  • Patent number: 7294804
    Abstract: Within a closing assembly that utilizes a ram assembly having a spring driven ram body, an energy dissipating spring seat assembly is provided. The ram body is mounted on a guide assembly having at least one pin. The guide assembly also includes a base plate and a stop plate. A ram assembly spring is disposed between the ram body and the base plate and is structured to bias the ram body toward the stop plate. The spring seat assembly includes a spring seat bracket and a spring seat. The spring seat is, preferably, a generally flat, plate-like leaf spring that is disposed between the ram assembly springs and the base plate of the ram body. The spring seat is sufficiently rigid so as to not deflect fully under the force created by the compressed ram assembly springs, but not so rigid as to resist deflecting under the force created when the ram body impacts the stop plate.

  • Patent number: 7265858
    Abstract: There is provided a method and system for initiating an information transmission, such as with faxing, e-mail, data streaming, or the like from a personal computer on a network having at least one networked multifunction machine. The method comprises the steps of invoking a fax command from a software program on a personal computer and then viewing a list of machines residing on the network which contain local address book information. Upon viewing the list, a machine is selected from the list and a search is conducted through the personal computer for a local copy of the selected machine's address book information. If no local copy exists, a local copy of the selected machine's address book information is created on the personal computer. The local copy of the selected machine's address book is then used to retrieve address book information for selecting a recipient of an information transmission.

  • Patent number: 7218192
    Abstract: A lockable fastener connects together a plurality of components of a circuit breaker and maintains electrical conductivity between the components while permitting relative movement therebetween. The lockable fastener includes a first clinch nut member and a second clinch bolt member. The clinch nut member includes a threaded cavity formed therein, a side having opening therein, and a passageway between the side at the opening and a surface proximate the threaded cavity. The clinch bolt member includes a threaded shank. At least a portion of the threaded shank is threadably receivable in the threaded cavity of the clinch nut member, in order to axially align the clinch nut and clinch bolt members. The clinch nut and clinch bolt members are adapted to be locked by deformation of the surface of the clinch nut member to prevent loosening of the members.

  • Publication number: 20060289140
    Abstract: A method for treating secondary fiber to achieve wet strength while retaining repulpability is provided. In an embodiment, the method involves supplying a first line of secondary fiber which represents a total supply of secondary fiber. The method has a further step of removing a portion of the total supply of secondary fiber in the first line and transporting the portion into a second line. The second line is treated with a cationic resin treatment. A third line supplies virgin fiber. The third line and the first line are combined. Next, the treated secondary fiber in the second line is combined with the mixed contents of the first line and third line. Separation of the virgin fiber line from the secondary fiber line at initial stages of the process lowers cationic demand for the system, and reduces an amount of resin required to treat the system.

  • Publication number: 20060289135
    Abstract: A sheet of cellulose based material having enhanced strength, particularly the dry strength, substantially unaffected repulpability is disclosed. The sheet of cellulose based materials generally includes a first cellulose based material connected with a second cellulose base material element. The first cellulose based material is formed by separating a portion of the fiber from a furnish, treating the separated portion with a cationic wet strength resin which is allowed to bond to the fiber. The treated fiber is them mixed with the untreated balance of the fiber at some point before the paper machine. The fiber that is separated may be secondary fiber, virgin fiber or combinations thereof. The second cellulose base material element is substantially free from any treatment. The second cellulose base material element may be include substantially all untreated fibers.

  • Publication number: 20060073329
    Abstract: Filler-enhanced polymeric fiber. High aspect ratio filler particles are placed into intimate contact during processing with a polymeric fiber. The filler particles serve as templates to orient the molecular structure of the polymeric fiber to enhance mechanical properties. The highly oriented molecular morphology results in enhanced axial stiffness and strength.
