Title: Rope-making machinery
IPC: D07B7/08
Filed: 1947-08-11
Abstract: 648,393. Rope-making machines. HALL'S BARTON ROPERY CO., Ltd., and HACKETT, J. A. Aug. 11, 1947, No. 22311. [Class 109] In a stop motion device for a rope-making machine, each strand 12, in the converging cone leading to the die passes over or through an individual guide 16 which rotates with the strand and is movable radially outward by centrifugal force, by spring action or by both, and such radial outward movement of the guide is arranged to actuate an electric device which stops the machine upon the breaking or releasing of a strand. The circuit containing the electric device preferably also includes a visual or audible signal to indicate the stoppage, as well as an electrically operated brake to bring the machine rapidly to rest. In the form shown, the guide 16 comprises a radial stem with an eye 15 and a contact element 18, which latter when the strand 12 is in normal tension is out of contact with a metallic ring 19, but contacts therewith on breakage or slackening of the strand. The stems 16 and metallic rings 19 form part of electric circuits each of which controls a circuit breaker 21, Fig. 1, capable of stopping the machine. The circuit breaker 21 is also in the main motor circuit including the main motor 23 for rotating the machine and a reversible controller 24 providing various speeds. The circuits of which the stems 16 and metallic rings 19 form part comprises a low-voltage circuit 25 led from the supply mains or transformer 26 to a brush contacting with a slip ring 28 on the cage 29 of the machine, an insulated wire carrying the current to the metallic rings 19. The stems 16 lead to a switch 30 directly controlling the circuit breaker 21 in the circuit of the main motor 23, so that when any one of the stems 16 closes the low-voltage circuit, the circuitbreaker 21 is operated and the machine stops. An electrically operated brake 34 and a signal 36 may also be disposed in the low-voltage circuit 25. The brake and lamp remain in operation after the circuit breaker 21 is broken, until a switch 41 is opened. Specifications 11042/84, 21101/10, 296,941, 303,851, [all in Class 109], and U.S.A. Specification 627,258 are referred to.

Filed: 1947-08-14
Abstract: 647,960. Inductances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 14, 1947, No. 22574. Convention date, Aug. 14, 1946. [Class 38 (ii)] A permeability tuning arrangement comprises a pair of coils connected in either series or parallel aiding relation, each coil being provided with a ferromagnetic core whereby the self and mutual inductance may be varied by relative axial movement of the cores and coils in unison, wherein each coil has a part of its surface flatter than another part thereof, the coils being disposed with the flatter parts of their surfaces facing one another, thereby improving the tuning range over that available in an arrangement employing coils of circular cross-section. A tuning device comprises two coils 20, 21 and a movable core, preferably of the powdered iron type, having four members 24-27 which may or may not be joined by a common yoke 28 but which are always arranged to move in unison. The effect of the external members 26, 27 is to provide, for a given core movement, greater changes in the self and mutual inductances of the coils and in the self capacitance of the assembly than would be obtained if the arrangement 'comprised a single coil and core, the changes being greater, but in a less and less proportion as the number of coil and core groups is increased above two to increase the tuning range. The coils may be formed to any shape (e.g. square, circular, rectangular, triangular) the tuning range increasing as the proportion of the coil peripheries in intimate contact with each other increases. The electrical connections between the coils may be series or parallel, aiding or opposing, the greatest tuning range being obtained with the parallel aiding connection. Yet further increases in the tuning range may be obtained by (i) increasing the ratio of length to diameter of the coils ; (ii) making the cores longer than the coils ; (iii) earthing the cores to increase the change in self capacitance ; (iv) using core materials of higher permeability ; (v) moulding the coils into a former of low-loss, high-dielectric-constant material ; (vi) the provision of additional cores on each side of the coils.

Title: Improvements in or relating to fluid-pressure operated control mechanisms
Inventor: HOLLINGS JOHN SHAW
IPC: G05D7/01
Filed: 1952-09-09
Abstract: 736,514. Fluid-pressure servomotor-control systems; valves. ROLLS-ROYCE, Ltd. Dec. 7, 1953 [Sept. 9, 1952], No. 22658/52. Class 135. [Also in Group XXXV] In a fluid-pressure operated control mechanism, an angular motion of a controller element which adjusts a fluid flow control device is produced by a displaceable sac 27 of rubber or like material subjected internally to a controlled or servo pressure and engaged externally on opposite sides by abutment means resiliently loaded so as to indent the wall of the sac to a variable extent dependent on the servo pressure, the controlled member being adjusted in accordance with the extent of such indentation. The sac may form part of a control unit such as is described in Specifications 716,254 and 716,255 in which the flow from a nozzle to a receiving chamber is varied in accordance with a variable condition by an obturator between them. Fig. 2 shows a unit 17 mounted on a hollow spindle 18 and having a pipe connection 28 on which the sac is mounted. The sac is compressed between a roller 31 supported within a chamber 15 and a hump 30 formed on the unit 17 partly by a resilient load applied to the unit 17 by a spiral spring 32, Fig. 3, and partly by a further resilient load applied by a resilient throttle tube 13 through a roller 16 on the unit 17. The servo pressure is applied to the sac 27 through a divergent inlet 26 and a duct 25 from a nozzle 24 supplied from the hollow spindle 18 and is controlled by an obturator 35 movable in a recess 29 about the same axis as the spindle 18. Fig. 3 shows the invention applied to the speed control of a gas turbine engine, the supply of fuel from an engine-driven centrifugal pump 10 being controlled by the action of the roller 16 on the throttle tube 13. Fuel from the pump enters the tube 13 by a passage 12a and passes to the fuel burners by a passage 12b. Fuel to provide the servo pressure is passed through a duct 20 and nozzle 23 to the hollow spindle 18. The obturator 35 is positioned in accordance with the engine speed by a shaft 41 supporting a metal skirt 39 concentric with a permanent magnet rotor 37 on the pump shaft 9. The magnet 37 is enclosed by a non-ferromagnetic cover 38. The drag on the skirt 39 is resisted by a spiral spring 42. The outer end of the spring 32 is fixed to a post 34 rigid with the skirt 39 and the shaft 41 so that movements of the unit 17 tend through the spring 32 to change the load on the obturator and the skirt 39. The reinforced rubber throttle tube 13 may have an insert 21, Fig. 4, of dumb-bell section or may have a pair of parallel spaced rods inserted in it to ensure complete closure between the convex surfaces of the roller 16 and a humped element 14.

Abstract: 305,108. Arnold, C., (Imperial Oil, Ltd.). Aug. 30, 1927. Mineral and tar oils, purifying.- Hydrocarbon oils, especially cracked naphtha or gasoline, are purified by passing the vapour in countercurrent to a stream of liquid carrying a finely divided solid adsorbent or absorbent. As shown, vapours from a still 1 pass through a fractionating column 6 with a cooling coil 8 into a treating column 10 with perforated plates 13 and an upper cooling coil 8<a>. Attapulgus clay or Fullers' earth preferably moistened with the liquid under treatment is discharged by a pipe 14 from a box 15 down the tower, and the purified vapours rise past the cooling coil 8<a> to a condenser 21. The vapours are condensed momentarily on the falling clay, which may contain a substance such as a metal oxide or sulphide to reduce the sulphur content of the oil. The liquid carried down with the clay is withdrawn from a tank 16 and returned to the still or to the fractionating column at points 18. In a modification granular clay is added dry, and the condensate forms the liquid washing it down the tower. Metal oxides or sulphides such as those of copper, lead or iron may be supplied with the clay or separately.
