Filed: 1963-09-20
Abstract: 1,030,449. Electrophotographic apparatus. RANK XEROX Ltd. Sept. 20, 1963 [Oct. 23, 1962], No. 37063/63. Addition to 887,232. Heading G2H. [Also in Division B6] In order to produce a plurality of prints from a developed electrostatic image on a xerographic plate the transfer of image particles on to copy material necessary for the production of each print is effected whilst subjecting the transferring particles to two corona discharge devices of equal electrostatic charge but of opposite polarity. As shown in Fig. 6 the developed image on a drum 40 is transferred at a transfer station 53 on to a web 59 corona discharge devices 58 and 60 used to provide a transfer charge and a neutralization charge, respectively, of equal but opposite polarity. The electrostatic image on the drum is thereby retained intact such that it is redeveloped by a developing device 52a prior to a further transferring operation on to a web 59a at a station 53a. Additional alternately arranged devices and transfer stations may be disposed around the drum in order to produce further prints or cleaning, charging and exposure stations 54, 50 and 51 may be removed from the vicinity of the drum to allow continuous rotation thereof whereby prints are continuously produced at the transfer stations 53 and 53a. Each corona discharge device is as described in Specification 826,088 the necessary equality of charge and opposite polarity for each associated pair being effected by the provision of a transformer rectifier circuit such as shown in Fig. 5 (not shown).

Headings H3T and H3W. In a direct current amplifier in which drift correction is provided the voltage to be amplified is applied via switch contacts 6, 5 and a cathode-follower 1, or transistor in emitterfollower connection, to one terminal of a capacitor 8. The other terminal of this capacitor is connected to the input of a direct-coupled amplifier 9, across whose output terminals is connected a potentiometer comprising resistors 13, 14. The tapping point of this potentiometer is connected to the moving contact of switch 15, the fixed contact of which is connected to the input of amplifier 9, and also to fixed contact 18 of switch 5. Resistor 14 is of small value. In operation, with the switches in the position shown, capacitor 8 is charged up, while the input to the amplifier 9 is to all intent short-circuited. The switches are reversed when the capacitor is fully charged, the input of the cathode follower 1 then being connected to the tap on potentiometer 14, 15 and the voltage at the second plate of capacitor 8 applied to the input of the amplifier 9. It is shown in the Specification that the resultant output from the amplifier 9 is an amplified copy of the input signal and independent both of drift in the amplifier and the difference of potential between grid and cathode of the cathode follower 1.

Title: Improved industrial burner apparatus and method of operating same
Inventor: EADIE GEORGE PATRICK
IPC: F23D17/00
Filed: 1966-08-24
Abstract: 1,149,389 Burners. LAIDLAW DREW & CO. Ltd. 22 Aug., 1967 [24 Aug., 1966], No. 38003/66. Headings F4B and F4T. In an industrial burner arrangement for furnaces such as soaking pits a first flow of pressurized air is passed axially through a tubular casing 4 surrounding an oil burner nozzle 17 and a second flow of pressurized air is simultaneously passed through a casing 7 feeding annularly disposed ports 6 so that the jets of air produced by the ports 6 impinge radially upon and at an angle to the axis of the first flow and the relative volumes of the two air flows are so controlled as to vary the length of the flame produced by the oil nozzle 17 or by gas fed through pipes 15. The relative air flows may be controlled by a single damper plate 10 operated by a power cylinder 42 in response to temperature operated controllers T1, T2. A main temperature controller 31 passes a signal to an air flow controller 26 which operates a damper 24 by means of a power cylinder 28 and at the same time the controller 26 operates an air/gas ratio controller 39 and gas controller 38, the system thus being such that if the air flow ceases the gas is cut-off. The soaking pit has an exhaust stack 22.

