Abstract: A single handed oil filter puncher tool system and method that operates as an easy and simple time saving device for draining an oil filter during vehicle service with single hand operation. The system is a puncher tool assembly having a handle at a proximate end a perpendicular guide shaft. The tool further includes a sliding punch assembly and an outer sliding sleeve that work together in functional combination as a moving assembly that gets cocked into place while compressing a driving spring. An activation lever releases the sliding punch assembly from the cocked position causing the driving spring to unleash force on the sliding punch assembly. The sliding punch assembly slides along the guide shaft forcing a piercing pin into an oil filter in a single handed operation. The piercing pin punctures the oil filter causing it to drain.

Abstract: A method for slitting sheet material having a thickness, a width, a leading edge and a shear strength. The slitter has rotatable arbors and knives on each arbor that rotate about their axes and are held adjacent to each other. A computer is used to calculate a first and second spacing for the arbors based on the shear strength, outer diameter, and thickness of the material. The material is inserted between the knives and the leading edge passes through the slitter with the arbors the first position that pinches the material between outer diameters of opposing knives as it moves forward. While the material moves forward the arbors are moved into a second and closer position in which the knives are situated to slit the material as it passes between the knives. This slitting of material behind the leading edge creates a leading tab holding the slit strips together.

Abstract: This invention relates to an ampoule opening device (1) for the opening of glass ampoules (100) of the type used in particular in the pharmaceutical field for injection substances. The device according to this invention allows opening, by rupture of the neck of the ampoule, glass ampoules of different capacities (and therefore of sizes), by generating a non irregular rupture edge and therefore minimizing the creation of glass fragments that may fall into the substance contained within the ampoule. Moreover, the device object of this invention allows avoiding contact of the user's fingers with the neck and the cap of the ampoule, thereby preventing any risk of accidental injuries. The device object of this invention allows obtaining excellent results in terms of quality of the rupture edge of the ampoule neck and of repeating the result obtained thanks to the fact that the device allows to apply to the ampoule a constant rupture bending moment for ampoules of the same type.
