[Class 37.] One half-wave of an alternating current is varied in accordance with one measured value and the other half-wave is varied in accordance with a second measured value, the positive and negative half-waves being supplied to separate receiving instruments. Resistances 13, 14 are connected in series with opposed rectifiers 18, 20, so that one-half wave of alternating current from a generator 10 is varied by the resistance 13 in accordance with one quantity to be measured, e.g. the effective output and the other half-wave is varied by the resistance 14 in accordance with the other quantity, e.g. the wattless output. The resistances 13, 14 are connected in parallel with each other and in series with a transmission line connected at a distant station to two indicating instruments 16, 17 in parallel circuits containing opposed rectifiers 19, 21, so that the half-wave controlled by the resistance 13 is measured on the instrument 16 and that controlled by the resistance 14 is measured on the instrument 17. A thermal or other quadratically acting instrument 15 is connected in the common transmission line and indicates the sum of the squares of the effective and wattless output, i.e, the square of the apparent output. The instruments 15, 16, 17 and the rectifiers 19, 21, may be arranged in a common casing. The rectifiers are preferably dry rectifiers. Meters or recording instruments may be employed instead of, or in addition to, indicating instruments. Instead of resistance transmitters, regulating arrangements may be employed which each adjust a current proportional to the measured value.

Filed: 1952-02-19
Abstract: 696,742. Copying machines. SENECA FALLS MACHINE CO. Feb. 19, 1952. No. 4397/52. Class 40 (i). [Also in Group XXII]. A machine tool is equipped with pattern control mechanism comprising opposed torque motors and normally open or normally closed switches controlled by a rotating cam or eccentric. In the copying-lathe shown, Fig. 1 a spring-controlled stylus 31 pivots at 41 clockwise or anti-clockwise Fig. 2 from normal mid-position as it follows the contour of a templet 30 with traverse of cutting tool T lengthwise of work W and a cam or eccentric 72 continuously driven by a motor M2 Fig. 3 functions to open either switch 55 or 57 so that a corresponding torque motor M or M1 is released whereby the other motor operates to turn feedscrew 38 to move the guide plate 21 and thus the cutting tool T towards or away from the work W and also post 43 supporting the stylus assembly until with return of the stylus to midposition the switch 55 or 57 is closed and the opposing torque motors M, M1 again neutralize one another. The stylus 31 is mounted on a T shaped member 40 pivoted at 41 in a frame 42 supported by post 43 and the normally closed switches on this T-piece comprise rigid plates 50, 51 and flexible plates 52, 53 which latter extend upwards and are terminated by insulating pads 70, 71 normally spaced apart slightly less than twice the greatest radius of the cam or eccentric 72. With displacement of the stylus 31 the eccentric 72 during a part of each revolution encounters or engages one of the pads 70 or 71 to open the corresponding switch and the switch open period is dependent on the extent of the stylus displacement. In a modification Fig. 4 (not shown) the switches are normally open and as one or the other is closed by the rotating eccentric so a corresponding relay is operated to open the circuit of one of the motors.

IPC: G11C11/06
Filed: 1960-02-08
Abstract: 973,803. Circuits employing bi-stable magnetic elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 3, 1961 [Feb. 3, 1960], No. 4397/60. Heading H3B. Each column of a magnetic storage matrix has associated read and write conductors RC1, WC1, Fig. 1, which are connected through transistors TR1, TW1 or rectifiers to control windings w1 on respective read and write magnetic driving cores CR1, CW1. To read a selected column of storage cores, the associated driving cores are first brought into the set state by a selector pulse applied to windings w3. Coincident drive and read pulses are then applied to respective windings w1 and w2 on core CR1, the read pulse resetting the core and thereby inducing a pulse in w1, which aids the drive pulse to an extent sufficient to cause switching of the column storage cores. Output pulses are produced in those row conductors R1 which are associated with switched storage cores, these outputs being either fed back after a delay as half-write pulses or fresh information introduced. Coincident with the half-write row pulses, the core CW1 is switched by write and drive pulses in windings w1 and w2, the core being reset and augmenting the drive pulse sufficiently to effect coincident switching of selected column storage cores. Further details are shown in Fig. 2 in which matrix columns 1, 2 and 3 have respective pairs of driving cores CR1, CW1; CR2, CW2 and CR3, CW3, each pair being set in turn by a stepping circuit comprising cores CQ1, CQ2 ... and transistors TQ1, TQ2 ... under the control of clock pulses, so that the reading and writing operations take place column-by-column. The delayed writing pulses from the row read-write apparatus may be produced by blocking oscillators as described in Specification 903,094. In the case of a three co-ordinate store, operation of any matrix plane may be prevented by an inhibiting potential applied to terminal PS. 5
