Title: Epoxidation and hydroxylation of olefinic cpds. - with catalyst recovery by burning distn. residue in inert turbulent layer-contg. reactor (BE170476)
IPC: C07D303/04
Filed: 1975-10-22
Abstract: Catalysts used in epoxidation or hydroxylation of water-insol. olefinic cpds. with H2O2, are recovered by introducing the catalyst-contg. distn. residue into an inert matl. in turbulent motion and burning the org. components in distn. residue with O2-(contg. gases), pref. air. The catalyst cpd. deposited on the inert turbulent material, together with the catalyst cpd. collected in a solids separator connected behind reactor, are leached out with water and the soln. obtd. is re-used for epoxidation or hydroxylation. The process is esp. used for recovery of transition metal catalyst, partic. W cpds., e.g. used in epoxidation or hydroxylation of allyl alcohol with H2O2. Catalyst can be recovered quantitatively and re-used without loss of activity. The process causes no pollution.

Title: Floating barrage of inter-articulating vertical panels - used e.g. for gathering oil from sea surface, can be towed or stand on bed in shallows
IPC: E02B15/10
Filed: 1976-11-03
Abstract: The floating barrage is constructed of vertical panels which are coupled by their vertical edges to form a continuous horizontal elongated curtain of variable geometry. The couplings provide for inter-articulation of panels, and the barrier is for use in collecting oil or other pollution-debris from the sea, or for preventing the pollution of selected confined coastal waters. The barrier can be towed by surface shipping or stand freely on the sea bed in shallow waters. The bases of the panels are ballasted and include valves which open automatically to relieve differential water pressure on the panel faces. A combination of integral floats and ballast associated with the couplings maintains the barrier vertical. The couplings may comprise vertical bars with a spherical base for ballast, a radar beacon on the head, and auto-spreading legs attached to the base. The panels may be attached by links to eyelets, and subsidiary stays may be deployed when the barrier stands on the sea-bed.
