Title: A process and apparatus for recovering the benzol contained in coal gas
IPC: C10K1/04
Filed: 1922-09-19
Abstract: 210,114. Aguillon, J. E. Sept. 19, 1922. Cooling gases, tubular apparatus for; cooling gases by combination of direct and indirect methods; rime, removing. - Coal gas is passed over tubular or other surfaces cooled to a temperature of about -50‹ C. by the evaporation of liquefied carbonic acid, the benzol being deposited on the surfaces in the form of snow and removed therefrom by mechanically-operated scrapers. The gas to be treated is first passed through a cooler or condenser 1, where it is cooled by direct contact with a liquid medium or by cold surfaces to a temperature of about 0‹ C. to separate the greater part of the water and naphthalene. It then flows through an interchanger 2 to the final cooler, which is fitted with pipes or the like 3 through which carbonic acid from a refrigerating machine is evaporated. The coils may be arranged as concentric cylinders connected in series by bends at the top, the scrapers 4 being supported by a cross-piece 9 at the bottom of a rotating shaft 8. The solid benzol collects in the bottom 5 of this cooler, and may there be melted by slight warming before removal. The gas freed from benzol passes into the upper chamber 6 of the interohanger 2, and there serves to cool a descending stream of calcium chloride brine, which is used in the lower chamber 7 to cool the gas passing to the final cooler. The brine may be filtered to separate the tar and naphthalene accumulated in the chamber 7, and is pumped to the upper chamber 6. The cold surfaces in the final cooler may be movable, and baffles may be fitted to the movable parts to direct the gas on to the surfaces.

Title: Improvements in or relating to ceramic dielectric materials
IPC: C04B35/468
Filed: 1960-07-21
Abstract: 912,307. Semi-conductor devices; capacitors. SIEMENS & HALSKE A.G. July 21, 1960 [July 21, 1959], No. 25442/60. Class 37. A chemically-reduced sintered ceramic material has a grain size less than 5 Ám. The Specification explains that for a sintered ferro-electric material such as barium titanate the dielectric constant of the material is increased if the grain size is maintained small. Accordingly the reduction process is carried out in a temperature range the upper limit of which is approximately 30‹ C. below the sintering temperature of the non-conductive starting body of barium titanate. The temperature is kept as close as possible to the upper limit for as short a time as possible to prevent the grains from growing together. The thickness of the barrier layer is also increased but the reduction of capacity is more than offset by the increase in dielectric constant and at the same time the breakdown voltage is increased. The Figure shows a construction of capacitor in which a disc of barium titanate 1 made " N "-conductive by reduction in the manner described has fired to it silver coatings 2, 3 in an oxygen atmosphere so that the oxygen content of the titanate is greater than in the interior, producing PN junctions on both sides of the device so as to block an applied A.C. in both directions.

Title: Improvements in or relating to machine tools
Inventor: AMOS ROBERT WALTER JAMES
IPC: B24C3/32
Filed: 1964-06-19
Abstract: 1,007,211. Blasting; driving and transmission devices. STANDARD TELEPHONES & CABLES Ltd. June 19, 1964, No. 25491/64. Heading B3B and B3D. A machine tool includes a rotatable workpiece-supporting turntable member driven by a drive wheel member, a force of one of said members being maintained in direct frictional contact with the edge of the other of said members, a machining tool traversable along a path across the workpiece-supporting face of said turntable and means for varying the edge-face contact distance between said members as measured radially from the axis of rotation of the face contacted member in co-ordination with the traverse of said tool. A workpiece 6 stuck to a rotary table 5 is machined by an abrasive blast from a nozzle 12 carried by a housing 10 carrying an electric motor 9 which, through gearing 21, 20 drives a lead screw 19 to traverse the housing 10 and nozzle 12. The motor 9 also drives a friction wheel 7 driving the table 5 so that the angular velocity of the table is automatically varied during the traverse to maintain constant the linear speed of the table beneath the nozzle 12. The lead screw may be driven by a separate motor. The shaft of the table 5 may be journalled in a support above the table, leaving the bottom face of the table clear for the wheel 7. Alternatively, the arrangement shown in Fig. 2 may be used. The nozzle 12 and wheel 7 need not be at the same radial distance. The nozzle may be vertically and angularly adjustable. When containing a workpiece the speed of the electric motor rotating the drive wheel 7 is varied during traverse of the nozzle 12 so that over a region where a deeper cut is required, the linear speed of the workpiece past the nozzle 12 is reduced by reducing the speed of the motor.

