Title: Timing circuit for defining long intervals of time
IPC: H03K17/58
Filed: 1962-01-12
Abstract: 961,846. Semi-conductor delay circuits. STANDARD TELEPHONES & CABLES Ltd. Jan. 12, 1962 [Jan. 19, 1961], No. 1217/62. Addition to 961,844. Heading H3T. A timing circuit comprises a monostable trigger and a chain of tunnel diodes in which an input pulse changes the state of the monostable trigger. The trigger then reverts to its initial state after a predetermined time, and switches one of the tunnel diodes, the voltage change across the tunnel diode being effective to switch the trigger back to its second state. In a first embodiment, Fig. 2, application of a negative trigger pulse to the base of transistor Tr1 renders it conductive cutting-off transistor Tr2 and setting all the tunnel diodes TD1 ... TDn into their low voltage state. After a time determined by the time constant of capacitor C and resistor R, Tr1 cuts-off and Tr2 again conducts switching one of the tunnel diodes after a delay due to the inductance of relay Re1. Switching a tunnel diode produces a pulse via capacitor Ck which re-triggers Tr1 and the cycle repeats until all tunnel diodes are in their high voltage state. The circuit then resets to its normal state with Tr2 conducting and the relay operates. In a second embodiment, Fig. 3, re-setting of the trigger circuit is effected via a feedback circuit including a transformer with windings W1, W2. Application of a positive control pulse to E cuts-off transistor Tr2 and capacitor C starts to discharge. Diode D is held cut-off during this discharge, but as soon as reverse charging commences diode D conducts completing the circuit for the winding W1 and the feedback process is initiated. Fig. 4 shows a further modification in which the control pulse is applied for the entire interval of the delay, and in which an output signal only appears after the delay period. Under normal conditions the feedback path through diode D3 is blocked, and both transistors are cut-off. Application of a positive input pulse at E cutsoff diode D5 and switches transistor Tr1 on, to discharge capacitor C to switch Tr2 on. This switches one of the tunnel diodes to produce a pulse which resets the circuit as before. Specification 901,845 also is referred to.

Title: Improvements in and connected with flooring construction
IPC: E04F15/22
Filed: 1934-01-13
Abstract: 430,513. Floors. BENNETTS, J. H., Carisbrooke, The Grove, Finchley, London. Jan. 13, 1934, No. 1284. [Class 20 (iv)] A floor is carried on supports by which various portions of the floor are intercoupled so that depression of one part of the floor under load necessitates a simultaneous elevation of one or more other portions. The joists 5, Fig. 1, may be mounted on rocker bars 1 which are formed with central bosses 2 supported on leather, rubber, asbestos or like pads 8 on the floor foundation. The ends of the bars 1 are flanged for bolting to the joists, and the bars may be arranged either diagonally between the joists or at right angles thereto. The pads 8 may be faced with soft material, such as white metal or lead. An alternative support for the bosses 2 consists of a saucer 12, Fig. 3, which is shaped to accommodate lubricant and may also be provided with a lining of anti-friction metal, felt, &c. Instead of providing a universal mounting for the rocker bars, a pivot adapted only to permit a simple rocking-motion may be provided. In some cases, both ends of some or all the rigid bars may be connected to the same joist. The rocker bars may be mounted either below or between the joists. In a further modification, adjacent joists 5 are carried on the shelf 18 of a bracket 17, Fig. 4, which is provided with a flange 19 carrying a depending plunger 20. The plunger 20 is connected with one branch 22 of an elbow tube, the other branch 23 of which extends towards the similar plunger assembly of an adjacent joist. The elbow tube accommodates a line of steel balls 24, and one end of the line abuts against a rod 25 sliding in a tube 26 extending between the adjacent plungers. The arrangement shown in Fig. 4 may be adapted for hydraulic operation, one hydraulic plunger being then interconnected, if desired, with several other similar assemblies so that the motion of one plunger is distributed uniformly or not, according to circumstances, between the other plungers. The joists 5 may be anchored to the foundation by clips 10, Fig. 1, which are of the kind described in Specification 395,835.

Abstract: 994,967. Television; limiters. MARCONI CO. Ltd. Nov. 1, 1961 [Jan. 13, 1961], No. 1521/61. Headings H3W and H4F. A clipping circuit comprises a pair of diodes connected in series opposition between the input and output terminals, the voltage at the junction of the diodes being inverted and passed by a cathode follower to the output terminal. In Fig. 1 the D.C. level of a television waveform at the grid of a cathode follower V1, is clamped to the voltage at the slider of RV1 under control of pulses fed to diodes D1, D2. RV1 is adjusted so that the clipping diode D3 is conductive during the negative-going video waveform but non-conductive during the positive-going synchronizing pulses. The video waveform is inverted by V3 and passed by a cathode follower V2 to the output line. Diode D4 is conductive during the time D3 is non- conductive, the changeover of conductive states of the diodes being made more definite by the effect of the inverted waveform from V3. The clipping level is adjustable by variation of RV1 or RV2. V3 and V2 may be coupled via a direct current path. In Fig. 3 (not shown) the loading on cathode followers V1, V2 is made constant by a further pair of diodes connected in series opposition across D3, D4 but with reversed polarity.

Abstract: 918,039. Control of A.C. motors. LEEDS & NORTHRUP CO. Jan. 13, 1961 [Feb. 5, 1960], No. 1606/61. Class 38 (3). [Also in Group XXXV] In a control system for an alternating-current motor 40, employed in an automatic furnace pressure control system (see Group XXXV), a line L1 of the supply is directly connected to a motor terminal M1 and the lines L2, L3 are connected to terminals M2, M3 through the primaries of transformers 85-88 connected as shown. The secondaries of the transformers are connected in series across thyratrons 76A, 76B, normally biased non-conductive so that in the absence of a grid-control signal the motor does not rotate. When a control signal is applied to a primary of a transformer 77B, the thyratron 76B is rendered conductive to shortcircuit the secondaries of transformers 87, 88 and connect the terminal M2 to line M3 and terminal M3 to line L2 to cause the motor to rotate in one direction, and conversely, when thyratron 76A is conductive the terminal M2 is connected to line L2 and terminal M3 to line L3 so as to rotate the motor in the other direction. For a three-terminal single-phase motor one pair of saturable transformers are employed and the conduction of a thyratron determines which pair of motor terminals are energized. U.S.A. Specification 2,797,291 is referred to.

The loaded carriage circulates paths 10, 20 until an unloaded carriage is available. Assume a carriage is indexed at station 13 for station 33, as the carriage approaches points 18 the index mark is read and operates contacts 311 whereby an input is applied to AND gate 322. If an unloaded carriage is available in storage track 34 a contact 36 is operated and applies a second signal to the AND gate via mono-stable circuit 321. The output signal from the AND gate 322 is applied via terminal 305 to a mechanism 35 which releases the unloaded carriage from track 34 and also to a bi-stable circuit 329 which on changeover applies a signal via an OR gate to set points 18 for path 30. When the carriage has passed over the points contact 16 operates and restores the bi-stable circuit 329 and the points to normal. The arrangement is dimensioned such that the distance between the points 18 and the junction of path 20 and 10 is equal to the distance between the release device 35 and the said junction so that the unloaded carriage occupies the space vacated by the loaded carriage routed to station 33. The indexing arrangement now operates a relay device 37 which sets points 38 for the path 30.
