Title: Synchronous capacitor for providing reactive power, particularly when load surges occur
IPC: H02J3/18
Filed: 1961-06-22
Abstract: 933,990. Automatic power factor control; induction generators. BROWN, BOVERI & CO. Ltd. June 22, 1961 [June 24, 1960], No. 22674/61. Classes 35 and 38 (4). The power factor of an A.C. supply system is controlled by automatically controlling the phase and amplitude of the current supplied to the wound rotor of an asynchronous motor, the stator of which is connected to the supply system. The required active component of rotor current (to overcome losses) is computed by measuring the rotor speed by means of a D.C. tachometer generator 8, comparing the speed signal with a reference signal at 12a and modulating the error signal at 13 to produce a 3 phase error signal at mains frequency. This signal is in turn modulated at 14, 15, 16 by the output of an A.C. tachometer generator 9 to provide at 14d, 15d, 16d a 3-phase error signal at slip frequency. The required reactive component of rotor current is computed by multiplying at 17 the outputs of current transformers 5 and potential transformers 6. The transformers are paired off appropriately to provide a 90 degrees phase shift of the voltage signal with respect to the current. The reactive V.A. signal from multipliers 17 is compared at 18a with a reference signal and the resulting error signal is modulated first to 3 phase mains frequency at 19, and then modulated at 20, 21, 22 to provide a 3 phase slip frequency signal at 20d, 21d, 22d. The computed active and reactive rotor current signals are now combined in an undisclosed manner at 70 and compared at 23a with the actual rotor current, measured by current transformers 7, and the resultant is used to control, in an undisclosed manner, the reversed pairs of rectifiers 2 that form a frequency converter for supplying the rotor of the motor at slip frequency from the supply mains. The rectifiers 2 may be grid controlled valves (as shown) or silicon-controlled rectifiers, Fig. 1 (not shown).

Title: Method and apparatus for determining the supercompressibility factor of natural gas
IPC: G01F15/04
Filed: 1971-04-19
Abstract: 1317344 Measuring supercompressibility factor electrically DANIEL INDUSTRIES Inc 19 April 1971 [18 March 1970] 22850/71 Heading G1N Apparatus for determining the volumetric flow rate of natural gas in a pipe 10 includes means for compensating the rate for the supercompressibility factor Fpv of the gas which factor represents the diviation from the ideal gas laws. The squared supercompressibility factor is given by: Fpv<SP>2</SP> = P s F(P)F(G)F(T) + K 1  where P s  is the gas static pressure, F(P)F(G)F(T) are functions of pressure, specific gravity and temperature respectively and K 1  is a constant. The flow is measured conventionally using an orifice plate 12,14, differential pressure h transducer 16, and gas temperature transducer 28, 29 and the rate calculated in a computer 32. Gas pressure P s  is measured by a transducer 26 and signalled to a first multiplier 100 and to a summing circuit 112. A second temperature transducer 30, 31 monitors downstream gas temperature and provides to a second multiplying circuit 102 a signal representing the temperature function F T  which controls the gain of an amplifier 122 so that the output signal at 110 represents the product P s F(P)F(G)F(T), the functions F(P)F(G) having been predetermined by choice of resistors 118, 119, 121 and by adjustment of potentiometer 108. The constant K 1  is set by potentiometer 124 to D.C. source 123 and the product on 110 is combined with the constant by summing amplifier 126. The sum at 40 is then led to multiplying circuit 114 to yield the product P  A F pv 2 where P A  is gas absolute pressure and is determined in circuit 112 by addition of the signal representing P s  and a signal representing barometric pressure, P B . A signal representing the product P A F pv 2 is led to the computer 32 which produces a signal representing the gas flow rate in standard cubic feet Q SCF,  that is, compensated according to the expression: where Q<SP>1</SP> ACF  is the measured or actual (uncompensated) flow rate and T is absolute temperature of the flowing gas. Typical values for the squared supercompressibility factor F pv 2 of natural gas with an average specific gravity 0À6, in a range of temperatures 30‹F. -90‹F. and at pressures of between 500 and 900 p.s.i., lie between 1‹0675 and 1À2085. In an alternative embodiment Fig. 2 (not shown) the actual flow rate is measured by a turbine flow meter producing pulses indicative of gas flow.

