Title: Hypochlorite removal from aq. alkaline streams - by decomposition with hydrogen peroxide, opt. added in stoichiometric excess
IPC: C02F1/72
Filed: 1974-09-11
Abstract: Thorough removal of hypochlorite ions from aq. streams is achieved by adding >=1 mole H2O2 for each mole OCl- present, at pH>8.5. Reaction is quantitative, quick independent of hypochlorite concn., without by-prod. formation and any excess H2O2 decomposes gradually. Heat of H2O2/OCl- reaction is low and the process is unaffected by presence of other chemicals, e.g. caustic alkali, Cl2, carbonates, heavy metal ions, chlorohydrocarbons, dissolved salts.
Patent FR-2265688-A1 (FR)
Title: Subdivided biological oxidn. tank - for water purificn. and clarification
IPC: C02F3/12
Filed: 1974-11-28
Abstract: Oxidn. tank, for the biological purificn. of water, is subdivided by walls so as to form three separate tanks. The water to be treated enters via a pipe and sets up a spontaneous circulation; the water is highly agitated and oxidised by a turbine or by an air blower. The water flow from the first tank to the second tank, at a 10 cm lower level. The second tank is also fitted with a turbine and the same oxidn. process takes place. All this is repeated in a third tank which, however, is connected directly by a pipe with the settlement tank. The purified water leaves the plant while the pump sucks up the sludge and brings it back into circulation. The different tanks can be taken out of commission should there by any irregular functioning of the bacteria in one of the tanks, by making use of (I) with its various valves. Any substances harmful to the bacteria would act exclusively in the first tank; they could either be excluded from entering the other tanks or they could be given a suitable treatment before going to the next tank. If the arrival of liq. for purificn. is reduced for any reason, the oxidn. phase is restricted to the number of tanks necessary to deal with the quantity and organic loading of the water. Maintenance and cleaning of each tank as required can be effected without interrupting the operation of the plant as a whole.

Title: Centrifugally operated safety device - for yarn chopping machines preventing acces until cutter head is totally ar rest
IPC: F16P3/08
Filed: 1975-03-07
Abstract: Safety device for yarn chopping machines e.g. for producing staple fibre, with cutters rotating in a horizontal plane and fixed to a blade-carrying head, in which the part used to fix this on the motor shaft is provided with hammer-type mobile weights, which swing out to an exterior limiting position when the head is rotating as a result of centrifugal force and then rotate above a ring fixed to the cover of the protective housing and which, when the head stops, swing towards the centre of the motor shaft as a result of gravitational force, into a limiting interior position, and thereby unlock the protective cover. Prevents accidents due to the cutter head continuing to rotate for some time after the motor has been switched off by the usual interrupter on the cover, since access to the head can now only be obtained when this comes to rest.

Patent FR-2286329-A1 (FR)
Inventor: ROSA GIOVANNI
IPC: G05D1/02
Filed: 1975-09-24
Abstract: This invention relates to an improved method for rapidly laying a pipeline in deep water by an anchored floating means. The rapid laying is obtained by varying the forces exerted by winches mounted on the floating means in such a manner as to impart a rapid movement to the floating means, in the longitudinal direction of laying, for a distance equal to the length of the piece of pipe added to the free end of the pipeline to be laid. Before termination of the rapid movement there is applied to the floating means a compensating force, whose direction, sense and intensity are such that, together with the forces exerted by the winches, said compensating force opposes moment by moment the central elastic force which induces a damped oscillatory motion in the floating means. This oscillation is thus eliminated or drastically and rapidly dampened.

Title: Methacrylic acid, ester or nitrile prepn. - from propionic acid, esters or nitrile by alumina-catalysed reaction with methylal
IPC: C07C51/353
Filed: 1976-04-20
Abstract: Methacrylic acid or its esters or nitrile are prepd. by reacting prepionic acid or its esters or nitrile with methylal, esp. at 300-400 degrees C, in the presence of a catalyst consisting of or contg. Al2O3 which was preheated to >600 degrees C.
