Title: Improvements relating to shaper mechanism for winding yarn on weft bobbins in spinning mules
IPC: D01H3/12
Filed: 1928-12-07
Abstract: 323,103. Firth, F. C., Senior, S. J., and Tattersfield, C. T. Dec. 7, 1928. Mules.-To produce a relatively short traverse at the base of the cop during the winding of a predetermined number of draws, whereby, during weaving, this will become exposed to view as the cop approaches exhaustion, the shaper rail 1, Fig. 2, is provided with an auxiliary rail 4, which is raised about the rail 1 at the commencement of the winding, and is lowered automatically to be out of action where the desired number of draws have been made. The auxiliary rail 4 is pivoted to the main rail and provided with hanging pivoted arms 8, 9 engaging stops 12, 13 when vertical. The rod 14 connecting the shaper-shoes 3 carries a bracket 15 with an incline 16 adapted to raise the arm 9 and lift the rail 4 until the arm 8 swings into a vertical position to support it. The knocking-off mechanism to engage the arm 8 and release the rail 4 comprises a rod 17 controlled by a spring 32 and a spring lever 19 carrying a stud 22 engaging a slot in the rod. The rod 17 slides in brackets 18 and is provided with teeth 20 engaged by ratchets 23, 24. The ratchet 23 is pivoted on a lever 26 arid the ratchet 24 on an extension of a bracket 18. The lever 26 normally rests against an adjustable stop 41 under the action of a spring 56. At each traverse of the carriage 45 an arm 44 engages an adjustable screw 43 on the lever 26 and moves the rod 17 forward one tooth. When the desired number of draws have been made the rod 17 is moved into such a position that the end of the slot engages the stud 22 to move the lever 19 and release the prop 8, allowing the auxiliary rail to fall. A stop 46 on the bar 17, at this stage engages the lever 26 and holds it over in such a position that during the remainder of the winding it is not engaged by the carriage. At the commencement of a fresh set stops on the rod 14 engage the ratchets and lift them to release the rod 17 and allow the spring 32 to draw it back. A pin placed in the appropriate hole 57 engages the bracket 18 to act as a stop. In place of the auxiliary rail, the main rail may be similarly raised and supported at the desired angle.

Title: Electromagnetic flexible tube restricting devices
IPC: H01F7/08
Filed: 1975-08-15
Abstract: 1514925 Valves PLESSEY CO Ltd 15 Aug 1975 [16 Aug 1974] 36121/74 Heading F2V [Also in Division H1] An electromagnetic actuator for controlling fluid flow by restricting the cross-section of a flexible tube 26 comprises a winding 1 on a cylindrical iron core 2 of a magnetic yoke structure, secured by an iron L member 4 press fitted at 3 to the core and hinged at 5 to an armature 6 by an, e.g. beryllium copper strip clamped to the yoke and armature. Movement of the latter is controlled dependently on the energizing current by a rectangular member 13 carrying a disc shaped iron polepiece 14 moving into a circular opening of armature 6, when the latter upwardly pivots towards the winding against adjustable biasing spring 16 held between bracket 17 of core 2 and bracket 18 of armature 6. The movement of the latter varies the flux pattern in the airgap between polepiece 14 and the wall of opening 15 until equilibrium is attained between magnetic force and spring bias, so that the armature position is selectively controllable by the energizing current. The ratio between exerted force and energizing current diminishes as the polepiece moves into the opening. On de-energization the armature is rapidly released to its inoperative position. A restrictor member 20 dependent from the armature pivots on pin 21, and plate 23 secured to the. yoke and polepiece is hinged to platform 24 carrying the flexible tube 26 in trough 25 engageable with tapered end 27 of restrictor 20 for control of the fluid flow, with cut-off on de-energization. Different sizes of tube are interchangeable. The characteristics are variable by suitably shaping the periphery of polepiece 14. The device may provide incremental movements of an actuating member.

Title: Apparatus and process for continuously producing a sheet shaped product
IPC: B29C48/08
Filed: 1974-01-07
Abstract: 1431732 Continuous sheet casting MITSUBISHI RAYON CO Ltd 7 Jan 1974 [18 Jan 1973 (2)] 36190/75 Divided out of 1431731 Heading B5A In a double belt machine for the continuous sheet casting of polymerizable liquids in which sealing gaskets 7 are continuously drawn from storage 31 and fed between the working runs of the belts 1 at each side thereof and at the same running speed, the sealing gaskets 7 are passed through a heater 61, Fig. 6, prior to entering the belts to remove residual strain resulting from deformation during storage. A gasket 7 from a roll 31 passes between a driven roll 39 and an adjustable pinch roll 37, and around a roll 51 mounted on a carrier 49 displaceable along rails 47 in response to changes in tension in the gasket. Movement of the carrier 49 rotates by means of a rack-and-pinion, not shown, a rotor 57 in a detection device 59 which controls the speed of the motor M of the drive roll 39 to maintain constant tension and therefore the same speed as the belts. A metering pump 5 supplies incompletely cured methyl methacrylate polymer and catalyst dissolved in the monomer to a feeding device 6 mounted for transverse sliding movement on T-shaped rails of a carrier 20. The carrier 20 runs on rails 29 and is prevented from contacting the belt 1 by stops 24 which would engage the ends of arms 30 if the pins 25 which connect the arms to the carrier were removed. The other ends of the arms 30 are journalled to the shaft of a belt pulley 2. The tension in the belts is adjustable by displacement of the pulleys 2 by hydraulic or pneumatic cylinders 15 or by springs, not shown, the carrier 20 moving with the pulley 2 and maintaining the correct position of the feeding device 6. Rollers 4 maintain the spacing of the belt 1 while hot water is sprayed at 8 on to the back of the belts to heat the resin. The belts then pass through infra-red heaters 9 or a hot air oven to complete the resin cure and through cooling zones 10 and 11. Reference has been directed by the Comptroller to Specification 1,300,400.

Title: Process for the production of heavy water
IPC: C01B5/02
Filed: 1958-11-12
Abstract: In the production of water enriched in heavy water, the reaction water obtained in the catalytic hydrogenation of carbon monoxide and/or carbon dioxide, is used as the supply to a heavy water enrichment process, since it is found that this reaction water is already enriched in D.  Processes for heavy water enrichment are distillation, electrolysis, electrolysis combined with steam/H2 exchange, or dual temperature exchange, e.g. water/water, steam/H2 and water/H2S. O2-containing organic compounds should be removed before the process.  The catalytic hydrogenation may be carried out at atmospheric, or elevated, pressures, e.g. 8-30 Kg/sq. cm., and the catalyst may be a group 8 metal, e.g. Fe, Co, or Ni, which may be in the form of a skeleton, or prepared by precipitation, sintering, or fusion, and may be used as a fixed, fluidized, or moving bed, or as a slurry or suspension in a liquid.  The methanation of town gas is a suitable catalytic hydrogenation reaction.  Specification 679,785 is referred to.
