Abstract: An electrocoating composition containing a polymer having pendant amine groups, an alpha-, beta-ethylenically unsaturated carbonyl cross-linking agent, and an ultraviolet photosensitizer can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. The amine groups of the polymer are protonated to render the polymer water dispersible prior to electrodeposition and upon electrodeposition the amine groups become de-protonated. The cross-linking agent cross-links the polymer upon ultraviolet irradiation of the electrocoated cathode substrate to form a fully-cured electrodeposited coating on the cathode substrate.

Abstract: Powder paint coatings of this invention are particularly suitable for ultraviolet curing and comprise specific spatial arrangements of ethylenically unsaturated polymers. The polymers contain pendant double bond unsaturation in combination with an epoxy adduct spaced on the polymer chain from a polyester adduct. The powder paint is free of cold flow and can be applied electrostatically or physically to metal substrates, moderately heated to obtain desired flow out, and then cross-linked or cured by ultraviolet irradiation.

Abstract: An ultraviolet radiation curable coating composition containing a certain adhesion promotor for adhesion to metal substrates. The ultraviolet curable coating composition comprises an ethylenically unsaturated binder vehicle, about 10% to 40% by weight of a certain high T.sub.g (glass transition temperature) adhesion promotor polymeric additive, and an ultraviolet sensitizer.

Abstract: A reconstituted food product is prepared from a natural food item by mixing such food item in finely-divided form with water and an aqueous algin dry mix containing a carbohydrate, forming the resulting dispersion into a predetermined shape, and contacting said shape with a gelling solution containing calcium ion for a time period sufficient to harden the algin containing dispersion. The invention has particular applicability in the preparation of a pimiento containing product for use in stuffed olives.

Abstract: A one-step process for synthesizing water soluble self-curing polyurethanes is achieved by co-reacting certain monomers under controlled conditions to form a blocked, water soluble polyurethane which can be subsequently dispersed in water. The polyurethane polymer is substantially free of high molecular weight hydrocarbon chains and essentially comprises all polyurethane units and is adapted to self-cross link upon being subjected to heat. The polymer is particularly suitable for producing polyurethane protective coatings which exhibit substantially increased film hardness, abrasion resistance, as well as other desirable film integrity properties.

Abstract: A beta-, gamma-unsaturated cycloalkenol contaminated with an acid-forming moiety is catalytically isomerized to a cycloalkanone in the presence of copper chromite catalyst and an insoluble base which suppresses the acid-forming moiety during the isomerization.

Abstract: An acid-solubilized aqueous dispersion particularly suitable for use in the cathodic electrocoating art and stable up to pH of about 9 comprises the product of reacting substantially all of the epoxide groups of a polyether diepoxide with from about 1.25 to 2 moles of a polyamine having from 2 to 5 amine groups to form a precursor adduct and subsequently reacting this precursor adduct with about 0.2 to 2 moles of a mono-epoxide having a hydrolysis-resistant normal alkyl group of at least 4 carbon atoms to form a substantially epoxy-free polyamino polyhydroxy polyether resinous adduct, a sufficient proportion of the amine groups of said polyamine being primary or secondary to provide an amino hydrogen for reaction with every epoxide group of both the diepoxide and the mono-epoxide, and about 0.05 to 0.4 weight parts (per part of the resinous adduct) of an aminoplast resin having at least about one gram-equivalent of carboxylic acid groups with pK.sub.

Abstract: Glyceride oil contaminated with soap is hydrogenated in rapid fashion in the presence of nickel hydrogenation catalyst and of copper chromite adjunct catalyst, wherein the proportion of adjunct catalyst is adjusted broadly proportional to the soap concentration so that the hydrogenation proceeds substantially insensitively to said contaminant soap.

Abstract: Glyceride oil is catalytically hydrogenated in rapid fashion to produce a stearine product.

Abstract: A cartridge for housing a supply of ribbon for typewriters or like machines. The cartridge includes an arm extending therefrom to guide the ribbon from the cartridge to the typewriter print point and to reverse the direction of the ribbon for guiding the ribbon back to the cartridge which is supported on a machine rigid frame on one side of the print point. The arm is provided in several embodiments of the invention, with a tab-like extension near its end to be engaged by the typewriter lift mechanism whereby it may be driven by the lift mechanism to carry the ribbon from a point adjacent the print point to the print point as a ribbon vibrator.

Abstract: Aqueous heat-curable coating compositions comprise polyester resin, aminoplast resin, and an allyl ether of a diol or triol wherein the allyl ether alcohol functions as a conventional co-solvent for aiding in dispersing the polyester resin in water and under curing conditions becomes an integral part of the cured coating.

Abstract: A rotatable disc type printer for use in conjunction with a typewriter having a movable carrier. The type element or characters are carried on radially extending petals and are arranged at varying distances from the center of disc rotation so as to define a circumferential spiral path. The angular placement or position of each petal or spoke is determined by the following formula: angular placement of i.sup.th petal=360.degree./n .+-. tan .sup.-1 id/nL where n defines the total number of petals, d is the character spacing and L is the minimum distance from the center of disc to the print point. The length or distance from the center of disc rotation to the type character or element is defined by: L.sub.i (length for i.sup.th element=.sqroot.i L.sup.2 +(i/nd).sup.2 where i/nd ids the linear distance of travel of the disc center while rotating from a home position to the position for printing the character carried by the i.sup.th petal.
