Abstract: A display card 5 for tools 1 having belt hooks 4 comprises a card 5 of foldable material. The card 5 is slotted so as to form a flap 2 and a tongue 6. The flap 2 is adapted to admit the belt hook 4 of the tool 1. The tongue 6 is adapted so as to be folded towards the flap 2. The tongue 6 is hingedly connected to the card 5, and comprises a tab 3 which is inverted when the tongue 1 is folded towards the flap 2.

Abstract: A fastener is a screw having a threaded shaft, and a fastening strip or sheet having a raised portion provided with an aperture being preformed to have an at least partly helical threadform-defining edge shaped and dimensional to matingly receive the threaded shaft of the screw. The crests of the threaded shaft have an asymmetrical surface profile in the axial direction of the threaded shaft which enables the shaft to withstand greater applied torque.

Abstract: A battery powered lamp includes a two-part rigid casing comprising a hollow body with an end cap removably attached to the body and a water impermeable sock of flexible resilient material designed to fully enclose the body and partially enclose the end cap. The sock includes an annular rib trapped between the body and its attached cap.

Abstract: Shaft seals of the lip type with a sealing member bonded to an apertured insert have a tendency to form blisters in the sealing member near the bond. In order to avoid this, and provide a seal suitable for use in hygienic environments, the sealing member is mechanically engaged with the insert, for example, by being in the general form of a grommet with a central boss filling in the aperture and carrying the sealing lips, and having a wide radial flange forming a cleanable face exposed to the process fluid and a narrow deformable flange adapted to pass through the aperture of the insert and to expand into mechanical engagement therewith.
