Title: Improvements in or relating to Colour Television Receivers
IPC: H04N9/47
Filed: 1967-05-11
Abstract: 1,186,907. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 11 May, 1967 [13 May, 1966], No. 21911/67, Heading H4F. A half-line frequency oscillator 1 is synchronized by line frequency pulses 6 and has its phase determined by colour synchronizing carrier signals 7, which change in phase in alternate lines, by means of a phase discriminator 14 which compares the phase of the oscillator output 2 with the phase of a signal 13 obtained from the discriminator 9 in the control loop, by which signals 7 synchronize the datum carrier oscillator 10, and controls a gate 5 whereby, in the event of incorrect phase, pulses 6 are isolated from the oscillator until such time as it runs freely to the correct phase. During this time the discriminator also operates a " colour killer " gate 15. When a signal is received which does not include colour synchronizing signals 7, discriminator 14 produces zero control output which maintains the synchronizing connection through gate 5 but disables the colour circuit through gate 15. In a first modification, the output of discriminator 14 is arranged to stop the oscillator momentarily in the event of incorrect phase. In a second modification, the discriminator output is used to detune the oscillator until the phase becomes correct. A detailed circuit based on Fig. 1 is described with reference to Fig. 2 (not shown).

Title: Improvements relating to shaft thrust balancing devices
Inventor: RUBBRA ARTHUR ALEXANDER
IPC: G01L3/14
Filed: 1950-09-06
Abstract: 707,737. Bearings. ROLLS-ROYCE, Ltd. Aug. 17, 1951 [Sept. 6, 1950], No. 22015/50. Class 12(1) A shaft thrust balancing device suitable for gearing having a number of layshafts, comprises a layshaft 10 provided with a helical gear 11, which shaft is permitted limited axial movement 23 on a quill shaft 17. A spring 25 biases the shaft 10 in the same direction as the normal axial thrust shown by arrow 22, and the layshaft is provided with an abutment 29 which co-operates with shoulder 30 on the shaft 17 to limit axial thrust in the opposite direction. The forward end of shaft 10 is closed by a plug 35 offering an axially facing surface 36 to a similar surface 40 on a piston element 37 sliding within the part 15 of the stationary structure, and the piston has a boss portion 37A slidably mounted on a spigot 38 retained in 15 by a split ring 39A and a circlip 39B which permit limited universal movement of the spigot. A duct 41 supplies pressure liquid to the forward side 37B of piston 37, and the liquid is then conveyed through port 42, passage 43, and restriction 44 to chamber 35A to lubricate the faces 36, 40, and then drain away through the bearing 13. The piston, which is prevented by a peg 45 from rotating, carries a chamfered ring 46, and is provided with a number of radial ports 47 which communicate with an annular recess 48. A lip 37C, upon movement of the piston, co-operates with a number of recesses 49 in the spigot to provide variable area ports through which fluid may pass from 41 through the passages 47 to the bearing 13. The area of the ports controls the pressure applied to the piston face 37B, which pressure produces an axial load on the piston which is transmitted across 36 and 40 to balance the thrust on shaft 10. The movement of the shaft 10 in the direction of arrow 22 tends to close off the ports and increase the pressure on piston 37, whilst movement in the opposite direction increases the port area and reduces the pressure. In a modification the spigot 38, and boss portion 37A of the piston are omitted, and the hydraulic control porting is afforded by the piston ring 46 in co-operation with passages angled through the cylinder wall 15B. A typical arrangement of grooving the surfaces 36 and 40 to permit controlled leakage and adequate lubrication, is also shown and described. In a gearing arrangement having a number of layshafts each layshaft may have a thrust-balancing device fed in parallel with pressure liquid from a common source, only one of such devices however being equipped with control ports. The hydraulic pressure may be measured to indicate the torque transmitted. The bearing 19 is designed to take the total thrust in the event of a breakdown to the hydraulic system.
