Abstract: 1362850 Controlling converters GENERAL ELECTRIC CO 9 Aug 1972 [16 Aug 1971] 37089/72 Heading H2F In an inverter of the type having at least one pair of series-connected controlled rectifiers across D.C. lines and quenched by a further series-connected pair of controlled rectifiers, the commutation current is monitored (e.g. by transformer 64) and further commutation is blocked for a period equal to a predetermined delay following the end of the commutation current. As described, Fig. 1 (not shown) relates to a three-phase inverter for supplying power to an A.C. motor. A commutation circuit comprising capacitor 46 and inductor 48 are connected between the junction 52 of the main controlled rectifiers and the junction 50 of the commutation controlled rectifiers. The commutation current is monitored by transformer 64, the output of which is fullwave rectified at 112. At the end of the commutation period, transistor 126 is turned off, allowing capacitor 142 to charge via resistors 131, 146 so as to give a predetermined delay before transistor 134 is turned on so as to feed a signal to a logic circuit (152) allowing further commutation to occur without causing simultaneous conduction of the two commutation controlled rectifiers in a series pair. The invention is applicable to a pulse-width-modulated inverter.

Abstract: <PICT:0922289/IV(a)/1> Apparatus for treating yarns comprises an autoclave with a support having perforated walls, therein associated with two centrifugal pumps for circulating liquid through the autoclave in two opposite directions, each pump being actuated by an independent motor, the motors being associated with means for making the pumps operative at alternating intervals.  In the embodiment shown, autoclave 1 having a cover 2 is fitted with a support device 4 for the material to be treated.  Centrifugal pump 5 driven by motor 7 through hydraulic coupling 8 is capable of circulating liquid through the material 3 from the inside to the outside whilst pump 6 similarly driven from another motor 7 is capable of circulating liquid through material 3 from the outside to the inside.  The starting of each pump and the stopping at predetermined alternating time intervals in order to reverse the direction of flow may be controlled manually or by automatic means.  The pumps are so constructed and dimensioned as to ensure that in a given time the quantities of liquid circulated in the two directions are equal.  A heat exchanger 9 may be fitted to the autoclave for heating or cooling the liquid therein and a centrifugal pump 10 may be provided for establishing a high head in the autoclave. For this purpose the pump 10 is connected to an expansion reservoir 11 and sucks a small quantity of liquid therefrom and forces it into the short duct between the orifices of the pumps 5, 6.  A valve 14 in duct 12 from the top of the autoclave to the reservoir 11 serves to control the pressure in the autoclave and any vapour or air collecting in the autoclave can escape via duct 12.

Filed: 1973-08-09
Abstract: 1423418 Radio frequency systems P HAAS 9 Aug 1973 [15 Aug 1972] 37857/73 Heading H4L Two spaced antennae are used to locate an illicit transmitter, despite the possible existence of a higher power but more distant (and legal) transmitter. Supposing both transmitters to transmit at the same frequency, and the field strength due to the legal one in the vicinity (e.g. a "bugged" room of the illicit one to be stronger than that due to the illicit one, the fall off in signal strength between the two antennae (one in the room, one on the roof, for example) is greater for the illicit transmitter than for the legal one (Fig. 1, not shown) because of the nearness of the illicit one. If the signals differ by more than a given amount, therefore, as determined by the separation of the antennae, an alarm is sounded to indicate the presence of the illicit transmitter. The antennae 24, 25, Fig. 3, may be alternately switched to a single receiver 22, or may be connected to separate receivers (7, 8, Fig. 2, not shown). Analogue stores 27, 28 are switched at 26 to the receiver in synchronism with the antennae, and their stored signals (or the outputs of the receivers 7, 8, Fig. 2) are compared at 29. A threshold circuit 30 operates the alarm, and optionally a recorder (50). The receiver frequency is stepped through a given range by a generator 34, and pulses from 35 either disable the comparator during a frequency change (Fig. 2, not shown), or clear the analogue stores (4c, Fig. 4, not shown) when a new frequency band is set up, and then enable the comparator (4d). A plurality of antennae may be set up at different risk locations, and used sequentially under control of for example a microphone which detects those locations which have conversations in progress and which therefore need protection.
