Abstract: 538,923. Valves. JOHNSTON, N. F. March 29, 1940, Nos. 5724, 8378 and 14915. [Class 135] A remote control apparatus for a loaded valve comprises a hand lever carrying a pawl adapted to co-operate with the teeth on a pulley coupled by a flexible connection with the valve member and arranged so that movement of the lever beyond the full open position causes the valve to close. In the form shown in Fig. 1, a grooved pulley 3 loose on a shaft 4 is connected by a cable 12 passing over a guide pulley 13 and chain 14 passing over a sprocket 15 to the spindle 17 of a sluice valve 18 loaded by a spring 2. The pulley 3 is rotated to open the valve by a hand lever 5 loosely mounted on the shaft 4 and carrying a pawl 6 adapted to cooperate with teeth 7 on the side of the pulley. The pulley is held in its new position by a pawl 10, and the valve is held in its open position by a pair of pawls 20 held in their operative or inoperative positions by blade springs 23 engaging flats 21, 22 on the pawl bosses and co-operating with a notched plate 16 secured to the valve spindle. To close the valve the lever 5 is moved beyond its fully open position to cause a bail 8 on the pawl 6 to engage a fixed stop and so release pawls 6 and 10. At the same time cam surfaces on the plate 16 move the pawls 20 to their inoperative positions. As the valve approaches its closed position the underside of the plate 16 engages pin 24 to return the pawls 20 to their operative positions. In the form shown in Fig. 4 a similar local actuating device is fitted to the sprocket 15, the local retaining pawl being connected by a cable with the remotely controlled actuating cable. To provide a slow-closing action the lift valve member has a tubular extension slidably mounted over a packed projection 31 on the valve cover, said extension having a restricted vent passage 35.

Abstract: 747,727. Magnetic couplings; magnetic structures. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 3, 1953 [March 6, 1952], No. 5871/53. Classes 35 and 38 (2). A magnetic device for converting rotary motion in one direction into reciprocating motion, or vice versa, comprises two members each having a magnetic system comprising permanent magnetic poles, which, along a line connecting each such pole with the adjacent pole, are of alternate polarity, the conversion of motion being due to the interaction of the fields of the two said members. Fig. 1 shows a sectional view of such a device having a rotary member 1 comprising a disc-shaped element 3 of permanent magnetic material axially polarized and a second member 2 having a disc 4 similar to disc 3. The member 2 is constrained from following the rotating force of the member 1 by two springs 6, 6<SP>1</SP> which permit the member 1 to reciprocate as the member 1 rotates. The springs 6, 61 may be replaced by a diaphragm forming part of a diaphragm pump or a siren. In a modification, the element of the reciprocating member 2 is arranged between two elements of the rotary members 1 as in Fig. 3 (not shown). Fig. 4 shows a rotary member 1 carrying two cylindrical permanent magnets 12, 13 while the reciprocating member 2 has an external permanent magnet 14 which is so carried by a diaphragm 7 that it can reciprocate axially along the outer peripheral surfaces of the magnets 12, 13 as the latter rotate. Besides the diaphragm 7 there may also be a stationary braking permanent magnet 15 surrounding the reciprocating magnet 14. In a further modification shown in Fig. 5, the member 1 is stationary and it has a core 20 with an A.C. fed coil 19 on its central limb and two permanent magnets 12, 13 located as shown, while the member 2 is arranged to reciprocate and rotate under the action of the electromagnet and permanent magnets. Also, instead of having rectangularly shaped poles for the permanent magnets, there may be zig-zag poles having the appropriate N and S polarity and neutral zones. The permanent magnetic material of the magnetic circuits has a retentivity B which, measured in Gauss, is smaller than four times the coercive field strength  B H C  measured in Oersted. Specifications 708,127, 745,911 and 747,724 are referred to.
