IPC: H04R11/00
Filed: 1922-12-14
Abstract: 212,648. British Thomson-Houston Co., Ltd., Butcher, J. H., and Young, A. P. Dec. 14, 1922. Magnetic instruments.-In sound transmitters or emitters, such as telephone receivers, the magnetic circuit and coil are arranged within a closed hollow casing 15 which functions as the diaphragm of the instrument, the moving element being connected to opposite sides of the casing. The casing 15 is preferably of boxwood, the magnets 17 being secured to the ends 14, which may be of aluminium. These ends 14 are carried on brackets 12 on a frame 11. The magnetic circuit may comprise two structures of soft iron laminations, each in the form of a rectangular C, with operating coils 18 mounted thereon. A permanently magnetized reed 22 is arranged in the air gaps and supported by rods 23 connecting it to the casing. The ends of the rods are screwthreaded and co-operate with nuts 25 for the purpose of adjustment. The reed may be pivoted at its centre. A longitudinal window of mica may be provided in the casing. The coils are wound so as to produce similar poles on the same side of the reed. The pole-pieces of the C-shaped magnets may themselves be permanent magnets of cobalt steel, or the main core may be a permanent magnet; in either case the actuating coils are disposed round the reed, which may be polarized or unpolarized. In another magnetic circuit, Fig. 3, the ends of permanent magnets 32 are connected by yokes 33 to pole-pieces 34, and a reed 22 is mounted between the pole-pieces in brackets 35 of non-magnetic material. Operating coils 18 are mounted around the reed so as to produce a consequent pole between the polepieces. In a further modification, in which the magnetic circuit and coils are associated with a closed hollow casing, the magnetic circuit, Fig. 4, comprises a number of curved magnets 36 arranged in the form of a circle, or a number of straight magnets in the form of a polygon. On one side of each magnet are fixed pole-pieces 37 to carry the actuating coils. A co-operating magnetic disc carried by the casing 15 is provided adjacent the faces of the pole-pieces. A similar structure may be used co-operating with a magnetic disc carried upon the other side of the casing 15. According to the first Provisional Specification, the reed which co-operates with two C-shaped magnet structures may be pivoted at its centre and connected at one end to a diaphragm or at both ends may be connected to diaphragms. With the arrangement shown in Fig. 3, the middle of the reed may be connected to a single diaphragm. According to the second Provisional Specification, a single bar-magnet, with L-shaped pole-pieces at each end on which are the actuating coils, may co-operate with a diaphragm clamped round its edge in brackets, and a number of curved or straight magnets in the form of a broken circle or polygon with polepieces adjacent their ends may co-operate with a diaphragm.

Abstract: 619,025. Control of D.C. motors. WADSWORTH & SONS, Ltd., W., and KERSE, W. H. Nov. 20, 1946, No. 34434. [Class 38 (iii)] A direct-current lift-motor is supplied through a grid-controlled mercury-arc rectifier, the output voltage of which is controlled by a phase-shifting regulator, preferably of the rotary type, and means are provided for automatically adjusting the regulator respectively in opposite directions so as to accelerate and decelerate the lift. A motor-driven shaft a is geared to the rotor of a phase-shift regulator i<1>, through means comprising a clutch d which is operable by means of a solenoid e,. in such manner that, when the clutch is made, the regulator is turned towards the full-speed position upon rotation of the shaft a in either direction. The shaft a is also geared to the regulator, through clutches m and n operable by a solenoid o which is energized when the solenoid e is de-energized, so that the regulator may be moved to the low-speed position upon rotation of the shaft a. The regulator driving arrangements comprise pulleys h and q which are provided with counterweights tending to turn them to a neutral position, the pulley q being returnable to such positiori when the clutch r is freed, so that the deceleration drive can be made operable without reference to the position of the regulator as determined by the accelerator drive. Means are provided to limit the movement of the regulator shaft in either direction. The operator is provided with a switch, in one position of which the solenoid e is maintained energized, and in another position, the said solenoid is controlled by floor switches so that it is de-energized, and the solenoid o is energized, to decelerate the car as it approaches a floor in either direction. The period of deceleration of the car may be altered by adjustment of the drive between the shaft a and a shaft i. In a modification (Figs. 4-6, not shown), a shaft is driven from the lift-motor by a chain and free-wheel sprocket so as to rotate in one direction only irrespective of the direction of travel of the cage, and clutches are provided for coupling said shaft to gearing for rotating the regulator respectively in opposite directions..

Abstract: 429,817. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Craig, J. F. ; 49, Beverly Road, Upper Monclair, New Jersey, U.S.A.) Nov. 30, 1934, No. 34456. Convention date, Dec. 1, 1933. [Class 103 (i)] A valve device for fluid-pressure brake apparatus comprises two abutments controlling respectively the supply to and release from a brake cylinder of fluid under pressure, each abutment being subject to the opposing actions of the brake cylinder pressure and the pressure of fluid supplied from the drivers brake valve or its equivalent. A pair of independent pistons 19, 20 are slidable in a cylindrical bushing 13. The chamber 25 between the pistons is connected to the drivers valve by passage 26 and the chambers 21, 27 are connected by radial ports 22, 28 to a chamber 17 surrounding the bushing and thence to the brake cylinder by passage 18. The piston 20 carries a supply valve 33 in a chamber 31 connected by passage 32 to the reservoir. Normally, the chamber 25 is connected to atmosphere through the drivers valve, and the pistons are in the position shown with the piston 19 abutting on an extension 37 of the piston 20 so that the chamber 21 and thus the brake cylinder is connected to atmosphere through passage 24. When pressure fluid is admitted to the chamber 25 the piston 19 moves to left to seat a ridge 23 thereon against the casing to close the release passage 24 and the piston 20 unseats the valve 33 and when the pressure in the chamber 27 and brake cylinder is substantially equal to that in the chamber 25 the piston 20 returns to seat the valve. A graduated release of the cylinder pressure may be similarly obtained by partially releasing the pressure in the chamber 25 through the drivers valve, the piston 19 moving to unseat the ridge 23 until the pressure in chamber 21 has fallen substantially to that in the chamber 25. The bushing 13 has an end plate 15 which is clamped between the casing 10 and a cover 11 and upon detaching this the bushing with the pistons may be removed without disturbing the casing and the pipe connections.
