Patent ES-464778-A1 (ES)
Title: Method of dividing articles in sheet form to produce portions of predetermined shape
IPC: A24C1/04
Filed: 1977-12-06
Abstract: Pieces of a flat starting material, for example tobacco leaves, are arranged on a carrier (1), the surface of these pieces is scanned by a beam (3) of electromagnetic rays and the electromagnetic rays reflected or transmitted by the material are received by a sensor element (4). The sensor element (4) generates, in dependence on the intensity of the received radiation, an output signal which permits the edges of the material pieces and any faults, such as holes, in these pieces to be recognised and serves to control the cutting out of the parts in such a manner that the latter are cut out only within the edges of the material pieces and have a minimum of faults.

Patent ES-468080-A1 (ES)
Title: Internally coated reaction vessel for use in olefinic polymerization
IPC: C08F2/18
Filed: 1978-03-20
Abstract: This invention relates to a polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto a coating composition containing, as a primary ingredient, (1) the self-condensation product of a polyhydric phenol, or (2) the condensation product of two or more polyhydric phenols, or (3) the self-condensation product of a polyhydric naphthol, dissolved in an aqueous alkali metal hydroxide solution. When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH2=C< group, and mixtures thereof, in the presence of said coating, polymer build-up on the inner surfaces of the reaction vessel is substantially eliminated. Further, multiple charges or batches of polymer can be made in said internally coated reaction vessel without opening the same between charges thus preventing the escape of unreacted monomer to the surrounding atmosphere.
Patent ES-475132-A1 (ES)
Title: Method and apparatus for impregnating base material of match
IPC: B27K3/02
Filed: 1978-11-16
Abstract: The basic material for matches i.e. the matchsticks are impregnated by introducing the sticks into the end of a rotating drum. The impregnation agent is introduced as a spray onto a falling curtain of matchsticks created as the drum rotates. The impregnating agent is virtually completely absorbed before the match sticks are discharged from the drum. The impregnation agent is sprayed near the inlet and for the matchsticks and the absorption process occurs as they move through. For impregnating matchsticks with after burning inhibitor. The process takes less space than conventional wetimpregnation and does not cause the matchsticks to stick together as in dry impregnation.
Patent ES-475336-A1 (ES)
Title: Low sport shoe
IPC: A43B5/00
Filed: 1978-11-23
Abstract: A shoe having a sole, an upper formed from a relatively soft and extensible material, a lacing strip and a bandage connecting the lacing strip with the sole. The bandage is formed from a material which is less extensible than the material of the upper. The bandage includes an elongated portion and a connecting portion which extends laterally of the elongated portion at the juncture of the bandage with the lacing strip. The laterally-extensive connecting portion transmits forces from the lacing strip to the elongated portion, and substantially prevents transmission of such forces through the extensible material of the upper. Thus, the upper is less apt to become fatigued or distorted during wear. This abstract should not be taken as a complete exposition of the present invention.

By using such transfer sheets, designs can be printed which are not otherwise obtainable by conventional techniques. The invention further concerns the method of making such sheets, their use in the printing of various materials, and the materials which have been so printed.

Patent ES-480169-A1 (ES)
Title: Method and apparatus for acoustic signal detection
IPC: G01V1/50
Filed: 1979-05-02
Abstract: The disclosure relates to a method and apparatus for acoustic signal detection, adapted for use in acoustic velocity well logging to measure the difference in transit times of an acoustic signal between a transmitter and two or more receivers. In a preferred embodiment of the present invention two timing measurements of the signal R1s, R2s arriving at each of two receivers (R1, R2 Fig. 1, not shown) may be made by activating zero crossing detectors at the arrival of the first negative and first positive half- cycles at each receiver. A transit time is calculated from the zero crossing times following the first negative half-cycle. This first transit time A'-A may be checked for accuracy by comparing the first transit time with a second transit time B'-B calculated from zero crossing times following the first positive half-cycles, by comparing the first transit time to a previously measured transit time and/or by detecting the order of arrival of the negative and positive half-cycles to determine whether the half-cycles have been detected out of sequence at either receiver. Should the first transit time be determined to be inaccurate, the previously measured transit time or the second transit time may be substituted therefor.

Title: Process for automatically controlling the detoxification of waste waters containing nitrite ions
IPC: C02F1/72
Filed: 1979-11-19
Abstract: In the detoxification of waste waters containing nitrite ions by means of hydrogen peroxide the addition of hydrogen peroxide is automatically controllable by adding the hydrogen peroxide continuously or in portions with continuous measurement of the pH and stopping the addition when no further reduction of the pH is caused by it. By control of the hydrogen peroxide addition through the change of the pH it is guaranteed that sufficient hydrogen peroxide is added to reach a complete detoxification of the waste water while on the other hand there is not wasted hydrogen peroxide unnecessarily.
Patent ES-8101298-A1 (ES)
Title: Method of editing or cross-fading without interfering noise, two digital signal sequences, particularly of audio signals.
IPC: G11B27/038
Filed: 1980-03-28
Abstract: A method is disclosed for the joining or mixing-in or fading of two program segments which appear in the form of digital pulse sequences, free of interfering signals, particularly audio signals digitally stored on magnetic tape, whereby code word sequences which are present in both signal segments in the region of an editing location or fading location are scanned, together with their associated time codes, and are fed to respective intermediate memories. Then, by an acoustically-monitored cyclical circulation of the contents of the intermediate memories, controlled in frequency and direction, an editing location of comparable information for each program segment is determined which is free of interfering signals. A transition, controlled by the time codes is then occasioned from the first signal segment to the second signal segment or a fading of the second signal segment is occasioned relative to the first signal segment. The two time codes which are associated with the editing locations are read for carrying out a mechanical and/or electrical connection of two signal program segments which are acoustically free of interfering signals at the proper time corresponding to a common edit point identified by the two time codes.

Patent ES-8701357-A1 (ES)
Title: A gas turbulator.
IPC: F23C6/04
Filed: 1985-04-10
Abstract: A gas turbulator (21) is used in burners (20) of different kinds to obtain better combustion. The turbulator is placed in a chamber or passageway (10) for hot combustion gases. The turbulator fills the passageway forcing the gases to pass a double-walled unit comprising a first membrane wall (22) with radial slits (24) and another membrane wall (23) with a central exhaust opening (26). An expansion nozzle (27) is connected to this opening (26). The slits (24) have oblique wings (25) at least along one edge, which causes the gases to mix intensively within the space between the membrane walls (22, 23). These are during burning maintained at a high temperature, which garanties an efficient final combustion.
