摘要:
This document provides methods and materials related to polypeptides present in a vaccinia virus (e.g., membrane proteins such as vaccinia virus B5R, L1R, A33R, or A27L polypeptides). For example, methods for generating a vaccine comprising one or more of vaccinia virus polypeptides disclosed herein for preventing or treating Orthopoxvirus infection are provided. In addition, kits related to the use of vaccinia polypeptides are provided.

摘要:
A mixing device and method wherein liquids are rotatingly mixed in a disposable plastic bag mounted in and outer receptacle. The bag is provided with extending portions which overlap the open top of the outer receptacle. The interior sidewalls of the outer receptacle are inwardly sloping defining a truncated conical interior. When the bag is filled with liquid to be mixed the bag conforms to the sidewalls and does not twist around a rotating mixing element disposed through the open tops of the bag and outer receptable for mixing the contents of the bag. The mixing element is centered in the bag by a cap-like cylindrical structure that engages the top of the outer receptacle.
摘要:
A method of removing liquid from a slurry of solid material in liquid in which the liquid is squeezed from the slurry by passing the slurry through a roll nip and, simultaneously with the squeezing and passing, the liquid squeezed from the slurry is blocked from flowing through the roll nip.Apparatus for removing liquid from a slurry of solid material in a liquid includes a plurality of liquid guides, disposed in a spaced-apart parallel relationship, being inclined away from and opening adjacent the roll nip.

A polyurethane foam can be made from waste cellulosic products such as papermill sludge, wood chips, wood particles, sawdust, waste paper or cardboard scraps. The polyurethane foam is made by reacting together a polyisocyanate, a catalyst, and a cellulosic material.
摘要:
A low reactive pressure flame-retardant polyurethane foam made by reacting together a polymeric isocyanate, a polyol, an aqueous solution of a carbohydrate, calcium acid phosphate, sodium aluminum sulfate, sodium bicarbonate, and a flame retardant. A blowing agent may be present.
摘要:
Polyurethane foams which may be rendered flame resistant by the addition of flame retardants are produced by reaction between a carbohydrate, a polyisocyanate and water in the presence of a suitable surfactant and polyurethane forming catalyst.

摘要:
An improved mixing device for mixing at least two of a plurality of pressurized liquids, the device consisting of hollow tubular member defined as having a longitudinal axis, one or two open ends and an interior wall member, one of the open ends having at least two cut-out portions generally symmetrically disposed about the axis, a segmental slot member generally radially disposed in the hollow tubular member between each of the cut-out portions for receiving a supporting projection in locking engagement therewith, and an envelope mounted on and extending about each of the cut-out portions for receiving and encompassing a conduit member terminating at and within each of the cut-out portions, each envelope being disposed, constructed and arranged for directing one of the plurality of pressurized liquids onto a proximate area of the interior wall means thereof. The wall is cleaned by turning off the fluid flow but the blades continue to be rotationally driven whereby the wall is wiped clean by the blades which push the residue out the tubular members.
