IPC: G03G15/26
Abstract: 1,143,848. Electro-photographic apparatus. ADDRESSOGRAPH-MULTIGRAPH CORP., CHARLES BRUNING DIVISION. March 1, 1967 [March 4, 1966], No. 9639/67. Heading G2H. A photo-electrostatic copying machine comprises a copy sheet supplying section 22 for severing copy sheets of selected sizes from webs of light sensitive material, a corona discharge charging station 26; an exposure station 28; a developer station 30 and a fusing station 32. A pre-selected length of material is fed from one of two rolls 68, 70 differing width by rollers 76 or 78 to a severing station 72 at a speed faster than sheet driving apparatus 34, comprising belts 38, 40 and rollers 36, feeds the severed sheet away from the station 72. Hence when the web is stopped for severing after the required length has been unwound, the apparatus 34 continues to feed the sheet to the exposure station 28, where it is eventually halted for a full frame exposure of an original 56. After exposure, the copy sheet is propelled through the developing station 30 where finely divided electro-scopic particles are deposited thereon by a magnetic brush 60. The image is then rendered permanent by heat from a heating unit 62, and the finished copy ejected on to a tray 48. The above sequence is carried out automatically once the length and width of the copy sheet have been selected and the apparatus started. Selection of a sheet size also controls the operation of positioning means at the exposure station properly to position each sheet in accordance with its size. Several successive copies of the same original may be made automatically. Web-severing mechanism Figs. 7, 8 (not shown). This comprises a stationary cutter blade (122) and a blade (124) mounted for rotation into engagement with the blade (122) when the required length of web has been advanced between the blades, a spring (126) normally holding the cutter assembly in the inoperative position.

Abstract: 1,228,125. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 12 March, 1969 [19 March, 1968], No. 13030/69. Heading H4K. A telecommunication exchange class of service translator comprises a first store having locations individually associated with subscriber lines and each storing either a translation relating to its line or part of the address of a location in a second store at which the translation is to be found, and a third store used during a translation involving the second store to derive the remainder of the address from the line's number. The line's number may be a directory number or an equipment number. In one embodiment the stores are separate storage blocks Sp1, Sp2 and Sp3. Store Sp3 is stated to be a core store. The block Sp1 is accessed by the whole equipment number of a line and has a separate storage row for each line. Each row stores eight bits, i.e. a seven bit class of service translation or address and an index bit to indicate whether it is a translation or an address. Most rows store a translation as seven bits is sufficient to store the class of service of most lines. The rows associated with the maining lines each store part of the address of a row in storage block Sp2 storing a 32 bit translation. To give flexibility to the allotting of rows in Sp2, the remainder of the address of a row in Sp2 are derived from a store Sp3 having a 16 bit row location for each group of equipment numbers having say the same first three digits. The access circuit Z3 receiving these digits if an index check device JP detects a partial address in block Spl. The two partial addresses are combined at Add. A translation is given at an output K. In a second embodiment (Fig. 2, not shown) a single storage having 32 bit locations per row is used and rows used as stores Sp1 and Sp3 are divided into quarter and half rows respectively. A whole row is entered into a readout register and groups of AND gates are used to gate out a quarter, half or whole row as required.

Abstract: 1,238,554. Welding by fusion. D. SCIAKY. 15 April, 1969 [30 April, 1968], No. 19240/69. Heading B3R. [Also in Division H1] In electron beam seam welding, a beam is generated in an enclosed gun space at a high vacuum (e.g. 10<SP>-4</SP>-10<SP>-5</SP> Torr) and directed through an orifice 31 into an enclosed working space at a vacuum which is relatively low but sufficient to prevent oxidation (e.g. 100 microns), said working space being bounded in part by a section of the workpiece 20 on which the beam is focused (by an electromagnetic lens 16) and impinged. Prior to the electron beam welding, the workpiece plates to be welded are lightly arc welded together by a low-current sealing pass at 29 along the full length of the seam to be welded. The working space at the relatively low vacuum is sealed by a seal 19 and is surrounded by an annular space which is at the same low vacuum and is bounded by a further seal 18. The seals 19, 18 are circular or elliptical, are continuous and flexible (e.g. of silicone rubber), are supported in grooves of the gun carriage 32, and engage, and move relatively to, the workpiece. A space at the relatively low vacuum of the working space is also provided in a back-up fixture 21 which is sealed to the workpiece by a continuous seal 22 surrounding the back of the seam along substantially its complete length. As shown, the gun carriage 32 is provided with rollers 17 which may be guided by rails 33. The gun, working, annular and back-up spaces are evacuated by pumps P1 (not referenced) and P2-P4 respectively. The seam end edges and short end portions of opposite side of the seam are sealed with either a light arc welding pass or tape, the back-up fixture extending on to said short end portions. Where the electron beam welding is rough, a smooth sealing tape may be applied immediately behind the point of beam impingement, between said point and the seal 19. In Fig. 2 (not shown), in apparatus for welding a cylindrical butt joint of a tank, an outwardly directed gun is mounted on a rotating arm. An annular back-up fixture completely surrounds the outside of the seam and may be of the inflatable type so that, by deflation, it may be easily removed after the welding. In Fig. 3 (not shown), in apparatus for longitudinally welding plates, the gun is mounted on the end of a boom which is moved horizontally, for welding, by an electric motor, and vertically, for gun height adjustment, by screw jack.

