Title: Improvements in or relating to keyboard telegraph transmitters
IPC: H04L17/06
Filed: 1924-11-05
Abstract: 246,919. Hilton, C. F. Nov. 5, 1924. Keyboard transmitters; type-printing telegraphs. -The operation of each key effects the movement of a corresponding combination of rods, each rod so moved closing a switch to connect a corresponding contact to a source of current, whereupon a wiper engages the contacts in turn to connect them to line, the operative connection between each key and the rods comprising a member which is connected to the key and effects the movement of another member acting directly on the rods. Depression of a key L, Fig. 2, imparts a sliding movement against the action of a spring Q to a corresponding bar M carrying three projections O. One projection O operates a lever P engaging a tooth 8, Fig. 4, of a corresponding disc K rotatable on a sleeve H, Fig. 1, mounted on a central shaft A, and as the disc rotates corrugations 4 on it engage recesses 7, Fig. 3, in a plate J, to impart a sliding movement without rotation to the plate against spring action, thus engaging projections 9 on the plate with shoulders Z<1> on a combination of rods Z corresponding to the depressed key. The resulting movement of these rods closes contacts at 5, 6 to connect corresponding contacts 3 to + or - battery and removes detent G from the path of the wiper arm 2. The second projection O acts through linkwork, Fig. 2, to operate racks C and S carried by shaft T. The rack C engages a toothed wheel B mounted for rotation in one direction only on the shaft A. thus winding a spring D of which one end is fast to the shaft A and the other end to a drum E which is engaged by a brake band F and carries the arm 2. The rack S similarly winds a spring X for substantially rotating the sleeve H. The drum E is held by the band F until the third projection 0 acts on the brake lever F<1> to release the band, whereupon the arm 2 connects the energized contacts successively to line. Upon release of the key the bar M is returned by its spring Q, the arms 9 disengage the shoulders Z<1>, and the spring X rotates the sleeve H to bring the plates J into correct position in relation to the arm 2. In order to lock all other keys when one key is depressed a projection on the actuated bar M operates a centrally pivoted comb R, Fig. 2, to engage the teeth of the comb with the projections on the other bars M.

Abstract: 710,856. Joining rods. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Oct. 29, 1951 [Oct. 30, 1950], No. 26466/50. Class 99 (1). [Also in Groups VIII, IX and XXV] An apparatus for butt welding together two pieces of thermoplastic rod comprises a pair of clamps for gripping the pieces, at least one of the clamps being movable endwise to and from the other clamp towards which it is resiliently urged, releasable means for holding the clamps apart, and a heating blade which can be moved into an operative position between the clamps to heat the neighbouring ends of the rods projecting from the ends of the clamps and can be withdrawn to allow the clamps, after release of the holding means, to move towards one another under the influence of the loading force to press the hot ends of the pieces together. The apparatus comprises a framework, 1, 2, 3 to which one clamp 6 is attached by screws 7. A pair of rods 20 is held between the clamp 6 and a bridge piece 18 and a second clamp 22 is slidable thereon and urged towards the first clamp 6 by a pair of springs 28, the force in which can be adjusted by varying the position of collars 29. Each clamp comprises a pair of jaws 9, 10 located in position by dowels and held together by pivoted spring clips 16. The jaws 9 and 10 are provided with corresponding grooves 13 and 14 with which to grip the pieces of rod to be joined. A cylindrical extension 24 upon the clamp 22 is located within a corresponding aperture 27 in the clamp 6 when the clamps are closed together. A bridge piece 31 is slidable upon a pair of struts 32 and carries a rod 30, the upper end of which is wedge-shaped. A pivoted lever 35 co-operates with the bridge piece 31 so that by depressing a handle 40 the bridge piece is raised and the wedge-shaped portion of the rod 30 cooperates with a chamfer 34 on the clamp 22 to separate, and hold apart, the clamps as shown in Fig. 4. The lever 35 is returned to its original position by a spring 41 and the rod 30 held by the pressure between the clamps 6 and 22. The rod 30 is recessed at 46 and 47 to provide a setting up guide for the pieces of rod. An arm 43 is pivoted to the frame 1 and comprises a heating blade 44 and a projection 45. The blade 44 may be heated by a gas flame or electrical means, and when the arm is rotated to the position shown in broken lines, Fig. 2, between the separated clamps, the projection 45 holds the clamps apart and being slightly thicker than the rod 30, allows the latter to fall to its lower position, and the blade 44 heats the ends of the rods. When the arm 43 is again raised, the clamps are urged into contact by the springs 28 and the softened ends of the rods become welded together.

