Title: Vehicle Warning System
Inventor: ACKLAND ANTHONY GUY
IPC: B60Q1/44
Filed: 1966-01-27
Abstract: 1,163,401. Road traffic signals on vehicles. A. G. ACLAND. 24 Jan., 1967 [27 Jan., 1966], No. 3729/66. Heading G4Q. In a vehicle, having at least one rear warning lamp L energized by a switch T operated by a member of the linkage between the accelerator pedal and the engine, a pair of contacts connected in series with the ignition switch I and operating switch T are closed after a delay time from operating the switch T. When the ignition switch I is closed and the accelerator pedal is released contact T is closed so as to energize a bimetallic flasher F which operates to complete the rear warning lamp circuit after a predetermined adjustable delay and then flash the lamp L. The delay time which may be, e.g. 2 seconds, allows the driver to change gear without operating the rear warning lamps L. If the accelerator is released for the set delay time then the rear warning lamps L flash to warn following motorists that the preceding car may be about to apply its brakes. At night or in fog when driving with dipped headlights by closing side and headlight switches S and H and positioning switch A for dipped beam filaments D, the rear warning lights are lit immediately the accelerator is released so that the delay action and flasher become inoperative. The rear warning lamps L may be placed behind transparent amber plastic or glass lenses incorporating triangular marks. The rate of flashing may be the same as or different from that of the direction indicators. The accelerator switch may be a snap action microswitch completely enclosed so that any sparks produced cannot ignite any petrol or other vapour and may be operated by a linkage of a carburetter or a member of the fuel injection equipment of a diesel engine. The rectifiers Z1 and Z2 may be provided with head sinks. The delay in switching the warning lamps L on when the accelerator has been released may be obtained by a pneumatic or hydraulic dashpot controlling the electric contacts. A tell-tale lamp W, which may be mounted on the dash-board or on the boss of the steering wheel, may either flash at a rate different from normal or not flash at all if any of the warning lamps L become open or short circuit. Emergency signalling.-In the case of an accident or puncture an extra switch, which can operate electrical circuits other than the ignition system, e.g. parking lights, may be connected in parallel with the ignition switch I so as to permit the warning lamps to be energized.

Title: Improvements in and relating to brake apparatus for railway vehicles and the like
IPC: B60T15/30
Filed: 1919-02-18
Abstract: 147,246. Cross, J. W., and British Air Brake Co. Feb. 18, 1919. Fluid-pressure.-An accelerating valve for compressed-air brakes, which as regards its action is independent of the triple valve, vents the trainpipe to the brake cylinder in emergency applications and to a limited extent also in service application. The casing 7 of the accelerator valve mechanism may be attached to the casing 1 of the triple valve, which, as shown, is of the kind described in Specification 134,294. The accelerator-valve mechanism comprises a piston 9, the rod 9<a> of which carries a valve 11 controlling communication of the train-pipe by way of the passage 2 and chamber 10 with the brake cylinder by way of the non-return valve 13 and passages 36, 4. The piston 9 works in a chamber 8 the upper part of which is in constant communication with the train-pipe by a passage 34. When the valve 11 is in the closed position, air can feed into the lower part of the chamber 8 from the upper part by a groove 24. A spring 43 closes the valve 11 when the pressures above and below the piston are equalized. When the train-pipe pressure is reduced for a service application of the brakes, the piston 9 rises as far as a spring stop 25b and unseats the valve 11, but the movement is insufficient to withdraw the collar 17 on the valve stem from the bush 19 so that the venting of the train-pipe takes place through the restricted annular passage around this collar. Further, in this position of the piston 9 a passage 23 in the piston-rod connects the chambers 8 and 10 so that, although the groove 24 is closed, the pressures above and below the piston rapidly equalize and the valve 11 is re-closed. An emergency reduction of train-pipe pressure is sufficient to cause the piston to overcome the spring stop 25<b> and, in this position, the collar 17 of the valve 11 is withdrawn from the bush 19 and the lower end of the passage 23 moves into the bush 22, so that the valve 11 is kept off its seat for a time sufficient to permit the pressure in the trainpipe to equalize with that in the brake cylinder. The brake cylinder is supplied at the same time from the auxiliary reservoir by the action of the triple valve. The chamber 6 of the triple valve is in communication with the chamber 10, and thence with the train-pipe, through apertures 38 in a plate 39. The passages 2 and 36 are continued between the casings 1 and 7 by short pieces of tube 32, 37.

