Abstract: The present invention comprises a novel thermokinetic mixer. In one form of the invention, the mixing chamber shaft projections are removable at least in part and replaceable without cutting the projections from the shaft. In another form of the invention, only a tip portion of such projections are removable and replaceable without such cutting. In yet another form of the invention, shaft projections into the mixing chamber comprise a tooth having a substantially reticulated face forming a deflecting surface such that substantially all mixing chamber particles encountering the tooth strike and are deflected at an incident substantially lateral angle from the deflecting surface.

Abstract: A lacing aid which assists in lacing two elements tightly together comprises a first open portion that is easily threaded and engages a lace with reduced friction, and a second portion for frictional restraint of the threaded lace. Such lacing aids of the invention may be formed by bending smooth and stiff but resilient wire to form a first portion providing an opening larger than a lace with smooth inner walls, permitting the lace to slip easily when it is being tightened, and a second lace-restraining portion formed adjacent to the first portion to which a tightened lace may be easily slipped and engaged. An eyelet-connecting structure that may be used to fasten a lacing aid to a substrate element can be formed by two legs projecting from a junction, with one of the legs including a sleeve for rotatably carrying a first portion of the lacing aid and with the distal ends of the legs providing structure, such as a pair of mating fasteners, for fastening the lacing aid to a substrate, one mate being carried by each of the legs. Detent-forming structure adjacent the sleeve can hold the eyelet being carried so it extends upwardly and away from the leg. Such a connecting structure can comprise thin sheet steel bent into a U-shape, with one of the legs of the U being stamped to form notch-like portions and bent adjacent the notch-like portions to form a sleeve sized to engage the first portion of the lacing aid with a snap-fit so the first portion of a lacing aid is captively, but rotatably, carried by the U-shaped clip and can be held in the notch-like portions upwardly away from the connecting structure for easy threading.

Abstract translation: 有助于将两个元件紧密结合在一起的系带辅助件包括易于螺纹连接并且具有减小的摩擦接合花边的第一开口部分和用于螺纹花边的摩擦限制的第二部分。 本发明的这种系带辅助工具可以通过弯曲光滑而坚硬但弹性的线形成，以形成第一部分，该第一部分提供比具有平滑内壁的花边更大的开口，允许花边在被紧固时容易滑动，并且第二花边 - 紧固部分形成为与紧固的花边可容易地滑动并接合的第一部分相邻。 可用于将系带辅助件紧固到衬底元件的孔眼连接结构可以由从接头突出的两个腿形成，其中一个腿部包括用于可旋转地承载鞋带辅助件的第一部分的套筒 腿部提供结构的远端，例如一对配合紧固件，用于将系带辅助件紧固到基底上，一个伴侣由每个腿承载。 与套筒相邻的止动器形成结构可以保持携带的孔眼，使其向上延伸并远离腿部。 这种连接结构可以包括弯曲成U形的薄钢板，U的一个腿被冲压以形成切口状部分并且相邻于切口状部分弯曲以形成尺寸适于接合第一部分的套筒 的搭扣辅助装置，使得系带辅助装置的第一部分是由U形夹持件可旋转地支承的，并且可以被保持在凹口状部分中，远离连接结构，以便于穿线。
