Title: Improvements in and relating to apparatus for monitoring a sequence of operations
Inventor: LAWSON WILLIAM MILLAR
IPC: G07C1/20
Filed: 1962-02-21
Abstract: 928,555. Time-checking apparatus. P. & O. RESEARCH & DEVELOPMENT CO. Ltd. Feb. 21, 1962, No. 6820/62. Class 106 (4). An apparatus for monitoring a sequence of differing output signals, includes a receiving device adapted to respond to the differing signals only when they conform to the predetermined sequence and when each signal occurs within a given time of the next preceding signal, and timing means adapted to operate an alarm device at a given time after being set, the receiving device being connected to the timing means and being adapted to reset it each time the receiving device responds to an input signal. To monitor the progress of a watchman on his round, a receiving device is supplied periodically with combinations of signals on input terminals a . . . f initiated by the watchman inserting a shorting plug into five-pin sockets located on his round. Each socket has a connection via the terminal f to the positive terminal of the supply, and is characterized by further connections to one or more of the terminals a . . . e, preferably conforming to a binary sequence. Thus, relays 6a . . . 6e are energized selectively at each stage of the watchman's round to represent in binary code the number of that stage. The contacts of a uniselector A are connected in circuits controlled by the relays 6a . . . 6e and their contacts 7a . . . 7e so that the uniselector is stepped on only when the correct binary pattern of control signals is received and leads to energization of a relay X. A second uniselector B is stepped on by half-minute timing pulses applied to a relay Z, and is " homed " each time relay X is energized. If this does not occur before the uniselector brush reaches contact 10-which has been set on a dial 8 as the maximum permissible time delay-a relay Y is energized, completing an alarm circuit and interrupting the supply of timing pulses. An indicator (not described) cooperating with banks 2 and 3 of uniselector A shows the location from which the last valid signal was received. Push-buttons P1, P2, P3 are provided for testing and restoring the circuit. Switches S1 . . . S4 provide for modifying the number of checking points on the watchman's round.

Title: Improvements in or relating to automatic rudder controls for sea-craft and air-craft
IPC: G05D1/02
Filed: 1929-03-02
Abstract: 318,538. Minorsky, N. Sept. 5, 1928, [Convention date]. Steering and balancing.-Ships and aircraft are steered automatically by an instrument dependent upon earths magnetic field and the field of a magnet on the vessel. The induced E.M.F. is magnified by a thermionic system and controls the rudder motor. A spindle 1, Fig. 1, is mounted in a frame 2 which is supported in gimbals in a ring 5 the outer edge of which is a rack engaged by an adjusting pinion 8 in a fixed ring 6. The spindle 1 carries a drum 10 having two symmetrical coils 11 which pass to discs 18, 19. These coils are influenced by terrestrial magnetism. A lower drum 12 on the spindle 1 has coils 13, 14 set at an angle of a/2 with respect to the direction of the coils 11 and connected to discs 20, 21, 22. These coils are under the influence of a magnet 15 carried by the frame 2. When the ship is heading correctly the induced E.M.F. of the coils balance. Brushes bearing on the rings lead an alternating current to a thermionic amplifying and rectifying system and on deviation of the ship unbalanced forces exist in the plate current of lamps 45, 46, Fig. 4, and are used through a differential milliammeter to indicate at 71 the deviation of the ship and pass to two oppositely wound excitation windings 47, 48 in a direct current generator 49 driven by a motor 120. The dynamo 49 actuates the rudder motor 52 or control valve or gear of the rudder engine. The dynamo 49 also has windings 50, 51 and a resistance 55 connected to them co-operates with a contact 54 which is movable by the rudder whereby as the rudder moves over the excitation of the dynamo is decreased and the rudder is slowed up or damped as its deflection increases. To include a control dependent on the angular speed of yaw, there is interposed in series with the plate circuits of the lamps 45, 46 the primaries of two transformers 57, 58, Fig. 5, which are suitably connected to lamps 64, 65 the plates of which are connected to the excitation windings 47, 48 and algebraically add a control to that exercised by the lamps 45, 46. If a further transformer set is placed in series with the lamps 64, 65, a control responsive to angular acceleration of yaw can be added to the winding 47, 48 The sensitiveness of the control may be modified by proving the resistances 37, 38 with movable contacts 68, 69. Alternatively the resistance 70 in the retum circuit of the windings 47. 48 may be variable or a variable resistance 126 in the field 125 of the motor 120 may be employed. For changing over from motor 52 to hand control 98, or vice versa, Fig. 7, a double bevel 93 is slidden on the drive shaft 90 so as to mesh with pinion 97 or pinion 100 accordingly.

Abstract: 667,268. Cathode-ray tubes. COMPAGNIE GENERAL DE TELEGRAPHIE SANS FIL. March 12, 1948 [March 13, 1947], No. 7653/48. Class 39 (i). In an electron microscope or like electron or ion beam tube having a gun, an object holder and a lens, an adjustable field is provided following the lens field to compensate for field distortion produced, e.g., by irregular lens adjustment or construction or external fields. Eight or six spherical or flat plates A, A1, Fig. 2, are circularly arranged near the first lens of a microscope and are connected respectively by sliding contacts 9<SP>1</SP> to potentiometer wires 10. The sliders are attached to a bar 9 movable over a scale. Continuous current is supplied to electrodes P1, P2 in a tank 2 containing a liquid and the potential across the plates can be varied by potentiometers 4, 5. The ends a, a1 of the potentiometer wires are connected to corresponding electrodes which are circularly arranged in the liquid and supported from a rotatable insulating disc 7. Similarly, the other ends l of the wires are connected in pairs to electrodes also rotatably mounted on a disc 8 within the liquid. The arrangement includes five points where potential adjustment is possible to correct for decentring and eccentricity, the adjustments being made by reference to the fluorescent spot. When the correcting potentials have been ascertained, the arrangement can be replaced by a single potentiometer. In another form, correcting fields are produced by electromagnets 12<SP>1</SP>, Fig. 5, and soft iron bars 11 which project through a magnetic screen 13. The continuous current in the coils can be adjusted by connecting the opposite connections A between adjacent coils to contacts of a potentiometer. Further adjustment may be secured by controlling the currents in three independent windings on each coil 12 by separate potentiometers. The soft-iron bars may be dispensed with. To correct for astigmatism only, plate electrodes 181, 18<SP>11</SP>, Fig. 8, which have rectangular or elliptical slots 19, ox two electromagnets, may be rotatably adjusted with respect to each other. Alternatively, two pairs of electrodes 201, 20<SP>11</SP>, Fig. 9, connected together, may be rotatably arranged. Further windings on the magnets 121, Fig. 5, may carry current derived from a phase shifter to correct for distortion caused by the supply mains. Voltages and dimensions are specified. The invention may be applied to telescopes.
