Abstract: ROTARY ROCK BIT WITH MULTIPLE ROW COVERAGE           FOR VERY HARD FORMATIONS                 Abstract of the Disclosure The body of the bit includes an axis of rotation, an upper end connectable with the drill string for rotating the bit and three downwardly projecting arms.  Each of the arms includes an inwardly and downwardly inclined shaft defining an axis of cutter rotation with all of the axes intersecting at substantially a common point.  First, second and third conical cutter members are journaled on a respective one of said shafts.  Each cutter member includes a nose and a base with the base being oriented generally toward the wall of the well bore.  A plurality of outwardly projecting, circumferentially-spaced inserts are located in annular rows in each cutter member for engaging the bottom of the well bore.  At least two of the cutter members include intermediate rows of inserts disposed between the nose and base of the cutter member at approximately the same distance from the bit axis of rotation so that the inserts engage the bottom of the well bore at approximately the same distance from the bit body axis of rotation, thereby cutting overlapping tracks.     -1a-

Abstract: Abstract of the Disclosure In a metal oxide silicon memory device having an array of memory cells, A sense amplifier for detec-ting signals produced by the cells connected between complementary bit lines.   The amplifier includes a translator section that shifts the normally high bit and bit voltage levels to a lower voltage level at the control gates of signal output devices connected to out-put bus lines.   Each output bus line has only a single device impedance to ground rather than the normally required stacked or series arrangement of control elements.   This provides a low impedance to ground for one of the output bus lines while the signal vari-ation around threshold provides a relatively high impedance to ground on the other bus line, thereby providing fast response times.

Abstract: ABSTRACT OF THE DISCLOSURE         A single pressure sulfur hexafluoride circuit inter-rupter is contained in a bottle having arcing and main contacts and conductive rings fixed relative to one another, and which serve as arc runners.  Each of the rings is connected in series with a respective coil which is wound on the axis of its respective ring and which encircles the cooperating contact and conductors therefor.  A small, low capacity puffer cylinder is connected to one of the moving contacts in order to produce at least a limited amount of gas motion through the arc space between the open contacts and the fixed rings which the contacts separate.  The arcing contacts are arranged to have a blow-off path directed to cause an arc drawn between the contacts to transfer to the spaced conductive rings.  In one embodiment of the invention, only a single coil is used to produce a magnetic field for spinning the arc between the spaced rings.  The interrupter structure is useful in connection with a vacuum dielectric medium.

Abstract: ABSTRACT OF THE DISCLOSURE         A thermoplastic plate, for example one of polypropylene or nylon, fabricated so it has an open-cell structure, has a radiation transparent cover sheet applied to one face thereof.  The cover sheet has an energy absorbing coating (e.g. of carbon and nitrocellulose) in intimate contact with the plate.  A modulated laser beam is then trans-mitted through said cover sheet to selectively transfer some of the energy absorbing material to the plate according to the configuration required to define the areas of relief desired in the plate.  The cover sheet is then removed except for the portion of the energy ab-sorbing coating transferred to the plate.  The entire surface of the plate is then exposed to infra-red rays.  The portions of said surface to which energy absorbing material was transferred are elevated in temperature, by the absorbed infra-red energy, to the point that the structure beneath the transferred material collapses, thus causing those portions to sink to a plane below the plane of the other portions of the plate.  Additional infra-red heating steps may be performed to produce further collapse of said portions of the surface, as herein-after more fully explained.
