Title: Improvements in and relating to torque or power meters
Inventor: HUMPHRIES WALTER JAMES ARTHUR
IPC: B41F33/14
Filed: 1948-06-04
Abstract: 644,234. Electro-dynamometers. MINISTER OF SUPPLY. June 4, 1948, No. 15089. [Class 40 (i)] [Also in Group XIX] A dynamometer of the type transmitting electric signals from pick-off devices 12 located at spaced points along a shaft 11 is calibrated directly to indicate torque or power instead of the phase relationship of the signals obtained. The shaft 11 with the rotors of the pick-off devices fast thereon is held stationary by means 13 and is loaded by means of a detachable scale pan 16 and weights to produce a known deflection. The stators 17 of the pick-off devices are rotated around the shaft 11 by mounting the housing 18 on a suitable bearing 19 on the shaft 11. An electric motor 20 and belt 21 are employed to rotate the housing 18, and slip rings 23 are mounted in a stationary housing 24 mounted on the shaft 11 so that in conjunction with brushes 22 and 25 the signals produced may be taken to the indicating device, not shown. To calibrate the device the shaft 11 is held stationary and the stators rotated in their housing 18 with no static load on the shaft to obtain a zero reading. Successive known deflections are applied to the shaft by means of weights placed in the removable scale pan 16, and the indicating device calibrated accordingly in terms of deflection or power. In operation the locking device 13 is released and the scale pan 16 removed. It is not necessary, however, to hold the stator carriage stationary, it may be rotated whilst measurements are being made, in the same or opposite direction to that of shaft 11, in order to extend the range of speeds over which the apparatus may be employed, and to produce accurate readings at low or zero speeds or at very high rotational speed without extending the range of frequencies at which the phase relationship of the signals may be compared accurately, and by variation of the speed of rotation of the carrier 18 the frequency of the signals from the pick-off devices may be adjusted for maximum response to changes in phase relationship.

Filed: 1947-06-12
Abstract: 658,246. Automatic control systems for aircraft. SMITH & SONS (ENGLAND), Ltd., S. June 12, 1947, No. 15565. [Class 38 (iv)] In an automatic control system a condition is maintained at a datum by signals in accordance with both the rate of deviation from the datum and the duration of the deviation. As shown, Fig. 1, the aircraft aileron 6 is automatically positioned through a system, which is a modified form of the system described in Specification 617,240, by the motor 19, described in Specifications 576,248 and 576,249, in response to signals from the rate of roll gyro 5 and the pendulum 7 to stabilize the craft about the roll axis. During roll, the tapping 39 is positioned on potentiometer 40 by the precessional movement of gyro 5 and the phase sense of the resultant A.C. output signal corresponds with the direction of roll. Similarly, the pendulum 7 produces a signal at the potentiometer 45 which is applied to the winding 55 of the motor 54 which rotates at a speed and in a direction corresponding to the roll angle to set the potentiometer tapping 48 in accordance with the time integral of the roll deviation. The three signals are applied in series to the amplifier 21 together with the output of the generator 22 as described in Specification 576,351, which is driven by the motor 19, and energized from the amplifier. During roll, the signals from 22 and 40 predominate and the aileron moves at a speed proportional to the rate of roll, while after a disturbance, the craft is levelled on the roll axis by the monitoring action of the pendulum 7. In a second embodiment, not shown, the tapping 48 is positioned in accordance with the duration of deviation.

Abstract: 634,408. Adjusting internal-expanding brakes. PARKER, H., and ROWLAND, T. C. E. June 18, 1947, No. 16095. [Class 103 (i)] An automatic adjusting device for a twin shoe internalexpanding brake comprises a composite strut of adjustable length supported by bearing surfaces at its ends coacting with a brake shoe and a rocker member for displacing the strut and means mounted on the strut, and operatively connected to the rocker member, for moving its composite parts endwise relatively to each other to increase its length, the said means being actuated when excessive relative angular movement between the rocker member and the strut takes place. In the embodiment shown, recesses 31 in a rocker member 14 engage the inner ends of two variable struts. These latter comprise housings 15 enclosing screwed sleeves 17, one of which is rotated by a worm shaft 19 and the other by a flexible cable 32 extending through the member 14. Rotation of the sleeves 17 causes inner screwed members 16 to extend, thus reducing the clearance between the linings 22 and the drum 20. A pawl 23 having lost-motion connection with a ratchet-wheel attached to the worm-shaft 19 is carried by a lever 25 mounted for independent rotation on the said worm-shaft and connected by a link 26 to a lug 27 on the rocking member 14. Excessive angular displacement of the rocking member 14 relatively to the strut due to wear on the linings 22 causes the pawl 23 to slip a tooth during application of the brake and thus initiate an increase of strut length on release of the brake. Specifications 446,339, 456,238 and 479,499 are referred to. Specification 492,880 also is referred to in the Provisional Specification.

Particles, e.g. of 5 to 50 microns, are graded according to size by placing them in the uppermost of a series of superposed sieves with apertures decreasing in size progressively downwards and oscillated the sieves while a current of liquid is flowed through them. As shown, removable sieves 11 are mounted on a pillar 10 which is oscillated about a pivot 15 on a support 12 by means of a crank 16 and connecting rod 17 drived by a motor 18. The motor also drives a pump 19 which delivers liquid, e.g. acetone, from a reservoir 21 through a flexible tube 22 to the uppermost sieve in the form of a spray. A funnel 23 is provided below the sieves to deliver the liquid into a filter 24 from which it returns through a syphon 27 to the reservoir 21. A pipe 25 connected to the tube 22 communicates with a suipply of compressed air which may be heated. A timer 26 controls the operation of the motor 18 so as to switch off after a predetermined period of grading and also controls the supply of air so as to switch it on for an appropriate period to dry the graded particles. An air vent pipe 28 may be provided for each sieve to facilitate circulation.
