摘要： A folding utility knife has a handle and a blade holder pivotally mounted on he handle. The blade holder is movable between (i) a closed position with the blade holder pivoted inwardly toward the handle, (ii) a cutting position with the blade holder pivoted outwardly relative to the handle, and (iii) a blade release position located between the closed position and the cutting position. A blade release actuator is located on the blade holder and is movable between (i) a first position preventing release of a utility knife blade located on the blade holder, and (ii) a second position permitting release of a utility knife blade located on the blade holder. A locking member is movable between (i) a blade locking position with the blade holder located in the cutting position that prevents movement of the blade release actuator from the first position to the second position, and (ii) a blade release position with the blade holder located in the blade release position that permits movement of the blade release actuator from the first position to the second position to, in turn, release a utility knife blade from the blade holder.

摘要： A system and method is featured for controlling a process parameter of a thermal processing system by estimating an arc voltage between a plasma arc torch tip and a metallic workpiece and controlling the process parameter based on the estimated arc voltage. Particular embodiments include adjusting the height of a plasma torch based on the estimated arc voltage. A system and method is also featured for estimating an arc voltage in a thermal processing system in which a switch mode power supply provides an arc current to generate a plasma arc between a plasma arc torch tip and a metallic workpiece.

摘要： A utility knife has a blade carrier defining a blade support surface movably mounted in a housing between retracted and extended positions. A catch is mounted on the blade carrier and is movable between a first position engagable with a blade seated on the blade carrier and substantially preventing the blade from moving relative to the blade carrier, and a second position spaced away from the blade located on the blade carrier and permitting removal of the blade from the blade carrier. An actuator is mounted on the blade carrier and is operable to move the blade carrier between the retracted and extended positions to, in turn, move a blade located on the blade carrier between retracted and extended positions, and move the catch between the firs and second positions to release a blade from the blade carrier. The housing has a nose portion that defines the blade aperture and is made of a more wear-resistant material than the other portions of the housing. A sheet material spare blade holder is mounted within the housing and defines a fold, a support portion located on one side of the fold, and a biased retaining portion located on the other side of the fold for receiving spare blades therebetween.

摘要： A handle for a utility knife includes a housing made up of two or more portions. In one embodiment, a manually operable member for use in releasing the blade is retained to at least one portion of the housing and does not become separated from the housing when the housing is in an open state. In another embodiment, a catch for engaging the blade extends from a support member that is slidably movable within the housing. In another embodiment, the housing is formed of metal and a nose portion is formed of a metal that is more wear resistant than the rest of the housing, in order to improve the durability of the nose portion. In another embodiment, a bail screw is captured on a first housing portion and threadedly engageable with a second housing portion for (i) releasably securing the first and second housing portions in a fully closed state and, in turn, releasably securing a blade within the blade opening, and (ii) manually positioning at least one of the first and second housing portions in at least one intermediate state between the fully closed state and a fully opened state to, in turn, permit the blade to be manually moved through the blade opening.

摘要： A handle (62) for a utility knife (60) includes a housing (70) made up of two or more portions (76, 78). In one embodiment, a manually operable member (74) for use in releasing the blade (64) is retained to at least one portion of the housing (70) and does not become separated from the housing (70) when the housing (70) is in an open state. In another embodiment, a catch (362) for engaging the blade (64) extends from a support member (360) that is slidably movable within the housing (70). In another embodiment, the housing (70) is formed of metal and a nose portion (80) is formed of metal that is more wear resistant than the rest of the housing (70). In another embodiment, a bail screw (395) is captured on a first housing portion (376) and threadedly engageable with a second housing portion (378).
