Abstract: ABSTRACT OF THE DISCLOSURE           The present invention pertains to a light acti-vated thyristor which increases the current density of light-generated carriers by means of a low resistance path from an area of carrier generation in a base zone of a first conductivity type into a portion of an adjacent emit-ter zone of a second conductivity type.  In one embodiment the low resistance path takes the form of an annular gate electrode affixed to the base zone and having a projection bordering the base-emitter PN junction.  In another embodi-ment the low resistance path takes the form of a ballast segment disposed in the base zone, the ballast segment hav-ing an opening for funnelling the carriers to the base-emitter PN junction.

Abstract: A PROCESS FOR THE PRODUCTION OF S-ALKYL PHOSPHORO DIHALOGENIDODITHIOTE                 Abstract of the Disclosure S-alkyl phosphoro dihalogenidodithioate  is prepared by the reaction of alkyl mercaptan with a phosphorous trihalogenide (PX3) and elemental sulfur in the presence of a sulfurization catalyst.  The alkyl mercaptan may be reacted with the phosphorous trihalogenide either in a separate vessel or in the same vessel as the subsequent sulfurization of these reaction products. Sufficient sulfur is used to sulfurize substantially all phos-phorous atoms present to a penta-valent state.  If a sufficient excess of phosphorous trihalogenide is not used in the initial reaction either additional phosphoroustrihalogenide or PSX3 is added so that at the end of sulfurization there is at least about one mole of PSX3 present for each mole of S,S-dialkyl phosphorohalogenido trithioate and two moles for each mole of S,S,S-trialkyl phosphorotetrathioate present.  The PSX3 and dialkyl and trialkyl compounds are held at sufficient temperature for a sufficient time to convert them substantially to S-alkyl phosphorodihalogenidodithioate.  A period of at least about 1 hour at not less than about 150°C is preferred.  The PSX3 and product (S-alkyl phosphorodihalogenidodithioate) may be removed as distillation overheads and the  residue left as a heel for subsequent cycles.

Abstract: CAPILLARY FLOW METHOD AND APPARATUS FOR DETERMINATION OF CELL OSMOTIC FRAGILITY           ABSTRACT OF THE DISCLOSURE    A method and apparatus for the determination of blood cell osmotic fragility, wherein a solution of salt, such as sodium chloride, with an osmotic gradient decreasing with time is passed through a coiled capillary tube, positioned with its axis vertical so that the flow through the turns of the tube is substantially horizontal, and the flow follows Poiseuille's parabolic flow pat-tern.  The blood sample is inserted  in the coiled tube and, because of the flow pattern, the sale solution travels through the capil-lary tube much faster than the erythrocytes, so that the erythro-cytes are exposed to gradually decreasing osmolarity for hemolysis.          Optical monitoring is carried out as the hemoglobin is rapidly re-moved from the flowing stream.  Optical density is recorded against time, employing a 547 nm monitoring beam, thus providing a hemolysis curve.

Abstract: COPY PRODUCTION MACHINE HAVING A DUPLEX COPY MODE      ABSTRACT A copy production machine operates either in a simplex ode (each copy has an image only on one side) or in a duplex lode (copies have images on both sides).  In the duplex mode, an interim storage unit stores partially completed copies (only one side of the duplex copies have an image).  A second copy run completes the duplexed copy production.  During power on sequencing, circuits sense for an intermediate copy production state and automatically makes machine selections for a copy production mode in accordance with the sensed intermediate state.  In one early embodiment the intermediate state was copies residing in the interim storage unit and the selected copy production mode was the production of side 2 in a duplex node.  An electronic nonvolatile memory may also store inter-mediate state indications for use during power on sequencing.
