Abstract: ABSTRACT        A focusing shadow mask incorporating an electrostatic lens at each mask aperture is produced by creating an electrode comprising a set of parallel conductors on one surface of an insulator sheet and a second electrode on the other surface.      The second electrode has apertures defined either by a second set of parallel conductors that are perpendicular to the first set or by a conductive grid that includes conductors parallel to the first set and other conductors perpendicular to the first set.   Additional metal can be built up on either electrode to strengthen the combined structure.  After formation of both elec-trodes, the area of the insulating material are selectively etched away to form apertures for beams to pass through.

Abstract: ABSTRACT OF THE DISCLOSURE         Overlapping lengths of metal strap, or the like, are aligned and connected without the aid of an  overlying supple mental seal or fastener by means of an array of longitudinally spaced joints which form a one way interlocking relationship.          The joints comprise juxtaposed protuberances formed by slits in the strap ends, integral with the overlapping strap segments, which override each other as the interlocking relationship is formed.  A protuberance at an end of the array on one of the strap ends has a laterally extending projection which, upon shifting of the joined overlapping lengths of metal strap relative to each other in a direction tending to disengage the joints, wedges in the corresponding slit of the other strap to provide a stop preventing disengagement.

Abstract: ABSTRACT OF THE DISCLOSURE         A copper base alloy of superior tarnish resist-ance consisting essentially of 7.0 to 8.5% aluminum by weight and 1.5 to 2.5% nickel by weight with the balance (89-91.5 wt %) being essentially copper.         The process by which the alloy is prepared is controlled so that the alloy is primarily single phased, i.e., a face centered cubic alpha phase solid solution containing a fine dispersion of nickel aluminide compound (NiAl) and less than 2 volume percent of the brittle inter-metallic phases known as beta and gamma.  By composition control and by producing an essentially single phased microstructure, the alloys of the invention are capable of forming a stable oxide film having high tarnish resist-ance.    The alloy, upon prolonged exposure indoors to ambient air and frequent handling, develops a very thin, tight, uniform oxide film which, although visible, is still attractive and does not mask the basic warm tone of the base metal.  This film, when intact, serves to protect the underlying metal from further oxidation, and when damaged, is self-healing and re-established itself to provide a uniform protective and decorative film.

Abstract: ABSTRACT OF THE DISCLOSURE             A projectile adapted to be fired at supersonic velocity from a gun barrel includes a tubular body of sub-stantially circular cross-section having a leading inlet end and a trailing exit end and a central passageway extending therethrough.  The leading end of the body is of a shape such that the internal diameter of the central passageway decreases from the leading inlet end to a throat region.  The ratio of the cross-sectional area of the passageway in the throat region (At) to the cross-sectional area of the passageway at the leading inlet end (Ai) is sufficiently large and is so related to the projectile velocity at launch as to enable a normal shock wave to pass through the throat region to establish supersonic flow in the passageway and thus provide a relatively low aerodynamic drag after launching.  The ratio At/Ai also has a value less than 1.0 so that as the velocity of the projectile decreases to a predetermined flight Mach number, which is a function of the At/Ai ratio, the shock wave is expelled from the passageway to establish choked flow conditions in said passageway and relatively high aerodynamic drag whereby to limit the range of the projectile.                   .  .  .  .  .  .  .

Abstract: VOR PHASE MONITORING SYSTEM            ABSTRACT OF THE DISCLOSURE         A VOR monitoring system responds to the phase differen between two signals to determine the bearing of an aircraft with reference to a transmitting station.  Even harmonic dis-tortion interference in the monitored signals produces a bearing error and when the bearing error exceeds a preset limit the monitor of the present invention energizes an alarm.          The two monitored signals are identified as a 30 Hz reference and 30 Hz variable signal, each of which is doubled in frequency to 60 Hz and divided by three to produce two 20 Hz signals.  One of the 20 Hz signals is identified as a positive error signal and the second as a negative error signal.  The negative error signal is phase delayed through a programmable delay by an amount related to the bearing of an aircraft with respect to a transmitting field station.  The two error signals are then phase compared and the difference tested against a preset bearing error limit. When the phase difference between the two error signals exceeds the bearing error limit the alarm is energized.

Abstract: ABSTRACT OF THE DISCLOSURE      A push-in pressure releasing resealable closure for an aperture in a sheet metal container member is disclosed, wherein the closure is integral through a connection of metal to the remainder of the container member. The closure is designed so that it is depressible into the container by flexing about the connection when push-in force is applied to the closure, without extending the elastic limit of the connection, so that the closure is returned at least substantially to its original position to seal the can contents, upon removal of the push-in force from the closure. The closure is particularly suitable for use in containers for carbonated beverages, such as carbonated soft drinks and beer, so that the gas pressure within the container may be released without danger of substantial gushing or sporting, to permit a larger pouring opening in the container member to be opened.   The specification disclosed several embodiments of the pressure releasing closure including one in which the closure is formed partly within a pouring closure and partly outside said pouring closure whereby the pressure releasably closure is permanently opened by the opening of said pouring closure to create an air vent of liquid draining opening outside the pouring closure.           The specification also discloses methods of forming closures in which the number of forming stages is reduced. In one method, the closure piercing operation is performed at the same time as the edge of the tab is downwardly reformed. In another method, the sheet metal around the opening is also reformed in the same operation.

Abstract: Abstract of the Disclosure A rack and pinion gear assembly includes a resilient bushing which urges the rack into meshing engagement with the pinion.  An arcuate inside bearing surface of the bushing has a larger radius of curvature than the curved outside surface of the rack against which it bears.  The rack thus makes tangent contact with the bushing.  When one portion of the bushing is worn and therefore excessive play appears in the steering gear assembly, the bushing may be removed from the housing of the assembly and rotated and then reinserted into the housing to thereby provide an unworn bearing surface which slidably engages the rack.  The bushing includes a plurality of axially extending grooves through which lubricant is supplied to the gearing surfaces.  In another embodiment the aperture in the bushing through which the rack extends is composed of four arcuate segments each having the same radius of curvature, and each having a different center of curvature respectively.  This provides tangent contact between the rack and the bushing at two axially extending areas.