IPC: F16H61/14
Filed: 1969-01-24
Abstract: 1,199,713. Clutch combinations. FORD MOTOR CO. Ltd. 24 Jan., 1969 [29 Feb., 1968], No. 4075/69. Headings F2C, F2D and F2U. A hydrodynamic torque converter lock-up clutch disc 68 is connected to the torque converter turbine 40 by a plurality of radially disposed tension springs 74 which prevent the transmission of engine vibration to the torque converter output shaft 64. The clutch disc 68 carries a friction facing 70 engageable with a driving casing 18 fast with the torque converter turbine 16. During operation a pump 58 driven by the impeller 16 through a sleeve 20 supplies pressure oil to the torque converter working circuit through a duct 76 and a space between the clutch disc 68 and casing 18. The pressure in the space between the clutch disc 68 and casing 18 disengages the clutch 70. Oil leaving the torque converter returns through a space between the sleeve 20 and a reactor sleeve 54. To engage the clutch 70 the direction of oil flow is reversed whereupon the pressure in the working circuit engages the clutch 70. The torque converter output shaft 64 drives the input element of a change speed gear (Fig. 2, not shown) which is similar to that described in Specification 1,100,813.

Title: A process for the simultaneous separation and thermic treatment of mixtures of fluids and granular or other substances
IPC: B01D47/16
Filed: 1928-02-09
Abstract: 285,046. Schmidt, P. Feb. 9, 1927, [Convention date]. Gas cleaners.-A process for the simultaneous dissociation and the thermic treatment of mixtures of fluids and granular materials consists in moving the mixture between two surfaces having relative parallel, and preferably, rotary movement. According to one application of the process a gaseous current carrying solid particles to be dried &c. is forced into the duct 1 and distributed by a propeller 3 into the narrow space between a rotary plate 4 and a fixed gas-heated plate 9 so that a general radial velocity is imparted to the gas, varying in magnitude from a maximum at the surface of the rotary plate to a minimum at that of the hot plate, while the particles also have a motion towards the hot plate. The particles collect below the hot plate while the gas, which may be air, passes away through the duct 11. In another application for precipitating salts from solution, the solution flows upwardly through a duct into the space between a water-cooled rotary chamber 4<1>, Fig. 3, and a fixed plate 2<1>, the precipitated crystals connecting in the space beneath the fixed plate and the solvent flowing away through the duct above the rotary plate. Specification 282,840 is referred to.

Abstract: Resinous products are obtained by reacting a silicon compound containing at least three alkoxy groups or two alkoxy groups and at least one halogen attached to silicon with a dialkyl sulphate and sodium in amounts calculated to produce the desired polyalkoxy-alkylsilane, and then hydrolysing with an aqueous medium. In examples: (1) and (2) tetramethyl orthosilicate, sodium and diethyl sulphate are reacted in toluene with or without the addition of silicon tetrachloride, and the resulting ethyl-methoxy silanes are hydrolysed to yield a liquid ethyl silicone.ALSO:Alkyl-substituted silicon compounds are prepared by reacting a silicon compound containing at least two alkoxy groups attached to silicon with a dialkyl sulphate and metallic sodium, e.g. by the application of heat and employing an inert solvent.  The silicon compound to be reacted may also contain halogen, alkyl or aryl groups attached to silicon and may be a polyalkoxysilane. Suitable silicon compounds for the process of the invention are tetramethyl orthosilicate, trimethoxy chlorsilane, phenyl trimethoxy silane and silicon compounds containing at least three alkoxy groups or two alkoxy groups and at least one halogen atom attached to silicon.  The amount of dialkyl sulphate employed is an amount having at least as many alkyl groups as there are alkoxy groups and/or halogen atoms in the silicon compound to be replaced by alkyl groups, together with sufficient metallic sodium, both to displace from the dialkyl sulphate the requisite number of alkyl groups and to displace from the silicon compound to be reacted the alkoxy and/or halogen atoms to be replaced by said alkyl groups.  The product obtained may be a mixture of silicon compounds having an average composition corresponding to the composition of the desired product.  A silicon compound containing at least one halogen atom may be present in the reaction mixture, e.g. silicon tetrachloride, silicon oxychloride, trimethoxy chlorsilane or a methyl chlorsilane.  Resinous products are obtained by reacting a silicon compound containing at least three alkoxy groups or two alkoxy groups and at least one halogen attached to silicon with a dialkyl sulphate and sodium in amounts calculated to produce the desired polyalkoxy-alkylsilane, and then hydrolysing with an aqueous medium.  In examples: (1) and (2) tetramethyl orthosilicate, sodium and diethyl sulphate are reacted in toluene with or without the addition of silicon tetrachloride, and the resulting ethyl-methoxy silanes are hydrolysed to yield a liquid ethyl silicone; (3) tetramethyl orthosilicate, dimethyl sulphate, sodium and silicon tetrachloride are reacted in tetrahydronaphthalene and methyl methoxy silones separated by fractionation.
