Title: Method and apparatus for deposition of materials by thermal decomposition
Inventor: NACK HERMAN
IPC: C23C16/48
Filed: 1954-03-17
Abstract: 749,293. Coating metals. COMMONWEALTH ENGINEERING CO. OF OHIO. March 17, 1954, No. 7812/54. Class 82(2). Workpieces are coated with metals by subjecting them in a chamber to the action of a gaseous metal carbonyl in a high voltage unidirectional electric field, the work piece forming the cathode. The outlet of the chamber may constitute the anode. A hollow member containing radium or uranium may be inserted into the gas stream to ionise the gas before entry into the chamber. The workpiece may be heated to the decomposition temperature of the carbonyl. Coating metals include Cr, Fe W, Co, Mo, Re, Ni, and may be deposited on e.g. the following bases : steel, Cu or brass, cast iron, Al, Mg. The carbonyl is admitted to the chamber 1 through a pipe 2. The workpiece 6 is supported on an electric heater 4 by electrically insulating members 15 and is connected at 7 to the negative pole of a D.C. supply. The outlet 3 of the chamber forms the anode.

Abstract: 678,583. Wooden tubes. MOE, H. N., and INTERESSENTSKABET INTERPLY. March 29, 1950 [March 29, 1949], No. 7825/50. Class 99 (ii) Tubular wooden bodies of coiled veneer sheets with an alternating fibre direction are produced by placing a stack of veneer sheet with alternating fibre direction, applying a binder between each sheet, and coiling the stack on a mandrel before the binder is hardened so that the ends of the stack will overlap, and joining the ends together by local heating of the joint by applying a high-frequency field between the mandrel and a pressure roller. The mandrel 1 is composed of segments one of which is insulating and carries an electrode. Pressure roller 8 is urged on to the mandrel by air operated pistons in the cylinders 20. The mandrel may be radially contractable by hand wheel 16. Both the mandrel and pressure roller may be internally heated and the roller and mandrel electrode form a H.F. circuit to set the joint whilst the tube is on the mandrel. A metallic, paper or textile sheet can be inserted in the stack of veneers.

Abstract: 1,208,281. Sealing outlets into plastics bags &c. PORTER-LANCASTRIAN Ltd. 5 Jan., 1968 [18 Feb., 1967], No. 7857/67. Heading B5D. A device to enable outlets to be heat-sealed progressively to a tubular web in the making of bags, the interior of which must be kept sterile during manufacture, comprises a carriage having means to guide a portion of the surface of the tubular web, within which the carriage floats, over a platen mounted on the carriage and support means preventing movement of the carriage by the moving web. Tines 14, extending lengthwise of the web and forming part of the carriage 13, guide the web 12 over the platen 11. An external heated sealing element co-operates with the platen 11 for securing the outlet (not detailed). Rollers 17, fixed to the outermost tines, engage with external support cylinder 16 and prevent movement of the carriage. At the sides of the carriage are guides 18 the ends of which, 18b, are resiliently pivoted outwardly to assist in separating the layers of the web. Alternatively the guides 18 could be resiliently mounted as a whole. After the outlet has been attached the tube is heat-sealed transversely (not shown) to form the bags.

Title: Rapid filter plant for the preparation of water and a method of operating the plant
IPC: C02F1/00
Filed: 1966-02-28
Abstract: Raw water to which flocculant may have been added continuously or intermittently is introduced through nozzles or openings arranged at intervals along a pipe in a closed chamber maintained full of water under pressure.  Flocculation occurs in the circulatory flow produced, and in the interstices of a shallow coarse-grained filter bed through which the water flows downwards. The filtered water is passed upwards to the inlet of a further filter operating under gravity at atmospheric pressure and having a deeper bed of finer-grain material through which the water again flows downwards. Each bed is washed by combined upward flow of water and air.  Four secondary (fine-grain) filters may be disposed above two primary (coarse-grain) filters.  One primary filter may be washed by water treated by both the other primary filter (temporarily operated at increased speed) and the four secondary filters.  One secondary filter may be washed by water treated by the other three secondary filters.
