Title: Commutation overlap calculator for static electrical converters
IPC: G01R31/26
Filed: 1972-07-07
Abstract: 1386995 Controlling converters ALLMANNA SVENSKA ELEKTRISKA AB 7 July 1972 [8 July 1971] 31933/72 Heading H2F A method of calculating and indicating the commutation time for a pair of commutating rectifiers in a converter 1 comprises storing the load current value in an integrating memory circuit 20, 21, to the input of which the commutation voltage is connected at the start of the commutation, the integral of the commutation value being continuously subtracted during the commutation from the current value and a signal being emitted when the difference is equal to a prescribed value. As shown in Fig. 1, triggering pulses for the converter 1 are supplied by a device 6 via a gate 8 to a distributer 7. The current on the D.C. side is monitored by a transductor 11, the output of which is adjusted at 15 (Fig. 2) and amplified at 16. Up to the time of each commutation, gate 22 is conductive so that the value of current is stored by integrator 20, 21. At the beginning of each commutation period, a control pulse 10 sets a bi-stable circuit 28 so that gate 22 is blocked and gate 23 made conductive, feeding the integrator 20, 21 with the commutation voltage derived from one of the phases of transformer 13. The outputs of integrator 20, 21 and amplifier 16 are subtracted in a summing junction 24 which operates a discriminator 26 when the difference is zero. The circuit is adjusted so that the time to reach zero is equal to the commutation time of the converter 17 At the end of the commutation period. bi-stable 28 is reset so that a pulse is emitted at 9 to enable gate 8 to pass the next triggering pulse to the converter 1. A delay 29 compensates for the delay in the firing circuit. A monostable 30 and OR gate 31 extend the duration of the pulse at 9 to allow for the recovery time of the rectifiers. The signal from gate 31 is fed to an AND gate 32, enabled by a discriminator 33 when the commutation voltage passes through zero so that an output at 35 can indicate a commutation fault. Modifications.-In Fig. 4 (not shown) the summing junction 24 is omitted and a rate of change of current component included at the input to amplifier 16.

A tubing anchor comprises slips 13 engaged with casing 16 by movement of a piston 10. The anchor is lowered into the casing on tubing 9, the piston being held at the top of its cylinder by fingers 4 which engage a ring 1 placed beneath a head 3 on the piston rod 2, and a slip expander 14 depending from the piston being held inoperative. When the anchor is positioned to be fixed the tubing is filled with fluid causing the piston to decend to the bottom of its cylinder, the fingers to engage the sides of the head, the ring to fall onto the piston, and the expander to engage the slips with the casing. The tubing is lowered slightly to increase the pressure of the slips on the casing. The anchor is disengaged by lifting the tubing, the fingers engaging beneath the head to move the expander from the slips, and the slips being finally freed from the casing by being engaged by projection 19 on the anchor housing.

Abstract: 371,423. Valve accessories. FLEISCHER, B. O., 52, Aubert Park, Highbury, London. Oct. 25, 1930, No. 32130. [Class 135.] Leakage preventing and discharging.-A reversing valve for a regenerative furnace is arranged so that the pressure in a zone separating the two fluid streams controlled by the valve is maintained equal to the pressure of one of the fluids to prevent leakage between the two fluid streams. In the form shown in the Figure the valve comprises a pair of plates F spaced apart to provide a chamber H and mounted on a rotatable spindle I. The valve co-operates with a pair of seats E arranged at right-angles to connect the air or gas conduit A to one of the flues B, C while the other flue is connected to the chimney. The chamber H is coupled through the hollow spindle I either to the inlet of a fan discharging into the air conduit or to the outlet of a fan drawing flue gases from the chimney flue. The speed of the fan or a throttle in the fan conduit is operated to maintain the pressure in the chamber H equal to the pressure on one side of the valve. The plates F may be made concave instead of flat and the chamber H may be made in the edge of the valve. According to the Provisional Specification the outlet from the fan may be controlled by a valve interconnected with the reversing valve and arranged to connect the outlet to whichever flue is for the time being in use as an air flue. Further a valve may be associated with the hollow spindle to close the fan inlet during the time the reversing valve is moved from one position to the other. The arrangement may be used on valves other than reversing valves intended to separate two zones of air, gas, or liquid at different pressures. Specification 268,816, [Class 135, Valves &c.], is referred to.

De-ionized water is fed to sleeve 4 from container 6 and trough 3. Also described is an apparatus in which the film-supporting porous sleeve is surrounded by the infra-red emitter, and the cooling coil is within the sleeve. The feed container is closed, and is associated with a pipe for bubbling nitrogen through the preheated feed water in order to remove dissolved carbon dioxide. The sleeve may be made of porous carbon or silica, or fritted metal.

Tools.-A tool for polishing glass comprises a core coated on the working-surface with a polishing-layer comprising a mixture of polishing-powder and powdered resin or resinlike substance, which is heated to the fusing temperature of the resin or a temperature below fusing point. As applied to a flat or slightly curved tool, a core a has applied thereto a mixture of the powder and resin-like substance, for example rouge and shellac in equal quantities, which is compressed by a plate c and a clamp d and then heated for about one hour at a temperature of about 100‹.
