Abstract:

A cutting tool retention mechanism, for example, typically used to retain a tool holder in a tool pocket of a tool changer magazine. A horizontal machine tool apparatus typically contains a plurality of tool pockets attached to a movable tool changer magazine and the mechanism of the present inventions provides an affirmative mechanism for retaining tool holders so that they do not separate from their respective tool pockets unless removal is desired. More particularly, a pair of opposed pivotal fingers each include a latch which can engage with or disengage from the internal groove of a tool holder to perform this function. Spring bias can be provided to encourage this affirmative engagement of the latches with the internal groove.

Abstract:

An elongated open ended tube has a square or rectangular cross-section and light reflecting inner surfaces. The tube is formed with flat semi-rigid side walls flexibly connected at the corners for collapsing or folding the tube between a generally flat storage and shipping position and an expanded tubular position for installation. The tube extends within an attic of a building with its upper open end portion covered by a light transmitting skylight attached to the roof of the building and its lower open end portion covered by a light transmitting and diffusing panel or lens attached to a ceiling of the building.

US Classification:

52200, 52 22, 522208, 359150, 359591

Abstract:

A square skylight panel is vacuum-formed of light transmitting sheet plastic and has a lower peripheral flange which projects under roof shingles. The skylight panel covers a one-piece upper coupler member which is vacuum-formed of light transmitting sheet plastic and has an upper flange projecting under the skylight panel flange. A flexible and collapsible cylindrical tube has an upper end portion surrounding a lower wall portion of the upper coupler member and a lower end portion surrounding an upper wall portion of a similarly formed lower coupler member having a bottom flange received within a square frame attached to a ceiling and supporting a light diffusing ceiling panel. The skylight panel, upper and lower coupler members and ceiling panel define three dead air chambers providing for high thermal insulation, and the upper coupler member provides natural light into the attic between the roof and ceiling.

International Classification:

B23P 23/02

US Classification:

29 565

Abstract:

A machining center is designed for machining a hub having faces that are spaced one hundred and twenty degrees from one another around the hub. The machining center includes a table for supporting the hub when it is being machined and three vertical gantries arranged around the table that are spaced one hundred and twenty degrees from one another. The gantries have X and Z axis drives for moving the gantries parallel to the faces of the hub and toward and away from the hub. At least one machining member is mounted on each of the gantries for vertical movement on the gantry and stroke drives are provided for the machining members for driving the machining members toward the center axis of the hub, allowing the three faces of the hub to be machined simultaneously by the machining center.
