Title: Improvements relating to fluid pressure braking systems for railway and like vehicles
IPC: B60T13/68
Filed: 1946-08-30
Abstract: 616,230. Fluid-pressure-operated brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Aug. 30, 1946, No. 26187. Convention date, Feb. 16, 1944. [Class 103 (i)] [Also in Group XXXVII] In automatic compressed air brake systems in which the return of the triple valves to the release position is expedited by energizing magnet valves to vent the auxiliary reservoirs until the pressure therein falls slightly below that in the brake pipe, energization of these valves is prevented if the brake pipe pressure has in the application of the brakes been reduced below a certain value, until the brake pipe has been recharged. Excessive loss of pressure in the reservoirs is thus avoided. As shown, a switch, Fig. 1, controlled by brake pipe pressure is arranged in the train wire of the release valves and comprises a flexible diaphragm 20 subject on its under face through port 4 to the brake pipe pressure opposed by a spring 27. Annular valve members 23, 23<SP>1</SP> are adapted to seat on passages 17, 30. The passage 17 is open to the chamber above the diaphragm, and thus to atmosphere at 32. The passage 30 with passage 29 connects the chambers below and above the diaphragm. The pressure of the spring 27 is adjustable by a nut 28. The diaphragm rod 12 carries a contact 11 adapted to bridge contacts 9, interposed in the train wire. With the brake pipe pressure at normal value the parts assume the position shown. If in an application of the brakes the pressure falls to a relatively low value, the diaphragm is deflected downwards by the spring 27 and by initially uncovering the passage 29 the fluid pressure on its two faces is equalized so that it moves rapidly to disconnect the contacts 9, 11 and to seat the valve member 23<SP>1</SP> and also a valve 25 at 19. Also the valve member 23 is unseated by engagement with a flange 23a thereon of the edge of a cup-shaped member 22, thus connecting the upper side of the diaphragm to atmosphere. When in the release operation the brake pipe pressure acting on the relatively smaller area of the valve 25 reaches the normal value, the spring 27 is overcome and the diaphragm is deflected upwards to re-close the contacts. During the latter part of this movement, the valve 23<SP>1</SP> is unseated by engagement with the flange thereon of the edge of the cup-shaped member 22<SP>1</SP>. In order that the switch may not be operated to close the contacts until the predetermined pressure has been attained throughout the brake pipe, the port 4 is connected to the throat of the venturi passage in the usual feed valve which is of the kind described in Specification 236,161, [Class 135]. In the Specification as open to inspection under Sect. 91, the triple valves may be such as described in Specification 616,145. This subjectmatter does not appear in the Specification as accepted.

Filed: 1935-09-24
Abstract: 466,411. Fluid-friction brakes. BARTRAM, R. Sept. 24, 1935, Nos. 26395 and 35819. [Class 103 (i)] A fluid-friction brake comprises vaned rotor b<1> rotating about a vertical axis in a casing having on its inner surface opposed to the periphery of the rotor, pockets so fashioned as to redirect streams of liquid back on to the rotor. The quantity of liquid acting on the rotor can be varied. To produce braking, liquid is directed on to the vanes b<1> by a pipe d into which liquid is forced by centrifugal force by means of the chamber c rotating with the shaft a. Liquid is supplied to this chamber when braking is required from a reservoir a2 by means of a three-way valve e. Liquid also collects in the braking chamber a<3> and retards the vanes. Liquid is returned to the reservoir a<2> from the chamber a<3> by the cock e. Curved pockets may be formed on the interior of the wall of the chamber a<3> to direct the liquid back on to the blades and produce further braking. In a modification, the braking chamber is formed under the base of the basket f, the motor vanes being secured to the basket. In a further modification, liquid is contained in a reservoir which may be raised so that liquid is forced up through a grid on to the rotor vanes. In a modification of this form the rotor and the base of the reservoir have vertical annular perforated ribs which interfit when the reservoir is raised. Specifications 4842 /93 and 9943 /02, [both in Class 80], are referred to.

Title: Improvements in or relating to a device for and methods of forging blanks consisting of several non-coaxial volumes
IPC: B21K1/08
Filed: 1968-06-06
Abstract: 1,207,236. Forging crankshafts. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (St. Chamond, Firminy, St. Etienne, Jacob-Holtzer). 6 June,- 1968 [21 June, 1967], No. 26967/68. Heading B3H. A crank-shaft is forged from a billet 1 by a pair of dies 4, 5 which are held in a movable die block 2 and a fixed crosshead 3 respectively and the die block is moved in a direction at an angle to the billet axis to upset the billet and form a crank-shaft web between the dies. The size of the web may be determined by the volume of the billet or by a retaining die ring 6 so that the dies 4, 5 and the ring form a closed die. The bearing faces of the dies 4, 5 may be initially non-parallel, Fig. 7 (not shown), so that the crank-pins formed are non-parallel when the dies are abutted. A double set of tie-rods or columns 9, 10 are provided to absorb the forging load and intersect at the centre of gravity of the formed web. The die block 2 is raised by piston-cylinder assembly 8 and slides on a slideway 12 of the press frame 11.  The apparatus can be modified for multi-throw crank-shaft forging, Fig. 10 (not shown). This apparatus comprises a pair of two-part dies (14), (15), mounted in a fixed crosshead (17) and a slide (16). The crosshead and slide each have apertures (18), (19) aligned with the die apertures to allow axial movement of the billet for the separate forging of each throw. The billet is rotated about its axis and/or a transverse axis after each forging to correctly position the crankpins. The billet may be forged hot or cold and heaters in the form of induction heaters or gas burners may be provided in the device.

