Patent ES-437948-A1 (ES)
Title: Process for the regeneration of spent pickling solutions
IPC: B01D61/54
Filed: 1975-05-28
Abstract: Regeneration of spent hydrochloric acid after use for pickling iron, which therefore contains iron chlorides, by electrolysis in the cathodic and intermediate compartments of an electrodialysis cell. The installation includes electric circuitry for connecting up the anode as well as input conduits for the spent acid but otherwise consists essentially of an electrodialysis cell with an uneven number of compartments wherein each cathodic compartment is separated from the adjacent intermediate compartment by an anion-selective membrane while a cation-selective membrane separates each intermediate compartment from the anodic compartment, the latter being filled with an anolyte whose total Faraday yield for water oxidation is close to 1. Electrolysis is conducted with current densities at the cathode of 0.1 - 20 A/dm2, at the anode corresponding to the water oxidation reaction and at the membranes such that their perm-selectivity is close to 1. The ionic strengths in equivalents of the regenerated solution and of the untreated spent acid are the same.

Title: Apparatus and process for the production of gluten and starch from wheat, rye, or barley
IPC: A23L7/10
Filed: 1977-03-11
Abstract: Apparatus and method for producing gluten and starch from a dispersion of wheat, barley or rye endosperm fractions in water. The raw grain is initially milled to produce endosperm fractions suitable for carrying out the subsequent steps of the process. The steps taken in the milling process include breaking the raw grain between a series of fluted rollers, sorting the bran from various grades of semolinas, sizing coarse semolinas by the cutting action of fluted, opposed rollers, pressing and impacting coarse and fine semolinas by a series of smooth, opposed rollers and dissipaters, and finally reducing the tailing from the pressing and impacting steps in a series of smooth or fluted rollers, and dissipaters.
Patent ES-461363-A1 (ES)
Title: Self energizing brake assembly
IPC: F16D49/20
Filed: 1977-08-04
Abstract: A brake assembly for engaging the periphery of a rotatable member, the brake assembly being energized by rotation of the rotatable member in either direction. The brake assembly includes a movable brake shoe which may be forced into contact with the periphery of the rotating member. The brake shoe has spaced apart rollers which are held in engagement with converging ramps on a wedge block. The brake shoe is permitted to shift laterally with respect to the ramps, and as the brake shoe engages the rotating member one of the rollers will move downwardly along one of the ramps to affect self-energization of the brake shoe. The wedge block is provided with a downwardly extending projection which is disposed between the converging ramps, the projection being received within a recess formed in the brake shoe, the recess being of greater width than the projection. The recess and projection limits the lateral shifting of the brake shoe which takes place during self-energization and permits disengagement of the brake shoe even when a lateral shifting force is being imparted to the brake shoe by the rotatable member which would normally cause further self-energization.
Patent ES-463672-A1 (ES)
Title: Seismic investigation of underwater geological formations - using bubble-noise-suppressing, air-cannon acoustic source at shallow depths
IPC: G01V1/387
Filed: 1977-10-27
Abstract: Acoustic signals for seismic exploration are generated by allowing compressed gas to escape at a predetermined depth in a volume of water. The first emitted sections of the acoustic signals are amplified and the later emitted sections are damped by echo signals derived from the generated signals and reflected from the surface of the water, whilst the acoustic signals derived from the generated signals and propagated through the ground formations beneath the water are detected. Specifically, during generation, acoustic signals are originated at a predetermined depth. This has the result that twice the acoustic transmission time from the depth to the surface of the water, is about equal to the duration of the first half cycle of the first emitted section of each signal generated. The signals are generated at a depth of pref. 1.50-4.50 m, esp. 3m beneath the surface of the water. Method overcomes problems of bubble oscillation, and provides a means of transmitting considerably improved signals from an underwater acoustic source.

Title: Method and apparatus for continuously forming an airlaid web.
IPC: D04H1/72
Filed: 1978-12-19
Abstract: A continuous in-line method for forming an airlaid fibrous fluff web adjacent the uppermost and lowermost surfaces of a substantially planar internal reinforcing ply having substantially the same width as said fibrous web, said ply being substantially impervious to the passage of fibers from one surface thereof to the other, in a continuous fiber deposition zone is disclosed. In a preferred embodiment, a unique tissue folding board is employed to permit continuous formation of an airfelt web having a wet strength tissue reinforcing member located approximately mid-way between its uppermost and lowermost surfaces. In the apparatus for forming the web, two adjacent vacuum chambers (26,27) are preferably employed in the continuous forming zone to compensate for the increased airflow restriction encountered when forming the uppermost fibrous web position over the reinforcing ply and the lowermost fibrous web portion. In a particularly preferred embodiment, the portion of the internal ply (20) relative to the uppermost and lowermost surfaces of the resultant pad may be adjusted by advancing or retarding the position of the folding board (1) within the fiber deposition zone (12).
Patent ES-476777-A1 (ES)
Title: Dual media filter
IPC: B01D39/08
Filed: 1979-01-11
Abstract: As exemplified by an automobile engine oil filter, the usual pleated filter paper is internally supported by an interpleated layer of high tear and tensile strength material which is substantially more flexible than the paper. With the ends of both layers anchored conventionally in the element's end caps rigidly held apart by the usual perforated center tube, the flexible material is subjected to a tensile stress when the paper attempts to move inwardly, the paper being thereby supported against rupturing or pleat tear. The flexible material thus functioning as a back-up layer for the paper, can be pretensioned to provide greater additional resistance to inward movement of the paper.

Title: Method and apparatus for testing enclosed electromagnetic relays.
IPC: G01L5/00
Filed: 1979-11-22
Abstract: Method and apparatus for testing enclosed electromagnetic relays (14) includes a probe (17) displaceable into the relay enclosure to engage the movable contract (14b) thereof. The probe is associated with a force transducer (16) and a displacement transducer (20) which provide inputs to a circuit including microprocessor unit, which operates to detect the probe force required to break contact between the movable contact (14b) and the normally closed contact, and to detect the position of the probe when such break occurs and when the normally open contact is made and to calculate the contact travel from the position signals it receives. Contact over travel is also measured by applying current to the relay winding and measuring probe displacement required to re-engage the contact.
Patent ES-486269-A1 (ES)
Title: Gear Box with Lubricant Evacuation System
IPC: F16N31/00
Filed: 1979-11-23
Abstract: A gear housing encloses a gear train and contains an integral oil reservoir 70 which keeps the quiescent oil level above the bottom gears 30 and 32 in the train and includes a passageway 62 with a bottom opening enshrouding the gear 32 at the bottom of the housing. Rotation of the bottom gear above a certain tooth tip velocity causes viscously dragged oil to be directed by a lip 64 on the passageway into the passageway and vertically upward to an opening 68 which allows the oil to drop into a dammed reservoir 76 from which part feeds back to the gear train while the majority of the oil returns over the dam 78 to the reservoir. Thus, when excessive oil is evacuated from the gear train, the oil will cascade over the dam to the reservoir so as to provide a predetermined maximum volume of oil gravity-fed back to the gear train.
