Title: Method and means for the cathodic protection of tanks filled with sea water
IPC: C23F13/02
Filed: 1957-07-05
Abstract: 817,120. Preventing corrosion. RISBERG,. E. July 5, 1957 [July 5, 1956], No. 21437/57. Class 123(1) In an oil tanker vessel a tank 1 which is filled with sea water ballast is protected from corrosion by an impressed current anode 2 suspended therein and supplied with current through a cable 11. The anode is assembled from a number of annular sections 3 of graphite stacked inside a tight-fitting perforated sleeve 4 of insulating material such as polyvinyl chloride. The cylindrical cavity 5 formed inside the stack is closed at both ends by covers. A pipe 7 extending to the bottom of the cavity passes through the top cover and is connected to one section of a double pump 8 which withdraws water from the cavity, the water having passed on to the cavity through a filter 14 enclosing the anode and preventing access of suspended particles thereto, through perforations 9 in the sleeve 4 and between the sections 3. The :cavity may be vented to atmosphere or connected with a vacuum source by a conduit 10. To maintain the full level in the tank, the volume of seat water withdrawn is replaced by the other section of the pump 8 which delivers the water through a pipe 12 to the region immediately surrounding the anode through nozzles 13, thus preventing the oxygen contained in the make-up water from being distributed in the ballast. The flow of water into the anode and thence from the tank removes from the latter harmful and corrosive anode products such as chlorine and oxygen before they come into contact with the tank walls and prevents accumulations of gas in the tank top with consequent explosion hazards. When oil is loaded into the tank the anode may be removed. If, however, it is to be permanently mounted the supply cable 11 and conduits 7, 10, 12 are housed in a single tube, 15, Fig. 2, on which slides a bell cover 16. The cover has a float chamber 17 of such size that the cover floats in water but sinks in oil. When the sea-water ballast is removed from the tank the cover drops to enclose and protect the anode and remains in this position when the tank is filled with oil.

Abstract: 315,434. Soc. of Chemical Industry in Basle. July 13, 1928, [Convention date]. Yarns &c., treating with liquids. - Textile materials made of vegetable fibres are immunized to direct dyeing dyestuffs by treating them with maleic anhydride, if desired in the presence of a diluent and a catalyst. The treated textiles have a strong affinity for basic dyes. In examples (1) cotton yarn is immersed in fused maleic anhydride for half-an-hour and is then centrifuged or squeezed and rinsed, the product is scarcely affected by substantive dyes but is strongly dyed by basic dyes; catalysts, such as copper sulphate, are without noteworthy effect on the product but shorten the operation, and (2) cotton is treated with maleic anhydride in glacial acetic acid for about four hours; the product has similar properties to those of example 1.

Title: Method of adjusting the capacitance value of a capacitor

Filed: 1972-05-10
Abstract: 1388191 Capacitors WESTERN ELECTRIC CO Inc 10 May 1972 [12 May 1971] 21717/72 Heading H1M The capacitance of a capacitor is adjusted by relative movement of the plates and the plates are maintained in the adjusted position by setting dielectric material located between them. As shown polyethylene terephthalate strips 12, 13 bearing aluminium or zinc coatings 14, 16 are wound together, the roll is flattened, end contact layers are applied and the capacitor is impregnated through the porous contact layers with microcrystalline wax. To adjust the capacitance a D.C. voltage is applied across the plates while the temperature is raised until the wax is flowable. Electrostatic force draws the plates together increasing the capacitance and when an estimated value is reached corresponding to the desired value when the wax is solid, the capacitor is cooled to solidify the wax. The voltage, which should be above the rated breakdown voltage of one capacitor, is preferably maintained until the wax has set. Alternatively the impregnation may be carried out after the adjusting process which may then be repeated on the adjusted capacitor. Preferably the voltage is controlled by a system monitoring the capacitance as the plates are moving together.
