IPC: B61C9/48
Filed: 1932-11-05
Abstract: 409,045. Electric tramcars; mounting motors. E.M.B. CO., Ltd., and CADBURY, G. N., Moor Street, West Bromwich. Nov. 5, 1932, No. 31206. [Class 79 (iii).] In an electric tramway or railway vehicle of the kind in which the driven axle d is rotated by suitable gearing, b, c from a motor mounted in close proximity thereto, the axle d is supported directly in bearings near one end of the motor casing a, while the opposite end of the latter is pivoted to the truck frame h through the medium of an horizontal pivot shaft e. The truck frame is supported from the axleboxes l, which float within gaps or recesses i in the truck frame, by swing links k connected to the ends of leaf springs j. Preferably, in order to make provision for a difference in level during running between the two ends of the axle, the casing a is not mounted directly on the shaft e, but is resiliently associated therewith by means of interposed springs n. Specifications 27334/11 and 218,767, [both in Class 79 (iii)], are referred to.

Patent GB-1111422-A (GB)
Title: Process for the separation of petroleum distillation residues or other higher boiling hydrocarbon materials
IPC: B01D11/02
Filed: 1965-07-22
Abstract: The separation of high boiling hydrocarbons, e.g. to remove asphalt or vanadium compounds from petroleum residues, is effected by treating with a gas, having a critical temperature of 90-250 DEG  C., at above its critical temperature and pressure whereby part of the starting material is taken up into the gas phase (e.g. leaving <PICT:1111422/C4-C5/1> asphalt or vanadium compounds), separating the charged gas phase and recovering charged materials largely by reduction of pressure to below the critical pressure, cooling the gas which is discharged until it liquefies, recompressing the liquid so obtained and reheating to supercritical conditions and recycling to the separation step.  In a preferred embodiment liquid starting material in line 2 is mixed with "supercritical" propane in line 3. Mixing is assisted by filling materials in the tube and subsequent quiescence by vertical baffles. Gas is separated from liquid in the central spherical section of apparatus 1 and after cooling in heat exchanger 8 pressure is reduced in valve 9 while heating in bath 18 so that separated materials are obtained as a liquid and recovered as product through valve 11.  The other constituents of the starting material are recovered through valve 6.  The reduction of pressure is preferably such that the gaseous propane can still be liquefied by cooling to room temperature and this is done in heat exchanger 14. The liquid is recompressed and heated to "supercritical" conditions in pump 15 and heaters 14 and 8.  Additional cooling and heating necessary are supplied by further heat exchangers with external supplies.

Abstract: 284,062. Gowan, S., and Metropolitan- Vickers Electrical Co., Ltd. Dec. 15, 1926. Dashpots of the kind in which ordinary forces are opposed by retarding forces following a predetermined law while abnormally large forces are opposed by a much greater retarding force, comprise a cylinder and piston arrangement haying a byep a s s through an auxiliary cylinder with a piston adapted to close the normal regulating valve when the pressure exceeds a certain value. A one way valve 5 is provided to close the ports 7 in the piston 1 and a bye-pass 8, controlled by an adjustable plug 9, connects the ends of the cylinder. An additional bye-pass 10, 18 is provided containing a piston 12 with a central passage 13 having a valve 14 at its upper end allowing flow in one direction. When the pressure below the main piston 1 exceeds a certain amount, the piston 12 rises against the resistance of the spring 19 until the ball valve 14 abuts against the fixed stop 17 and closes the passage 13.

[Also in Groups XL(a) and XL(b)] The vacuum above the aperture 80 is maintained, although in communication with the atmosphere below the aperture 81, by means of a rotating drum 82 which periodically puts radial bores 86 in line with apertures 80, 81 to allow passage of a beam of charged particles right through the system (see Group XL(a)), but rotates at such speed that air penetrating into a bore 86 when opposite aperture 81 does not have time to pass into an inner fixed drum 83. Air within the drum housing, however, is withdrawn by pumps connected to spaces 91, 96 and 92, 97. Air at relatively high pressure is withdrawn from spaces 91 96, and air at relatively low pressure from spaces 92, 97. To help in preventing the ingress of air through the aperture 81, sound oscillations may be set up at point 101 to develop a negative pressure there, or jets of compressed air may be injected into the aperture 81 in a downward direction from lateral channels in the wall 90.

A timepiece is fitted optionally with a central or an eccentric seconds hand in a torque train between the barrel and the excapement. Spring barrel 1 drives an eccentrically disposed minute wheel 3 which drives a pinion 4 fast with a first intermediate wheel 5. This wheel 5 meshes with a central seconds pinion 6 which in turn meshes with a second intermediate wheel 9 loose on the arbor of pinion and wheel 4, 5. The second intermediate wheel 9 drives an eccentrically disposed seconds arbor 10, a wheel 11 of which drives the excapement 12. If an eccentric seconds hand only is to be fitted, on arbor 10, the central seconds pinion 6 and the loose intermediate wheel 9 are omitted, a single intermediate wheel 9<SP>1</SP>, fast with the pinion 4, then driving directly on to the eccentric seconds hand pinion on arbor 10. The dial train, comprising the-cannon pinion 13, hour wheel 14 and change gear 15, is driven from the minute arbor 2 through a pinion 16, there being a frictional connection between the minute arbor 2 and pinion 16. The arbors of all the wheels connected with the seconds hands are situated as shown in Fig. 2 substantially all on one side of a diameter so that the balance wheel is left clear of obstruction and the balance spring cannot accidentally hook on to one of these wheels, also, the overall depth between the plates 7, 8 is determined solely by the barrel 1 and the minute wheel 3.

Abstract: 1,007,270. Embossing surfaces. MODERN ENGRAVING & MACHINE CO. Aug. 11, 1964, No. 32596/64. Heading B6C and B6J. A metal roller for embossing material with a stucco pattern is formed by manually applying, e.g. by means of a sponge, a resist to the metal in random patches 14 and etching the exposed metal areas 20. This operation may be repeated two or three times, if desired, the resist subsequently being washed off. Before the etching step, parts 22 of the patches may be removed by means of a sharp tool 16. Any sharp edges may be removed by etching the cylinder over all its surface. If it is desired to reduce the depth of the etched recesses, the cylinder may be sprayed with a resist as it is rotated, so that the resist tends to fill the recesses, and rotating the cylinder in an etching bath. After this operation, sharp edges may be removed by overall etching or by means of a rotary wire brush. Surface hardening of the roller may be effected by flames issuing from a multi-apertured pipe. A mating cylinder may be formed by uniformly coating a metal cylinder with resist, rotating the cylinder in contact with the first cylinder by gears so as to remove the resist from the mating cylinder where the raised parts of the first cylinder engage it, and then etching the mating cylinder.
