Abstract: Abstract of the Disclosure Method and apparatus for alignment of a collimator in a scintillation camera system.  First coarse alignment apparatus includes an alignment plunger coordinated with a first mating member.  A recess coordinated with a second mating member is positioned and configured to loosely receive the alignment plunger for coarse alignment.  Coarse alignment of the first apparatus establishes a vertical axis for horizontal angular rotation about which angular displacement of the members effects coarse alignment with second, coarse alignment apparatus spaced from the first apparatus.  The plunger assemblies are preferably spring loaded so that an audible click is generated when the plunger impacts the bottom of the recess to indicate coarse alignment.  The coarse alignment apparatus guides the two members into fine alignment whereupon tight fitting fine alignment apparatus coordinated with the two members is mated

Abstract: ABSTRACT      The specification discloses a double sleeve pipe coupler for coupling coaxially juxtaposed plain end steel pipe sections or pipe pile in metal-to-metal leakproof contact and at the same time providing a high strength connection under tension.  Several forms of couplers are disclosed, all essentially having two rigid metallic cylindrical sleeves of different diameter arranged coaxially one within the other with an annular space therebetween at each end into which the wall of the plain end pipe or pipe pile may be driven as by hammering or by a pile driving hammer.  The annular space between the sleeves flares radially outwardly toward the center of the coupler or expands in diameter to a larger diameter toward the center of the coupler.  Thus, as the pipe or pipe pile is hammered or driven into the coupler, the wall of the pipe or pipe pile is expanded over the inner sleeve to form a metal-to-metal seal therewith.  The outer sleeve restrains the separating movement of the pipe or pipe pile sections away from each other when placed under tension.  In the case of pipe pile, a central wall separating the annular spaces at opposite ends of the coupler provides a drive ring via which one section of expanded pipe pile may coaxially drive another section of pipe pile.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to crankcase for multi-cylinder, in line, reciprocating-piston, internal-combustion engines, in which the crankcase has at least one longitudinal lubricating-oil passage from which additional lubricating-oil passages run.  The addi-tional passages run in bearing walls located transversely of the longitudinal axis of the crankcase, to camshaft and crankshaft bearings.  The crankshaft bearings are of the suspended type and have bearing caps attached to the crankcase by means of bolts, In accordance with the invention, a longitudinal lubricating-oil passage is arranged close to the camshaft bearing and, where there is more than one lubricating-oil passage, is connected to those located on the opposite side of the crankcase by a duct, From the point of view of stress engineering, the duct is separa-ted from the dynamically stressed transverse walls.  Further, in accordance with the invention, the connecting passages to the crankshaft bearings pierce the abutment surfaces of the crank-shaft-bearing caps externally of the bearing-cap bolts and open into transverse passages, in the camshaft bearing caps, which intersect with the bearing-cap bolt-holes into which they open close to the joint in the crankshaft bearing.

Abstract: MAGNETIC HEAD DRUM CONFIGURATION HAVING A FRICTION REDUCING HELICAL STEP           ABSTRACT OF THE DISCLOSURE          A magnetic head drum includes an upper section that carries a set of magnetic heads and rotates at a preselected head speed, and a stationary lower section that is character-ized by a reduced diameter step formed along the tape wrap path thereover (e.g., a helical path for a helical scan recorder).  Because of the reduced diameter step, tape pres-sure is shifted from the lower drum section to the upper drum section which, by virtue of its rotation, produces a low fric-tion air bearing.  The reduction in diameter to produce the above-described step, moreover, results in a shoulder or ledge along the lower edge of the tape wrap path, which shoulder serves as a guide for the tape, and promotes accurate tape tracking over the drum.     The amount of reduction in diameter for the lower drum section is not chosen arbitrarily, but is preferably within a range of 1 to 6 mils.  In this range, a desirable balance is achieved between reduction in frictional drag and limiting of forces tending to distort the tape.  Moreover, it appears that a reduction greater than around 6 mils tends to result in increased tape flutter.
