Title: Apparatus for the Automatic Calibration of Digital Instruments.
Inventor: LOWE PETER ROBERT
IPC: H03M1/10
Filed: 1966-08-02
Abstract: 1,172,830. Calibrating digital voltmeters. SOLARTRON ELECTRONIC GROUP Ltd. 26 July, 1967 [2 Aug., 1966], No. 34646/66. Heading G4H. A digital instrument 10, e.g. a voltmeter is automatically calibrated for a given value in response to a command input signal applied to a bi-stable 11 by testing the output of the instrument in a logic gate 14 to determine whether it is equal to or differs from the given value, the output of the gate 14 being used to adjust the instrument until it gives the correct output and thereupon to reset the bi-stable 11 so that the instrument is set for normal operation or a further calibration operation is initiated. As described, the given value is zero, the input terminals of the voltmeter being short-circuited and the gate 14 being set to respond when all the inputs are "0." If any of the inputs are " 1 " the inverter 15 passes a signal to gate 16 to signify that a correction is necessary. Another input is from bi-stable 11 and the third from the " adjust-command " output 25 of the voltmeter 10 through capacitor 26 and delay 17. Gate 16 passes a pulse to gates 18, 19, one of which is open according to the sign of the reading of the voltmeter. A motor 20 is controlled by the open gate to move a step in the appropriate direction adjusting potentiometer 21 to reduce the error. The meter gives a succession of command signals, one at each change of reading, until the gate 14 indicates that all the inputs are " 0." At this moment gate 23 is enabled and the next command signal resets bi-stable 11 so that normal operation can take place. Or if calibration at another value is to be made this is initiated by the resetting of bi-stable 11.

Title: Multiplex parallel commutator windings for commutator machines
IPC: H02K23/36
Filed: 1947-12-30
Abstract: 650,749. Winding layouts for dynamoelectric machines. MORAVIAN ELECTRICAL ENGINEERING WORKS, and KLIMA, V. Dec. 30, 1947, No. 34649. Convention date, Sept. 27, 1946. [Class 35] A multiplex commutator winding is composed of a series of simplex windings placed on axially separated parts of the armature and interconnected so as to provide a continuous series path from one commutator segment to another. In its simplest form, Fig. 1, a duplex parallel winding consists of two lap windings a, b, c, d, &c. and a<SP>1</SP>, b<SP>1</SP>, c<SP>1</SP>, d<SP>1</SP>, &c. wound on axially-separated cores and joined at their end connections 1<SP>11</SP>, 2<SP>11</SP>, &c. Commutators with interconnected brushes may be connected at both ends as indicated or one may be omitted without substantially altering the current distribution in the windings. In a modification, Fig. 4, the conductors pass straight from one core to the other and are joined by interconnectors s to produce the same electrical effect. If desired, these interconnectors need not be joined to the main conductors but have special leads passing through the same slots to the commutator segments at either end. Combinations of lap and wave windings may be used and the simplex windings may be both equal to a pole-pitch or one may be of greater and the other less span. A triplex winding having three armatures is illustrated.

