The specification describes a method and apparatus for processing bivalve shellfish, particularly scallops. The two shells are first parted by a small amount and a cutting tool is inserted to detach the shellfish from one of the shells. The two shells are then separated. The shell having the shellfish attached is rotated about an axis passing through the center of the edible portion and the offal ...

1. A process for the preparation of a resilient foam based on a melamine/formaldehyde condensate by foaming an aqueous solution or dispersion, which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent, with or without conventional additives, and then curing the foam, wherein a) the concentration of the precondensate in the mixture of preconden...

In repairing articles of natural rubber or elastomer predominantly of natural rubber with cured polymer or prepolymer (polyurethane/polyurea), adhering advantages are obtained especially at elevated temperatures when the damaged area is treated with halogen-containing oxidant dissolved in 1,2-dichloroethane instead of other solvents.

A valve 20 permitting relatively free flow in one direction but restricting flow in the other direction comprises a housing 22 in which a plunger 22 and a piston 40 are reciprocally slidable and are biassed apart by a spring 24. The piston 40 has a through passage 42 closed by a check valve 45 which is bypassed by a restricted passage 51. A projection 53 on the plunger 22 opens the check valve 45 ...

An apparatus for atomization of high temperature melts to from very finely divided powder. The apparatus has a ceramic central melt delivery tube. Melt is introduced at the top and exits at the bottom. At the exit surface a high velocity gas impinges on the melt to atomize the melt into fine particles. The bottom portion of the melt delivery tube has an internal shape to expand the external config...

In atomizing a body of molten material having elevated melting point by directing the molten body as a stream into an atomization zone and directing a stream of atomizing gas into said stream to atomize and disperse it, the orifice from which the gas is delivered is positioned closely proximate the surface of the stream to be atomized, e.g. less than 0.45 inches way. A large percentage of fine par...

The method of producing fine powder molten metal comprising providing a source of the molten metal to be atomized, delivering molten metal from said body to an atomization zone through a melt delivery tube, the portion of said delivery tube which is exposed to said atomization zone consisting essentially of boron nitride, directing a stream of atomizing gas against said stream in said zone to atom...

A method for generating prime powder from a material having a high melting point and apparatus for generating the powder is taught. The apparatus includes a melt delivery tube. The melt of the high melting material is introduced into the tube and exits from the tube into an atomization zone. Gas is delivered to the zone at high pressure as a stream to atomize the melt. Pursuant to the present inve...

A piston for actuating a brake-band end of a transmission band system includes a piston for actuating a band in a transmission. The piston includes a piston body, and an elongated guide shaft having a proximal end fixed to one side of the piston body and a distal end defining a first annular support surface. The guide shaft is formed to include an axial bore having an opening in the first annular ...

A cement additive comprising at least two fluidizing agents wherein one of the fluidizing agents is a saponified product of a sulfonated styrene-maleic acid copolymer and the other is one or more of a formalin condensate of naphthalenesulfonic acid and a polyoxyethylene-based compound. The cement additive of this invention is added to a cement composition (cement paste, mortar or concrete) and esp...
