Abstract: 1283600 Removing phenyl azide from gases BADISCHE ANILIN- & SODA-FABRIK AG 12 Dec 1969 [13 Dec 1968] 60705/69 Heading C1A Phenyl azide is completely removed from gases containing it by scrubbing with sulphuric acid at a temperature which depends on the strength of the acid used, the useful range being room temperature to 150 C. corresponding to an H 2 SO 4  concentration of 100 to 50%. The use of 96% H 2 SO 4  at a temperature of 50-60 C., which is maintained by the heat of reaction, is described in the examples. The process is particularly applicable to purifying waste SO 2  from the bisulphite reduction of phenyl diazonium chloride to give phenyl hydrazine, the SO 2  then being absorbed in alkali and recirculated, but is applicable to purification of other gases e.g. air or nitrous gases.

Abstract: 1,222,616. Carbon paper &c. COLUMBIA RIBBON & CARBON MFG. CO. Inc. 30 Dec., 1968, No. 61724/68. Heading D2B. A pressure-sensitive transfer element comprises a flexible, inert, smooth plastics film having on its surface a thin imaging layer that is frangible and transferable under the effects of localized impact and consists of a porous network of polymeric binder having dispersed in it a porous filler and an ink that is exudable from it under the effects of an overall pressure lower than the impact pressure, the ink comprising an oleaginous material that does not dissolve and is not miscible with the binder and a colorant that is at least partially soluble in the oleaginous material and, over the imaging layer, a supercoating of adhesive material that has an affinity for both the imaging layer and a master sheet. When the transfer element is laid on top of a master sheet and local impact pressure applied, local transfer of the imaging and adhesive layers occurs; if a copy sheet is then laid on the master sheet and overall pressure applied, some of the ink exudes and forms an image on the copy sheet. In the examples: (1) lanolin, blown rapeseed oil, oleic acid, Victoria blue base, methyl violet base, a surfactant, clay, a vinyl chloride-acetate copolymer, toluol and methyl ethyl ketone are mixed and applied to a film of polyethylene terephthalate, the solvents are evaporated off, carnauba wax, polybutene, beeswax and mineral oil are applied as a hot melt and cooled; and (2) lanolin, blown rapeseed oil, mineral oil, surfactant, Victoria blue base, methyl violet base, clay, polystyrene, "Piccolite" (Trade Mark), toluene and xylene are mixed to form a transfer composition, which is applied as in Example 1.

Title: Separation of liquid materials having different densities
IPC: B01D17/02
Filed: 1978-11-22
Abstract: A floating platform (10) a central turbine (12) for inducing a downward draught of air to the on underside (34) of the platform, which has an inverted dish shape, so as to form underneath the platform a cushion of air at a slightly excess pressure to atmospheric to cause the platform to be lifted in the same manner as a hovercraft. Spinning centrifuges (18, 20) are mounted symmetrically around the central axis of the platform, the two centrifuges being adapted to rotate in opposite directions to produce a gyro effect causing the whole structure to be self-levelling even in rough seas. The continuous downward draught of air forces oil and water to enter the centrifuges through inlets (40, 44) and (42, 46). Water separated from the oil exits through outlets (52, 54) and oil is sucked up from the centre regions of the centrifuges through recovery pipes (30, 32) for storing in tanks located on the platform or in an adjacent floating vessel. <IMAGE>
