摘要： An apparatus is described for producing concave or convex optically magnified facets about a gem, each facet being a curved surface that is a section of a cylinder. It utilizes a mandrel having an exterior and/or interior cylindrical abrasive surface. The surface is contacted by a gem indexed and adjustably held by a gem support structure. The mandrel is angularly movable about its central axis. It can also be reciprocated along the axis to prevent formation of random striations across the facet surfaces. An adjustable stabilizer can be preset to engage a dop attached to a gem at a location adjacent to the mandrel. This assures accurate reengagement of the gem after movement from the mandrel for interium inspections during the faceting precedure. The method of producing the optically magnified facets requires successive indexing of the gem and bringing it into contact with an angularly moving cylindrical abrasive surface. The resulting gem can have one or more curved facets about its outer surfaces having the form of a section of a cylinder. These facet surfaces can be either concave or convex. A preselected pattern of grooved facets can be produced across the curved facets by polishing then against a complementary moving mandrel surface.
摘要翻译：描述了一种用于产生围绕宝石的凹或凸光学放大小面的装置，每个小面是圆柱体的一部分的曲面。它使用具有外部和/或内部圆柱形磨料表面的心轴。通过宝石支撑结构可调整地保持的宝石接触表面。心轴可绕其中心轴线成角度地移动。它也可以沿轴线往复运动，以防止跨越面面的随机条纹的形成。可调节的稳定器可以被预设为接合在与心轴相邻的位置附着于宝石的多孔体。这确保了从芯轴移动后的宝石的准确重新接合，以便在刻面优先级期间进行中间检查。制造光学放大小面的方法需要宝石的连续分度并使其与角度移动的圆柱形磨料表面接触。所得到的宝石可以具有围绕其外表面具有圆柱形截面形状的一个或多个曲面。这些小面可以是凹的或凸的。通过对补充的移动的心轴表面进行抛光，可以在弯曲小面上产生带槽面的预选图案。

摘要： A matched pair of coaxial milling wheels for small flour mills such as those used in homes. A stationary milling wheel and an adjacent rotatable milling wheel each have a common central axis. Each includes first and second radial surfaces spaced along the axis. The adjacent faces of the wheels have a center cavity extending axially inward and defining the inner periphery of an annular milling face extending to the wheel periphery. Complementary grooves are formed in the milling face of both wheels to feed grain radially outward from the central cavities and to assist in cracking and grinding the particles to a fine state. The wheels are formed integrally from fired stoneware and have machined flat annular rims about the milling faces to assure accurate final grinding of the particles before they exit from the space between the two wheels.

摘要： An antibacterial cleaning composition for hard surfaces is made from a flexible superabsorbent material and an antibacterial agent. The composition can be applied to various liquid and solid surface contaminants, including blood, vomit, fecal matter, urine, glass, food, etc. The composition may be applied to the contaminated hard surface by several methods including pouring, rolling, spraying or foaming. Once cured, the antimicrobial cleaning composition is removed from the surface, taking the contaminant along with it and leaving behind a clean surface.

摘要： A surgical stapler comprising including an elongated handle portion having a longitudinal axis extending between a distal end and a proximal end. The stapler includes an end effector disposed at the distal end of the handle having a staple cartridge housing, and an anvil. The end effector has an open position wherein the staple cartridge and the anvil are spaced apart, and a closed position wherein the staple cartridge and anvil are closely adjacent to each other. The stapler also includes an elongated trigger. The distal end of the trigger being pivotably attached to the handle between the handle's distal and proximal end. The trigger has an open position wherein the proximal end of the trigger is spaced apart from the handle, and a closed position wherein the proximal end of the trigger is closely adjacent the handle. The trigger is linked to the end effector such that moving the trigger from its open to its closed position moves the end effector from its open to its closed position. The stapler also includes an actuator for ejecting the plurality of staples from the cartridge towards the anvil. The actuator includes a rotatable knob mounted onto the distal end of the handle, such that progressive rotation of the knob in a predetermined direction progressively ejects the staples.

摘要： A method for stapling tissue using the steps of providing a surgical stapling device having a handle with a longitudinal axis extending between a proximal end and a distal end having an end effector disposed thereon, which is substantially perpendicular to the longitudinal axis. The end effector comprising a staple cartridge housing a plurality of staples, the end effector having an open position and a closed position. The device also has an elongated trigger having a distal end and a proximal end, wherein the distal end of the trigger is pivotably attached to the handle. The trigger has an open position wherein the proximal end of the trigger is spaced apart from the handle, and a closed position wherein the proximal end of the trigger is closely adjacent the handle. Lastly, the device has an actuator for ejecting the plurality of staples from the cartridge towards the anvil, the actuator is a rotatable knob mounted onto the distal end of the handle. The method further involves the step of moving the end effector to its closed position by moving the trigger towards the handle. The method also involves the step of ejecting the plurality of staples from the cartridge by rotating the knob.

摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.
