (b) the sensitivity of a plurality of winding mechanisms is varied from a central point via a rod and springs attached to the forks 15 (Fig. 5) (c) the fork 15 is moved in either sense (so as to move the friction ring 12) by a lead screw device which can be moved to bring it into contact with one of two oppositely rotating rolls (Figs. 6 and 7) (d) when the yarn breaks the extreme movement of the fork can be terminated by a lifting device (Figs. 7 and 9) or a slipping clutch (e) the yarn tension is varied according to the size of the package with or without other variations being superimposed (Fig. 10) the yarn tension is maintained constant with a decreasing contact pressure of the package on the bobbin as the package grows (Fig. 11). The yarn take off speed can be varied instead of varying the winding speed.

Title: Hydraulic device with rotor seal
IPC: F04C2/10
Filed: 1975-03-21
Abstract: In an improved hydraulic device the leakage of fluid between a rotor and a first one of a pair of end plates is prevented by a metal-to-metal seal between the rotor and end plate. To maintain the seal, the rotor and end plate are urged together under the influence of high pressure fluid. In one embodiment of the invention, an annular seal formed of a ultrahigh molecular weight polyethylene is disposed on a side of the rotor opposite from the metal-to-metal seal. The annular rotor seal cooperates with a second end plate to form a cavity in which high pressure fluid is trapped to press the rotor firmly against the first end plate. In a second embodiment of the invention the seal is located on the opposite side of the first end plate from the rotor and cooperates with a fixed surface to form a cavity in which fluid under pressure is trapped. This relatively high pressure fluid presses the first end plate firmly against the rotor.

Title: Method of constructing a valve
IPC: B23P15/00
Filed: 1978-03-31
Abstract: The present invention relates to a method of constructing a valve. The valve comprises a casing with a bore therein for receiving a valve member. The bore also receives a plug which is engageable with the valve member to control communication through an opening on the plug. The method comprises the steps of inserting the valve member in the bore, connecting the plug with the casing such that the valve member is engageable with the plug and welding the plug to the casing while at the same time embedding the valve member into the plug to provide a valve seat on the plug.
