Abstract: Staple fibres of solvent-spun cellulose are made by a method in which:i) cellulose is dissolved in an amine oxide solvent to form a hot cellulose solution,ii) the hot cellulose solution is extruded through a die assembly to form a tow of continuous filaments,iii) the tow is passed through a water bath to leach out the amine oxide,iv) the tow is crimped by passing through a stuffer box in which it is compressed to apply crimp,v) dry steam being injected into the stuffer box during the crimping process, andvi) the crimped tow is passed to a cutter and cut to the desired fibre length. An apparatus is also provided in which the staple fibres can be made.

Abstract: A guided missile for air to ground deployment having a modular construction which can be readily configured to suit varying deployment roles. The missile comprises a common central fuselage 1, 2, 3 carrying a fuel tank and mounting points for an engine, wings and nose-cone 7. Bolted onto either side of the fuselage are panniers 6a, 6b of variable length and payload capacity. In one embodiment the panniers 6a, 6b carry munitions for lateral ejection through frangile panels. In an alternative embodiment, munitions are mounted in the fuselage and the panniers carry fuel.

Abstract: A solar rocket absorber of rhenium tubes is used to provide heated liquid hydrogen to a thruster. The rhenium tubes are wrapped in a closed shape having an opening for receiving solar radiation for heating the liquid propellant. The vessel of rhenium tubes is held by a carbon shell which is further encased in a reradiation shield to prevent heat loss.

Abstract: A dual purpose tennis net tie down and height setting device 14 comprises a top hook 16 for attaching to the upper edge 18 of tennis net 12. Depending from the top hook 16 is tie down chain 20 which connects in parallel with bottom hook 26 and a height refinement turnbuckle 32. By joining bottom hook 26 and chain 20 in parallel, the bottom hook 26 may be adjusted to correct for deviations in the depth of tie down fitting 24 without altering the distance between top hook interior 22 and the bottom of the last chain link 30.

Abstract: There is provided a ceramic heat exchange module 10 having fluid inlet and outlet conduits (12,20) extending from one side of horizontal manifolds (14,18). Serpentine tubes 16 extend from the opposed sides and connect the manifolds. In use, in a fluidized bed combustor 22, the manifolds are positioned between the base 30 and air inlets 32. Serpentine tubes extend into the fluidized bed 36, the fluid inlet and outlet conduits extend through the base for coupling to a working fluid supply.

Abstract: There is provided a fluidized bed combustor comprising an economizer contained in an upper interior portion and indirect heat exchange conduits suspended in the lower interior portion of the fluidized bed combustor in spaced relation to the interior surfaces of the fluidized bed combustor.
