Abstract: A golf putter head with a cutout for engaging and retrieving a golf ball from the green or other surface without bending over or stooping down. The cutout extends perpendicularly through both the front face surface and the rear surface of the putter head and has an upper surface and a pair of flat, opposing walls that terminate in lower edges to form an opening for receiving a golf ball into the cutout. The cutout walls are tapered toward each other at their upper edges to form a self-holding taper for engaging the golf ball. The cutout is positioned in the heel section of the putter head so that the cutout opens vertically through the sole of the putter head, or horizontally through the heel of the putter head, or at any angle between the vertical and the horizontal.

Abstract: Hair care formulations for cleansing the scalp and hair follicle openings are disclosed which comprises black cohosh extract, and a surfactant selected from the group consisting of sodium C.sub.

Abstract: A process for monoalkylating diphenylamine using a clay catalyst is disclosed which results in a reaction product having substantial amounts of desirable monoalkylated diphenylamine and minimal amounts of less desirable disubstituted diphenylamine and unsubstituted diphenylamine. The disclosed process uses clay catalysts which favor monoalkylation over dialkylation and specific conditions such as reaction temperature, mole ratios of alkylating olefin to diphenylamine, reaction times, and catalyst amounts. Preferred olefins are diisobutylene and linear alpha olefins having from 6 or 8 to 18 carbon atoms. When more than 1 wt. % residual unreacted diphenylamine is present it may be converted to alkylated diphenylamine by reacting with styrene, alpha-methylstyrene or isobutylene.

Abstract: Branched and cyclic N,N-dialkyldithiocarbamyl accelerators for the sulfur vulcanization of rubber have been found to generally perform as well as the corresponding straight chain N,N-dialkyldithiocarbamyl accelerators, but surprisingly do not produce detectable amounts of environmentally undesirable N-nitrosamines.The branched N,N-alkyldithiocarbamyl accelerators are generally represented by the formula: ##STR1## where R is a branched alkyl group, R' is an alkyl group which may or may not be branched or a cyclic alkyl group or an alkaryl or aryl group, X is another thiocarbamyl group of the same general structure, a primary alkylamino group, an alkylthio group, a 2-benzothiazyl group, or a metal ion, and n is an integer of from 1 to 6.

Abstract: An oligomer from diarylamines is disclosed which has desirable antioxidant properties in lubricating oils which contain synthetic ester lubricants. The oligomer is desirable for use at higher temperatures where it has less volatility than simple diarylamines. The oligomer has substantial portions of monosubstituted diphenylamine repeat units which result in linear oligomers. Di and polysubstituted diphenylamines may optionally be present as repeat units. These di and polysubstituted diphenylamines generally react as monofunctional reactants in oligomerization and tend to reduce the number of repeat units in the average oligomer.

Abstract: Disclosed is a method for decolorizing alkylated diarylamines, which have been made using aluminum chloride catalyst, by mixing and optionally heating the colored diarylamine with clay, then separating the decolorized diarylamine from the clay. Alternatively, the alkylated diarylamines, which have been made using aluminum chloride catalyst, may be decolorized by passing the diarylamines through a filter medium comprising clay.

Abstract: Excellent color stabilization as well as fiber integrity is obtained in bright sunlight at relatively high temperature, in polyolefin (PO) articles pigmented with red, yellow, and orange azo and disazo pigments, by combining the pigment with two `large molecule` primary stabilizers, the first an oxo-piperazinyl-triazine based (PIP-T) hindered amine light stabilizer (HALS), and the second, a 3,5-disubstituted-tert-butyl-4-hydroxybenzoate (3,5-DHBZ). The first contains at least two polysubstituted piperazinone rings in its molecule; the second is a hindered phenol with an ester group in the para- position. Stabilization of the PO's color is obtained for as long as the PO articles themselves are stabilized by the combination of primary stabilizers. With the combination, the pigmented articles are not only thermooxidatively and light-stabilized, but there is exceptionally low color fade. Because fibers may be extruded twice for better distribution of pigment, a small amount, no more than 0.

Abstract: Excellent stabilization to bright sunlight, is obtained in polypropylene (PP) fibers pigmented with Red 144, by combining the pigment with N-(substituted)-1-(piperazin-2-one alkyl)-.alpha.-(3,5-dialkyl-4-hydroxyphenyl)-.alpha.,.alpha.-substituted acetamide ("3,5-DHPZNA" for brevity). Stabilization of the red color is obtained for as long as the PP fibers themselves are stabilized by the 3,5-DHPZNA. 3,5-DHPZNA is a known hybrid stabilizer having a hindered amine N-(substituted)-1-(piperazin-2-one alkyl) group at one end, and a hinderd phenol (3,5-dialkyl-4-hydroxyphenyl) group at the other. This particular hybrid, containing a piperazinone group, combined through a disubstituted alpha carbon atom of the acetamide in a single molecule, affords the advantages of each group with respect to its stabilization of the fiber against degradation, but without the expected adverse interaction of each group with Red 144 pigment. With 3,5-DHPZNA and Red 144 pigment, essentially no secondary stabilizer is necessary.

Abstract: The prior art solvent process for the manufacture of an oxo-piperazinyl triazine (PIP-T) compound required carrying out the reaction between an appropriately hindered cyclic amine and cyanuric chloride in the presence of caustic catalyst, in alkylbenzene solution, typically toluene. The chloride ions generated during the reaction, in presence of water present in the reaction zone, produced serious corrosion and resulted in off-color product which had a melt absorptivity greater than 3.5 mL/gm.cm. This "color" in the product made the product generally unmarketable. Another process to make a PIP-T termed "the solventless" process used no toluene solvent, and no caustic but required such a very large excess of amine that the catalytic function of the amine.HCl salt went unnoticed.

Abstract: The present invention is directed to a one part, sealant composition preferably comprising a free isocyanate functionalized polyacrylate. The unblocked isocyanate is surprisingly stable even in the presence of a blocked amine curing agent. Upon exposure to ambient conditions, the blocked amine will react with ambient humidity to provide an amine which in turn will react with the polyacrylate isocyanate, thereby curing the sealant and providing exceptional sealant properties. The most preferred blocked amine curative is a ketimine.
