Title: Converging flow separator
IPC: B01D45/04
Filed: 1980-09-24
Abstract: A separator for removing solids from a gas stream comprises a conical housing 29 enclosing a stack of spaced, annular segments 31 of progressively decreasing diameter in the direction of flow, each segment including a lip or flange at the downstream end thereof to deflect solids striking same into the centre of the stream whilst permitting gas to pass between adjacent segments for removal from the separator.

Title: Method for stabilising the viscosity of natural rubber during storage
IPC: C08K5/405
Filed: 1981-03-20
Abstract: The viscosity of natural rubber is stabilised during storage by the addition of thiosemicarbazide or its salts produced by the addition of an acid.
