A method and apparatus for producing high purity argon by combined cryogenic distillation and adsorption technologies is disclosed. Crude argon from a distillation column or a so-called argon column is passed to a system of adsorption vessels for further purification. Depressurization gas from adsorption is introduced back, in a controlled manner, to the distillation column and / or a compressor or other means for increasing pressure. Particulate filtration and getter purification may optionally be used.

Disclosed herein is a golf club including a shaft, a club head and several devices for releasably connecting the shaft to the club head.

A variable orifice combustor unit 10 comprises an annular combustion chamber 12 extending about a central axis 14 and ending in a discharge nozzle 16. Charging of the chamber 12 takes place from combustion fuel and air supply chambers 18 and 20 via a fuel charging orifice array 22 and an air charging orifice array 24. The orifices 28.1, 28.2 of the orifice arrays 22, 24 are positioned and slanted at the same forward angle in the direction of the nozzle 16 to the effect of their central axes 38, 40 cutting along the longitudinal centre of the combustion chamber 12. The cross sectional sizes of the orifices 28 are adjustable by means of an orificed displaceably mounted cyndrically shaped covering body 44 for the fuel charging side and an orificed cylindrical body 58 for the air charging side both being displaceable in the direction of the axis 12.

Embodiments of a magnetostrictive device, a dental lighting system, a method of illuminating a lighting apparatus and a lighting apparatus are disclosed. The embodiments may include a lighting apparatus with a light source, an electrical power storage device and a switch. When the switch detects a magnetic field, the switch may complete an electrical connection between the electrical power storage device and the switch, thus illuminating the light source. The magnetic field may be magnetostrictively or non-magnetostrictively generated, and maybe be produced by a receptacle, a hand-piece or the lighting apparatus itself. A user may switch the light source on and off. In a magnetostrictive device, the light may be illuminated even when a tip is not activated, and the electrical power storage device may be inductively re-charged. The lighting apparatus may be included in an insert of a magnetostrictive device, such as a magnetostrictive ultrasonic hand-held dental device.

The present invention provides a resist development processor consisting of a development processing chamber for storing a resist substrate having an exposed resist on the substrate and for developing the exposed resist by means of a development solvent consisting of a supercritical fluid; and a supercritical fluid container for storing a supercritical fluid, where the supercritical fluid container is connected to the development processing chamber through a valve.

Provided is an ultraviolet-curable silicone composition including: (A) a non-terminal epoxy group-containing organopolysiloxane, (B) an organopolysiloxane containing epoxy groups at the two terminals of the molecular chain, and an onium salt photoinitiator capable of generating cations upon irradiation with ultraviolet light. The silicone composition of the present invention yields a cured film that exhibits excellent ultraviolet-curability and can be readily peeled from a pressure-sensitively adhesive material. In particular, the silicone composition yields a cured film that exhibits a tight release force relative to pressure-sensitive adhesives such as acrylic-based pressure-sensitive adhesives, and also exhibits minimal fluctuation in the release force.

A hydraulic hammer device for excavators comprising at least one ripper (1) and an energy accumulator (4); where the energy accumulator (4) is located on the longitudinal shaft of the ripper (1) and integrally connected to said ripper (1); and where said shaft is on that which attacks the ground between the retracted and deployed positions of the ripper (1) and which is characterized in that it comprises a cylinder (2) or two cylinders (2,3) integrally connected to the ripper (1) inside same.

A method of producing a base compound for a liquid fluoroelastomer which is unaffected by the storage state of the added silica powder, and yields minimal fluctuation in the viscosity between production lots. Specifically, a method of producing a base compound for a liquid fluoroelastomer containing:(A) a linear fluoropolyether compound having at least two alkenyl groups within each molecule and having a perfluoroalkyl ether structure within the main chain, and(B) a hydrophobic silica powder,the method including:(1) heating the component (A) under normal pressure at a temperature of 50 to 100 ° C.,(2) adding 20 to 60 parts by mass of the component (B) to 100 parts by mass of the component (A) that has been heated in step (1) while performing kneading to obtain a kneaded product, and(3) kneading the kneaded product obtained in step (2) at a temperature exceeding 100° C., either under conditions of heat and reduced pressure or under conditions of heat and pressure.
