Abstract: ABSTRACT    The present invention provides washing compositions in which all or part of the detergent builder salt is provided by a mixture of zeolites 13X and 4A.  Preferably the weight ratio of 13X to 4A is in the range of 50:50 to 85:15 and especially from 65:35 to 85;15.  Especially in the preferred ranges of weight ratios the mixtures are generally more effective at total hardness removal from the wash water than would be expected from the hardness removing capabilities of the zeolites 13X and 4A by themselves, leading to improved washing performance of the composition.  In some particularly desirable embodiments part of the builder salt comprises STPP, and in others a minor part of the builder salt comprises a glassy phosphate, preferably together with an ethyleneamine (methylenephosphonic acid) complexing builder salt.   The compositions of the present invention are suitable for cleansing,in particular,fabrics or hard surfaces.

Abstract: 47,891 SEMICONDUCTOR SWITCHING DEVICE                  ABSTRACT OF THE DISCLOSURE          The stabilization of electrical switching para-meters in a semiconductor switching device is achieved by selectively doping a portion of semiconductor material with a heavy metal to form stable charge recombination centers and irradiating the remaining semiconductor material to form radiation induced charge recombination centers.  In an important embodiment of the invention, a center-fired four region semiconductor switching device consisting of silicon semiconductor material is prepared by gold doping the silicon in the area around the center firing gate con-tact where initial conduction of current is concentrated.          The remainder of the active area of the device, but not the gold doped region, is irradiated to provide recombi-nation centers for fast switching without the adverse effect on blocking leakage current that is attributable to indis-criminate gold doping.  The gold provides recombination centers in the initial conductive area which are not subject to annealing as are the recombination centers provided by irradiation.

Abstract: ABSTRACT OF THE DISCLOSURE              A contactor comprises a contact system arranged  in a housing with a magnet system activating the contact system. The housing, at the end thereof remote from the side of the housing at which the housing is mounted in a switch box, is closed off by a cover.  The contact system comprises contact bars with contact terminal screws and stationary contact pieces, and jointly activatable bridging members having movable contact pieces and operating as normally closed and/or normally open switches.  The contact bars with their contact terminal screws are arranged displaced relative to one another in planes having differing spacings from the end of the housing at which the housing is mounted on a switch box, in such a manner that each contact terminal screw is freely accessible, even after all wiring has been connected on.  This makes possible direct access to connections at the terminal screws of the more deep-lying planes, and makes it possible to wire on in sequences other than beginning with the plane closest to the mounting plane.

Abstract: ABSTRACT OF THE DISCLOSURE                   This invention relates to apparatus for electron beam lithography capable of the automatic focusing of a shaped electron beam. An electron beam is uniformly projected onto a reference aperture plate having an opening of any desired shape, and the thus obtained beam in the shape of the opening is reduced and projected onto a specimen to perform a process-ing operation in a microscopic pattern on the specimen. An electron beam-deflecting device periodically changes the direction of the beam, such device being disposed between an electron gun emitting the beam and the reference aperture plate. Deviation of the position of the final-image beam corresponding to the angle of deflection of the beam due to the beam-deflecting device is detected, and the focal length of a final-stage electron lens correspondingly adjusted to minimize the positional deviation. The result is effective focusing of the projected beam.

Abstract: ABSTRACT         A self-developing camera with automatic focusing has a charge control system which charges the flash tube capacitor while other camera functions are inactive, and which disables capacitor charging during automatic focusing and during the film-related operations of exposure, transport, and processor-spreading.  An enabling stage allows flash-illuminated exposure only when the storage capacitor is prop-erly charged.  The charge control system thus schedules high current operations to occur one at a time so that a single battery can power all camera operations.  Further, it inhibits exposure under conditions of inadequate flash readiness. The control system affords the user of an SLR camera with a view-ing interval between automatic focusing and exposure.

Abstract: ABSTRACT OF THE DISCLOSURE :       The invention is concerned with a waelz process of volatilizing zinc and lead from iron-containing and oxide-containing material in an inclined rotary kiln, which is charged at its upper end with the material together with solid carbonaceous reducing agent having a high content of volatile combustible constituents, wherein the reduction and volatili-zation are effected below the softening point of the charge, metallic iron-containing material is discharged from the lower end of the rotary kiln, combustion air is sucked into the lower end of the rotary kiln, and the exhaust gases are sucked from the upper end.  The process of the invention is characterized in that oxygen-containing gases are blown at controlled rates through tubular air nozzles into the charge disposed over tubular air nozzles in that region of the heating-up zone wich begins where ignitable particles of the solid reducing agent begin to occur and which therminates at up to 50 % of the length of the kiln.  This process results in a higher through put rate and permits the use of inexpensive reducing agents.
