Abstract: A device and method for determining a filter element is approaching an end of life obtains vacuum data corresponding to a vacuum at a filter element, and concludes the filter element is approaching an end of life based on the vacuum data as it relates to time in service. The end of life of the filter element may be based on detection of a knee in a vacuum curve derived from the vacuum data, high and low vacuum measurements over a specific time period deviating from one another by more than a prescribed amount, or high and low vacuum curves derived from the vacuum data trending apart from one another by more than a prescribed amount.

Abstract: Various processes and methods are disclosed for incorporating polyvinyl alcohol additives into products. In one embodiment, polyvinyl alcohol particles are dissolved in a solvent without the use of external heat to form a polyvinyl alcohol solution for incorporation into a product. In an alternative embodiment, polyvinyl alcohol particles are directly incorporated into a starch-based adhesive composition. Through the processes of the present disclosure, solid polyvinyl alcohol particles can be delivered directly to a manufacturing facility where the product that incorporates the polyvinyl alcohol additive is being made or formulated. In this manner, since the polyvinyl alcohol particles are not predissolved, the costs associated with shipping and transporting the polyvinyl alcohol product are greatly reduced.

Abstract: The fan filter mounting frame is useful in installation of equipment in a cell of suspension grid systems when the equipment is passed through and is placed in a corner of the cell. The equipment is supported partially directly by the grid and partially indirectly by the grid through an adapting frame insert. The frame insert is connected between the equipment and the suspension grid system and may have two legs that meet at an apex, a first leg extending along a first grid rail and a second leg extending along an adjacent second grid rail. Each of the two legs also extends between its respective rail and the equipment, supporting the equipment on the respective suspension grid rails. Thus, the grid system may be in its design position or condition prior to and during placement and replacement of the equipment without disruption.

Abstract: A current collector comprises one or more Fibre Bragg Grating sensors mounted on or in the current collector. Such collector can be used in a system in which:—i) detector means in the collector indicates a current collector condition and/or damage signal at a predetermined level likely to cause damage to the overhead conductor; ii) locating means operatively connected to said detector means generate a signal indicating the location of the pantograph on the overhead conductor at which the current collector damage signal was generated. Such a system can monitor not only impact forces on the collector, but also contact force and collector temperature.

Abstract: A telescopic automotive side mirror including a mirror housing attached to a side of a vehicle. The mirror housing has a tubular mirror bracket and a mirror supported therein. The housing has a support tube positioned within and interconnected to a plurality of webbing supports. A hydraulic cylinder is interconnected to a first end of the bracket and within the support tube. The hydraulic cylinder has an exit port and a receiving coupler. A shaft is positioned within the hydraulic cylinder, with a portion projecting from the exit port. The shaft has a threaded proximal end and a threaded distal end secured within the mirror housing by a locking nut. Lastly, an air compressor is in the vehicle and has a supply tube extending through to the mirror bracket. The supply tube couples with the receiving coupler. The air compressor supplies air pressure to the shaft to move the shaft within the hydraulic cylinder, for movement of the mirror housing.

Abstract: Suspended ceiling structure for cleanroom comprising a pressurized plenum, the lower face thereof is defined by filter plates supported by a metallic structure having the shape of an horizontal grid, comprising extrusions (P1, P2, P3) crossing at a right angle, said extrusions (P1, P2, P3) having upper channels associated in such a manner that they form a continuous channel around each mesh of the grid and they form a support for a filter plate (13, 13'), said channels (15, 15') being filled with a material in which dips a peripheral support (14, 14') for said filter plate (13, 13') to assure the sealing between the plenum and the volume beneath the ceiling structure, characterized in that each extrusion (P1, P2, P3) comprises at least one horizontal lateral groove (3), upon its full length and having the shape of a slide (2) having at each end housings (4) provided to cooperate with fixation means (5, 6, 7) of a perpendicular extrusion, said fixation means (5, 6, 7,) cooperating also with said slide (2) faci
