Title: Improvements in or relating to hydraulic servo-apparatus for controlling the temperature of a fluid stream
IPC: G05D23/185
Filed: 1958-10-29
Abstract: 864,469. Fluid-pressure servomotor control systems; valves. LEDUC, R. Oct. 29, 1958 [Oct. 29, 1957], No. 34654/58. Class 135. A servo-system so proportions the fluid flow in two pipe-lines that the resulting temperature of the fluid in the single pipe-line connected to said pipes is maintained substantially constant. In the first example, Fig. 1, the pipe lines 1, 2 carry hot and cold liquid past interconnected valves 30, 31 to a pipe 3 in which a bimetallic temperature detector 20 is located. The detector 20 positions the spring-loaded stem 45 of a pilot valve 11 which controls a differential area double-acting piston 9. The servo motive fluid is taken from the pipe 2 by pipe 5. A fluidpressure integral feed-back loop 32, 33, 43, 44 is connected across the orifice 25 in the line 36 interconnecting the pilot valve 11 and the cylinder 37 of the double-acting piston which is connected directly to the valves 30, 31. The floating piston and cylinder arrangement 32, 52 introduces a derivative effect. In a modification, Fig. 2, the detecting element is a capsule 20 in the pipe 3 and controls a relay valve 18-19 which determines the fluid pressures acting on a diaphragm 50 directly connected to the stem 45a of the pilot valve 11. The feed-back loop comprises a leaky piston 25x connected to the double-acting piston 9 and movable in a cylinder the ends of which are connected to capacity chambers separated by movable piston 32 and also to opposite sides of the diaphragm 44. In a modification, Fig. 5 (not shown), the cylinder of the leaky piston is connected to the doubleacting piston and the leaky piston is connected to a feed-back spring acting on the pilot valve. In another modification, Fig. 6 (not shown), the double acting piston is not of the differential area type and does not receive the motive fluid directly from the pipe 2 but via the pilot valve 11. In another embodiment, Fig. 3, the detecting element 20, the pilot valve 11, the double-acting piston 9, the relay valve, the feed-back means and the valves 30, 31 are all in a single unit. Additional lands 23, 24 on the pilot valve provide the relay valve and the integral feed-back means. Cocks 55, 73 in the pipe 3 and pilot valve exhaust pipe 21 respectively, are operated by a manually-operable cam and can follower unit 79, 81, 83, 85 so that 73 opens first and closes last. In a similar embodiment the unit of Fig. 3 is used in a reverse way, the flow being from the pipe 3 to the pipes 1 and 2, one of which is in a cooling circuit, the two flows being then re-combined to form the controlled stream.

The heat exchanger fluids may flow in co-current or as shown in counter-current. In the heat exchanger shown fin-free zones 26, 27 are provided at both ends of the inner tube to enable the fluid to be heated to flow circumferentially before entering and after leaving the finned section of the annular space.

Title: Improvements in or relating to piston and cylinder assemblies
IPC: F16J1/09

Abstract: 665,740. Pistons. OLAER MARINE. Dec. 30, 1947 [Sept. 28, 1946], No. 34805/47. Class 122(i). [Also in Groups XXVIII and XXIX] In a piston and cylinder assembly the piston is formed with an extended portion operating in the same cylinder and having a diameter slightly less than that of the piston so as to have a loose fit in the cylinder and the extended portion is formed with an annular groove adjacent the working face of the piston and communicating with the cylinder at that side of the piston remote from the extended portion whereby any fluid leaking around the extended portion into the annular groove is prevented from leaking between the piston and the inner cylinder wall when the piston is at rest. High hydraulic or pneumatic pressures may be employed. Fig. 2 shows a fluid pressure jack in which a reduced portion 3 is separated from a main portion 21, of a piston 1, by a groove 5. The groove is connected with the exhaust side of the piston by diametrically opposite channels 4, one only of which is shown. It is stated that the arrangement prevents the piston sticking to the cylinder wall due to destruction of an oil film between the piston and cylinder by radial forces occurring with operation at high pressure. Fig. 7 shows a control valve having pistons 12 with reduced portions 3 and' grooves 5 the grooves being connected to an axial passage 14 by radial passages 13. The valve is connected to exhaust at 16. Fig. 5 (not shown) comprises an arrangement in which, a piston, similar to that of Fig. 2, is used as a balancing piston for a manually operated spring loaded ball valve. The pistons can be of circular, ellipitical, rectangular, hexagonal or other cross-section.

