Title: Vulcanizable composition
IPC: C08C19/32
Filed: 1969-02-11
Abstract: 1,235,945. Curing polymers containing allyl halide groups. POLYMER CORP. Ltd. 11 Feb., 1969 [22 Feb., 1968], No. 7335/69. Heading C3P. Liquid polymers having allylic halide groups are mixed with a polyamine salt of a polycarboxylic acid and then heated to cure them. The exemplied polymer is polybutadiene having terminal allyl halide groups made by Specification 1,140,764. Suitable curing agents are the salts of 1,3-di-4-pyridyl propane with succinic acid, oxalic acid, and adipic acid and the salt of hexamethylene diamine and succinic acid. The compositions may be made more storage stable by the addition of desiccants such as calcium oxide. The compositions may also contain basic lead phosphite, epoxy resin, and aminosilane treated clay.

Title: Apparatus for imparting a reciprocating motion to an article
IPC: F16H21/16
Filed: 1972-02-17
Abstract: 1378783 Brush making machines G B BOUCHERIE NV 17 Feb 1972 [15 March 1971] 7477/72 Heading A4K [Also in Division F2] A system of levers for producing different displacements of a member 1 (in, for example, a feed mechanism of a brush making machine) in response to rotation of a cam 23 is constructed as shown Fig.1, the cam 23 moving a horizontal (as shown) rod 20 upwards which, through rods 18, 19 rocks levers 14, and 15 about pivot points 12, 13 to raise rods 27 and 28 (constrained to move vertically) having stop members 31, 32 at their upper ends. Springs 50, 51, Fig.12 urging a rod 2 downwards holding the pivots 12, 13 stationary to permit this. Once the rods 27 and 28 have reached their maximum height, one or both of the stop members 33, 34 can be moved to hold either or both of rods 27 and 28 in this position so that, on further rotation of cam 23, with consequent lowering of member 20, one or both of levers 14, 15 will tilt about point 25-26, and so raise rod 8 or 9 or both and so raise member 1, either by an amount determined by the cam displacement only (both stops 33 and 34 actuated), by an intermediate amount (one stop actuated) depending on the ratio a to b of the two arms of lever 5, or the displacement is zero (no stop actuated). In the arrangement shown in detail in Fig.12 two such arrangements are utilized, each member 2 being connected to the ends of a further lever 38, a member 40 being connected to an intermediate point of this and having the member 1, which comprises two racks 42 and 43 at its opposite end. The member 20 is here constituted by a rod 35 which pivots about its axis. The racks 42 and 43 each act on a separate pinion, such as 62, these pinions each having a pin, 65 with a sickle shaped pawl, 66, 67 pivoted on it. Each pawl 66, 67 co-operates with a rack 68, (69) Fig.17 (not shown), to rotate a shaft 64 in one sense or the other, selection of the pawls being through a member 70, a member 76 being moved by a screw 75 in response to this rotation. The movement of the member 70, and the stops 33 and 34 is either by pneumatic or hydraulic pistons and cylinders or by solenoids (devices 61, 72), and selection of them permits sixteen amplitudes of movement (in either direction) of member 76, in response to movement of cam 23. Three or four such devices can be used to perform movements in different planes in a brush making machine.

Abstract: 539,126. Sheet-delivery apparatus. IGRANIC ELECTRIC CO., Ltd. RAPLEY, H. H., and RAWLINS, G. H. April 30, 1940, No. 7735. Addition to 508,227. [Class 100 (i)] [Also in Group XXX] In a device for accurately spacing newspapers or the like on conveyers, in which the articles are first arranged on the conveyer at longer intervals than those required and the intervals are subsequently shortened by the articles catching up with spaced teeth or the equivalent moving in a substantially straight line beside the conveyer, as in Specification 508,227, means are provided for adjusting the phase of the teeth relatively y to the approaching articles. The chain carrying the teeth is driven through a sprocket 3, by a chain 1 passing over a driving sprocket 2 and sprockets 4, 5, the sprockets 5 being adjustable so that the phase of the teeth is adjusted. As shown, the sprockets 5 are mounted on a common chassis 6, slidable in guides 12, 13 and adjusted by a hand-wheel 11, carrying a screw engaging a projection 10, on the chassis. The adjustment may be effected while the machine is running and the chassis may move against a scale calibrated in accordance with the thickness of the newspapers conveyed. The guides 12, 13 are mounted on cross plates 14, 15 supporting the sprockets 4 and adjustably connected to plates 17, 18, 19 on fixed members 26, 27. The adjustment may alternatively be applied to the conveyer for the newspapers.

Abstract: 882,877. Collapsible spindles. WITTONJAMES Ltd. March 4, 1960 [March 6, 1959], No. 7870/59. Class 100(1) A bung assembly for fitting in an aperture in a reel core comprises a sleeve 29 of resilient material, one or more teeth 32 and mechanism to compress the sleeve and to displace the teeth from a retracted position so that the sleeve grips and the teeth bite into the wall or walls defining the aperture. As shown, a screwed shaft 24 engages the threaded bore of a cup-shaped member 27 slidable on the nose portion 28 of a stub spindle 23. Rotation of the shaft, by a hand wheel, not shown, in the appropriate direction, causes pivoted teeth 32 engaging slots 31 in the member 27 to be swung outwardly and the sleeve 29 to expand radially outwards. In a modification, described with reference to the Figures accompanying the Provisional Specification, the assembly is arranged to be keyed to a stub spindle and the teeth which are slidable radially are projected outwardly by a coneshaped nut.

Title: Improvements in or relating to cigarette machinery
IPC: A24C5/32
Filed: 1926-03-23
Abstract: 272,997. Molins, W. E. March 23, 1926. Cigarette-making machines. - Apparatus for delivering cigarettes in orderly arrangement from a continuous-rod machine comprises an endless belt 4 travelling at a greater speed than that of the rod, and a vane 7, rotated at such a speed as to deflect alternate cigarettes on to an endless belt 19 ; alternatively, a pusher-piece may replace the vane 7. The belt 4 passes through a guide which causes it to take a trough-like form and grip the cigarettes which are guided on to it by a guide 5 after they have passed over a bridge 2; the cigarettes are then separated axially and pass under a guide. The vane 7 comprises a number of teeth 8 and is rotated by a shaft 9, a spring 10 allowing relative axial movement so that it declutches in the event of a cigarette becoming jammed. The forward sides of the teeth 8 are convex and they rotate between concave teeth 11 of a deflector which causes the cigarette to be braked both longitudinally and transversely and to be deposited on the belt 19 as shown in Fig. 4. Beyond the end of the belt 4 a second vane 20 rotates on the shaft 9; this vane is shaped helically so as to brake the cigarettes and deflects them on to a shoot 21 which deposits them on the belt 19. Alternatively, the belt 4 may be carried over the complete width of the belt 19 and a duplication of the vane 7 and deflector 11 substitute for the vane 20. A flexible element 22 aligns the cigarettes on the belt 19
