Title: Process for the preparation of aryl-substituted normal paraffin hydrocarbons
IPC: B01J23/00
Filed: 1968-11-14
Abstract: Linear detergent alkylate is produced by a process comprising the steps of (a) catalytically dehydrogenating an n-paraffin feed in the presence of hydrogen, (b) using the resulting monoolefins to alkylate a monocyclic aromatic, particularly benzene though others are mentioned, (c) separating the alkylation zone effluent to produce required product and an unchanged n-paraffin fraction for recycle to (a), and (d) before said recycling, treating at least part of the n-paraffin fraction to remove non-normal hydrocarbons therefrom such that the concentration of n-parafhns in the n-paraffin fraction is at least 90 wt. per cent.

Patent ES-409158-A1 (ES)
Title: Continuous flow hydrofoil configuration
IPC: B63B1/30
Filed: 1972-11-30
Abstract: A hydrofoil support arrangement for a hydrofoil boat incorporating a water jet propulsion ducting mechanism for foil-borne and hullborne operations. The arrangement employs a hydrofoil strut assembly which is pivotally mounted to the boat for pivoting the assembly to a foil-submerged or foil-emerged position. The foil strut assembly utilizes a center strut or column which has a first inlet and internal duct for feeding water to the propulsion means during foil-submerged conditions. A second hull inlet in the duct is provided which opens upon foil-strut retraction, thus replacing the first inlet so that continuous water input at the foilborne and hull-borne operations is maintained. The foil strut overall assembly adds to structural strength, and the outer struts act as efficient end plates to the lifting foil surfaces thereby reducing the tip vortex formation and increasing the system efficiency.

Title: Tape cartridge having enhanced tape drive facilities
IPC: G11B15/18
Filed: 1976-08-16
Abstract: A tape-containing cartridge accommodates an endless tape either in the form of random loops or in the form of a tape roll wound on a single reel. A tape passageway extends the cartridge from a cavity adjacent a back wall, thence between a first side wall and a first internal wall past pad means and thence between a front wall and a second internal wall past a transducer-receiving opening formed in the front wall and thence between a pinch roller and portions of the front and second side walls into the cavity.

Title: Improvement regarding discharge electrode for electrostatic dust collector
IPC: B03C3/41
Filed: 1978-12-07
Abstract: Ionising electrodes consist of a rigid tube to which are fixed peripheral projections which diffuse or distribute the emissions of the electrode. The projections may take several forms but are always rounded at the ends. The projections are oriented parallel to the course followed by the gaseous current in an electrostatic precipitator. The arrangement of projections produces an equilibrated emission of ions by the extremities which much reduces the risk of electric discharge. The rounded extremities are only slightly exposed to corrosion due to electric erosion and are mechanically very stable. The electrode is robust and simple.
