Title: Improvements relating to microporous ebonite sheet material
Inventor: HEMM CHARLES
IPC: H01M50/409
Filed: 1954-10-08
Abstract: Ebonite sheet material, such as is used for the manufacture of battery separators, is made by preparing an unfoamed gellable vulcanizable ebonite-forming compounded rubber latex (or a plurality of such latices), forming therefrom an assembly comprising at least two gelled layers, the gelling of the unfoamed compounded latex (or latices) from which these layers are formed being effected under conditions which prevent the ingress of bubbles of air or other gas into the latex (or latices), and subsequently vulcanizing and integrally uniting the gelled layers by heating the assembly whilst preventing escape of water from the pores of the gels.  The material may be prepared by assembling together two or more wet unvulcanized gelled latex sheets shortly after gelling and vulcanizing the assembly.  Alternatively a layer of ungelled latex is spread on a gelled latex sheet and gelled, further layers of ungelled latex being added if desired, each being gelled before the next layer is spread, and the assembly is vulcanized.  As a further alternative ungelled latex in one or more layers is spread on a composite sheet comprising two or more wet unvulcanized gelled latex sheets assembled together shortly after gelling, and the whole vulcanized.  The two or more layers of ebonite may differ in composition, e.g. in filler content, and at least one layer may contain up to 25 per cent by weight of diatomite or of ground waste microporous ebonite.  The sheet material may also be reinforced by interposing a piece of gauze or a number of pieces of narrow-gauge strip between one of the layers and the other (or another) layer. Specifications 698,613 and 741,395 are referred to.

Title: Improvements in or relating to motor propelled road vehicles
IPC: B62D55/02
Filed: 1925-11-17
Abstract: 266,391. Dawson, Sir A. T., and Buckham, Sir G. T. Nov. 17, 1925. Endless-track vehicles.-In a motor vehicle of the kind having endless-tracks and road wheels for alternative use the tracks and the wheels are driven through changespeed and reversing gear, and in order to permit the road wheels to be moved up and down relatively to the chassis in converting the vehicle from one state to the other, a universally-jointed shaft is interposed between a part of the driving mechanism on the chassis, and differential gear on the road-wheel axle. In the construction shown in Fig. 4, the main driving shaft D carries a pinion d gearing with pinions d<2>, d<3>, which are alternately clutched to their respective shafts D<2>, D' by means of a lever D<1> and clutches d<2xx>, d<3x>. The shaft D' drives the road-wheel axle d<5> through a telescopic shaft D' having universal joints d<2>x, d<4>, and the shaft D' drives the endless-track pulleys C<1> through a shaft D<7> having universal joints d', d<8> and worm and spur gearing. The invention is shown applied to the vehicle described in Specification 265,688, and the endless tracks may be driven through friction clutches, or epicyclic clutches may be employed as described in Specification 266,052. The endless tracks are automatically braked to avoid " creeping " when not in use, the means employed being those forming the subject-matter of Specification 266,393.

Title: Improved process for the manufacture and production of knock-stable gasoline by the destructive hydrogenation of carbonaceous materials
IPC: C10G47/00
Filed: 1936-10-27
Abstract: In the production of gasoline by the catalytic destructive hydrogenation of middle oils small amounts of ammonia, nitrogen bases, phenols, or materials furnishing these substances under the reaction conditions, are added during the hydrogenation in quantities adjusted so that the proportion of constituents boiling below 70 DEG C., contained in the gasoline produced is decreased but the total quantity of constituents boiling below 100 DEG  C. is substantially the same or is increased as compared with gasoline produced under conditions otherwise the same from the same middle p  oils in absence of said regulative substances.  Middle oils produced from coal may already contain the regulative substances and their amount may be regulated by partial purification, e.g. by a refining hydrogenation in presence of sulphides of heavy metals so that the quantity of impurities of a basic nature is from 0,1 to 0,5 per cent calculated as percentage by weight of nitrogen and 0,2 to 2,0 per cent in the case of phenols.  The catalytic hydrogenation is carried out at 300-500 DEG  C. under pressures of 50/500 atmos. and in presence of catalyst comprising sulphides, oxides, phosphates, and halides of heavy metals, in particular of Groups 5 and 6, preferably supported on carriers.  A middle oil obtained by the destructive hydrogenation of bituminous coal is hydrogenated at 400 DEG  C. and 200 atmos. pressure in presence of tungsten disulphide with a throughput of 1 kg. oil per hour per litre of catalyst.  A portion of the same oil is hydrogenated under more rigorous conditions, i.e. at 422 DEG  C. and the properties of the middle oils obtained in each case are shown in columns I and II: ..I.II .Specific gravity.0,876.0,856 .Aniline Point.40 DEG  C..48 DEG  C .Percentage of.. .phenols.0,25.0,03 .Percentage nitrogen.0,16.0,09 Each portion of the middle oil product is hydrogenated at 390 DEG  C. and 200 atmos. pressure in presence of tungsten disulphide on a carrier of bleaching earth pretreated with hydrofluoric acid and the following yields are obtained: ..I.II .Total yield of.. .gasoline calculat-.. .ed on the middle.. .oil..86 per cent.85 per cent ..I.II .Gasoline distilling.. .below 70 DEG  C. per.. .cent by volume.10,5.19,5 .Gasoline distilling.. .below 100 DEG C. per.. .cent by volume..55,0.59,5 .Reid vapour pres-.. .sure at 40 DEG  C..0,5.0,8

