Title: Web accumulators
IPC: B65H19/14
Filed: 1971-04-13
Abstract: 1397071 Feeding webs MASSON SCOTT THRISSELL ENG Ltd 13 July 1972 [13 April 1971] 9304/71 Heading B8R A web accumulator, e.g. in web splicing apparatus as described in U.K. Specification 1,199,922, comprises a first carriage C2 movable by drive means relative to a second carriage C1, each carriage having a plurality of rollers 47, 48, 49, 50 and 30, 31, 32, 33, 34 arranged in V formation, to provide a web path around all the rollers, with alternate rollers in the path being rollers of the first carriage and the intervening rollers being rollers of the second carriage. The drive means comprises a motor 62, the drive of which is transmitted through a gear-box 65, hollow shaft 69 and slipping clutch 68 to a chain 59 attached to the carriage C2 which runs on rollers in vertical rails. The torque required to slip the clutch is controlled by the pressure of air supplied to the clutch through the shaft 69, the pressure being adjusted by regulators (83), (88), Fig. 6 (not shown) connected in parallel. In operation, when a splice is desired to be made the pneumatic/electrical circuit of Fig. 6 is manually triggered. Firstly, a web supply reel (2), Fig. 1 (not shown), is pneumatically braked thereby increasing the tension in the web, which is continually fed to a web consuming device. The increased tension in the running web pulls the carriage C2 downwards causing the clutch to slip. At the same time a striker 104 on the carriage C2 actuates an electric switch which starts the motor 62, the latter being ineffective, however, due to the slipping clutch. The striker 104 also actuates a pneumatic valve which initiates the splicing operation. This may be inititated before the reel 2 has been brought to a standstill, web clamps being used to hold the web stationary in the splicing station. After splicing, the reel brakes and web clamps are released, the carriage C2 stops descending, and the clutch stops slipping as the replacement reel (6) accelerates to web feed speed. When clutch slip stops, the motor 62 is effective to raise the carriage C2 and replenish the web in the accumulator. Tension in the running web is controlled by a pneumatically adjustable roller (7).

Patent GB-610141-A (GB)
Title: Improvements in controls for the brake system of a tractor trailer vehicle
IPC: B60T13/58
Filed: 1946-03-28
Abstract: 610,141. Fluid-pressure and electromagnetic brakes. WARNER ELECTRIC BRAKE MANUFACTURING CO. March 28, 1946, No. 9654. Convention date, April 16, 1945. [Class 103 (i)] In a tractor-trailer brake, including a fluid - pressure - actuated tractor brake system comprising a chamber receiving the brake-applying pressure and having a wall, e.g. a piston or diaphragm, movable away from a predetermined limit position when the brakes are applied, and an electromagnetically-actuated trailer brake system having a circuit which is controlled by a rheostat provided with a movable contact actuated by the movable wall and effective first to close the circuit and then decrease its resistance; the movable wall is positively connected to the movable contact and is associated with spring means which are inoperative during the initial movement of the wall but then become effective to offer increasing resistance to further movement of the wall. As shown in Fig. 1, a pedal-operated hydraulic master cylinder 10 on the tractor is connected by pipes 8 and 9 to the tractor brakes 7 and by a pipe 3 to a control device 5 in the circuit 30 of a battery 15 supplying the trailer brakes 12. The device 5, Figs. 2 and 3, comprises a rheostat 16 having a plurality of spring contacts 28 connected through resistances 29 to the ungrounded terminals of the brake windings 13, and a movable contact 26 connected to the ungrounded terminal of the battery 15 and carried by an arm 24 pivoted at 25. The arm is linked to an arm 20 acted on by a light torsion spring 22 and secured to an actuating shaft 19, the other end of which carries an arm 44 having a bifurcated end embracing a pin 46 on an axially-movable rod 36. The end of the rod is formed as a piston 35 movable in a cylinder 33 to which the pipe 3 is connected, and the other end 37 is guided in an axially-adjustable screwed plug 38. A strong spring 50 is interposed between a seating 51 on the plug and a flange 53 on a bushing 54 carried by the rod, the extended length of the spring being such that clearance exists between its end 52 and the flange 53 when the rod is in its limit position determined by a shoulder 48. The rod is thus held in its limit position with the contact 26 open solely by the light spring 22, and this ensures that a light pressure on the master cylinder pedal is sufficient to close the circuit and effect application of the brakes on the trailer before those on the tractor, thus preventing " jack-knifing ". After the spring clearance has been taken up, the energization of the trailer brakes is increased proportionally as pressure is built up in the chamber 33 by the application of the tractor brakes, the rolationship between the braking efforts applied on the tractor and trailer being determined by the strength of the spring 50 which is adjustable by the plug 38. The invention may be applied to tractor brakes activated by compressed air or vacuum, in which case the piston 35 is replaced by a sealed diaphragm.

Title: Process of recovering sulphur from pyrite fines
IPC: F27B21/06
Filed: 1948-04-08
Abstract: <PICT:0651297/III/1> Sulphur and sulphur dioxide are recovered from pyrites fines by nodulizing the fines, placing a mass of the nodules on a gas previous support in a bed of substantial thickness, e.g. 1 foot, without relative movement of the particles of the mass, igniting the pyrites fines on the surface and propagating the ignition in the same direction as the direction of flow of air to and through the mass, cooling the effluent gases to condense the sulphur, mixing a part of the remaining gases with a predetermined amount of incoming air and recycling the mixed gases through the burning mass to control the reaction.  Dry nodulized fines 1/8 -\ba1/4 inch diameter are charged on to grate 2 in cylinder 1 and ignited on the surface by applying a gas flame while drawing air through the mass. Effluent gases pass through chamber 3, condenser tubes 7, 8 connected serially by header 9, chamber 10 and cylindrical space 11; the sulphur is condensed and may be removed by drain 12.  The condensing parts of the apparatus are surrounded by temperature controlling oil bath 13 whose temperature may be adjusted by cooling coil 14 and the condensation may be assisted by the action of wire electrode 18 and ground lead 21.  The gases from space 11 are withdrawn through passage 22, which may be packed with steel wool to remove any remaining sulphur, by motor-driven fan 23, and one portion may be withdrawn at 25 for the recovery of sulphur dioxide, while the remainder is recycled, with or without additional inert gas, through metering orifice 28 to cylinder 1; air being added at 29. Manometer connections 4, 31, 32, 34 are provided to facilitate control of the gaseous feed.  The residue in cylinder 1 is ferroso-ferric oxide and/or iron sulphide.  An apparatus for continuous operation is also described.

Title: Improvements in or relating to drying oils
IPC: C09F5/06
Filed: 1943-06-21
Abstract: A drying oil is produced by heating castor oil with a monocarboxylic acid having double bonds in the 2 and 4 positions. Alternatively, the free fatty acid corresponding to castor oil, either alone or mixed with castor oil, may be heated with the monocarboxylic acid and the product esterified with a polyhydric alcohol such as glycerol. Monocarboxylic acids mentioned are sorbic, octatrien-2,4,6-oic, 4-methylheptadien-2, 4-oic, 5-cyclohexyl-pentadien-2,4-oic and 7-phenyl-heptatrien-2,4,6-oic acids, and it is believed that the monocarboxylic acid esterifies the tri-ricinolien of the castor oil. Drying oils thus produced from castor oil may form the whole or part of the oil-component in oil-modified synthetic resins, such as glyceryl phthalate alkyd resins and resins derived from formaldehyde and phenols, and may also be used in the production of varnishes from natural resins. The Specification includes details of the synthesis of the monocarboxylic acids listed above.
