According to one aspect of the present invention, an improved method for preparing acrylic copolymer resins is provided in which the polymerization solvent comprises an alkanoic acid alkyl ester having a total of from about 7 to 12 carbon atoms per molecule. The monomers comprise hydroxy-substituted alkyl (meth)acrylates, and non-hydroxy substituted alkyl (meth)acrylates, and the process provides an improved method for forming low molecular weight acrylic resins useful as components in high soli...

A chlorinated ethylene-alpha olefin-nonconjugated diolefin terpolymer having a chlorine content of from about 0.5 to 14 percent by weight characterized by superior viscosity stability on storage or exposure to elevated temperatures is obtained by chlorinating an ethylene-alpha olefin-nonconjugated diolefin terpolymer wherein said nonconjugated diolefin is an acyclic nonconjugated diolefin characterized in that one olefinic bond is monosubstituted and terminal and the other olefinic bond is trisu...

A superior yo-yo toy exhibiting characteristics of a lengthened spinning time for performing tricks while retaining characteristic of returning to the hand of the operator when desired; and automatic return to the operator when the yo-yo rotational rate has slowed to a predetermined rate. The yo-yo string is attached to a free-spinning bearing surrounding the axle, the bearing operably connected to a centrifugal actuated spring loaded clutch mechanism so that when the yo-yo rotational rate slows...

A bifurcated graft is formed from a series of individual components which are intraluminally delivered apart from one another and then assembled to form a fully supported structure. The modular system includes a base member and one or more crafts connected thereto. The base member preferably includes a portion which gradually increases in diameter. A tubular device for inserting the components of the modular system and a method employing the modular system for repairing an abdominal aortic aneur...

A Yo-Yo formed of an axle and a pair of complimentary body segments, disposed in opposed relationship on the axle. Each body segment includes an inner and outer plastic shell having at their peripheries, concentric spaced annular rings which intermesh with each other. The inner shells have holes through which the axle projects. The outer shells each include a central hub with a metal sleeve which receives the end portion of the axle. The weight of the Yo-Yo is disposed essentially in the periphe...

A sanding machine with complementary upper and lower sanding heads which have fast moving abrasive belts trained about and constantly shifted edgewise along superimposed contact drums between which the work is fed in a manner whereby the parallel narrow zones of work performing engagement of the abrasive belts with the opposite sides of the work extend at an oblique angle of not more than 75.degree. to the lengthwise dimension of the work.

A multi-layered packaging container superior in crack resistance, said container being made up of an outer layer of thermoplastic resin and an inner layer of saponified product of ethylene-vinyl acetate copolymer characterized in that the ethylene content is 25 to 60 mole %, the degree of saponification of the vinyl acetate component is higher than 96 mole %, the melt viscosity index is lower than 1, the specific gravity (d) is in the range specified by the formula (1) below, and Y.sub.1 and Y.s...

The present invention is directed to nutritionally superior cheese products and their methods of manufacture. More particularly, this invention is directed to the manufacture of nutritionally superior cheese products having at least two phases wherein at least one phase is cheese (e.g., process cheese, uncured natural cheese, cured natural cheese, and the like) and at least one phase is a second edible phase (e.g., a cheese different from the first phase, vegetables, meats, mixtures of vegetable...

A superior cymbal mounting structure including a tubular screw member fixed to a center pull rod of a cymbal stand by a screw bolt and a wing nut, a lock nut threaded onto the tubular screw member to fix a superior cymbal to the tubular screw member between two sponge packing rings, wherein a packing block is mounted in a chamber in the lock nut and stopped against the periphery of the tubular screw member by a tightening up screw to fix the lock nut and the tubular screw member together.

A high performance yo-yo displays extended spinning time and is easy to use even by a beginner. The yo-yo includes two yo-yo halves connected by the axle. A spool formed from low friction polymeric material is mounted for free rotation on the axle and the yo-yo string is attached to the spool. When the yo-yo spins, the axle rotates freely within the spool. The axial play of the spool on the axle and the space between the yo-yo halves adjacent the spool are subject to certain critical values whic...
