Title: Improvements in and relating to high tension electric circuit interrupters
IPC: G04B47/02
Filed: 1932-05-19
Abstract: 388,613. Oil-break switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Prince, D. C. ; 1424, Wendell Avenue, Schenectady, and Turnpenny, W.; 12c, Wilkins Avenue, Albany, both in New York, U.S.A.) May 19, 1932, No. 14293. Convention date, May 19, 1931. [Class 38 (v).] A multiple-break high-tension circuit-breaker of the self-generated oil-blast type has an oilfilled housing comprised of two identical insulating tubes 1, 2 connected to a flanged coupling member 3, supported on an insulator 4. An insulating partition 40 divides the housing into two compartments in the lower of which are situated a set of contacts connected in series by flexible conductors between line terminals 5, 6. Pairs of main contacts such as 13, 14 are mounted in insulating tubes 47 connected to relief openings in the partition 40 while other pairs of contacts such as 9, 10 are situated between the main pairs and remote from the relief openings. All the movable contacts such as 10, 14 are mounted on insulating cross bars 37 slidable on a pair of operating rods 35 which extend along the sides 'of both tubes 1, 2. Springs are threaded on the rods 35 so as to bias the contacts to the closed position and sleeves on the rods engage the cross bars, when the rods are moved to the right, to separate the contacts. The actuating mechanism comprises an insulating rod 22 .which passes up the insulator 4 and is connected to a rod 25 having a collar 27 and compression spring 29 at its upper end. A crank 30 pivoted at 31 to the casing, is pivoted at 32 to the actuating-rod 22 and is connected at 34 to the operating rods 35. In the position shown the circuit is closed. On release of the rod 22 it moves upwards under the action of spring 29 thus turning the crank 30 anticlockwise and moving the operating rods 35 to the -right to open the circuit. The arcs formed at pairs of contacts such as 9, 10 generate pressure causing oil to be forced up through the relief openings past contacts such as 13, 14 and thus extinguish the arc. This happens simultaneously at all pairs of contacts. A chamber 56, filled with pebbles and provided with a perforated lid, allows gas to escape and minimizes oil throw. Specification 193,136, [Class 38 (v), Electric switches &c.], is referred to.

[Class 135] A steam-regulator or like valve as claimed in Specification 285,589, [Class 135], comprising a number of concentric valves contained in the body or cathead one or more valves or portions thereof acting piston-wise in a balancing chamber formed in another valve, has one of the component valves ported so as to enable steam to be passed in small amounts for purposes other than main supply and under control of the innermost valve, in advance of or during operation of the composite valve in full capacity. The small steam supply may pass to the main pipe of a locomotive for " drifting," or through an auxiliary pipe to close poppet valves in a cylinder steamchest or to prevent overheating of superheater elements or to operate other valves and fittings. In Fig. 3 the outermost valve B of the concentric valves B, C, D is ported at b2 leading a small amount of steam, on lifting of the valve D, from the balancing chamber y to an external port p. Or the port p may be closed and the small supply led to the main pipe at S through. a port in the web b<5>, Fig. 5 (not shown). In Fig. 6, on first opening the innermost valve D, steam available for drifting passes through ports c<1>, bl in the valves C, B, to the main pipe ; being subsequently cut off by the lifting of an annular valve D<1>, between which valve and the valve D steam reaches the balancing chamber y. In Fig. 7 (not shown), the distance piece F is modified to fulfil the function of the valve D<1>, Fig. 6. In Fig. 8 (not shown) a fourth valve is arranged between the valves D, C, operation first opening valve D and admitting steam to the balancing chamber, and subsequently lifting the fourth valve (drifting position) to pass a small supply through ports in the valves C, B. A second small supply may be obtained in this construction by providing additional ports similar to the ports b<2>, p, Fig. 3. Both the valve D and the fourth valve of Fig. 8 may admit steam to the balancing chamber, in which case the valve C need not be ported, Fig. 9 (not shown). In Figs. 10, 11 (not shown), the small supply passes to a chamber at the bottom of the cathead, communicating either with the main or an external pipe.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T8/18
Filed: 1932-05-23
Abstract: 401,753. Fluid-pressure brakes. BROWN, D. F. and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. May 23, 1932, No. 14607. [Class 103 (i).] In fluid-pressure brakes comprising light and load brake cylinders, a control valve 4 first admits fluid rapidly to the light cylinder 2 only, then rapidly to the load cylinder 3 only, then slowly to both cylinders. The load cylinder is released rapidly prior to the release of the light cylinder. In the vacuum brake shown the valve 4 is controlled by a diaphragm 15 subject to the vacuum in the upper and lower chambers of the cylinder 2. When air is admitted to the train pipe 1 on brake application, it passes by passage 20 past valve 4 to the lower chamber 7 of the cylinder 2 until the increased pressure on the right of the diaphragm moves valve 4 on to its other seat closing the train pipe from cylinder 2 and opening it to the lower chamber 10 of the cylinder 3 through part 1a. When the pressure in this cylinder has risen above that in the cylinder 2, a non-return valve 26, in passages connecting the two cylinders is lifted, so that both cylinders are supplied through the part 19. In release the stem of the valve 4 displaces a ball valve 31 to connect the upper and lower chambers of the cylinder 3 so that it is rapidly released. The load brake cylinder 3 may be cut out by means of a cock 35 in the passages 21, 30 and connected to atmosphere.

