Title: Pushbotton tuner
Inventor: STAMM RUSSELL DOUGLAS
IPC: H03J5/12
Filed: 1968-09-04
Abstract: 1,207,014. Releasable fastenings. GENERAL INSTRUMENT CORP. 4 Sept., 1968 [24 Nov., 1967], No. 42140/68. Heading E2A. [Also in Division H3] The specification describes a locking means 86 (Figs. 4 and 5) for a tuning frequency setting-plate 80 and an anti-jam plate 140 (Figs. 4, 5, 8 and 10 and Figs. 1 and 2, not shown), for preventing wrong selection of pushbuttons 94 and a lever 108 of a push button tuner (see Division M3Q). When button key 48 is pressed cam 80 is moved to the angular position set by tuning crank 42 and on further pressing the button key 48 part 90 (Fig. 5) engages lock lever 86 to lock the tuning frequency cam 80 in position. The cam 80 is only released by pulling the button key. The lockable cams 80 are secured to side keys 66, 68 which are selectively operated one at a time by the button key 48. This is achieved by shuttles 100 which are moved transversely by a shuttle plate 104 operated by a lever 108. An anti-jam plate 140 is secured to the shuttle plate 104 and has pairs of slots 150, 152 (Figs. 8 and 10) for each button 94 to prevent wrong selection. With the lever 108 and shuttle 100 in the left position (Fig. 8) when the button 94 is pulled forward the lever 108 and shuttle 100 is prevented from movement to the right. Similarly when the lever 108 and shuttle 100 are in the right position with the button key 48 pulled out (Fig. 9, not shown), no movement of the lever 108 or shuttle is permitted. If the lever 108 is wrongly positioned in the center (Fig. 10) then edges 148, 146 and 142 prevent the side keys 66, 68 and button key 48 from outward movement.

Abstract: 1276863 Welding by pressure; chucks CATERPILLAR TRACTOR CO 25 Aug 1969 [30 Sept 1968] 42288/69 Headings B3B and B3R A collet chuck assembly 12 for a tubular workpiece comprises a chuck body 31, an outer contractible collet chuck 36 mounted within the chuck body, an inner expandable collet chuck 37 concentric with the outer chuck and means for clamping the chucks upon the tubular workpiece, the clamping means being such that the initial clamping force on the workpiece is exerted primarily by the inner chuck and the clamping means including an actuator stock coupled with the outer chuck and such that when one end of the workpiece abuts a member in contact with the actuator block, axial pressure on the workpiece further contracts the outer chuck. A chuck assembly for the rotatable shaft of an inertia friction welding machine comprises a chuck body 31 screwed and keyed by key 34 to a plate 33 mounted on the shaft, a split collet 36 secured to the actuator block 40 inside the body 31, the collet 36 having a tapered portion 38 mating with a tapered surface 39 on the body 31, and a split collet 37 having a tapered surface 43 associated with a tapered mandrel 44. The mandrel 44 is secured to a bolt 46 screwed in a shaft 48 secured to the rod 51 of an hydraulic clamping cylinder and the collet 37 is secured to a plate 52 keyed by key 53 to the block 40. A seal ring 58 compressed between the block 40 and a plate 57 frictionally grips the shaft 48. In operation a tubular workpiece WPI is inserted between the collets 36, 37, the rod 51 is retracted against the spring 59 to cause the mandrel 44 to expand the collet 37 and axial force on the collet 37 is applied to the block 40 which draws the outer collet 36 into the chuck body 31 to contract the collet 36 to secure the workpiece. After the friction welding of the workpiece to another workpiece the rod 51 is moved to the right to release the collet 37 and by contacting a block 56 in contact with the block 40 urges the collet 36 to the right to release the workpiece. In modification for use with a smaller diameter tube the outer collet extends further radially inwards and the mandrel 44 and inner collet 37 are replaced by a mandrel secured to the actuator block and a head operable by a shaft secured to the hydraulic clamping cylinder to act on a split collet engaged on a tapered surface of the mandrel. It is stated that the inner collet may be removed so that the outer collet may act on a solid workpiece.

Title: Improvements in or relating to gas separation with particular reference to air separation
IPC: F25J3/04
Filed: 1963-10-29
Abstract: 1,006,499. Cold separation of air. R. STOKLOSINKI. Oct. 29, 1963, No. 42638/63. Heading F4P. The temperature gradient between the lower and upper ends of an air separation column 10 yielding product oxygen is maintained by withdrawing nitrogen from the head of the column through lines 24, 32, 38, compressing in a multi-stage compressor 42, and passing portions at differing pressures and temperatures through a plurality of vertically spaced reboilers 20 arranged in parallel within the column and in which the nitrogen is condensed. In operation, air having been compressed at 61, cooled in exchangers 66, 68, dried at 72 and further cooled in exchangers 34, 26 traversed by counterflowing effluent nitrogen, is fed at 12 into the upper portion of column 10 and effluent nitrogen leaving the warm end of exchanger 34 through a line 38 enters the first of seven stages of compressor 42. Small portions of nitrogen are withdrawn from the subsequent stages through lines 44 ... 49 and after being cooled in exchanger 34 are fed to the reboilers 20 and the so liquefied nitrogen portions are then separately expanded at valves 50 into a line 52 and in part fed through a line 18 direct to column 10 and in part through a condenser 16, line 58 and exchanger 34 to the inlet of the second stage of the compressor 42. That portion of nitrogen leaving the last stage of the compressor not being passed to the bottom reboiler 20 is expanded at 59 and returned through exchanger 34 to the inlet of the first stage. Liquid oxygen in a line 22 is freed of residual carbon dioxide and hydrocarbons by nitrogen regenerated absorbers 78 and is then passed through a line 84, exchanger 34 and a product gas line 86.

Title: Plugs
IPC: G21C3/10
Filed: 1972-09-15
Abstract: 1404234 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 7 Sept 1973 [15 Sept 1972] 42838/72 Heading G6C A nuclear fuel can is provided with a closure plug 15 having a closure portion 20 dimensioned to engage the open end of the can, to which it is seal welded at 21, a stem 19 of reduced diameter extending axially from the closure portion 20 into the can interior, and a flange 18 of increased diameter at the end of the stem 19 and formed of a material which is selectively susceptible of attack by hydrogen. The closure portion 20, stem 19 and flange 18 may be machined from a single billet, preferably of Zr or a Zr-base alloy. Whether integral or not, the flange face directed towards the can interior may have a pronounced surface roughness, e.g. the machine tooling marks are preserved, so that it is rougher than the inside of the can wall to encourage preferential adsorption of H 2 . In the embodiment shown in Fig. 2, a double ended plug interconnects two fuel cans 11, 12 end-to-end and at the same time provides intercommunication between the interior spaces of the two cans. The ends of the plug are joined back to back by a bridge piece 16 formed with a pair of spaced flanges 17 which project peripherally proud of the can wall in order to space the fuel can from the wall of the channel in which it is situated, or from adjacent fuel cans. Each end of the plug is formed with a flange 18, stem 19 and closure portion 20. A hole 22 extends longitudinally of the plug. In operation, H 2  dissociating from water desorbed from the fuel pellets 13 is adsorbed by the rough surface of the flange 18 which is also its hottest region. ZrH 4  is formed which because of the temperature gradient from the flange face towards the stem 19 will diffuse along grain boundaries into the stem 19. In this cooler region, the hydride tends to precipitate at the stem surface. This action avoids migration of the hydrides from the stem 19 into the closure portion 20 and thence into the seal welds 21 which would then be weakened and become very susceptible to fracture.
