Title: Protection of structures in sea water against fouling by marine growths
Inventor: HIGGINS WILLIAM FREDERICK
IPC: C23F13/02
Filed: 1958-01-03
Abstract: 852,882. Preventing fouling by marine growths. HUGHES & CO. Ltd., F. A. Dec. 12, 1958 [Jan. 3, 1958(2)], Nos. 265/58 and 266/58. Class 123(1) The fouling of structures, especially ships' hulls, immersed in sea water by marine growths is prevented by discharging against the underwater surface a growth deterrent consisting of a substantially insoluble liquid which may itself have a growth deterrent effect and/or in which is dissolved or dispersed a deterrent substance, the liquid containing from 0À05 to 0À4% by weight of a wetting agent, which may itself be toxic to marine growths, to improve the ability of the liquid to wet the underwater surface. Suitable carrier liquids are kerosene and light diesel oils whilst the compounds which can be dissolved or dispersed therein are solid metals or metal compounds such as the oxides of copper, arsenic or mercury and organic compounds such as 2:4 di-isobutyl phenol, phenyl mercury nitrate and acetate, pyrethrum, pentachlorophenol, derris extract, ethyl bromoacetate, zinc phenyl dithiocarbamate, diphenyl arsenious acid, dichlorodiphenyl-trichloroethane, and p-dichlorobenzene. Tri-alkyl or tri-aryl tin compounds as described in Specification 851,902 may also be incorporated. The wetting agent may be anionic, neutral or cationic, agents containing amine groups being preferred. Of the anionic agents "Armeen 12" and "Duomeen C" (Registered Trade Marks) are suitable and toxic amines and quaternary ammonium compounds may also be used. When cationic agents such as piperidine derivatives are employed the structure may be made a cathode in an electric circuit having anodes positioned in the sea water. The deterrent liquid alone or entrained in a carrier gas is discharged beneath the structure from perforated pipes so that the liquid or gas bubbles rise over the submerged surface to coat it with the deterrent.

Filed: 1938-01-05
Abstract: 508,700. Bobbins; treating textiles. DREYFUS, H. Jan. 5, 1938, No. 332. [Class 120 (iii)] [Also in Group IV] Yarn and similar textile material is wound on a bobbin, the barrel of which is coated with a solid substance which is soluble or readily dispersible in water and thus removable from the bobbin without removing the yarn or similar textile material. The coating may be covered by flexible sheet material, e.g. rubber or paper, which may be rendered impervious to the substance and any liquid used to remove it. The barrel of the bobbin may be perforated for treating the material with fluid and the bobbin has a detachable flange which is held against a shoulder on the barrel by a nut screwing on the end thereof ; the hole in the flange may overlap' the end of the barrel to prevent the yarn catching between the flange and barrel. The coating may be removed, wholly or partly, before or simultaneously with treatment with a fluid, e.g. a shrinking medium or the textile material may be treated after removal from the bobbin and a core inserted into the centre of the package so that it will maintain its shape. The coating may consist of a water-soluble carbohydrate or a carbohydrate derivative which is soluble or dispersable in aqueous media due, e.g. to degradation or to the presence of a hydrophile group in a substituent radicle, e.g. hydroxyalkyl ethers of cellulose produced as described in Specifications 166,767 and 277,721, [both in Class 2 (ii)], carboxyalkyl ethers of cellulose produced as described in Specification 343,521, [Group IV], or cellulose esters obtained as described in Specification 344,775, [Group IV]. Watersoluble synthetic resins, e.g. polymerized acrylic acid or partially saponified polyvinyl ester resins, or proteins which are soluble or dispersible in aqueous media, e.g. casein and gelatine, may also be employed. According to the Provisional Specification, the coating could be one soluble or dispersable in materials other than water, e.g. in toluene or ether, when the yarns were of cellulose acetate or the coating could be easily fusible, e.g. a wax.

Sodium aluminate may be produced from the aluminium hydroxide by reaction with NaOH solution.  MgCl2 may be obtained from the solution containing reaction products, K2SO4 and MgSO4 by treatment with KCl. MgCO3 and (NH4)2SO4 may be produced from the MgSO4 obtained in the initial reaction by treatment with ammonia and carbon dioxide.

Title: Electronic buzzer
IPC: H04R7/08
Filed: 1982-11-25
Abstract: A miniature electronic buzzer for an electronic watch has two vibrating plates with a sealed space between them forming an air spring. One of the vibrating plates carries an amarature which is acted upon by an electromagnetic to vibrate said plate. Vibration is imparted to the other vibrating plate by the air spring. The two vibrating plates and coupling air spring constitute a vibrating system having two resonant frequencies in the audible range. The electromagnet is energized by current having a frequency in the neighborhood of these resonant frequencies. There may be a third vibrating plate coupled with the second vibrating plate by a second air spring. In this event the vibrating system has three resonant frequencies in the audible range.
