Abstract: TARGET STRUCTURE FOR USE             WITH AN ALIGNMENT APPARATUS                       Abstract A target structure for use with an alignment apparatus, such as a line of sight alignment apparatus for detecting the alignment of wheels of vehicles such as automobiles, truck tractors and trailers comprises an adjustable, wheel engaging and target supporting structure mountable upon a vehicle wheel rim.  The target structure has an inner wheel mounting member with upper and lower arm members extending therefrom and engageable with the vehicle wheel rim.  An outer target mounting member is pivotally connected to the inner wheel mounting member through coaxial center portions thereof for relative rotation of the outer target mounting member relative to the inner wheel mounting member.  The outer target mounting member has spaced shaft members extended outwardly of the wheel and holding a plurality of targets at cardinal points around the wheel, the targets providing scales for determining the angular position of the vehicle wheels for conventional measurements such as caster, camber, toe and kingpin inclination.  A sighting instrument establishes a line of sight parallel to and longitudinally spaced from the vehicle and which is directed toward a target and impinges upon a discreet mark on the scale thereof.  Comparison of the points of impingement upon targets located at opposite cardinal points of the wheel establishes angular relations therebetween which correspond to alignment measurements.

Abstract: Abstract of the Disclosure Metal, fiber or plastic panels are fabricated by the attachment of planar imperforate and/or partially perforated outer sheets to a specially formed center member comprising a web or sheet having a deformed surface defining an array of adjacent triangular projections and depressions.  The center member is produced by the longi-tudinal cutting and folding of the web as it passes between two forming cylinders which mesh with one another, the cylinder peripheries carrying complementary arrays of spaced triangular-shaped tooth elements having their base lines aligned in the opposing cylinders, to shear and thereby relieve the passing web laterally so as to pro-duce intermittent parallel cuts and angular folds in the web while gathering the web longitudinally thereby to form triangular, flat-topped cells in the center member.          Instead of using two outer sheets, the formed center member can be used per se, e.g., as a packing medium, or it can be combined with only one outer sheet to form a single-face product.

Abstract: AN IGNITION ADVANCE TIMING SYSTEM     Abstract of the Disclosure An ignition advance timing system for generating the ignition  signal  or  the  injection  signal  in an engine utilizes both the advantages of an angular-based system and a time-based system.  A tooth wheel (10) operatively connected  to the crankshaft of the engine  (26)  having groups  (14)  of teeth  (16,  22,  24)  positioned thereon. Each group represents the angular  range of ignition or injection for a particular cylinder.

Abstract: LOW ENERGY ION BEAM OXIDATION PROCESS           Abstract of the Disclosure A surface reaction process for controlled oxide growth is disclosed using a directed, low energy ion beam for compound or oxide formation.  The technique is evaluated by fabricating Ni-oxide-Ni and Cr-oxide-Ni tunneling junctions, using directed oxygen ion beams with energies ranging from about 30 to 180 eV.  In one embodiment, high ion current densities are achieved at these low energies by replacing the conventional dual grid extraction system of the ion source with a single fine mesh grid. Junction resistance decreases with increasing ion energy, and oxidation time dependence shows a characteristic saturation, both consistent with a process of simultaneous oxidation and sputter etching, as in the conventional r.f. oxidation process.  In contrast with r.f. oxidized junctions, however, ion beam oxidized junctions contain less contamination by backsputtering, and the quantitative nature of ion beam techniques allows greater control over the growth process.

Abstract: METHOD OF FIRING PERFORATING GUN AND   SIMULTANEOUSLY RECORDING DOWNHOLE             PRESSURE                ABSTRACT OF THE DISCLOSURE  A casing type jet perforating gun is located downhole in a cased borehole adjacent to a hydrocarbon containing formation.          A gun firing head is connected to the uphole end of the casing gun.          A capillary tubing is wound on a large reel, and the lower end of the tubing is connected to support an apparatus for actuating the gun firing head.  The gun firing head, when actuated, detonates the shaped charges and perforates the casing.  The upper end of the capillary tubing is connected to a supply of fluid which flows at a measured pressure and flow rate,  The lower end of the tubing is open so that flow can occur from the fluid supply, through the en-tire length of the capillary tubing, and out of the lower open end of the tubing.  The gun firing device is lowered down through the tubing of the borehole by rotating the reel until the device is positioned in close proximity to the gun firing head.  The downhole pressure is measured from the surface.  The capillary tubing is next used to manipulate the gun firing device so that it contacts the gun firing head causing the charges of the gun to be detonated to thereby perforate the casing and complete the well.  A surface recorder monitors the downhole conditions during the completion of the well.  The apparatus is left downhole until the well has been cleaned up and thereafter shut-in to enable the shut-in pressure at the formation to be measured.
