Title: Improvements in or relating to means for applying brakes on trailer vehicles
IPC: B60T13/50
Filed: 1936-05-14
Abstract: 476,740. Fluid - pressure brakes. CLAYTON DEWANDRE CO., Ltd., WILLETT, S. E., and EDGE, S. H. May 14, 1936, No. 13706. [Class 103 (i)] [Also in Group XXVIII] The brake cylinder 21 of a trailer is controlled by a valve 18, operated by a servo-motor 12 controlled through a pipe 5, by a driver's valve 4 on the tractor. When the valve 4 is operated to disconnect the pipe 5 from the main reservoir pipe 1 and connect it to the atmosphere, air is admitted to the servo-motor 12, vacuum therein is destroyed and allows a spring to operate the valve 18 by rods 13, 17 and a lever 14 by which the valve may also be manually operated. The valve 18 connects the brake cylinder 21 to a vacuum reservoir 10. The valve 18 comprises a plate seated on a seating at the end of the pipe 19 by a spring and adapted to be unseated by a seating in the head of a piston operated by the rod 17. The pipe 20 is normally connected to atmospheric inlet 45 through this seating in the piston. The valve 4 comprises a piston operated by the brake pedal and adapted to seat on a valve controlling the connection 3 from the reservoir 1 and to open an atmospheric valve. The valves are formed in one piece. A coupling 26 in the pipe 5 between the tractor and the trailer comprises a valve 54, Fig. 4, in one part held away from its seat by an extension 53 of the other part 6. If the trailer breaks away a flange on the sleeve 6 presses on the links 56 which ride over spring pins 57 on a locking handle 58, releasing the sleeve 6 and allowing the.valve 54 to close.

Title: Improvements in take-up mechanism for knitting machines
IPC: D04B15/88
Filed: 1922-05-16
Abstract: 180,321. Wildman Manufacturing Co., (Assignees of Howie, K.). May 20, 1921, [Convention date]. Fabric take-up. - Take. up mechanism for knitting- machines is provided with a positive clutch having metal - to - metal toothed members which are so arranged as to be either all the way in engagement with each other or all the way out of engagement. The rolls 3 are journaled in a frame 2 mounted on a shaft 19 bearing in the main frame 1. One roll carries a worm-wheel 5 meshing with a worm 4<1> attached to which is a clutch 4 having a tooth or teeth on its upper face for engagement with the tooth 6x of a clutch 6 splined on a vertical shaft 18. The shaft 18 is driven by a gear on the lower end and the drive is transmitted, when the parts 4, 6 are in engagement, to the worm 4<1> which is loose on the shaft. The upper end of the sleeve 6 carries two flanges 6<a>, 6<b> in the annular groove between which a spring pin or plunger 10 carried by a box 2<1> on the frame 2 is received when the clutch is out of action. Another spring pin 11 co-operates with a cut-away part and a cam incline 6" on the lower flange 6" in releasing the clutch. As the fabric is knit off, the frame 2 gradually tilts into the position shown in Fig. 2, thereby allowing the clutch part 6 to drop into engagement with the part 4. If now the take-up rolls climb on the fabric, the frame 2 is tipped into the position shown in Fig. 3 and when the cut-away part at the under side of the flange 6<a> registers with the pin 11, the incline 6<11> rides up on the pin 11, the flange, 6<b> is lifted above the pin 10, and the parts are restored to the position shown in Fig. 1.

Title: Improvements in or relating to machines adapted for forming and inserting staples
IPC: A43D69/04
Filed: 1953-05-16
Abstract: 755,509. Continuous wire stapling machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BAGSHAW, C. M. May 17, 1954 [May 16, 1953], No. 13762/53. Class 89 (3). A continuous wire stapling machine has means for feeding wire across a staple former during a part of the machine cycle and means actuatable by an operator for varying the action of the wire feeding means when it is desired to form a staple of a length differing from that last formed which is rendered inoperative during that portion of the machine cycle during which the wire is being fed. As shown, the staple-length controlling mechanism is actuated by means of a rod 4 pivoted at one end to one arm of a bell-crank lever 6 pivoted to the machine at 8. The other arm of the lever 6 is slidably mounted on a treadle rod 12 which is positioned by an operator. Movement of the lever 6 is effected by a compression spring 14 and collar 18 on the treadle rod 12 which in turn is urged upwardly by a compression spring 22 bearing on a nut 24 on the rod 12 and a fixed plate 20 of the machine. Also mounted on the lever 6 for movement therewith is a plate 26 having teeth therein which engage a pawl 32, pivoted at 34, and having an angular face 37 which is engaged by an angular face 38 on a block 40 attached to a lower portion of a lever 42 pivoted on a pin 44. Thus, when the lever 42 is rocked clockwise as viewed in Fig. 2, the pawl 32 is held in full engagement with the teeth 30 on the part 26 so that if the rod 12 is depressed on movement of the lever 6 and consequently the rod 4 takes place, the effect being to load the spring 14 so that when the pawl 32 is released, after the wire feeding operation, the spring 14 rotates the lever 6 and adjusts the length of staple. The lever 42 is rotated to control the pawl 32 during the wire feeding portion of the machine cycle by a cam 70 which engages at that time a roll 50 mounted on a carrier 48 attached to the lever 42; limited relative movement between the carrier 48 and lever 42 is provided by means of pivot 46 and spring 58 so that should the member 70 come into engagement with the roll 50 at the instant when it is passing the point of a tooth, the spring 58 yields, thus preventing damage. Specifications 17439/05, [Class 17] and 296,743, [Class 17 (ii)], are referred to.

