摘要： The preferred embodiments of the invention is an optical system for a flow cytometer including a flow channel with an interrogation zone, and an illumination source that impinges the flow channel in the interrogation zone from a particular direction. The optical system preferably includes a lens system and a detection system. The lens system preferably includes multiple lens surfaces arranged around the flow channel and adapted to collect and collimate light from the interrogation zone. The detection system preferably includes multiple detectors adapted to detect light from the lens system. Each detector preferably includes a local filter that independently filters for specific wavelengths. Thus, the user may easily swap the filters in any order to achieve the same detection parameters.

摘要： The invention relates to a process for the removal of oxides and/or oxygen which are formed on the surface of the casting during the investment casting process to levels that are comparable to those found within the bulk of the metal casting thus reducing the inherent hardness of the surfaces of the casting. More specifically, the invention relates to a process for removing oxide layers from titanium casting using an alkaline earth deoxidizing agent.

摘要： A fluidized bed condenser for use in condensing zirconium tetrachloride or hafnium tetrachloride vapor into solid zirconium tetrachloride or hafnium tetrachloride includes a scraper assembly. The scraper assembly includes at least one scraper arm located adjacent an inlet through which fluid zirconium tetrachloride or hafnium tetrachloride enters the condenser vessel. A cleanout rod is also mounted on the vessel to clean out the inlet, and the scraper includes a cleanout assembly for preventing build up of solid material in a solid outlet area defined in the vessel.

摘要： A process for the deoxidation of a refractory metal containing minor concentrations of oxygen is disclosed. In this process the refractory metal is contacted with a metallic deoxidant in a dry, inert atmosphere. The metallic deoxidant and the refractory metal are heated to at least liquefy the metallic deoxidant and at least partially deoxidize the refractory metal. The refractory metal is thereafter cooled and contaminants on its surface are removed.

摘要： Process for deoxidizing refractory metals such as titanium which contain less than about one percent oxygen. The process described includes heating a liquid metal deoxidant contained in a liquid metal carrier to treat the oxidized metal. After removing the carrier and cooling, the metal is leached to result in a treated metal with lower residual oxygen. In a preferred embodiment, titanium alloy powders are deoxidized with calcium in a sodium carrier.
