Title: Improvements in power transmission systems for railway vehicles
IPC: F16H47/07
Filed: 1936-02-17
Abstract: 470,571. Hydraulic driving gear for rail vehicles. SINCLAIR, H. Feb. 17, 1936, No. 4832. Convention date, Feb. 16, 1935. [Class 79 (ii)] A transmission system for rail vehicles comprises a single power unit A driving two axles F<1>, F<2> through separate hydraulic gears C', C<2> of the kinetic type, the driven shafts L<1>, L<2> of the hydraulic gears being coupled together by a constantly-acting non-positive coupling G. The coupling G may be a slipping friction clutch or, as shown, may comprise friction wheels g<1>, G, g<2> kept in driving contact by a spring Q. The axles are thus always coupled by the friction coupling G. In the construction shown in Fig. 1, each hydraulic gear comprises a torque-converter C<1> or C<2> and an hydraulic coupling D or E. At starting the two torque-converters are filled and the couplings are emptied, and each torque-converter drives its own axle, the friction coupling G serving merely to damp out vibrations. When a certain speed is reached the converters C<1>, C<2> are emptied and the coupling E is filled. This drives the axle F<2> through reducing gears M<2>, N<2>, and the axle F<1> through the coupling G, which also forms a reducing gear, and equal gear wheels M<1>, N1. At a still higher speed the coupling E is emptied and D is filled, this coupling driving the axles F<1> through the 1 to 1 gear train M<1>, N<1> and F<2> through the gear trains G and M<2> N<2> which cancel out each other. Reversing gears P<1> P<2> are provided on the axles. In a modification the hydraulic couplings D, E are replaced by torque-converter of different ratios.

Title: Improvements relating to the treatment of grain in silos
Inventor: JOLLEY FRED RABY
IPC: B65D88/74
Filed: 1949-02-25
Abstract: Grain is treated in silos by first blowing air, pre-heated to a temperature which will not damage the grain e.g. 30-40 DEG C, through the grain at rest in the silo by means of the usual ventilating equipment whereby the grain is heated in a comparatively short time and with partial driying to approximately the temperature of the heated air, shutting off the air heating means and blowing in air at normal temperatures e.g. 10-15 DEG C. whereby on account of the large temperature difference a further drying of the grain takes place with simultaneous cooling to the temperature of the ingoing air. Specification 684,316 is referred to.

Title: Improvements in or relating to the steering of vehicles, ships and aircraft
IPC: B62D5/06
Filed: 1931-02-19
Abstract: 361,212. Steering ships and aircraft. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. Feb. 19, 1931, No. 5218. Convention date, March 7, 1930. [Classes 4 and 114.] Power-assisted steering gear for vehicles, ships, and aircraft comprises one or more fluid-pressure servomotors having cylinders controlled by the displacement of a member coupled with the steering wheel or tiller, in which the actuating pressure on the servomotor piston is relieved. as soon as the desired position of the steering wheels &c. is reached. In the construction shown applied to motor vehicle the servomotor cylinder 9 is connected by vacuum pipes 14, 15 with the induction pipe 18 of the vehicle engine, and the valves 12, 13 controlling the pressure in the cylinder are operated by electromagnets controlled by contacts 39, 40 carried by the steering. hand-wheel 26. The steering wheel is connected to the steering shaft 1 by a lost motion coupling 27, 28. The shaft carries a frame 23 having contacts 32, 33 connected to a battery 36. One of the valve boxes 12 is shown in Fig. 3 and comprises a casing 41 with a cover 42, a diaphragm 48 being clamped between the cover and the casing. The diaphragm carries a plate 47 which forms the armature of an electromagnet 44 and has valve faces 54, 55 respectively adapted to seal a bore 56 in the cover connected by, perforations in the diaphragm to the vacuum pipe 14, and a bore 45 open to the atmosphere through holes 53. The valve stem 46 is guided in the casing at 50. The 'valve is shown in its normal position, in. which it. is pressed against the' bore 56 by atmospheric pressure and the adjacent cylinder end is open to the atmosphere through a bore 51, space 52 and bore 45. The steering wheel is normally maintained in the central position shown in Fig. 1 relative to the steering shaft 1 and the frame 23, by springs 30, 31. When the steering wheel is turned counterclockwise (say), the contact 39 contacts with 32 and closes the circuit for the magnet 44 through wire 21. The magnet is energized and the.valve moves to the right shutting off the cylinder end 10 from the atmosphere and opening it'to the vacuum pipe 14. The piston 8 is thereby moved to the right, the steering wheels (not shown) are actuated by a link 5, and the steering shaft 1 is turned through the steering gear 2 with a "follow-up" motion, so that as soon as the motion of the steering hand-wheel is stopped the contact 32 moves away from contact 39, the magnet is de-energized and the cylinder end 10 is open to the atmosphere again. In order to avoid sparking at the contacts lamps 57, 58 are placed in parallel with the valve magnets.

Title: Rubber-like material and process of making same
IPC: C08F36/04
Filed: 1929-02-18
Abstract: 333,901. Hultman, E. W. Feb. 18, 1929. Caoutchouc and like polymerized hydrocarbons, synthetic, production of.-A rubber-like substance is prepared from mineral oils substantially free from constituents boiling below 205‹ C. by subjecting the oils to a polymerizing process with a catalyst comprising cerium or tin oxide at about 90‹-95‹ C., cooling, passing therethrough a hot reducing gas activated by previous passage over a catalyst such as nickel and palladium at 205‹ C., then subjecting to a halogenating agent such as chlorine, bromine or boron fluoride, allowing to stand for some days, and finally separating the soft rubbery product from the bulk of the oily material. Any sulphur originally present in the oil will mostly be precipitated with the rubberlike product and should be allowed for in subsequent treatment of the product with sulphur for vulcanization. In an example, a Pacific Coast crude oil freed from constituents boiling below 200-210‹ C. is treated at about 90-95‹ C. with cerium oxide or stannic oxide in proportion of about ¢ pound of oxide per barrel of oil. The mixture is cooled to 25-30‹ C. and the oil may then be decanted off from the catalyst. Carbon monoxide or methane or a mixture of these, which has been activated by passing it over finely divided nickel or palladium heated to 200-210‹ C., is then bubbled through the oil in the proportion of about 1 cubic foot of gas per gallon of oil, and the oil is allowed to stand for about 24 hours to permit escape of the gas. Finally the oil is substantially saturated with chlorine and allowed to stand for two to fifteen days when a rubberlike material coagulates which is separated from the unconverted oil and washed with acetone or other solvent or with an alkali. In another example the reducing gas consists of a mixture of 90 per cent carbon monoxide and 10 per cent methane activated by passing over a catalyst consisting of fused magnesium sulphate containing 1.5 per cent of finely divided metallic nickel and a trace of palladium.
