Patent ES-469571-A1 (ES)
Title: Core of nuclear reactor
IPC: G21C5/00
Filed: 1978-05-08
Abstract: A nuclear reactor core for power generation comprises fuel element assemblies which are shuffled from one region of the core in one operating cycle to a different region in the next operating cycle. The assemblies at positions remote from the neutron flux gradient have lower reactivity than the remaining element assemblies. Pref. individual fuel rods of an assembly have reduced reactivity compared with the other rods. In polygonal core where the assemblies are square in plan, the fuel element assemblies near the periphery in the first operating cycle contain fuel rods of reduced reactivity. Pref. these rods are located at the outer corners of the fuel assemblies. The arrangement is intended for improved utilisation of the rod for a given peak temperature in the core. The reduced reactivity may be obtd. by incorporating a neutron poison, pref. a poison which becomes consumed. A rod may contain only neutron poison and no fissile material.

Patent ES-8102914-A1 (ES)
Title: Switch set for a keyboard.
IPC: H03K17/975
Filed: 1980-03-31
Abstract: An electronic switch keyboard for typewriters or office machines includes a multiple switch at selected key positions to provide two signal inputs to a utilization device. A first capacitor switch is actuated to provide a first signal upon initial key depression and a second contact switch, common to all selected key positions, is actuated to provide a second signal upon further key depression at the selected key positions. A ground plane forms a portion of the contact switch and further serves to reduce parasitic capacitance and to shield the capacitive switches from stray electrical noise occasioned by the contact switch or other electrical inputs. A dielectric material is used to accurately separate the ground plane from the capacitive switch and further serves as a force spreading device for the contact switch. When the keyboard is used in conjunction with a typewriter, the first signal may be used to effect character selection and printing and the second signal to effect repeated printing of the same character. Consistent with prior mechanical typewriter keyboards, three increasing levels of force are required to be overcome as the key is depressed: a pretravel force, a first switch actuation force, and a second switch actuation force.

Title: Process for coating reactors using organic compound vapor application.
IPC: C08F2/00
Filed: 1980-09-12
Abstract: This invention relates to the reduction of polymer buildup on the inner surfaces of a polymerization reactor by applying a polymer buildup resistant coating to the inner surfaces thereof, the method or process of applying said coating being the subject of this invention. An approximate monolayer coating on the inner surfaces of the reactor results from applying thereto an aqueous or organic solvent solution of the coating material by means of a hydrocarbon gas, such as propane, for example. The coating material is an organic compound or polymer which is capable of resisting polymer buildup thereon. As examples of such coating materials, there may be named the polyaromatic amines, self-condensed polyhydric phenols, tannic acid and tannates, various dyes, such as nigrosine, and the like, etc. When using hydrocarbon gas to apply the coating material, the same reaches the inner reactor surfaces in the form of a mist. When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH2=C< grouping, and mixtures thereof, in the presence of said coating, polymer buildup on the inner surfaces of said reactor is substantially eliminated.

Filed: 1981-11-11
Abstract: An optical display cell of the liquid crystal type has two parallel substrates separated from each other by means of ball-shaped monodisperse particles, which are distributed homogeneously and separately across the entire area of the substrate. The dimension of an intermediate layer of liquid crystals between the substrates is, therefore, determined by the diameter of the particles. The particles are distributed across the substrate in a room, which is shielded against dust and foreign particles, by means of pressurized gas, which creates turbulence in the room. The ball-shaped particles are distributed homogeneously across the entire area of the substrate.

Patent ES-8403185-A1 (ES)
Title: Pool cleaning device for rolling operation under pool cover.
IPC: E04H4/12
Filed: 1982-10-08
Abstract: A positive buoyancy programmed motion pool cleaning device is adapted for rolling operation under a floating pool cover so that encountered cover discontinuities such as folds, borders and tears do not interrupt and stop the operation of the device. The pool cleaning device is of the type that has two positive buoyancy portions, these portions typically being positioned fore and aft. At least one and preferably two inverted casters are utilized, the casters each preferably becoming the positive buoyancy portion of the cleaning device. Overall positive buoyancy of the cleaning device causes the caster to ride on the overlying cover at the cover pool interface. The caster is provided with a fairing to reduce drag. A ramp at the leading end of the caster on the upward edge of the inverted fairing allows encountered cover discontinuities to pass smoothly over the fairing to the upwardly exposed caster. The constraint of the overlying pool cover to cause increased tendency of the pool cleaning device to foul pool obstructions, such as ladders and gutter mounted devices, is avoided by providing a housing between the respective casters and a wheel around the rear caster.

Patent ES-8505026-A1 (ES)
Title: Reciprocating piston internal combustion engine
IPC: F02B37/013
Filed: 1984-08-17
Abstract: A piston internal combustion engine in which for the engagement and disengagement of an exhaust gas turbocharger (12), its exhaust gas closure device (33) is opened, respectively, closed only so far that the charging air pressure produced by the continuously engaged exhaust gas turbocharger (11) remains approximately constant. By re-routing a small air quantity by way of a by-pass line (36) to the suction side of the compressor (24), the power input of the compressors (21 and 24) is kept small. During the engagement of the exhaust gas turbocharger (12), a small energy quantity is therefore sufficient in order to accelerate the same to its operating rotational speed. Thereafter, the engaging operation is terminated by complete opening of the exhaust gas closure device (33) and by opening of the charging air closure device (34).
