Abstract: Photopolymerisable mixts. comprise 50-80% copolymer (A), 20-50% polyfunctional monomeric crosslinker (B) and, optionally, inhibitors and sensitisers. (A) is prepd. by copolymerising 25-60%, pref. 35-50%, of aliphatic monounsaturated carboxylic acids or anhydrides with 3-12C atoms, 15-50% pref. 23-46% acrylonitrile and/or vinyl chloride, and 5-60% of >=1 monovinyl cpds. pref. acrylic esters and styrene. (B) consists of a diacrylate or dimethacrylate of a glycol or oligoether of a glycol, or other divinyl or diallyl cpds.

Title: Packing gland for rotary or axial movement - is esp. designed for easy fitting and replacement
Inventor: EBBINGHAUS ALFRED DIPL-ING
IPC: F16J15/18
Filed: 1973-10-05
Abstract: The gland is in tubular form, internally threaded at the mouth for reception of a gland nut.

The gland provides a seal around an operating rod which carries a head at each end. The inner head can rest, against the washer, or in another plane. It may extend radially further, to a maximum width just less than the diameter of the washer, so that, if pushed inwards and turned, it may rest on the inner side of the projections. If replacement of the packing material becomes necessary, after unscrewing the gland nut the whole assembly can be withdrawn by pulling on the head.
