摘要： A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.
摘要翻译：从金属和/或陶瓷颗粒原料压力形成棕色部分的方法包括：将由原料制成的第一原料和一种或多种另外的原料或绿色或棕色状态的插入物引入模腔或挤出机，其中不同的原料对应于零件的不同部分; 对模腔或挤出机进行加压以产生具有对应于第一和一种或多种另外的原料的多个部分的预成型件，以及脱模预成型件。从预成型件部分的内部到外部的微空隙和间隙路径允许分解或升华的主体组分的逸出基本上不会由于内部压力而产生宏观空隙。然后可以将大的棕色预制件烧结并随后进行热机械加工以产生净锻造微结构和基本上不含间隙的性质。

摘要： The present invention provides a continuous powder extrusion method for making an article having a profile including an outer shape and optionally including one or more inner hollows. One or more bulk material powders and one or more binders are provided, and the bulk material powders and the binders are mixed to form a mixture. A die is provided, the die optionally including a mandrel having one or more shapes. The mixture is extruded through the die and the optional mandrel to produce a green form. The green form is debound to produce a brown form and the brown form is sintered to produce a densified form. The densified form is optionally processed using thermal, mechanical, and/or thermomechanical processing to produce a wrought form. The densified or wrought form is optionally cut to a length and/or finished using traditional metal finishing processes.

摘要： A cathode sheath for a thermionic electron-gun cathode. The sheath is substantially in the form of a hollow cylinder and has an outer surface and an inner surface, a central axis, a closed end and an axially-opposite open end, and a side wall extending between the closed end and the open end. The sheath is a continuous bimetallic laminate having a first layer of material forming the inner surface and a second layer of electron-emission (donor) material overlying substantially the entirety of the first layer and forming the outer surface. The laminate has a preselected thickness at the closed end and has a thickness at the side wall which varies along the central axis. The outer surface of the bimetallic laminate is substantially unreactive with oxygen whereas the inner surface is more readily reactive with oxygen. When the cathode sheath is heated and exposed to an atmosphere of wet gas, the inner surface of the sheath becomes blackened (an oxide layer forms thereon) whereas the outer surface remains unaltered and substantially free from irregularities or roughness.

摘要： A tape transport which is sized to fit within an 8 inch form factor or footprint, to accommodate prevailing mini/micro computer applications, and including operative components which are capable of automatically receiving IBM Corporation's 3480-type tape cartridge and the web of tape which it contains for appropriate introduction to the transport for presentation to a high performance magnetic recording head. This permits a use of the 3480 tape cartridge in a transport apparatus which is capable of fitting within an 8 inch form factor or footprint, and which is therfore acceptable for use in connection with many mini/micro computer applications, yet which is capable of providing high performance (parallel track, high transfer rate) storage and retrieval due to its compatability (and interchangeability) with the format used by the IBM Corporation in connection with its 3480 tape cartridge.

摘要： A multilayer composite tubular structure for use as a stent in surgical procedures has an outer layer of biocompatible material, a middle layer of radiopaque material, and an inner layer of biocompatible material. The layers are metallurgically bonded, to form a composite stent which is ductile and permits large deformation without delamination between the biocompatible and radiopaque layers. The composite structure formed is visible on a fluoroscope, yet does not obstruct the details of the stent itself, or of the anatomical features surrounding the stent.A process of forming a multilayer composite tubular structure is also disclosed. A tube formed from radiopaque material is coaxially surrounded by a tube of biocompatible material. The tubes are simultaneously reduced, such as by tube drawing, swaging, or deep drawing, until a composite structure of a desirable diameter and wall thickness is formed. The tubes are then heat treated to cause diffusion bonding of the biocompatible and radiopaque layers.
