Abstract: 1,168,209. Semi-conductor devices. TOKYO SHIBAURA ELECTRIC CO. Ltd. 7 March, 1968 [9 March, 1967], No. 11183/68. Heading H1K. In a transistor the emitter connecting wire 61 linking the emitter electrode to the emitter terminal lead 57 is less than half as long as the base connecting wire 62 or 63 linking the base electrode to the base terminal lead 58, thereby reducing the emitter inductance. The transistor element may be mounted with its collector electrode in direct ohmic contact with a metal header (10), Fig. 1 (not shown), the emitter and base connecting wires (20, 21) being joined directly to the corresponding terminal leads (13, 14), which extend through insulated apertures (11, 12) in the header (10). Alternatively the element 60, Fig. 6, may be mounted on an A1 film 56 on an insulating substrate 52, e.g. of beryllium oxide, carried by a Cu support 50, a collector terminal lead 59 also being attached to the film 56. As shown, the emitter and base connecting wires 61, 62/63 are joined to further A1 films 54, 55 which respectively carry the emitter and base terminal leads 57, 58, but the films 54, 55 may be omitted, in which case the wires 61, 62 are connected directly to the terminal leads 57, 58. The second base wire 63 is also omitted in the last-mentioned embodiment.

Abstract: 288,985. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). April 16, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 17, 1928]. Benzanthrone derivatives.-Benzanthrone-peridicarboxylic acid, its derivatives and substitution products, are obtained by treating 4- benzoyl-1 : 8- naphthalic acid or its anhydride, or a derivative or substitution product thereof, in presence or absence of a, diluent or fluxing agent, with a metal chloride having a condensing action, e.g. aluminium chloride, sodium aluminium chloride, or ferric chloride, either alone or in presence of an oxidizing agent, e.g. molecular oxygen or manganese peroxide. The treatment of 4-benzoyl-1 : 8-naphthalic acid or its anhydride with alkali-aluminium chloride whilst introducing oxygen or a gas containing free oxygen (see Specification 293,768) is excluded. The derivatives of 4-benzoyl-1 : 8 naphthalic acid which may be used include the compounds obtained from the anhydride by reaction with ammonia or a primary amine or o-diamine. According to examples, (1) benzanthrone-peri-dicarboxylic acid and its anhydride are obtained by fusing 4-benzoyl-1 : 8- naphthalic anhydride with aluminium chloride, (2) chlorbenzanthrone - peri - dicarboxylic anhydride is obtained by fusing 4-p-chlorbenzoyl- 1 : 8-naphthalic anhydride (made by oxidizing 5- p-chlorbenzoylacenapthene) with a mixture of anhydrous aluminium and sodium chlorides with addition of pyrolusite, (3) 4-benzoyl-1 : 8- naphthalic-N-phenylimide (obtained by condensing 4-benzoyl-1 : 8-naphthalic anhydride with aniline) is converted into benzanthrone-peri-dicarboxylic-N-phenylimide by fusion with sodium aluminium chloride; the imide and N-methylimide of 4-benzoyl-1 : 8-naphthalic acid undergo a similar reaction, (4) 4-benzoyl-1 : 8-naphthoylenebenzimidazole (obtained by condensing 4-benzoyl- 1 : 8-naphthalic anhydride with o-phenylenediamine) is fused with sodium aluminium chloride while introducing oxygen; the product dyes cotton from the vat in brilliant orange-red tints, and (5) 4-benzoyl-1 : 8-naphthoylene-1: 2- naphthyleneimidazole (obtained bv condensing 4- benzoyl-1 : 8-naphthalic anhydride with 1 : 2- naphthylenediamine) is fused with sodium aluminium chloride; the product dyes cotton from the vat in fast brown tints. The Specification as open to inspection under Sect. 91 (3) (a) contains an additional example in which benzanthrone-peri-dicarboxylic acid and its anhydride are obtained by fusing 4-benzoyl-1 : 8- naphalic anhydride with potassium aluminium chloride while introducing oxygen.