Title: Improvements in or relating to means or apparatus for locking and unlocking the doors of railway coaches and the like
IPC: E05B65/36
Filed: 1922-12-20
Abstract: 210,935. Jackson, R. C., and Parker, L. S. Dec. 20, 1922. Pneumatically - operated fastenings.-In railway carriage door fastenings operated simultaneously by air-pressure or vacuum acting on a piston carried by a rod, one end of the rod forms the bolt and the other end a hand-releasing means, and the piston has a retracting spring on one side of it and a buffer spring on the other for retaining it in the mid position in the cylinder. The rod f carrying the piston d slides in stuffing boxes in the end caps b of the cylinder a which is secured to the carriage. One end of the rod forms the bolt and engages the socket r on the door s. The bolt is normally held retracted by a spring g, and a spring h at the other side of the piston acts as a buffer to keep the piston in its mid-position in the cylinder. Compressed air may be admitted behind the piston by the pipes l<1> from the guards van or engine cab to shoot the bolts. Or air may be exhausted from before the piston by pumps in connection with the pipes l. A three-way cock controlled by the guard or engine-driver enables the vacuum to be destroyed or the air-pressure removed to allow the bolts to be retracted by their springs g. If these springs fail to act, the bolts may be withdrawn by the handles t. Breakage of the pipes l, l<1> result in withdrawal of the bolts. Cocks k may be provided to disconnect any bolt or bolts from the pressure supply. Both pipes l, l<1> or either only may be used with each bolt.
Patent GB-347614-A (GB)
IPC: C06F1/12
Abstract: 347,614. Filling match boxes. WADE, H., 111, Hatton Garden, London.-(Compania General de Fosforos Sud- Americana Soc. Anon. ; 309, Calle Cangallo, Buenos Aires.) Oct. 23, 1929, No. 32120. [Class 94 (i).] Relates to machines for filling match boxes of the slide and shell type or of the type in which the inner and outer parts are held together by a rubber ring &c. The matches are introduced into the machine between laths disposed between guides a, Fig. 3, after removal of the matches the laths are removed by a transporter c to guides b, into which they are introduced by vertical plungers, and through which they are conducted out of the machine. A rail d, carrying a series of tubular members v, is moved so as to receive the matches and is then given a horizontal reciprocating and tilting movement so as to deliver them to a series of shoots e. The matches are tilted from the members v by the upward movement of a member r. The matches slide down the shoots e until they arrive in a series of shoots f, down which they are pushed in a reverse direction by plungers into boxes arranged on a rotating table h or an endless conveyer. The process. is repeated until the boxes are full. The boxes are fed into position by slides m, Fig. 4, in a closed state, and are opened by mechanism diagrammatically indicated at n. If the boxes are of the slide and shell type, the mechanism comprises slides to push the slides partly out of the shells, and if the boxes are of the type in which the parts are held together by rubber rings &c., the mechanism comprises pincers which grip and withdraw the inner part. Further movement of the conveyer h carries the opened boxes into position in respect of the shoots f. After filling, the boxes arrive in front of closing mechanisms o, which also expels the boxes through delivery openings p. When the conveyer h is replaced by a rotary table, the various mechanisms are arranged circumferentially round the table.

Abstract: 1396253 Brake-lining wear alarms SUMITOMO ELECTRIC INDUSTRIES Ltd 20 July 1973 [24 July 1972] 34811/73 Heading F2E A brake-lining-wear sensing circuit of the type having a detector circuit comprising an electrical conductor 22, 24, 26, Fig. 1, arranged to be broken when the lining 18 or 20 wears down to a predetermined limit, includes the following: voltage-divider means 28, 36 connected to a D.C. power source 34, a negativeresistance diode 32, which is normally non- conducting, connected to a tapping of the voltage divider means, and means (e.g. part of conductor 22) connecting the conductor in series with the voltage divider means and within a detector circuit shunting the diode; the component values of the sensing circuit are so related to the supply voltage 34 that when the detector circuit is (as normally) uninterrupted, the divided voltage applied to the diode 32 is less than its threshold switching voltage but greater than its holding voltage; when the detector circuit 22, 24, 26 is interrupted, even only momentarily, the threshold switching voltage across the diode 32 is exceeded, so rendering it conducting, and it remains conducting; the diode itself may in its conducting state act as an alarm indicator, (see below), but, as shown in Fig. 1, a separate indicator 30 such as a lamp, buzzer or luminous diode is incorporated. In Fig. 2 (not shown), resistance 28 is replaced by the alarm indicator 30 whose internal resistances therefore acts as part of the voltage divider, the other resistance 36 then being chosen to produce the appropriate voltage across the diode 32. Fig. 3 (not shown) resembles Fig. 1, except that diode 32 and alarm indicator 30 are combined in the form of a light-emitting diode having negative resistance (40). Since any breakage in the detector circuit activates the alarm, the arrangement is failsafe.

