PCT No. PCT/AU88/00028 Sec. 371 Date Jun. 28, 1989 Sec. 102(e) Date Jun. 28, 1989 PCT Filed Jan. 15, 1988 PCT Pub. No. WO88/05340 PCT Pub. Date Jul. 28, 1988.A mill is used to break up ores or gravel in which gold particles are to be found. The mill comprises an outer casing in which an internal housing is located. Within the internal housing is a rotor which rotates at about 1000-15000 rpm. The r...

BCRF1 proteins, and expression vectors for producing them, are provided for treating conditions associated with excessive production of IFN- gamma . Compositions of the invention containing BCRF1 proteins are useful in treating a variety of disorders, including allergy, psoriasis, tissue rejection, and MHC-linked autoimmune diseases.

The present invention discloses a blood cleaning hollow fiber membrane characterized by comprising a hydrophobic porous hollow fiber membrane and having a hydrophilic thin layer formed at least on the inner surface of said hollow fiber membrane by the grafting of a hydrophilic compound through the agency of a gamma ray, a method for the cleaning blood and an apparatus therefor using the same.

A control system for a motor vehicle provided with a continuously variable transmission. The transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. When torque of an engine is rapidly increased, the line pressure is increased so as to prevent a belt of the pulley de...

A high power lamp (2) that may be either an electrodeless or arc lamp is disclosed. The lamp contains a fill of either selenium or sulfur and a small amount of rare gas (e.g. argon or xenon).

This invention relates to a foldable armchair incorporating adjustable backrest and footrest, in which the connecting elements which control orientation of the footrest are connected to the backrest by pivoting crank pins provided with bearing faces cooperating with stops on said backrest, so as to make a unidirectional angular connection which ensures modification of the orientation of the footre...

A urethane prepolymer composition is provided comprising (a) a terminal isocyanate group-containing urethane prepolymer derived from a polytetramethylene glycol having a specific molecular weight of 700 to 1500 and an aliphatic and/or alicyclic diisocyanate and (b) a terminal isocyanate group-containing urethane prepolymer derived from a polycaprolactone diol and/or polyol having a specific molecu...

PURPOSE:To easily detect small-size foreign matter with high accuracy, by blowing up the small-size foreign matter by a jet fluid to irradiate the same from the side surface with fanwise laser beam. CONSTITUTION:Small-size foreign matters 2 are blown upwardly from a container 1 by the air flow 4 from an air pipe 3. The laser beam 9a from a He-Ne laser 5 is expanded in its beam diameter by an expan...

PURPOSE:To realize a motion target imaging system (MTI) or Doppler imaging system good in clutter exclusivity, by providing a receiving amplifier, a phase shifter, a Doppler filter and a buffer memory. CONSTITUTION:The high frequency signal oscillated from a high frequency oscillator 1 is amplified by a transmitting signal generator 2 to be inputted to a transmitting beam former 3 and the input si...

A period of a correlation signal from a laser Doppler velocimeter is calculated from crossing points at which a correlation function crosses over a threshold level by clipping and digitizing a Doppler burst signal, thereby enabling an accurate and real time measurement to be made of a flow velocity, even in low SNR Doppler signals. Smoothing the waveform of a correlation signal further improves me...

This invention relates to an apparatus and method for making large area diamond films using a high temperature plasma reactor (4) with a plasma reactor stream flow controller (18) constructed of a non-carbonaceous refractory metal such as tungsten or rhenium where hydrocarbon injection is used. Such structures of this type generally allow large area diamond films to be created on a substrate in an...

An inorganic, aqueous molding composition is described which can be hardened at low temperatures into molded parts having a high flexural stress at break. The molding composition is produced from electrostatic precipitator ash of high-temperature coal-burning power plants, this ash containing 45-55% by weight of vitreous SiO2 in addition to Al2O3, or from calcined bauxite by reaction with an alkal...

The invention relates to a logging method and apparatus for investigating the geometrical characteristics of a borehole. The apparatus comprises an array of circumferentially spaced apart azimuthal current electrodes (Aazi) disposed on a sonde (21), and an annular current electrode (A) longitudinally spaced apart from the array of azimuthal electrodes. Currents (Ici) are emitted between the azimut...
