Machine for cracking a connecting rod having a small end and a big end, into a rod part and a cap part, the machine including positioning elements for positioning the connecting rod in a position for cracking, and an expandable element arranged to be inserted into a bore in said big end of the connecting rod so as to allow for splitting of the connecting rod into a rod part and a cap part by expanding the expandable element, where the machine further includes an electro press with a servomotor for actuating the expandable element.

A device for opening a sealed glass ampoule includes a housing that aligns the ampoule with a breaking mechanism. The breaking mechanism includes a sloped region that corresponds to the ampoule to be broken. After breakage of the ampoule, the ampoule head is stored in a storage area and can be removed later without the user having to touch the broken glass. The ampoule opener can be used with a mating base or on a countertop or other flat surface. The ampoule opener removes the need for the user to touch the ampoule during or after opening.

A method for fabricating a micromechanical part from a substrate in which the part is fabricated by providing a plurality of fasteners between the part and the substrate, the fasteners being sacrificial, characterized in that the fasteners include at least one hinge at the end of each fastener located beside the part, and in that the method includes a step of breaking the sacrificial fasteners. The micromechanical parts employing this type of sacrificial fastener are also described.

The machine for cracking a connecting rod comprises an electro press with an electric motor (400) for actuating an expandable element. The electro press comprises a first S actuator part (410) and a second actuator part (430) arranged so that when the first actuator part is driven by the electric motor (400) from a first position to a second position, (a) the first actuator part (410) is first driven by the electric motor (400) from said first position (FIG. 12A) to an intermediate position (FIG. 12B), without displacing the second actuator part (430), and (b) subsequently the first actuator part (410) is further driven by the electric motor (400) from said intermediate position (FIG. 12B) to said second position (FIG. 12C), displacing the second actuator part from a non-expanding position to an expanding position.

The present invention is a cast iron pipe cutter. The cast iron pipe cutter includes a movable upper cutting tool and a rigid lower cutting tool. The upper cutting tool and lower cutting tool includes multiple cutting disc spaced an arc length apart. As the upper cutting tool is advanced downward by a hydraulic press, the cutting discs apply increasing pressure to the outer surface of a cast iron pipe until each cutting discs in the upper cutting tool and the lower cutting tool creates a fracture in the cast iron pipe. The multiple fractures created by the cutting discs amalgamate into a single fracture and the cast iron pipe is cut almost instantaneously.

The disclosure discloses a blanking machine and a method for blanking a bar or pipe material. The blanking machine includes a blanking assembly and a plurality of driving members. The blanking assembly includes a housing, a plurality of pairs of slide rails, and a plurality of striking blocks. The housing defines a plurality of radially distributed grooves. The pairs of slide rails are respectively installed in the grooves. The striking blocks are respectively slidably installed on the pairs of slide rails. The driving members are configured to respectively drive the striking blocks to reciprocate along the slide rails to strike a material to be processed.

The various embodiments disclosed and pictured illustrate a hammer for comminuting various materials. The embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The hammer includes a connector end having a rod hole therein, a contact end for delivery of energy to the material to be comminuted, and a neck affixing the connector end to the contact end. The neck is formed with at least one neck recess therein. In other embodiments, one or more shoulders are positioned around the periphery of the rod hole for added strength. In still other embodiments, the contact end is configured with more than one contact surface.

A side trimming device according to an embodiment of the present invention may comprise: a cutting unit for mechanically cutting a transferred steel plate; a groove forming unit for forming a groove in a cutting-scheduled area in front of the cutting unit with reference to the steel plate transfer direction; and a washing unit arranged adjacent to the groove forming unit so as to suction molten material accumulating in the groove in the side direction of the steel plate.

The profiled metal fibre with a substantially rectangular cross-section, also with bent fibre ends in the form of a clip, is used to stabilise, bond, attach or join materials and construction materials such as concrete, wood, paper and the like. The fibre edges of the fibre outer surfaces extending in the longitudinal direction of the fibre are designed as edge surfaces (2) oriented at an angle to the fibre outer surfaces in the manner of a bevel. The two wider fibre outer surfaces (3.1, 3.2) of the rectangular fibre are provided with V-shaped channels (4) extending in the longitudinal direction, wherein the edge surfaces (2) are provided with projections (6) and the V-shaped channels (4) are provided with end zones (5) that bound their longitudinal extent. The projections form anchoring heads and the end zones form anchor surfaces with respect to the material to be stabilised, bonded or attached.
