Title: Improvements in or relating to apparatus for generating sawtooth currents
IPC: H03K4/28
Filed: 1956-05-04
Abstract: 805,143. Sawtooth current generating circuits. FERNSEHG.m.b.H. May 4, 1956 [May 5, 1955], No. 13823/56. Class 40 (6). In a circuit for generating a sawtooth current in a coil the coil is connected in parallel with a valve and in series with a load across the source of current and signals are applied to the grid of the valve to render it conductive during the flyback intervals. During the forward stroke, current flows through a resistor 2 into the deflection coils 7 of a cathode-ray tube and this current increases until a valve 1 is rendered conductive by a pulse applied to its grid, whereupon the current through the coil reverses and so produces the flyback. The forward stroke is linearized by a rectifier 9 connected in series with a biasing condenser 10 across the coil and by a saturable reactor 8. The amount of bias and thus the amplitude of the scan may be adjusted by means of a variable resistor 11. The components outside the dotted rectangle 20 may be located remotely from the deflection coils and coupled thereto by a cable 6. Ringing in the linearizing inductor 8 may be prevented by a resistor-capacitor combination located at 18, 19 or at 18<1>, 19<1> and a centring current for the deflection system may be introduced by a potentiometer system 13, 14, 15 and choke 17. The load resistor 2 may be replaced by a valve (Fig. 3, not shown) which may be rendered conductive during the forward stroke and non- conductive during the return stroke by applying pulses to the control grid and derived by a phase-reversing transformer from the pulses applied to the grid of valve 1. By adjusting the bias on the rectifier to a value somewhat less than that necessary to ensure linearity over the whole of the working stroke it may be arranged that changes in the resistance of the cable 6 have only a small effect on the linearity and amplitude of the deflection current.

Abstract: 680,609. Automatic altitude control. BENDIX AVIATION CORPORATION. June 13, 1951 [June 23, 1950], No. 14046/51. Class 38 (iv). A preselected altitude control arrangement has two aneroid altitude sensitive elements arranged to give respectively coarse and fine control signals to an automatic pilot to bring the craft to and maintain it at a preselected altitude. Provision is made when the craft is flown manually, for maintaining it at that altitude. Coarse control 1.-An aneroid 15 operates through lost-motion springs 27 and sector 21, a contact arm 13 movable between adjustable contacts 9, 11 which may be preset by knob 3 to a selected altitude as indicated on a drum dial 5. While aneroid-operated contact 13 engages contact 9 or 11 one of the relays 33, 35 is energized to apply a constant amplitude signal, from a centre-tapped transformer 43, in one phase sense or the other (180 degrees through a data smoothing network 47 as described in Specification 662,919 to the automatic pilot. As the craft approximates to the required altitude contact 13 floats between contacts 9, 11 and relays 33, 35 are de-energized. Fine control.-The altitude selector knob 3 also drives the rotor of a Selsyn transmitter 53 to energize a further Selsyn 61 having its rotor 63 controlled by an aneroid 65 to apply a signal over the normally-closed contacts of relays 33, 35 to the data smoothing network and automatic pilot, which brings the craft accurately to the required altitude and maintains it there. Maintaining a given altitude.-The altitude preselection arrangement is operative when the switch 147 is in the first position to energize relay 51 and connect the altitude signals to the data smoothing network. In the " off " position the output of the data smoothing network is shorted by relays 51, 145.
