Patent ES-331245-A1 (ES)
Title: Plug and tapered candle
IPC: F21V35/00
Filed: 1966-09-15
Abstract: A plug has a central cylindrical part 44 and a plurality of angularly spaced apart strips 45 each of which extends substantially tangentially from the central part, the strips having outer edges which make line contact with a common circle and the strips being resiliently deformable so as to permit them to be introduced into and resiliently retained within a bore whose radius is less than that of said common circle. In the construction shown the central part and the strips are one end portion only of the plug the other end portion of the plug having a plurality of resiliently deformable barbs so that it can be readily introduced into a bore whose radius is somewhat smaller than the maximum radius of the barbs whereby the barbs engage the wall of the bores so as strongly to resist withdrawal of the end portion. The strips are cut away adjacent the end of the plug to assist the introduction of said end of the plug into the bore. The outer edge surface of each strip is bevelled to increase the area over which the strips engage the bore. The plug is used for connecting an artificial candle to a base 52 the base having the bore which receives the central part and the strips. The end portion of the plug having the barbs is received in the lower end portion of an elongated cylindrical body and closes said end portion so that the body, the external appearance of which resembles a wax candle, serves as a reservoir for liquid fuel. In the top end portion of the body 10 is a screwed insert 11 which connects a metal wick support device to the body 10. The wick support device comprises a burner 13 and a wick support tube 21 which is connected to the burner 13. The wick 23 extends through the burner and the tube 21 into the reservoir and the tube 21 is provided with a longitudinally extending slot 26 to ease the fitting of the wick. The burner is provided with a groove 33 which receives any fuel spilled from the burner and passes it back to the wick through holes 34. Combustion air is supplied through aperture 32 in the burner so that combustion occurs within a wall portion 30 which cools the flame so that it assumes a yellow colour closely resembling the flame of a wax candle.

Title: Stabilization of beer
IPC: C12H1/044
Filed: 1968-04-27
Abstract: Silica hydrogel useful in the clarification of beer has a surface area of at least 700 m2/g and a mean pore diameter from 30 to 120 A.

Patent ES-354995-A1 (ES)
Title: Shell and tube heat exchangers
IPC: F28D7/16
Filed: 1968-06-14
Abstract: In a tubular heat exchanger in which a high temperature fluid (e.g. hot gas at 2300 F.) flows through tubes 14 from an inlet header 20 defined in part by a tube plate 16, impingement of the hot fluid stream directly on to the tube plate 16 is prevented by a fluid-cooled shield plate 22 positioned in front of the tube plate and so arranged that both sides of the shield plate are subjected to substantially identical pressures. Hence the shield plate can be of relatively thin material and in an apparatus in which the temperature and pressure differences in the heat exchanging fluids are high, the stresses in the tube plate material are reduced. As shown, the shield plate 22 is hollow and cooling fluid is conveyed to and from the plate by way of conduits 34 (only one being shown). The shield plate is spaced from the tube plate 16 and this space 32 may be empty or the plate 16 can be provided with a thin layer ofinsulating or refractory material. Stub tubes 30 extend through the shield plate to convey the hot gas into the heat exchange tubes 14. The peripheral wall of the header is defined by the casing 10 of the heat exchanger and is lined with a refractory material 42 shaped to locate the shield plate. Alternatively the shield plate may be attached to the inner periphery of the shell 10 by a flexible sealing device. The shield plate cooling fluid may be water which is vaporized in the shield plate to provide a useful auxiliary supply of steam. In the event that the external fluid 18 is water some of this may be utilized as the shield plate cooling fluid.

Title: Improvements in or relating to throttle control systems for internal combustion engines
IPC: F02D11/06
Filed: 1968-06-28
Abstract: A pneumatically operated throttle valve control system comprises an engine-driven compressor 11 connected through a branch 12b and manual control valve 17 to the throttle operating cylinder 19 and through a branch 12a and a valve 16 which only opens above a predetermined pressure to a reservoir 15. At starting the compressed air is diverted solely through branch 12b, to give immediate throttle control, until the full operating pressure to which valve 16 is set is reached, where air is also fed to reservoir 15. In a modification a pressure unloader valve in the compressor is controlled by a governor responsive to reservoir pressure and the pipe 12a includes a non-return valve, the pressure from the reservoir 15 reaching pipe 12b through a separate pipe opening into a double non-return valve at the junction with pipe 12b.

Patent ES-432860-A1 (ES)
Title: Pattern dyeing of textile materials
IPC: D06B11/00
Filed: 1974-12-12
Abstract: The work is carried out with at least one row of dye nozzles which extends transversely to the direction of movement of the sheet-like textile structure, which can be a web of carpet material, pressurised jets of dye liquor issuing continuously from the dye nozzles. Each jet of dye liquor is directed either onto the sheet-like structure or away from this according to the pattern to be produced and according to the speed of movement of the sheet-like textile structure. By means of data blocks with pattern data, the selective deflection of each of the jets of dye liquor within successive cycles is controlled. Each cycle is initiated by the movement of the sheet-like textile structure over a distance corresponding to the pattern fineness. Within each cycle, the directing of each jet of dye liquor onto the sheet-like textile structure takes place only during a predetermined time interval which is followed by a rest time. During this rest time, which is at least as long as the recovery time of the dye-liquor jet deflection device composed of the air-supply lines (62) and of the solenoid valves (64), all the jets of dye liquor are directed away from the sheet-like textile structure. The proposed spray-printing process is also suitable for the printing of fine or complicated patterns.

Patent ES-476591-A1 (ES)
Title: A camlock for remote access manipulator.
IPC: F22B37/00
Filed: 1979-01-04
Abstract: This invention relates to a camlock for engaging the inside of tubular members to suspend apparatus from the tubular members. The camlock comprises a movable spacer (154) disposed on a slidable member (152) between two expandable metal rings (158, 160). The relative motion of the spacer and slidable member causes the metal rings to be expanded against the inside of the tubular member thereby supporting the apparatus. The metal rings have a thin wall with internal ribs (202) that fit closely to the slidable member. The internal ribs act as stops (208) on the inside of the metal rings so as to prevent their overexpansion.
