Title: Oxidation of sulphides in hydrocarbons - using phthalocyanine catalysts
IPC: C05B11/06
Filed: 1969-12-23
Abstract: Sulphur-containing compounds and their salts are oxidised by contacting the compds. with a gas contg. molecular oxygen, and with a solid catalytic mass prepared by mixing a solid transition metal phthalocyanine with a support, and an alkali metal oxide or hydroxide, the amount of phthalocyanine being 0.05-50% by wt., relative to the support, and the amount of alkali metal oxide or hydroxide being 10-50% by wt. relative to the total catalyst mass. The phthalocyanine pref. contains Co, V, Cu, Fe or Ni as metal, and the support is pref. carbon. The sulphur-contg. compds. are pref. present in hydrocarbon cuts.

Title: Flexible reservoir for fermentation tower - for prodn of methane from sewage and farmyard wastes
IPC: C12M1/107
Filed: 1975-02-19
Abstract: In a flexible fermentation tower used for obtg. a gas, contg. a high proportion of methane, from the organic constituents of waste water and sewage by anaerobic putrifaction, non-rigid matls are used to replace the rigid matls. used hitherto., although the method of operation remains the same. The flexible reservoir is made from a polyester fabric, coated on both sides with polyvinyl chloride, to form a cylinder with an attached base and a roof. The reservoir is suspended on a steel framework which rests on a reinforced concrete foundation which has the shape of a shallow basin. Inlet and outlet conduits, for the fermentation mass, are buried in the concrete and are connected to the base of the reservoir by flanges. An escape pipe for the gas is provided in the roof while a gutter surrounds the reservoir to prevent any pollution of the ground. The tower operates at temps. higher than 30 degrees C., so it is desirable to apply an insulating layer of polyurethane foam or panels of cellular material over the whole construction. The flexible tower is more easily handled and is much less expensive than the rigid variety. The gas produced is used as an energy source for the prodn. of heat or electricity.

Title: Cap protecting motor horn air filter against dirt - extends over adjacent electrical terminals
IPC: G10K9/22
Filed: 1975-06-12
Abstract: An electrically-energised source of sound is enclosed within a chamber (16), one of whose surfaces (15) acts as a sounding board. To prevent possible corrosion due to accumulations of moisture inside, the chamber is furnished with an air filter (21). This filter is protected against clogging by accumulations of dirt. It is proposed to place over the filter a labyrinthine cap (22) made of insulating material, leaving only a small air gap (25) at the inner side between the cap and the body of the chamber. As the air filter is situated between the horn's electrical terminals (17), the cap would be fitted over the terminals and afford them, too, protective cover.
