Title: High voltage generator
IPC: H04N3/19
Filed: 1973-06-04
Abstract: 1439272 EHT generators for TV receivers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 June 1973 [22 June 1972 (3)] 26558/73 Heading H2F In a high voltage generator particularly for the anode supply of a cathode-ray tube in television apparatus, two high voltage rectifiers are employed, one, 41 between the high voltage end of the EHT winding of the line deflection flyback transformer and the other 42 connected between the low voltage end of the winding and a point of lower potential. A tapping 37 on the winding is included, preferably for the provision of a D.C. focus supply and may be at a neutral point where no pulse voltages are present. The invention reduces the effective capacitance of the secondary side so as to allow tuning to fifth harmonic. A capacitor 6 may be selected to change the tuning and hence the pulse width on the secondary. In Fig. 5 (not shown) a parallel arrangement of a resistor and capacitor are connected between the rectifier 42 and ground so as to compensate for the effect of beam current on the focus potential. The output impedance may be reduced by tuning the lower portion of the secondary to the third harmonic and the upper portion to the fifth harmonic. The transformer may be immersed in a silicone oilfilled tank.

Title: Heat treatment of metal strip
Inventor: CUBBON ROBERT CLIFFORD
IPC: C21D9/58
Filed: 1962-07-11
Abstract: In a method and apparatus for the continuous heat-treatment of metal strip, the latter is raised to the treatment temperature by passage through a liquid heat transfer medium, e.g. lead-bismuth alloy, maintained at that temperature in a non-oxidizing atmosphere and quenched in a liquid heat transfer medium.  A single liquid medium may be used, being circulated from the quenching to the heating zones in counter flow to the strip and being <PICT:1003259/C6-C7/1> heated during its passage from the former to the latter zone.  The strip may be maintained at the treatment temperature by radiation or by direct resistance heating.  As shown in Fig. 1, strip 11 passes through limbs 14, 16 of a U - shaped vessel containing the heating medium, where it is heated to the desired temperature, and then through chamber 17 where it is maintained at temperature by radiant heaters 18 or by passage of current introduced through rollers 19, 21 &c. The strip then passes through limbs 20, 22 of a second U-shaped vessel forming the quenching zone, and leaves by way of heaters 24 and pinch rolls 25.  The liquid medium is circulated as shown by pump 42, a heater 60 being interposed between limbs 16 and 20. Specification 980,353 is referred to.

Title: Improvements relating to devices for transmitting electrically indications and movements to a distance
Filed: 1929-09-02
Abstract: 341,056. Liquid - level indicators. BARSTIES, W., 4, Luneburgerstrasse, Berlin. Sept. 2, 1929, No. 26658. [Class 123 (i).] In means for indicating electrically movements at a distance in which the movements of a transmitter over a branch of a wheatstone. bridge produce currents adapted to actuate a member movable over a second branch so that the balance of the bridge is restored, the transmitter and the member co-operate through the medium of an instrument the rotary coil of which lies in a third branch and is coupled mechanically to the member. In applying the invention to indicating the level of liquid in a tank means are provided for eliminating error due to tilting of .the tank. In the construction shown in Fig. 8, a tank 28 is provided with pressure caps 30, 32 connected to pipes 10 which are adapted, when the caps yield, to bridge a number of resistance windings depending upon the extent to which the caps are depressed. The resistances 2 are in the same circuit so that the total resistance is independent of the extent to which the tank is tilted. More than two pressure caps may be employed. In a modification the two pressure caps are connected by a pipe filled with liquid and leading to a third pressure cap which co-operates with a resistance, and are also connected by rods to diaphragms in a wall of the tank so as to compensate for pressure or vacuum in the tank. In the construction shown in Fig. 10, floats 45, 45<1> are connected respectively to arms 10, 10<1> pivoted on a shaft 44, the arms engaging a resistance 2. The resistance bridged by the arms is independent of the inclination of the tank and varies only with the variation of liquid in the tank.

Title: Improvements in and relating to electric amplifying circuits
IPC: H03F3/02
Filed: 1931-09-25
Abstract: 389,855. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Bedford, B. D. ; 329, Germania Avenue, Schenectady, New York, U.S.A.) Sept. 25, 1931, No. 26782. Convention date, Sept. 26, 1930. [Class 40 (v).] An amplifying-system comprises' a pair of vapour electric discharge valves 18, 19 of the grid-triggered type, connected across a direct-current supply 12, to the grids of which a 60-cycle signal input is applied in push-pull from a line 10, together with a 1000-cycle frequency from a valve 29 arranged to provide oscillations of triangular wave-form. The highfrequency oscillations stimulate the valves 18, 19 in alternate half-cycles, whilst the induced voltage across a reactance 13 in the high-tension supply co-operates with a condenser 20 to reduce the plate-potential of each valve in succession below the critical threshold value. The combined voltage applied to each grid is shown in curve 1 of Fig. 2, the parts above the line a representing positive voltages applied to valve 18, whilst the parts below the line represent positive voltages applied to the valve 19. Curve II is an oscillogram of the output from one of the valves, the effect of the applied signal being to increase the timeperiod during which each valve is conductive from a minimum to a maximum in rhythm with the signal voltage, as shown. Curve III represents the amplified signal output after the high-frequency component has been removed, by the filter circuit 32 .. 36, assisted by a resistance 15 in the supply line. The arrangement is designed to give a large poweroutput.

Title: Inking ribbon transport mechanism
IPC: B65H23/032
Filed: 1972-06-09
Abstract: 1364741 Feeding webs INTERNATIONAL BUSINESS MACHINES CORP 9 June 1972 [23 June 1971] 26927/72 Addition to 1309583 Heading B8R [Also in Division B6] A page-width ink ribbon 16 is fed in either direction between two take-up rolls (2, 4, Fig. 1) which are driven alternately by an inkribbon actuated reversal mechanism comprising a two-armed lever (46, Fig. 2) operating a switch (50). The rolls (2, 4) are rotatably and pivotally mounted on a fixed plate (6) and are rotatably and pivotally mounted in a pivoted plate (8). When plate (8) is pivoted about axis (10), the rolls (2, 4) are skewed with respect to each other so that transverse registration of the ink-ribbon can be achieved, as described in Specification 1,309,583 (see Division B6). When one or other of the drive motors (110, 112, Fig. 9) for rolls (2, 4) is energized with half-full voltage, it acts to tension the ribbon being wound on the other roll by the other motor energized with a fullvoltage. Transverse detecting.-The skewing operation of the rolls (2, 4) is controlled by a sensing finger 20, Fig. 4, and an arm 38 periodically moved to intersect the path of the ribbon 16 to sense the presence or absence of the ribbon, in a similar manner to that described in Specification 1,309,583. If the ribbon is under the arm, the movement of the ribbon causes the finger 20 to pivot which in turn allows the arm to drop. This sets either drive pawl 94 or 90 to engage one or other of the eeth 56 or 58 of a continuously rotating ratchet 54. This rotates a cam 32 through 180 degrees which moves a cam follower 34 attached to pivoted plate (8) so that the skew of the rolls is reversed. There are two pawls 90 and 94 so that one drives when one roll is winding and the other drives when the other roll is winding. When the ribbon has shifted from under the finger 20, the sensing arm again sets a drive pawl 90 or 94 and rotates the plate (8) back to the starting position by turning the cam 32 through 180 degrees. A cam 60 with diametrically opposed lobes 62, 64 raises the finger 20 via the sensing arm 38 to periodically move the finger 20 out of the path of the ribbon.
