Abstract:
A cylinder (10) for pressurised gas, the cylinder (10) being defined by a wall that is formed by deep drawing and being closed at one end and having an access valve at the opposite end, the access valve (16) comprising a valve stem (20) which is biased closed onto a seat by a biasing member (28) and is openable by being displaced against the biasing member (28). The wall defines an opening to receive the valve stem (20), and the valve stem (20) seats directly onto the part of the cylinder wall which surrounds the access valve (16). By seating the access valve (16) directly on the cylinder wall, this reduces the number of components needed in the valve (16), making the cylinder (10) cheaper to manufacture.

A cylinder (10) for pressurised gas, the cylinder (10) being defined by a wall and being closed at one end and having an access valve (16) at the opposite end, the access valve (16) comprising a valve stem (20) which is biased closed onto a seat by a biasing member (28) and is open able by being displaced against the biasing member (28). The cylinder wall is formed from first and second deep drawn shells (12;14). The first shell (12) comprises the one end and one part of acylindrical side wall which terminates at an open end. The second shell (14) receives the access valve (16), and forms the opposite end and the second part of the cylindrical side wall which terminates at an open end. The first and second shells (12;14)are joined at their open ends to form the complete cylinder.
Abstract:
A supply source for delivery of a CO-containing dopant gas composition is provided. The composition includes a controlled amount of a diluent gas mixture such as xenon and hydrogen, which are each provided at controlled volumetric ratios to ensure optimal carbon ion implantation performance. The composition can be packaged as a dopant gas kit consisting of a CO-containing supply source and a diluent mixture supply source. Alternatively, the composition can be pre-mixed and introduced from a single source that can be actuated in response to a sub-atmospheric condition achieved along the discharge flow path to allow a controlled flow of the dopant mixture from the interior volume of the device into an ion source apparatus.
Abstract:
A container for transporting and storing hazardous materials such as Chlorine includes a cylindrical body having end caps. The end caps are welded to the body to form a pressure vessel. The end caps have a peripheral edge that is recessed with respect to the ends of the body to protect the weld against damage from impact. The configuration of the juxtaposed components forms a lap joint that can be affixed together by a fillet weld.
