Title: Apparatus for and method of determining rotational or linear stiffeness
IPC: B25B23/145
Filed: 1972-05-09
Abstract: 1434726 Driving screw fasteners STANDARD PRESSED STEEL CO 30 April 1973 [9 May 1972] 21480/72 Heading B3N [Also in Division G1] Apparatus for driving screwed fasteners comprises output means 2 for rotating a screw 1, driven input means 8, deflectable coupling means 11 for transmitting power from input to output, a first displacement encoder 9 producing pulses (# 1 ) corresponding to rotation of the input means 8, a second displacement encoder 6 producing pulses (# 2 ) corresponding to rotation of the output means 2 and comparator circuitry (Fig. 4) for determining the difference between the number of # 1  and # 2  pulses during a predetermined number of # 2  pulses, and means for stopping the drive or maintaining a constant torque when the difference has dropped to half its maximum value. The measured value is the gradient of the torque-angle curve dM/d# 2  and equals K(## 1 -## 2 )/(## 2 ). Pulses 91 are fed to an up input of counter 25 and pulses # 2  to a down input of counter 25 after a direction check at 28. This prevents measurement if encoder 6 is rotating backwards under the influence of driven member 1. Pulses # 2  also enable gate 29 which passes the content of counter 25 (0 or 1) to gradient register 26, to shift register 27 and to count down counter 25. Shift register 27 is clocked by pulses # 2 , its capacity the predetermined number of # 2  pulses and its output is fed to the gradient register 26. The value in gradient register 26 is the continuously updated torque gradient.

Title: Improvements in alternating-current dynamo-electric machines
IPC: H02K19/36
Filed: 1921-08-15
Abstract: 187,377. Townend, R., Kuyser, J. A., and Metropolitan - Vickers Electrical Co., Ltd. Aug. 15, 1921. Exciting; pole - pieces; armatures and field-magnets, short-circuited coils on poles of.-To prevent excessive increase of voltage in an alternator due to armature reaction when the machine is charging a longdistance high-tension transmission line or other leading-current load, the core is given an initial magnetic saturation during the charging period, the normal flux density being subsequently restored. In the form shown in Fig. 1, each of the rotating magnet poles is made in two parts 2, 3, the coils 4, 5 of which, in normal running, carry equal independent currents and act as a single pole. When the machine charges the line, the current in one coil is reduced so that a part of the flux passes from one part of the pole to the other and the effective flux cutting the conductors in the stator 6 is reduced, saturation occurring at a correspondingly lower stator voltage. The current in one of the coils may be reversed, and the pole may be divided into more than two parts. The currents in the exciting coils may be regulated in accordance with the desired manner of charging the line. Alternatively, in a normal multipolar machine, some of the poles may be reversed during the line-charging period by means of switch gear and extra slip-rings. The saturating flux may also be produced by a separate winding 8, Fig. 2, which is supplied with continuous-current during the charging period. This winding may be wound partly in the slots 9 which carry the generating coils of the machine, or it may be entirely in special tunnels independently of the main coils. In stators with axial ventilation, the auxiliary winding may be partly placed in the vent tunnels. Fig. 4 shows the use of loops or coils 12 wound in tunnels 13 in the stator 6 and having switches 14 by which they are shortcircuited during the charging period so as to damp out the alternating flux in those parts of the stator which are embraced by the loops, and limit its path to a small part of the core which accordingly becomes saturated at a low voltage. In Fig. 5, the saturating flux in the stator is of circumferential form and is produced by passing a continuous-current from a source 18 through the mass of the rotor 7 by means of slip-rings 15 additional to the rings 19 used for the normal rotor excitation.
