Abstract: A drum maintenance unit (drum maintenance unit) to reduce build up of electrostatic charge within a printer device. The drum maintenance unit may have a static shield positioned to reduce the build up of an electrostatic charge and to act as a physical barrier by preventing discarded oil from becoming airborne and returning to the oiling roller unfiltered. The static shield may also be utilized to retain and house the filtration system of the drum maintenance unit thus reducing part count and manufacturing time.

Abstract: A metering blade suspension system utilizes a leaf spring that performs multiple combined functions such as supporting a metering blade assembly, controlling the angle, position and/or load of the blade assembly while allowing the assembly to pivot in a quasi-frictionless motion, locking the blade assembly in place, providing an electrical connection and/or bleeding static charge.

Abstract: A latching mechanism is provided on a Drum Maintenance Unit (drum maintenance unit). The latching mechanism releasably secures the drum maintenance unit to a media device when installed in the media device and provides an electrical connection. The latching mechanism contacts with a locking tab and a data connection that may be located on a receiving portion of the media device. This arrangement allows the latching mechanism to simultaneously latch and connect with a receiving portion of the media device. The latching device of the connection device may be provided to releasably lock with the media device until a predetermined amount of force is applied.

Abstract: In a method of decalcification of purified sugar factory juices from a sugar factory process the juices, containing calcium ions, are sent onto an Na.sup.+ or K.sup.+ form strongly cationic ion exchange resin where the calcium ions are replaced with sodium and/or potassium ions. The ion exchange resin is then subject to regeneration (or washing) with dilute molasses. In a first variant of the method, the molasses is sent to the ion exchange resin in a cocurrent configuration. In a second variant, the molasses is sent to the ion exchange resin in a countercurrent configuration. This method can be used in a process to manufacture sugar from sugar beet or sugar cane.

Abstract: A process for the production of a panel, of the honeycomb support type clad on opposite sides with a skin of carbon/carbon or carbon/ceramic composite. A honeycomb support is produced by pyrolysis of a carbon cloth pre-impregnated with a thermosetting resin. Skins are produced from carbon cloth pre-impregnated with a thermosetting resin. The support and the skins are assembled with a carbon cloth pre-impregnated with a thermosetting resin between them. The assembly is polymerized and then pyrolyzed. Finally, a chemical infiltration in vapor phase is carried out for densification and reinforcement of the bonding of the assembly. Used in the production of structures requiring very high dimensional stability, such as those used in outer space.

Abstract: Aqueous sugar solutions are agitated in a batch process with strong cation exchange resin, optionally mixed with anion exchange resin, or with a mixture of weak acid cation exchange resin in the hydrogen form an anion exchange resin, under closely defined time and temperature conditions to effect decationization or deionization without the degree of cooling and dilution required in conventional fixed bed processes. In the presence of strong acid cation exchange resin the temperature is 20.degree. to 40.degree. C. and the contact time between sugar and resin is at most 20 minutes, unacceptable levels of inversion thereby being avoided. When weak acid resin is used as the cation exchange resin the temperature is 20.degree. to 90.degree. C. and the contact time is at most 90 minutes. When mixed anion and cation exchange resins are used color bodies are removed from the sugar solution.
