Patent ES-374814-A1 (ES)
Title: Process for producing tubes
IPC: B29C33/68
Filed: 1969-12-22
Abstract: Tubes are formed upon a mandrel covered with an elastically compressible layer by applying a solvent resistant inner layer in the form of a foil of polyamide, halogen-substituted hydrocarbon or other plastics material, followed by an additional layer or layers including one of natural or synthetic rubber, and then the unvulcanized tube blank is removed for further processing, damage to the blank being prevented by the elastically compressible layer, which is retained on the mandrel. In a preferred embodiment the elastically compressible layer comprises a braided stocking made from expandible circular fabric, tied down by cords at both ends of the mandrel. The tube blank comprises a seamless polyamide foil tube, produced by injection moulding or extrusion, an intermediate rubber layer, and an outer reinforcing fabric layer. The unvulcanized tube is slid off the covered mandrel and cut into sections which are placed over curved mandrels and then vulcanized to form pipe bends and elbows.

Title: Improvements in and relating to hops
IPC: C12C3/00
Filed: 1970-01-09
Abstract: The alpha acids and beta acids are extracted from resinous hop material such as lupulin in the following process steps: (1) (optional) the hop material is given an initial wash with sodium or potassium hydrogen phosphate buffer solution of pH 4-9to extract selectively tannins and fatty acids, the temperature being kept low enough to avoid substantial dissolution of the alpha acid content of the hop fraction (2) the alpha acids are then extracted with the aid of aqueous disodium or dipotassium hydrogen phosphate, or sodium or potassium citrate, at a pH in the range 7 to 9 and a temperature between 40 and 90 C. and (3) the beta acids are extracted from the residue with a 0À2-2À0% by weight aqueous solution of sodium or potassium carbonate at a temperature in the range 25 to 100 C. Crystallization of the extracted alpha acids and beta acids may be promoted by the addition of acid, e.g. citric acid and gaseous carbon dioxide, respectively. The extractions may be performed by percolating alkali through a column of the lupulin-rich powder or by spraying the alkali on to the inside surface of a packed bed of the powder in a basket centrifuge. In both cases a filter aid (specified) should be included. The extracted alpha acids may be isomerized by boiling at atmospheric pressure for 2 hours at a pH of 9 (or longer at a lower pH). The extracted beta-acids may be oxidized to hulupones by gaseous oxygen at a temperature in the range 70-90 C.

Title: Three - dimensional modular transportable structures
IPC: E04B1/348
Filed: 1971-03-02
Abstract: The structure comprises at least one standardized, rigid, paralellopipedic frame-work, and interchangeable differentiated standardized modular blocks, for constructing a dwelling.

Title: Apparatus for reducing tangential force variation in pneumatic tires
IPC: B24B49/16
Filed: 1976-09-08
Abstract: A method and apparatus for reducing tangential force variation in a pneumatic tire wherein the tire is mounted on a wheel rim, inflated to operating pressure, and rotated under a predetermined load against a loading drum. Force transducers on the axis of the loading drum measure the tangential force variation as the tire rotates. These measurements are placed into the memory of a computer. The computer processes this data to obtain the magnitude of the tangential force variation and the phase angle from an arbitrary location of the variation or the angular displacement to the point of maximum magnitude. The computer outputs a V-shaped ramp voltage level signal for controlling the servo-valve which moves a rotary grinder into grinding engagement with the inner tread ribs of the tire. The grinding is repeated for a number of revolutions depending upon the magnitude of the variation.
