Title: Electric wave filter
IPC: H03H7/01
Filed: 1921-07-14
Abstract: 186,198. Western Electric Co., Ltd., (Western Electric Co., Inc.). July 14, 1921. Filter circuits.-Relates to filter circuits of the general type described in Specification 142,115 comprising sections each containing impedance in series and impedance in shunt. According to the present invention, the typical circuit, Fig. 1a, disclosed in the above-mentioned Specification is modified into a typical circuit of the form shown in Fig. 2, by interchanging the lumped impedances respectively in series and in shunt to the line. The result is in general to secure a sharper discrimination between the frequencies transmitted and those suppressed. The filter shown in Fig. 2 suppresses all frequencies between two limiting values while transmitting all frequencies outside these limits, but it may be modified, by omitting certain elements of the impedance network, to produce (a) ultra-filters that will suppress all frequencies higher than a definite value, and (b) infrafilters that will suppress all frequencies below a specified limit. Fig. 6 represents a series of characteristic curves for infra-filters of the type shown in Figs. 7 and 8, the ordinates representing the attenuation of the current per section of filter, and the abscissae showing current-frequencies. In each curve the attenuation of the current by the network increases to a practically infinite value at a definite frequency which is not zero. The transmitted frequencies are those lying to the right of the point f3. By suitably adjusting the values of inductance and capacity the band of transmitted frequencies may be terminated more or less abruptly, the right-hand curve showing a sharp cut-off. The dotted-line curve is characteristic of a known form of infra-filter described io the above-mentioned Specification. The infra-filter shown in Fig. 7 is developed from the typical circuit of Fig. 2 by making the inductance L1 infinite (i.e. by omitting it and leaving the circuit open); in Fig. 8 the capacity C2 is made infinite by omitting it and closing the circuit at that point. Figs. 9 and 10 show ultrafilters similarly derived from Fig. 2 by making the capacity C, and inductance L2 respectively equal to zero. The Specification sets out mathematical formulae for determining the dimensions of the impedances in order that any desired band of frequencies may be transmitted or suppressed, including the consideration of an additional impedance element which is designed so that a finite filter may behave as nearly as possible like a filter of infinite length.

Title: Electrostatic gyroscope suspension system

Filed: 1972-04-25
Abstract: 1368037 Gyroscopes ROCKWELL INTERNATIONAL CORP 25 April 1972 [21 May 1971] 19231/72 Heading G1C [Also in Division G3] In a system for suspending a gyroscope rotor centrally between a plurality of opposite pairs of electrodes by regulating the charge applied the electrodes according to the voltage upon them (and hence according to rotor displacement), build up of charge on the rotor is prevented by periodically applying alternating polarity pulses of standard amplitude to the charging means. Fig. 4A and B shows the charge applied to each of a pair of electrodes respectively during one complete cycle of a switching sequence of, e.g. 100 microseconds. Qp is the standard charge which is  applied alone at T3 and T7 and to which a charge Qs proportional to rotor displacement is added and subtracted respectively during T2, T4, T6, T8 to centralise the rotor. Each electrode is charged by an amplifier 61 until the voltage across a series capacitor 66 equals that applied to amplifier 52, which corresponds to that applied to amplifier 38. Since the capacitance of 66 is constant the charge on it, and hence the charge applied to the electrode depends only upon the voltage applied to 38. Qp is produced by a voltage source K1 Qp and -K1 Qp applied to 38 while Qs is derived by a circuit Fig. 3A (not shown) in which the voltage at the output of 61 and hence that on each pair of electrodes is periodically sampled at times T3 and T7. In the embodiment four pairs of electrodes are used and the signals from these transformed into those appropriate for three orthogonal planes, these signals being passed through notch filters used for controlling the rotor speed as in Specification No. 1324458 and "servo networks" which stabilize the system in an unspecified way and are re-converted back to four signals which are the required displacement voltages K1 Qs and -K1 Qs. Switches SW1... SW6, Fig.3B are operated in the necessary sequence to combine the voltages in the way required for Fig.4. Resistors 67 and 68 are chosen to give the same time constant to both parts of the circuit when the rotor is centred.
