Abstract: 708,549. Television. MURPHY RADIO, Ltd. July 11, 1952 [July 11, 1951], No. 16440/51. Class 40 (3). [Also in Group XL(c)] In a television receiver, particularly of the single side-band type, in which interference is blotted out by a "spotter" circuit, interference due to negative overshoot of the interference pulses is also removed. As shown, the cathode self bias of the last radio or intermediate frequency amplifier valve 1 is made small so that grid current flows when the input exceeds the maximum signal amplitude, during interference, and charges negatively a grid circuit storage condenser 3 leakage of which occurs across a shunt resistor 4 following the interference pulse and produces a positive decreasing voltage in the anode circuit of valve 1 which is injected through a capacitor 14 into the load circuit 11, 12 of the detector diode 7. The arrangement is such that the positive voltage thus injected into the grid circuit of the video amplifier 13 compensates in amplitude the overshoot negative voltage following an interference pulse. The " spotter " diode 18 during interference applies a voltage developed across a section 15 of the video amplifier anode load 15, 16 through a capacitor 19 to the grid of the cathode modulated cathode ray tube to counteract the interference pulse to the cathode. Bias for the tube and spotter respectively is applied through leads 26, 23.

Title: Improvements in and relating to devices for filling bottles or other containers with fluids
IPC: B67C3/26
Filed: 1936-06-13
Abstract: 475,148. Filling-nozzles. WHITE, R. June 13, 1936, No. 16543. [Class 125 (ii)] Containers are filled with fluid to the required height by first filling above the height and then removing excess by a suction action. A filling-nozzle comprises a barrel a and valve c supplied with fluid by gravity or otherwise, connected by a flexible rubber tube f to a collar d which carries an adjustable filling jet e, an overflow tube h, and a rubber seating to receive the mouth of the container. The container is pressed against the collar d so that the tube b lifts the valve c off its seat and the container is filled to overflowing. The container is then withdrawn, which first shuts off the supply at valve c, and then causes the rubber tube f to exert a suction effect and remove excess liquid up the tube e via aperture g into the space i. The final level of liquid is adjusted by moving the jet e in or out. The suction action may also be obtained with a pump or piston action.

Title: Apparatus for maintaining a predetermined relative position of a  moving web of material and an element
IPC: B65H23/02
Filed: 1972-04-11
Abstract: 1377876 Transverse web registering KELVA AB 11 April 1972 [14 April 1971] 16572/72 Heading B8R A device for maintaining a predetermined relative position of a moving web 10 and an element comprises a fluid flow web edge sensor 11 fixed relative to the element, and an air pressure servomotor 12 for adjusting said relative positions, the sensor being connected to a source 18 of pressurized air via a control valve 16 which includes two diaphragms 30, 40 controlling air flow to the servomotor in dependence upon changes of air pressure supplied to a chamber 58 between the diaphragms via the sensor the changes being due to deviation from said predetermined position. In the predetermined position, the air flow from sensor orifice 25 directed past the web edge and through conduit 28 to the chamber 58 is sufficient to hold a seal 42, connected to diaphragm 40, down against valve seat 43 and insufficient to raise diaphragm 30 to open valve 33. If the web edge projects too far into the sensor, the air flow is restricted, allowing diaphragm 40 to be raised by a spring 54 thereby opening the valve seat 43 and connecting the servomotor 12 to atmosphere via passages 57, 49, 52. This allows a servomotor spring 12<SP>11</SP> to effect a relative movement between the web 10 and element, e.g. via guide rollers engaging the web or by movement of the element mounted on a carriage. Should the web edge project not far enough into the sensor, air flow is increased raising diaphragm 30 and opening valve 33 via pin 32 thereby connecting the servomotor to the pressurized air inlet 18 via passages 21, 37, 38. This pressure actuates the servomotor to effect relative movement in the opposite sense. The bias of spring 54 is adjustable.

Abstract: 1349811 Rolling mills; shearing ALCAN RESEARCH & DEVELOPMENT Ltd 11 April 1972 [27 April 1971] 16740/72 Headings B3M and B3W Apparatus for smoothing the edges of a number of metal strips slit longitudinally from a broader strip includes pairs of rolls 28, 29 (Fig. 3) which act on the edges of the strips 20a, 20b and 20c. An initially broad strip 20 (Fig. 1) passes through a slitter 22 which may trim the strip edges, and slit the strip into from 2 to 10 separate thin strips. The strips pass through guide rollers 84 and 85, further guide rollers 44 and 45, the edging rolls 28 and 29, guide rollers 86 and 87, and are coiled on a common spool 25. Each pair of guide rollers 44 and 45 is located upstream of a pair of associated edging rolls, the two pairs being mounted in common carriers 38 and 39. Each roller 45 has a radial fin 47 which extend into a groove in an associated roller 44 and locates an edge or edges of the strips. Each edging roll 28 or 29 (Fig. 7) is formed by two individual rolls 30 and 31 separated by a disclike nylon spacer 33. Each roll has a frustoconical rolling surface and is mounted for rotation on a common shaft 34. The upper carrier 38 (Fig. 6) is supported at one end by a transverse beam 77 and a pivot bar 79, and is spring-biased at its other end by a spring 40. The springs for all the upper carriers bear against a beam 42. The beam may either extend laterally between fixed side plates 66 (Fig. 1) or may be carried between a pair of pivotable arms. In the latter case, the upper carriers can readily be pivoted upwardly away from the strips. The lower carrier is supported by a pair of beams 68 and 69 and is adjustably clamped to the beam 69 by a bolt 74. Alternatively, a spacing collar may be located between the side plates of the carriers, the collar being clamped to the beam 68 to laterally locate the carriers. The pivot bar 79 may be dispensed with and a slidable latch used in co-operation with the beam 77 (Fig. 12 and 13, not shown). To align the upper and lower carriers relative to each other, the upper carrier of each pair may carry a vertical blade which passes downwardly between two strips to engage a recess in the lower carrier. When thin strips or foil are rolled, further guide rollers may be positioned between adjacent sets of edging rolls, the further rollers engaging the surface of the strips and being supported in carriers similar to those for the edging rolls.
