Abstract: POWER DRIVEN SCREW DRIVER WITH    A SCREW HOLDING NOSEPIECE     Abstract of the Disclosure A power driven screw driving tool having a screw holding nosepiece detachably mounted to its end, the nosepiece having slidable sleeve members cooperable with ball elements to obtain an initial locked condition of a screw entered into the nosepiece for positioning the screw relative to the work, and being cooperable with one another to obtain a released condition to per-mit the screw to be finally driven out of the tool into the work.  A first embodiment describes the nosepiece as adapted for use with a tool in which the spindle and driving bit are restrained against axial movement rela-tive to the housing.  A variation of the first embodiment describes the nosepiece as having a screw back-up sleeve as being fixed to an inner sleeve, rather than relatively slidable as in the first embodiment.  And a further em-bodiment discloses a modified form of the sleeves and back-up element in a nosepiece associated with a clutch engageable spindle and bit, the back-up element in this embodiment being adjustable according to variations in the heads of screws to be accommodated.  The arrangement of the components of the tool is such that while the tool -i-is held in one hand, it requires a simple continuous operation of pressing a screw into the nosepiece with the other hand until a gripped condition of the screw is obtained therein.     -ii-

Abstract: ABSTRACT     A process of forming powdered metal into finished or near-finished, high-strength, structural parts of complex configurations wherein a metal powder preform is heated to a temperature of approximately 2100°F and formed at relatively low pressures in the range of approximately 19 to 39 tons per square inch over a short contact time interval in a preheated forming die composed of a high temperature, high strength superalloy to produce a metal part having a density of 99% or greater of theoretical density.  The preform is formed from a prealloyed metal powder blended with graphite and a lubricant, compacted to a density in the range of 70 to 80% of theoretical density, and heat treated for oxide reduction and solutioning of the graphite therein.  The preform must be rapidly transferred from the heat treatment operation to the preheated forming die to minimize reoxidation and cooling of the preform.

Abstract: PRESSURE CONTROL VALVE            Abstract of the Disclosure A differential pressure control valve is solenoid operated on a controlled duty cycle to alternately open and close a pair of inlets to establish a desired outlet pressure.  The valve member acts as a solenoid armature. It is of sandwich construction with a magnetically soft center section and a thin, wear-resistant, nonmagnetic coating on one or both sides.  The nonmagnetic coatings or layers are disclosed as being made of a nonmagnetic stainless steel, while the center section is disclosed as being made of a low carbon steel having a low magnetic remanence or residual magnetization.  Valve life is increased due to the wear resistance of the stainless steel, and the nonmagnetic characteristic of the stainless steel layer adjacent the field plate avoids erratic retention of the valve member against the solenoid core and field plate.  The arrangement is such that the magnetic forces across the valve member during solenoid energization act in parallel.

Abstract: OPTICAL ARTICLES PREPARED FROM HYDRATED GLASSES       Abstract of the Disclosure A glass article having an optical quality surface smoothness can be formed by molding a "silanol" glass mate-rial against a die having a molding surface which is a mirror of that required for the glass article, thereby obviating glass grinding and polishing steps.  The article is prepared by first forming an anhydrous base glass com-prising, in mole percent on the oxide basis, about 72 to 82%          SiO2, 10 to 17% Na2O and/or K2O, and 5 to 15% of an oxide or oxides selected from ZnO and PbO.  The base glass may include up to 5% A12O3 and up to 3% of B2O3, BaO and/or MgO.  The anhydrous base glass is then hydrated to include a water content ranging from 0.5 to 10% by weight to form a "silanol" glass.  That glass is then molded against the die surface at a temperature ranging from about 250°C. to 500°C. and a pressure ranging from about 4,000 to 20,000 psi for a period of time sufficient to replicate the surface smooth-ness of the die on the glass and, depending on the molding process, yield a glass article containing about 0.5 to 10% by weight of "tightly" bound total water.            Related Application:  U.S. Patent No. 4,026,692, in the name of R. F. Bartholomew et al, entitled "Optical Articles From Acid Hydrated Glasses" and assigned to the present assignee.

Abstract: ABSTRACT OF THE DISCLOSURE Bag printing apparatus of known type cannot be used with a bagging machine of straight line configuration, that is, one in which the stack of bags is positioned in the line of travel of the products to be packaged, immediately below their path, and the packaged product travels on in the same direction.  The novel apparatus disclosed can be used in conjunction with such machines as well as with other types of machines, including hand bagging machines.  The disclosed apparatus is especially useful for print-ing on the generally horizontal upper surface of the upper uninflated bag of a stack of generally flat, uninflated bags, while an inflated bag is posit-ioned thereabove at the top of the stack for subsequently receiving a prod-uct therein.  It includes a print head having a print face, preferably hor-izontally positioned, and a print head carrier for moving the print head from an inoperative position to a remote printing position along a curved path, its motion being initially away from the inoperative position, preferably in a generally horizontal direction, and finally toward the printing position in a generally perpendicular, preferably vertical, direction to the upper sur-face of the upper, uninflated bag for printing its upper surface.  There may be included a bag deflector for deflecting the inflated bag from the printing position to expose at least a portion of the upper surface of the upper, un-inflated bag for printing thereon.  The deflector may consist of an air jet mounted adjacent the print head for movement therewith to deflect the in-flated bag in advance of print head movement.

Abstract: ABSTRACT OF THE DISCLOSURE           In a continuous casting system where molten copper is cast into a bar and then rolled into a rod, the copper rod is immediately hot-coiled before being subjected to any quenching or cooling operation.  The hot-coiling of the rod is carried out at a temperature of from 700°F. to 1200°F. and preferably within a range of from 950°F. to 1150°F., so that the rod is hot-coiled at a high enough temperature to permit sufficient thermal vacancy diffusion to occur within the rod material, and thereafter gradually cooled to room temperature to thereby impart certain im-proved mechanical properties to the resultant rod product. A copper or copper alloy rod which is processed in this fashion has a lower yield tensile strength, lower ultimate tensile strength, lower recrystallization temperature, lower hardness and is much more ductile and hence easier to draw into wire than a corresponding rod which is quenched or cooled prior to coiling.
