IPC: F02C7/045
Filed: 2020-01-23
Abstract: The present disclosure relates to an aircraft noise reduction device, and effectively solves the problems of existing aircraft noise reduction devices such as low noise reduction effect of and poor control effect of the temperature difference. The technical 5 solutions of the present disclosure are as follows. The aircraft noise reduction device includes a housing. The inner wall of the housing is fixedly connected to a mufﬂer plate. An air mixing fan is coaxially connected to the mufﬂer plate to be rotatable. The rear side of the air mixing fan is provided with a spoiler fixing ring, and the spoiler fixing ring is slidably connected to the housing and can slide forward and backward. A 10 plurality of spoilers are fixedly connected inside the spoiler fixing ring, and each of the plurality of spoilers is provided with a plurality of spoiler mufﬂer holes. The rear end of the housing is fixedly connected to a collecting pipe, and the rear end of the collecting pipe is coaxially fixed to a ﬂow dividing plate. The outer wall of the ﬂow dividing plate is coaxially and fixedly connected to a jet nozzle. A plurality of sawtooth spoilers are 15 fixedly connected to the jet nozzle. In the present disclosure, the jet ﬂow is spoiled and converged multiple times, in conjunction with multiple holes and temperature control, which effectively solves the problem of jet noise, has a simple and stable structure, and possesses a high universality.

IPC: C23F13/02
Filed: 1966-07-08
Abstract: 1,147,754. Preventing fouling of marine structures; electrolysis; alloys. VICKERS Ltd. and CATHODIC & ELECTROLYTIC ENGS. CO. Ltd. July 6, 1966 [July 8, 1965], No.29085/65. Headings C7A, C7B and C7E. Fouling of a surface of a marine structure is prevented or eliminated by treating the surface with water electrolyzed using an anode and cathode electrically insulated from the surface, the anode providing during electrolysis ions of materials toxic to marine growths such as algae, bacteriological slime, mussels, barnacles or other animal growth, and comprising by weight at least “% As, ¢% Sb, or in the case of both arsenic and antimony together “% of each of As and Sb. The bulk of the anode may be of Cu, Fe or Al. For anodes of Cu, the toxic metal content by weight is “ to 2% As, ¢ to 6% Sb, or “ to 2% As together with ¢ to 3% Sb. For anodes of Fe, the toxic metal content by weight is “ to 2% As, ¢ to 6% Sb, or “ to 2% As together with ¢ to 4% Sb. For anodes of Al, the toxic metal content by weight is “ to 3% As, ¢ to 10% Sb, or “ to 2% As together with ¢ to 6% Sb. Typically there may be used in combination a Cu-As anode and an Al anode insulated from each other and the current to each separately controlled. If desired the two anodes may be in the form of a unitary structure but insulated from each other. Electrolysis e.g. of seawater may be effected ina container remote from the surface to be protected or in the medium in which the surface to be protected is immersed, the electrodes being disposed to ensure a passage of the toxic ions over the surface to be protected. If a separate container is used for electrolysis the container may form the cathode so the sea water electrolyzed may be heated. Examples are given of preventing fouling of ship hulls.

Title: 2-chloro-6alpha 9alpha-difluoro-16alpha-methylpregna-1
Filed: 1969-02-12
Abstract: Cpds. of formula (I) R' = OH opt. esterified or etherified Y = H, OH opt. esterified. Thymolytic, suprarenal inhibitory and anti-inflammatory activity. 0.3-3 mg/kg. orally or 1-10 mg/kg. s.c. in rats markedly inhibits foreign-body-induced granuloma. The thymolytic effect is 10 times greater than the anti-inflammatory effect when a 21-acetate is admin. orally. The 21-pivalate corresponding to the 21-acetate has a similar anti-inflammatory activity but the thymolytic activity is less than the anti-inflamm. activity. May be used in animal foods.