Abstract: 1,265,060. Venting IC. engine fuel tanks . FORD MOTOR CO. Ltd. Aug.26, 1969 [Sept.3, 1968], No.42442/69. Heading F1B. Fuel vapour from a tank 26 and air from a conduit 74 are fed to the intake manifold 14 under the control of a valve 40. The valve member 46 is biased to a position blocking the communication between vapour and air inlet conduits 70, 74 and respective outlet conduits 77, 78 by a spring 68, the fuel vapour pressure and the vacuum downstream of the throttle valve 20 in chambers 64 and 88, respectively, acting against the spring bias. The spring bias is chosen such that the valve member 46 will open communication between the inlet and outlet conduits with idling vacuum in the chamber 88 and a predetermined vapour pressure, approximately ¢ p.s.i., in the chamber 64. The valve member 46 moves with increased vacuum in chamber 88 to abut stop 90 and close communication between the inlet and outlet conduits. Calibrated orifices 82 and 84 proportion the flow of air and fuel vapour through the conduits 74 and 70. The conduit 74 has an air filter 76.

Abstract: 1,265,883. Automatic gain control. PACIFIC PLANTRONICS Inc. 2 June, 1969, No. 27769/69. Heading H4R. A signal conditioner comprises a preamplifier 12 and a power amplifier 14 and connected between them is a signal attenuator 13, 18, 20 having a signal transmission characteristic which varies in response to an applied input signal. An amplifier detector 16 is connected to the preamplifier 12 for providing a control signal to the signal attenuator 13, 18, 20 to increase signal transmission therethrough when the signal at the output of the preamplifier 12 attains a selected value. Low level signals at the microphone 11 are amplified by preamplifier 12 and power amplifier 14. However, with low level signals, transistor 34 is conductive, but transistor 35 is non- conductive. Transistor 36 is conductive and high signal attenuation is provided by attenuator 13, 18, 20. As the signal level increases, transistor 34 becomes non-conductive and transistor 35 begins to conduct on half-cycles of alternating voice signals. A capacitor 75 then discharges and removes forward biasing at the base-emitter junction of transistor 36 after a few milliseconds. This renders the transistor 36 substantially non-conductive and reduces the attenuation provided by attenuator 13, 18, 20 after a brief delay. Thus, for input signals above a threshold, the apparatus provides substantially linear signal amplification at a higher gain level. The charging path for capacitor 75 is through a high resistor 73 and the charging time is sufficient to maintain transistor 36 non- conductive during syllable pauses.  Operating bias voltages at terminals A, B, C for the active elements are derived from voltages appearing on a pair of conductors to which the output terminals 81, 83 are connected. Germanium diodes 37 to 40 ensure a unidirectional biasing signal on lines 82 and 84 irrespective of the polarity of the feed current. The output impedance of attenuator 13, 18, 20 is higher than the normal input impedance of amplifier 14 and as the operating bias voltage on lines 82, 84 approaches low values the two impedances closely match, thereby increasing transfer efficiency and compensating for reduction of amplification of amplifiers 12 and 14. Similarly, the value of resistor 70 is higher than the normal input impedance of transistor 34 so that with decreasing supply current the closer impedance match increases transfer efficiency, thereby compensating for reduction in amplification of amplifiers 12, 14. The overall transmission characteristics are thereby maintained substantially constant over a large range of supply current values.
