Abstract: An ink image producing machine has (a) imaging devices, including at least one ink jet print head and an image receiving station for producing an ink image on a heated substrate; (b) a substrate handling assembly including holding devices for holding supplies of substrates, and transport feeding devices for transporting and feeding substrates in a substrate direction towards the image receiving station; (c) a first substrate heating assembly located upstream of the image receiving station for initially heating each substrate being fed and transported from the holding devices; and (d) a second substrate heating assembly located downstream of the first substrate heating assembly and upstream of said image receiving station, relative to the substrate feeding direction, for controllably re-heating each substrate, initially heated by the first substrate heating assembly, to a desired ink image receiving temperature.

Abstract: A rotary power tool is provided having a remotely actuated chuck device. The chuck includes an outer sleeve member that is axially movable relative to the drive spindle between a gripping and release position. A sleeve actuating device is provided having a first member engaged with the outer sleeve member and which extends generally radially outward from the drive spindle or chuck. The first member is movable in a direction so as to move the outer sleeve member between the gripping position and release position. The sleeve actuating device includes an actuator member configured with the first member to move the first member upon an external force being applied thereto. The actuator member is generally perpendicular to the axis of the drive spindle and may be limited in length to be confined in the perimeter of the casing. In this manner, an operator can move the chuck device between the gripping release positions at a location remote from the chuck device and drive spindle.

Abstract: A rotary power tool incorporates a remotely actuated chuck device. An engagement surface, such as a threaded or helical surface, is defined on an outer circumference of the chuck device over an axial length thereof. An actuator member is disposed concentric and rotatable relative to the engagement surface. In an actuation mode, the actuation member is brought into engagement with the engagement surface so that rotation of the actuator member drives the chuck device axially between gripping and release positions.

Abstract: A rotary power tool has a remotely actuated chuck device. A hydraulic actuating system is incorporated in the power tool and is configured to move the chuck device between the gripping and release positions upon hydraulic fluid being supplied to at least one hydraulically driven actuator mounted relative to the tool casing and engaged with the chuck device to move the chuck between gripping and release positions.

Abstract: A rotary power tool is provided having a remotely actuated chuck device. The chuck is mounted onto the end of a drive spindle that extends from the casing of the power tool. The chuck includes an outer sleeve member that is axially movable relative to a drive spindle between a gripping and release position. A sleeve actuating device is provided having a first member engaged with the outer sleeve member and which extends generally radially outward from the drive spindle or chuck. The first member is movable in a direction so as to move the outer sleeve member between the gripping position and release position. The sleeve actuating device includes an actuator member configured with the first member to move the first member upon an external force being applied thereto. A base is rotatably advanceable and concentric on the casing. A helical opening is formed in the base.
