Title: Improvements relating to cathode ray tube apparatus
Inventor: RASELL JOHN ALBERT
IPC: H04N3/18
Filed: 1949-07-01
Abstract: 706,005. Cathode ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 28. 1950 [July 1, 1949], No. 17401/49. Class 39(1) [Also in Group XL(b)] In cathode ray apparatus in which the beam is focused and deflected over a screen, and in which the E.H.T. voltage for the final anode is derived from a poor regulation power supply 7 so that the E.H.T. voltage varies with variations in the beam current, particularly due to the beam modulation in television receivers, and in which the E.H.T. power supply is fed with current from a relatively low voltage source 1, consequential variations in potential of the current fed to the E.H.T. power supply are fed from point 21 to a grid of an amplifier tube 11 to vary its gain and so to -set up compensating variations in its output current which is fed to deflecting and/or focusing means. As shown the output of tube 11 is connected to focusing coil 9, and, through transformer 18, to line scanning coils 17. The relatively low voltage is defined as a voltage suitable for supplying the anodes of amplifier valves in the apparatus and may be 200-400 volts while the E.H.T. voltage may be 4000-8000 volts. A further tube similar to 11 may be provided for energizing the frame scanning coils in a similar manner, Fig. 2 (not shown). A rectifier 1 feeds a D.C. voltage to converter 7 via smoothing condensers 4, 6 and resistor 5 the converter 7 preferably being a high frequency oscillator, the applied voltage controlling the amplitude of the oscillations, and having means for rectifying the oscillations, and the rectifier 1 is also connected via focusing coil 9 and smoothing inductance 10 to the anode of tube 11; the coil 9 has a shunt condenser 13 to reduce ripple and inductance 10 and condenser 14 also serve for smoothing purposes. A grid electrode of tube 11 is fed via decoupling circuit 15, 16, from the junction of resistance 5 and converter 7. Electron discharge tubes represented at 12 are for amplifying the incoming picture signals and for applying them to the modulating electrode of the cathode ray tube. Due to the internal resistance of rectifier 1, the variation in output voltage thereof due to variation in the current input to converter 7 is compensated to some extent by the variation of current through coil 9. Specification 623,037 is referred to.

Filed: 1959-05-28
Abstract: 879,164. Filters. TROOST-BLECHER, I., and ROMUNTER, W. May 28, 1959 [May 28, 1958], No. 18199/59. Class 46. Each plate of a supply-pressure filter press is provided with a short horizontal member 25, 25a ... in the plane of the plate, through which member passes a pin 28 on which is mounted a two-armed locking hook 35, 36, Fig. 3, which is cranked along its length. The arm 35, when the plates are in normal position for filtering, engages the projecting end of the pin 28a of one of the neighbouring plates (the right-hand one, as seen in Fig. 3), the plates being thereby retained when the clamping means (not shown), is released. The plates may be separated one at a time from the assembly and moved to the left by a series of equally-spaced pawls 26 pivoted on a leftward moving endless chain 23. Any pawl which for the time being is above the assembly of plates rides along, and is maintained horizontal, by its lower surface 33 sliding along the tops of the members 25, 25a. . . this being the position of the pawl shown in Fig. 2. When the surface 33 of a pawl has passed beyond the member 25 of the left-most plate of the assembly the pawl swings clockwise by an amount governed by a pin-and-slot connection 31, 32, whereupon a pin 34 on the pawl (see also Fig. 2), comes in contact with the arm 36 of the locking hook of the left-most plate and tilts the hook to the position shown in Fig. 3, in which position the arm 35 is freed from the pin 28a of the neighbouring plate to the right. Shortly afterwards the hook head 37 of the pawl (which has fallen between members 25a and 25) makes contact with member 25 and tows the plate to which it is attached to the left. On reaching the clamping head or fixed abutment at the end of the press a control surface on the press frame raises the pawl to free the plate (when this is the first plate to reach the end of the " displacement path "); subsequent plates are freed from their pawls at the end of the displacement path by contact of surface 33 with member 25 of the previous plate.
