Abstract: SCAVENGING HYDROGEN SULFIDE FROM HYDROCARBON LIQUIDS           Abstract This invention relates to scavenging hydrogen sulfide from hydro-carbon liquids.  For this purpose, the hydrogen sulfide in the liquid is contacted with iron oxide particles typically containing a crystalline phase of Fe3O4 or Fe2O3 and combinations thereof together with an amor-phous Fe2O3 portion, and having a surface area of at least 3.5m2/g. Where for example, substantially anhydrous kerosene contains hydrogen sulfide in an amount in excess of 20 ppm, such hydrogen sulfide content is reduced to less than 10 ppm, thereby rendering it safe and salable.

Abstract: Abstract of the Disclosure A tire mounting method and tool for use in mounting a large, heavy off-highway pneumatic tire onto a dual-flanged single piece drop center wheel rim of the type having at each rim flange a re-entrant lip protruding radially inwardly toward the axis of the rim.  The tool has a main frame adapted to be placed upon one side of the wheel rim when the rim is resting horizontally on its axially opposite other side on the ground in a free, unfixtured condition.  The frame is longer than the inside diameter of the rim flange lip and slidably rests thereupon, and also slidably grips the rim lip.  A pair of arms each are pivoted at their inboard ends to the main frame at a common pivot point for pivotal counter-rotational movement on opposite sides of the main frame about a pivot axis parallel to the rim axis.  A pair of tire-bead-engaging shoes are carried one on each of the outboard ends of the arms. A pair of hydraulic rams are interconnected one between each of the arms and the main frame for counter-rotating the arms so as to propel said shoes in arcuate paths adjacent and outwardly of the rim flange.          The rams are operably interconnected for fluid pressure actua-tion in a parallel fluid circuit from a common hydraulic pressure fluid source such that in operation of the tool the arms are pivotal about an axis generally co-incident with the axis of the wheel rim, and the entire tool is likewise bodily rotatable about this axis to re-balance unequal tire-bead reaction forces exerted on the shoes.

Abstract: ABSTRACT     .beta.-Chloroalanine is prepared by reacting in an aqueous medium an aziridine-2-carboxylate with hydrogen chloride in an amount of 2.0-5.0 moles per mole of the aziridine-2-carboxyalte and causing the thus-formed .beta.-chloroalanine to selectively crystallize out from the liquid reaction mixture.  Since the solution recovered after the isolation of the crystallized .beta.-chloroalanine still contains .beta.-chloroalanine and by-produced .alpha.-chloro-.beta.-alanine dissolved therein, they may be converted into an aziridine-2-carboxylate by treating them with a base to recirculate it for reuse.

Abstract: Case 5247 ABSTRACT OF THE DISCLOSURE                    Polyacetylene production The present invention relates to coherent poly(acetylene) films and to a method of producing such polyacetylenes.  The process comprises solvent casting a solution of a polymer of the general formula (V) derived from a precursor (IV), and transforming the pre-cast, polymer (V) into a poly(acetylene) (III) film and a by-product (VI) at a temperature between 20 and 200°C at reduced pressure.  The poly(acetylene) thus formed has a substantially higher density than the poly(acetylene) polymers produced hitherto.  The morphology of the poly(acetylene) produced is that of a thin, coherent solid film with no voids and, no basic structural units are visible even at a magnification of 10,000 times.  The polymers also have a lower crystallinity than those produced by conventional methods.

Abstract: Abstract of the Disclosure A silica hydrogel containing chromium is aged under conditions such that at least a portion of the aging is carried out at a pH within the range of 7 to 9.  The resulting hydrogel is converted to a xerogel by treating with a volatile organic liquid.  The desired pH can be obtained either by adding a basic material such as ammonia to the hydro-gel prior to or during the aging process or by using a chromium component which inherently gives a higher pH and/or resists the natural tendency for the pH to decrease during aging.  An example of such a chromium com-pound is chloropentammine chromium(III)chloride. The resulting catalyst on activation is particularly suitable for olefin polymerization under conditions where higher melt flow polymer is desired.

Abstract: ABSTRACT The bag closing apparatus includes a horizontal plate for supporting a coiled strip of bag closure tags, a channel having a width corresponding to the thickness of the bag closure tags and a height greater than the height of the bag closure tags. The channel terminates with are inclined surface such that the upper surface of the tag can be exposed with the entrance to the opening within the tag lying substantially flush with the inclined surface.  When a bag to be closed is slid manually downward along the inclined surface, the crushed end of the bag enters the opening in the closure tag and is seated therein. The bag and the closure tag are then manually slid until the closure tag leaves the channel and is broken from the strip. In the process of clearing the first closure tag,  engaged with a bag,  from the channel,  the next following closure tag is brought into position to receive the next bag to be closed.
