Title: Improvements relating to brake mechanism
IPC: B60T13/24
Filed: 1930-12-19
Abstract: 368,432. Fluid pressure brakes; valves. CHRISTENSEN, N. A., 1719, Sheridan Road, Cleveland, Ohio, U.S.A. Dec. 19, 1930, No. 38369. [Class 103 (i).] Control valve mechanism for vacuum brakes for motor vehicles, particularly such operated by the suction of the engine comprises a pair of leaf spring valves controlling respectively suction and atmosphere ports. The valves may be operated by "follow-up" mechanism whereby when one or other of them is opened by the pedal &c. in applying or releasing the brakes, it is re-closed by the consequent piston movement to graduate the action. The valve device comprises a casing 37, 38 secured to the casing 16 of the lever mechanism and in which is secured at 37<1>, superposed leaf spring valves 46, 47, controlling respectively a passage 41, leading to the casing 16 thence to the atmosphere or by pipe 45 to the engine crank case and a passage 40 leading to the engine suction pipe. A further passage in the valve casing leads by pipe 14 to the brake cylinder 11. The valve 46 is operated by a plunger 52 connected through a spring 53 to a pin 54 which passes freely through the valve 47 and engages the valve 46. The valve 47 is operated by a plunger 57, 58 connected through a spring 62 with a plunger 59. The lever system for operating these plungers and the brakes comprises a floating lever 24 carried by a pivot 23 on the crank arm 22 of a shaft 18, Fig. 4, connected by the arm 20 to the pedal. A pin 35 on the arm 22 passing through an enlarged hole 36 in the lever 24 limits the relative movement of this lever with respect to the arm. The upper end of the lever 24 engages the valve plunger 52 and the lower end is connected by a link 33 to an arm 28 on a shaft 19 connected to the brakes. The brake piston 12 has a slotted connection with the end of the lever 28. Normally these parts are in the position shown in Fig. 1, the suction and release valves 47, 46 being respectively closed and open. Movement of the pedal causes the arm 22 to swing the lever 24 about its lower pivot thereby at first moving the valve plunger 52 to close the release valve 46, Fig. 5, and then by contact of the head 56 of this plunger with the plunger 57 flexing the valve 47 to connect the cylinder 11 to suction. The consequent movement of the piston 12 turns the arm 28 to apply the brakes and also swings the lever 24 about the pivot 23 so that if the pedal is held the plunger 57 is returned by the spring 60 and the suction valve 47 closes, the valve 46 remaining closed. The valve 47 may be re-opened by further movement of the pedal. The release of the brakes may be similarly graduated by release movement of the pedal. When in the application of the brake, the suction valve 47 has been opened, a direct effort may be applied by the pedal to the brakes through the levers 24, 28 and link 33, the slotted connection between the lever 28 and piston 12 preventing the piston from interfering with this action.

Title: Method and apparatus for destructive hydrogenation
IPC: C10G1/06
Filed: 1928-12-31
Abstract: 326,896. Tate, W. R., Stephenson, H. P., and Imperial Chemical Industries, Ltd. Dec. 31, 1928. Hydrogenation, destructive.-Liquid or pasty carbonaceous materials are destructively hydrogenated by passing them together with hydrogen under high pressure through a heated coil or coils inside a. high pressure vessel. The coil may be heated by gas under high pressure flowing across the coil or flowing through a second coil enveloping the first. A spiral coil 1, Fig. 1, with a heating jacket 7 is arranged within a high-pressure vessel 2, the intervening space being packed with lagging 3. A mixture of oil and hydrogen is supplied to the coil by pipe 6, and is heated by a hot gas, e.g. carbon dioxide or nitrogen, entering the jacket 7 by a pipe 8 and leaving by a pipe 9. The heating gas is preferably under a pressure equal to that of the reaction mixture. The hot reaction mixture is discharged by a pipe 5 into a separating vessel 4, gaseous products passing out by a pipe 12 while sludge is removed by a pipe 11; surplus liquid withdrawn by a pipe 10 is recirculated. In an alternative form, Fig. 3, a space is provided for further reaction in the vapour phase. The reaction materials passing through the spiral 1 are heated by hot gas in a surrounding spiral, and pass into a separating vessel 4, from which liquid and sludge are withdrawn as in the first example. The gaseous products pass over an electric heater 22 and through a catalyst basket 20, escaping finally through a grid 23 and a pipe 21.

Title: Improvements in or relating to conveyors for transporting bulk materials
IPC: B65G17/10
Filed: 1959-11-13
Abstract: 885,828. Endless conveyers. AUER MUHLENWERKE KOMM.-GES. AUF AITKEN, HEINR. Nov. 13, 1959 [Nov. 13, 1958], No. 38598/59. Addition to 854,646. Class 78 (1). The invention of the parent Specification is modified in that the continuous trough is formed by a series of U-shaped elements 11 which are secured by their bases to an endless belt 2 and each of which has a V-shaped projection on its trailing edge and a V-shaped recess in its leading edge, these mating with the projections and recesses of adjacent elements when the belt 2 is in tension but separating therefrom when passing over a discharge wheel. The arrangement is said to render the trough self-cleaning since when the elements separate and pass downwardly over the discharge wheel, material is shed from the recesses and projections. The conveying run is supported on idler rollers and idler rollers may also engage within the trough on the return run. A rotary cleaning brush may replace one of the idler rollers on the return run.

