摘要： Disclosed is a tubular core on which sheets of metal or other material can be wound and supported, for shipment, handling and dispersal, and a method for forming the core. The core comprises a metal sheet or strip which has a rectangular-ribbed cross-sectional profile of flattened ribs, and which is wound spirally into a tubular configuration. The core is formed by passing the strip through a plurality of roll-forming stands, to initiate forming and progressively form an arcuate ribbed sinusoidal profile, then a final roll-forming pass is used (or several such passes are used) to flatten the ribs of the profile so that the rectangular flattened ribs collectively form a support surface for the sheets which are wound and supported on the core.

摘要： A plastic coupling for joining two metal pipe sections end-to-end to form a pipe assembly. A first plastic spigot cuff is formed along the periphery of the end of the first pipe and a mating second plastic bell cuff is formed along the periphery of the end of the second pipe, such that the first and second cuffs form a bell and spigot joint with the first, spigot cuff inserted into and joined to the second, bell cuff.

摘要： Modified-profile metal strips, and annular and spiral metal pipes and other products formed from such strips. The strips comprise a plurality of spaced longitudinal ribs of size and transverse location selected to increase the strength of a given thickness or gauge of the strip and the associated strength of a product formed from the strip.

摘要： A coupling for joining metal pipes or pipe sections end-to-end to form a pipe assembly. A plastic cuff is formed on one of the pipe ends and a mating, second plastic cuff is formed on the other pipe end. In one embodiment, a wire hoop is mounted over each pipe end, the hoops are rotatable around the associated pipe ends to align the hoops, and bolt assemblies spanning the two hoops are used to tighten the hoops axially, to thereby clamp the pipe ends and compress the cuffs between the pipe ends and provide a leak-proof joint. The cuffs are selected from configurations including tongue-and-groove and bell-and-spigot. The cuffs can be formed on the pipe ends in the shop, then the pre-cuffed pipe sections can be readily assembled into stable, leak-proof, corrosion-resistant lengths of pipe in the field.

摘要： The useful life of a dry abrasive blasting head is greatly extended by two design features. First, the tube on which the rotating nozzles are mounted is protected from abrasion by an easily-replaced wear tube which is a sleeve-like liner. Secondly, the relatively expensive nozzle holder is protected by providing it with a cup-shaped cavity facing the incoming abrasive particles. The cup-shaped cavity soon becomes at least partially filled by the particles, so that later-arriving particles strike the particles contained in the cavity and do not directly reach the nozzle holder, thereby prolonging its life. Taken together, these structural features of the present invention result in a high-performance blasting head that can operate for more than 1,000 hours without interruption.
摘要翻译： 干式喷砂头的使用寿命通过两个设计特点大大延长。 首先，通过易于更换的耐磨管（其是套筒状衬垫）来保护安装有旋转喷嘴的管道免受磨损。 其次，相对昂贵的喷嘴保持器通过为其提供面向进入的磨料颗粒的杯形腔来保护。 杯形腔很快变得至少部分地被颗粒填充，使得后来的颗粒撞击容纳在空腔中的颗粒，并且不直接到达喷嘴保持器，从而延长其使用寿命。 总而言之，本发明的这些结构特征导致能够在不中断的情况下操作超过1000小时的高性能喷砂头。
