IPC: F16K17/08
Filed: 1966-08-15
Abstract: 1,157,495. Valves. SWINNEY BROS. Ltd. 16 Aug., 1967 [15 Aug., 1966], No. 36377/66. Heading F2V. In a pressure relief valve, the closure member C is attached to an end plate A of a bellows B and is biased on to its seat by compressed air supplied at a predetermined pressure to the bellows. Depending downwardly from the plate A is a piston-rod D which carries at its free end a piston E, the piston having therein a plurality of passages J and being movable relative to the rod between a shoulder H formed on, and a nut F secured to, the rod there being a small radial clearance between the piston and its housing G. Upon the valve opening, air within the lower part of housing G forces the piston against the shoulder H so uncovering passages J and so permitting the air to pass to the upper part of the housing. Return movement of the closure member is damped and retarded by virtue of the fact that the air in the upper portion of housing G forces the piston E on to nut F, so closing passages J, and can then only return to the housing lower part via the small radial clearance, the arrangement thereby serving to prevent water hammer.

Abstract: 793,127. Magnetic amplifiers. COLLINS RADIO CO. Dec. 23, 1955 [May 16, 1955], No. 36913/55. Class 40 (4). In a resetting type magnetic amplifier comprising a pair of cores 7, 8 having a rectangular hysteresis loop, output circuits feeding a common load 13 include windings on each core, and the output from the winding on core 8 is controlled conjointly by a reset generator 10 and the output signal through the windings on core 7. The amplifier input which is applied across a resistor 20 combines with the output of reset generator 9 to regulate the output from A.C. source 4 through the winding 7. The output is a function of the firing angle. A portion of the output which is diverted through a diode 16 develops a current through a resistor 6 which aids the reset current applied to core 8 by a generator 10 during the firing half-cycle of the circuit including core 7. The reset of core 7 is regulated by the potential developed across a resistor 19 when the circuit including windings on core 8 is firing. Potentials shown are those occurring during this period. Modified circuits which include resistors for improving the time response are described with reference to Figs. 2 and 3 (not shown) and in the former embodiment the control circuit on core 8 comprises a tapped portion of the output winding.

Abstract: 779,074. Magnetic recording and reproduction. PROTONA PRODUKTIONGES. FUER ELEKTRO-AKUSTISCHE GERAETE GES. Dec. 28, 1954 [Dec. 28, 1953], No. 37456/54. Class 40 (2). [Also in Group XXXIX] In a circuit using a single recording/reproducing head SK, a single transducer MT for sound reception and emission, and the same amplifier V for recording or reproducing, the change-over is effected by means of switches S1, S2, whose centre pole is connected to the chassis. Thus with S1 and S2 in the full line positions the output from the transducer MT feeds the input transformer of the amplifier V and the input to the reproducing head S is obtained from the amplifier output transformer, whilst with S1 and S2 in the dotted line position connections are made in the opposite manner. The presence of an earthed spring between the contact springs leading to the two circuits helps to decouple these two circuits so preventing mutual interference. The switch S3 energizes an obliterating head LK and a magnetic bias winding VM in the recording position. In the play-back condition an adjustable potentiometer S4 regulates the output volume of the transducer. A pick-up coil J for recording telephone conversations is also provided. In a modification, Fig. 3 (not shown), a separate microphone and loud-speaker are provided and switched-in as required. The invention is more particularly applied to a pocket-sized recorder.
