Abstract: Abstract of the Disclosure A proportional processing technique having a wide instantaneous  dynamic range and providing a significant increase in instantaneous dynamic range over presently known proportional processing methods.  These improvements are made possible by the use in accordance with this invention of a logarithmic amplifier in each channel of a pair of channels relatable to the same sensing plane.  Each logarithmic amplifier is preferably arranged to operate substantially at the midpoint of its operating characteristic, and the pair of channels may be orthogonally related to another pair of channels, such that suitable guidance commands can be derived and furnished for example to a missile.  Each logarithmic amplifier produces signal outputs of nanosecond duration which are converted into signals of at least sufficient duration to provide sufficient time for comparison of the channel output signals thereby produced.  The channel output signals are compared to produce a steering command output that has a polarity indicative of the channel having the higher output signal level, and has a slope representing volts versus target bearing that is independent of the input signal level thereby inherently accomplishing normalization.  The steering command output is limited to a preselected voltage level below a non-linear region of the output.

Abstract: ABSTRACT           Hydrocarbonaceous materials such as petroleum residuums, coal, lignite or the like are introduced into a molten salt bath maintained in a reaction zone at elevated temperature and pressure.  Hydrogen also is introduced into the reaction zone in  an amount sufficient to provide a pressure in the reaction zone within the range of from about 30 to 400 atmospheres.  The hydrocarbonaceous material is reacted for a time sufficient to produce cracked products including a major amount of liquid and a minor amount of gaseous and solid products of enriched hydrogen content.  The molten salt bath comprises at least one alkali metal hydroxide which preferably is sodium hydroxide. Substantially all of the sulfur and ash constituents of the hydrocarbonaceous material are retained in the molten salt. When the hydrocarbonaceous material is a normally solid material such as coal, it advantageously is crushed and slurried in an organic hydrogen donor solvent prior to its introduction into the molten salt bath.

Abstract: EXPLOSIVES PACKAGE                     ABSTRACT OF THE DISCLOSURE           An explosives package is disclosed comprising a plastic tubular container having male and female ends ada-pted to be coupled with like containers to form a column, and primer and blasting explosives contained therein.  The container is open at both ends and has an internal circum-ferential ring seat.  The ring seat and open end of the con-tainer enables a cast primer composition to be poured through the open end onto a piston which is in fluid-tight relationship with the ring seat. A capwell thimble is in-serted into and retained in the side of the male end of the container so that the closed end of the capwell is situated within the cast primer composition.  The male end of the container in the area of the capwell is adapted to provide protection for the legwires of a blasting cap inserted in the capwell from being nipped or damaged by other, coupled, containers or borehole walls; the protection is preferably provided by a depression around the capwell entrance and a longitudinal channel leading therefrom, on the exterior of the container.  Subsequent to pouring the cast primer comp-osition into the container and allowing the composition to solidify, the piston is removed from the container and a blasting explosive e.g. a slurry explosive in a "chub" package is inserted into the container and is retained there-in by a closure disc.  The primer and blasting explosive are in abutting relationship within the container.           The explosives package is particularly useful in seismic prospecting applications.

The machine described is supplied with spools of tape, and with buckles and rings, and performs all the operations needed to produce the strap including sewing of the buckles and rings in place, and the threading and buckling operations, as well as cutting off suitable lengths of the tapes, The means for uniting the first and second tapes comprises a first clamping device for holding the buckle end of the first tape with the buckle disposed substantially perpendicular to the tape, and a second clamping device having a narrow projecting end for holding the free end of the first tape and being suitably dimensioned for inserting this free end through the ring of the second tape, and subsequently into a slot of the buckle.  These clamping devices are moved between an initial position in which the free end of the first tape is held horizontally for receiving the ring, and a final position in which the free end has been rotated through 180° and can then be inserted into a slot of the buckle.  Buckling means are provided for completing the buckling of the first tape through the second slot of the buckle.

Abstract: COLLAPSIBLE ALIGNMENT APPARATUS               FOR AUTOMOTIVE VEHICLES                 ABSTRACT OF THE DISCLOSURE     Two rectangular housings are mounted in a pair of spaced recesses in a garage floor to have cover means thereon  moved to closed positions flush with the floor surface.  Mounted in one end of each housing beneath a first cover is a rotatable wheel-supporting pad, which is slidable longitudinally of the housing, and is reciprocable vertically by a pneumatically operated scissors jack.  Each housing has pivoted on its opposite end a second cover which carries on its inside surface a laser, a mirror, and a conventional alignment chart for denoting toe in, toe out, camber, etc., all of which items are disposed within one section of the housing when the pivotal cover is closed.  When the pivotal covers are swung to upright positions, each laser directs a beam of light upwardly onto the associated mirror, which is included at 45° to the vertical, so that the mirrors direct their beams horizontally through an aperture in tile center of the associated chart and coaxially toward one another.  The lasers, mirrors and charts are adjustably mounted on their respective pivotal covers so that the beams of light can be properly focused.          The apparatus is particularly suited for use with a garage bay of the type having a lift for engaging the frame of an auto to raise and lower the latter.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a pipe joint comprising a first pipe having an end portion engaged as a snug fit in a concentric end portion of a second pipe.  The pipes have, at positions spaced from their adjacent ends, external annular ribs with corresponding internal annular grooves, an annular seal being accommodated in the annular groove of the outer pipe between the outer pipe and the inner pipe.     A clamping ring which spans the annular ribs of the two pipes comprises two arcuate parts connected end to end by a hinge and having at their ends remote from the hinge outwardly turned edge formations which are received in a wedge-shaped channel member and engage relatively inclined opposing side walls of the channel member.  The clamping ring can simply be closed around the pipe joint by relative pivoting of the two arcuate parts and can be retained by sliding the wedging member, in a direction parallel with the axis of the pipe joint, over the edge formations at the ends of the arcuate parts remote from the hinge.