Title: Improvements relating to the electrical driving of machines on the constant current series system
IPC: H02K7/102
Filed: 1921-10-12
Abstract: 191,795. Austin, G., Macfarlane, J. C., and Macfarlane, W. A. Oct. 12, 1921. Dynamos, regulating; motors, controlling. - A continuous-current motor for use in a constantcurrent series system which is controlled by shifting the brush axis relatively to the field magnet axis is provided with an overspeed braking device adapted to change the relative positions of the brush axis and field magnet axis so as to reduce the torque of the motor on the attainment of a predetermined speed. The brushes 5, Fig. 1, are connected to a gear-wheel 6 meshing through pinions 8, 9 with an internal gear-wheel 7 on a drum 11, so that by turning the handle 15 in either direction the brushes 5 are moved in the opposite direction. Should the speed of the armature exceed a predetermined maximum limit, weights 13 carried by a disc 12 on the armature shaft move outwards into engagement with the drum 11 and so move the brushes towards the neutral or no-torque position. Where it is desired to allow the motor to run up to speed in one direction only, and where the handle must be moved into the reversed position to allow for regenerative braking, a ratchet and pawl connection 18, 19, Fig. 3, is provided between the disc 12 and drum 11 by which the brushes are forced back to the neutral position should the motor start to rotate in the wrong direction. In a modification, the casing carrying the field magnets is mounted so that it can be rotated against springs which normally hold it in its neutral position. In this case the handle 15 is connected directly to brushes 5 and the casing is connected through toothed gearing to the drum 11. Where it is desirable to lower the speed limit as the brushes are moved towards the maximum torque position, the friction surfaces of the drum 11 and weighta 13 are formed as conical surfaces and the drum 11 is moved axially when the handle 15 is moved. This endwise movement is effected bv a pin 30, Fig. 7, fixed to the casing cover 16 and engaging in an inclined slot 31 in the hub of the frame member 11. In order to prevent power being returned to the prime movers driving the generators should one or more of the motors return power to the line, the generators may be provided with an overspeed braking device as described above. The drum member of this braking device may be fixed or it may be movable and connected to regulating gear. Alternatively, a polarized relay may be provided to control a brake or to operate regulating devices. The relay may be a differentially-compounded motor with the shunt field winding connected across the generator terminals, and with the armature and series field winding connected in series to carry the normal full current of the system. The invention is particularly applicable to motors for driving cranes, hoists, haulage and winding-gears, centrifugal drying-machines &c., and for driving auxiliary machines on board ships, such as capstans, winches, windlasses, steering-gears &c.
Patent GB-601137-A (GB)
Title: Improvements in or relating to automatic controls for gas turbines
IPC: H02P23/16
Filed: 1945-10-16
Abstract: 601,137. Automatic control systems for speed control of gas turbines. BRISTOL AEROPLANE CO., Ltd., and FORTESCUE, P. Oct. 16, 1945, No. 27044. [Class 38 (iv)] In an automatic control system for gas turbines, the change of a variable, e.g. speed, from a datum produces an outof-balance voltage in a bridge network which is detected by a sensitive relay which selectively energizes a control relay and increases the state of unbalance by applying the control relay current to the bridge network until the control relay is actuated, thus to regulate the automatic control and to restore the initial state of unbalance. In the embodiment alternator 5, driven by the turbine (not shown), energizes polarizing relay 6, the armature 9 of which vibrates between contacts 7 and 8. The network 11 is connected to battery 17 at points a, b and the condenser 10 is charged and discharged thereby as armature 9 moves from contact 8 to 9. For given values of condenser 10 and resistor 12, 13, 14, 15, 16, the network zero balance potential, measured between points c and d, occurs at one turbine speed, this datum speed being alterable by variation of the value of resistor 12. At turbine speeds other than the datum, the voltage developed between c and d energizes and operates the sensitive relay 18 of which the armature 19 moves either to contact 20 or 21 depending upon the sense of the network out-of-balance potential. If the circuit through contact 20 is made, current passes through coil 22 of control relay 23, to the junction of resistors 13 and 14, to amplify the existing balance. The resulting increase of pressure between armature 19 and contact 20 raises the current through coil 23 sufficiently to move contactors 24 and 39 simultaneously in a direction opposite to the arrow 25, against spring action. A circuit is then made through contactors 24 and 28 of control relays 23, 31 and the armature 17 of motor 27 with battery 17, the motor 27 thereupon rotates the valve 33 to control the flow of gas along pipe 35 to the turbine, the speed of which is restored to the datum. The contactor 39 when energized contacts coil 22 with the junction of resistors 15 and 16 and restores the initial state of unbalance of the bridge and consequently the sensitivity. If the change from the speed datum is such as to cause the armature 19 to move to contact 21, the control relay 31 operates to move the valve 33 in the reverse direction and to restore the sensitivity as before.
