Abstract: 1,079,940. Rolling tubes. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I PROEKTNOKONSTRUKTORSKY INSTITUTE METALLURGICHES KOGO MASHINOSTROENIA. Dec. 9, 1964, No. 50045/64. Heading B3M. [Also in Division H2] Riffled tubing 3 is formed by rotary head 1 with grooved rolls 2, the head constituting a planet carrier driven by motor 6 through gears 7, 8, whilst the rolls are coupled to planetwheels 10 riding on sun-wheel 11 which is driven by motor 14 through gears 12, 13. To prevent twisting and rotation of the stock during the rolling process, the motor torques are in a fixed relationship and oppositely directed. The motor 14 is energized through a two-stage magnetic amplifier having coils which receive respectively a reference signal, a negative feedback signal representing the armature voltage, a positive feedback signal representing the armature current, and a stabilizing signal responsive to the rate of change of armature voltage. The motor 6 is energized in a similar manner, the relationship between the torques being maintained by developing a voltage proportional to the armature current of the motor 14 and subtracting a reference voltage. The difference signal is divided and then applied to a coil forming part of a magnetic amplifier which feeds the motor 6. This amplifier has another coil which is energized similarly but in accordance with the armature current of the motor 6 whose speed is varied until the ampere-turns of the two coils are balanced. The reference voltages are adjusted to afford zero difference signals under no-load conditions, the voltage dividers being adjusted under loading conditions so that the tube does not rotate during rolling. The head 1 is coupled to a pulse counter 39 which supplies a signal for separating the rolls 2 in response to the passage of a preset length of riffled tubing. An auxiliary epicyclic differential may be placed between the wheels 8 and 11. In another embodiment, the drive is effected by a single motor associated with an auxiliary epicyclic differential driving the components 1, 2, through separate gear trains. The tubing may be riffled whilst passing from an uncoiler to a coiler.

Abstract: 1,165,907. Thermal cracking. STONE & WEBSTER ENG. CORP. 11 Nov., 1966 [13 June, 1966], No. 50700/66. Heading C5E. Olefins, particularly ethylene, are produced by thermal cracking of a hydrocarbon feed by indirect heating in a tubular reaction zone under the following conditions: steam: hydrocarbon weight ratio: 0À1-2À0  residence time: 0À1-0À5 seconds gas effluent outlet temperature: at least 1500‹ F. outlet gas hydrocarbon partial pressure: 5-20 p.s.i.a. pressure drop across reaction zone: at most 30 p.s.i. and rapidly cooling the effluent gases to a temperature at which cracking ceases. The process may use a furnace comprising a convection preheat zone and a radiant cracking zone, the tubes in the cracking zone being relatively short, of small diameter and of low pressure drop design. The tubes may be connected to form a coil, and the furnace may comprise more than one coil assembly. The rapid cooling may be carried out in the apparatus of Specification 1,165,908, comprising three concentric pipes which form a central chamber and two annular chambers. Cooling fluid, e.g. water, enters the top of the central chamber, which communicates at its bottom with the first annular chamber. The hot effluent passes through the second annular chamber, the inner wall of which forms a cooling surface. The outer wall of the second chamber may also be used as a cooling surface by welding cooling pipes to the exterior of the outermost concentric pipe. The cooler may operate in conjunction with a steam generator, and can be made self-regulating by a thermo-siphon effect. The hydrocarbon feed may range from ethane to crude oil, the examples using naphtha.

Abstract: 1,016,149. Brake slack adjusters. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Dec. 2, 1964 [Dec. 24, 1963], No. 50809/63. Addition to 826,701. Headings F2E and F2F. In an improvement in or modification of the automatic slack adjusting mechanism described and claimed in Specification 826,701, the second pawl engaging the ratchet portion 20 of the screw-threaded member 19 is eliminated and rotation of the screw-threaded member 19 in one direction is prevented by means of friction provided between a spring-loaded seat member 24 and the screw-threaded member 19 itself. In operation, when the nut member 19 and the piston rod 16 are moved outwardly in the course of a brake application stroke following the supply of compressed air to the brake cylinder, the driving pawl 25 rides up the ramp face of one of the helical ratchet teeth 20 out of engagement with the radial face of the preceding tooth towards a position in which the driving pawl engages the radial face of that one tooth, friction between the return spring-loaded seat member 24, forming part of the return spring assembly means, and the nut member 19 meanwhile preventing rotation of the nut member under the pressure exerted against the ramp face by the driving pawl 25. This friction permits rotation of the nut member in the reverse direction so that in the event of the driving pawl 25 having passed over the edge of a tooth in the ratchet portion 20 during the forward stroke, during the return movement in the course of the brake release stroke the nut member 19 is rotated in the direction to take up the slack. The invention may be applied to vacuumoperated brake actuating mechanisms.

Abstract: 1455856 Conveying sheet material W REIST 2 Nov 1973 [10 Nov 1972] 50959/73 Heading B8R [Also in Division F2] A clamp 7 for holding generally flat objects, e.g. newspapers, comprises jaws 1 and 2 pivoted by a pin 3 which are closeable by a scissor-like movement and enclose a gap 4 (Fig. 2) between the substantially flat jaws of the clamp which overlap when closed and preferably also enclose a passage 14 (Fig. 3), e.g. where the spine of the newspaper may be located. After receiving the newspaper (Fig. 1), the clamp and/or the newspaper may be rotated to the position of Fig. 2. The inclination of clamp 7 to the newspaper can be varied by altering the alignment of T-shaped holding portion 13 by a guide means. The clamp may be designed to have an adjustable clamp gap 4 (Fig. 4) by hingedly connecting the clamp jaws 22 with one another by a generally U- shaped resilient holding member 23 which functions in the manner of a hairpin spring. A multiplicity of the clamps may be incorporated in equipment or transport device which is suitable for handling and manipulating generally flat articles fed to the equipment in fish-scale fanned or overlapping formation. The transport device (Figs. 6 and 7) comprises a number of clamps 31 guided by travelling runners 32 in a U-shaped rail 33, the clamps being so mounted as to be capable of being rotationally or axially displaced, e.g. tilted, relative to runners 32. In Fig. 11, newspapers 57 are guided by transport belts 58 and 59 over an arched or domed region so that their leading edges 60 are prevented in fish-scale formation to the clamps 31. After seizing the newspapers, the clamp transport device can now leave the region of conveying band 59, and during this transport phase the clamps can be rotationally or axially displaced so that the newspapers hang vertically.
