Title: An improvement in or relating to pressure-relief valves
IPC: F16K17/16
Filed: 1947-12-16
Abstract: 632,480. Pressure-relieving devices for fluids. BLAKEBOROUGH & SONS, Ltd., J., KLOUMAN, F. A., and DUNKLEY, W. H. Dec. 16, 1947, No. 33206. [Class 135] In a pressure-relieving device, e.g. for a steam condenser, a thin metal diaphragm b, open to atmospheric pressure on its upper surface and to condenser pressure on its lower surface, is fixed at its centre beneath a transverse bar f on a bolt c slidable in a grid a<SP>3</SP>, the periphery of the diaphragm and the ends of the bar being held between a rubber ring e and a shoulder a<SP>4</SP> on the casing. The diaphragm normally rests on a grill d supported by the grid. When the condenser pressure exceeds atmospheric pressure, the diaphragm is raised to take up the movement of the bolt c, this movement causing the periphery of the diaphragm to be pulled from between the ring and the shoulder. The diaphragm then folds about the bar f to a shape b<SP>1</SP>. In a modification, the bolt c is fixed.

Title: Coder and decoder devices
IPC: G11B27/13
Filed: 1974-07-26
Abstract: 1523281 Remote control; telephone answering system ANSAFONE Ltd 28 July 1975 [26 July 1974] 33228/74 Heading G4H In a remote control system, a transmitter, Fig. 1, sends a coded "access" signal comprising at least two groups of different frequencies to a receiver, Fig. 2, associated with apparatus to be controlled, whereby to enable it to receive subsequently transmitted control signals without the need for further access signals. As described, the apparatus to be remotely controlled is a telephone answering machine. A telephone connection is first set up, and the access signal, comprising three groups of three frequencies fa, fb<SP>1</SP>, fc is then sent. An acknowledgement tone is returned, then a control signal (play, erase, record, &c.), comprising a group of three frequencies fa, fb, fc, is sent, and a second acknowledgement tone is returned. Transmitter (Fig. 1).-The access signal is generated by depressing switch A. This causes a delay D.C. to switch off a transistor TR1 (so that an oscillator Tx can generate frequencies fa, fb<SP>1</SP> and fc); switch off a transistor TR2 to enable a ring counter RC; and start a clock CPG. Outputs 3, 5, 7 of the eight outputs of RC are sequentially connected to a "plug" P1 wired to give the address of the desired receiver. Three of the eight outputs of P1 actuate a decimal/binary converter DB which produces three sequential outputs (abc), causing Tx to generate three sequential groups of three frequencies fa, fb<SP>1</SP>, fc. These frequencies are fed via filters F1, F2 to an acoustic transducer TD which is held close to the mouthpiece. A command is subsequently selected by means of a switch 1-7. A corresponding output (abc) causes Tx to generate a group of frequencies fa, fb, fc. Since TR1 is on now, fb rather than fb<SP>1</SP> is produced, thus enabling the receiver to discriminate between access and control signals. Receiver (Fig.2).-The incoming frequencies are received at RX whose 3-bit output is fed to a binary/decimal converter BD. When an access signal is received, a "plug" P2 (corresponding to P1 in the transmitter) produces outputs a, b, c (one for each group of frequencies) which are fed to gates G, latches L and monostables M so connected that if each group is received within a predetermined time after the preceding one, then a gate G10 is enabled. The output of this gate is fed to a transistor VT1 to turn it on so that fb rather than fb<SP>1</SP> will be recognized, and via an integrator C10, R34 to enable gates G1-G7 through one of which the control signal will eventually pass.

Abstract: 967,997. Photo-electric control of lamps. R. L. SEIDLER. Sept. 29, 1960, No. 33456/60. Heading G1A. [Also in Divisions G4, H2 and H3] In apparatus including at least one multivibrator for flashing a lamp according to a predetermined programme, the output of the multivibrator is gated by a photo-sensitive cell so that flashing takes place only when the photo-sensitive cell is unilluminated. The output of the photoresistance 12 is passed via a control circuit 13, (see Division H3), which acts as an amplifier and trigger, to gate the output of two synchronised free-running multivibrators 14A, 14B and a monostable multivibrator 14C so that when the level of illumination on the photo-resistance is below a predetermined level the lamp 11c flashes a repetitive signal in form of a morse "A". By using the multivibrators 14A; 14B; only, group flashing such as a morse "S" is achieved. Lack of current in the lamp circuit when a voltage is applied thereto actuates a lamp changer 16 (see Division H3) which may be of the type which moves a selector switch 20 from lamp 11C to lamp 11B.

Abstract: The needles of a parallel bed machine are composed of two components, the hook portion 1 which slides in the trick of the needle bed 21 and a point portion 10 which slides in the trick in a bed 29 opposite that of the needle bed as illustrated in Fig. 9, not shown.  The hook portion 1, Fig. 2 not shown, and the point portion 10, Fig. 6 not shown, are of complementary configuration such that their cooperative function and manipulation permits a new yarn to be drawn into loops n1 by the hook portions 1 Fig. 12, not shown, whilst the old loops o1 are cast off over the hooks onto the shanks of the point portions. Subsequently the point portions are withdrawn to separate the two portions and the old loops are released to extend over the backs of the needles.  When it is desired to transfer loops to needles on the same bed the point portions are lowered to cooperate with the hook portions and receive the loops whereupon they are raised by a catch bar 32 and deflected outwardly by a bar 17 Fig. 16, not shown.  The needle bed is then shogged and the point portions thereafter lowered to return the loops to the hook portions.  When it is desired to transfer loops from the needles of one bed to the needles of the other bed the point portions take the loops from the hook portions whereupon the opposite needle bed is shogged half a needle space to align its needle hook portions with the loops to be transferred whereafter these hook portions are advanced to take the loops and the point portions retracted to release them.
