Abstract: The present invention relates to medical vacuum pump filtration devices configured to filter air being received by the pump. The filtration devices comprise a pump housing and a mounting cap which incorporates filtration capabilities that capture and or divert particulate matter and moisture away from a pump intake opening. The filtration cap can also include apertures for sensors contained within the vacuum pump housing and the filtration cap. Compliance features that ensure proper installation and use of the filtration device can be included.

Abstract: A door frame made of synthetic material having an elongated, horizontally-oriented head and an elongated, horizontally-oriented sill, spaced apart from the head portion. The head and sill are preferably single, continuous members. The door frame also has at least two spaced apart, vertically-oriented jambs, each connected at one end to the head and at an opposite end to the sill. The jambs have a cavity disposed vertically therethrough. A rigid supporting member is then provided within selected jamb cavities. The rigid supporting members are preferably made of metal, such as aluminum, aluminum alloys and ferrous and non-ferrous materials. The jambs may further have more than one cavity disposed vertically therethrough, so that more than one supporting member is provided in a jamb.

Abstract: An applicator for coating sheet material has a relatively thick compressible, saturable layer for engaging the sheet which is effective to apply an optically clear coating when saturated with a flood of liquid coating composition. The coated article has virtually no visible defects and has high optical transmission and low haze.

Abstract: An apparatus and method for controlling in a variably controllable fashion the width of an extruder die opening whereby the width of material being extruded may be controllably varied.

Abstract: A method for continuously producing corrugated sheet from a supply of material having low melt strength at the forming temperature includes a heater, a pair of interdigitated thermo-forming rollers for corrugating the sheet as it exits the heater and a closely coupled calibrator at the outlet end of the thermo-forming rollers. A carrier maintains lateral tension on the sheet as it is heated, thermo-formed and calibrated so as to maintain its uniform lateral width. The thermo-forming rollers and calibrator form and maintain the corrugations until the material cools to below the glass transition temperature. A method for producing the corrugations is likewise disclosed.

Abstract: A novel extrusion method and apparatus are disclosed for varying the width of an extruded article which employs the use of thermal pins in the extruder die body and does not involve the use of any mechanical manipulation of the die configuration.

Abstract: A multilayer structure which comprises a layer comprising a polybutylene terephthalate adjacent to a layer comprising an aromatic polyester selected from the group consisting of aromatic polycarbonate, copolyestercarbonate, polyarylate, or mixtures thereof.
