Abstract: OPTICAL RECORDING MEDIUM AND              METHOD FOR ITS FORMATION               ABSTRACT OF THE DISCLOSURE         An  improved  information  recording medium having a special nitrated dye recording layer.  Information can be recorded in the medium by scanning the recording layer with an intensity-modulated beam of light,  to selectively heat portions of the layer and thereby cause correspon-ding minute explosions in it, yielding a sequence of spaced microscopic pits representative of the information.  The exploded material  contains primarily non-condensable gases  so that very little, if any, non-gaseous residue is deposited on surrounding portions of the medium, and the information is thereby recorded with an improved signal-to-noise ratio.

Abstract: Lock Pin Assembly Abstract A lock pin assembly is movable axially to engage an opening in a pin receiving portion of an indexable apparatus.  The apparatus includes a first member which carries the pin receiving portion and a second member which carries the lock pin assembly.  The first and second members are movable, one with respect to the other, and the lock pin assembly serves to lock the members against movement.  The lock pin assembly is secured to a moving means which moves the pin assembly into and out of engagement with the pin receiving portion.  The first and second members are subjected to severe loading and vibrations which attempt to move the first member with respect to the second member.  The lock pin assembly resists the loading and vibrations and isolates the moving means from bending loads imposed upon the pin assembly.

Abstract: "PROCESS FOR REMOVING CONTAMINANTS FROM WASTE LUBRICATING OIL BY CHEMICAL TREATMENT" A process is provided for removing contaminants from waste lubricating oil. The waste oil is contacted with one or more of the pretreatment chemicals ammonium sulphate, ammonium bisulphate, ammonium dihydrogen phosphate, diammonium phosphate, calcium hydrogen phosphate, phosphoric acid, calcium sulphate, aluminum sulphate, and magnesium sulphate. The contacting step is performed at a temperature in the range of about 650 to 725.degree.F. The oil mixture is then filtered to remove the contaminants. The pretreatment chemical is preferably added in the absence of water, thereby reducing the amount of water to be removed from the oil.

Abstract: ABSTRACT OF THE DISCLOSURE         Platinum-olefinic hydrocarbon complexes, e.g.  platinum-styrene complexes are prepared by reacting a platinum halide with styrene or ring-substituted styrenes in the presence of a basic material for a sufficient amount of time to form a platinum-olefinic hydrocarbon, e.g. platinum-styrene, complex having more than one and less than four gram atoms of halogen per gram atom of platinum.  These platinum-olefinic hydrocarbon, e.g. platinum-styrene complexes may be used to promote the addition of organosilicon compounds having at least one   SiH group per molecule to a compound containing aliphatic unsaturation.  Thus, the above described complex may be used   in a process for the addi-tion of an organosilicon compound containing silicon-bonded hydrogen to an organic compound having carbon-carbon unsaturation which comprises forming a mixture containing the organosilicon compound having silicon-bonded hydrogen and an organic compound having carbon-carbon unsaturation.          It has been found that a very small amount of the catalyst will effect the desired reaction between the silicon-bonded hydrogen compound and the unsaturated organic compound.  In addition, it has been found that the catalyst retains its level of activity even after storing for pro-longed periods of time at elevated temperatures.  Furthermore, the activity of the catalyst is such that silicon-bonded hydrogen containing organopolysiloxanes and vinyl containing-organopolysiloxanes can be cured very rapidly and therefore used as potting or encapsulating compositions for electrical components on assembly lines,

Abstract: ABSTRACT         A method and an apparatus are disclosed for heating process air for industrial purposes to a pre-determined temperature.  The method comprises passing a first air-flow portion through a plasma generator and thus heating said portion to a temperature suffi-ciently high to cause the ionization of nitrogen and oxygen in the portion and thus form a plasma gas, immediately thereafter adding to said plasma gas a material containing carbon and/or hydrocarbon in sufficient quantity that when said material is reacted with the plasma gas, the ratio CO+H2/CO2+H2O is at least 0.1 thereby substantially avoiding the forma-tion of nitrogen oxide; and immediately thereafter mixing with the plasma gas, with its content of material containing carbon and/or hydrocarbon, a second air-flow in such proportion that the pre-determined temperature is achieved in the final air mixture.

Abstract: ABSTRACT OF THE DISCLOSURE         A multi-section crane boom is provided with a fly section and a jib section which may be erected and supported by a mast and pendants on the end of the boom to extend the effective length of the boom.  When the fly section and jib section are not used they are stored on the boom, the fly section being supported alongside of and generally parallel to the boom and the jib section being supported in position below the fly section.  The fly section can be mounted on the end of the boom alone while the jib section remains in stored position, or, alternatively, the fly section can be mounted on the boom and the jib section can be mounted on the outer end of the fly section.  A pair of compact hook shaped resilient connectors serve as backstops which prevent the fly from pivoting in excess of 5° upwardly past longitudinal of alignment with the boom axis when the boom is in a near vertical position.  The resilient connectors also permit easy attachment of the pendants when slack, and further act as shock absorbers during stowage of the fly and during pivotal erection of the jib relative to the fly in the event the components of the crane axe improperly adjusted or the operator negligently operates the machine.

The epoxides derivable from the halohydrin of Formula (I) are other monomers of this invention.     -ii-The monomers are soluble in common organic solvents and comonomers.    The invention is also directed to addition polymers of these monomers and to methods of producing both the monomers and the polymers.  The halohydrin monomers and the polymers are stable at acid pH values, although capable of reacting with materials reactive with the hydroxyl and/or halide groups. Upon heating, they are self-reactive and can become cross-linked.  At alkaline pH values they become self-reactive; the polymers crosslink slowly even at room temperature, with a crosslinking rate increasing rapidly with temperature.  The monomers are particularly efficiently incorporated into co-polymers.

Abstract: ABSTRACT OF THE DISCLOSURE     A positive drive having a housing (10) retaining a pair of spaced drive clutches (54) and (56) used to lock axles (18) and (20) respectively to housing (10) for one-to-one rotation.  The clutches move from the engaged to the disengaged mode via axial movement of drive couplings (30) and (32) which are forced to the respective engaged positions by a shaft (48) secured for rotation with the housing.  The shaft acts on cams (38) and (40) on the drive couplings to cause rotational and axial movement of the couplings.  Rotational movement of one drive coupling relative to the other drive coupling is prevented by a balking clamp (76).  The clutches (54) and (56) are inserted within the housing through a window (14).  The axles are retained by "C" clips (80) contacting spline couplings (26) and (28).