Abstract: 1,088,451. Stiffening shoes. KAUMAGRAPH CO. Sept. 23, 1964 [Sept. 25, 1963], No. 38765/64. Heading A3B. [Also in Division B6] The toe portion of a fabric shoe upper is stiffened by impregnating that portion with a thermoplastic substance from a transfer sheet by heat and pressure. The thermoplastic substance 10 is applied to carrier sheet 12 as shown, fabric shoe cut-outs 14 are superimposed over the patterns, and the combination is fed through pressure roller 16 and heat roller 18 which melts the thermoplastic. In the example shown the absorbed stiffened material becomes planar with the undersurface of the upper blanks, but if the pattern 10 is applied to the top surface of the upper it functions as a decoration or identification means as well as a stiffener. The thermoplastic may comprise polyethylene wax, or a terpine resin, and to increase the elasticity rubber may ,be mixed therewith. Examples of suitable materials are (1) polyterpine resin, polyethylene, and a filler with or without a dye, and (2) depolymerised rubber, paraffin wax, zinc oxide, sulphur accelerators and a filler.

Title: Improvements in or relating to playback of recorded video signals
IPC: G11B20/02
Filed: 1969-08-06
Abstract: 1,270,849. Playback of recorded video signals. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 Aug., 1969 [9 Aug., 1968], No. 39414/69. Heading H4F. A circuit is described for replacing line synchronizing pulses missing from a video signal played back from a recording tape due to the manner in which the tape is wound helically around a drum containing a rotating playback transducer. The circuit includes a phase comparator circuit 4 to which are applied pulses from a sawtooth generator 2 and line sync pulses 6 from the tape, the output at 8 providing an indication of the relative phase of the two pulse trains. This output is applied firstly, via a smoother 9, to the generator 2 to synchronize its frequency to the line sync rate, secondly to a clamping circuit 12 and thirdly to one input 15 of a switch 16. The second input 13 of the clamping circuit 12 receives only the first line sync pulse 14 from each transverse track of the tape, and the output applied to the second input 17 of the switch 16 is clamped for the entire interval between the commencement of playback from successive tracks to a D.C. level indicative of the relative phase of this first line sync pulse. A pulse 18, e.g. derived from the frame flyback pulse or from a pulse associated with a part of the playback apparatus, causes the switch 16 to change from input 15 to input 17 only during the period when the line sync pulses are missing, and the output of switch 16 is compared in a further comparator circuit 20 with the sawtooth output of the generator 2 so as to provide a pulse train 24 in which the missing line sync pulses are replaced. In a modification the sawtooth generator (32), Fig. 3 (not shown), is the line oscillator of the display circuit and the switch (46) is connected thereto via a tuning circuit (56). The smoother (39) for the output of the phase comparator (34) now lies between the comparator (34) and one input (45) of the switch (46). This modification dispenses with the comparator 20 of Fig. 1.

Abstract: 1,113,875. Sampling gases. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 12, 1966 [Sept. 21, 1965 (2)], No.40720/66. Heading G1B. In a method of sampling air at high altitude, the air or a component therein is absorbed by a molecular sieve from which it can be desorbed for analysis when the apparatus has been recovered on the ground. In Fig. 2 molecular sieving e.g. a synthetic zeolite is contained inside a double torus 15 in a vessel containing liquid nitrogen and to which atmospheric air at the desired high altitude is admitted through an inlet 9 and valve 11, the air passing first through a coil 13 which cools the air to the temperature of the nitrogen. A heat insulation element 5 surrounds the nitrogen containing vessel. Nitrogen gas circulates within a coiled pipe 29 which may be black to aid heating of the nitrogen gas by solar radiation, and this gas leaves by way of a nozzle 27 discharging through a cone 25, the action of which draws the sample air into the double torus 15 and through an exit pipe 17. The double torus 15 contains molecular sieving to absorb one component of the sample air, e.g. krypton, and the remaining air then leaves through the pipe 17 by way of a valve 19 and is discharged into the cone 25. The valves 11, 19 may be controlled manometrically or by use of a timing device 49. An expansion bladder 41 is provided to prevent over pressures being developed after closure of the valves 11, 19 in the event of desorption of the molecular sieve. After the apparatus has been recovered on the ground an electric heater 51 is energized to desorb the collected sample, the temperature of the molecular sieve being monitored by thermocouples 53, 55. In an alternative apparatus the molecular sieve is arranged to absorb the complete air sample, the sieving being contained in a vessel cooled in liquid nitrogen and to which the sample atmosphere is admitted for a predetermined period of time.