Title: Process for the preparation of hydrogen peroxide
IPC: C01B15/01
Filed: 1955-12-06
Abstract: <PICT:0786237/III/1> In the anodic oxidation of sulphuric acid or a sulphate and decomposition of the anodicallyformed persulphuric acid or persulphate to porduce aqueous hydrogen peroxide, the cathodically-formed hydrogen is converted into aqueous hydrogen peroxide in relatively dilute solution by known method.  As shown, anodically oxidized solution, e.g. containing 32 per cent persulphuric acid, flows through line 13, preheating column 14 and steam distillation column 15.  Residual sulphuric acid is returned to the electrolysis process while steam containing, e.g. 7-10 per cent hydrogen peroxide is passed via line 16 into fractionation column 17 in countercurrent to a dilute solution of hydrogen peroxide produced in known manner from cathodic hydrogen from line 116.  Hydrogen peroxide of, e.g. 35 per cent strength is withdrawn through line 18 while steam is condensed in condenser 19.  The steam may be used to preconcentrate the dilute solution of hydrogen peroxide produced from the cathodic hydrogen, and the condensed steam returned to the electrolysis process.  The cathodic hydrogen may be converted to hydrogen peroxide by catalytic or silent electric discharge oxidation; reduction of cadmium hydroxide, amalgamation of the resulting cadmium with mercury and reaction of the amalgam with water in the presence of oxygen; successive reduction and reoxidation of 2-methyl-anthraquinone or azotoluene.  Specification 735,195, [Group XXXVI], is referred to.

Title: Manufacture and treatment of woven cloth
Inventor: EWEN IAN ELRICK
IPC: D21F1/00
Filed: 1962-09-14
Abstract: 984,503. Making wire fabric. UNITED WIRE WORKS Ltd. Sept. 5, 1963 [Sept. 14, 1962], No. 35049/62. Heading B3A. [Also in Division D1] A method of treating woven cloth for forming into endless belts for papermaking machines comprises forming throughout the length of each warp a series of stretched chevronshaped formations transversely directed in the plane of the cloth. Contiguous lengths of cloth may be successively treated by tensioning each length of cloth, clamping it at each end and midway between its length and applying a force transversely in the plane of the cloth to the intermediate clamped portions so as to displace the warps of the length of cloth, and subsequently stretching the length by moving the clamped ends further apart. Alternatively the warps of successive lengths may be angled out of the straight in one direction and stretched and then in the other direction. Further, a series of cloth lengths may be treated simultaneously. In Fig. 4 cloth 15 is unwound from roll 12 and after treatment is taken up on roll 14. After a length of cloth has been fed through the apparatus, front clamp 9 is operated by hydraulic ram 22 to clamp the cloth between jaws 9A and 9B. The cloth is then tensioned by driving the coiling roll 14 and the rear clamp 11 is operated by its ram 22 to clamp the cloth between jaws 11A and 11B. The middle clamp 10 is then operated through ram 37 to clamp the cloth between jaws 10A, 10B and the clamp 10 is moved transversely by hydraulic ram means (not shown in Fig. 4) on rollers 38, 39 so as to displace the warps into chevronshaped formation and the cloth is then stretched longitudinally by moving the clamps 9 and 11 further apart by pivoting them about pivots 23 through the medium of hydraulic rams 24, vertical slides 25 and pivoted levers 26. The clamp 10 is then released and the cloth is further tensioned longitudinally by moving clamps 9 and 11 slightly further apart. Clamps 9 and 11 are then released and the roll 14 driven to take up the treated length of cloth and replace it in the apparatus by the next successive length. The apparatus may alternatively have only two clamps arranged to treat the halves of each length successively or there may be a relatively large number of clamps, every second clamp being movable transversely so that several successive lengths of cloth may be treated simultaneously. Heating means may be incorporated for treating cloth having warps and/or wefts of copper berillium alloy or for setting, if the cloth incorporates synthetic resinous material.
