Patent EP-0107003-A1 (EP)
Inventor: STEIGERWALD ROBERT LOUIS
IPC: H02M3/28
Filed: 1983-09-12
Abstract: A dc-dc converter employs a parallel resonant circuit (23, 25) which is driven by square waves of current. By adjusting the frequency below the resonant point, the voltage on the resonant components can be stepped up. Switching losses in the inverter devices (6) are low since the inverter feeds a lagging load allowing lossless snubber operation which allows the use of lossless snubbers (15,17, 19,21).

Abstract: Granular poly(arylene sulfide) is recovered from a slurry comprising granular poly(arylene sulfide), polar organic solvent, alkali metal halide, poly(arylene sulfide) oligomers, untreated reactants in the water by heating the slurry under conditions to evaporate polar organic solvent, water and volatile impurities at a temperature below the normal boiling point of the polar organic solvent to produce a dry mixture containing poly(arylene sulfide), poly(arylene sulfide) oligomers and alkali metal halide which is then reslurried with water to produce a reslurried mixture containing aqueous alkali metal halide solution and dispersed poly(arylene sulfide) oligomers with the reslurried mixture being filtered through a coarse screen to recover granular poly(arylene sulfide) thereon and pass a filtrate containing poly(arylene sulfide) oligomers and aqueous alkali metal halide solution therethrough. The filtrate can be further treated by filtering through a filter aid coated vacuum filter to recover poly(arylene sulfide) oligomers thereon and pass an aqueous alkali metal halide solution therethrough as filtrate.

Abstract: @ A spot weld control senses differences in welding current required to produce an optimum weld by determining the time rate of change of resistance during the increasing resistance portion of the weld cycle. The weld control can reduce the welding current if the time rate of resistance change exceeds a maximum value and increase the current if the resistance change is less than a minimum value. The weld current may be terminated when a decrease in resistance from the peak resistance value has reached a predetermined percentage of the peak resistance value or terminated after a predetermined number of current cycles.

Abstract: An improved process for the catalytic dehydrochlorination of 3,4-dichlorobutene-1 with aqueous alkali, wherein the effluent from the dehydrochlorination reactor is separated into phases, and the organic phase is steam-stripped at low temperature (below about 80°C) to recover chloroprene product, while the steam stripper heels are returned to the dehydrochlorination reactor. A small portion of the heels is purged prior to being recycled. Most of the catalyst is recovered and returned to the reaction, but a small amount of make-up catalyst is added. Chloroprene made in this process is a valuable monomer which finds use in the manufacture of a broad line of synthetic elastomers of considerable industrial interest.

The resilient stopper is positioned inside the bottom of the screw cap so that the bottom surface of its resilient projecting edge comes to rest against the offset above the thread when not screwed on and its lower section is dimensioned so that it can be introduced tight into the neck of the flask. The support has two surface that can be coated with a solid culture medium on opposite sides, is fastened to the bottom of the resilient stopper, and extends in use only over part of the height of the flask, and the top of the screw cap is designed so that in assembled state it forces the resilient projecting edge of the stopper tightly against the upper edge of the neck of the flask.

Abstract: 57 For belt conveyors in which the loaded part of the belt is supported by a gas layer in a through, the energy needed to drive the belt is lower if the belt is more fully out of contact with the trough. But much energy is needed to compress the gas carrying the belt. The invention proposes to provide means to measure the power for these two purposes and to alter the gas flow into the trough so that the total power requirement is at a minimum. The latter may be performed in steps and as soon as a step appears to result in an increase of power required, this step may be undone. Drives of the belt (1) and of a compressor (6) by electric motors (5, 8) make measurement of electric power supplied thereto preferable. A control member (14) receives signals of power measurements and issues signals to change the power for drive of the compressor. Instead of separate measurements added by the control member (14) the latter may be fed with a measurement of the total power supplied for both purposes. For long conveyor belts there may be more than one compressor and more than one electric motor for moving the belt, in which case, together with the control of the compressors, one or more of such drive motors may be switched on or off to keep the operating motors at high efficiency.
