Abstract: FIGS. 1-16D & 66A-92D disclose a large variety of methods of forming the headgear for use in combination with a breathing apparatus including a unitary plastic core within textile casings. In some configurations, the plastic core material penetrates or bursts-through the textile casing of the straps. Some configurations include over moulding, alignment posts, T-joints and joint housings with injection aperture. FIGS. 17-65 & 93A-94C disclose a large variety of different headgear arrangements including top strap, front strap, rear strap and pairs of straps extending from the mask above and below the ear to meet behind the ear. FIGS. 95-121B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop when the connector is disengaged with the mask assembly.

Abstract: A customizable purse has a main storage compartment. A covering is removably attached to an exterior surface of the main storage compartment. The covering has a predefined depth to form an additional storage area on the main storage compartment.

Abstract: An elongate fuel element sub-assembly for use in a liquid metal cooled fast breeder nuclear reactor is adapted at a base end region for plugging into core support means and at the upper free end there is inertia damping means to prevent excessive vibration.

Abstract: A fuel sub-assembly has an adjustable coolant flow gag. The gag comprises two relatively rotatable co-axial tubes having baffles defining longitudinal flow paths. The flow paths house flow restrictions of different size and there is a valve member movable by one of the tubes for selecting one of the passages for coolant flow.
