Patent ES-428124-A1 (ES)
Title: Process and apparatus for preheating solid particulate materials
IPC: F27B1/10
Filed: 1974-07-10
Abstract: A method and apparatus for preheating solid particulate materials such as limestone and materials used in the process of making sealed surface lightweight aggregate. It includes a vessel having an inlet for solid particulate material and an outlet for solid particulate material, an inlet for hot gases and an outlet for gases. A preheating zone is defined by a bridge, the floor of the vessel and the vessel sidewalls. A valve arrangement is provided for controlling the length of the gas flow path through the preheating zone. When the valve is in one extreme position, the flow path through the gas-solids contact zone is the longest, and when the valve is in the other extreme position, the flow path through the gas-solids zone is at its shortest. The position of the valve may be controlled in response to either the pressure drop across the preheating apparatus or the temperature of the material discharged from the preheater.
Patent ES-429025-A1 (ES)
Title: Damped support screen for catalytic converter
IPC: F01N3/28
Filed: 1974-08-07
Abstract: Support screens for retaining particulate catalyst in a catalytic converter are made highly resistant to fatigue failure which is caused by vibration from exhaust gas pulses. The screens are strengthened by welding formed support wires at a single center point to the downstream face of each screen. The wires are integral with the screen only at its center. Other portions of the wires are positioned in recesses in the housing walls where they prevent axial movement of the screens. The portions of the wires within the recesses are free to expand or contract independently of the material of the screen. The limited degree of connection between the wires and a screen prevents the wires and screen, which have different natural frequencies, from vibrating as a composite unit. Furthermore, any tendency toward separate vibration of the wires and screen is damped due to the contact between the wires and screen. By embossing the screen at its center and placing a metal disk on the side of the wires opposite the screen it is possible to use high energy discharge resistance welding techniques to achieve a screen-support composite having much greater deflection resistance than is possible by ordinary welding.

Patent ES-441395-A1 (ES)
Title: Method of and apparatus for adjusting electrical chokes
IPC: H01F41/00
Filed: 1975-09-30
Abstract: The method allows iron-core inductors to be produced with an inductance which is subject to tight tolerances. The adjustment (trimming) which is required for this purpose has been carried out, in the case of inductors having two core stacks which can be displaced with respect to one another within tight limits, with the aid of a pressure-loaded roller by means of which the core stacks were displaced with respect to one another on a sufficient part of the length of the inductor, and the air gap was thus reduced. This adjusting (trimming) principle is now used in conjunction with an inductor (6) having an E/I-shaped jacket core in that the I-shaped stack is permanently bent on a part of its length.

Title: Shuttleless loom with at least one weft thread carrier
IPC: D03D47/24
Filed: 1976-12-28
Abstract: The weaving machine has a guide (4) for one or more weft-thread grippers (3), which extends through the shed and which forms a continuous path.

Patent ES-475158-A1 (ES)
Title: Fluid laser flow channel liner
IPC: H01S3/213
Filed: 1978-11-16
Abstract: A fluid laser having a flow channel between fluid inlet and active lasing region which reduces medium heating and resulting medium disturbances. The channel includes a thin optically transparent, thermally insulating layer directly bordering the medium. The thin layer rests upon a metallic heat sink, typically cooled, which receives and removes radiated energy from the active region, preventing it from heating the medium. The thin insulating layer permits the heat sink to be cooler than the medium without causing thermal effects in the medium. The more homogeneous medium resulting from such treatment contributes to better laser beam quality.
