Title: Casing for replaceable radioactive gas filter - has two=part closure plate for separately sealing filter unit and wall between dirty and clean sides
Inventor: JANNAKOS KONSTANTIN
IPC: B01D46/24
Filed: 1981-09-30
Abstract: A filter casing for a radioactive gas filter is designed to enable the annular or cylindrical filter unit (6) to be replaced, while at the same time the gas opening (5) leading from the dirty side to the filter is sealed during replacement. The filter casing has a pivoting lid (7) and means for securely pressing the filter unit against the opening during use. A closure lid for providing the sealing action is composed of two parts (25,26). The upper part (25) is associated with the outlet of the filter unit (6), while the lower part (26) is associated with the opening (5) in the partition (2) separating dirty and clean sides. These two parts (25,26) can be tightly pressed together with a seal (28) between them to form a double closure containing an uncontaminated space (29) between the two parts while in the pressed together state (as shown) the two parts can be lifted away from the opening (5) to allow free flow of dirty gas to the filter, this lifting action being provided by the closure movement of the lid (7) to the filter unit. Used in particular for the filtering of contaminated substances from a gas flow, where it is important that when the filter unit is replaced contamination does not spread. While the filter unit is being replaced, one part closes the opening (5) between the dirty and clean sides (4,3), while the other part closes the inlet to the filter so that this is sealed before the filter unit is removed.

Title: Preventing premature crosslinking of polymers prior to moulding - by grafting poly:thiol diene adduct on base polymer, e.g. polyolefin or acrylonitrile!
IPC: C08G75/045
Filed: 1982-03-24
Abstract: Prods. comprising (partly) crosslinkable synthetic materials and which must be subjected to physical agents such as heat, pressure and/or moisture during processing, storage and/or transport, are modified by grafting 2 c=c gps. on a tetrafunctional polythiol crosslinker and then grafting the thus modified polythiol on the chains of a base polymer. The latter is then stored in the absence of light and is subsequently moulded, pref. by extrusion, and then crosslinked by the action of UV, X or beta rays. The process ensures that a crosslinkable compsn. does not become prematurely crosslinked before it is moulded. The base polymer may be e.g. opt. halogenated polyolefins or acrylonitrile.