Classes 83 (2) and 83 (4). In a machine for making vehicle door panels by clinching the margins and welding, the assembled sheet metal panels 11, 12, Fig. 1, are arranged on a frame 13 surrounded by clinching units 29 and can be raised to a position at which the margins are engaged by a plurality of electric resistance welders 39 attached to the machine. The frame 13 is supported by a platform 19 surrounded by a movable platform 20 which is raised by hydraulic cylinders 21 to operate the clinching units 29 through individually adjustable ball jointed links 23. A hold-down pad 15 actuated by a pneumatic cylinder 17 retains the panels 11, 12 in position. The straight portions of the margins are engaged by steel blocks 32 attached to two or more units 29 while the curved flanges are engaged by short curved blocks 33, Fig. 3, each operated by separate links 23. After completion of the clinching operation the platform 19 is raised by hydraulic rams 34 while the cylinder 17 is vented through a relief valve (not shown) so that a light pressure is maintained on the panels. The flanges are then engaged by the welders 39 under the action of hydraulic cylinders 40 and the panels are finally ejected by a pad 41. In modifications the clinching may be performed by tools 54, Fig. 5, which are moved longitudinally through guides 50 by hydraulic cylinders 52 (not shown). Alternatively clinching dies 73, Fig. 8, may be supported on parallel links 71, 72 and actuated from hydraulic cylinders through pistons 74.

Title: Improved method of and apparatus for sealing electron tubes
IPC: H01J5/24

Abstract: 638,985. Sealing electron tubes. FABRICA ITALIANA VALVOLE RADIO ELETTRICHE. Nov. 28, 1946, No. 35353. Convention date, June 13, 1945. [Class 39 (ii)] [Also in Groups XXIII and XL (a)] Electron tubes are sealed and, while on the same sealing head, are then annealed by being maintained for a given time within a metal jacket the internal temperature of which is regulated from the outside. As shown a stainless steel tubular shaft 7 rotatably mounted in a sleeve 2 in the table 1 carries a pulley 14 and has longitudinal slots 17, 18. A tubular shaft 8 located in shaft 7 rests on an apertured support 10 at the bottom, communicates with the tube 12, and carries fixed arms 15, 16 which pass through the slots 17, 18, so that the tubes rotate together but may have relative axial movement. The arm 15 bears a vertical rod 19 with two collars 20 at the top, while arm 16 has a socket 21 with a rotatable rod 23, and a ring 25 with a hooked portion 27 which engages between the collars 20, being urged by spring 33 connecting arms 30, 31 on the rods 19, 23. A second arm 32 on the rod 23 may be operated by a track 44 to open the frame. A thin steel cylinder 28 closed at the top is fitted into the ring 25. A stud 35 fitting into the top of the shaft 7 has a cup 36 which supports the cap 37 and fittings 39 over which the electron tube 40 is supported, the suction tube 38 from the cap passing into shaft 8. The tube 40 and cylinder 38 are rotated and separately heated, and when the tube is sealed its heating is discontinued, the support 10 is lowered so that the cylinder 28 at controlled temperature surrounds and anneals the tube. The invention may be hand operated on simple machines, or fitted to an automatic rotary apparatus, and may be arranged so that the cylinder 28 is stationary and the tube 40 raised into it. Fig. 6 shows an application where the exhaust tube 38 is integral with the tube 40, the latter being lowered into the cylinder 28.
