Abstract: 1293701 Line digitizers GERBER SCIENTIFIC INSTRUMENT CO 27 April 1971 [29 April 1970] 11582/71 Heading G4H In a line digitizer, in which a sensor 24 (Fig. 6) is automatically driven along line 22 by X and Y motors 68 normally controlled by a line following control 34, the position of the sensor, represented by the outputs of X and Y encoders 35, 36 being periodically stored in a temporary store 84 which when full transfers its oldest stored value to output means, when a sensor is observed to deviate from a required line a backspace switch 90, 98 is operated which results in the motors being driven by plotting control 92 to the position represented by the newest stored data in temporary store 84. The sensor is stepped back until it returns to a point on the line, the motors then being again driven under the control of the line following control 34. As described if a line is being detected by the sensor 24 when the outputs of encoders 35, 36 are sampled, the sampled position is stored. A magnified image of the line sensing device and a portion of the line around it is produced on the screen (38, Fig. 1, not shown) on a closed circuit television system so that an operator may observe when the sensor has deviated from the line or started to trace a branch line and switch the apparatus from its digitizing mode to its backspace mode by reversing switches 88, 90 to disable the line following control 34 and enable the plotting control 92 and by operating backspace switch 98 to transmit positional data from the store 84 to the plotting control 92. The data transmitted to the control 92 is deleted from the store 84, backspacing continuing until the sensor is on a point on the line when the apparatus is returned to its digitizing mode. The line following control 34 may be as in Specification 1,192,987.

Abstract: 316,243. Bilantz, D. S., and Watts, P. T. April 26, 1928. Brakes. - Automatic stop mechanism of the kind operated by a cessation or change in the feed movement of the tone-arm has a first member or lever 1 moved by the tone-arm and a second member or lever 2 carried on the first member and driven by the motor mechanism to move synchronously with the tone-arm during playing, but adapted, upon cessation or change of movement of the tone-arm, to move in a path which is other than parallel to the path of movement of the tone-arm to operate mechanism causing a brake to be applied. The Figure shows the position of the parts during playing. The lever 1, moved by the tone-arm about the pivot 1', carries on a pivot 3 a lever 2 driven by a pinion 6 from the motor. The levers 1, 2 move synchronously about the pivot 1<1> until the tone-arm stops or changes its movement when the lever 2 moves relatively to the lever 1 about its own pivot 3 and by its projection 2<11> operates a lever 19 to release a trigger 17 retaining the arm 13 of the three-armed brake lever 13, 14, 12. This allows a spring 28 to move the brake lever, the arm 14 of which applies the brake 21<2> whilst the arm 12 moves the pinion 6 out of engagement with the rack 5 on the lever 2. The brake is removed to start the machine by a projection 24 on the lever 1 which is swung across when the tone-arm is moved to starting position. The pinion 6 is driven from the motor by a spring drive and a spring tends to return the pinion to the bottom of the groove 8.
