Title: Colour picture tube
IPC: H01J29/32
Filed: 1974-06-13
Abstract: 1442915 Colour television tubes MATSUSHITA ELECTRONICS CORP 13 June 1974 [18 June 1973] 26290/74 Heading H1D A colour television tube with shadow mask 8 adjacent to luminescent screen 9 on faceplate 11 carrying triads of green, red and blue phosphor strips 12, 13, 14 energized by respective simultaneously scanned beams of electrons from guns 2, 3, 4 has vertically elongated slots in mask 8 arranged in quincunx with diagonals parallel to the screen diagonals, and with the triads of vertical strips of phosphor separated within and outside the triads by dark film filling all gaps, these measures serving to reduce stripe and moirÚ effects. The mask 8 is slightly dished away from the guns so that if numbers of slots and triads match, as is preferred, the horizontal and vertical pitches of the triads will be slightly greater than corresponding slot pitches. The phosphor strips are made slightly smaller than the electron-illuminated areas of the screen, filling gaps left in the dark coating. Optimum contrast and brightness combination is obtained when the vertical gap between adjacent strip ends is 5-20% of the vertical strip pitch. The numbers of slots in horizontal and vertical scans should be at least 300 and 100 respectively. The ratio of vertical slot and strip pitch to the corresponding scanning line spacing should be near 8/(2n-1), n being an integer, to further reduce moirÚ effects.

Title: Grounded aircraft trainers
IPC: G09B9/20
Filed: 1959-07-31
Abstract: 922,413. Grounded aircraft trainers. ACF INDUSTRIES Inc. July 31, 1959 [Aug. 11, 1958], No. 26317/59. Class 4. A grounded aircraft trainer feel force simulta- or comprises means for generating a signal representing control surface position, and means responsive to the signal and to potentials representing normal control surface deflection limits, and having an output representing a feel force due to an attempt to deflect the control surface beyond its normal limits. The apparatus is intended to simulate the feel produced in a system in which an elevator, for example, is operated by a tab through a torque tube device, such that when the elevator reaches a deflection limit in either direction, (which limit corresponds to a control column deflection which is a function of the parameters of flight), further deflection of the control column winds up the torque tube device to give an increase in feel force. In the Figure a constantly A.C. energized potentiometer 2 is driven by a Mach number servo, and provides the input to an amplifier 6, the feed back circuit of which comprises a potentiometer 8 driven by an altitude servo. Amplifier 6 energizes a potentiometer 10, the wiper of which is driven by a trainee's dummy control column. The resulting signal representing control surface deflection is fed through a buffer amplifier 18 to the junction of a diode pair 26, 28 of a diode circuit 20. Diode pairs 30, 32 and 34, 36 of the circuit have their junctions connected to potential dividers energized over terminals 42, 44 by oppositely phased reference voltages, corresponding to the limits of control surface deflection. In general, the upper and lower limits will be different, and a further balancing signal is added at terminal 54, so that in the absence of a signal from amplifier 18 there is no resultant potential at the input terminal 90 of amplifier 24. The circuit is such that amplifier 24 has zero output while the signal from amplifier 18 lies between the potentials representing control surface deflection limits, but the output rises as the signal exceeds either limit. The output signal is multiplied by functions of control column deflection and airspeed by potentiometers 12 and 14 driven by the control column and airspeed servo respectively, and the resultant signal is added to the conventional feel force simulating signal, which operates a torque device (not shown) acting on the control column. A further diode circuit in parallel with the feed back resistor 64 of amplifier 24, has positive and negative reference phase voltages applied to terminals 82 and 84, the circuit being such that the output of amplifier 24 is limited to lie between the potentials applied at terminals 82 and 84.

Filed: 1919-11-04
Abstract: 158,362. Matthews, R. Nov. 4, 1919. Regulating delivery by varying effective area of piston.-A pump for delivering regulable quantities of liquid comprises a chamber 1 provided with inlet and outlet valves 2, 3 and a plunger 4 adapted to be reciprocated by external means. A second compensating plunger 12 of approximately the same diameter as the plunger 4 is slidably mounted in an adjustable block 7 in line with the first plunger so that, when the plunger 4 strikes the plunger 12, the two travel together and delivery ceases. The plunger 12 carries a valve 13 which connects the chamber 1 with the inlet pipe 11 through ports 7a, 6a, 10, and 9 when the valve is raised by the inward movement of the plunger 12. An extension 15 of the plunger 12 works in a chamber 17 connected to the inlet pipe. The delivery is varied by adjusting the block 7 by means of rods 7<1>, 7<11> operated by hand or governor. Several such pumps having plungers of different diameters may be combined.
