The shredding elements (16) extending out from the shafts(7-12) are rods in flat parallelepiped form. Each two shredding elements running diametrally to the shaft are sections of one of the parallelepiped form rods. The shredding elements extending from the shafts, viewed in the longitudinal direction of the shafts, run in alignment to each other and form a single line, or preferably a right angle...

A method of concentrating oocysts of waterborne protozoan parasites from water potentially contaminated by dilute densities of the parasites is described. Potentially contaminated water is fed into the separation channel of a continuous separation channel centrifuge. The water is centrifuged for a period of time sufficient to collect the parasitic oocysts and cysts in the channel.

A method and apparatus for reducing corrosion on the interior and exterior of a fuel storage tank. A galvanic anode assembly is placed within the interior of or exterior to the fuel storage tank and is surrounded by a layer of hydrophilic gel. The hydrophilic gel absorbs water in the fuel storage tank, thus removing it from contact with the tank. The hydrophilic gel also absorbs metal ions produce...

The flame detection system uses a microprocessor with a fuzzy-controller for analysis of the radiation intensity variations resulting from the flame, with signals outside a defined frequency band identified as interference signals. The mean and limit frequencies of the detected radiation are determined, with detection of periodic and non-periodic signals, the periodic signals with a mean frequency...

Elastic ethylene polymers are disclosed which have processability similar to highly branched low density polyethylene (LDPE), but the strength and toughness of linear low density polyethylene (LLDPE). The polymers have processing indices (PI's) less than or equal to 70 percent of those of a comparative linear ethylene polymer and a critical shear rate at onset of surface melt fracture of at least ...

A fiber comprising a polymer filled with a material that imparts cut resistance to the fiber, is provided. The polymer may be a liquid crystalline polymer. Also provided is protective apparel containing the fiber, such as cut-resistant, safety gloves.

A method, using a public-key cryptosystem, for enabling a predetermined entity to monitor communications of users suspected of unlawful activities while protecting the privacy of law-abiding users, wherein each user is assigned a pair of matching secret and public keys. According to the method, each user's secret key is broken into shares. Then, each user provides a plurality of "trustees" pieces ...

The invention is a formulation that contains: (1) a low-viscosity epoxy resin; (2) a phenolic chain extender whose concentration is less that 0.6 equivalents phenolic hydroxyl group per equivalent of the low-viscosity epoxy resin; (3) a catalyst that promotes self-curing reactions between epoxy groups; (4) an inhibitor that inhibits the activity of the catalyst under "B-staging" conditions; (5) le...

Expandable styrene polymers containing graphite particles are prepared by polymerizing styrene in aqueous suspension in the presence of graphite particles and of two peroxides which decompose at different temperatures, by a process in which the peroxide decomposing at the lower temperature forms neither benzoyl nor benzyl radicals on decomposition.

A composite is produced by arranging several different materials, one of which is a material with oriented reinforcement, pre-impregnated with a resin and moulding at raised temp. for a time sufficient to harden the resin and ensure bonding between the components. The components, including the resin, are arranged at the same time, before raising the temp., i.e. the resin is not injected separately...
