Abstract: A switching drive circuit includes a first transistor which supplies a load with a drive current for a forward direction in response to a first pulse signal, and a second transistor which supplies the load with a drive current for a reverse direction in response to a second pulse signal. The drive circuit drives the load by switching a current through the load on and off in response to the first and second pulse signals. The drive circuit further includes a first switching means for shorting the first transistor between its base and emitter at the time of disappearance of the first pulse signal. A second switching means shorts the second transistor between its base and emitter at the time of disappearance of the second pulse signal.

Abstract: In scales having a weighing plate (32) that is guided vertically by means of a lying parallelogram system (8,18,22,28) it has been common standard that this system has to be 'stiff', such that the weighing plate is downwardly displaced in parallel even if it is loaded only at a peripheral, local area. In connection with the invention it has been realized that this arrangement can give rise to excessive and demolishing influence on an associated weighing cell (36,52) in case of impact-like loadings of the weighing plate, and on this background it is proposed that the parallelogram system be designed less stiff and more resilient than conventionally. In practice this design implies that a corner of the weighing plate (32) can be locally depressed against an underlying depression stop (6) without the other corners of the weighing plate thereby being depressed against respective, associated depression stops (6).

Abstract: This invention relates to a method for eliminating the grayish discoloration which commonly develops when lead-free and cadmium-free glass frits are applied to substrates utilizing an organic medium and thereafter fired to fuse the frit particles into a glaze. The grayish discoloration contains a carbonaceous residue from the organic medium. The method comprises the four general steps:
     (1) adsorbing a coating of a strongly oxidizing metal ion species onto the surface of the frit particles;   (2) mixing the coated frit particles with an organic medium;   (3) applying that mixture to a substrate; and   (4) firing the mixture to eliminate the organic medium and to oxidize the carbonaceous residue while fusing the frit particles into a glaze.

Abstract: The present invention relates to a sizing agent which exerts excellent sizing efficiency even under severe conditions, namely, at an elevated temperature in the paper-making step, or at high conditions with a limited aluminum sulfate addition. 
     The sizing agent for paper of the present invention is derived from i) dehydration condensation of an alkenylsuccinic anhydride and an organic carboxylic acid with a polyalkylene polyamine and ii) saponification of the remaining carboxyl groups with alkali following the dehydration condensation. More particularly, the present invention relates to a water-soluble sizing agent which is obtained by mixing an alkenylsuccinic anhydride with 1 to 20 times by molar equivalent, based on said alkenylsuccinic anhydride, as much as an organic carboxylic acid, adding 0.1 to 2.0 times by molar equivalent, based on said alkenylsuccinic anhydride, as much as a polyalkylene polyamine thereto so as to perform dehydration condensation. An then, to make the reacted material soluble to water, the remaining carboxyl groups are saponified with an alkali in an amount almost corresponding to the saponification equivalent.
