Title: Method of forming fluorescent screens of color picture tubes
IPC: H01J9/227
Filed: 1979-08-08
Abstract: A fluorescent screen for a colour picture tube is prepared by image-wise exposing e.g. through a colour selection electrode a photosensitive layer which becomes tacky and also cross- links, to become water insoluble, in the exposed areas.

Patent GB-798485-A (GB)
Abstract: 798,485. Gyroscopic apparatus. SPERRY RAND CORPORATION. Oct. 11, 1955 [Oct. 21, 1954], No. 28917/55. Class 97(3) [Also in Group XXXV] In an aircraft gyroscope, torque is applied in dependence on deviation in the angular relationship between the gyro and a directional reference so that the gyro is automatically maintained in a direction determined by the directional reference, and a turn-responsive device mounted on the aircraft and operating an electric switch, modifies the automatic control system for the gyro through a delay device so that such modification does not take place in consequence of yaw oscillations during otherwise straight flight. As shown in Fig. 3 a gyro vertically mounted in an aircraft comprises an electrically driven rotor 12 spinning about a vertical axis in a case 11 free to move about a horizontal axis 16 on a gimbal ring 10; pivoted about a horizontal axis 15 corresponding to the fore and aft axis of the aircraft. Normally, gyro errors are detected by gravity-responsive liquid level type pick-offs 18 and 49 respectively controlling torque motors 17 and 50 which erect the gyro by precession. When rate of turn of the aircraft exceeds a predetermined value, however, control of torque motor 17 is transferred from roll detector 18 to a second pitch detector 60. This is effected as shown in Fig. 4 by a switch 94, operated by a rate-of-turn gyro (not shown), to initiate the closing of one or other of two thermally-operated delay switches 108, 110, according to the sense of turn, so that a relay 25 or 29 is energized to effect the changeover with connections appropriate to the sense of turn. The delay provided by switches 108, 110 is sufficient to eliminate response to yaw oscillations during straight flight. Alternative operation with switches having delayed release is referred to. As shown in Fig. 1 the rate of turn gyro has a restraining spring 75 associated with a movable arm 76 which also operates switch 94. The amount of fluid damping is adjustable by a screw 87 adjusting the volume of a cylinder 85. The temperature of the fluid is controlled by a thermostat controlling an electric heater 92 surrounding the gyro.

Title: Control of a source of desired sound
IPC: H03G3/32
Filed: 1980-02-07
Abstract: To ensure that a signal such as a warning signal (e.g. an ambulance) 10 can be heard in a sound distribution area despite the presence of desired sound, (e.g. a car radio) 2, the system operates by measuring an external parameter (e.g., the warning signal) and attenuating at 7 the volume of the source of desired sound in accordance with the external measured parameter. The system may be arranged to respond to a succession of different frequencies characteristic of the warning signal, by means of filters 12 and time delay circuits 16. <IMAGE>

On lifting by the tractor linkage the beam is first tilted forwardly and upwardly causing the mole boring device (34) to move to the surface. On continued lifting, the chain tightens and the mole drainer is lifted bodily from the ground. <IMAGE>
