Abstract: 361,607. Antidazzle screens ; fastenings. RAYNER, G. H., Wellesley, Warlingham, Surrey. Nov. 20, 1930, No. 35011. Addition to 337,054, [Class 103 (ii), Rail and road vehicles, Details applicable &c. to]. [Class 103 (ii).] An antidazzle shield 1 of the kind, e.g. as described in the parent Specification, which is held in alternative positions in contact with the wind-screen A by the co-operation of shaped lugs 7 with a resilient tension device such an extension 5 of a rubber suction cup 4, is adapted to be readily detachable from its supporting means. In the arrangement shown in Fig. 2, the shield 1 and lugs 7 pivot about a rod 6 connected to a pair of suction cups 4, while each lug 7 is furnished with a slot 10 having tapering edges and terminating in a bayonet-like recess 11. When the lugs are forced downwardly on to the rod 6, the latter rides up the inclined edges, extending the rubber necks 5, and finally snaps into the recesses 11 with the. rubber necks still tensioned. A ready detachment is effected by pulling the lugs away from the windscreen thus extending the tension device to the desired degree. In a modification, Fig. 4, the rod 6 is designed to engage spring clips 19 fitted on to the suction cups 4. Two antidazzle screens with appropriately shaped lower edges may be obtained from a single rectangular blank 2, Fig. 6, by cutting along a line 3, and the shields may be secured to the lugs 7 by interengaging slots 15 on the shields with slots 13 on the lugs, Fig. 3, and finally clipping or cementing over the top edges of the shields U-shaped metal strips 17.

Abstract: 883,053. Screening apparatus. SIMON Ltd., HENRY. Oct. 31, 1958 [Nov. 11, 1957], No. 35035/57. Class 117. A plansifter cabinet 1 houses six groups of sieve units 2 and is suspended from roof members by sets of canes 4; it is gyrated by an eccentric weight on a shaft 5 driven by a motor 6, and the material to be sifted enters the cabinet at the ducts 8 and the classified material leaves by the ducts 9. For each group of units an opening for their longitudinal withdrawal is provided; as shown in Fig. 1, the two doors which normally close the opening to the right hand group have been removed to indicate that opening and the clamping arrangement for the group of units. Each group is contained within an enclosure 11, and each sieve unit engages vertical corner extensions 12, 13 and is clamped there against by two vertical clamping members 14 which serve half the units in the group. Each member 14 is mounted on vertical pivots 15 on the extensions 13, and each pair of members are interconnected by two tie-rods 16 pivotally engaging claws 17 on the members and tensioned by turn-buckles; thus the faces 18 of the clamping members bear on the units. When the tie-rods are slackened and removed from the clamping members, the latter may be hinged clear of the opening or lifted from their pivots. After being clamped laterally the units are clamped towards the plansifter base by a linkage 20 pivoted to the enclosure and forced downwardly by a screw 21. A frame 24 provided with ducts for the passage of the material is pivotally suspended from the linkage and is forced downwardly by it and applies pressure to the parts 26 bearing on the units. The said parts form sealing extensions of channels x which provide passages for the material treated. To prevent leakage the latter, resilient material is located on the extensions 12, 13 which engages metal reinforcements 19 on the units.

Title: Improvements in electric insulated wires and cables
IPC: H01B3/30
Filed: 1937-12-18
Abstract: 509,760. Moulding plastic substances. BRITISH INSULATED CABLES, Ltd., WELBOURN, B., BRISLEE. F. J., and BAYLES, E. A. Dec. 18, 1937, No. 35100. [Class 87 (ii)] [Also in Group IV] An electric cable or conductor is insulated or protected by extruding upon it, so as to form a sleeve or layer, a mixture of a cellulose triester with a plasticiser or softener. The sleeve or layer may be applied directly to the conductor or upon an inner layer of other material. Extrusion is carried out at elevated temperature, e.g. 180-220‹ C. The plasticiser may be an aliphatic or aromatic substituted phenol such as o-phenyl phenol, benzyl phenol, octyl phenol, or dihydroxy - di - phenyl - dimethyl methane. Titanium dioxide or mica may be present as a filler. Benzyl alcohol or methylene chloride may be used as softener or solvent. Removal of softener at or during the conclusion of the extrusion causes the extruded tube to contract and grip the conductor which it surrounds. A similar effect may be obtained by applying reduced pressure to the interior of the tube as it comes from the nozzle so that it contracts upon the underlying surface. A power cable is obtained by extruding one or more layers of cellulose triacetate on to a stranded conductor and enclosing the insulated conductor, if desired after applying a braiding of cotton or other material, in a metal sheath. The cellulose ester composition may be used in the form of a moulding powder. Specification 362,481 is referred to.

Abstract: 449,608. Arrangement of vehicle wheel axles. HEGGADON, R. T., Boxhill, Crownhill, Plymouth. Feb. 25, 1935, No. 36926/34. [Class 108 (ii)] [See also Group I] An adjustable telescopic axle is provided particularly for rakes which are adapted to be expanded or contracted the axle being telescoped by the action of the ground, during longitudinal movement of the rake, on the wheels which are deflected outward or inwards from their usual parallel paths of travel. The axle A is provided with side axles B which are adapted to slide in brackets D, X, in which they are held in adjusted deflected position. Travel in the direction of the arrow would cause the side axles to slide inwardly while travel in the other direction would cause them to slide outwardly. Fig. 3 shows a modification in which the wheels c are pivoted to the side axles B which telescope into the main axle A. Fig. 4 shows another form in which the wheels are mounted on the main and side axles A, B by distorted mountings K, adjustment being effected by handles J. In Fig. 5, the main and side axles A, B are provided with deflected journals upon which the wheels are mounted by means of bushes bored as shown. Rotation of the bushes gives the desired deflection of the wheel.
