Abstract: 1,037,545. Containers for radio-active materials. TECH DEL Ltd. Sept. 9, 1964 [June 12, 1963], No. 23476/63. Heading H5R. A shielding container for a radio-active pellet 13 comprises a spherical shielding member 2 carrying the pellet 13, which member 2 fits into the hollow of a cup-shaped shielding member 1 and which rotates within this member 1 to carry the pellet from an exposed to a shielding position (or vice versa). The pellet 13 is attached to the end of a tube 12 carried by a plunger 10 which is separated from a plunger 9 by a fluid such as oil, the plungers (preferably of tungsten) being contained in mutually perpendicular passageways 8, 7, respectively. Abutting against the end of the pellet is a spring 16 mounted in a radiation permeable sleeve 16 of, e.g., fibreglass, which is fixed with respect to member 1. By moving the plunger 9 from outside the shielding, the pellet may be withdrawn under the action of the spring 16 from an exposed position where it is used for panoramic radiography, to a partially shielded position within the passage 8, in which position, with sleeve 15 removed, it can also provide a beam of radiation. For maximum shielding, the member 2 is rotated on trunnions 4 in the bearings 5, through 180 degrees. The members 1, 2 may be of uranium.

Title: Improvements in fuel injection mechanism for internal combustion engines
IPC: F02M57/02
Filed: 1923-10-31
Abstract: 229,966. Blackstone, G. M., Carter, F., and Carter, E. Oct. 31, 1923. Spring throzv actuated pumps. - Fuel is supplied by a pump in measured quantities through a non-return valve d<1> to a chamber d in communication with a chamber c<4> surrounding the injection valve c and with the pressure chamber of a pump plunger d This plunger is in contact with a second plunger e, having a sliding cap e<4> between which and the head x of the plunger e is a spring e<1>. During the supply of fuel to the chamber d, both plungers together with the cap a<4> are moved outwards from left to right. Immediately previous to injection a roller #<1> on a camshaft-actuated lever f contacts with the cap e<4>, and since the plungers e and d<3> are unable to move owing to the presence of fuel in the chamber d, compresses the spring e<1> until a projection h on the lever f engages an adjustable, tappet h<1>. When this occurs the arm of a bell crank lever h<3> is moved out of contact with the outer end of the fuel injector valve c, thus removing from the valve the pressure of the spring h<2>. The pressure of the fuel in the chamber c<4> is then sufficient to open the injection valve' c against the pressure of another spring (not shown) and injection takes place, the plungers e and d<3> moving from right to left under the influence of the spring e<1> at a speed independent of that of the engine. A buffer spring e<5> to check the outward movement of the plunger, and a valves i to permit the escape of imprisoned air at starting, are provided. Compressed air or other gaseous fluid may be used in place of the spring e<1>, the fluid being repeatedly compressed and allowed to expand. Specification 228,261 is referred to.

Title: Improvements in methods of adhering textile materials to natural or synthetic rubber
IPC: C08J5/06
Filed: 1954-08-17
Abstract: 751,195. Attaching rubber to textiles. UNITED STATES RUBBER CO. Aug. 17, 1954 [Oct. 29, 1953], No. 23864/54. Class 70 [Also in Group VIII] A method of adhering textile material to natural or synthetic rubber, as in the manufacture of hose, belts, and tyres, comprises applying dry unreacted resorcinol as such and dry unreacted paraformaldehyde as such to either or both the textile material and the rubber, or applying either of the said compounds to the textile material and applying the other to the rubber, subsequently bringing the rubber and textile material together, and thereafter heating the assembly to form resorcinol-formaldehyde resin in situ. The resorcinol and paraformaldehyde may be mixed with the rubber stock on a mill, the temperature being maintained low enough to prevent reaction between the resorcinol and paraformaldehyde. It is, however, preferred to dust paraformaldehyde on to the surface of the textile, or to expose the textile to the vapour of sublimating paraformaldehyde, and to mix the resorcinol with the rubber stock on a mill. The amounts of resorcinol and paraformaldehyde deposited in the rubber and on the textile, respectively, are preferably each one tenth to eight per cent by weight. The textile may be of cotton, rayon, or nylon, and the synthetic rubber may be a butadiene-styrene copolymer. In one manner of carrying the invention into effect paraformaldehyde is deposited on rayon tvre cords 12 by passing them upwardly in parallel side-by-side relation via a slit 13 through a hopper 10 containing powdered paraformaldehyde 11. Excess paraformaldehyde is scraped off by blades 14 and loose particles removed by vacuum cleaners 15. The rayon cords, having a deposit of 2 per cent by weight of paraformaldehyde, are then fed into a calender 17 wherein thin coatings 18 of rubber stock are appplied to 'form a tyre fabric The latter is wound with a fabric liner 20 on a roll 19 for subsequent vulcanization in a tyre mould. The rubber stock contains vulcanizing ingredients and 0.64 per cent of resorcinol flakes milled therein. Alternatively the rayon cords are exposed to the vapour of sublimated paraformaldehyde for 21 hours at 100C. In a further example paraformaldehyde is applied by a roll to one side only of a rayon cord layer. a rubber stock containing resorcinol calendered on to each side of the layer, and the assembly vulcanized. The paraformaldehyde is thermally decomposed into gaseous formaldehyde which disperses throughout the assembly to ensure that resorcinol formaldehyde resin is formed over the whole of the rubber-textile interface.