Title: Signalling circuit arrangement comprising a hybrid coil
IPC: B60P1/26
Filed: 1929-05-03
Abstract: 333,180. Standard Telephones & Cables, Ltd., and Roseway, W. N. May 3, 1929. Two-way systems.-In a hybrid coil system for coupling a four-wire to a two-wire circuit additional inductances are placed in the line circuit to provide a rising frequency attenuation characteristic which prevents transient distortion in long distant circuits. These additional inductances resonate with the incidental capacities between the conductors of the line windings. In the known arrangement shown in Fig. 1 the twowire circuit E, balanced by network ZN is coupled by means of the hybrid coil L1 - - L8 to the fourwire circuit T and R. The lower cut off of the line is raised by means of the condensers C. With this arrangement the attenuation loss between E and ZT varies with frequency as shown in curve 1 (Fig. 6) if the coils L1, L2 are wound simply on a common core whilst curve 2 is obtained if the coils are wound as a twisted pair. By adding additional inductances L9, L10 in the line circuit (Fig. 2), curve 4 (Fig. 6) is obtained. L9 and L10 are equal in value, which value is determined by the capacity between the twisted pair L1 L2 and the rise in loss required. For the curve shown the resonant frequency between L9 and C is at about 7000 cycles per second. The coils L9, L10 may be divided as shown in Fig. 3, different values and losses between E and R being obtained if the coils of L10 are aiding or opposing. The four coils L9, L10 may be wound on the same toroidal coil.

Title: Improvements in Apparatus for Extracting Dust from Gases and Vapours, applicable also for Collecting Particles of Flour, Cement and other Substances.
Inventor: GALLOT GEORGES ANATOLE
IPC: B03C3/60
Filed: 1916-09-28
Abstract: 110,774. Gallot, G. A., and Poussin, P. M. N. Sept. 28, 1916. Gases and vapours, electrically precipitating suspended particles from.- In apparatus for separating dust or liquid pacticles from gases and vapours, comprising a tubular perforated electrode and an inner electrode, the distribution of the electric field is improved and sparking at the ends of the electrodes is checked by placing insulating material between the electrodes at their ends, or by tapering or rounding off the ends of the inner electrode when this is cylindrical. Efficiency is thus increased, and the use of longer electrodes and higher electric pressures facilitated. The inner electrode may be a wire g, surrounded near the ends of the outer electrode d by insulators i, i<1> of glass, mica, ebonite, &c., which may be mounted on the wire or carried by bridges across the outer electrode. The outer electrode may be cylindrical throughout or flared at its ends. In the multiple arrangement shown, the gas traverses the outer electrodes from a common settling chamber a and pipe b. Dust &c. passes through the perforations in the outer electrodes into spaces f. The wire electrodes are supported by two rods k. k<1>. In another arrangement, the inner electrode is a tubular body with hemispherical ends. An electrode of similar outline may be constructed of metal strips projecting radially from a cylindrical body which has circumferential ribs to check the flow of gas between the strips. At their ends, the strips are bent to meet at two points in line with the axis of the cylindrical body. A number of wires mav be connected at two end points and spread by transverse disks to form a cylindrical cage with conical ends. A wire-gauze cylindrical electrode is mentioned. The electrodes may be vibrated to keep them clean. They may be charged by electrostatic machines, induction coils with rotary commutators and valves of the disk- and-point or rarefied-gas type, or static transformers with synchronous commutators or incandescent-cathode rectifiers. Condensers are placed in parallel with the separator. The apparatus may be used for removing smoke, poisonous dust, lead oxide, zinc powder, cement, plaster, flour, or kaolin from air, or carbon from gases in porcelain furnaces. Reference has been directed by the Comptroller to Specifications 109,227 and 120,573.

Abstract: 1,267,862. Earth leakage protective arrangements. L. WAJL, and S. C. JOHANANOFF. 19 March, 1969 [26 March, 1968; 7 June, 1968; 29 Jan., 1969], No. 14440/69. Heading H2K. An earth lea kage protective arrangement comprises a circuit-breaker 5, 11 and a capacitor 22 and the coil of a relay 19-connected across the supply, contacts 19/3 of the relay being connected in the circuit breaker actuating circuit and contacts 19/1 being connected in series with a silicon controlled rectifier 25 having its gate 27 connected to the metallic casing of an appliance. When a potential of sufficient magnitude appears at the gate 27, the rectifier 25 conducts to energize a relay 26 which opens its contacts to interrupt the supply to the coil 11 of the circuitbreaker. The capacitor 22 is discharged causing the relay 19 to release so that the arrangement is reset, the rectifier 25 ceasing to conduct, the relay 26 reclosing its contacts and the relay 19 being re-energized when the capacitor has recharged, providing the supply voltage is adequate. Initially a push-button switch 14 is operated to cause the energization of the coil 11  to close the circuit-breaker, the circuit of the coil thereafter being maintained over the contacts of the relay 26 until this relay is energized on earth leakage. Should the supply voltage fail or suddenly change, a transformer 15 and a circuit including a capacitor 38 and bridge rectifier 30 apply a triggering potential to the gate of the rectifier 25 causing it to conduct and effect opening of the circuit-breaker. Also, transformers 47, 48 and a diode 49 may apply a triggering potential to the rectifier 25 should the currents in the supply conductors differ. A test switch 32-and fuses 4, 4a, 4b and 12 are provided. When the arrangement is used to protect a three-phase installation, the test switch is connected across one of three resistors star-connected to the phase conductors, Fig. 2 (not shown).
