Abstract: 1,009,862. Commutation arrangements for dynamo-electric machines; control of several A.C. motors. DOWTY ROTOL Ltd. Nov. 13, 1962 [Nov. 29, 1961], No. 42702/61. Headings H2A and H2J. [Also in Division G1] A commutatorless motor has a permanent magnet rotor 12 and a position sensing device 14 coupled to rotor 12 which supplies a continuously varying signal to an amplifier 16 whose output, comprising square waves of voltage with variable mark to space ratio, is supplied to motor stator windings 20, 21, 22. The position sensing device, shown in Fig. 2, has one stator with windings 32, 33 fed with a reference A.C. signal and a second stator having a three-phase output winding in which a signal is induced corresponding to the position of the rotor. This signal is fed along wires 17, 18, 19 to amplifier 16 to provide the required currents in the motor stator windings. The torque of the motor may be maintained constant at all speeds by adding a voltage that increases with speed into winding 33 by means of drag-cap generator 34. Alternatively a modulator whose output is proportional to the speed of the motor may be used in place of the drag-cup generator or thirdly a permanent magnet three-phase generator driven from the shaft of the motor may replace the position sensing device. If the torque is required to be varied the body of the sensing device or generator is rotated relative to the motor body. In a further modification the variation of torque may be done electrically by modifying the system shown in Fig. 2 by adding a further pair of stator windings fed from modulators which are supplied with the output of the dragcup generator and an external control signal. The amplifier used comprises three-phase sensitive rectifiers which provide the position signals used to control the mark to space ratio of the output of the square wave generators supplying the multi-phase stator windings of the motor through a final power stage. The system is used in a fuel flow proportioning system where a number of motors are required to be run at the same speed as a master motor. Specification 986,100 is referred to.

[Also in Divisions D1-D2] In Fig. 1 the driving drum 7 engaging a yarn package 8 is connected to a drive-motor 10 through a clutch 14; when this is engaged bevels 12, 15 are also engaged to drive rollers 4 in the take-off direction. When a feeler 3 detects a fall in tension in the yarn, a solenoid 20 is energized to separate the clutch and engage bevels 13, 17 so that the direction of rollers 4 is reversed. In Fig. 2 (not shown), a drum (22) is continuously driven. Rollers (24, 28) are geared to it so that they rotate in opposite directions. During normal working, a roller (23) mounted on a pivoted arm nips roller (24) to withdraw the yarn. When the tension falls, solenoids (30, 31) are energized; solenoid (30) transfers roller (23) to roller (28) so that the yarn is fed back, and solenoid (31) causes a brake to engage and lift the package off the drum. In Fig. 4 a roller 36 on a pivoted arm and coupled to one of a pair of  yarn withdrawing rollers, engages a continuously-driven roller 34. When, the roller 36 is transferred from roller 34 to the inner surface of a segment connected to roller 34, the withdrawing rollers are driven in reverse and at a faster speed. In Fig. 5 (not shown), nip-rollers (45, 46) are driven in yarn withdrawing-direction from a continuously-driven shaft (51), roller (46) being coupled with a larger roller (49) spring-urged into contact with the shaft, and roller (45) being spring-urged away from the shaft. When roller (45) is moved on to shaft (51), thereby forcing roller (49) away from the shaft, is Lriven faster and in the reverse direction.

Abstract: 1,261,505. Film processing simulation apparatus. HAZELTINE CORP. 17 Sept., 1970 [26 Sept., 1969], No. 44402/70. Heading H4F. Film processing simulation apparatus which electronically simulates the "exposure to density" conversion that occurs in the photochemical processing of film and which is switchable to simulate different such conversions for different classes of films, comprises a plurality of selectable (in dependence upon the film class) linear transfer circuits (two shown at 11 in Fig. 1) to which is supplied 12 the input signal representative of film exposure (e.g. derived by scanning a transparency), the resultant signal at terminal 13 (determined by the particular film being simulated) being supplied via a non-linear amplifier 15 to a second plurality of selectable linear transfer circuits 34 each similarly corresponding to a different film class (two circuits shown). An output signal is thus developed at 35 whose instantaneous amplitude is representative of the resulting density of the processed film and corresponds to a film exposure represented by the corresponding instantaneous amplitude of the input signal at 12 thereby simulating the exposure to density conversion which occurs in the processing of the film. Only one non-linear amplifier 15 is used, but depending on which linear transfer circuit is operational (e.g. attenuated by potentiometer 14 or unattenuated over wire 16) different prescribed regions of the transfer characteristic of non-linear amplifier 15 are operational on the signal at terminal 13. Amplifier 15 has an approximately logarithmic. transfer characteristic (Fig. 2, not shown) and with ganged switches 17 and 40 in the positions shown only the lower region of its characteristic is used. In the other position of ganged switches 17 and 40 the overall transfer characteristic of amplifier 15 is used, the signal at terminal 13 being unattenuated, and the output is fed via an inverting circuit (180 degrees phase shifter) 38 and a potentiometer 39 to output 35. Colour film processing simulation apparatus includes three such channels in parallel, one for each primary colour, somewhat as described in Specification 841,125.
