Title: Improvements in or relating to vehicle wheels
IPC: B60B17/02
Filed: 1932-09-30
Abstract: 397,685. Railway wheels. BUDD MANUFACTURING CO., E. G., 2500, Hunting Park Avenue, Philadelphia, U.S.A. -(Assignees of Budd, E. G. ; 2500, Hunting Park Avenue, Philadelphia, U.S.A.) Sept. 30, 1932, No. 27190. Convention date, Sept. 30, 1931.

Patent GB-405073-A (GB)
Title: Improvements in and relating to fluid-pressure brake systems
IPC: B60T13/16
Filed: 1932-09-30
Abstract: 405,073. Aircraft brakes. AVERY, W. L., The Blue House, Thorley, Bishop's Stortford, Hertfordshire. Sept. 30, 1932, No. 27243. [Class 4.] A fluid pressure brake system in which a piston or pistons of a pump which operates to supply fluid to a plurality of brakes is /are actuated by a hand lever or pedal includes means adapted after the brakes have been applied to isolate the fluid pressure supplies of the individual brakes from each other and from the pump. In one form, actuation of pistons la of master cylinders 1, 2 applies respectively the brakes to the rear and front wheel of a vehicle. The pistons 1a are actuated by the vehicle driver through bell-crank levers 4, 4a and levers 5, 5a mounted on shafts 7, 7a journalled in projections on the cylinders 1, 2 and actuated, respectively, by the hand lever and foot pedal. The bell-crank lever 4a is arranged through clutch members 9a and 9 to have driving engagement with the bell-crank lever 4 so that application of the foot pedal applies the front and rear brakes whereas application of the hand lever applies the rear brake only. The cylinder 1 communicates with the rear brakes through valves 15 associated with a flexible diaphragm 16 and provided with closing springs 17. Rotation of the shaft 7a by the foot pedal actuates the bell-crank levers and causes a cam surface 10 to depress a member 11, rotate a shaft 12 and raise projections 13 on the shaft to lift the valves 15 and admit pressure fluid to the brake cylinders. During actuation of the rear brakes only by the brake hand-lever a control 3a associated with the usual looking pawl 19a on the hand lever moves a rod 18, which engages a projection 20 on the shaft 12, axially in the shaft 7, to open or allow the springs 17 to close, the valves 15. Closure of the valves 15 isolates the master cylinder from the brakes thus allowing the car to be parked under the influence of the rear brakes. In order to maintain the system full of fluid and to allow air to escape, one of the pistons is arranged in its upper position to engage an adjustable screw 23 in a lever 24, articulated on its cylinder, to lift a rod 26 and open two valves 22 one for each cylinder. The screw and lever mechanism may be duplicated and each valve 22 operated independently. In a modification, shown in Figs. 6, 8 and 10, in which the brake system is applied to aircraft, a hand lever 32 actuates a piston 36 in a master cylinder 35 and the locking pawl operates a rod 51 so that on its being lifted the rod 51 moves axially to open through a lever 52 valves 41, 41a against the action of springs 42a to allow pressure fluid to pass to the brakes and to two hand or foot operated superchargers 34, 34a, associated one with each wheel, providing for differential application of the brakes. A reservoir cylinder 33 is provided.

Title: Method of drawing and calibrating a glass tube
IPC: C03B23/07
Filed: 1973-06-07
Abstract: 1425057 Drawing glass tubes CABL-ZEISSSTIFTUNG [trading as JENAER GLASWERK SCHOTT & GEN] 7 June 1973 [15 June 1972] 27287/73 Heading C1M In a method of drawing and calibrating a glass tube, a glass tube drawn from molten glass is passed while still plastic through a calibrating station comprising a plurality of shaping elements concentrically disposed round the axis of the tube to co-operate therewith to determine the external diameter of the tube, the shaping elements being rotated about the axis of the glass tube. The shaping elements may be rolls which rotate also about their own axes or may be longitudinal fins having a lateral edge region to engage the glass tube. A gas cushion, which acts as a lubricant, may be introduced between the elements and the tube. The glass tube may be of larger diameter than required, or smaller, in which case the atmospheric pressure outside the tube is lowered to expand the tube into engagement with the elements. As shown in Figs. 1 and 3, a glass tube 160 is narrowed to a predetermined diameter at region 164 by engagement in plastic zone 162 by elongate rolls 1 connected by levers 2 to rods 3 mounted in a cage 150. Cage 150 is mounted for rotation about the axis of tube 160 in a stationary frame 200. For narrower tubes, the cage is connected to suction means to expand the tube to engage the rolls 1. As shown in Fig. 4, the rolls 1 may be simultaneously concentrically adjusted for different diameter glass tubes. Each rod 3 is mounted in rings 28 and 13 at top and bottom, forming part of cage 150, and passes through an annular ring 10 at a middle region and has a pinion 4 keyed thereto. Pinion 4 meshes with internal teeth of a toothed ring 6 the external teeth of which mesh with a pinion 22 on a shaft 19 journalled in eyelets 110 in frame 200 and ring 10 meshes with a pinion 20 on shaft 19, the rings 6 and 10 being interconnected by parts 8 and 9 which slide on each other to allow relative displacement of the rings 6 and 10. Pinion 22 is keyed to move on shaft 19 on a steeply inclined helical groove and is moved by a setting spindle 25 via an element 100 and against the action of a spring 102. The movement raises or lowers ring 6 relative to ring 10 to turn rod 3 and thereby swing the attached roll 1 inwardly or outwardly. All rolls 1 are similarly mounted and interconnected by the rings 6 and 10 so that there is simultaneous movement. An alternative means for simultaneously adjusting the rolls 1 is disclosed in Fig. 5 (not shown).

Patent GB-489019-A (GB)
Title: Improvements in or relating to the treatment of textile materials
IPC: D06Q1/00
Filed: 1936-10-15
Abstract: Textile materials capable of being coloured to show pattern effects are obtained by subjecting to local or differential heat treatment textile material comprising an organic derivative of cellulose so as to reduce the dye affinity of the cellulose derivative. Alternatively, cellulose organic derivative yarn is subjected to heat treatment and is then incorporated with an untreated cellulose organic derivative yarn in a textile fabric. The heat treatment may be carried out under dry or moist conditions and at a temperature above the fusion point of the cellulose derivative, and it may be performed before or after twisting the filaments into yarns, or after fabric formation. The cellulose derivative may be cellulose acetate, formate, propionate, or butyrate, or ethyl, methyl, or benzyl cellulose. Textile materials containing weighted cellulose derivatives may be treated.  Weighting, particularly if silicon compounds are used, increases the range of dyestuffs, including direct and acid dyes, which may be used.  Compounds of tin, antimony, lead, zinc, and titanium may also be used as weighting agents. Continuous materials may be heat treated by running them over or between one or more heated rollers.  Local treatment may be effected by ironing, or using a heated stamp.  Fabrics or yarns in sheet formation may be printed with a heated printing surface which may or may not carry dyestuffs or printing colour.  Photographic designs and delicate shading are accurately reproduced by passing a weighted cellulose acetate fabric between nip rollers, one of which is engraved and heated, and then dyeing the fabric with direct colours. In an example, a fabric consisting of cellulose acetate yarns which have been weighted by successive treatment with stannic chloride, sodium biphosphate, and sodium silicate is passed between nip rollers, one of which is engraved with a raised design and heated. The material is then dyed with a direct or acid dye.  Portions of the fabric which have been in contact with the heated raised design of the roller remain colourless while the remaining portions are coloured.