Filed: 1973-06-04
Abstract: 1387361 Drainage systems KENDALL CO 4 June 1973 [6 June 1972] 26566/73 Heading A5R A closed system for draining liquid from a body cavity comprises a catheter 12 with a drainage eye 18 near its distal end and a drainage lumen 22 extending from the eye 18 to the proximal end 24 of the catheter, a drainage receptacle 16 for collecting the liquid, a drainage tube 14 having a pair of lumens 32, 34, in communication adjacent each end of the tube 14, the lumens communicating with the draining lumen 22 of the catheter 12 adjacent the proximal end of the catheter and with a drip-chamber 48 leading to the drainage receptacle 16. One lumen 32 of tube 14 has a one-way valve 52 at the end adjacent the catheter to permit the passage of air from lumen 32 to lumen 34 and to prevent the passage of liquid from lumen 34 into lumen 32. The one-way valve may be a flap-valve. In a modification (Fig. 2, not shown), the lumen 34 at the distal end of the drainage tube is extended beyond the lumen 32 and communicates with the latter through radial apertures covered by a filter which permits air to pass from the lumen 32 into the lumen 34, and thus to the catheter, but prevents the contrary passage of liquid. By these means fluid draining from the cavity through lumen 34 will be replaced with air from the receptacle 16 via lumen 32, thus maintaining a positive pressure in the cavity circulating sterile air. The catheter may include a balloon 26 inflatable through an inflation lumen 30 and a valve in a member 28.

Title: Improvements in and relating to hot beds for rolling mills
IPC: B21B43/02
Filed: 1931-09-25
Abstract: 377,015. Rolling. JENSEN, C. A., 77, Chancery Lane, London.-(Birdsboro Steel Foundry & Machine Co. ; Birdsboro, Pennsylvania, U.S.A.) Sept. 25, 1931, No. 26772. [Class 83 (iv).] Roller tables.-The reciprocating conveyer bars of a hot-bed are formed with two different work-supporting surfaces (notched or smooth) either of which may be turned uppermost to engage the work. The work bars discharged from a rolling mill are conveyed by a series of rollers 2 (driven by separate electric motors 3) between which are a series of plates 4, Fig. 3. The plates 4 are reciprocated up and down by eccentrics 14 acting through push-rods 11 with spring cushioning 25<1> coupled to the pivoted arms 7, so that the bars are lifted off the rollers 4. The bars are then kicked off sideways by eccentric-operated levers 40 extending up between plates 4, the bars thereby being pushed on to the slopes 43 and rest against shoulders 44. The bars are then lifted by plungers 45 to the slope 46 and are stopped by other plungers 48 until these are lowered when fingers 64 feed them to the preliminary cooling bed 49. The lift plungers 45, 48 are operated from a rocking shaft 54. To pile the work on the bed 49 for pack annealing if desired the stops 65 with their ropes, pulleys, and counterweights 68 are retained upright to collect the bars, and the shaft 63 stops the feed by-pushbars 60 after their fingers 64 have transferred each bar to the bed 49. The fingers 64 are moved along the bed by rack and pinion 62. The pile of bars against the stops 65 increase by each bar pushing the stops 65 along against the pull of their counterweights 68 until the stops 65 reach the slope 71 whereupon they tilt down and deposit the work on the main cooling bed 156. The sets of conveyer bars 80, 81 comprising the main cooling bed are supported on sills 82 &c. reciprocated alternately in an oval &c. path, the vertical component being got by shafts 97 rocked by a rod 106 reciprocated from a main rock shaft 115, the horizontal component from a rod 130 rocking the shaft 133 and thereby reciprocating cross shafts 140 coupled to the sills. The amount of these reciprocations is adjustable. The V-shaped conveyer bars 80 are pivoted on pedestals 157, Fig. 11a, so that to bring one or other of their surfaces uppermost an electric motor 162 (not shown) with cut-off limit switch is started to move rods 174 coupled to links 180 which turn the V-bars round. Specification 377,151 is referred to.
