Title: Improvements in or relating to electric pulse forming circuit arrangements employingtransistors
Inventor: STEPHENSON WILLIAM LAWRENCE
IPC: H03K17/60
Filed: 1954-10-06
Abstract: 763,749. Transistor pulse circuits. MULLARD RADIO VALVE CO., Ltd. May 24, 1955 [Oct. 6, 1954], No. 28789/54. Class 40(6) In a circuit employing a transistor T with a gain less than unity, a load 2 is arranged in the emitter-collector path, the supply potential E being reversible so that the pulses applied to the base can be inverted as desired. The transistor T, Fig. 1, is preferably a symmetrical junction type and with a negative supply potential operates as an earthed collector amplifier. With a positive supply potential, Fig. 2, the transistor T operates as an earthed emitter amplifier so that the output is reversed in sign. Since there is no D.C. bias applied to the transistor the output pulses operate from a level near earth potential. The switching wave form does not therefore appear in the output (Fig. 3, not shown). As the transistor T is driven from cut-off to the fully bottomed condition the positive and negative supplies are preferably equal. In a modification, Fig. 4, a low output impedance comprising an inductor 12 is employed the base being suitably biased by resistors 13, 14 so that the circuit will accept both positive and negative pulses. The supply circuit may be a mono-stable switching circuit having a reset interval corresponding to the periodicity of one pulse of the train. A synchronizing circuit is provided to prevent reversal of the potential occurring near the time at which a signal pulse is expected. When an inductor 12 is employed the rate of change of the switching potential must be sufficiently low to prevent the generation of spurious pulses.

Abstract: 1,216,249. Moulding pulp slurries. FIBERS Inc. 18 June, 1968 [5 July, 1967], No. 28941/68. Heading B5A. Fibrous articles are moulded from pulp slurries in water employing foraminous die assemblies 40 which are sequentially displaced on to a perforated table 10 covered with a perforated flexible cushion 35; a deckle 50 is lowered to sealingly rest on the marginal walls 42 of the die 40 and pulp slurry is introduced, via a valve 60, to be diffused over the die 40 by a diffuser 64 until the die is covered; fluid is then withdrawn to deposit pulp on the die 40 by the application of vacuum through the die 40 and table 10, via a valve 30; the deckle 50 is then raised and is subsequently lowered to clamp over the die 40 a thin rubber membrane 76 which has bean unwound from a spring return roller 74 by a ram-actuated frame 70. Continued application of vacuum draws the membrane 76 into pressure applying contact with the pulp deposit on die 40 whilst fluid withdrawal therefrom is simultaneously continued; the deckle 50 is then raised and the blanket 76 stripped from the die 40 by a peeling action obtained by maintaining the vacuum during retraction of the frame 70. In an alternative method of charging the deckle 50 with pulp, water is initially admitted thereto from the underside of die 40 to the level WL, via a valve 28; pulp is then introduced into the water through valve 60 to the level FL, whereby the pulp is diffused through a greater quantity of water to enhance the uniformity of deposition thereof on the die 40. The die 40 with the pulp deposition thereon is displaced on to rollers 47 by the next advancing die 40 and the pulp layer either air dried on the die or by passing the die through a hot air stream oven. The shaping element of the die 40 comprises a Fourdrinier screen.

Abstract: 1,108,422. Weighing apparatus; measuring weight. COAL INDUSTRY (PATENTS) Ltd. July 9, 1965 [July 14, 1964], No. 28987/64. Headings G1N and G1W. A method of feeding two or more materials to a blending position T to form a blend of predetermined bulk density comprises feeding the materials, one of which has a constant bulk density or a continuously monitored bulk density, to the blending position and adjusting the feed rate of at least one of the materials in relation to the bulk density or a property related to bulk density thereof so as to obtain the required blend. As shown, material D 1  which may have a constant bulk density is fed from a hopper E 1  to a constantly rotating conveyer belt U which may be constantly driven and which leads the material D 1  to the blending position, a further material D having a varying bulk density being fed from a hopper E to a pivotally mounted conveyer belt A which is driven by a drive roller B at a rate proportional to the weight of a constant volume of material D on the belt A. The weight of material is sensed by a diaphragm J which is connected through a valve K either to fluid supply or to fluid exhaust lines M, N respectively and which supplies a fluid signal to a device P which suitably adjusts the drive of the roller B, further signals being supplied to the device P over a line Q if the bulk density of the material D 1  or the rate of rotation of the conveyer U is not constant. In an alternative embodiment Fig. 2 (not shown), the weight of one of the materials being fed by a conveyer belt is sensed by a pneumatic, hydraulic or electrical member (S) underlying the belt.

Abstract: 1,098,896. Telegraphy. SIEMENS A.G. June 29, 1966 [June 30, 1965], No. 29160/66. Heading H4P. In a telegraph exchange system comprising channels a combination of which is marked simultaneously by each serial bit, the combination being characteristic of a receiver or transmitter, a plurality of connector sets is provided, each of which can be set to receive from one combination of channels and to transmit on another combination. When a subscriber Tn1 wishes to transmit to a subscriber Tn100 he causes central unit ZES to seize a free connector set VS1-VS20 and to set the seized unit to receive at KE data from a combination of lines characterizing the calling subscriber and to transmit from KS that data on a combination of lines characterizing the called subscriber. Each subscriber Tn1-Tn100 is connected to a corresponding subscriber circuit TS1-TS100. Each subscriber circuit transmitter, e.g. KS1, is connected by two lines to a unique decimal combination of lines in multichannel line SV. The decimal combination is converted to excess-3 form by unit UCS for transmission on multichannel line KV and passes to the selected connector set VS1- VS20. From this the data passes, in excess-3 code characterizing the called subscriber, to unit UCE where it is converted to decimal form. The data then passes over multichannel line EV to the subscriber circuit receiver KE100 and so to the subscriber Tn100.

