Abstract: An additive suitable for use in a combustion fuel comprising:(a) a complex of an iron enolate having the formula: ##STR1## wherein R, R.sub.1 and R.sub.2 are, individually, hydrogen, alkyl having 1 to 22 carbon atoms or aryl in an amount effective to improve the combustion performance of the combustion fuel and, per part by weight of iron enolate;(b) 0.05 to 10 parts of a cerium enolate having the formula: ##STR2## wherein R, R.sub.1 and R.sub.2 are, individually, hydrogen, alkyl having 1 to 22 carbon atoms or aryl; and(c) 5 to 150 parts of a solvent capable of rendering the iron enolate and the cerium enolate miscible with the combustion fuel.

Abstract: An ink jet apparatus is disclosed which comprises a disposable ink reservoir and pumps for providing priming and purging to the ink jet and for providing subatmospheric pressure in the vicinity of the jet to collect any debris from the orifice of the jet prior to start up of the jet. In a preferred embodiment, both pumps are peristaltic and are powered by single motive means mounted permanently on a facsimile apparatus with which the disposable ink jet apparatus may be used.

Abstract: A catcher is associated with the nozzle of the jet. The catcher includes a chamber around the nozzle with an opening in the chamber for withdrawing ink and an opening for projecting droplets of ink therethrough.

Abstract: An improved deleaver for a continuous business forms assembly for separating the stationery plies and interleaved carbon plies from each other. The invention features a unique carbon turning bar assembly whereby the same is permanently affixed to the machine and yet may be moved between operative and inoperative positions, the latter being used when continuous business forms assemblies not having interleaved carbon are being processed. Also featured is a door in the wall of the first chute which may be selectively opened or closed. When extremely large forms are being processed such that they cannot rest generally parallel to the bottom of the first chute, the door may be opened to allow efficient processing.

Abstract: An improved deleaver for separating the plies of multiple-ply, continuous business forms stationery assemblies with or without interleaved carbon plies. The deleaver includes an input end and an output end having a plurality of ply-receiving pockets. Intermediate the output end and the input end is a first driving device for engaging the continuous business forms assembly along a path of stationery travel to drive the same from the input end to the output end. Located forwardly of the drive means is a pinfeed device for engaging the assembly and forwardly of the pinfeed assembly is an adjustable drag device. The pinfeed device includes a non-positive drive that tends to drive the stationery along the path faster than the rate at which the stationery is driven by the drive means and, due to the effect of the drag device, operates in bucking relation therewith to produce smooth deleaving at all points in a deleaving run.