Patent GB-815954-A (GB)
Title: Vinyltin chlorides and bromides
IPC: C14C9/00
Filed: 1957-09-17
Abstract: Polymers may be prepared from vinyl tin chlorides and bromides of formula ViaSnXb, where a and b are each 1, 2 or 3 and (a + b) is equal to 4.  They also form copolymers with styrene, vinyl acetate, vinyl chloride, butadiene and acrylate esters.ALSO:Vinyl tin chlorides and bromides are prepared by reacting compounds containing the residues SnXa and SnXa+b, where X is chlorine or bromine, a=0, 1 or 2, b=2, 3 or 4 and a+b= 2, 3 or 4, the remaining tin valencies being satisfied by vinyl radicals.  The following reactions take place according to the relative molar proportions (Vi=vinyl): Vi4Sn+3SnX4 --> 4ViSnX3 Vi4Sn+SnX4 --> 2Vi2SnX2 3Vi4Sn+SnX4 --> 4Vi3SnX Vi3SnX+2SnX4 --> 3ViSnX3 2Vi3SnX+SnX4 --> 3Vi2SnX2 Vi2SnX2+SnX4 --> 2ViSnX3 Vi2SnX2+Vi4Sn --> 2Vi3SnX 2ViSnX3+Vi4Sn --> 3Vi2SnX2 ViSnX3+2Vi4Sn --> 3Vi3SnX ViSnX3 + Vi3SnX --> 2Vi2SnX2 The reaction may be carried out at temperatures between -10 DEG  C. and about 155-160 DEG  C. (the reflux temperature of the mixture), and the product may be isolated by distillation, usually under reduced pressure.  When preparing ViSnX3, it is preferred to use an excess of tin tetrahalide and to carry out the reaction at temperatures above 80 DEG  C.  The trivinyl tin halides are the least stable, and their derivatives (e.g. equations 4, 5 above) are preferably prepared without isolation of the trivinyl tin halides from the reaction mixture in which they are synthesized.  In an example, trivinyltin chloride is reacted with tin tetrachloride to give vinyl tin trichloride.  Other examples describe the preparation of divinyl tin dichloride, and trivinyl tin chloride according to the various equations set out above.

