Title: Improvements relating to colour television
Inventor: HARKER MAURICE GEOFFREY
IPC: H04N9/24
Filed: 1957-01-31
Abstract: 880,474. Automatic control systems for colour television apparatuses. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 31, 1958 [Jan. 31, 1957], No. 3369/57. Class 38 (4). In an automatic scanning control system for a colour television apparatus, a screen of a cathode-ray tube 1 comprises a series of groups of parallel strips 2 of phosphor, which fluoresce respectively red, green and blue when excited by the beam of the tube moving transversely to the strips, and an indexing strip 3 of magnesium oxide is superimposed on one strip in each group. Signals representing the colour components of a scene are applied to a cathode 10 through gates 7-9 which are normally closed. The line deflection of the beam is effected by scanning coils 11 energized from a generator 12 having a waveform 13 and by deflecting plates 16 energized from an auxiliary generator 14 having a waveform 15 of frequency corresponding to the rate at which the strips are traversed by the beam. The superimposed fields due to coils 11 and plates 16 cause the beam deflection to be of a staircase form by which the beam dwells on a strip 2 and moves rapidly to the next strip. As the beam passes across an indexing strip 3 a voltage pulse is developed across a resistor 5 and through an amplifying and shaping circuit 17 applied as a rectangular pulse 18 to a delay line 19, comprising a flipflop chain, and to a comparison circuit 21. The total delay of the line 19 equals the time for the beam to scan from the mid-point of one indexing strip to the mid-point of the next indexing strip and signals are taken from the appropriate points in the delay line to open the gates 7-9 at the correct moment. An output signal is taken from the end of the delay line 19 and applied through an amplifying and shaping circuit 20 to an input of the comparison circuit 21. The output signal from the comparison circuit, representing in magnitude and sign the variation in relative timing between a delayed indexing signal and a succeeding indexing signal, is applied to the generators 12, 14 so as to linearize the scanning waveforms. The deflecting plates 11 may be replaced by auxiliary scanning coils. Specification 714,154 is referred to.

Patent GB-284675-A (GB)
Title: Automatic means for stabilizing bodies travelling under water
IPC: B63B21/66
Filed: 1928-02-03
Abstract: 284,675. Ginocchio, M. Feb. 3, 1927, [Convention date]. Sweeping mines.-A paravane or like body, a-b, Fig. 2, is provided (1) with a pendulum h, Fig. 4<A>, controlling an obturator i for a pipe s leading to a cylinder l in the stem of the paravane, and (2) with a vane f, Fig. 4<B>, at the stem, controlling an obturator g for a pipe m leading to a cylinder k near the middle of the paravane. Pistons t, n in the cylinders l, k are connected by links u, o to a double-armed lever p on the transverse horizontal shaft q of side rudders r, Fig. 2. If the paravane is deflected about its longitudinal axis, the pendulum, retaining its vertical position, causes the obturator i to uncover the pipe s. The dynamic pressure of the water is communicated through this pipe to the cylinder l, and the piston of that cylinder imparts a deflection to the rudders r. If the paravane is deflected in another plane, the vane f causes the obturator g to uncover the pipe m, and the piston n imparts an opposite deflection to the rudders r. The cylinder k is made of larger diameter than the cylinder l, so that in the event of both pipes s, m being uncovered, the piston n overcomes the efforts of the piston t and causes the deflection of the rudders r. The paravane shown comprises two floats a, b, Fig. 2, braced together by a lattice girder c and plane d.

Filed: 1916-03-11
Abstract: 104,719. Western Electric Co., and McBerty, F. R. March 11, 1916. Addition to 3360/14. Automatic exchange systems.-Relates to a modification of the means for controlling the movement of a power-driven switch by number impulses described in the parent Specification. The invention is described as applied to the control of a switch 13<1> by impulses produced by the key 11 and relay 12, and subsequently by reverting-impulses produced in the relay 12<1> by the movement of a brush 28 of a selector 26 over a toothed segment 29. The contact 14 of the switch 13<1> is earthed during the movement of the switch from one stopping position to the next. When the relay 12 is energized, a circuit is completed over the back contact of relay 17 for the clutch magnet 13, and as soon as the switch begins to move, the contact 14 closes a circuit for the relays 17, 18. The relay 17 locks up under the control of relay 12, and the relay 18 completes a new circuit for the clutch magnet 13, which is maintained until the switch 13<1> reaches its first stopping position, when the contact 14 opens the circuit of relay 18 and thus arrests the switch. When the impulse relay 12 is de-energized and the contact 14 is also opened, the relay 17 deenergizes and prepares a fresh starting-circuit for the clutch magnet 13, which is closed when the relay 12 is energized by the next impulse. The control of the switch 13<1> by the relay 12' is effected by the relays 17<1>, 18' in exactly the same manner as by the relays 17, 18. Specification 5653/13 is also referred to.
