Abstract: ABSTRACT OF TIDE DISCLOSURE A novel process is provided for providing a case-hardened, cor-rosion-resistant steel article.  The process comprises: applying a coating of nickel and/or cobalt to the surface of the article and then subjecting said coated article to carburization by heating said coated article to and maintaining it at an austenitic temperature under carburizing conditions for a time sufficient to effect carbon diffusion into the surface of the steel article thus producing a carburized zone underneath the metal coating. The corrosion resistance of the steel may be further enhanced by applying a thin layer of a final metal coat selected from the group consisting of Cr, Sn, Pb, Zn, Cu and Cd.  The article so formed not only has improved re-sistance to corrosion, but also has improved physical properties.

Abstract: A B S T R A C T           It is known to solder electronic components to printed circuit boards but this makes subsequent component removal difficult.  It is also known to use spring-loaded retaining sockets but these tend to form inferior electrical connections.  The present invention provides a method of making connections which comprises bringing a plurality of reversibly-temperature-actuatable devices attached to a carrier into contact with the substrate, fixing the contact devices to the substrate, raising or lowering the temper-ature of the contact devices to cause them to release the carrier and then bringing a plurality of members into contact with the plurality of contact devices and raising or lowering the temperature of the contact devices to cause them to grip the members.  The "reversibly-temperature-actuatable contact device" is one which will adopt a first configuration at a first temperature (released position) and a second configuration at a second temperature (gripping position).

Abstract: TURBINE VANE COOLING                   ABSTRACT OF THE INVENTION      A method and apparatus for providing high pressure cooling air to the turbine vanes of a gas turbine engine is disclosed.          A centrifugal compressor stage is interposed in the flow path of cooling air to the turbine vanes.  The centrifugal compres-sor stage raises the pressure of the cooling air to a value substantially greater than the pressure of the combustion gases entering the turbine.  The availability of high pressure cooling air allows the incorporation of improved cooling systems in the turbine vanes.  Increasingly effective cooling systems are necessary to the continued development of low pressure drop combustion chambers which discharge high temper-ature gases to the inlet of the turbine.

Abstract: ABSTRACT OF THE DISCLOSURE       An ingredient for enhancing the texture and organoleptic properties of tapioca-style pudding.   Granular starch is pre-extruded under controlled conditions to obtain partially gelatinized spheroidal starch particles for use in tapioca-style  puddings.   The spheroidal starch particles (or "pearls") retain their spheroidal shape in the finished pudding, thereby providing excellent texture, appearance and mouthfeel to the pudding.  The starch pearls, after cooking, consistently provide the highly desired translucent appearance expected in home cooked, tapioca-style puddings.   The extrusion process is cooled by water at a temperature below 100°F. at an extrusion rate which only partially gelatinizes the starch.  The granular starch is supplied to the extruder at 25-50% moisture, and the extrudates are cut into particles suitable for a particular use by a cutting means as the extrudates emerge from the extruder die orifices.  The particles are then dried, as by oven drying, to less than about 12% moisture, dry solids basis. The drying temperature should be kept low enough to avoid additional gelatinization of the partially gelatinized starch particles. Particularly suitable starch particles for use in automated canning process have been found to be gelatinized to a level of about 45-70% by weight, dry solids basis.

Abstract: FET DEVICE WITH REDUCED OVERLAP CAPACITANCE AND METHOD OF MANUFACTURE          ABSTRACT         A metal gate transistor is fabricated to have reduced gate overlap of source/drain regions and increased oxide thickness over the diffused regions whereby parasitic capacitance is reduced and switching speed is increased.          The method comprises the steps of (1) selecting an appro-priate insulating thickness over a semiconductor substrate, (2) forming source/drain diffused regions in the substrate through openings in the insulating layer at appropriate diffusion temperatures, (3) selecting an appropriate drive-in and regrowth temperature whereby the insulating layer thickness over the diffused region is greater than that over the non-diffused region and out diffusion of the diffused regions is minimized, (4) etching the region between the source/drain to form a gate area and (5) growing a prescribed gate insulation thickness for a metal gate whereby the gate insulation overlap of the diffused region and the thickness of the gate insulation overlap of the diffused region reduce the parasitic capacitance and increase the switching speed of the resulting metal gate transistor relative to prior art tran-sistors.
