Abstract: 319,735. Soc. Franþaise Radio Electrique. Sept. 27, 1928, [Convention date]. Electromagnetic current and pressure meters; frequency, inductances, and capacities, measuring . -An instrument of the dynamometer type for alternating current has a short-circuited coil movable in the fields of two independent electromagnets, the position of equilibrium being determined by the ratio of the currents traversing the field winding. The principal is illustrated in Fig. 1, in which the moving member is a. short-circuited coil 5 free to move laterally within the oppositely directed fields of two alternating-current electromagnets 1, 2 energized by windings 3, 4. The coil 5 takes up a position of equilibrium such that the total flux passing through it is zero, the position being dependent only on the ratio of the strength of the magnetic fields. The electromagnets 1, 2 may be mounted between brass plates 6 connected by pivots 7 so as to form a closed circuit opposing direct passage of flux between the electromagnets 1, 2. The coil 5 may be arranged to turn about its axis instead of moving laterally. Frequency may be measured by connecting the windings 3, 4 in series and shunting one with a condenser so as to form a circuit resonant to a frequency below the lowest to be measured. A frequency meter for a small range may be constructed by shunting both windings 3, 4 with condensers so as to form two tuned circuits one resonant to a frequency slightly lower than the lowest to be measured and the other resonant to a frequency slightly above the highest to be measured. Inductances, capacities or impedances may be compared by shunting them across the windings 3, 4 respectively, which are connected in series. Fig. 6 shows an instrument having a moving system free to move about two rectangular axes as described in Specification 316,298, [Class 40 (iii) , Telegraphs, Electric].

Filed: 1964-08-06
Abstract: 1,011,992. Electric selective signalling. R. T. HOOD, and D. R. STUETTIG. Aug. 6, 1964, No. 32133/64. Drawings to Specification. Heading G4H. An analogue-digital converter has support means, adapted to fit over a register (e.g. a utility meter) having a plurality of output shafts, in order to digitize the angular positions of the shafts, the support means bearing for each shaft a set of concentric annuli of segments detectable by means adapted to be connected to the respective shaft, and at least one of the sets having a further annulus of segments to provide an indication of whether the digit represented by the corresponding shaft is in the high portion or the low portion of its range. In the particular embodiment, two effectively identical sets of annuli are provided connected in paralell for digitizing each shaft, in case of poor electrical connections by the electric contact brushes constituting the segment detecting means. Each set of annuli provides a Gray binary coded representation of a corresponding decimal order. The said further annuli (one provided in each set) each comprise segments centred on alternate inter-digit boundaries each segment having an angular width equal to that between two adjacent inter-digit boundaries, and are used in an unspecified manner to correct slight angular errors, e.g. a reading of 0590 will be interpreted as 0490 if the 5 is in the lower portion of its range.

Title: Parallel adder with fast carry network
IPC: G06F7/52
Filed: 1962-08-15
Abstract: 965,830. Electric digital multiplying- apparatus. SPERRY RAND CORPORATION. Aug. 15 1962 [Aug. 17, 1961], No. 31266/62. Heading G4A. A shifting parallel adder of the type in which each stage can transfer its contents to another stage to be added therein to a digit of an input number has means for transferring carry signals either to a higher stage or the stage in which the carry originated depending on the type of carry. The arrangement is described as applied to a fast decimal multiplication circuit for multiplying two multi-digit decimal numbers and comprising six decimal adder stages, the contents of which are shifted one place to the right at each step of the multiplication and added to an appropriate multiple, depending on the particular multiplier digit of the multiplicand, this multiple being applied in parallel from a circuit 18, Fig. 1b, to the stages 1-6 of the adder. The product digits are shifted out successively, commencing with the lowest order, from an output 166, Fig. 1a, where they can be applied to a storage register (not shown). Multiplication by an n digit multiplier is completed in n + 1 steps, the final step being required for the addition of the final carries. Each stage (except the highest) of the adder comprises a "matrix half-adder" 22 (Fig. 2, not shown) for adding two decimal digits, one from the next higher order stage and the other from the multiplicand multiple circuit 18, Fig. 1b. The matrix half-adder 22 produces, as a sum output, a decimal digit 0-9 represented by a signal on one of a set of 10 leads 46 and possibly a carry output on a lead 78 which is added by a "unit matrix half adder" 36 in the next higher order to the sum output of the matrix half adder 24 of that order. If the addition of a carry produces a second carry called "ripple carry", an output is fed back by a lead such as 126 to the matrix half adder from which the ripple carry originated to be added during the next step of the multiplication to the sum output of the right-shifted partial product digit and multiplicand multiple digit. Final carries. When the multiplier digits have all been effective, a final operation step is necessary to add in the "final carries". During this step, a "final carry" circuit 200, Fig. 1d (and Fig. 4, not shown), receives the "ripple carry" outputs from stages 2-5 and outputs from any stages which have produced a partial product "9", and generates final carry signals 3FC-6FC which are applied "unit adders" 146-152 in stages 3-6 of the adder to produce the final digits for those stages.
