IPC: A47L13/16
Filed: 1954-07-20
Abstract: 783,279. Chamois leather pads. COLMAN, J. Oct. 28, 1955 [July 20, 1954], No. 21163/54. Class 19. A chamois leather cleaning pad comprises a plurality of strips of leather threaded onto a core member looped to form the threaded strips into an annular pad. The pad may be formed by inserting a needle through one end of a first strip looping the strip, re-threading it on the needle, again looping strip and re-threading until the end of the strip is reached when a further strip can be similarly treated. The strips are then passed onto a thread or cord threaded into the needle and further strips are added as desired whereafter the thread is formed into a loop and tied. Alternatively a number of strips can be threaded onto the needle looped and rethreaded so that the strips are interlooped. This process may be assisted by arranging the needle at the centre of a ring of steel pegs so that the strips after being threaded onto needle are each wound round a peg to form a loop before being rethreaded. A handle 3 of plastic material may be provided if required.

Title: Improvements in and relating to manometers
IPC: G01L19/00
Filed: 1926-08-31
Abstract: 267,804. James, R. W., (Brown Instrument Co.). Aug. 31, 1926. Liquid-level pressure gauges.-The relative cross-sections of the legs of a manometer are changed in a series of steps so that a given sealing liquid level change in one leg may be produced by each of different but definitely related pressure-differentials impressed on the manometer. The housing comprises upper and lower chambered parts A, A<1>, of which the latter is provided with a float chamber D containing mercury or other sealing liquid. A channel E connects the lower end of the chamber D to a chamber G adapted to contain one of a series of standpipes F threaded into the end of the channel E. Passages H, H<1>, H<2> permit liquid from the channel E to flow into the space between the standpipe F and the chamber wall, a valve I being fitted between passages H, H<1>. The low pressure is communicated through the pipe L and the high pressure through pipe K and passages K<1>, K<2>. The standpipes are of different predetermined diameters to permit variation of range in definite steps, the wall thicknesses of the lower parts of the pipes F being so proportioned that the sealing liquid displaced by each part F when the valve I is open will be the same. The float C carries a magnetic core 0 adapted to vary the inductance of coils P, P<1> arranged in an impedance bridge. The core is arranged inside and coils outside of a tube B of non-magnetic screwed into the top of the chamber D. The tube should be of non- corrosive material, for instance an alloy 80 per cent nickel and 20 per cent chromium. To prevent oxidation of the core D by condensed steam or water an oil floating on the water is used in tube B. With the alteration in the levels under pressure water flows into and out of the chamber G. A removable plug B<1> serves for charging the instrument with liquid. Channels M<1>, K<1> when the valve M is open equalize pressures in the two legs. The manometer is made of cast iron and the float chamber D, and in some cases the enlarged part of the chamber G is provided with a lining of the alloy mentioned above to prevent corrosion. The float C is also made of non-corrosive material, and in some cases the pipes F also. The float chamber is provided with ribs S<1> on the lining to prevent the float engaging the wall. Specifications 266,616, [Class 106 (iv), Indicating &c.], and 271,304 are referred to.

Abstract: 850,758. Preventing corrosion. FLEISHHACKER, A. H. July 10, 1958, No. 22193/58. Drawings to Specification. Class 123(1) A method of protecting the metal interior of an oil tanker from corrosion, especially when carrying sea water ballast, comprises contacting the surface of the metal with a fog, i.e. an aerosol type of colloidal dispersion of a fluid corrosion inhibitor, to form a film of inhibitor on the metal surface. The inhibitor must be insoluble in water, non-volatile at the temperatures encountered when gas such as steam or from a flue is used for atomization, and preferably has a high affinity for metal. Raw wool grease, derivitives of wool grease, and compounds of water insoluble soaps are stated to be suitable compounds for use as inhibitors. The latter, before being converted into a fog, is preferably mixed with a liquid carrier comprising e.g. a petroleum distillate or transformer oil. The carrier must be insoluble in water, non-volatile and heat stable at the temperatures encountered, and is preferably non-toxic.
