Abstract: In a non-storage CRT display system having a reiteration memory wherein video information is received in a .rho..theta. coordinate system and displayed on an XY raster the input coordinates are transformed as received digitized video information is transferred from an input buffer to the reiteration memory so that information previously stored in .rho..theta. format in the input buffer is subsequently stored in an XY format in the reiteration memory. The coordinate transformation is accomplished by calculating, at the completion of the read-out for display of a given horizontal line of data, the X and .rho. addresses of the reiteration memory cells to be up-dated from the input buffer during read-out of the subsequent horizontal line of data read-out. When the calculated X and horizontal X addresses correspond the reiteration memory is up-dated with calculated .rho. values.

Abstract: An improved waste material handling system includes a plurality of waste food disposer units which are operable to disintegrate waste food materials to form a slurry. The system also includes a pulper unit which is operable to disintegrate solid waste materials, such as paper, cardboard boxes, plastic bags, etc., to form a slurry. The waste material slurry is conducted from the waste food disposer units and pulper unit to a press which extracts water from the slurry. To prevent the discharge of waste material slurry from an active one of the waste food disposer units to an inactive one of the waste food disposer units and/or the pulper unit, check valves are associated with each of the waste food disposer units and the pulper unit. A pump is also associated with each of the waste food disposer units and the pulper unit to promote a flow of slurry from the units to the press.
