Abstract: The present invention provides for an alignment device for aligning a punch tool to punch a design into a sheet media comprised of a clip, where the clip is comprised of first and second resilient arms meeting at a connection point. A first guide edge is disposed angularly from the first resilient arm, such that when the punch tool is secured in the clip between the first and second resilient arms and the sheet media is placed along the first guide edge, the punch tool is positioned to punch a design into the sheet media. Additionally, a second guide edge may be disposed angularly from the second resilient arm, such that when the punch tool is secured in the clip between the first and second resilient arms and the sheet media is placed along the first and second guide edges, the punch tool is positioned to punch a design into the sheet media.

Abstract: A cutting device has a body, a driving device, a moving base, a head and a cutting rod. The driving device is mounted on the body to actuate the moving base to move relative to the body. The head extends from the body and has a central hole defined through the head. A notch and an exhaust hole are defined in the bottom of the head and communicate with the central hole. The cutting rod is moveably received in the central hole in the head and is attached to the moving base. The cutting rod has a cutting recess defined around the cutting rod. Accordingly, the metal waste generated during the cutting process is kept from flying about and injuring the user, so the safety of using the cutting device is improved. In addition, the cut metal sheet can be kept from shake or vibration.

Abstract: A miter saw is provided having a support arm that is pivotally mounted to a base for adjustment of a pivot angle, the saw including a detent mechanism to provide pivot stops at common bevel angles, such as at 45° L, 0° (vertical), and 45° R. The detent mechanism includes a step-shaped, arcuate detent block mounted to the support arm in an adjustable manner to permit the accurate setting of the block in a home position. In an embodiment, a pair of set screws acts against opposite ends of the detent block, permitting precise adjustment in either direction. An axially movable detent pin is mounted to the base to contact against stepped surfaces of the block. The arm is free to pivot within a bevel angle range defined by one of the surfaces. Steps between surfaces act as a pivot stops, abutting the pin at a corresponding predetermined angle of the arm.

Abstract: A foil-cutting device is disclosed for opening a foil protecting a dose of medical power carried by a dosing cassette or the like for an inhaler device. The dosing cassette will in a typical embodiment carry a number of prepared doses (31), which for protection of the medical powder are covered by a metallic or plastic foil (24). The foil-cutter device of the present invention provides a tool (11) for accessing a selected sealed dose of medical powder of the cassette during an inhalation process using a dry powder inhaler (DPI). When a user inhales through the DPI the foil-cutter opens the foil (24) for access to a pre-metered powder dose (31). The foil-cutter arrangement ensures that no access is permitted to the pre-metered dose during any other circumstances. Particularly the present invention is adapted to be applied in an inventive continuous inhaler prolonging the release of a powder dose during the inhalation of the medical powder.
