Abstract: A method of assembling a baghouse bag filter tensioning assembly is provided. The assembly includes a compressible spring having a progressively increasing spring rate. The spring rate facilitates induction of a substantially constant spring tension over a range of pre-determined operating conditions. The method includes coupling the spring to a bag filter support frame and a bag filter. The method also includes compressing the spring into a pretensioned condition. The method further includes coupling a bag filter to a baghouse floor. The method also includes decompressing the spring such that a tension induced in the bag filter is substantially similar to the spring tension induced over a range of pre-determined operating conditions.

Abstract: Methods and apparatus for stabilizing an exposed fabric edge are described. In one example embodiment, a base material includes at least one edge. A light cured adhesive is applied over the base material edge.

Abstract: A protective cover material includes at least two layers including a textile layer with an air permeable, moisture-vapor-transmissive, expanded polytetrafluoroethylene membrane attached to the textile layer, the membrane treated to render it oleophobic.

Abstract: A dry testing method for glove (10) made with an air permeable, waterproof material (16). The stem (22) of a tee fitting (24) is connected to an air pump (20) source. A mouth (30) of the glove is tightly attached to one end (32) of the fitting so no air can escape through the mouth. An airflow meter (26) or air pressure gauge connects to another end (28) of the fitting. When the air pump is running, the glove inflates with air and a backpressure is created. The flow meter is read to determine the backpressure level in the inflated glove, the glove being accepted if the meter registers at least a predetermined value indicating the glove does not leak water, but the glove being rejected if the meter reading is less than the predetermined value.
