摘要： The present invention relates to a multi-layered seal ring capable of expanding for installation onto a shaft, rod or other cylindrical member, and then once in position, provides a seal as though it were a continuous solid ring allowing for only a minimal amount of leakage over a wide temperature range. More specifically, the present invention relates to first and second annular or non-annular forms having gaps or fractures in their structure, wherein the first and second annular or non-annular forms are affixed to one another.

摘要： A shock absorbing structure includes a body defined by a plurality of adjacent coils. The coils are resilient and flexible when exposed to a load applied substantially off-axis, or perpendicular to the axis of the body. In use, the body is positioned so that the coils deflect in directions substantially normal to the axis of the body. In this way, the body acts like a shock absorber, but unlike a coil spring, the shock is absorbed by the laterally inward or outward flexing of the coils, rather than the extension or compression of the coils themselves along their axis. The body can be formed by coiling a monofilament strand which is made of a polymeric material, such as nylon. Any number and types of articles can be made by incorporating the shock absorbing structures of the present invention, including, for example, articles of footwear, impact resistant bumpers, tires, and vibration dampening pads.

摘要翻译：减震结构包括由多个相邻线圈限定的主体。当暴露于基本上脱离轴线或垂直于主体的轴线的负载时，线圈是弹性的和柔性的。在使用中，主体被定位成使得线圈在基本上垂直于主体的轴线的方向上偏转。以这种方式，身体像减震器一样起作用，但是与螺旋弹簧不同，冲击被线圈的横向向内或向外弯曲吸收，而不是沿其轴线延伸或压缩线圈本身。可以通过卷绕由诸如尼龙的聚合物材料制成的单丝股线来形成本体。可以通过结合本发明的冲击吸收结构来制造任何数量和类型的制品，包括例如鞋类物品，抗冲击保险杠，轮胎和减震垫。

摘要： A continuous method for making a polymeric bristle subassembly using the steps of: continuously forming a wrap (6) of polymeric filaments by wrapping at least one filament (1) around the axis of at least a three sided mandrel having a moving cable support (4) on each corner running the length of the mandrel on the exterior corner of the mandrel capable of supporting and moving the polymeric filaments of the wrap (5) along the length of the mandrel; feeding at least one base string (8) outside of the wrap of polymeric filaments to a selected portion of the mandrel as required to form the subassembly, such as the corner or side of the mandrel, while the polymeric filaments of the wrap (6) are being moved the length of the mandrel; bonding the base string and the polymeric filaments of the wrap together by simultaneously pressing the base string in contact with the filaments of the wrap and applying energy to the base string and the polymeric filaments of the wrap; and cutting the polymeric filaments of the wrap at a point downstream of where the polymeric filaments of the wrap are bonded with the base string to form at least one bristle subassembly (11) having at least one row of filament segments connected to at least one base string. An apparatus for making the subassemblies is also part of this invention. Other aspects of this invention are a continuous method of making a bristle subassembly (11) wherein the base string is omitted and the filaments of the wrap are bonded to each other through the use of an energy source, or the use of a polymeric bead to bond the filaments together or use of a solvent or an adhesive to bond the polymeric filaments of the wrap together to form a bristle subassembly.

摘要： Bristle stiffness is varied by allowing a support beam (22, 66, 80) that carries the bristles (54, 55, 68, 82, 84) to undergo torsional movement in response to brushing action. Torsional movement is achieved by allowing the support beam to be disconnected to the brush head along at least portions of the length of the support beam. In particularly preferred embodiments, brushes employing the varying stiffness techniques are made with bristle sub-assemblies that have at least one row of bristles connected to a base string or similar structure that functions as a support beam. The base string can be connected across an opening in the brush, and is thus connected at its opposite ends, or it can be connected at any number of spaced intervals, the number and length of spacing being selected to achieve a desired degree of stiffness.

摘要： Several brush assemblies are disclosed. All employ bristle strings that include a base string (66) connected to a plurality of monofilaments (118). The preferred monofilaments are nylons and other polymeric thermoplastic materials. The monofilaments may be linear segments or loop segments (168a, b) disposed in two rows. The bristle strings may be connected to brush bodies to form virtually any of the various types of brushes. Bristle strings employing loops may be braided together to form entangled, monofilament articles for brush or other applications.
