Title: Improvements relating to stabilisers for vehicles
IPC: B60G21/05
Filed: 1935-07-18
Abstract: 457,142. Vehicle spring-suspensions. ALLEN, B. J., Langladure, Blythe Bridge, Staffordshire. July 18, 1935, No. 20509. [Class 108 (ii)] In an arrangement for stabilizing the body, and distributing the load to the wheels, of a motor &c. vehicle of the kind in which the axle ends or semi-axles at opposite sides of the vehicle are interconnected by displaceable transmission means such as a liquid, freelymoving balls &c. the transmission includes an automatic locking and unlocking abutment which is adapted to be locked in position when the thrusts on the opposite wheels are balanced, and to be unlocked when the thrusts are unequal. In the construction shown in Fig. 1, the wheels 2, 3 are mounted on arms at the ends of an axle 4, and the arms are fitted with plungers 6, 7 which operate in curved tubes 8, 9 containing freely moving balls. At the inner parts of the tubes 8, 9 the balls contact with further plungers 11, 12, between which are disposed springs 40, 41 and the automatically releasable abutment 10a. Minor road shocks are absorbed by the springs 40, 41, but heavier shocks on one side only effect a displacement of the abutment 10a to a new position in which the thrusts are balanced. The abutment 10<a> is itself constituted by a sleeve 36, Fig. 6, slidable in the tube 10 or 37 and provided with a number of recesses 35 containing balls 34, and an inner wedge-shaped element 32 adapted normally to force the balls 34 into contact with the tube 37. Relief of the pressure of the springs 40, 41 on one side permits an internal spring 44 to become operative to release the balls 34. Other forms of releasable abutment may be employed. The invention may be applied to vehicles having independently sprung wheels, and oil or other liquid may be substituted for the freely moving balls as a pressure transmission means. Additional load springs may also be incorporated, the initial compression of which may be adjustable, e.g. in association with the steering-mechanism. In the case of independently sprung wheels, these mav be associated with a transverse leaf spring, while the displaceable transmission means may consist solely of helical springs in combination with the releasable abutment 10a.

Title: Improvements in or relating to vehicles for carrying perishable goods
IPC: B61D27/00
Filed: 1929-07-04
Abstract: 338,855. Robbins, T., Dehler, F. C., and Silica Gel, Ltd. July 4, 1929. Ventilating vehicles; forced ventilation; air, heating.-In a vehicle, for perishable goods such as a rail or road vehicle, a ship or an aircraft, there is provided means for delivering a supply of air to the interior of one or more containers for the goods and means for removing moisture from the air prior to its delivery to the container, said means comprising a bed of silica or like absorbent gel. As shown, a container 11 mounted on a railway vehicle is supplied with air through pipes 14, 15 and a removable receptacle, 12 containing absorbent gel, by means of a fan 16 driven by a wind motor 18. The volume of conditioned air passing to the container is automatically controlled by a brake comprising a block 20 acting on a rim on the wind-motor spindle and mounted on a lever 200, the other end of which is attached to a length of gut or similar humidity-sensitive material 21. To increase, the sensitiveness of the device., a relay may be interposed between the gut and the brake. In a modification the air may be circulated by means of a wind-scoop, and a stream line exhauster. In other modifications the air circulating fan is driven from one of the vehicle axes or is driven by a motor working, from an accumulator charged by a dynamo driven from the vehicle axle. In this case the fan may be used when the vehicle is stationary. Fig. 6 shows a further modification in which, in addition to drying the air by adsorbent gel, the air is compressed by a compressor 43 and delivered into a cooled receiver 44 having a moisture trap, before it enters the container by a pipe 45. Specification 8053/12 is referred to.

