摘要:
The invention provides a solvent mixture including n-propyl bromide, a mixture of low boiling solvents and, preferably, a defluxing and/or ionics removing additive and/or at least one saturated terpene. The invention also provides a method of cleaning an article (e.g., an electrical, plastic, or metal part) in a vapor degreaser using the solvent mixture. The solvent mixture of the invention is non-flammable, non-corrosive, and non-hazardous. In addition, it has a high solvency and a very low ozone depletion potential. Thus, using the solvent mixture of the invention, oil, grease, rosin flux, and other organic material can be readily removed from the article of interest in an environmentally safe manner.

Embodiments herein include an apparatus that can comprise any heating device, such as one having an outer surface adapted to contact items, such as sheets of print media, and a rotatable air outlet (vent, jet, blower, etc.) positioned next to the heating device. The air outlet can be, in one embodiment, part of a tube-shaped air pleneum. In some embodiments, the air outlet can comprise a slit, perforations, rows of jets, etc. and the air outlet can have a length at least as long as the width as the fuser. The rotatable air outlet can be positioned to blow air to remove the items from the heating device and can rotate from a first position to a different second position.

A sheet stacking tray system for stacking different sizes of copy sheets on a stack supporting tray to be fed upstream to a reproduction apparatus for printing, on which tray the stack is registered against a side registration edge. An upstanding stack rear edge guide is track mounted for movement at an angle to that side registration edge to provide a large repositioning movement in the upstream direction together with automatic lateral movement toward or away from that side registration edge, so as to engage the rear edge of a stack of larger sheets further from the registration edge, more centrally of the downstream edge of those sheets, and to engage smaller sheets closer to the registration edge and thus more towards their centers. Two independent upstanding stack side edge guides may be repositionable towards the registration edge independently of, and not overlapping, any position of the angulary moving rear edge guide. The rear edge guide may be linearly track mounted at approximately 18 degrees to the registration edge. All three stack edge guides may extend through and move along separate elongated apertures in the tray. The downstream edge guide may be repositionable substantially closer to the registration edge than the upstream side edge guide due to the angular track of the rear side guide.

The present invention provides a solvent mixture comprising n-propyl bromide, a mixture of terpenes and a mixture of low boiling solvents, and a method for cleaning an article (e.g., an electrical, plastic, and metal parts) in a vapor degreaser using the solvent mixture. The solvent mixture of the present invention is non-flammable, non-corrosive and non-hazardous. In addition, it has a high solvency and a very low ozone depleting potential. Thus, using the solvent mixture of the present invention, oil, grease, rosin flux and other organic material can be readily removed from the article of interest in an environmentally safe manner.

A dual path sheet feeder is disclosed including a bypass transport loop and a main transport loop for selectively delivering sheets from a sheet feeding module to either a printer processing module or to a finishing module, wherein a movable gate situated adjacent to the bypass transport loop is provided for directing sheets along a predetermined path of travel. The movable gate is selectively positionable between a first position for directing the sheets through the main transport loop to the processing module to produce copy sheets prior to delivering the copy sheets to the finishing module and a second position for directing the sheets through the bypass transport loop to deliver insert sheets directly to the finishing module, circumventing the processing module. The dual path sheet feeder is contemplated for use in conjunction with a high speed electrostatographic printing machine for providing flexible paper supply options without the additional burden of providing supplemental dedicated sheet feeding trays.

A rapid warm-up and cool-down pressure roll assembly is provided and includes (a) a rotatable pressure roll including a cylindrical sleeve having an outer surface, and an inner surface defining a hollow interior to the rotatable pressure roll; (b) a thermoelectric assembly sheet positioned within the hollow interior and having a first substrate facing the inner surface of the cylindrical sleeve, a second substrate, an electric current flow path therethrough, and electric current input and output terminals associated with the electric current flow path; and (c) an electric current input switching device connected to the electric current input and output terminals for enabling selective reversing of a direction of electric current flow through the electric current flow path, thereby reversing which of the first substrate and the second substrate of the thermoelectric assembly sheet is hot and which is cold, and therefore selectively enabling a rapid warm-up or rapid cool-down of the cylindrical sleeve of the pressure roll.
