Title: Improvements in and relating to platen presses for paper board
Inventor: SHAW JOSHUA RODNEY
IPC: D21J3/00
Filed: 1952-05-23
Abstract: 720,414. Platen presses for paper-board. SHAW & SONS (SALFORD), Ltd., J. May 15, 1953 [May 23, 1952], No. 13066/52. Class 96. A press, for hard paper-boards, which may be an assembly of e.g. 4 units, has one or both platens of each unit formed as a screen, as by wedge-section wires 37, Fig. 4, wound about bolts 40 secured to clamping-bars 34, thus forming suction openings 42 communicating with grooves 32, openings 36 and suction conduits 33. The openings 42 extend in the direction in which the boards are passed through the press, e.g. by an endless felt 50, Fig. 1, the upper and lower runs of which pass above and below a floating platen 21, and all the end rollers, &c., 45, 48, &c., of which rise and fall with a crosshead 19. The felt 50 may have a metal indicator 55 passing magnetic switches to ensure that the seam or join in the felt always comes to rest outside the press. There may be an upper press felt 53, its slack being taken up by springs 54 when the press closes. Boards may be pressed above and below the floating platen 21 and may be released, after pressing, by compressed air. Modifications comprise different forms of edge-seals.

Patent GB-133114-A (GB)
IPC: B01D53/50
Abstract: 133,114. Palin, J. Aug. 2, 1918. Systems for controlling reciprocating motion. - An electric motor for a hoist or the like is controlled by switches operated automatically to run for a certain time in a forward direction, to run for a certain time in the reverse direction, and then after a predetermined lapse of time to run again in the forward direction. Two switches A, B are supported by a platform a fixed to vertical tubular pillars C, D which are connected by a cross-tube G. One end of the operating-lever c<1> of the switch A is forked and connected by a pin e to a plunger g in the tube C, and the other end of the lever is connected by a rod h to a ring i which can slide on the tube D. The other switch B is operated by an arm connected by a rod to a ring r on the tube D and to a plunger o in the tube D. Two endless chains s, t driven by the controlled motor are arranged on opposite sides of the pillar D and are connected by slotted links x and pins y to a tubular block y<1> whicH, in its lower position, surrounds the plunger o. An opening at the top of the tube D is connected to an inlet on the tube C by a passage with a number of baffle-plates to delay the passage of the operating-weight. When the apparatus is idle, the ball weight is held by a stop near the top of pillar C, and the pins y and slotted links x of the chains are near the top of the pillar D. When the stop is withdrawn, the ball falls upon the plunger g to close the switch A to start the motor. This operates the chains s, t until the pins y reach the lower end of the pillar D and depress the ring i, thereby opening the switch A. This movement of the switch lifts the ball until it reaches the cross-passage G, when it rolls into the pillar D and falls upon the plunger o, which then closes the switch B through the pin n and rod m. The motor is thereby reversed, and the chains s, t are moved until the pins y strike the upper ring r and open the switch B to stop the motor. The movement of the chains raises the ball weight to the outlet of the pillar D, and it rolls through the baffle passage to the inlet of the pillar C, and the cycle of events is repeated.

Abstract: 119,496. Stierlin, E. 'Weber-. Sept. 26, 1917. Fastenings; springs. - Female press-button parts are made from strip, stamped b 1 a n k s being punched out and carried by a rotary table past tools which cup them, form and insert the springs, turn over the edge to secure the springs and finally eject the finished buttons. The strip is fed from a drum 4 and beneath presses 2, which gradually form depressions therein, by adjustable pins 20 carried by a bar 7 which has a rectangular movement, the vertical component being effected by cams 13 acting through levers 10, Fig. 4, and pistons 9 carrying bowls 8 and the horizontal component by a cam 17 and spring 14. The depressions are slitted by saws 20, 21 and the strip is cleaned by brushes 25. A blank is then cut by a punch 26 coacting with one of a series.of dies 35, Fig. 2, carried by a table 33 which is intermittently rotated by a cam 36. Each die 35 has a cutting edge 44, Fig. 8, in a ring 43 capable of limited vertical movement in the block 39, which is capable of lateral movement on the table and is alined, at each operation, by pins, carried by the tools, engaging holes 55, Fig. 9, therein. The blank is then cupped by a die 65, Fig. 2, which forces down a piston 45 and this is raised, on the return of the die, by a spring and lifts with it the ring 43, Fig. 8, by the friction spring 48. Springs are inserted in the button at 66 and the edge turned over by a press 70 which also presses down the ring 43. The pin 49, Fig. 8, which serves to aline the strip and blank, is then raised by a pin engaging a fixed incline and the finished button is removed by means not shown. Each spring is formed from a length severed by a cutter 74 from a strip a which is pressed by the semicylindrical head of the former 81, Fig. 16, into a die 84, the legs are then successively bent by formers 88, 87, the free ends passing into a hole 93, Fig. 17, during the process and being deflected downwards by the inclined edge 94 to produce springs not all in one plane as shown in Figs. 13, 14. The spring is then forced down by tongues 103 and a curved blade 110 carried by a rod 100 actuated by a tappet 102 and passes over an expander 108 into the button blank. The feed, cutter, and formers are actuated by cams on a shaft 77, Fig. 2.

Title: Improvements in or relating to polymerisation catalysts and the polymerisation of unsaturated organic compounds
IPC: C08F10/00
Filed: 1961-04-18
Abstract: A polymerization catalyst is made by reacting a lamellar complex comprising an alkali metal and carbon, with an organic activator under conditions such that an alkali metal alkyl is formed, and mixing the reaction product formed, or a part thereof comprising the alkyl, with a halide other than a fluoride of a metal of Group IV(A), V(A), or VI(A), of the Mendel<\>eeff Periodic Table.  The activator may be an alkyl or aryl chloride, bromide or iodide, or a hydrocarbon such as acetylene, butadiene, isoprene, propylene, isobutene, or 2-methylpentene-2.  The catalyst is used to polymerize feedstocks of ethylene, propylene, butenes and mixtures thereof.  The feedstocks are treated to remove allene and/or methyl-acetylene, and also they are essentially free from water.  The feedstocks may contain saturated hydrocarbons and also hydrogen.  The catalyst may be employed as a fixed bed, a fluidised bed, or a slurry in a solvent. The reaction may be effected batchwise or continuously. The polymers are recovered by conventional techniques.  Specification 825,902 is referred to.
