Title: Process for Preparing Gas Mixtures Having High Heating Value.
IPC: C01B3/38
Filed: 1967-09-11
Abstract: A gas, exchangeable with natural gas, is made by reacting a hydrocarbon feed in the gas phase with steam at 200-500 C. and a pressure of 1-200 kg./cm.2 gauge in the presence of a catalyst comprising Group VIII metals or copper and of an activator. Suitable activators are ammonia, hydrazine, hydrazines substituted by alkyl groups having 1-10 carbon atoms, and aliphatic amines having 1-10 carbon atoms and are used in amounts of 0À01 to 3% by weight, calculated as ammonia, of the hydrocarbon feedstock. The activator can be added continuously or intermittently into the reaction mixture either immediately before the latter is introduced into the reforming reactor or prior to a hydrodesulphurization of the feed. Ammonia can be added to the feed-water for steam reforming and the ammonia-containing water separated from the product gas can be recycled to the feed-water. Suitable feedstocks are propane, butane and light distillates boiling from 40-250 C. Hydrogen, oxygen, carbon monoxide, carbon dioxide and lower alkanols can be included in the feed. The O: C ratio in the feed is between 0À3 and 30 and between 0À8 and 1À8 if the reaction is to be autothermic. The product gas, after removal of carbon oxides and excess steam, consists almost entirely of methane and hydrogen. Suitable catalysts are made by impregnating a porous carrier, e.g. magnesium aluminium spinel with Ni, Co, Fe or Cu or by incorporating the catalytic metal during formation of the spinel by coprecipitation oxides of potassium and calcium can be included in the catalysts as promoters.

Title: Method of manufacturing printed circuits having metallised holes
IPC: H05K3/42
Filed: 1968-01-18
Abstract: A printed circuit board is provided with metalized through holes by coating the printed conductors and substrate with an electrically conductive layer and then an electrically insulating film, piercing the holes through the substrate, metalizing the walls of the holes by electrolysis, and removing the film and conductive layer. In a first example a copper, paper laminated sheet is silk screened with a resist and etched to form the printed conductors on both sides, after which the two faces of the sheet are covered by a thin aluminium layer by evaporation. The sheet is then dipped in glycerolphthalate, dried and immersed in a solution of aluminium stearite in toluene. After drying, the holes are pierced and the sheet seeded by a solution of palladium chloride and hydrochloric acid and a solution of stannous chloride in hydrochloric acid. Copper is then electroless deposited by dipping in a solution of sodium-potassium-tartrate, sodium hydroxide, copper sulphate, ethylene diamine tetra acetic acid and formaldehyde. A further layer of copper is then deposited electrolytically the aluminium coating providing an electrical connection between a contact and the copper in the holes. The lacquer is removed by dipping in trichloroethylene and finally the aluminium is dissolved in a sodium solution. In a second embodiment a copper clad epoxy resin reinforced by glass fibre sheet is photo-etched to produce a printed circuit pattern after which a thin copper layer is deposited over the sheet by a seeding and electroless deposition process followed by a silicon lacquer film. The sheet is then pierced and the walls of the holes coated with copper as in the first embodiment, the thin copper layer acting as an electrode instead of the aluminium. The silicon lacquer film is then removed by brushing and the thin copper layer dissolved by ferric chloride from the face carrying the printed circuit pattern. Nickel is then electroplated on to the exposed pattern and holes by supplying current to the thin copper layer on the opposite face which copper layer and covering of lacquer are finally removed by dissolving and brushing.

Title: Prestressed concrete structures and a process for making them
IPC: E04C5/08
Filed: 1968-03-15
Abstract: A tendon 4 in a pre-stressed concrete structure, comprises one or more "wires" 8 coated tightly and uniformly with a plastics material 10 which provides a coefficient of friction between the "wire" and coating of not more than 0.09. By "wire" is meant a filamentary material having an elastic limit of at least 150,000 psi, e.g. carbon steel or fibre glass. The wire diameter may be less than 0.03 ins. The plastics coating 10 may be up to 0.05 inches thick and formed about the wire by extrusion moulding. The plastic coating may be made of tetrafluoroethylene polymers and copolymers, polyamides and copolymers thereof, polyolefines, e.g. polyethylene and polypropylene, polystyrene, ABS resins, halogenated polyolefines, e.g. polyvinyl chloride, ethylene-methacrylic acid copolymer polyoxymethylene or polyethylene terephthalate. A lubricant may be as a film on the wire or it may be incorporated into the plastics coating. Specifled lubricants are (a) graphite, molybdenum disulphide and oils, e.g. silicone oil, for incorporation in the plastics and (b) mineral oils, hydrocarbon oils, graphites, and fluorocarbon polymers used alone or in combination with oil for use as a layer on the wire. A corrosion inhibitor, e.g. sodium nitriate ethanolamine or lauryl amine and a dispersing agent e.g. sulphonated hydrocarbons, sulphonamides and fatty acid salts can be present on the wire. In a modification, the "wire" has a first coating of plastics applied directly to the wire and a lubricant present between this first coating and a second coating functioning as the abovementioned coating. The tendon may be formed with a plurality of coated and lubricated wires in side-by-side and preferably separable, arrangement, see Figs. 6-11 not shown. The tendon is used for post-tensioning in concrete articles to hold the latter under compression. The tendon may lay in curved bent or rectilinear paths in the concrete. The total angle through which the tendon curves or bends may be up to 2000 . The tendon 4 may be anchored in a crimped metal sheath 92, the latter abutting a bearing plate 80, see Figs. 24-26 not shown. The anchoring may be filled with grouting.
Patent ES-362773-A1 (ES)
Title: Doll with rotatable body and appendage rotatable in delayed relation thereto
IPC: A63H13/12
Filed: 1969-01-21
Abstract: An animated figure toy comprises a body including a torso and appendages attached thereto, and a spot holding mechanism (which enables an appendage to remain stationary during at least part of a complete rotation of the torso and thereafter rapidly to rotate so as to "catch-up" with the torso) which is supported by the said body and is described with reference to "head-spotting". A head support block (150) defines a cavity (152) and is mounted on a shaft (156) which also carries a gear (157), and a cam (155), and at its upper end carries an element 161 having a stop 162. A torsion spring (154) is mounted in the cavity and fixed between the block (150) and the cam (155). Additional components are the cam follower (170) and arm (163) which is biased by spring (165) toward the stop, follower (170) and arm (163) being mounted on the same rod (168). Cam (155) is fixedly attached to the torso (122) and thus when the torso is operating to perform a pirouette motion the cam is also caused to rotate. The support block rotates with the torso only until extension (162) of element (161) engages the arm 163 when the position of the head becomes fixed, the motion of the torso being free to continue by virtue of the spring (154). The head remains fixed until cam follower (170) is displaced by the cam, when the displacement is transmitted to arm 163 via rod 168 which frees the head to rotate in the direction of motion of the torso. Due to the biasing action of the spring 165 the arm is immediately returned to a position in which it prevents the support block, and hence the head, from rotating again until the torso has rotated through a further 360 and head spotting is thus achieved. The means by which the body is caused to rotate is disclosed and claimed in co-pending Application No. 33071/70.
