Abstract: 1,116,750. Recording-apparatus. T.H. GIFFT. July 15,1966 [July 15,1965], No. 32015/66. Heading G1J. [Also in Division G3] In a scanning recorder of the type in which paper 14 drawn between a conducting blade 16 and stylii 11 on a movable band 12 is marked by electrochemical action, the speed of an electric motor 18 driving the band is controlled by a system in which pulses corresponding to band speed are compared in frequency and phase with pulses derived from an oscillator 30. Band speed pulses are generated by a photo-electric arrangement Fig. 6 (not shown) in conjunction with closely spaced holes in the band; additional holes, one for each stylus, produce phasing signals in a second detector, which are used in the signal and keying control circuits, Fig. 2 (not shown). The paper drive is by a stepping motor energized by the band speed pulses via a frequency divider which is reset by each phase pulse, and a shift register and selector switch arrangement (60) enables the operation to be programmed. Scale lines can be added by generated signals applied to the stylii; they can be interrupted at timed intervals by a synchronous motor driven cam (80). Frequency dividers in both pulse circuits provide for range changing. Each stylus 11 comprises flat spring steel with a wide writing edge which makes point contact (through the paper) with the blade 16, which is canted to distribute wear along the stylus and for the same reason is oscillated transversely to the paper about once in forty minutes by a motor driven cam 122, Fig. 7 (not shown).

Filed: 1923-12-22
Abstract: 230,934. Austin, G., Macfarlane, J. C., and Macfarlane, W. A. Dec. 22, 1923. Motors, controlling.-Relates to apparatus for governing the speed of electric motors by displacing the brushes relatively to the field poles. A centrifugal governor B acts through an adjustable linkage C, D and a swinging tappet E<2> upon one arm of a short lever F attached to a sleeve H coupled to a brush-shifting frame A<1>. The sleeve H surrounds a shaft G<6> which is operated through gearing by a handle G<1> simultaneously with the actuation of a switch (not shown) for turning on current to the motor. The shaft and the sleeve are resiliently connected by springs G' in compression between projecting arms G<7>, H<1>, and the initial movement imparted to the shaft G<6> thus displaces the brushes from the neutral line in the direction corresponding with the required direction of rotation. The extent of which the brushes are shifted determines the torque of the motor. Simultaneously through a similar resilient connection between two arms K, J, the tappet E<2> is swung to its limiting position facing one arm of the lever F and ready to be rocked back by the action of the governor. In a modification, the connecting linkage between the governor and the brush-shifting gear is arranged to prevent manual movement beyond the neutral position until the speed is below a given limit.

Piston (23) is raised by fluid pressure during the approach stroke. The pistons 12 (and 23) are secured to diaphragms 14 (and 27), the former holding piston extension 13 in light sliding contact with the strip, during the return stroke. Diaphragm 14 may be omitted. The clamping pressure, applied by piston 12, is preferably not sufficient to feed the strip against an abnormal resistance.