Abstract: 534,751. Cellulose ester compositions. HERCULES POWDER CO. Nov. 6, 1939. No. 29508. Convention date, Dec. 24, 1938. [Class 2 (ii)] A cellulose acetate moulding composition of improved colour stability on heating at moulding temperatures is obtained by adding an acid to the composition in an amount sufficient to retard discoloration of the composition but insufficient to have any deleterious effect, i.e. in an amount within the range of about 0.002 per cent. to 0.10 percent. by weight of the cellulose acetate. The acid used may be phosphoric, nitric, oxalic, citric, tartaric, or lactic acid. The composition may contain plasticizers such as camphor, dimethyl phthalate, diethyl phthalate, diphenyl phthalate, ethyl phthalyl ethyl glycollate, tricresyl phosphate, tributyl phosphate, butyl tartrate, triacetin, o- or ptoluene sulphonamide, tripropionin, triethyl citrate, dimethoxy ethyl phthalate, methyl methoxy-ethyl phthalate, sorbitol hexa-acetate, or a plasticizing resin. The composition may contain a pigment or a dye. The acid ma,y be added at any stage in the preparation of the moulding composition prior to the moulding operation itself. In an example, cellulose acetate, dimethyl phthalate, acetone, and alcohol are mixed together and then passed through heated chrome-plated rolls: A small proportion of an alcoholic solution of oxalic acid is added, and the composition is subjected to further rolling till the volatile solvent is removed. The composition is then granulated and the moulding powder is moulded under heat and pressure. In another example, cellulose acetate, acetone, alcohol, and plasticizer are mixed together. A small amount of Milori Blue and Purple Blue Lake mixture is added, and then a small amount of an acetone solution of citric acid is added. The pastes or moulding powders produced may be used for the production of tubes, rods, sheets, or other articles.

Filed: 1946-10-03
Abstract: 623,418. Railway signalling apparatus. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Oct. 3, 1946, No. 29517. Convention date, Nov. 27, 1945. [Class 105] The presence of a vehicle in a stretch of track such as a section of railway or a single track highway or at a railway cross-over points is detected by the change in the capacity-to-earth of an insulated wire extending along the track such change in capacity affecting an electronic oscillator which energizes a detector relay. As shown, two insulated wires 1, 2 alongside the track are connected one 2 to one side of an oscillatory circuit L1, L2, C1 the other 1 to the grid of an electronic valve V1, the other side of the oscillatory circuit being earthed. The capacity between the insulated wires 1, 2 together with a variable condenser give an effective capacity C2 which with the capacity-to-earth of the insulated wire 1 denoted by dotted lines at X1 gives a divided-capacity voltage tap-off for application to the grid of the valve V1 ; the cathode voltage is applied from the point between the inductances L1, L2. The insulated wire 2 being at higher voltage shields the insulated wire 1 so that the capacity-to-earth XI of the latter is small with the result that the grid-cathode voltage is of a magnitude to cause oscillation. The presence of a vehicle increases the capacity value X1 which thereby reduces the magnitude 7 of the grid-cathode voltage to stop oscillation. The detector relay R is energized from the oscillatory circuit through a tuned circuit L3, a valve V2 and tuned circuit L5. An arrangement is described, Fig.3 (not shown), in which after an operation to reverse and a restoration to normal of a railway cross-over points by a train crew a pointsnormal indication relay is not picked up until a detector employing insulated wires and electronic valve as above has been put automatically into operation and denoted no vehicle present ; thereupon the detector apparatus is automatically put out of action but the indication relay remains energized by a stick circuit.

Filed: 1953-10-27
Abstract: 740,179. Dynamometers. FOXBORO CO. Oct. 27, 1953 [Nov. 15, 1952], No. 29661/53. Class 106 (2). [Also in Groups XXIV and XXIX] A device for measuring a change in a variable condition comprises a member tiltable about a fulcrum which can be rotated to give a variable axis of tilt for the member, and a force indicative of the variable condition and acting in a direction substantially parallel to the axis of rotation of the fulcrum is applied to the member so that the latter tilts and transmits a signal corresponding to the value of the variable condition but depending on the setting of the fulcrum. In the application of the invention to a pneumatic control system, a ring 12, Fig. 1, is suspended by a spring 14 so that it can tilt in any direction about its axis 170. The ring is restrained, however, to a tilting movement around a fulcrum constituted by a strip 16 which can be rotated around the axis 170. A pressure corresponding in value to a variable condition is applied to a bellows 20 acting on the ring, and a pressure representative of a set-point or datum is applied to a bellows 22 acting at a diametrically opposed point on the ring. The ling acts as a baffle-plate controlling the escape of pressure fluid from a nozzle 34. Two further bellows 24, 26 acting on ring 12 at diametricallyopposed points give integral and derivative control effects, respectively. The fulcrum strip 16 can be rotated through 90 degrees to vary the proportioning band of the control system from 0 to 100 per cent, and its position is indicated on a scale 28. In a modification, bellows 22, 24 are replaced by loading springs. In a practical embodiment, spring 14, Figs. 8 and 11, comprises a cruciform member of which two opposed ends are screwed to ring 12, and the other two opposed ends are screwed to upstanding, fixed posts 174. The fulcrum member consists of a bar provided with apertures housing pairs of rollers 18 which run on the ring 12 and a thrust-plate 10. The invention is stated to be applicable to electrical and mechanical instruments. Specifications 591,270, 670,427 and 740,238, [all in Group XXIX], are referred to.
