Title: Diagnostic method
Inventor: SCHERRER KLAUS
IPC: C12Q1/37
Filed: 1991-10-11
Abstract: Disclosed is a method useful in the differential diagnosis of colon cancer or HIV infection. Persons suffering from colon cancer or infected with HIV have increased levels of extracellular prosomes in their blood in comparison to the blood of persons not suffering from these diseases. The presence and quantity of these extracellular prosomes can be detected either with certain labelled anti-prosomal protein monoclonal antibodies or by measuring the amount of protease activity in an extracted portion of blood which would contain the extracellular prosomes. The results once obtained can be compared with a ''norm'' derived from a person not suffering from such diseases.

Inventor: IKURA MICHIO
IPC: C10G1/00
Filed: 1992-11-27
Abstract: One method of coprocessing coal and heavy oil uses iron sulphate as a catalyst precursor which, upon decomposition to elemental iron and subsequent transformation to pyrite/pyrotite, assists hydrogenation of the slurry and suppresses coke formation.  For high process performance the iron sulphate should be dispersed as finely as possible throughout the reactant mixture.  In the present invention, the iron sulfate is added in the form of an aqueous wash solution to coal agglomerates after separation of ash from the agglomerated coal.  As the agglomerates remain in a continuous water phase, a good dispersion of the iron sulfate solution throughout the agglomerate matrix occurs.  At this stage an unexpectedly strong adsorption of FeII ions onto the coal surfaces occurs without any adverse effects on agglomerate integrity and the ability to separate it selectively by floatation.  Furthermore, this good dispersion also results in over 94% of the iron sulfate in the wash solution being transferred to the agglomerates. This manner of addition of iron sulphate to coal has been shown to elevate advantageously the lowest temperature at which coke formation occurs during coprocessing.

Abstract: (57)Abstract An apparatus and method are disclosed for extruding a product which comprises a longitudinal component e.g. a tubular sheet and/or longitudinal filaments in a circular array, and transverse filaments which follow a helical path relative to the longitudinal component, whereby the product may consist of a lattice or a reinforced sheet material.  The trans-verse filaments are formed by cooperation between two die parts (101; 102) to which relative movement is imparted so that one part (102) per-forms a rocking motion progressing around a circular path to influence the extrusion orifice, without rotation of the die parts.  The extrusion ori-fice may comprise an annular slot defined between two die members (106; 108) of the first die part (101) which is held stationary, while the second die part (102) extends around the first part and has an edge for alternatively opening and at least partially closing the slot at each point along its annular extent in response to the relative circular rocking move-ment imparted to the second part (Fig.7). Alternatively, the extrusion ori-fice may be defined between cooperating frusto-spherical surfaces (4, 8) of the two die parts (3, 7) with the inner die part having a groove (9) which is alternately exposed and concealed due to circular rocking mo-tion imparted to this die part (Fig. 1).
