Abstract: An inflation device for an inflatable article comprises a housing for supporting a container of pressurized fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurized fluid, said container being contained within a protected casing which is secured non-releasably to the housing thereby to prevent removal of the pressurized container.

Abstract: An inflation device 10 for an inflatable article comprises a housing 11 for supporting a container 15 of pressurized fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurized fluid, said container being contained within a protected casing 20 which is secured non-releasably to the housing thereby to prevent removal of the pressurized container.

Abstract: An inflation device mechanism (10) for inflation of an inflatable article comprises a housing (11) for supporting a container (18) of pressurized fluid and a piercing device (16) displaceable from a retracted position to penetrate the container to release pressurized fluid, bias means (22) to move the piercing device to penetrate the container, and actuation means comprising co-operating latching elements (26, 30) which, in an engaged, latched configuration, retain the piercing device retracted, said actuation means being actuable by either a first (35) or a second (36) control member to allow the latching elements to disengage and permit the piercing device to penetrate the container under action of the bias means, the first control member (35) comprising a water sensitive member which surrounds the latching elements and has a strength sufficient normally to support the latching elements in the engaged configuration but to allow the elements to disengage when reduced in strength by exposure to water, and the

Abstract: An inflation device 10 for an inflatable article comprises a housing 11 for supporting a container 15 of pressurised fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurised fluid, said container being contained within a protected casing 20 which is secured non-releasably to the housing thereby to prevent removal of the pressurised container.

Abstract: A method for manufacturing an EUV lithography element mirror includes sagging a plate of a glass material to produce an EUV mirror blank; and polishing a top face of the EUV mirror blank to produce a polished EUV mirror. A method for manufacturing an EUV lithography element mirror includes grinding a top face of a piece of a glass material; sagging a plate of the glass material over the top face of the piece to produce an EUV mirror blank; and polishing a top face of the EUV mirror blank to produce an EUV polished mirror.
