Title: Machine-tool for forming grooves
IPC: B23C3/30
Filed: 1964-10-22
Abstract: A machine tool comprising in combination a lathe and a milling-machine constituted by a main frame 1 having a work-table 2 mounted thereon for movement in a vertical plane and comprising a fixed head-stock 3 and a movable tail-stock 4. The main frame 1 has two identical lateral shoulders 5, each constituting slides for an auxiliary frame 6 which is movable in a horizontal plane perpendicular to the worktable 2. Attached to the frame 6 are orientable rectangular tables 7 movable in the vertical plane about a horizontal axis on an annular slide 8. A rectilinear slide 9 attached to the table 7 forms a guide for a tool-mounting carriage 10 to which is pivotally attached a tool plate 11 which is always located in a vertical position whatever the inclination of table 7 and carriage 10. The plate 11 constitutes a support for a plurality of milling cutters 12 which are angularly adjustable. The head-stock 3 is provided with workdriving spindles 25a and 25b driven via a gear transmission by a motor 37, which includes means for indexing the workpieces if required. The lower ends of the workpieces are supported and located on the tail-stock 4 by centres 43 and 43b. The movement of the frame 6, table 7 and carriage 10 are hydraulically operated from a pump 13, the frame 6 and carriage 10 being actuated by a tracer 20b and template 20a. The vertical movement of the work-table 2 is controlled by a motor 22 fixed to the frame 1 and by means of a screw 23 extending from the head-stock 3. The machine facilitates the machining of rectilinear or spiral grooves in workpieces of various cross-sectional shapes.

Title: Electrography
IPC: G03G15/22
Filed: 1966-04-29
Abstract: An electrographic apparatus and process for producing, on a record medium having a layer of insulating material in contact with an electrically conductive backing member, an electrostatic charge image corresponding to an image to be recorded comprises an image grid and at least one control grid arranged between a corona discharge device and the layer of insulating material. The image grid comprises an electrically conductive core having insulating and conducting areas defining the image to be produced. The control grid is electrically conductive and arranged in spaced and generally parallel relation to the image grid and between the latter and the corona discharge device. When the core of the image grid and control grid are individually biased to a potential for establishing electrical fields of different strengths between the respective areas and the backing member and a flow of ions is directed toward the grids and the record medium, the flow of ions through the grids is modulated by the electrical fields to produce an electrostatic charge image on the layer of insulating material.

Title: Antifouling covering
IPC: C08K5/57
Filed: 1967-03-30
Abstract: A covering resistant to marine fouling organisms comprises a reservoir layer 12 of material containing a toxic agent for poisoning or repelling marine fouling organisms, and a toxic agent transfer control layer 14 of elastomeric material between the layer 12 and the surface of the covering which is exposed to the fouling organisms in use, the transfer control layer 14 being capable of regulating the transfer of the toxic agent from the reservoir layer 12 to the outer face of the layer 14 to provide thereon a desired minimum concentration of the toxic agent. Both the reservoir layer and the control layer may be elastomers selected from neoprene, isobutylene-isoprene copolymers, styrene-butadiene copolymers, cis-polybutadiene, ethylenepropylene copolymers, polyether- and polyesterurethanes, butadiene-acrylonitrile copolymers, natural rubbers, epichlorohydrin rubbers, and silicone rubbers. The elastomers are preferably vulcanizable or cross-linkable with sulphur, sulphur-containing compounds, metal oxides, peroxides, or amines. The reservoir layer may be cellular e.g. an open celled polyurethane or p.v.c. foam. The elastomers used are preferably solvents for the toxic agent which is preferably an organotin compound of the formula (R 3 Sn) n X where R is an alkyl or phenyl group, n is 1 or 2 and X is a sulphide, oxide, chloride, fluoride, bromide, chromate, sulphate, nitrate, laurate, hydroxide, acetate, octanoate, resinate, dimethyl dithiocarbamate, naphthenate, paravinyl benzoate, acrylate, methacrylate, hydride, isooctylmercaptoacetate, or methoxide radical. Preferred compounds are exemplified. Preferably the layer 14 has a low solubility limit and the layer 12 a high solubility limit for the toxic agent, and the layer 12 may be super-saturated therewith. The layers may be produced by adding the toxic agent as a dry powder or oil to the elastomer at the polymerization stage or to a solution of the elastomer. The elastomers may be extruded, rolled, or moulded to shape, or calendered on to fabrics. The layers 12, 14 may be vulcanized together or secured by adhesive, and then vulcanized. The layers may be further laminated to metal, wood, plastics, fabrics, concrete or fibreglass, and are preferably secured as sheets or strips to ship hulls, buoys, or pier piling. In other examples the control layer envelopes the reservoir layer, or pads of the reservoir layer material lie between and are spaced by sheets of the control layer material.

Patent ES-437703-A1 (ES)
Title: Production of methane-rich gas
IPC: C07C1/02
Filed: 1975-05-14
Abstract: This is an improved continuous process for producing a clean methane-rich gas stream without the concomitant formation of particulate carbon which would ordinarily decrease the efficiency of the process and shorten the life of the catalyst. By-product superheated steam is simultaneously produced at a maximum temperature. The product stream may have a methane content up to 98 to 99 mole % or higher and a gross heating value up to 1000 BTU per SCF or more. Process steps include partial oxidation of a hydrocarbonaceous fuel under operating conditions that produce a synthesis gas containing 10 to 30 mole % methane (dry and CO2-free basis) and a H2/CO mole ratio of 2.6 or higher, and reacting the methane-rich process gas stream in one to three catalytic methanation stages under critical operating conditions that increase the methane content in the process gas stream stepwise up to 98 mole % or higher without incipient soot formation for each corresponding CH4 content of the feed as one proceeds from one methanation step to another. Heat from the highly exothermic methanation reaction is used to make valuable by-product superheated steam. The product gas may be burned without polluting the atmosphere.