Patent GB-166969-A (GB)
Title: Improvements in and connected with gas producer plant and gas engine plant supplied therefrom
IPC: C10J3/30
Filed: 1920-04-24
Abstract: 166,969. Read, H. J., and Bransom, W. J. April 24, 1920. Charging.-In a gas-producer plant the fuelsupply arrangement comprise a mechanical feeder j and a double valve-device c, d, the latter or both of which are controlled, in accordance with the working of a gas engine supported by the plant. As shown, an electromotor 12 drives, through gearing 15, 16, ratchet wheel 21, and sprocket chains 22, t, a pair of discs q, q<1> carrying strikers s, s<1> for operating the valves c, d in succession, and a pinion u geared to the feeder j. A spring-controlled flap l limits the amount of fuel carried in the pockets k of the feeder, but yields to allow the passage of protruding lumps. The feed is effected at the desired rate by controlling the motor 12 from an electricity meter, which measures the output of a dynamo driven from the gas engine. The meter drives a cam z Fig. 2, which closes at intervals the circuit 8 of a relay switch 9. The closing of this switch completes the circuit of an auto-starter 11 for the motor 12 and also energizes a coil 13 which holds the switch 9 closed after the circuit 8 has been broken by the cam z. The motor now operates, and after a complete feeding operation has been effected, the striker s closes a contact 23 and short-circuits the coil 13, thus allowing the switch 9 to open and stop the motor. Alternatively, the feeding-mechanism may be driven directly from the engine, or may be controlled by a meter measuring the gas output of the producer, and apparatus for starting the fuel, reciprocating the grate bars, &c. may be operated from the same source as the fuel feeder. An endless conveyer may be used instead of the pocketed-drum feeder j, and the valves c, d may be operated in the desired sequence by a reciprocating rod carrying a pivoted striker.

Abstract: 527,980. Cathode-ray tubes. PEARCE, A. F. April 18, 1939, No. 11658. [Class 39 (i)] The anode of a cathode-ray tube is supported on one end of a tubular insulating member, the other end of which is attached to the end of the tube, so as to lengthen the leakage path between the anode and other electrodes. Fig. 3 shows an anode 1 secured to the tubular member 5 by means of flange 9 of a suitable intermediate sealing material. The member 5 may be made of sections of materials suitable for sealing to the flange 9, the wall of the tube, and for uniting the two other portions. The member 5 is shown as sealed to the tube at a point well beyond conducting elements outside, such as deflecting and scanning coils. A portion of the member 5 may be metallized and serve as a second anode. The tube may be formed with depresssions 13, as described in Specification 507,840, which serve to hold a jig for fixing the anode while the member 5 is being sealed to the tube. The member 5 may be formed as a continuous tube, or as a ring of arms.

Title: Improvements in devices for actuating at least one member in accordance with the moisture content of runs of material
IPC: G01N27/22
Filed: 1946-04-16
Abstract: 610,788. Electric indicating systems. COURVOISIER, F. April 16, 1946, No. 11712. Convention date, April 17, 1944. [Class 40 (i)] [Also in Groups XXXV and XXXVI] In a device for actuating at least one member in accordance with the moisture content of a moving strip of material, an electrostatic potential is developed, by friction, on the strip, which is converted to A.C. by application to a periodically varying condenser and applied after amplification to control the said member. In the embodiment shown, the fabric strip 21 passes under a system of collectors which are electrostatically charged by friction to a degree dependent upon the strip moisture content. Electrical connection by wire 20 is made from the collectors to one plate of variable condenser 23. The instantaneous spacing of the plates of condenser 23 is varied periodically by electromagnetic driving device 24 after a mean spacing has been arranged manually and the resulting A.C. current through the condenser passes to earth through the resistor 25. A voltage proportional to this current is tapped from grid resistor 25, is amplified in valve 27 and rectified by the incorporated diode, the anode 28 of which energizes the control grid of valve 32. The valve 35 is controlled through its grid, from the potentiometer 37 across the D.C. supply from double diode rectifier 22, and its bias thereby adjusted to correspond to a datum moisture condition of the fabric, indicated by a zero reading on meter 36. When the fabric moisture content changes, the bias on the grid of valve 32 alters accordingly, the anode currents of valves 32, 35 no longer balance and the meter 36 reads correspondingly. Valves 38, 39 driven from valves 32, 35 operate relays 40, 41 which cause signalling lamps 43 to light to indicate the fabric moisture content and an adjusting device to maintain the moisture content stable.