Filed: 1920-09-04
Abstract: 170,468. Deutsche Koks-Gas-Ges., and Tenckhoff, R. Sept. 4, 1920. Producers.-In a water-gas producer of the kind in which steam is alternately introduced at the top and bottom of the fuel bed, the air-supply pipe, gas discharging pipes, steam-pipes, and damper are controlled by movement of a single lever. The air-supply pipe c, the gas-pipes d, e, and the gas-outlet pipe f terminate in a casing l having a plug valve m operated by a lever n, which is also attached to a controlling-disc having three toothed segments u, v, w engaging valves s, t of the steam-pipes k, i. When the lever n is depressed to the position shown in Fig. 4, a lever q having a pin r engaging with the lever n is depressed, and by means of a rope attachment p the damper o is raised; at the same time the plug m is turned to pass the air from the pipe c to the pipe e at the bottom of the producer, and the fuel is blasted up. By turning the lever n to the position shown in Fig. 5, the lever q is released, allowing the damper to fall, the plug m gives communication between the gas outlet f and the bottom of the producer, and the toothed segment u on the disc has opened the steam-valve s supplying steam to the top of the producer by the pipe i. A further movement of the lever n to the left reverses the flow of steam through the producer. In a modification, the steam-valves may be operated by a cam and roller mechanism.

Title: Improvements in and relating to sliding doors for vehicles
IPC: B60J5/06
Filed: 1936-09-22
Abstract: 482,199. Sliding-door holders and fastenings. SUNSALOON BODIES, Ltd., and PEARSON, D. A. Sept. 22, 1936, No. 25707. [Class 44] The sliding door of a vehicle is prevented from closing unintentionally by acceleration of the vehicle by wedging means which always allow free opening movement of the door and free closure only when the door is moved by the handle provided. Figs. 1, 3 show a door 10 hung by plate 11 and rollers 13 which run on the lower flange of a rail 14, the rail being of channel section with upper and lower horizontal flanges and intermediate vertical web. A carriage 12 moving with the door carries the wedge device comprising a pair of oppositely directed wedges 15, 16 between which a cage 19 having anti-friction rollers 20 may be provided. The upper wedge 15 is capable of vertical movement between stop blocks 17, 18 on carriage 12 which prevent endlong movement. The lower wedge 16 besides having limited vertical movement has limited endlong movement between stops 17, 18 and is urged by a light spring 29 so that the wedges normally bear lightly against the rail flanges. The cage 19 may also be acted on by a light spring 30. Wedge 16 carries a friction plate 26. Owing to the normal frictional engagement of plate 26 with the rail flange, wedge 16 lags behind wedge 15 when the door is moved and, as shown, if the door moves towards the right or closing position, wedges 15, 16 operate to grip the rail flanges more tightly and stop said movement. Reverse movement of the door releases the wedges to allow free opening. Closing the door by the handle (not shown), depresses a rod 22 and operates one arm 27 of a pivoted lever so that its other arm 21 engages a bolt 23 carried by wedge 16 and projecting through a slot 28 in carriage 12, so that wedge 16 is moved to release position. Fig. 6 shows a modification using a pivoted eccentric cam 32 biassed to contact with the upper rail flange by a light spring 49 or by counterweight which may act as a pendulum. The door is held closed by a pawl-like catch 41 engaging teeth 42. The operating handle 39 pivoted at 38 has adjustable tappets 35, 46 engaging arms 34, 45 on cam and catch respectively. Cam 32 is released by tappet 35 on closing the door by the handle, but otherwise prevents closure. Opening the door by the handle causes tappet 46 initially to release catch 41.
