Abstract: 730,294. Testing timepieces. WALKER ELECTRONICS, Ltd. June 18, 1953 [June 18, 1952], No. 15316/52. Class 139. A watch or like timer comprising an electronic oscillator 17, 18, Fig. 2, to be tuned to a standard beat and thereafter to the mechanism to be tested and means for visually indicating synchronism or the lack of it, is characterized by the oscillator having two independent means of frequency adjustment for synchronizing to the standard beat. and to the mechanism to be tested respectively, the adjustment of the latter means being exhibited upon a scale. A microphone which picks up the beat of a standard watch is connected at 9 to the input of an audio frequency voltage amplifier comprising a pentode 11 and a twin triode 12 which supplies through a switch 8 a loudspeaker 13 and through appropriate resistances and condensers and a rectifier 10 the grid 14 of a cathode ray tube 1. The power pack comprises a mains transformer 15 and a rectifier 16. The oscillator 17, 18 is tuned to a standard frequency preferably 30 c /s by adjusting the resistance 19. The output of the oscillator is connected through an amplifier and phase changer 23 to the plates 24, 25 of the cathode ray tube. If the beat of the standard watch is 5 ticks to the second a stationary bright spot will appear on the screen of the cathode ray tube. The standard watch is then replaced by a watch of the same train to be tested and the resistance 21 is adjusted by the knob 3; Fig. 1, until the bright spot is again stationary and the required adjustment is read from scale 2. A watch of 14,400 train making 4 ticks per second will produce a spot of light alternately at opposite ends of the time base circle. A resistance 22 is adjusted with the switch 7 opened to time the oscillator to 28.8 c /s which is used for watches of other trains.
