Abstract: A pod comprises a box-section steel frame (1) having horizontal structural members (4, 11). A floor is provided by welding a 6 mm steel plate (10) to the horizontal structural members (4, 11). The plate (10) has a checkered pattern of 2 mm ridges on its lower surface. A combination of inherent stiffness of the plate material, the ridges (50) and welding to both edge (4) and internal (11) structural members achieves sufficient stiffness of the floor to allow it to be tiled off-site during manufacture because the floor is thin, there is no need for the builder to provide a recess in the concrete on-site.

Abstract: A liquid dye preparation comprising an aqueous solution containing at least 0.5% by weight of a water-soluble anionic dye and at least 0.1% by weight of a surfactant of the formula: ##STR1## wherein R represents a non-ionic substituent,m represents an integer from 0 to 3,X represents a divalent bridging atom or group,Y represents a C.sub.2-4 alkylene radical,n represents an integer of at least 2, andZ represents hydrogen, akyl, sulpho or phosphino.
