    • A composition and method of fabricating pressureless sintered 70 volume % silicon nitride—30 volume % barium aluminum silicate ceramic composites. The composites are made from 70 volume % silicon nitride, containing varying amounts and size distributions of initial &bgr;-silicon nitride, and 30 volume % barium aluminum silicate. The resulting ceramic composites contain microstructures with coarse &bgr;-silicon nitride whiskers, as well as narrow distributions of short &bgr;-silicon nitride whiskers, surrounded by fine barium aluminum silicate grains. The resulting composites exhibit improved fracture toughness and flexural strength.
    • 一种制造无压烧结的70体积%氮化硅-30体积%的铝酸钡钡陶瓷复合材料的组合物和方法。 复合材料由70体积%的氮化硅制成,含有初始β-氮化硅和30体积%的铝酸钡铝的变化量和尺寸分布。 所得到的陶瓷复合材料包含具有粗糙的β-氮化硅晶须的微结构,以及由细的硅酸钡铝颗粒包围的短β-氮化硅晶须的窄分布。 所得复合材料显示出改善的断裂韧性和抗弯强度。

    • An adjustable handle bar assembly for a physically-guided implement such as a tiller having a handle bar rotatively mounted in a handle bar socket provided by a curvilinear panel web end and curvilinear margins of recesses formed in side flanges of a handle panel. An adjustable connection between the handle bar and the side flanges selectively adjusts the angular disposition of the handle bar in its socket. The rotative axis of the handle bar in the handle bar socket is defined by the curvilinear panel web end that embraces one side of the handle bar and the curvilinear margins of the recesses in the side flanges which embrace the other side of the handle bar. The adjustable connection includes laterally spaced arms secured to the handle bar, a bracket secured to each of the side flanges, and fasteners detachably connecting the spaced arms of the handle bar to the brackets.
    • 用于物理引导的工具的可调节手柄组件,例如具有可旋转地安装在手柄杆插座中的手柄的手柄,该手柄杆由曲线板腹板末端提供,并且在手柄面板的侧凸缘中形成凹槽的曲线边缘。 把手杆和侧面凸缘之间的可调节连接可选择性地调节手柄在其插座中的角度布置。 手柄插座中的把手的旋转轴线由包括手柄一侧的曲线板腹板端部和包围手柄另一侧的侧凸缘中的凹槽的曲线边缘限定。 可调连接件包括固定到把手的侧向隔开的臂,固定到每个侧凸缘的支架,以及可拆卸地将把手杆的间隔开的臂连接到支架上的紧固件。

    • The body 12 of an air gun accommodates a removable magazine 16 immediately behind the breech 14, for pellets to be loaded one at a time from the magazine into the breech. The magazine comprises a drum 33 which is rotatably mounted within a housing 31 and comprises ten pellet-holding slots 38 around its axis. A torsion spring 42 urges rotation of the drum in indexing steps as controlled by an escapement mechanism comprising a rocking pawl 50. The pawl is displaced against the action of a return spring 58 by a plunger 60 which projects from a cocking arm 22 of a conventional cocking mechanism of the gun; the plunger is arranged to actuate the escapement only towards the end of a cocking stroke of the arm 22. A loading ram/air transfer tube 28 is reciprocated, in effecting the cocking action, to withdraw from one slot 38 in the drum and enter a next slot to load a fresh pellet into the breech.

    • An oil-filled, pad-mounted tank for electrical distribution transformers, where the tank includes a front panel, a rear panel, a pair of side panels, a top panel, and a bottom panel that are joined to form an enclosed volume for receiving a transformer core and windings and a quantity of insulating oil. The side panels include a plurality of side panel sections that may include both curved and flat panel sections. Each side panel includes at least one curved panel section that is curved concavely and at least one curved panel section that is curved convexly. Each side panel section may also include one or more flat panel sections.
