Novel ligands of the general formula wherein r is 1 or 2, and L is a piperidine which is substituted by at least one enolate group in the 1-position or 4-position and wherein the ring nitrogen is sterically hindered by alkyl substituents in the adjacent positions. These ligands are useful in preparing light stabilizers.

Compounds of the formula I ##STR1## in which m is 0 or 1 and n is 1 or 2 and R, R.sup.1, R.sup.2, Z and X are as defined in claim 1, and also salts of these compounds, are valuable light stabilizers for organic materials, especially for polymers. The compounds of the formula I can be prepared from the corresponding 4-sec.-aminopiperidines by reaction with cyclic dicarboxylic acid anhydrides and appropriate further reactions.

The disclosure is directed to mechanical compressive shrinkage apparatus of the type comprising opposed feeding and retarding rollers arranged for cooperation with a confining shoe. Fabric or the like is advanced over the feeding roller, being maintained in contact therewith by the confining shoe. The feeding and retarding rollers are arranged to form a nip, and the fabric enters this nip immediately after its emergence from between the feeding roller and the confining shoe. The retarding roller, moving at a slightly slower rate of speed than the feeding roller, and having a superior grip on the fabric, causes the fabric to be decelerated at the nip and mechanically compacted between the nip and the shoe. The disclosed improvements are directed specifically to the construction of the confining shoe itself, enabling manufacture of the shoe to be accomplished at significant savings and facilitating maintenance and repair of the shoe. The shoe assembly includes a rigid support beam, to which are secured a plurality of contoured shoe segments whose length is a fraction of the length of the rigid support beam. A thin, contoured, liner element is secured over the working faces of the shoe segments, forming a continuous, uninterrupted working surface arranged for contact with the fabric. The liner plate is arranged for easy replacement to accommodate wear.

摘要:
A shipping carton includes a plurality of generally rectangular panels with a hinge between at least each two adjacent panels. The panels can be extended and placed at about right angles from each other to form a sidewall having an open top portion and an open bottom portion. A pair of support trays each comprising a panel member and four side members that extend therefrom fit over the portion bottom and top portion of the sidewall to enclose the carton. In a preferred embodiment, spaced-apart inserts and liner members can be provided which fit within each support tray. The panels and the support trays are secured to prepare the carton for shipping.
