A method of opening uni-valve and bi-valve shellfish by exposing the region of the shell of a shellfish adjacent the adductor muscle to a stream of hot air for a period sufficient to detach the adductor muscle and facilitate opening of the shellfish. The method involves supplying between 25 to 450 kilojoules of energy to the shell of a shellfish within a period of between 5 to 60 seconds. The temp...

A reciprocating saw includes a system (10) that permits the saw blade to be mounted so that it is at an angle (i.e., so that it is not parallel) to the axis of reciprocation of the saw. The system (10) permits the blade (6) to be rotated about its axis of reciprocation, and in some embodiments the angle between the blade axis (B) and the axis of reciprocation of the saw (A) may be varied through a...

The wire 4, intended to form a carcass reinforcement, is wound in contiguous hoops on a rigid core 1, by means of an eyelet 33 fixed to a chain 30 mounted on pulleys 31, so as to flank the core 1. The eyelet 33 carries out a to-and-fro movement around the core 1 so as to position, progressively and in a contiguous manner, a hoop at each forward stroke and a hoop at each return stroke.

A self-supporting adhesive sheeting material useful in making blanks for laminated windows comprises a continuous web (10) which has a uniform thickness profile (A, B) across at least 20 % of its area extending from each edge of the web and a wedge-shaped thickness profile (C, D) which decreases in thickness from the area of uniform thickness to the center of the web, and a process comprising extr...

Degradable Films There is a need for degradable films, particularily in agricultural mulch applications. The present invention provides for films having a controlled life from 30 to 160 days. The film comprises photodegradable sheet material having a thickness from 0.1 to 10, preferably, from 0.2 to 5, most preferably from 0.3 to 1.0, mils and comprising a polyolefin sheet and from 50 to 1,000 par...

The method consists in grinding together clinker of Portland cement, calcium sulfate, mineral substances and solid modifier with the organic water reducer component up to obtaining a specific surface of 350-383 m2/Kg, initiating the chemical reaction between the first ingredient and the last ingredient which takes place during a grinding operation, and treating with water vapor the resulting produ...

The method consists in grinding together, in a tubular mill, clinker of Portland cement, mineral substances, calcium sulfate, solid modifier with the organic water-reducer component, and in conducting the chemical reaction between the first ingredient and the last ingredient, as well as the discrete introduction of water in the tubular mill, said introduction being carried out by injection into th...

A method of producing a polysaccharide foam is provided. The method comprises mechanically foaming an aqueous solution of a soluble polysaccharide and thereafter reacting the foam to produce stable foam. Typically, the soluble polysaccharide is an alginate, hyaluronate, carrageenans, chitosan or starch.

This invention relates to the improvement of rubber-to-metal adhesion and adhesion retention in sulfur vulcanizable, metal reinforced rubber compositions via the use of substituted pyrimidine and triazine adhesion promoters of Structure (I). (* CHEMICAL STRUCTURE *) (I) wherein A is N or C-H, X, Y and Z are independently selected from the group consisting of chloro, (* CHEMICAL STRUCTURE *) whe...

Polyoxylalkylene esters and amides of alk(en)yl succinic anhydrides, of the formulae (I) YA1.OC(HR)CC(HR1)CO.A(CmH2m0)n.R2 and (II) YA1.OC(HR)CC(HR1)CO.A(CmH2m0)n.CpH2pA.CO(HR1)CC(HR)CO.A1Y where R, R1, A, A1, Y, R2, m, n and p are as defined, particularly where the alk(en)yl group is a C14 to C22 group, are effective surfactants. They are especially notable because, very surprisingly, the cloud p...

This invention relates to a continuous ultrasonic method for breaking the carbon-sulfur (C-S), sulfur-sulfur (S-S), and if desired, carbon-carbon (C-C) bonds in a vulcanized elastomer. It is well known that vulcanized elastomers having a three-dimensional chemical network, cannot flow under the effect of heat and/or pressure. This creates a huge problem in the recycling of used tires and other ela...

A method is described for making colored backed film material using a polyvinyl fluoride (PVF) film (90) having a first face and a second face opposite the first face. The method comprises the steps of coating the first face of the PVF film (90) with an ink-receptive coating (65). A carrier is then statically laminated to the second face of the PVF film. Using a rotary web (68) printing apparatus ...

Compositions comprising (a) an ethylene-mixed unsaturated ester copolymer or (b) two or more ethylene-unsaturated ester copolymers differing, for example, in their ester chains improve the low temperature properties of fuel oils.
