Abstract: A brush seal cover assembly that includes a brush cover having a shroud that substantially encloses a brush mounted in a holder without removing the holder from the equipment to which it is mounted. The assembly includes a pair of brush cover halves integrally formed to provide an outer bristle guard capable of supporting the weight of a person and a pair of brush shields on opposite sides of the brush that prevent direct impingement of pressurized gas or liquid enabling maintenance and cleaning of the equipment to be performed while leaving the brush mounted in place without damaging the brush. The cover includes a pair of mounting plates configured for mounting of the cover by clamping or by compression between fasteners without having to remove the brush holder from the equipment or the brush from the holder.

Abstract: A quick change brush holder of a brush seal having a plurality of spaced apart deflectable brush retaining arrangements that include a tab that is bent into a brush receiving channel toward a brush engaging or retaining position to releasably retain a brush in the channel and that is bent away from the brush engaging or retaining position when it is desired to remove the brush or install a brush in the holder. Each tab has a brush abutment edge that abuts or stops a shoulder of a tape or spine of a brush in the channel preventing removal from the holder when disposed in a brush engaging or retaining position. The brush abutting edge extends generally parallel to the channel enabling a brush to be inserted transversely relative to a lengthwise extent of the holder tape or spine first into the holder.

Abstract: A railway track barrier system that includes a barrier extending along a rail adjacent a switch having an upper edge adjacent a rail head disposed within a wash zone thereof formed of deflector elements movable relative to one another permitting railway vehicle wheel and wash contact during train passage without barrier dislodgement or damage. The barrier is formed of a deflector acutely inclined toward the head and a downwardly extending skirt that conforms to uneven railway bed and tie surfaces. A preferred barrier is formed of oppositely extending brushes removably attached to a mounting bracket. The bracket can be attached to a hinge assembly that releasably latches the barrier in an operating position and that can be unlatched permitting the barrier to be swung away from the rail to an inspection position. A hinge pin with a manually graspable handle can be removed to detach the barrier for storage.

Abstract: An injection molded disposable honing tool is made by an injection molding process. The tool has an elongated rectangular base from which projects an elongated section which may be somewhat smaller. The elongated section terminates in a working face. The entire tool may incorporate abrasive therein homogeneously or simply the elongated section which terminates in the working face. A shot of a plastic melt such as nylon is formed with abrasive mixed homogeneously which is then injected into a mold. For higher cost abrasive, a two shot process may be used with one shot being abrasive free. Alternatively, an abrasive-free insert may be placed in the mold before the abrasive mix is injected. The surface of the working face may be formed to act as a working face of closely packed fingers by placing patterns in the mold surface forming the working face, or subsequently cutting the working face, or a combination of both.

Abstract: A filter is provided. The filter includes a first layer of a non-blocking screen and a second layer of the non-blocking screen disposed against and in direct contact with the first layer, said first and second layers together forming a filter.

Abstract: An end brush and a method of making the brush is disclosed using the automatic distribution and insertion of the bristle fill material into the cup of a cup-shape shank holder. A centered drive stem projects from the bottom of the holder. After a measured amount of the fill material is inserted through fill tubes and a guide funnel, a centering core insert is forced into the center of the cup to distribute the fill material around and against the interior wall of the cup. The material is cut to proper length and in the same or a separate station the exterior wall of the cup of the holder is deformed or crimped inwardly girdling the core securing and centering the core and material in the holder. Axial ribs are also formed which improves transfer of heat from the holder improving tool life. Preferably the insert is softer than the fill material and may also be softer than the holder. A wide variety of fill materials may be employed as well as various shapes of inserts and holders.

Abstract: An elongated narrow and rather thin honing tool is made from a somewhat soft metal or plastic cup holder. A tightly packed bundle of abrasive containing plastic monofilaments is inserted to the bottom of the cup holder and the cup rim is swaged inwardly to girdle and grip the bundle holding the bundle in the cup holder. The projecting tightly packed tips of the monofilaments form the working face of the honing tool. The preferred plastic for the monofilaments is nylon and the preferred transverse sectional shape of such monofilaments is rectangular, although other plastics and shapes may be used. Several methods for forming the tool are disclosed which include an insertion step followed by a swaging step. The bottom of the cup may be slightly arcuate to impart a curved working face to the bundle. The bundle may be cut or trimmed before or after insertion.

Abstract: A plastic strap or tape having granular abrasive embedded homogeneously throughout is cut, shaped and formed into a variety of abrasive finishing tools. The plastic working element is preferably rather stiff 6/12 nylon and contains about 30 to 45% by weight of abrasive material. The strap or tape is formed by extrusion of such non-elastomeric plastic through a ceramic die opening and as extruded has an indefinite length in the machine direction, a controlled uniform thickness, and a width which is approximately 5 to 50 times or more the thickness. A preferred width to thickness ratio is about 30:1, or about 3 cm to 1 mm. The strap or tape may be cut to the desired length and partially embossed, serrated or scored either lengthwise or transversely to provide fracture or flex lines. The spacing of the serrations or score lines control the degree of flexibility or aggressiveness of the tool working face.
