Patent ES-340826-A1 (ES)
Title: Polyurethanes
IPC: C09K23/00
Filed: 1967-05-22
Abstract: Polyurethanes having discrete particles of a solid therein are prepared by sprinkling solid particles into a liquid organic compound containing hydrogen atoms reactive with an organic polyisocyanate while the liquid is being stirred to form a slurry, subjecting the slurry to a shearing action to break agglomerates of solid therein into discrete particles, flowing the slurry in a thin film to allow entrapped air bubbles to escape, diluting the resulting slurry with additional liquid organic compound and thereafter mixing the resulting dispersion with an organic polyisocyanate. The product may be in cellular form in which case a blowing agent is incorporated into the additional liquid organic compound. The particles may be of zirconium silicate, gypsum, limestone, chalk, talc, silica, zirconium oxide, silicon oxide mixtures, calcium carbonate, carbon and opal fines, clay and especially barium sulphate and are preferably preset in amounts of from 15 to 4 parts per part of the reactive hydrogen containing compound in the initial slurry. The reactive hydrogen containing compounds are preferably those having a M.W. of at least 200, those specifically exemplified being a condensation product of glycerine and propylene oxide and of hexanetriol-1,2,6 and propylene oxide. Conventional blowing agents, emulsifiers, silicone oil stabilizers, and catalysts such as tertiary amines and/or organometallic compounds may be used in the production of the polyurethanes.

Patent ES-381192-A1 (ES)
Title: Loop-cutting apparatus
IPC: A44B18/00
Filed: 1970-06-26
Abstract: Apparatus for cutting pile loops 2 of a fabric 1 into two parts 3, 4 of unequal length comprises comb-like teeth 12 onto which the loops 2 are capable of being pushed by relative movement between the fabric and the teeth, the free ends of the teeth 12 being bent so that each forms a hook 14 the curved part 16 of which has a cutting edge 17, and a knife 21 having a cutting edge 22 which extends transversely of the teeth 12 for cooperation with the row of cutting edges 17. In one embodiment, Fig. 1, the teeth 12 are constituted by flat steel springs either integral with, press-fitted to or soldered to a back 8 to form a comb 9. The fabric 1 passes through a slot 18 in a base 5, over a guide member 6 adjustable relative to the base 5, and is removed through a slot 19 after loop cutting. The fabric may be fed either intermittently or continuously so that the springs 12 pass between the rows of loops 2 and the relevant hook 14 engages in each loop. The knife 21 reciprocates parallel to the length of the springs 12 to cut the arms of the loops 2 which are in the hooks 14, Figs. 3 and 4 (both not shown), to form hooks 3 and residual portions 4. Adjusting means (not shown) is provided for adjusting the position of at least the rear reversal point of the stroke of the knife. In a second embodiment, Fig. 5, a knife 25 rotates about an axis 20 and has a cutting edge 26 to cut the arms of the loops 2 in the hooks 14. A deflecting rod 27, adjustable in position, holds back the loops 2 before they are engaged by the hooks 14 to prevent them being cut by the edge 26.

Title: Geophysical prospecting methods
IPC: G01V1/00
Filed: 1972-08-18
Abstract: A method for deriving seismic information from over a relatively large expanse of land to determine relevant strike, dip, velocity and related information. The method consists of the utilization of a plurality of strike, dip, velocity (SDV) cross patterned source-receiver arrays disposed at spaced known locations over a selected terrain, thereafter to derive localized and offset seismic data relative to selected pairs of groups of the SDV cross patterns with further signal processing to smooth and integrate strike, dip and velocity information over a specific substratum. The method utilizes information as derived from each SDV cross pattern, as well as offset seismic signal information derived from source/receiver combinations spanning two selected SDV cross patterns.
Patent ES-407632-A1 (ES)
Title: Industrial technique
IPC: F28F9/22
Filed: 1972-10-14
Abstract: An illustrative embodiment of the invention alleviates the stresses that are caused by the application of relatively cold feedwater to a heat exchanger tube sheet. The colder feedwater that characterizes a low load condition in a nuclear power plant is admitted to the heat exchanger riser chamber that is adjacent to the primary coolant outlet head tube sheet by way of an inlet bypass system. The bypass prevents the thermal shock that otherwise would have resulted from the exposure of the tube sheet on the one side to cold inlet feedwater and, on the other side, to a very hot primary coolant. As the feedwater temperature increases with the power plant load and approaches the primary coolant outlet temperature, the bypass system is turned off. The main feedwater inlet nozzle then discharges into the heat exchanger in an essentially direct fluid communication with the tube sheet.

Title: Extraction of n-blocked amino acid from aqueous solutions
IPC: C07C67/00
Filed: 1974-07-31
Abstract: N-blocked amino acids and N-blocked peptides are obtained in the form of their esters from their aqueous solutions or slurries with the aid of a novel extraction process, wherein the N-blocked amino acid or the N-blocked peptide is converted to a water-insoluble ester by treating the solution with a diazo compound containing the ester group to be introduced, in the presence of a water-immiscible solvent, resulting in a solution of the ester in the organic solvent. Diazo compounds particularly suitable for this process correspond to the formula (I) < IMAGE > wherein R<1> denotes a hydrogen atom or an organic group and R<2> denotes an organic group, or R<1> and R<2> together with the carbon atom to which they are bonded form a cyclic organic group. The process is applied with particular advantage to the isolation of penicillins and cephalosporins from fermentation broths.