Abstract: 1457490 Measuring fluid-flow M H GROVE and J M E GROVE [trading as M & J DEVELOPMENT CO] 11 July 1975 29266/75 Addition to 1414108 Heading G1R In a meter prover sphere handling interchange, a sphere 1 moves from the outlet end of a meter run through an opening 36 into a plunger 44 which is moved by a rod 41, actuated by a double-acting cylinder-piston assembly 43, through a sleeve 38 to a position in which the sphere 1 can drop through an opening 33 into the entrance end of the meter run and, as the plunger 44 is moved into the sleeve 38, a seal is effected by a resilient seal 62 with the sleeve 38 which seal is taken over by a further seal 46 at the other end of the plunger 44 when the seal 62 leaves the sleeve 38 and the distance between the seals 62 and 46 is slightly greater than the length of the sleeve 38 so that a differential pressure is not built up within the sleeve 38 between the seals 62 and 46.
Patent GB-698691-A (GB)
Title: Mixing devices for liquid and gas
IPC: E03C1/084
Filed: 1950-11-29
Abstract: 698,691. Mixing appliances. AGHNIDES, E. P. Nov. 29, 1950 [Nov. 29, 1949], No. 29280/50. Class 14 (i). [Also in Group 11] A device for producing a coherent jet of liquid containing gas bubbles comprises a chamber connectable to the discharge end of a tube con- 'taining liquid under pressure, an orifice upstream of the chamber through which orifice a stream of liquid flows into the chamber with substantial velocity, a, gas port opening into the chamber for the entry of gas, induced by the liquid stream or supplied under pressure, finely perforated means in the path of the liquid stream after it leaves the orifice for finely breaking up the liquid, mixing it with the gas and uniting the aerated liquid into a coherent jet and adjustable means for.varying the total resistance of the device to the liquid and gas passing therethrough. The Specification describes a number of alternative constructions, as for example, the embodiment of Fig. 1 in which a chamber 100 is attached to a faucet 101 and in which liquid passes through a hole 102 and air enters through holes 106, a screen 108 being provided in a screw cap part 105 for finely breaking up, mixing and uniting the stream, the hole 102 containing a conical body 103 resting on the screen 108 so that it can be displaced vertically to vary the effective cross sectional area of the hole 102 by rotating the screw cap 105. The cross sectional area of the hole 102 is a minimum when the cap 105 is screwed to its uppermost position and in this case the liquid leaves the device as a divergent stream of droplets. As the cap is screwed downwards the liquid becomes aerated with progressively finer particles of gas until in the lowermost position when the cross sectional area of the hole 102 is a maximum no air is entrained and plain water emerges from the device. In other constructions the means for varying the total resistance of the device has a plurality of holes each having displaceable conical bodies, or comprises a pair of perforated discs one of which is rotatably or axially adjustable with'respect to the other. The resistance varying means is arranged in some constructions so that in one of its adjusted positions, the liquid stream is directed in the form of a spray like an ordinary shower from a portion of the outlet of the device not provided with the finely perforated means. Specification 625,084 is referred to.

Abstract: 911,083. Printing apparatus. ETIKETTENFABBIEK GEB. MOGENDORFF N.V. Aug. 24, 1960 [Aug. 25, 1959], No. 29288/60. Classes 100 (1) and 100 (4). [Also in Group VIII] A machine for printing a paper strip 44 in two colours, the imprints of .which may register, comprises two printing sets 22, 20 past which the strip is movable the set 20 being carried by a lever 15 swingable about a pivotable shaft 16 and connected to one end of a connecting rod 13 whose other end is connected to a crank disc 11 on a driving shaft 4 so that the set is rendered inoperative when the connecting rod is in a dead-centre position, Fig. 6, the other set 22 being carried by the connecting rod which is operatively connected to mechanism for intermittently advancing the strip. The printing sets 20, 22 which comprise rotatable printing discs associated with adjusting devices, are mounted on respective shafts 21, 23. Shaft 21 is carried by levers 15, 17 which are mounted on the shaft 16 to pivot therewith and are pivotally connected to the connecting rod 13 and an auxiliary connecting rod 18 by a pivot-pin 14. A crossmember 19 extends between the rods 13 and 18 so that the rod 18 and lever 17, respectively, follows the rocking movement of the rod 13 and the lever 15 resulting from rotation of the crank disc 11. The shaft 23 is constrained through a carrier 29 to reciprocate in a vertical path, the carrier being slidable on bars 27, 28, mounted vertically on a slide 24 which is reciprocable longitudinally of the machine and connected to the base plate 2 thereof via a pin-and-slot arrangement. The strip 44 is intermittently advanced past the printing sets 22, 20 through the interengagement of notches 52 thereon and a pawl 35 depending from a stirrup 33 adjustably mounted on the carrier 29. The pawl is both horizontally and angularly adjustable relative to the printing set 22 through respective knobs 40, 38a so that the entire strip-feed mechanism and the set 22 and, therefore, the distance between an imprint of this set and a line connecting two notches 52, may be adjusted. Inking ribbons 50, 51, of different colours and carried by the slide 24 are associated with the printing sets 20, 22. In operation the set 20 is caused to swing inwardly and effect an imprint on the stationary strip when the connecting rod 13 is approaching the outer dead-centre position of Fig. 4. In the production of two-colour labels this imprint forms the second colour pattern, the first having been already effected by the printing set 22 which operated whilst the set and the strip were moving forward together during the movement of the rod 13 from the position shown in Fig. 4 to that of Fig. 6. The respective imprints of sets 20, 22 are at fixed horizontal distances from the shaft 16 of Y and X which values may be chosen so that X is larger or smaller than, or equal to, Y.