Abstract: 955,181. Starting prime movers. C. A. V. Ltd. April 6, 1962 [April 24, 1961], No. 14683/61. Heading H2H. [Also in Division F1] The invention relates to electric starting mechanism for internal-combustion engines of the kind comprising in combination an electric motor, an axially movable sleeve on which is formed or secured a pinion 4 adapted for engagement with a toothed wheel 5 on the engine, the sleeve being mounted on and having quick-pitch screw-thread connection with the motor armature shaft 2 or a shaft connected thereto, a solenoid core 9 mounted on the sleeve, the core and sleeve having interacting parts whereby axial movement of the core in one direction will impart a corresponding initial axial movement to the sleeve, to effect initial engagement of the pinion with the engine wheel, a solenoid winding 10 surrounding one end of the core a resiliently supported member carrying contacts of a pair of switches 17, 19, 18, 20 respectively and a catch 26 co-operating with the member the arrangement being such that in use when the initial movement has been imparted to the sleeve by energization of the solenoid the first switch is closed by tilting the member to cause rotation of the motor at relatively slow speed and thereby cause the screw thread connection to cause the sleeve to partake of further axial movement to engage the pinion fully with the toothed wheel of the engine this further movement of the sleeve causing the latter to release the catch and allow the second switch to close thereby applying full power to the motor. According to the invention the catch is loaded in a direction to engage the member by means of a spring 29 one end of which acts upon the catch whilst the other end acts upon the core 9 so that when the initial movement has been imparted to the core the force of the spring acting to hold the catch in engagement with the member is reduced. The sleeve 3 may be non-magnetic. Specification 742,024 is referred to in the Provisional Specification.

Abstract: 628,907. Agricultural implements. FERGUSON, Inc., H. June 5, 1947, No. 14843. Convention date, June 5, 1946. '[Class 6(i)] [Also in Group XXXII] In a coupling between a tractor, of the class described in Specifications 470,069 and 470,087, and an agricultural implement, the operational characteristics are similar to those described in Specification 602,291 but the mechanism is wholly mechanical itself and adapted for use only with a tractor having an automatic control of the power lift. The mechanism is characterized in that the lower draft link is formed in two parts, 32 and 34 both pivotally connected to plates 33 on each side, so that they may be displaced out of alignment at an angle limited by the engagement of the part 34 with the bolt 41. This arrangement provides a fore and aft rocking of the implement, when the draft link is raised or lowered, thereby altering the angle of penetration of the nose-part, resulting in an optimum manner of application of the load to the tractor wheels, effective depth control and a quick run in and run out of the implement. In a modification the coupling is shown adapted for fitting to the draft links of a standard " Ford " tractor.
