Title: Process for the preparation of a catalyst and its application to the polymerisation of 1-olefins.
IPC: C08F10/00
Filed: 1979-01-17
Abstract: A catalyst for the polymerization of 1-olefins is prepared by successively applying a chromate ester and a titanium ester to a carrier containing silicon dioxide, in the absence of an unsaturated polymerizable hydrocarbon, and activating with an aluminum-organic compound. In the manufacture of the catalyst no washing liquids are obtained from which metal compounds would have to be separated. In the presence of hydrogen the catalyst gives a high yield of polymers with broad molecular weight distribution and a small content of high molecular constituents. The films made therefrom are practically free from specks.

Title: Process for cross-linking carboxymethyl cellulose and products obtained by this process.
IPC: C08B1/00
Filed: 1979-10-11
Abstract: Carboxymethylcellulose (CMC) and its derivatives are cross-linked by reaction with a carbodiimide. By this reaction, hydrophilic substances are obtained, whose density, in a water solution, is very high and which, under certain conditions, give hydrated gels. These gels are self-destructible and eliminated without causing pollution. The CMC thus cross-linked can be stabilised by addition of phenol amines or organic acids as well as by amino acids.

Title: Hydraulic actuator for a subsea gate valve having a manual override.
IPC: F16K37/00
Filed: 1979-11-02
Abstract: A double acting manual override mechanism for the hydraulic actuator of a subsea gate valve, and a visual indicator device for indicating the gate position. The gate is normally held open by hydraulic pressure and is moved by a spring to a fail closed position in the event of a malfunction. The override includes a drive nut threaded onto the valve stem and a drive sleeve which is telescoped on the drive nut and connected therewith by a series of splines. Spaced apart abutment surfaces are provided on the sleeve to limit axial movement of the drive nut on the valve stem in both directions. Rotation of the sleeve by means of an adapter is translated into rotation of the drive nut which contacts one of the abutment surfaces and thereafter effects axial movement of the valve stem to open or close the gate. The indicator device includes a watertight, transparent housing within which an indicator disc moves in response to movement of the gate.

Patent ES-8207340-A1 (ES)
Title: Water cooling tower having combination splash and film fill structure.
IPC: F28F25/08
Filed: 1981-11-30
Abstract: An improved, high efficiency, combination fill assembly for crossflow cooling towers is provided which employs a strategically located, multiple sheet film fill section in conjunction with splash-type fill to maximize tower performance with a minimum tower height, pumping head requirements, and pressure drop across the assembly. In preferred forms, the fill includes a film fill section presenting substantially separate air and water entrance and exit faces, along with structure above the upper water entrance face thereof for dispersing water and inhibiting exiting of cooling air out of the water entrance face in this fashion "short circuiting" of cooling air is inhibited, and the inertia of airflow is thereby maintained in the desirable crossflowing direction for enhanced water cooling. Separate film packs cooperatively define the overall film fill section, and the packs are advantageously arranged in an inwardly staggered relationship, with the uppermost pack being outermost, i.e., closest to the air entrance face of the fill assembly. Splash fill is employed in the regions of the overall assembly free of film fill packs.

Patent ES-8400394-A1 (ES)
Title: Process for the preparation of 7-chloro-6-methylene-5- oxytetracycline
IPC: A61K31/65
Filed: 1982-10-11
Abstract: The methods currently known for the preparation of meclocycline are unsatisfactory as secondary products which are difficult and costly to remove form during different stages of the synthesis. One of the critical points for the synthesis is dehalogenation of the molecule at the 11 position. We have discovered that by performing this stage in a suitable manner, different from those described previously, an appreciably purer compound is obtained which can be more readily increased to a level of purity for pharmaceutical use. Meclocycline, i.e. 7-chloro-6-methylene-5-oxytetracycline (I) <IMAGE> is the drug of choice for the treatment of skin infections because its antibacterial activity against both gram-positive and gram-negative strains is truly very high, its toxicity is low, its absorption through the skin is virtually zero, and one reason for this lack of absorption both via the skin and via the gastrointestinal tract may be its very great capacity to bind with macromolecules present on the absorption surface. In addition to the absorption spectrum, chemical- therapeutic activity and stability are not affected by exposure to UV rays.

Title: Multiple valve apparatus for performing a fluid-solids contacting process.
IPC: B01J47/10
Filed: 1983-06-06
Abstract: An apparatus is disclosed which is useful in simulating the countercurrent flow of several fluid streams through a bed of solid contact material such as a selective adsorbent. The apparatus comprises a plurality of multi-port valves and is used to direct the flow of different streams into and out of a fixed bed of material at points which are periodically changed. The invention arises in the arrangement of the valves, which minimizes the number of required valves and also minimizes the undesired admixture of different streams in the process lines connecting the contacting bed to the main fluid transfer lines. The valves are arranged in three tiers, with the first tier having sets of valves arranged in series flow and the second tier having sets of valves arranged in parallel . The third tier of valves directs flows between two adjacent fluid feed or withdrawal conduits entering the contacting bed.
