    • An alpha alumina-based ceramic abrasive grain comprising, on a theoretical oxide basis, Al.sub.2 O.sub.3, Fe.sub.2 O.sub.3, and SiO.sub.2. The abrasive grain has a surface roughness height of greater than about 200 nanometers and a density of greater than about 3.50 g/cm.sup.3. Preferably, the alpha alumina-based ceramic abrasive grain has alpha alumina crystallites having an average crystallite size of less than about 0.5 micrometer (more preferably, less than about 0.3 micrometer). The presence of the SiO.sub.2 in combination with Fe.sub.2 O.sub.3 increases the amount of transgranular fracture of the abrasive grain, reduces the alpha alumina crystallite growth during sintering of the abrasive grain, dilates at least one of the unit cell dimensions of the abrasive grain, and generally improves the grinding performance of the abrasive grain.
    • 一种基于氧化铝的陶瓷磨粒,其以理论氧化物为基础,包括Al 2 O 3,Fe 2 O 3和SiO 2。 磨粒具有大于约200纳米的表面粗糙度高度和大于约3.50g / cm 3的密度。 优选地,α氧化铝基陶瓷磨粒具有平均微晶尺寸小于约0.5微米(更优选小于约0.3微米)的α氧化铝微晶。 SiO 2与Fe 2 O的组合的存在增加了磨粒的晶粒间断裂的量,减少了磨粒的烧结期间的α氧化铝微晶生长,使磨粒的单元电池尺寸中的至少一个扩大,并且通常改善 研磨性能的磨粒。

    • A backpack is disclosed having a sack including a stowage compartment and a frame holding compartment comprising an envelope having a front wall positionable against the wearer's back. A flexible unitary frame is positionable within the frame receiving envelope, under compression, and longitudinally tensions the front wall of the envelope. The unitary frame includes curved end portions interconnected by a pair of inwardly bowed, generally C-shaped side portions. The curved end frame portions fit the like curved closed end portions of the frame receiving envelope. The flexible frame is arcuate longitudinally and has a concave intermediate portion thus allowing inward movement of the tensioned front wall when contacted by the back of the wearer. Movement of the tensioned front wall causes the backpack to "hug" or closely fit the curvature of the wearer's back and thus moves the center of gravity of the backpack closer to the wearer's back to improve backpack balance. The portion of the front wall in contact with the wearer's back is formed from an open weave mesh allowing air to circulate over the back of the wearer.
    • 公开了一种背包,其具有包括存放隔间和一个框架保持室的袋,其包括具有可抵靠佩戴者背部定位的前壁的信封。 柔性单一框架可定位在框架接收外壳内,在压缩下,并纵向张紧信封的前壁。 单一框架包括通过一对向内弯曲的大致C形侧部互连的弯曲端部。 弯曲端框架部分配合框架接收外壳的类似弯曲的封闭端部。 柔性框架是纵向弓形的并且具有凹入的中间部分,从而允许张紧的前壁在穿着者的背部接触时向内移动。 张紧的前壁的运动导致背包“拥抱”或紧密地配合佩戴者背部的曲率,从而使背包的重心移动靠近佩戴者的背部,以改善背包的平衡。 与穿用者背部接触的前壁部分由开口编织网形成,允许空气在穿戴者的背部上循环。

    • A plastic tubular pack frame is disclosed employing a unitary main frame member and uniquel y constructed transverse support members including a pair of tee connectors interconnected by a tubular cross member. In one embodiment, a transverse support member is formed by heating a section of plastic tubing, placing the ends of the tubing on the pin portions of tee connectors and allowing tubing to cool and shrink onto the pins. The pin portions of the tee connectors include a series of circumferentially and axially extending ribs which engage the internal walls of the box ends of the cross member forming a connection normally fixed against axial disconnection and normally fixed against rotation but rotatable without fracture in response to above normal rotational torques.
    • 公开了一种塑料管状包装框架,其使用整体式主框架构件和单一构造的横向支撑构件,其包括通过管状横向构件互连的一对三通管件。 在一个实施例中,横向支撑构件通过加热塑料管的一部分而形成,将管的端部放置在三通连接器的销部分上,并允许管冷却并收缩到销上。 三通连接器的销部分包括一系列周向和轴向延伸的肋,其与横向构件的箱端部的内壁接合,形成通常固定以抵抗轴向断开的连接,并且通常固定抵抗旋转,但是可以响应于上述而旋转而不断裂 正常旋转扭矩。