Abstract: 683,982. Aerials. GENERAL ELECTRIC CO., Ltd., and FALCONER, J. M. Sept. 19, 1951 [Sept. 19, 1950], No. 23006/50. Class 40 (vii). An aerial system comprises a folded dipole connected across a coaxial feeder in combination with means for feeding heating current from a supply line into the coazial feeder and thereby to the dipole which may thus be resistanceheated, the said means being adapted to prevent any appreciable flow of R.F. energy from the feeder to the supply lines. In a first arrangement the folded dipole 1 is connected between the inner and outer conductors 2 and 3 of the coaxial feeder, the outer, 3, of which is gapped and provided with flanges 8 at some point along its length. The narrow gap between the flanges is filled with a layer of dielectric 9 and the heater current supply line 6 connected across the flanges. The heater current is completed by a coupling loop 7 at the end of the feeder distant from the aerial and the supply line 6 effectively short-circuited at high frequencies by the capacitor formed by the elements 8 and 9. In a second arrangement where there is no conductive circuit at the distant end of the feeder but only capacity coupling a stub line of a quarterwavelength long is connected into the coaxial feeder and the heater current supply lines fed across the inner and outer conductors of the stub. A capacity termination is provided for the stub which is thus made of high impedance to R.F. at its point of connection to the coaxial feeder, Fig. 2 (not shown). In another arrangement the heating current may be fed through H.F. chokes. The dipole may consist of a core of metal of appreciable resistance plated with a low resistance layer that, due to skin effect, will carry most of the R.F. current.

Abstract: 1,170,448. Testing apparatus for P.C.M. systems. MARCONI CO. Ltd. 3 Feb., 1967 [24 May, 1966], No. 23162/66. Heading G4H. A pulse code modulation system including testing apparatus for the encoder (Fig. 1), or the decoder (Fig. 2), comprises a first detector 6 (Fig. 1), 15 (Fig. 2) for detecting in normal transmission the occurrence of signals of a predetermined level applied to the input of the encoder or decoder, a second detector 5 (Fig. 1), 16 (Fig. 2) for detecting the occurrence of encoder or decoder output signals corresponding to input signals of the predetermined level and means 7 (Fig. 1), 17 (Fig. 2) for producing a fault indicating signal in the event of non- correspondence of the detected signals. In the embodiment described the encoder which is of the type in which the input signal is compared in a comparator 2 (Fig. 1) with a signal from a level synthesizer 3, the output from the comparator being fed to logic circuitry 4 controlling the synthesizer 3, the binary coded output from the comparator 2 is fed through an AND gate 9 enabled by a fault code generator 8 when there is coincidence of signals to the comparator 7. If, however, the level detector 6 gives an output when there is no output from the detector 5, the AND gate 9 is disabled and an error signal is transmitted. At the decoder, in which the binary coded signal transmitted on lead 12 is converted into an analogue signal and transmitted by a gate 19, a fault code detector 18 detects incoming signals corresponding to a fault indicating signal to disable the gate 19. The gate 19 is also disabled when there is non- coincidence of signals to the comparator 17. Multiplexing arrangements may be included at the input 1 (Fig. 1) of the encoder and at the output 20 (Fig. 2) of the decoder.

Abstract: 1397492 Watches CITIZEN WATCH CO Ltd 16 May 1973 [16 May 1972 (2) 31 March 1973 (3) 19 April 1973] 23310/73 Heading G3T A watch has a winding/setting stem 1 adjustable to four axial positions, in one of which rotation of the stem adjusts the regulator of the watch. In the inner, winding position, Fig. 1 (not shown), pinion 3 on the stem transmits rotation via wheels 4 and 7 to a winding wheel (15). When the stem is pulled out to its next position, Fig. 2, lever 6 is rocked so that wheel 8 thereon comes to mesh with a wheel 22 pivotally mounted on a further lever 18 which is also rocked by a cam slot 20 in that lever co-operating with a pin 17 on setting lever 2. Rotation of the stem then drives the pinion 3 and wheels 4, 8, 22, 23 to advance a date ring 28 and a day calendar via a connection lever 25. In the third stem position Fig. 3 (not shown), the wheel 8 meshes with a setting gear 30 which can thus be rotated to drive minute wheel 31 and cannon wheel 32 to set the hands. On pulling the stem to its fourth, outermost position, the lever 6 is allowed to return slightly so that the wheel 8 is unmeshed from gear 30 and the pinion 3 meshes with a wheel 46, Fig. 5, which in turn meshes with a wheel 43. The latter engages a toothed sector 45 on a lever 44 the other end of which is forked and embraces the arm of a regulator 47. The regulator may thus be adjusted over a limited range. An alternative embodiment is described having a longer gear train to the regulator, automatic winding, and a lever (52), Fig. 7 (not shown) carrying a spring (51) to arrest the balance (50) in the hand setting position of the stem.

If either of the primary fluid supplies falls below a pre-selected pressure, one or other of valves 28, 34 selects an auxiliary supply provided by a pump 58 and a reservoir 62. In the valve 28, Fig. 2, pressure fluid from the pump 39 passes through lines 124, 126 to the servomotors and is also applied to areas 130, 132 on the end of a spool 110 through a line 124b. Pressure fluid from the auxiliary pump 58 is applied to area 138 of the spool 110 through a line 136a. This pressure fluid may also act on area 140, but because the areas 138, 140 are smaller than areas 130, 132 and the pressures are similar, the spool remains in the position shown. If pump 39 fails, the spool moves to the right and a land 118 closes line 124, 126a between the pump 39 and the servomotors and a land 115 opens a line 136b, 126b from the auxiliary pump 58 to the servomotors. Valve 34 operates in the same way and the auxiliary pump can take over from either or both of the primary pumps.
