  • Publication number: 20230201997
    Abstract: A method of grinding a plurality of tufting blades of a blade assembly is disclosed. The plurality of tufting blades can be received within a blade block during grinding. The blade assembly can have a first axis, a second axis that is parallel to the first axis, and a third axis that is perpendicular to each of the first and second axes. Each tufting blade of the plurality of tufting blades can have a length that extends along the first axis, a width that extends along the second axis, and a thickness that extends along the third axis. The plurality of tufting blades can be spaced from each other along the third axis. The blade block can include at least one fastener that is configured to retain the plurality of tufting blades in respective fixed positions relative to the blade block.

  • Patent number: 9102247
    Abstract: A vehicle seat bar assembly having a seat with first and second engagement members. A rear seat bracket extends between the first and second engagement members of a seat. A torsion bar extends between the first and second engagement members and is operably engaged therewith. The torsion bar includes an intermediate bracket engagement portion and a first and second linear portion that extends between the first engagement member and the intermediate bracket engagement portion and the second engagement member and the intermediate bracket engagement portion. The torsion bar also includes a first and second distal end configured to engage the first and second engagement members, respectively, which induces a torsional resistance in the torsion bar when the seatback is at a fully reclined position and when the seatback is at a fully folded position.

  • Patent number: 6086397
    Abstract: A power strip is disclosed with an access panel which is situated and designed such that upon its removal, a sensor may be readily attached and the current load monitored. The access panel is arranged such that the receptacles, the power strip itself, or any of the electrical devices connected to the power strip do not need to be powered down to access the internal circuitry. The "back-wiring" design of the present invention allows for the replacement of any receptacle without interrupting the flow of electrical current to the remaining receptacles. The "back-wiring" design ensures the electrical load is evenly distributed across all the receptacles while providing a secondary path by which the electrical current may reach the receptacles. Thus, the disruption of electrical current across one wire will not result in the disruption of electrical current to any receptacle. Additionally, protective cover plates are utilized to prevent the unauthorized insertion of electrical cords into a power strip.
