A containment pipe fitting has an inner member (), an outer member (), and a plurality of centralizers () positioning the inner member within the outer member. The fitting has at least one connection interface () having an internal surface portion () of the inner member sized to receive and join a portion of an associated inner/main pipe () and an internal surface portion () of the outer member sized to receive and join the portion of an associated outer/containment pipe (). The connection interface further includes an external surface portion of the outer member dimensioned to receive a closure coupling or collar (').

Containment pipe fittings and methods

A mold used to form a magnetic member includes a mold body having a mold opening, a mold support that supports the mold cavity, and a mold insert. The mold insert is disposed in the mold opening of the mold body to form a mold cavity. The mold insert is coated with a coating to protect the mold body from chemical attack and abrasive wear of the mold material. The coating comprises an electroless nickel layer formed on or over the mold insert, and a chromium nitride layer formed on or over the electroless nickel layer. The mold insert can be formed of beryllium-copper (Be&#x2014;Cu).

Composite coating for mold insert and method for making a coated mold insert

A method of manufacturing on a continuous basis quantities of seamed belts with imageable seams for printing systems from a continuous supply web of belt material, which seamed belts need to be manufactured to a desired circumference and width. In the disclosed embodiment the sides of the incoming supply web are cut in seam-forming mating edges and the web is fed in at an angle to a pair of rollers, at least one of which is tapered, to spirally wrap the web into a cylinder of the desired circumference of the seamed belts and providing mating engagement and gluing of the seam-forming edges. Then by sequentially transversely cutting off cylindrical segments of that spirally formed cylinder into the desired width, multiple seamed belts are formed with both the desired circumference and width.

Apparatus is provided for superpolishing the inside diameter surface of a seam of a flexible continuous photoreceptor belt. The apparatus includes (a) spaced apart support rollers for supporting the inside surface of the flexible continuous photoreceptor belt into a loop having strands, including a seam strand, between adjacent rollers; (b) a polishing machine mounted adjacent the seam strand, the polishing machine having: (i) polishing forms defining a path for the seam strand; (ii) a rotatable drum for supporting and carrying a polishing media material against the inside surface of the seam on the seam strand, (iii) sets of pinch rolls for clamping the seam strand and straddling the seam thereon; (iv) polishing media material mounted over the rotatable drum and through the path between the polishing forms for contacting the inside surface of the seam; and (v) a reciprocating superpolishing head for reciprocating relative to a width of the flexible continuous belt and a length of the seam, thereby simultaneously (x) reciprocating the superpolishing head in contact with the inside surface of the seam along the length thereof, (y) moving the seam with the sets of pinch rolls, and (z) rotating the drum for move the polishing media material in polishing contact with the inside surface of the seam and across a width of the seam to achieve required random superpolishing motion against the inside surface of the seam.

An imageable belt includes a seam that is finished using an abrasive finishing machine. The seam comprises a seam width with adhesive material disposed thereon. The finishing process includes an abrasive finishing media with a finishing surface and a backer bar. The backer bar comprises a backer bar radius. The backer bar surface is positioned against the belt inner surface so that the belt outer surface contacts the finishing surface to define a finishing contact arc with respect to the backer bar radius. A tension, feed rate and pressure are applied to the finishing media. Using the finishing machine, the seam is then finished to remove the adhesive material. The finishing process results in a seam that is imageable. In one embodiment, the backer bar radius is adjusted so that the finishing contact arc covers the seam width.

A mold used to form a magnetic member includes a mold body having a mold opening, a mold support that supports the mold cavity, and a mold insert. The mold insert is disposed in the mold opening of the mold body to form a mold cavity. The mold insert is coated with a coating to protect the mold body from chemical attack and abrasive wear of the mold material. The coating comprises an electroless nickel layer formed on or over the mold insert, and a chromium nitride layer formed on or over the electroless nickel layer. The mold insert can be formed of beryllium-copper (Be&mdash;Cu).

A magnetic catch assembly for securely holding a door or cover on a machine in a closed position. The assembly comprises a unitary, injection molded, plastic member at least one portion of the member being magnetized to form the magnetic catch and at least one portion of the molded unitary member forming a mounting bracket adapted to securely mount the magnetic catch assembly to the machine.