Patent GB-1387914-A (GB)
Title: Automatic push button tape embossing machine
IPC: B41J5/04
Filed: 1972-05-04
Abstract: 1387914 Selective embossing apparatus DYMO INDUSTRIES Inc 4 May 1972 [10 May 1971] 20875/72 Heading B6F Embossing machine.-The machine includes a rectangular key board 14 and an embossing wheel 23 having about its periphery an annular array of embossing dies. The wheel 23 is normally continually rotated during operation of the machine, and each of the keys (71, Fig. 7) has a stem which co-operates with stop 91 on the wheel 23 for interrupting rotation when the key is depressed. A cam assembly (101, Fig. 8) is clutched in when the embossing wheel is brought to a halt to then cause the character positioned at an embossing station to be embossed on the tape and also to advance the tape through the embossing station. A serrated wheel 32 cooperates with a nip roller 37 to advance the tape. The drive of the wheel 32 is derived from the cam assembly which oscillates a bell-crank (137, Fig. 8) which is only connected to drive the wheel 32 via a coil spring clutch (136, Fig. 9) on the return stroke. Variable spacing is achieved with a stop ring (148, Fig. 18) on the underside of the embossing wheel 23. The periphery of the stop ring (148) is stepped so that portions thereof extend at varying radial distances from the shaft of the embossing wheel 23; these distances representing the widths of the various characters. A sensing slide (138, Fig. 9), connected for movement with the bell-crank (137) via a link (141), moves into contact with the stop ring (148) on the forward stroke of the bell-crank, thereby governing the amplitude of the stroke so that the return stroke rotates the wheel 32 the correct amount for a given character. Manual spacing is acheived with knob 42 connected to the shaft of wheel 32. Interword spacing is achieved with key 41 operating a coil spring clutch (192 to 196, Fig. 9). Cut-off is achieved when a key 39 is depressed causing the knife (Fig. 15) to be cam operated. Prior to cut-off, the feed wheel 32 is advanced with link (216, Fig. 15) so that the last embossed character is clear of the knife. The cam assembly also causes an index wheel (131, Fig. 8) to engage within notches 132 in the periphery of the embossing wheel 23 to lock the wheel in position during embossing. Keyboard construction. Fig. 5.-The keys 71 are arranged in a rectangular array (Fig. 4). Each key stem includes a conical section 83 which passes through an associated aperture in a locking plate 76. When a key is depressed, the conical section 82 forces the locking plate 76 to one side against the bias of springs. The key is retained in the fully depressed position when the locking plate 76 returns to its initial position behind the base of the conical section.

Title: Improvements in the production of hydrogen
IPC: C01B3/22
Filed: 1931-07-22
Abstract: In a process whereby hydrogen is obtained from gas containing it and hydrocarbon gases, e.g. coal or coke oven gas, by separating the gas into its constituents, removing the hydrogen, decomposing the hydrocarbons in an incandescent fuel bed and returning the resultant gas to the separation stage, the carbon deposited on the fuel is utilized in the production of water gas by intermittent treatment with steam introduced separately or together with the hydrocarbon gases; the water gas may be passed to the separation stage or, together with any carbon monoxide removed in the separation stage, may be catalytically treated with steam and passed to the separation stage.  In an example, coke oven gas containing mainly hydrogen and methane with small amounts of illuminants, ethane, carbon monoxide and dioxide and nitrogen is treated to remove tar and sulphur and compressed, benzol is removed by cooling with ammonia and the carbon dioxide absorbed by water or lye; the gas is then further compressed and cooled and the hydrocarbons and carbon monoxide separated.  The nitrogen may be allowed to remain if the hydrogen is to be used for ammonia synthesis.  In a modification, the carbon monoxide is absorbed in a solution of cuprous ammonium formate and the stripped gas passed to the separation stage.  The cracked hydrocarbon gas with the water gas produced by alternate and simultaneous treatment with steam is also passed to the carbon monoxide absorber, from which the carbon monoxide is recovered at intervals and treated catalytically with steam.

Filed: 1946-07-15
Abstract: 614,584. Tippers. HEWITT, B. W. July 15, 1946, No. 21142. [Class 78 (iv)] A tipper comprises a main platform 1 mounted in bearings 2 within a shoot 13 so that it can be rotated to discharge into the shoot the contents of a car on the platform, and two auxiliary platforms 3, 4 at right angles to the main platform. The auxiliary platforms 3, 4 are braced to the main platform 1 by brackets 8, 9 which also support an inclined steel plate 10 which during the first part of the rotation of the platform 1 reaches almost to the upper cylindrical surface of the shoot 13 and thus prevents premature discharge of the load. Angle irons 11 and plates 12 hold the car in position on tracks 6 or 7 during tipping. The platforms are rotated by shrouded spur wheels 15 engaging shrouded racks 16, the weight of the platforms and cars being borne by the shrouds, the racks 16 bearing by means of rollers 20, 22 on steel tracks 21, 23. The racks are reciprocated by a hydraulic ram 18 which during its stroke operates valves to slow the movement of the platforms after the initial movement. In use a loaded car is run onto the platform 1 as shown and the platforms are rotated anticlockwise through 180 degrees to discharge the car and to bring the tracks 7 on the platform 1 opposite tracks 5 from which a further loaded car may be run onto the platform. During this motion platforms 3 and 4, which extend almost to the sides of the shoot 13, prevent dust escaping. The platforms are then rotated back to their initial position so discharging the second car and enabling the first to be replaced by a further loaded car. Cars may also be accommodated on tracks 35 on platforms 3 and 4 which provide for access across the shoot.
