A closed-cycle gas turbine chemical processor separates the functions of combustion air and dilution fluid in a gas turbine combustor. The output of the turbine stage of the gas turbine is cooled and recirculated to its compressor from where a proportion is fed to a dilution portion of its combustor and the remainder is fed to a chemical recovery system wherein at least carbon dioxide is recovered...

A structure of a joint of spun yarns formed by lapping the tops of two yarn ends in the untwisted state and jetting a compressed fluid to the lapped portion while keeping the tops of the yarn ends free without securing the tops of the yarn ends. In at least one portion of the joint, fibers of the two yarn ends are integrated to form one yarn having twists of the same or opposite twisting direction...

This invention relates to a sterilized intravenous pharmaceutical container (12), and more particularly to a sterile flexible plastic seal (10) for resealing a pharmaceutical container (12) and for leaving a telltale mark (30, 32) on the container (12) when the replacement seal is removed. The flexible plastic cover (10) comprises a flexible plastic material forming a layer (40) substantially impe...

An arrangement for mounting and feeding bead cores (in tyre production) has guides held at uniform intervals round the circumference of a circle to take the cores; it has endless chains carrying features to move the cores on those guides as the chains move, and it also has a threaded rod equidistant from and parallel to the guides to carry a collar which is connected to a chain. The guides are h...

In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's r...

A self-emulsifiable resin powder can be dispersed in water without utilizing additional surfactants or expending large amounts of mechanical energy. Such self-emulsifiable resin powders offer numerous distinct advantages over conventional latices. One of the most important benefits that is realized by utilizing self-emulsifiable resin powders is that they can be shipped dry which is the equivalent...

A torsional vibration absorber device is positioned between two relatively rotatable members.
