Patent GB-476795-A (GB)
Title: Improvements in or relating to rubber hydrochloride compositions
IPC: C08L15/02
Filed: 1936-03-09
Abstract: A vulcanized composition is produced by heating a mixture comprising rubber hydrochloride, sulphur, and a rubber hydrochloride heat-stabilizer of the kind set forth in Specification 476,733, e.g. basic oxides such as magnesium oxide. The admixture is preferably effected by milling, dry or with solvents.  The rubber hydrochloride may be crystalline or amorphous, the latter being preferably produced by the reaction of liquefied hydrogen chloride with rubber at low temperatures, and the former by passing gaseous hydrogen chloride through a rubber solution at ordinary temperature.  The rubber hydrochloride may be bleached with hydrogen peroxide or chlorine water, or the rubber itself may be so bleached.  Rubber from centrifuged latex or vulcanized rubber may be used.  The mixture may contain (1) a rubber age retarder such as hexamethylene tetramine, (2) a plasticizer such as dibutyl phthalate, butyl stearate or oleate or amyl benzene, transformer oil and other mineral oils, amyl lactate, methyl hexyl ketone, phenyl acetate, or a mixture of o- and p-toluene ethyl sulphonamides, (3) fillers &c. such as rosin, silica, asbestos, clay, whiting, barytes, blanc fixe, soft carbon blacks, ground cellulose, wood fibres or metal powder, (4) pigments, (5) rubber or polymerized chloroprene.  The milled mixture may be calendered into sheets or hot-moulded.  Reference has been directed by the Comptroller to Specification 443,100.

Filed: 1951-10-10
Abstract: 710,512. Ratchet gearing. THOMPSON PRODUCTS, Inc. Oct. 10, 1951, No. 23572/51. Class 80 (3) [Also in Groups XXVII and XXIX] A device tor causing relative rotation between two members 19, 20, Fig. 1, when an axial load therebetween exceeds a predetermined value, comprises balls 21 situated in arcuate grooves 24 in one member 19, the grooves being deepest centrally, and an annular spring 22 extending between the members such that it deflects when the load exceeds said value to engage the balls which roll to the centres of the grooves causing rotation of the spring and member 20 relatively to the member 19. The invention is described with reference to an internal combustion engine valve 12 wherein member 20 constitutes a seat for valve springs 14, 15. When the valve is closed, spring 22 is undeflected and carries the load due to springs 14, 15 from the member 20 to the member 19. When the valve is opened, the increased load deflects the spring 22 to engage the balls 21 which move to the deepest part 24a, Fig. 8, of the grooves, and cause ratation of the spring 22, member 20, springs 14, 15 and valve 12. Light springs 26, Fig. 5, urge the balls away from part 24a, the direction in which they are urged being reversible due to the shape of the grooves, whereby the valve may be rotated in either direction. Specification 594,828 is referred to.

Class 6(i) A spreading machine having a wheeled chassis with means for connecting the chassis to a vehicle, is provided with two shafts mounted fore-and-aft and rotated in opposite senses, a series of propellers of increasing blade size being mounted on each shaft. The spreader 1 is hitched behind a trailer 2 having a platform 3 which can be raised or lowered by chains 4 passing over pulleys 5 mounted on the chassis. Lifting power is transmitted by a shaft 7 and the platform can be tilted to leave a gap 8 at the rear end. The, spreader has a chassis 9 hinged to the trailer and supported by a castor wheel 13. Two propeller shafts 14, 15 are mounted in the chassis 9 and connected by gearing 16 to a shaft 17 driven through a clutch 18 from the shaft 7 or a power source mounted on the chassis 2. The shafts 14, 15 rotate in opposite directions and carry propellers 19, 20, increasing in size from front to rear of the spreader. A platform 21 mounted on the chassis is protected by a railing 22. Manure is loaded on to the platform 3 and the trailer 2 is then taken to the field where the spreader is attached and the shaft 17 connected by the clutch to the power shaft 7.

[Also in Group XXXIII] A jet pipe is truncated along planes 41, 42, Fig. 1 (18421/53), the missing part of the pipe being replaced by grilles 46, 47 of deflecting vanes, normally faired outside by a forwardly retractable member 51, and on the inside by vanes 43, 44. Forward movement of the grilles rotates vanes 43, 44 about pivot 45 to meet at the centre of the pipe and deflect the jet towards the grilles. In another version, the grilles and vanes 43, 44 are provided with racks interconnected by a pinion so that the vanes are swung inward by rearward motion of the grilles. Another embodiment is shown in Fig. 1 (23698/53), where the jet pipe 10 is flattened and widened at 11 to emerge from a wing as a shallow rectangular tube. In Fig. 14 (18421/53), the jet stream is bifurcated by a wedge 109 pivoted at 140 to deflect the jet through outlet 107 or 108 or both. In Fig. 18 (18421/53), is shown a modification in which a part of the jet stream is bled off by a vane 156 through guides 158 and a channel 154, to counteract the pitching moment produced by deflection of the main stream by grille 151. In normal flight, channel 154 is faired in by vanes 156, 159.

The handle B is moved to the required side before application of the apertured shank b to the latch &c. spindle (not shown). In moving the handle from one side to the other, spring D passes over a dead-centre position and arm c traverses an arcuate recess a provided in the plate, said arm finally abutting against one or other of two shoulders a<1>, a<2> terminating the recess. As shown, a single coiled tension spring is used, but two such springs may be used side-by-side, in which case adjacent ends of the springs are anchored to a connecting member pivoted on the plate or on the washer. Alternatively, a compression spring may be used, in which case the spring has an internal longitudinally disposed stalk, the exposed lower end of which slides in a fixed apertured lug, replacing stump E.

Abstract: 881,220. Drying apparatus. MONSANTO CHEMICALS (AUSTRALIA) Ltd. July 10, 1959 [July 14, 1958], No. 23787/59. Class 34(2) A method and apparatus for drying and classifying aspirin and like crystalline material comprises supplying the wet aspirin through a feeder 11, Fig. 1, into a primary fluidized bed of the material which is partially dried to a moisture content below which it is possible to maintain the bed in a fluidized state, displacing the upper surface portion of the bed through a spillway 16 down to a stand-pipe 17 into a lower secondary fluidized bed 3 having a lower fluid velocity than the primary bed whereby drying of the material is completed and the dried material is classified by stratifying into different masses of crystal-size ranges which are discharged through outlets 18, 19 at different strata levels in the bed. The beds are supplied with heated air from a blower 7 through a controlled inlet 9, which air enters through perforated screens 5, 6 supporting the beds, the cross-sectional area of the secondary bed being greater than that of the primary to lower the fluid velocity therethrough. The air is exhausted through a conduit 20 to a cyclone separator 21 wherein the crystalline fires are collected and a control 12 regulates the intake of wet material through the feeder 11 in accordance with the humidity of the exhausted air. Large agglomerates of the material which settle to the bottom of the primary bed flow across the bed to an outlet 15. In a modification the beds 1, 3, Fig. 2, are arranged side-by-side in chambers 2, 4 with the partially-dried material from the primary bed flowing over a spillway 16 which separates the beds into the secondary bed and each chamber has a controlled supply of heated air from a common blower 7 and an air outlet to a cyclone separator 21.
