Abstract: INCINERATION METHOD AND SYSTEM     ABSTRACT OF THE DISCLOSURE            The following disclosure teaches ways and means for incinerating organic wastes in a multiple hearth furnace equipped with an afterburner.  In the furnace, the wastes are pyrolyzed in an oxygen deficient atmosphere which is regulated to only partially complete the oxidation of the organic substances which are pyrolyzed from the wastes.  In the afterburner, air is intro-duced to complete the oxidation of the partially oxidized substances carried by gases and vapors from the furnace.  The air supply to the afterburner is controlled so that, at temperatures above a predetermined temperature, the quantity of air introduced is increased with increasing temperatures and is decreased with decreasing temperatures.  In other words, the pyrolyzing furnace is caused to operate with a defi-ciency of air over its operating range, while the afterburner is caused to operate with excess air and the amount of excess air supplied is used to control the operating temperature by quenching.

Abstract: ABSTRACT OF THE DISCLOSURE       This disclosure is of an article exchange mechanism of the type suited for use in exchange of tools or workpieces in a machine tool.  The mechanism is asymmetrical in the sense that each of the positions between which articles are exchanged may be at a different distance from the origin of coordinate axes extending through these positions.  A support structure or hub is mounted for rotation on an axis which does not pass through the origin with a pair of exchange arms mounted at diametrically opposed posi-tions on the hub.  The arms rotate about axes transverse to the hub axis as the hub rotates so that the positions in space of the arms are exactly exchanged.

Abstract: VENT TUBE MEANS FOR A CRYOGENIC CONTAINER            ABSTRACT OF THE DISCLOSURE         A vent tube having a first branch and a second branch for use in a cryogenic container through which the interior of the container is communicated to the atmosphere.  The cryogenic container is adapted to receive a fixed volume of cryogenic fluid at a uniform temperature and density.  In a filling operation, the first branch of the vent tube contacts the cryogenic fluid and carries a portion of the fluid to the atmosphere to Inform an operator that the capacity of the container has been reached. After the container is filled, the temperature in the stored cryogenic fluid rises.  As the temperature changes, distinct stratified layers of fluid of different densities and temperatures can be measured in the container.  The change in temperature causes the cryogenic fluid to expand and submerge the adjacent first branch of the vent tube.  Thereafter, the second branch, which is located at the gravitational top of the container, provides a flow path to the atmosphere for the top layer of cryogenic fluid to assure that the higher density cryogenic fluid is retained in the container means.

Abstract: Abstract of the Disclosure An automatic control for continuing idle operation of an internal combustion engine, particularly a diesel motor, to pro-vide proper engine conditioning before the engine is shut down. Automatic control circuitry is added by connection to the contacts of a conventional manual control switch for the engine. Normally open contacts of a relay are pre-set during engine use to bypass the manual control switch for a predetermined time following sub-sequent opening of the switch.  A first electronic detector moni-tors the closing of the switch, while a second electronic detector monitors its opening. The two detectors operate both the relay and an electronic timing mechanism. The timing mechanism opens the relay contacts following a predetermined period after the opening of the manual control switch. In this way shutdown of the engine is accomplished  electronically as an automatic function following manual opening of the usual key switch.

Abstract: ABRASIVE BRUSHES AND METHODS OF MAKING SAME                  Abstract of the disclosure An elongate, abrasive strip element is produced by winding an abrasive monofilamenr, of bundles thereof, back and forth in a zigzag pattern from side to side of the strip, and chain stitching together adjacent transverse sections of the  mono-filament, or bundles thereof.  The resultant strip is easily rolled or coiled about a transverse axis, but resists bending about a longitudinal axis, whereby it can be manipulated readily to form brush races of various configurations.  The warp yarns which are used to produce the chain stiches may be produced on a knitting machine which can be cammed to vary the number of stitches between adjacent transverse strands of the monofilament wefts, thereby selectively to vary the density of the brush races produced from the strips, and asso to vary the configuration of the abrasive strip itself (i.e. to produce it in linear form, circular, truncated-conical, etc.).  The linear form of the strip may be severed medially of its edges to form two, identical bristle strips, each of which may be wound in convolute form, for example, and may be embedded at one side (e.g. by molding) in an elastomeric base to form a disc type brush.  Other brush con-figurations are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE             This application describes a rotation-only CT scanner with bean deflection; the deflection and the rotation being so related as to permit the derivation of absorption data in groups focussed on respective "pivot points" outside the detector locus.          Data derived from different detectors, but focussed on the same pivot point, relate to groups of paths, some of which overlap, and the overlap is used to compare the performances of different detectors.   To reduce data handling, data provided by adjacent detectors can be combined.
