Abstract: A method of evaluating the integrity of a substrate used in medical device packaging include providing a flexible, porous substrate having a first major surface, and a second major surface, applying a UV absorbent layer over at least one of the first and second major surfaces of the substrate, and placing the substrate over a UV reflective surface. The method includes directing UV light toward the substrate and the UV reflective surface, whereby the UV absorbent layer absorbs light in a spectrum that matches the wavelength of the UV light, and detecting with a UV sensitive camera any UV light that is reflected from the first and second surfaces of the substrate. The substrate is rejected if the reflected UV light that is detected by the UV sensitive camera indicates that the substrate has at least one opening having a size that is greater than or equal to 10 microns.

Abstract: The apparatus comprises a compositing bin (10), which may be constructed from modular elements (13), provided with a perforated or slatted floor (14) of a bedding frame (11) incorporated over the bin (10). The frame (11) is covered by a pyramidal roof structure (12), of translucent plastics panels, these can be connected into pairs by flexible tapes (18), the other edges being connected by tapes (19) incorporating sliding clasp fasteners (20). The bottom edges of the panels may be provided on their inner sides with channels (17) to trap condensation, and the edges of the panels may be reinforced by rods or dowels (22) in tunnel seams in the tapes (18, 19).

Abstract: A structural system comprises a set of elements including two or more plank members 10, which are preferably hollow and divided by interior partitions 12 into longitudinally extending compartments 13. The plank members 10 are open at each end, and are interconnected by connectors 20, comprising a stem 21, and two arrays of projections which may be aligned for in-line connection of the plank members, or set of right angles to form a corner, or have three arrays to provide a T-connection. The plank members 10 are connected vertically by rods 26 which pass through aligned apertures 14 in the plank members and notches 25 in the projections.