Filed: 1964-09-21
Abstract: 1,043,634. Conveyer systems; strikers and the like operating electric switches on the track. INVENTIO A.G. Sept. 21, 1964 [Sept. 30, 1963], No. 38346/64. Heading B7L. A basket cart conveyer system comprises a basket cart 4 having wheels 4.5, 4.6, 4.7 and 4.8, Figs. 1 and 2, each swivellable about a vertical axis, and engageable in guide rails 1.1, 1.2, 1.3 and 1.4, respectively, of a conveyer track 1, inclined sections of the rails being displaced relatively to each other so that the cart remains horizontal as it is moved up the inclined section of the track by carriers 5.2 on an endless chain 5 driven from an electric motor 8, gear 9, a chain 10 and sprocket 7, the motor 8 having a brake 11 releasable by an electric motor 12. In order to ensure that a basket cart 4 can only be driven up the conveyer track with its wheels all positioned to trail as shown in Fig. 1, a normally closed electric switch 13 fixed by a support 14 to the rail 1.4 and operable by a cam 15 on the cart 4 is positioned relative to normally open electric switches 16, 17, 18 and 19 in the rails 1.1, 1.2, 1.3 and 1.4, respectively, and operable respectively by the cart-wheels 4.5, 4.6, 4.7 and 4.8, so that all switches can only be operated simultaneously to cause operation of the motors 12 and 8 when the wheels are correctly positioned, at the entry region of the conveyer. Referring to the electric circuit of Fig. 4, the electric motors 8, 12 are connected to an alternating current source R, S, T through a three-pole main switch 21 and a three-pole contactor 22.1 operable by a control relay 22. The control circuit fed from the lines R and S includes a normally closed stop push-button 25, the normally closed contacts 13.1 of the switch 13 in parallel with the series connected normally open contacts 16.1, 17.1, 18.1 and 19.1 of the track switches 16 to 19, a start, normally open, push-button 24 and the relay 22. When the push-button 24 is operated the relay 22 is held by a contact 22.2. If the basket cart wheels are correctly positioned all the track contacts will be closed when the contacts 13.1 are opened and thus the control circuit remains energized, but if any wheel is incorrectly positioned, the control circuit is broken when the contacts 13.1 are broken and thus the motors 8 and 12 are deenergized.

Abstract: 358,375. Coking pitch. BARRETT CO., 40, Rector Street, New York, U.S.A.- (Assignees of Hamlin, M. L. ; Lynbrook, New York, U.S.A.) Dec. 22, 1930, No. 38508. Convention date, Dec. 28, 1929. [Class 55 (ii).] When coking pitch, the oven or retort is charged partly full of pitch in the first step, and, when this pitch is completely coked, an additional quantity less in amount than the first is added and coked. The pitch, when it is charged into the hot oven, froths up, and the amount added is such that this froth will not more than fill the oven space In an example, the oven is first half filled and when ebullition ceases, one-half of the amount first added is then charged, with the result that about three-quarters of the oven is filled. In a third step one-quarter of the amount added in the first step is charged, and so on until the oven is filled.

Abstract: 987,217. Ion sources; mass spectrometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 1, 1962 [Nov. 4, 1960], No. 38067/60. Heading H1D. A vacuum lock for isolating the ion source of a mass spectrometer from the rest of the instrument comprises means for moving successively as required, a plurality of expendable sealing elements into a vacuum sealing position and subsequently discarding each element after a sealing operation. In one embodiment, Fig. 3, when it is desired to seal off the ion source orifice 8, a phosphor bronze ball received from the magazine 6 is fed to the orifice 8 by a movable block 26. The ball is clamped in position by the pressure of member 5, air being forced into the annular chamber 17 between bellows members 15, 16 for this purpose. The ball is released by evacuating chamber 17 and forcing back member 5 by means of a fluidoperated lever mechanism. On retracting block 26 the ball 3 drops into the receptacle 22. In another embodiment, Fig. 9, diaphragm sealing elements are fed from a magazine to a slot 68 in a rotatable sector plate 62. A diaphragm in slot 68 is then moved over the ion source orifice and clamped into position by a similar mechanism to that of Fig. 1 (not shown). When the diaphragm is released and sector plate 62 retracted, the diaphragm carried in slot portion 70 drops through a hole in bridge member 78 into a receptacle. In both embodiments electrical provision is made for signalling an indication when the magazine is empty.

