Abstract: A tray riser is configured for retrofit in a printer feed tray. The riser includes a plate for supporting a stack of sheets in the tray. A stand is integrally formed with a bottom of the plate to position a front edge of the plate higher in elevation than a back edge of the plate. A retention tab is integrally formed with the plate for engaging a pre-existing feature in the tray to retain the riser in the tray.

Abstract: A printer guide clip is configured for retrofit in a paper tray of pre-existing commercially available printer for blocking corner curling of forms transported therethrough. The clip includes first and second side tabs integrally joined together by an arcuate cap extending between the top ends thereof. The first tab is configured for retention inside a pre-existing slot in the paper tray. An inclined ramp extends outwardly from the second tab inside the tray in the vicinity of the form corner for blocking curling thereof during use. The clip is readily attachable to the tray for use with laminated forms, and is easily removable therefrom when no longer needed.

Abstract: A slurry tray and a method for removing residual vinyl chloride monomer from a polyvinylchloride resin slurry with reduced discoloration of the polyvinylchloride resin is provided. The slurry tray preferably includes partitioned channels that cause the slurry to flow at a velocity that maintains solids contained with the slurry in a liquid suspension and weirs contains holes to allow solids trapped at the bottom of the weir to flow continuously downward to a bottom of the plate tower for removal from the tower. The method preferably includes supplying the slurry towards the top of the tower and a vapor towards the bottom of the tower. The slurry descends the tower, while the steam simultaneously ascends the tower, both through directional valves. The solids trapped upon the surface of the trays travel down the tower through the holes within the weirs for removal from the tower.
