Abstract: A testing apparatus for the detection of Legionella bacteria in a liquid sample includes a sample tray and a lid member. The sample tray defines a planar surface and a plurality of wells recessed relative to the planar surface and is formed from a permeable, transparent material that is non-toxic to Legionella bacteria. The lid member includes an adhesive layer configured to be sealed to the planar surface of the sample tray and formed from a first permeable material, a breathable film layer disposed directly about the adhesive layer and formed from a second, different permeable material, and a backing layer disposed directly about the breathable film layer.

Abstract: A free standing self contained device for bonding ultra thin metallic films, such as 0.001 inch beryllium foils. The device will regulate to a predetermined load for solid state bonding when heated to a bonding temperature. The device includes a load regulating feature, whereby the expansion stresses generated for bonding are regulated and self adjusting. The load regulator comprises a pair of friction isolators with a plurality of annealed copper members located therebetween. The device, with the load regulator, will adjust to and maintain a stress level needed to successfully and economically complete a leak tight bond without damaging thin foils or other delicate components.
