This invention relates to a polyester resin comprising (A) from about 5% to about 50% by weight reactive diluent and (B) from about 50% to about 95% by weight of an unsaturated polyester resin prepared from at least one component selected from the group consisting of (i) from about 0.5% up to about 8% by mole of a polyhydric alcohol, having at least three hydroxyl groups, and at least one transesterification catalyst, (ii) from about 2% up to about 12% by mole of a reaction product of a polyol and a fatty carboxylic acid, and (iii) from about 2% up to about 12% by mole of a fatty reactant selected from the group consisting of a fatty primary alcohol, a fatty epoxide, a fatty monocarboxylic acid and mixtures thereof, wherein each member of the group has up to about 100 carbon atoms. In another aspect, the invention relates to mixtures of the above polyester resins with conventional polyester resins. Methods of reducing volatile organic compound emissions are also part of the invention. The present invention provide resins and methods which have low emissions of volatile organic compounds and when used in curable compositions have good gel times and final cured properties.

The present invention provides a color concentrate comprising (a) at least one resin selected from the group consisting of a polymer of a diene, a rosin material, a coumarone-indene resin, a polymer of vinyl aromatic monomer having an M n of from about 500 to about 4000, a wax and a mixture of two or more thereof, (b) at least one resin selected from the group consisting of a copolymer of an olefin and an acrylate or a methacrylate, a polymer of a vinyl aromatic monomer having an M n of at least about 10,000 and a mixture thereof, and (c) at least one colorant.

Color concentrates and polymer compositions containing the same, and

A fruit thinning apparatus for reducing fruit bruises caused when thinned fruit is discarded and strikes fruit left on the tree. The apparatus includes a chute having an upper portion which is supported upon a person's torso using a harness. A lower portion of the chute extends along the person's leg and is held in position by leg connectors, preferably at both the upper and lower leg. The outlet end is provided with an adjustable cuff to accommodate different heights of people. A cinch is used along medial portions of the chute to allow thinned fruit to be held and then released when the outlet is in a position where damage will not occur.

Fruit thinning apparatus

This invention relates to a multilayer thermoformable structure comprising (A) at least one cap layer and (B) at least one core layer, and polymer compositions for making the same. The multilayer structures and polymer compositions of the invention are useful in preparing thermoformed articles and are particularly useful in preparing liners for refrigerators and freezers. The multilayer structures and the polymer composition have good thermoformability and chemical resistance. The multilayer structures and the polymer composition have good surface properties including a glossy finish. Further these materials are compatible with new blowing agents, such as the hydrochlorofluorocarbons and hydrofluorocarbon blowing agents, which are more environmentally friendly. The layers of the multilayer structure do not require a glue layer.

A peristaltic pump which utilizes a length of elastic tubing in effecting pumping action comprising a frame; a pumping chamber on the frame including peristaltic pumping means for progressively squeezing and releasing consecutive portions of an intermediate section of the tubing to pump fluid in the tubing in a predetermined direction; and tubing feeding means on the frame comprising gripping means to engage the outer periphery of the tubing, on at least one section adjacent to the tubing intermediate section, and feed the tubing through the pumping chamber in the predetermined direction at a controlled rate during pumping of the fluid. Preferably, the means to engage and feed the tubing comprises a powered wheel or roller mechanism having a friction gripping surface to controllably feed the tubing into the pump chamber. The roller may be configured to engage both tubing being fed into and tubing being fed out of the pump chamber.

Peristaltic pump

The present invention relates to novel compounds corresponding to the formula: ##STR1## wherein R.sub.1 and R.sub.4 may be the same or different, and each is a lower alkyl radical; R.sub.2 and R.sub.3 may be the same or different, and each is a substituted piperidine radical; M is equal to the total number of monomer units in the polymer chain, and is of a magnitude sufficient to provide a polymer having a molecular weight of at least 500; W is equal to at least 0.5, X is equal to at least 0.1 but not greater than 0.2, Y is equal to at least 0.1, Z is equal to at least 0.05 but not greater than 0.2, and W plus X plus Y plus Z is equal to 1. These novel compounds are useful as stabilizers for a wide variety of organic materials and are prepared by transesterification of a suitable acrylate-methacrylate copolymer.
