Title: Improvements relating to sliding sashes, shutters and the like
IPC: E05D13/00
Filed: 1945-06-19
Abstract: 593,886. Sliding sashes, shutters, and the like. SHARP, A. June 19, 1945, No. 15612. Addition to 574,298. [Class 20(iii)] [Also in Group XXV] In means for controlling the movement of sliding sashes, shutters, and the like, quickpitched screw stems s are fixed in position and engaged by the nuts a mounted to rotate in boxes d connected to the arms h projecting from the sashes g, the nuts being arranged to act through one-way clutches operating frictional members so that the frictional resistance is sufficient to oppose the nut turning in one direction, but the nut is free to rotate in the other direction along the screws. In the form shown, the nut a is surrounded by the one-way clutch mechanism e, which in turn is surrounded by a ring b engaging a frictional collar c. This construction may be replaced by a friction disc bearing on a lower disc formed with ratchet teeth on its undersurface to engage the ratchet teeth formed on a nut. The weight of the sash may be counterbalanced by a spring, e.g., as shown, by a coiled spring within the drum k rotatable about the arm h, a band of steel m being coiled round the drum and secured at the top of the frame. A helical spring or a spring drum formed with a pinion engaging a rack secured to the frame may be used.

Filed: 1940-10-28
Abstract: 544,076. Filling-machines. AVERY, Ltd., W. & T., and GREENWAY, E. A. Oct. 28, 1940, No. 15770. [Class 94 (i)] [Also in Group XVIII] In a weighing and packing apparatus a sack or other holder may be lifted off the weigh beam and submitted to a jigging operation by a continuous rotating cam which may be moved into operative position at will. As shown, the sack holder 11 is connected by a flexible sleeve 12 to an upper part 11a resting on the knife-edges 13 of the weighbeam 5, the holder 11 being suspended from the upper part by links 14 and brackets 16. After the filling of a sack, the operator pulls down a handle 27 thereby causing a linkage 21 to move a forked frame 17 to the right. A roller 29 on the end of the frame engages an inclined block 30 mounted on a camcarrying arm 31 pivoted on a shaft 31a. A fixed plate 32 prevents the roller from rising and consequently the arm 31 is depressed thus bringing the continuously-rotating cam 35 'into contact with a roller 36 freely mounted on a two-armed lever 37 fulcrumed on a spindle 38. A block 37a on the lever engages the bracket 16 and lifts the sack holder 11 off the links 14, the continued rotation of the cam 35 giving a jigging or packing movement to the sack. A catch 28 is provided for retaining the handle 27 in the depressed position until jigging is completed. On release of the catch, springs 18 return the frame 17, and the sack holder 11 is again deposited on the links 14. The cam 35 is rotated by belting from a motor 44. A pointer .9 indicates the condition of balance of the weighing apparatus.

IPC: F24D3/02
Filed: 1937-06-08
Abstract: 496,957. Heating by circulation of fluids; pumps. UNGE, N. W. June 8, 1937, Nos. 15888 and 15889. Convention dates, June 19, 1936 and May 9, 1937. [Class 64 (ii)] [Also in Group XXVIII] In apparatus for circulating a liquid in a pipe system for heat transmission, cooling and the like, a radiator or other heating apparatus 4 is connected by pipe 5 to a heating vessel 1, and by pipe 3 to a superposed vessel 2 connected by pipe 6 to the vessel 1. If the vessel 1 is heated and vapour generated, or if vapour is introduced from an outside source, liquid is expelled through openings 13 into vessel 2. The vapour is condensed in contact with liquid cooler than the heated surface of the vessel 1, and liquid circulates from vessel 2 through pipe 3, heat-exchanger 4 and pipe 5 to vessel 1, after which the cycle recommences. The generation, or introduction, of vapour and its condensation is facilitated by a plate 8, spaced from the bottom 9. If the heating surface 9 is cylindrical, the plate 8 is replaced by a screen, which may be apertured, and baffles may be provided in the vapour-generating space. The screen may be of heat-insulating material, or lined with such material. A non-return valve 16 may be placed in the pipe 5. If a relatively cooler liquid is required in the exchanger 4, a shunt pipe 17 may be provided whereby the returning cool liquid passes directly into the vessel 2 to cool the liquid therein. A circulation of hotter liquid may be obtained by heatinsulating the wall 11 of the vessel 1. In a modification, Fig. 2, the pipe 6 is provided with a valve 21, and a closed vessel 50 is connected to pipe 5 to equalize pressure fluctuations therein. The pressure changes in the vessel 1 may be transmitted through pipe 23 to bellows 24 in a liquid fuel tank 30, whereby fuel is pumped through valves 26, 37 and pipe 28 to the burner container 22 having an overflow 29. Liquid may be similarly pumped for other purposes. In another modification, Fig. 4' (not shown), the heat-exchanger 4 receives liquid from the top of the vessel 1 and returns it to the top of the vessel 2. Several alternative constructions of the screen 8 are also described. The Specification as open to inspection under Sect. 91 comprises also a modification in which the screen 8 is spring-controlled and extends across the vessel 1, an opening in the centre of the screen being provided with a valve ; and a modification in which the vessel 1 is provided with a depending ring-shaped pipe communicating with the space above the screen 8 to obtain additional heating. This subject-matter does not appear in the Specification as accepted.

Filed: 1943-09-29
Abstract: Low temperature isoolefin-diolefin interpolymers are mixed with a curing agent, cured, replasticised by milling, mixed with a portion of uncured interpolymer and pressure worked.  The interpolymers are prepared by mixing a major proportion of an isoolefin having four to seven carbon atoms inclusive per molecule, with a minor proportion of a diolefin having four to twelve carbon atoms inclusive per molecule, cooling to -40 DEG  C. to -160 DEG  C. and polymerizing with a Friedel-Craft catalyst dissolved in a low-freezing non-complex forming solvent.  The pressure working may be by extrusion and the extruded mixture may be cured. The process may be applied to reclaimed interpolymers of the above type by shredding the reclaim, washing and milling, then milling a portion of fresh uncured interpolymer, mixing the milled reclaim with the fresh interpolymer, and then pressure working the mixture.  A curing agent may be added before the pressure working, and fillers may be removed from the shredded reclaim.  It is preferred that 1 to 10 parts by weight of the fresh interpolymer are present per part of milled reclaim.  The specified isoolefin is isobutylene and specified diolefins are butadiene, isoprene, piperylene, dimethyl butadiene, dimethallyl and myrcene.  Preferred proportions are from 70 to 99.5 parts isoolefin with 30 to 0.5 parts of diolefin.  The following compounding agents are specified, carbon black, zinc oxide, stearic acid, sulphur and tetramethyl thiuram disulphide.  Two examples are given of the process as applied to (a) isobutylene-isoprene and (b) isobutylene-isoprene and reclaim material.
