In a process of separating a liquid sample having phase portions of different densities by centrifugal separation, a phase separator container is employed. The phase separator container comprises a housing having concentric inner and outer cylindrical walls defining a longitudinal axis and a top wall and further a piston body constituting a bottom wall of the housing. The piston body defines toget...

A NON-CRACKLING, ANTISTATIC POLYURETHANE FILM WITH HIGH BREATHABILITY AND ITS USE A b s t r a c t A waterproof and, at the same time, breathable and antistatic film produced without a support by extrusion, the film having a DIN friction coefficient of less than 0.8 and consisting of thermoplastic polyurethane elastomer resins with a melt flow rate, as measured at 190.degree.C under a load of 10 kg...

The invention relates to an externally applicable, antiviral pharmaceutical composition accumulating in the skin for treating herpes infections, which composition comprises 0.2-5% by mass of 5-isopropyl-2'- beta -deoxyuridine admixed with carriers, diluents and/or other additives conventionally used in the production of pharmaceutical compositions for external use.

Disclosed is a method which combines catalytic cracking and olefin production using a coked catalytic cracking catalyst as a dehydrogenation cataly st to dehydrogenate an alkane feed stream and form an olefin rich product stream. The method uses a plug flow regeneration system to form the dehydrogenation catalyst and to fully reactivate deactivated cracking catalyst for reuse in the cracking react...

The invention relates to an engine comprising a structural association of cylinders (24) in a cylinder block (20), a cylinder head (21), exhaust passages (47), intake passages (28), a crankshaft (9), injection nozzles (35), surge tanks (31), oil pump means (87), a power transmission belt (54) and/or other devices to arrange for a compact engine preferable to be used with an outboard motor.

A process of repairing a refractory body, including the steps of a. introducing combustible particles into a first gas stream containing no more than 18% oxygen by volume; b. causing an oxygen-rich gas stream to flow through a particle entrainment zone into a reaction zone adjacent a refractory body to be repaired so as to produce an aspirating effect within the particle entrainment zone effective...

This invention povides a plastic shield to protect an edge of a hollow core of a roll of sheet material from abrasion caused by one or more securing lines extending through the core and fastened to a deck upon which the roll is carried. The shield bends over the edge and around the circumferential core for a distance sufficient to cover a portion of the edge otherwise exposed to the securing lines...

Underneath and integral with the conveyor (2) that feeds the rolls (R) horizontally to the machine, is a unit (20) that can be raised, into alignment with the roll feeding conveyor (1), and that turns said rolls through ninety degrees to deposit them in single file and vertically in straight horizontal channels (227) where the sets of rolls (R') are taken at the right moment by the pushing cross p...
