Title: E.H.T. Supply particularly for Television Receivers.
Inventor: MARTIN KENNETH EDWARD
IPC: H02M7/06
Filed: 1968-09-16
Abstract: 1,170,198. E.H.T. power supply for T.V. tubes. MULLARD Ltd. 16 Sept., 1968, No. 43942/68. Heading H2F. E.H.T. (e.g. 25 kv.) is supplied to a T.V. colour receiver tube from a substantially conventional series multiplier circuit D 1  to D 5 , C 1  to C 5  (Fig. 3) fed at terminal A with flyback voltage pulses from the receiver line output transformer and a resistor R 1  and diode D 6  being provided across the input to clip ringing pulses and improve voltage regulation. When a flyback pulse occurs, the diodes D 1 , D 3 , D 5  conduct for a period t 1  (see pulse waveform, Fig. 2) to charge C 1 , C 3 , C 5 , respectively, while during the scanning period starting from instant t 2 , C 2  is charged via D 2  from the charge in C 1  and C 4  is charged via D 4  from the charge in C 3 . C 5  is the picture tube capacitance and during flyback a voltage pulse is applied via D 5  to C 5 , charging it to the E.H.T. potential of 25 kv., i.e. three times the peak input voltage, the input pulse voltage being additive to the voltages across C 2  and C 4 . Negative-going portions (shown hatched, Fig. 2) of ringing oscillations occurring at the end of a flyback pulse are clipped off as diode D 6  conducts current through the resistor R 1 , thus improving the voltage regulation. From the junction of D 6  and a capacitor C 6  a positive voltage, e.g. 800V is obtainable for supplying the A 1  anode of a shadow mask tube, which supply is smoothed by R 2 , C 7 . Focus potential (e.g. 5 kv.) is obtained from a variable resistor VR, which also helps to flatten the top of the flyback pulse, further improving E.H.T. regulation.

Abstract: 910,956. Adjusting roller nips. COURTAULDS Ltd. Dec. 28, 1960 [Dec. 29, 1959], No. 44066/59. Class 120 (2). In a pair of rollers 10, 10a for conveying a fibre bundle, one of the rollers 10a is mounted to be moved towards and away from the other roller along an arcuate path so as to vary the nip between the rollers a gear-wheel 25 being fixed to the shaft 19a of the movable roller 10a and the gear-wheel meshing with an internal annular gear 24a concentric with the arcuate path. A cantilever mounting for two such rollers 10, 10a is described for use in a top to tow apparatus (see Fig. 1, not shown) and comprises a frame 33 mounted on a carriage 13 which runs on rails 14 (see Fig. 1), the position of the carriage being adjusted by rotation of a handle operated gear 16 co-operating with a rack 17 on the carriage. The shaft of the lower roller 10 is mounted in bearings fixed relative to the frame 33 while the upper roller 10a is eccentrically mounted in a cylindrical housing 20 which in turn is mounted for rotation in the frame 33. The lower roller is driven by a chain engaging sprocket 22 while drive is transmitted to the top roller by a gear 23 which is keyed to shaft 19 at 23a and engages a gear 24 integral with an internally toothed gear 24a which co-operates with a spur gear 25 mounted on the shaft of the upper roller 10a. Alternatively the upper roller may be driven by friction through the tow, in which case a lever 27 is used to shift gear 23 out of engagement with gear 24. The separation of the rollers may be varied by rotating the housing 20 which has for this purpose an annular worm-wheel 32 meshing with a worm 31, the worm 31 being rotated, via gears 29, 30, by a handle 28. So that gear 25 remains in mesh with gear 24a during this rotation, it is arranged that gear 24a and the housing 20 are coaxial. Brushes 11 are arranged to clear the rollers. Specifications 899,143 and 910,955 are referred to.