Title: Improvements in rotary coin holder mechanisms
Inventor: CHARLES JOHN ARTHUR
IPC: G07F15/02
Filed: 1955-08-19
Abstract: 832,345. Prepayment meters. UNITED GAS INDUSTRIES Ltd. Aug. 17, 1956 [Aug. 19, 1955], No. 24022/55. Class 27 A rotary coin holder for a prepayment meter for gas, electric or like commodity is operated by a single size or denomination of coin and controls the meter so that initially, until a predetermined number of coins have been deposited, a high rate of charge is made for the commodity in order to collect a neutral or basic charge. The holder has a pair of strikers 1, 2 and a coin platform 3 is provided on the rear or under striker 2 so that initially only the striker 2 is moved down for engagement of its tooth 11 with a quantity wheel governing delivery at the high rate of charge. Each coin insertion and holder rotation is counted by a ratchet wheel 16 that is carried by the striker 2 and is rotated by a pawl 29 pivoted on the striker 1; a locking pawl 17 is provided for the ratchet wheel. The pawl 29 is spring-loaded out of contact with the. ratchet wheel when the striker 2 is moved down by the insertion of a coin but a cam 32 of the spindle of the handle 30 moves the pawl into the path of the ratchet wheel so the latter is advanced one step as the striker 2 returns to inoperative position when the holder has been completely rotated and the coin released. After a predetermined number of coins have been inserted, a recess 23 or cam surface on the ratchet wheel comes opposite a pin 22 on a spring-loaded lever 20 pivoted at 19 on the striker 2 and the lever is allowed to move through a slot 26 in the striker 1, thus locking the two strikers together. On subsequent insertion of coins, both strikers are moved together and the quantity mechanism is operated for delivery at the standard rate of charge. In order that an authorized representative may re-set the mechanism, the hollow bars 34 of the ratchet wheel may be partly cut away as at 35 for cooperation with a key and the key may have a radial pin co-operating with an end stop, such as the pin 8 for the striker 2. An adjustable stop for determining the initial position of the ratchet wheel may be provided on the ratchet wheel or other suitable part. The two strikers may be arranged side-by-side and the driving pawl for the ratchet wheel may be carried by the striker which operates alone during the high-charge period, the ratchet wheel then being on the other striker. The disposition of the ratchet wheel and the strikerlocking lever may be at right angles to the positions illustrated. Specifications 400,636 and 405,302 are referred to.

Title: Improvements relating to electricity meters
IPC: G01R11/36
Filed: 1926-10-01
Abstract: 280,335. Amberton, R., and Barbour, R. H. Oct. 1, 1926. Motor meters; special quantities, registering.- In an electricity meter provided with a torqueproducing element capable of rotating the moving system at a speed independent of the load. this element is excited by shunt coil which magnetizes a relatively saturated iron circuit. The invention is shown applied to an induction motor meter of the kind described in Specification 198,772, in which a disc a is driven by an element A, comprising a shunt coil 2 and series coils 4, at a speed proportional to the load. On the shaft of the disc a is fastened a second disc b driven by an element B, comprising a relatively saturated magnet 6 below the disc b and a keeper 7, above this disc, within which is disposed a copper ring 11 asymmetrical with regard to the shaft. The winding 8 of the element B is connected in series with the shunt winding 2 of the element A. If the voltage of the supply mains 9, 10 increases, an increased current flows through the coils 2, 8, producing a greater increase of flux in the unsaturated magnetic circuit of the element A than in the saturated circuit of the element B. The voltage drop over the coil 8 therefore increases to a less extent than that over the shunt coil 2, thereby tending to keep the torque due to the element B constant. In order to adjust the speed due to the element B independently of the load, the keeper 7 with the copper ring 11 is adjustable laterally. The element A may be arranged to produce an adjustable backward torque independent of the load, as by arranging the series magnet 5 to be adjustably displaced into an asymmetric position. The elements A, B may be mounted side by side or may be combined and arranged to drive the same disc. Alternatively, the coils may be energized by a transformer having a saturated iron circuit and having additional impedance in the circuit of its primary winding connected directly or indirectly across the mains 9, 10. The invention may be applied to a directcurrent meter in which the rotation independent of the load is produced or controlled by a shunt coil. The constant speed independent of the load may be employed for overcoming friction or for registering a fixed charge such as the rent of the meter, or for driving a clock or time recorder. Specification 213,091 also is referred to.

Abstract: 983,995. Drawing. HEAD WRIGHTSON & CO. Ltd. June 27, 1963 [June 27, 1962], No. 24686/62. Heading B3P. In a draw-bench having pneumatic operating means for the draw-hook and work grippers, and means for placing the operating means in connection with a source of air pressure prior to a drawing operation, an air storage tank is mounted on the carriage and there are manually operated means to enable the hook and work-grippers to be motivated by air from the storage tank. The draw-chain engaging hook of the draw carriage is actuated by one or more cylinders 5 and the work grips by cylinders 4. As the carriage approaches the die-stand on the return stroke, a flying needle N engages a bellmouth M and a striker 31 opens a self-closing valve to admit air to a conduit 10 which is connected to a port 23 of a manually-operated self re-setting valve 2. In the normal position of the valve 2 the port 23 communicates with a port 21 connected by a conduit 12 to a fourway connection 13 from which pipes lead to the hook cylinders 5, the work gripper cylinders 4 and via a check valve 24 and a conduit 20 to an air storage tank 1. A conduit 18 leads from the conduit 20 to a port 22 on the valve 2, and when the handle 33 is operated the cylinders 4 and 5 are connected to the tank 1. If the hook or the grips become disengaged during a drawing operation, air from the tank 1 is available to effect re-engagement.
