Title: Electronic distributor
Inventor: SNIJDERS ANTONIE
IPC: H03K5/15
Filed: 1952-11-19
Abstract: 765,955. Thermionic distributers. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Nov. 19, 1952 [Nov. 24, 1951], No. 18199/54. Divided out of 765,953. Class 40 (3). The description is wholly included in Specification 765,953, and the claims are for an electronic distributer comprising an input tube and a number of distributer tubes having a common cathode resistor connected to the negative pole of a voltage source of which the positive pole is connected to the anode of the input tube and through resistors to the anodes of the distributer tubes, the anode of a distributer tube being connected by a capacitor to the control grid of the next tube and each distributer tube having between its anode and the negative pole of the voltage source a potentiometer provided with a tapping point connected to a separate conductor, and to ensure that solely one distributer tube is conductive at any instant, each conductor is connected by rectifiers to the control grids of all the distributer tubes, the potentiometer tapping points of which are not connected to the relevant conductor. The distributer comprises a circuit IV incorporating an input tube B4a and a tube B4b forming the first distributer tube and three circuits V1, V2, V3, each including two triodes, such as B5a, B5b and completing an array of seven distributer tubes. At any stage one only of the distributer tubes is conducting and assuming this to be B4b, the tube B4a is in a cut-off condition since all the cathodes are connected to a common resistor R4 and a negative voltage is applied from output terminal 4 of the tube B4b of circuit IV to the input terminals 8 or 5 of the other six tubes. When a positive pulse is applied at 8 to the grid of the tube B4a, e.g. from a multivibrator operating at 50 c.p.s., the tube B4a conducts and cuts off the conductive tube B4b which at its anode circuit produces a positive pulse applied from terminal 3 over capacitor C1 to the grid input 8 of the triode B5a, the first tube of V1, which conducts and cuts off the tube B4a of the circuit IV and also applies at output terminal 9 a negative potential to conductor 2 and via the connected rectifiers of the groups G5 ... G10, G11 ... G16, G17 ... G22, G41 ... G46 to the input circuits of all the other six distributing tubes. The arrangement provides a timed sequence of negative potentials on the conductors 1 ... 7, the potential at any time on the other six conductors being positive. Specification 572,884, [Group XL], also is referred to.

Title: Improvements in methods and devices for cutting sheet glass
IPC: C03B21/02
Filed: 1926-07-26
Abstract: 255,899. Reis, L. von. July 27, 1925, [Convention date]. Rolling.-Relates to a method of cutting hot, plastic sheet glass while it is resting on a travelling carrier, and consists in cutting the sheet above transverse gaps in the carrier by a blade which moves with the carrier and enters a gap when severing the glass. The sheet, formed by suitable rolling-apparatus, is received on tables a, Fig. 1, which run on rails and convey the sheet to the leer. Successive tables are separated by gaps h into which a knife blade b drops when cutting through the sheet. The blade b swings about, and is free to slide along. a shaft c which is mounted parallel with and to one side the track on which the tables a are mounted. The tables have rails m, Fig. 2, fixed to one edge, and a roller i carried by the blade b rests on these rails and holds the blade in its raised position. A coupling is also provided to keep the blade raised when the tables are out of position. In operation, the tables receive the glass sheet from the rolling-machine and pass below the blade b towards the right of Fig. 1. When the roller i falls through the gap between successive rails, the blade drops into the gap between the tables and cuts through the glass sheet. A stop g on the rail m carries the blade along with the table until a roller d, carried by the blade runs along a fixed cam e and raises the blade out of the gap. A counterweight f then draws the blade back along the shaft c to its initial position.

Title: Apparatus for weighing vehicles in motion
IPC: G01G19/04
Filed: 1965-05-04
Abstract: 1,108,982. Weighing loads in motion. S. H. LEVINSON. 4 May, 1965 [6 May, 1964], No. 18724/65. Heading G4H. Apparatus for weighing loads, e.g. railway trucks, whilst in motion includes means for determining the speed at which the load passes through the weighing station and indicating whether the speed is so excessive that the aocuracy of weighing is affected. In the embodiment described a relay Ra (Fig. 1) is engaged when a contact 3 at the weighing station is closed and it is held energized while there is a wheel on the,portion of the track 1d. When the relay de-energizes, i.e. when the truck is completely on the weighing portion of the track 1f, a pulse is applied on conductor 25 to a read logic circuit 39 (Fig. 2) and an output pulse from the logic circuit on conductor 40 resets a clock 43 to a preset value. The clock then counts to its maximum value when it generates a pulse on conductor 53 to a gate 45 which enables pulses on a conductor 54, the frequency of which represents the weight of the truck, to pass to a counter 52 where the count is displayed. The gate 45 whilst it is enabled by the signal on conductor 53 generates signals on conductors 61, 63, 64 until the clock 43 reaches a preset value and generates a pulse over conductor 60 to close gate 45. As the railway truck moves over the portion of the track 11 (Fig. 1) contact 4 is operated to energize a relay Rc and a pulse is then generated on conductor 32. If the signal on conductor 32 arrives whilst there is still a signal on conductor 64, i.e. is implying the train is approaching a speed at which the accuracy of weighing will be affected) a signal is generated on conductor 73 from marginal overspeed logic circuit 50 (Fig. 2) so that when a print impulse is received (when the clock 43 reaches a preset value) an AND gate 79 (Fig. 1a) is enabled to energize relay 12 and hence via contacts 12a, 13a, a yellow light 16 is lit and a motor 14 energized to drive a cam 19 to operate flasher contacts so that a horn 18 is sounded intermittently. When the railway truck moves on to the portion of the track 1g (Fig. 1) a relay Rd is energized and a signal transmitted on conductor 33 to an error logic circuit 51 (Fig. 2). If the signal on conductor 33 occurs whilst there is still a signal on conductor 63 (implying that the train was travelling too quickly) a signal is generated on conductor 75 so that when a printing signal occurs on conductor 81 an AND gate 83 is enabled to apply a signal to the printing mechanism on conductor 78 to indicate an error and an AND gate 82 is enabled which via conductor 101 energizes relays 10 and 13 so that via contacts 10a and 13b the horn 18 is continuously sounded and the motor 14 is energized to drive the cam 19 so that a red light 17 is flashed.
