Abstract: A coated substrate has a substrate and a coating system having one or more ceramic layers. At least a first layer of one of the one or more ceramic layers is a columnar layer having as-deposited columns and intercolumn gaps. The intercolumn gaps have a mean width at least one of: at least 4.0 micrometers; and at least 1.5% of a thickness of said first layer.

Abstract: A shoe holder for attaching a shoe to a dryer for preventing the tennis shoes from banging in the drum of the dryer while being dried. The shoe holder for attaching a shoe to a dryer includes a piece of material being adapted to fasten about a sole of a shoe; and also includes fastening members for fastening the piece of material about the sole of the shoe; and further includes dryer attachment members securely attached to the piece of material and being adapted to detachably attach to a drum of a dryer.

Abstract: A bowling apparatus including a first support adapted to cover at least a portion of at least one finger of a bowler; a second support adapted to cover at least a wrist of a hand of a bowler; and an adjustable support comprising one end connected to the first support and another end pivotally connected to the second support.

Abstract: A feed system for large copy sheets to feed such sheets through a copying machine, such as a white print, blue print or other copying machine, a computer printing machine, a pen plotter of other vector plotter, or raster plotter, or a printing machine. A supply roll is provided with copy sheets wound on the supply roll in an interleaved or overlapping array. A pair of support rollers form a cradle for freely supporting the supply roll, with at least one of the support rollers being driven. A printing roller grasps a copy sheet as the sheet is fed from the supply roll. A sensor stops the driven support roller and, in turn, the supply roll at a given time in a predetermined cycle whereby the printing roller can pull the fed sheet away from the supply roll and away from a succeeding overlapped sheet interleaved with the fed sheet.

Abstract: An apparatus for collecting and stacking in an inverted orientation large copy sheet discharged from the exit port of a whiteprint, blueprint or similar copying machine. A receptacle trough is provided for arresting and captivating the leading edges of the copy sheets as the sheets are discharged seriatim from the exit port of the machine. A stacking tray is disposed adjacent the receptacle trough for receiving the copy sheets inverted and in sequential order while the sheets remain captivated by the receptacle trough.

Abstract: An apparatus for stacking large copy sheets beneath a tabletop model whiteprint, blueprint or similar copying machine. A support structure spaces the copying machine above a subjacent support surface as a tabletop, floor or the like. A receptacle structure is disposed below and forwardly of the exit port of the machine for arresting the leading edges of the copy sheets as the sheets are discharged seriatim from the copying machine and for causing the sheets to bow rearwardly onto a stack in the stacking space beneath the machine. The apparatus can be provided in kit form for application to existing copying machines.

Abstract: A copying machine such as a diazotype copier which uses developing reagents which produce fumes is provided with an economical attachment for scavenging any fugitive gas traces and passing them through a treatment cartridge. A manifold mounted in the machine housing has an insert strip with air access openings which can be sized to suit the requirements of a particular copying machine. An air conduit hose has a snap connection with the manifold and with one end of a blower housing the other end of which is attachable to and readily detachable from a unitary disposable supply package which is floor supported and supports the blower housing. The supply package includes a supply of gas generating development material in one portion, and in the other, a gas treatment cartridge of inexpensive disposable character which is so constructed as to pass incoming air down through a central tube and then upwardly through a tube-surrounding space containing gas treatment material and then into the surrounding atmosphere.

Abstract: Developing apparatus for diazo copy sheets is provided wherein the development chamber is supplied with anhydrous ammonia gas drawn from the region above the liquid ammonia solution in a reservoir. The ammonia gas is withdrawn from the reservoir by a pump which moves it into the development chamber. Due to the gas inflow inspired by the pump, the gas mixture in the chamber is caused to migrate out of the chamber by a return conduit whose outlet end is positioned below the surface of the liquid in the reservoir. The copy sheet transport means is a roll which occupies a mouth formed in a wall of the development chamber, and means are provided for effectively sealing the chamber contact margins against the roller to prevent escape of gas therefrom. The development chamber is arranged to snap over the roller and to be largely supported and positioned thereby.
