Title: Improvements in admittance measuring apparatus
IPC: G01R27/02
Filed: 1963-06-12
Abstract: 1,013,078. Measuring bridges. BOONTON ELECTRONICS CORPORATION. June 12,1963 [June 20,1962], No. 23438/63. Heading G1U. An admittance measuring apparatus comprises first and second input terminals 8 and 9, Fig. 2, and a common chassis terminal 7 adapted to receive A.C. voltages of opposite phase; an output detector terminal 16; a resistance and a capacitor connected in series between terminal 16 and each of the input terminals 8 and 9, at least one of the capacitors being variable; a null detector 15 connected between terminals 7 and 16; and test terminals connected to terminal 7 and to the junction of one of the resistances and capacitors. The circuit may be energized by an oscillator 10 and a centre-tapped transformer 11 and it is shown that with R1 equal to R2 and with Cz, Cs and Ls omitted, Fig. 1 (not shown) the value of an unknown resistance RU connected across terminals 20 and 21 when the bridge is balanced is equal to R1/C 2 /C R <SP>-1</SP>. The value of the unknown conductance or resistance may be read directly from a calibrated dial associated with the variable capacitor C R . In Fig. 2 C2 is also variable and is mechanically ganged to C R  to form a differential capacitor. When the unknown impedance includes reactance, a calibrated variable air capacitor Cs and an inductance Ls are connected across terminals 20 and 21 and tuned to resonance at the test frequency. With C R  set to indicate zero admittance Cz is adjusted to balance the bridge, thereby compensating for the effective resistance of the resonant tuned circuit. The unknown impedance YU is then connected to terminals 20 and 21, C s  re-adjusted to restore the circuit to resonance, and C R  adjusted to give the best null; in practice the optimum null is achieved by repeating the above adjustments of C R  and C s  several times. The reactance or susceptance of YU is read from a calibrated scale associated with C s  as the increase or decrease in capacitance required to re-tune to resonance, and the resistance or conductance is read from the scale associated with C R . At high frequencies the combination of C s  and L s  may be replaced by a resonant transmission line. The transformer 11 may be replaced by a vacuum tube phase splitter circuit.

Title: Digital encoders
Inventor: PETHERICK EDWARD JOHN
IPC: H03M1/00
Filed: 1955-08-15
Abstract: 808,564. Electric selective signalling systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 2, 1956 [Aug. 15, 1955], No. 23509/55. Class 40 (1). A digital encoder including a coarse commutator having thereon a plurality of tracks each marked with a succession of conductive regions and non-conductive regions in accordance with a predetermined code, intermediate output means co-operating with the tracks of the coarse commutator to provide a first set of electrical outputs dependent on the positional relationship between the intermediate output means and the coarse commutator, selector means and gear means for driving the coarse commutator at a speed relative to the selector means different from that of the intermediate output means to select from the first set of electrical outputs a final set of electrical outputs according to the position of the intermediate output means relative to a datum position on the selector means so as to indicate the said position of the intermediate output means. As described a digital representation of the angular position of a shaft 2, Fig. 1, rotatable through up to ten complete revolutions is obtained by means of two sets of brushes M1 &c. and A1 &c. (constituted by ball-bearings) which co-operate with two commutator discs 5 and 11 respectively. The brushes A1 &c. are carried by a member 13, fixed to the shaft 2 and are " twoended," the left-hand ends co-operating with fixed semi-circular slip rings on a member 14 (Fig. 4, not shown) and the right-hand ends (which are joined electrically with the left-hand ends) co-operating with the commutator 11 (Fig. 3, not shown) which is free on the shaft 2 and which is driven from the shaft 2 at nine tenths its speed via a gear 7, a pinion 9 and a gear 10 integral with the commutator. Thus for ten revolutions of the shaft 2 brushes M1 &c. make ten revolutions relative to the commutator 5 (Fig. 2, not shown), left-hand ends of brushes A1 &c. make ten revolutions relative to the fixed commutative slip rings, and righthand ends of brushes A1 make one revolution relative to commutator 11, and hence the device has a period of ten revolutions. A monophylic binary-coded monophylic decimal code is used and described in detail and the commutating discs and commutative slip rings are so arranged that slight errors in their positions, due to backlash in the gearing, have no effect on the shaft position indication produced. It is stated that the commutator 11 could be linear (as opposed to circular) in which form it could be adapted for indicating the position of a machine tool. Specification 762,284 is referred to.
