摘要:
A coin processing machine comprises a housing for containing the coin processing device, a coin processing unit disposed within the housing for processing received coins of a plurality of denominations and discharging processed coins into a plurality of coin receptacles, and a coin receptacle station disposed within the housing for holding a plurality of coin receptacles. The coin receptacle station includes a plurality of individually moveable platforms each having at least one coin receptacle disposed thereon. Each moveable platform is moveable between a first position and a second position. Each moveable platform is disposed entirely within the housing for receiving coins in the at least one coin receptacle disposed thereon when in the first position, and each moveable platform extends out of the housing when in the second position.

A low load fuser member for heating and fusing high quality toner images onto an image carrying substrate is provided. The low load fuser member includes a soft, low durometer and thermally non-conductive first elastomeric material member for forming a relatively large fusing nip at a relatively low load; a second and thermally conductive elastomeric material forming an intermediate layer over the first elastomeric material member; and a toner image release layer formed over the intermediate layer for facilitating release of fused toner images.

A guide for leveling the flow of a coating from a nozzle onto a generally cylindrical substrate of a polymeric printing component in a printing machine is provided. The substrate is rotated about its longitudinal axis by a turning apparatus having a axially movable slide for mounting the nozzle to the slide. The coating is spirally applied to the substrate. The guide includes a member operably associated with the slide and moves with the slide. The member has a surface parallel to and slightly spaced from the periphery of the substrate so as to assist in evenly distributing the coating on the periphery of the substrate.

A wastewater flotation separation system is provided, which operates effectively with a minimum of maintenance. The apparatus includes a container (12) for holding wastewater, an inlet (14) located at a lower portion of the container, and an aerator (24) adjacent to the inlet for generating air bubbles that cling to waste particles to bring them to the water surface. A skimming apparatus (30) which skims particles off the surface of the wastewater into a sludge receiver (44) includes a beach device (42) with an inclined upper surface (40), and a belt device (34) that moves a series of scrapers (32) along the surface of the water and along the beach device into the sludge discharge. Each scraper includes a flap of resilient material which is bent as it scrapes along the inclined beach surface. The aerator includes an aerator chamber (16) substantially sealed from the rest of the container except at its top, with the wastewater inlet opening to the chamber so bubbles are applied along the upwardly-flowing stream of waste water that flows up along the box into the rest of the container. The aerator includes a rotor (80) with hollow blades coupled to an air tube, with the tips (104) of the blades having holes opening in a substantially circumferential direction to better distribute the air bubbles. Recirculation pipes (110, 112, 114) extend from locations at the bottom of the container to the bottom of the aerator chamber.
摘要:
There is described a method for producing a fuser member. The method includes obtaining a substrate and positioning a fluoroplastic sleeve around the substrate. The outer surface of the fluoroplastic sleeve is roughened to a surface roughness of between about 0.03 μm Ra and about 3 μm Ra. The outer surface is coated with a functional silicone oil.

A layered structure, which may be used as a fuser member, comprises a first layer containing silicone; a second layer containing a fluoropolymer; and between the first and second layers, an adhesive layer comprising an aminosilane adhesive. In the layered structure, the second layer may additionally contain at least one of a polyamide-imide or a polyamide. Alternatively, or in addition, the adhesive layer may additionally contain fluoropolymer and at least one of a polyamide-imide or a polyamide.

The present invention relates to an electrophotographic system, having a member which includes a surface layer and also may include a base layer. The surface layer is prepared from a surface layer composition which includes a fluoroelastomer and a boron nitride filler coupled with a silane.
摘要:
A sludge processor is provided which enables rapid disassembly and reassembly for changing between a sludge thickener configuration and a press configuration, and for enabling rapid disassembly for cleaning in the press configuration. The processor includes a frame with opposite sides and roller-holding bearing devices at the opposite sides for holding rollers about which a belt extends past a sludge dewatering region. The bearing devices can be arranged in a first configuration (FIG. 2) wherein the belt (12A) extends in an even path, and a second configuration (FIG. 1) wherein the belt extends in a tightly convoluted path so it and material thereon is squeezed between adjacent rollers. The bearing devices (50, FIG. 4) are releasably mounted to the frame sides to enable rapid conversion, and to enable rapid removal of the rollers for cleaning the processor when used in the second configuration. Each side of the frame includes a plate with a hole (60) having a narrow inner part (64) and a wider outer part (62). Each bearing device includes a block (52) with grooves (72, 74), the block fitting into the outer hole part and then sliding into the inner hole part, with the opposite walls of the inner hole part sliding into the grooves of the block. A clamp (82) can be attached to each block to press against the extreme outer side of the hole to hold the bearing device in position.
