Title: Process for treating air-borne (metallic) dusts containing silicon dioxide to form precipitated silicic acids and silicates
IPC: C01B33/32
Filed: 1977-02-28
Abstract: There is provided a process for treating air-borne dust containing silicon dioxide in order to form a silicic acid or a silicate. The air-borne dust is dissolved in an alkali metal hydroxide solution to form an alkali metal silicate solution. The alkali metal silicate solution is purified by treating it with activated charcoal and/or oxidation agents. Non-decomposable substances remaining after the purification step are removed from the alkali metal silicate solution. The alkali metal silicate solution is then reacted with acids and/or salts of aluminum, magnesium and calcium. The resulting product is then filtered, washed and dried, and then comminuted to form a finely divided, amorphous, substantially pure, precipitated, silicic acid or silicate having a whiteness according to Berger at a wave length of 460 m mu of about 90 to about 95% and a specific surface area of about 30 to about 800 m2/g BET.

Title: Apparatus for producing plates and similar articles
IPC: B28B7/44
Filed: 1977-06-14
Abstract: The rigid top pressing punch of a press for producing plates or the like is shaped in accordance with the inner shape of the plate or the like to be produced. An elastic membrane, which establishes the top boundary, i.e., closes the cavity of a mold, is held at its edge shaped to the dimensions of the eventual plate, and is provided with an annular groove corresponding to the foot of the plate. Pulverulent porcelain composition is distributed on the membrane in the area determined by the edge having the holding action structure. The cavity defined by the membrane is filled with a pressure medium. After lowering the pressing punch, pressure can be applied through the pressure medium to the pulverulent porcelain composition distributed on the membrane in a pressing position. The elastic membrane in its relaxed position corresponds to the shape of the lower surface of the plate or the like, is made with an even, minimum thickness over substantially its whole area and has sufficient inherent strength. It can be deformed into a filling position for filling and can be returned into its relaxed starting position during the pressing operation by causing hydrostatic pressure to act against its lower surface.

Title: Fault locating apparatus for digital transmission system
IPC: H04L1/24
Filed: 1977-06-14
Abstract: Defective repeaters in a multihop, digital microwave transmission system are located by the use of a special test pattern which is generated at the transmitting terminal. At each repeater station, the two outputs of the phase demodulator are compared to determine if the test pattern has been properly received from the upstream repeaters. The special test pattern, S, has the characteristic that S = S(2N) that is to say, the test pattern equals the complement of itself delayed by 2N symbols. This special characteristic makes it unnecessary to employ a differential decoder in the test apparatus at each repeater station.

Patent ES-475502-A1 (ES)
Title: Method of making a fastener strip
IPC: B21K1/66
Filed: 1978-11-28
Abstract: A strip of fasteners such as pierce nuts is formed from a metal blank with no scrap resulting from the provision of a spacing between adjacent nut bodies, and without the difficulty and expense incident to attaching nut bodies to connecting elements. The body portion of a laterally flanged blank is severed in the transverse direction to separate nut bodies from the blank without fracturing the flanges. The flanges are severed in the longitudinal direction to form severed longitudinally extending flange segments integral at both ends with unsevered flange segments. When the flanges are straightened, the stretching of the severed flange segments resulting from shearing provides a spacing between adjacent nut bodies in the strip. The strip includes spaced apart nut bodies interconnected by continuous lateral flanges. The flanges include unsevered lateral flange segments integral with both sides of each nut body, and severed flange segments integral at both ends with the unsevered flange segments. Elongation of the severed flange segments provides spacing between adjacent nut bodies.

Patent ES-8206008-A1 (ES)
Title: Boiler tube silencer
IPC: F22B37/40
Filed: 1981-02-18
Abstract: Non-contact heat exchangers comprise a gas carrying duct which has fluid carrying tubes inserted therein so that hot gas may heat the tube fluid. This simple principle is extrapolated into a heat recovery steam generator for a combined cycle power plant where hot gas turbine exhaust gases are used to heat steam turbine feed water in order to produce steam. A noise/vibration problem may be generated at certain gas turbine loads which create stimulus frequencies at or near boiler tube response frequencies. The invention proposes an optimum arrangement of upstream baffles which suppress the stimulus frequency generated by the gas flowing through the duct.
