Patent ES-455456-A1 (ES)
Title: Photographic type composing machine
IPC: B41B27/02
Filed: 1977-01-28
Abstract: The machine provides access to a relatively large number of different characters located on relatively large spinning discs or drums. The characters are located in arrays such as concentric rows on a disc. A plurality of lenses is mounted on a lens carriage, and one or more light sources is mounted on a flash-lamp carriage. Character spacing is determined by motion of the lens carriage and/or the lamp carriage. Array selection is performed by motion of the lamp carriage, and/or motion of the lens carriage. Composition of lines or columns of characters taken from a relatively large number of different arrays, such as would be the case in type composition using Chinese ideographs, is speeded considerably by controlling the order in which the characters are projected so that the lens carriage need not reverse its direction of motion during composition of a line. A simple mechanism is used to change lenses for size changes by the selective use of stops at the ends of the travel path of the lens carriage. Two discs or drums can be used alternatingly to increase the number of characters available. A simple attachment is provided for composing long lines of enlarged characters for composing headlines and the like. This avoids the necessity of providing a separate headlining machine. Another simple attachment is provided for inserting Pi characters. This attachment makes use of the lamp carriage and drive mechanism in selecting the Pi characters for projection. A method which is especially useful in economically producing large matrix discs is described. An economical "floppy" or flexible film disc also is described. A system and method are described for electronically detecting base-line and spacing errors in the characters on the character matrix, storing the errors, and correcting the errors electronically during projection of the characters onto the photographic film.

Title: Anti-pump circuit breaker
IPC: H02H7/22
Filed: 1979-02-13
Abstract: The circuit breaker is taught with an anti-pumping control circuit. If the circuit breaker closes on a fault and quickly reopens without the closing switch being either mechanically or electrically released in the interim, reclosure of the circuit breaker either by an automatic reclosure or by the mere fact that the closing switch remains closed will be prevented until the closing switch is once again opened. In addition, if the closing switch is actuated prior to power being applied to the circuit breaker control system, the circuit breaker will not close when power is applied. The closing spring will be charged, however, for a subsequent circuit breaker closing after release and reactuation of the closing switch.

Patent ES-487108-A1 (ES)
Title: Method for applying a protective film to a plastic profile and plastic profile coated with a protective film.
IPC: B05D7/02
Filed: 1979-12-20
Abstract: A flexible plastic profile manufactured by extrusion is to be protected by a plastic film which adheres so well to a surface that it remains free of folds and on the other hand can be easily pulled off later. These conditions should also be easily maintained if different profile materials of different adhesive properties from those of the material of the protective film are used. This is possible firstly since the protective film material is applied to the extrusion-warm plastic profile. Secondly, a mixture of two thermoplastic components is used to form the protective film, of which components the one has weak adhesive properties with respect to the profile material and the other strong adhesive properties and their mixing ratio can be easily changed according to the adhesive properties of the plastic profile.

Title: Method for the preparation of a cellular foamed body of a vinyl chloride-based resin
IPC: C08J9/14
Filed: 1980-04-30
Abstract: The invention provides a novel and improved method for the preparation of a cellular foamed body of a vinyl chloride-based resin having a very fine and uniform cellular structure with high productivity in a continuous process. According to the inventive method, a vinyl chloride-based resin is admixed with a nucleating agent and a foam conditioning resin which is a specified acrylic resin or a styrene-based resin into a resin composition and the resin composition is first heated under pressure to be converted into an at least partly gelled mass, into which a volatilizable foaming agent which is an organic solvent having a boiling point not exceeding 90 DEG C. is injected under pressure so as that the resin composition is uniformly impregnated with the foaming agent. The foaming agent-impregnated and completely gelled resin composition is then brought under a reduced pressure to be expanded into foams with simultaneous cooling. The above process is most conveniently practiced by use of an extruder machine in which the volatilizable foaming agent is continuously injected into the cylinder where the heated and gelled resin composition is running.

Title: Controlled short residence time coal liquefaction process.
IPC: C10G1/00
Filed: 1981-04-02
Abstract: Normally solid dissolved coal product and a distillate liquid product are produced by continuously passing a feed slurry comprising raw feed coal and a recycle solvent oil and/or slurry together with hydrogen to a preheating-reaction zone (26, alone, or 26 together with 42), the hydrogen pressure in the preheating-reaction zone being at least 1500 psig (105 kg/cm2), reacting the slurry in the preheating-reaction zone (26, or 26 with 42) at a temperature in the range of between about 455 DEG and about 500 DEG C. to dissolve the coal to form normally liquid coal and normally solid dissolved coal. A total slurry residence time is maintained in the reaction zone ranging from a finite value from about 0 to about 0.2 hour, and reaction effluent is continuously and directly contacted with a quenching fluid (40, 68) to substantially immediately reduce the temperature of the reaction effluent to below 425 DEG C. to substantially inhibit polymerization so that the yield of insoluble organic matter comprises less than 9 weight percent of said feed coal on a moisture-free basis. The reaction is performed under conditions of temperature, hydrogen pressure and residence time such that the quantity of distillate liquid boiling within the range C5-455 DEG C. is an amount at least equal to that obtainable by performing the process under the same conditions except for a longer total slurry residence time, e.g., 0.3 hour. Solvent boiling range liquid is separated from the reaction effluent and recycled as process solvent.
