2102320 9219382 PCTABS00017 An adapter for a centrifuge tube (T) comprises two segments (124)(144) that may be hinged along a hinge axis that extends perpendicular to the axis of the adapter.

In fluid catalytic cracking of oils, the feedstock oil is atomized so that its average particle size relative to the average catalyst particle size is such that most oil particles contacting a catalyst particle will form a film having a thickness substantially less than the boundary layer thickness of the thermal conduction interface between the feedstock oil and the catalyst. A nozzle suitable fo...

Polymer is recovered by ultrafiltration from a whitewater waste stream generated during the production of a polymer latex. The whitewater stream is circulated through an ultrafiltration system in laminar flow, under conditions of shear insufficient to destabilize the whitewater emulsion, and the recovered polymer is in the form of an emulsion which may be blended at significant levels into the ori...

A prefilled syringe is disclosed which comprises a syringe body with a slidable piston defining a compartment therein containing a substance to be injected. An injection needle is arranged for communicating with said compartment through said piston and sleeve means are provided around the needle in slidable relationship with said syringe body. A compression spring is urging the sleeve means in a p...

A pizza box (10) is described for microwave heating of frozen pizza for consumption. The box includes a lower tray portion (14) which receives the pizza (12), an upper lid portion (16) which encloses the tray and an integral wall portion (18) hingedly joining the upper lid portion and lower tray portion. A continuous electroconductive metal layer (56) having a thickness which is normally microwave...

The process of the invention relates to a process for the preparation of a ganglioside mixture, free from contaminants associated with non-conventional, life-threatening viruses, without altering the biological and pharmacological characteristics of the mixture on the central and peripheral nervous systems.

Self-supporting bodies are produced by reactive infiltration of a parent metal (10) into boron carbide (12) typically resulting in a composite comprising a boron-containing compound and metal. The mass to be infiltrated may contain one or more inert fillers admixed with the boron carbide (12), or at least one carbon donor material, to produce a composite by reactive infiltration, which composite c...

In a process of dressing a refractory structure, a comburent gas stream carrying a mixture of particles is projected against the site to be dressed. The particle mixture comprises particles of one or more elements which is or are oxidizable to form one or more refractory oxides ("fuel particles") together with refractory oxide particles and the fuel particles are caused or allowed to burn during p...

A water purification device with an inlet funnel (1), a sleeve (2) connected in a leak-tight manner to the funnel and an insert (3) which features approximately cylindrical side-walls (4), a sieve cover (5) and a sieve base (6) into which a granular detergent may be introduced. In order that collecting air or gases, for example, does not interfere with the flow of water requiring purification...
