Title: Pouring ladle and pouring platform car for use therewith
IPC: B22D41/12
Filed: 1973-07-20
Abstract: A pouring ladle and a platform car for use therewith are disclosed, the aforesaid ladle having a partition wall therein which has a passage adjacent to its bottom for allowing the communication of the melts separated by said wall, said wall being positioned in said ladle between the inclining center, i.e., a fulcrum of said ladle and the center of gravity of the melt contained therein, thereby suppressing a wave-forming phenomenon accruing from the inclinging movement of the ladle, with the resultant smooth pouring operation. This ladle is mounted on a frame body of a platform car in a manner to permit its inclination toward a casting mold, said platform car being capable of travelling in synchronism with the speed of a mold conveyor and adapted to move in the direction toward the casting mold, thereby presenting improved efficiency for casting operation, coupled with improved safety.

Title: Digital multi-line companded delta modulator
IPC: H03M3/02
Filed: 1977-06-28
Abstract: A companded digital delta modulator which can encode both voice and voice band modem signals over a wide range of input levels is shown. The companding method or algorithm is based on measuring bit stream correlation and can be scaled to give substantially maximum performance over a wide range of signal types. The algorithm has a low sensitivity to digital channel errors, thus making it suitable for signal coding for satellite channels and the like. In addition, the digital design permits common hardware to simultaneously serve a large number of lines, thus permitting the substantial savings in the hardware cost per line. A further aspect of the invention concerns the ability to handle multiple bit delta modulation as well as single bit delta bit modulation in the above environment.

Patent ES-460891-A1 (ES)
Title: Water-soluble reactive azo dyestuffs
IPC: C09B62/008
Filed: 1977-07-20
Abstract: The new reactive dyes have the formula < IMAGE > where D is the radical of an aromatic carbocyclic or heterocyclic diazo component, R is optionally substituted alkyl, R1 is hydrogen or optionally substituted alkyl, B is a bridge member or a direct bond, and X is a reactive group. These dyes are obtained by combining diazotised amines of the formula D-NH2 with an appropriate coupling component. A further process for preparing the dyes of the formula I where B is a direct bond involves reacting the diazotised amines of the formula D-NH2 with a compound of the formula < IMAGE > to form corresponding dyes, which, by elimination of Y-H, are then reacted with reactive components to introduce the radical X. Starting from the diazotised amine D-NH2 and reacting with a dye of the formula III containing the bridge member B and likewise reacting with a reactive component to introduce X gives the corresponding new dyes. The dyes obtained can be used for dyeing and printing hydroxyl- or amido-containing textile fibres, yarns and fabrics.

Title: Method of and apparatus for the degasification of circulation systems for liquids
IPC: F24D19/08
Filed: 1979-03-09
Abstract: In a closed circulation system containing a constant amount of liquid, a force is generated for driving the liquid through the system.

Patent ES-8307543-A1 (ES)
Title: Coating apparatus and process.
IPC: B05D1/34
Filed: 1982-01-20
Abstract: Production of a longitudinally striated coating on a strip article by advancing the article past an open side of an otherwise-enclosed trench so that the article surface to be coated closes the open trench side, while delivering concurrent laminar flows of two different liquid coating materials to the trench at least at one locality spaced from the trench open side, to keep the trench completely filled and to deposit a layer of coating material on the moving article surface. Liquid circulation in the trench caused by the motion of the article surface so distributes the two coating materials along the trench that the applied coating layer is constituted of alternating longitudinal striations of the two materials. With delivery of concurrent flows of the two coating materials at each of plural localities spaced along the trench, positional and other variations of the striations can be achieved by varying the relative total flows delivered at different ones of these localities, for example to create a simulated wood-grain pattern.

Title: Increasing water prodn. rate of wells
IPC: E03B3/15
Filed: 1982-02-12
Abstract: Water discharge from drilled wells increased by introducing into the filter section of the well a weak acid of dissociation constant below 0.001. After a period of 10-48 hr, with the well under pressure, the well is flushed using a scavenging pump. A soln. of NaHCO3 and/or NACL is then introduced into the filter and after a further period of 1-36 hr. the well is again flushed using the scavenging pump. Pref. acids are acetic, tartaric, citric or metaboric and/or tetraboric acid. - The method can be applied to old wells and to newer wells in which mud has collected. The treatment increases the permeability of the rock formation and avoids the problems (corrosion and layer collapse) associated with use of hydrochloric acid. USAB- US4541488 A Water discharge of a drilled well previously used for water delivery and having decreased water discharge, is increased by (a) introducing a weak acid of dissociation constant less than K(D) = 0.001 for 10-48 hrs. under pressure into a filter section of the well; (b) flushing the filter section using a scavenging pump to remove acid; (c) introducing basic sodium bicarbonate and/or -hypochlorite soln. into filter sections for 1-36 hrs.; and (d) flushing the filter section as in (b) to remove basic soln. - Pref. acid comprises acetic-, tartaric-, or citric acid; or metaboric and/or tetraboric acid.
