Abstract:

A method for making abrasive agglomerate particles from a composition comprising at least a radiation curable binder and solid particulates. The method comprises the steps of forcing the composition through a perforated substrate to form agglomerate precursor particles which then separate from the perforated substrate. Then, the particles are irradiated to form soldified, handleable agglomerate particles before being collected.

Abstract:

Methods for making ceramic aggregate particles comprising forming a plurality of ceramic aggregate precursor particles from a composition by forcing the composition through at least one orifice in a substrate, at least partially curing the ceramic aggregate precursor particles, and heating the ceramic aggregate precursor particles to provide ceramic aggregate particles wherein solid particulates are bonded together by ceramic binder. In another aspect, the present invention provides methods for making an abrasive article utilizing methods for making abrasive ceramic aggregate particles comprising forming a plurality of ceramic aggregate precursor particles by passing a composition through at least one orifice in a substrate, separating the abrasive ceramic aggregate precursor particles from the substrate, at least partially curing the abrasive ceramic aggregate precursor particles, heating the abrasive ceramic aggregate precursor particles to provide abrasive ceramic aggregate particles bonded together by ceramic binder, and combining at least a portion of the abrasive ceramic aggregate particles with abrasive article binder material and abrasive material, with or without another abrasive material, to provide an abrasive article.

International Classification:

A61B 17/29

Abstract:

A surgical device comprising: (a) a first jaw; (b) a second jaw opposing the first jaw, the first jaw, the second jaw, or both being movable relative to one another between a jaw nominal position and a jaw clamped position; (c) a clamp lever in communication with the first jaw and the second jaw, the clamp lever moving the first jaw, the second jaw, or both from the jaw nominal position to the jaw clamped position when an external force is imparted upon the clamp lever in a first direction; and (d) a stop bias member that stops movement of the clamp lever when the external force is removed so that the first jaw and the second jaw are in the jaw nominal position at rest; wherein the first jaw and the second jaw are movable from the jaw nominal position to a jaw spread position when the clamp lever is moved in a second direction that opposes the first direction by an external force deforming the stop bias member so that a distance between the first jaw and the second jaw is larger in the jaw spread position than in the jaw nominal position.

International Classification:

F41A 3/66
F41C 3/00

Abstract:

A pistol slide with a separable breech block includes a slide and a breech block. The breech block is configured to be secured within the slide such that one face of the breech block forms a breech face within the slide. The breech block and the slide may be made of materials with different density to reduce the weight of the pistol slide while ensuring mechanical compatibility of the pistol slide with various pistol bodies.
