Abstract: Disclosed is an extension platform for securement to a conventional table saw that allows for the accurate cutting of larger workpieces. The extension platform is formed from a support wall with a resistant free, height adjustable, material rest to allow movement of an oversize workpiece without marring the workpiece. The extension platform is secured to the table saw by a rail that fits through a guide mounted on the table saw and used for support of an alignment fence. The support platform can be stored adjacent to the table saw without interfering with the table saw operation and easily deployable by use of casters wherein an extension rail can be locked to the guide to prevent movement of the extension platform.

Abstract: A method for the isomerization of a mixture of vinyl and vinylidene olefins having 10 to 35 carbons atoms to form a mixture comprising both di- and tri-substituted internal olefins including deep internal olefins.

Abstract: A catalyst composition effective for isomerizing alpha-olefin to internal olefin and a process for conducting such isomerization using the catalyst composition are described. The catalyst comprises the combination of an alkyl aluminum alkoxide and a cobalt salt of an organic carboxylic acid or reduced form of such cobalt salt wherein the number of alkoxide groups in the alkyl aluminum alkoxide is sufficiently greater than 1 and sufficiently less than 3 per aluminum atom to provide an active catalyst for catalyzing such isomerization. Typically the alkyl aluminum alkoxide has the formula R.sup.3.sub.n Al(OR.sup.4).sub.p where R.sup.3 and R.sup.4 are the same or different and are alkyl, n is from 0.75 to 1.85, p is from 1.15 to 2.25 and the sum of n and p is 3. The isomerization process using such catalysts proceeds rapidly and requires no addition of hydrogen to enhance the reaction.

Abstract: A process for producing an internal olefin of the formula ##STR1## where R.sup.1 and R.sup.2 are the same or different and are either a hydrogen or an alkyl and m is an integer of from 0 to 20 comprising contacting a vinyl or vinylidene olefin of the formula ##STR2## where R.sup.1, R.sup.2 and m are as previously defined, with a catalytically effective amount of a mixture of i) an aluminum compound of the formula R.sup.3.sub.n Al(OR.sup.4).sub.p where R.sup.3 and R.sup.4 are the same or different and are alkyl, n is an integer from 0.75 to 2.25, and p is an integer from 0.75 to 2.25, the sum of n and p being 3, and ii) a cobalt (II) salt of an organic carboxylic acid, at a temperature of from about 25.degree. C. to about 250.degree. C. whereby a major amount of said internal olefin is produced and only a minor amount of a tri-substituted internal olefin.

Abstract: The invention provides high elongation thermally bonded nonwoven fabrics which exhibit elongation of at least about 130% in the cross-machine direction. The fabrics of the invention include a nonwoven a web of polyolefin staple fibers having an elongation of at least 400 percent, and a multiplicity of discrete thermal bonds throughout the web to provide a bond area of from 8 to 25 percent of the area of the fabric.

Abstract: An engine cooling apparatus positioned between a coolant radiator and air conditioning condenser of an associated automotive vehicle, with the cooling apparatus including a plurality of nozzle members between the condenser and radiator structure, with a fluid control operative through a control relay to effect actuation of a pump to direct fluid flow to the nozzle members upon sensing a predetermined coolant temperature within the radiator.

Abstract: Aluminum alkyls are oxidized to aluminum alkoxides using a cobalt catalyst to increase the rate of oxidation. Alcohols can be prepared by hydrolysis of the aluminum alkoxides.

Abstract: This invention povides to a process for making an aluminum trialkyl product which process comprises reacting a mixture comprising, (i) an aluminum alkyl feed which contains one or more aluminum alkyls represented by the formula R.sub.3 Al, where R represents a C.sub.2 to C.sub.20 straight chain alkyl radical and each R can be the same or different, the alkyl radicals in said aluminum alkyl feed having an average chain length of at least about C.sub.

Abstract: In an apparatus for generating a fine dispersion of particles in a gas, a body (47) for containing the gas has an inlet (59a, 59b) and an outlet (60) for passage of the particles. Nozzles (55) are provided to direct a plurality of jets of gas through the body (47). The body (47) is maintained at an elevated temperature by a heating element (49).

Abstract: Amide compounds such as N-(phenyl)propenamide and N-(phenyl)-2-methylpropenamide are added to certain diene polymers such as SBR, NBR and natural rubber, preferably prior to compounding with reinforcing agents such as carbon black, thereby improving the hardening resistance of the subsequently sulfur vulcanized polymer.

Abstract: The doffing apparatus services a textile machine having a row of bobbin-receiving spindles extending in its length direction, and includes an elongate bobbin grasper member which projects generally parallel to the row of spindles and is movable relative thereto between elevated and lowered positions for the purpose of transporting bobbins to and from the spindles. The stop motion device is actuable by impedence of the aforesaid movement of the bobbin-grasper member, as reflected by relative movement that then transpires between components which support such member.

Abstract: The viscosity of a high viscosity latex, compounded or uncompounded, is lowered by the addition of certain phenolic compounds such as 2,4,6-tris-(1,1-dimethylbutyl)-phenol.