Filed: 1957-12-13
Abstract: 843,409. Transistors. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 13, 1957, No. 38777/57. Class 37. A high power transistor comprises a wafer having across its thickness dimension a collector zone, a base zone, the surface layer of which is of enhanced conductivity, and a plurality of parallel linear inclusions of opposite conductivity type to the base zone extending from the surface into the base zone through the surface layer to form emitter zones. The emitter zones are contacted by a series of projections formed on a common emitter electrode. In the embodiment one face of a wafer of 10 ohm. cm. P type silicon is exposed to the vapour of an acceptor impurity such as aluminium to produce a high conductivity P type layer. A film of inorganic insulating material such as silica is then produced over the the top surface by evaporation or by anodisation or other surface treatment. through a mask covering the edges of the surface. A series of parallel lines is scribed by a ruling engine through the insulating layer to expose the wafer surface. The wafer is then exposed to the vapour of a donor impurity such as phosphorus at 1000C., the edges of the upper surface being again masked. The impurity diffuses into the whole of the lower surface and the exposed parts of the upper surface to form an N type layer on the former and a series of parallel linear N type inclusions in the latter. The N type inclusions are then electrically connected to form a common emitter electrode by evaporating silver over the entire scribed surface of the insulating layer, a collector contact 42 made by evaporating silver over the surface of layer 12, and a base contact 44 soft soldered to the edges of the upper surface of the wafer. In an alternative embodiment the lower surface of the wafer is masked during the heating in donor vapour and the N type collector layer formed subsequently by fusing antimony or arsenic alloys to the surface. The high conductivity P type layer ensures that the current path between the emitter junctions and the physically remote base contact is of low resistance.

Title: Remote transmission of printed matter
IPC: H04N1/00
Filed: 1964-09-25
Abstract: 1,056,419. Television. E. V. SCHOLZ. Sept. 25, 1964 [Sept. 25, 1963], No. 39273/64. Heading H4F. Newspaper or other printed matter is scanned line-by-line in a normal television fashion and the resulting signals multiplexed with normal television programme signals in a manner such that at a receiver the matter is reproduced in the upper or lower margin comprising only 5% of the cathode-ray tube picture area. The scanned line on the printed matter occupies only a part of the height of a printed character and the signals due to each line are repeated, e.g. by signal repetition or by repeated scanning along one line, so that reproduction at the receiver in successive lines in the normal manner results in a vertical expansion and hence distortion of the matter. The system thus provides for the transmission and reproduction of the matter without serious restriction of a normal television programme, which may be effected simultaneously, and also results in the reproduced matter being distorted, so that it cannot be readily interpreted, in that only a part (distorted) of a line of characters is visible at any instant. Reproduction of the matter is effected by a photographic electrolytic or electrostatic recording apparatus which " views " only that part of the cathode-ray tube screen which reproduces the matter. Where the matter is reproduced in the upper margin the recording apparatus is provided in a housing which is clamped to the top of the receiver cabinet and either has a part which projects downwardly over the upper margin of the screen or is provided with a mirror (adjustable) to direct light from the margin into the housing. It is necessary to restore the vertical scale of the matter to offset the distortion which is introduced and this may be effected by one or more cylindrical lenses. Alternatively or additionally where electrolytic or electrostatic recording is employed, the restoration may be effected by photo-conductive means which are utilized to convert the light image into electrical signals. For example, the margin of the screen may be covered with a strip of photoconductive material of a width sufficient to respond to the whole height of the margin. The strip is provided with one common connection and a series of further connections arranged at elemental intervals along the strip so as to divide the image line correspondingly. The recording apparatus may be switched on and off from the transmitter by an ultrasonic signal sent over the television sound channel.
