Abstract: A diver-propulsion unit 1 has a two-part cylindrical casing 2,3 with hand-grips 9 either side for holding forwardly of the swimming diver and giving maneuverability. Propulsion-thrust is from a propeller 15 rotating within a cylindrical duct 14 of a nozzle-mount 11 to which the casing-parts 2,3 are clamped. The propeller 15 is driven via a belt-drive 25,26 by an electric motor 22 which is mounted on the nozzle-mount 11 outside the duct 14 and which is powered by batteries in externally-projecting pods 31 of the rear casing-part 3. The belt-drive 25,26 extends across the water-flow to the duct 14 within a channel 29 of the nozzle-mount 11. The channel 29 is closed by a radial cover-shell 6 of the front casing-part 2, and a fairing 30 of the casing-part 2 projects into a cylindrical rim 13 of the nozzle-mount 11 to establish a flow-path of reducing cross-sectional area into the duct 14.

Abstract: A liquid-pourer of molded plastics has a spout-portion (1, 17) with a spigot (7, 18) for insertion into a neck (11, 20) of a bottle (10, 19) for pouring liquid from it. Two complimentary segmental passageways (4, 5) extend lengthwise through the cylindrical spout-portion (1, 17) for discharge of liquid and admission of air to the bottle (10, 19) respectively. An elongate handle-portion (2, 24) extends both upwardly and rearwardly from the spout-portion (1, 17) to overlie the bottle (10, 19) to allow balance in holding it with the air passageway (5) above the pouring passageway (4). A ring (6) on the handle-portion (2) retains the cap of the bottle (10), and the spout-portion (1, 17) is attached to the bottle-neck (11, 20) by a screw-threaded collar (8), or a spring clip (15 FIG. 5).

Abstract: A holder for displaying a CD or DVD case (10) has a bowed configuration with regions (4) sloping up to a central, flat region (5) between a pair of opposed, hooked lugs (2). The back-face (11) of the case (10) rests on the region (5) between upturned lips (6) and the lugs (2) bear resiliently on opposite edges (13,14) of the case (10) to retain it firmly. Rocking of the case (10) frees the projecting rim (16) of the edge (13) from the hook-end (7) of the abutting lug (2). Alternative holders have a central spine (22;45) with laterally-extending legs (23,25;41,43) that terminate in hooked-lugs (24;42) or plain lugs (26;44), and have a wave-contour for back-support of the case (30).
