Title: Process of making a torus-shaped hollow body from mouldable and hardenable material.
IPC: B29C45/14
Filed: 1979-06-11
Abstract: Production of hollow shaped bodies made of pourable and hardenable material, particularly polyurethane tires, in a mold cavity having a deformable membrane.

This minimizes air bubbles in the shaped body. A piston-cylinder unit movable with the inflow and outflow of liquid to the deformable membrane may be used to accurately control feed of polyurethane material to the mold cavity.
Patent ES-484195-A1 (ES)
Title: Friction lining
IPC: F16D69/00
Filed: 1979-09-14
Abstract: A friction lining 3, preferably for clutch discs of motor vehicle clutches, which is connected by rivets 5 with a lining carrier 2 and comprises a wear zone extending from the friction surface to the rivet head, and a remainder zone from the rivet head to the surface of support on the friction lining carrier. The friction lining 3 comprises lightening spaces 8, 10 in its remainder zone y. The two zones may be produced as separate layers joined by adhesive. Thus on the one hand the weight of the friction linings can be reduced, which especially involves a marked reduction of the inertia movement of a corresponding clutch disc, since the friction linings as is known are arranged in the radially outer region, and furthermore these lightening spaces can save friction material, which clearly reduces the purchase costs of a clutch disc.
Patent ES-486840-A1 (ES)
Title: Machine for impelling viscous liquid material e.g. plastics
IPC: B29C48/465
Filed: 1979-11-30
Abstract: The material is impelled within an annular peripheral channel (20) or adjacent channels of a rotor (10) which rotates within the surrounding cylindrical surface (14) of a station (12), to impel the material between a stator inlet (28) and circumferentially spaced outlet (29), against a stationary blocking member (19) which extends into each channel (20) to build up pressure in the liquid which causes it to flow through the outlet (29). Seals to militate against leakage from the channels are provided between rotor and stator surfaces between which there is a narrow clearance (50), the seals comprising oblique channels (26) formed in one of the surfaces, and acting, during rotation between the surfaces, to force the liquid back along the oblique channels (26) into the impelling channel. The leakage pressure, and penetration, along the channels (26) increases between the inlet (28) and the outlet (29). Power loss in driving the rotor is reduced, by a scraper (31) which removes liquid from the bends (27) between the channels (26), at a location of maximum penetration beyond the outlet (29) and of low pressure adjacent the inlet (28).

Title: Nut and method of forming the same.
IPC: B21D53/24
Filed: 1980-11-06
Abstract: A nut (20) having a plurality of thread convolutions (36, 38, 40) is formed with a plurality of punches from a metal blank to eliminate time consuming tapping operations. To make the nut (20), a pair of punches are used to form recesses in opposite sides of the blank and to form projections which extend axially outwardly from the sides of the blank. The recesses are separated by a web which is shaped by another pair of punches to form an inner thread convolution (36). The two axially extending projections each contain a volume metal which is the same as the volume of metal contained in upper and lower thread convolutions (38,40). The upper and lower thread convolutions (38,40) are formed by cold working the metal of the blank to eliminate the axial projections and form radially inwardly extending projections in the central opening in the blank.

Patent ES-8205003-A1 (ES)
Title: Aqueous metal ammine siliconate solutions, and amorphous materials derived therefrom, and methods of their use
IPC: C08L83/00
Filed: 1981-06-26
Abstract: Aqueous metal ammine siliconate solutions are the reaction products of selected metals or metal derivatives, selected mono-organosilicon materials, certain alkaline nitrogen compounds having the formula R-NH2, and water. Amorphous materials are formed when volatiles are removed from the siliconate solutions. The metal components in the resulting amorphous materials are not readily leached out by normal weathering, washing or the like. The solutions are useful in a method for treating substrates, such as wood, textiles, thread, canvas, carpeting, paper and masonry, to confer antimicrobial properties. The organosilicon component can be selected so that such treatments also confer either hydrophobic or hydrophilic properties to the substrates. The components of the solutions can be selected to enhance their ability to form continuous films of amorphous materials when used in such treatments, making the solutions useful to provide antimicrobial coatings which may be either hydrophobic or hydrophilic. Such amorphous coatings are useful for applications such as wood preservation, masonry water repellents, marine varnishes and as treating agents to give a desirable hand to fabrics. Powdered amorphous materials can be used to produce antimicrobial ointments. The solutions are useful as hardeners for water-reducible resins and emulsions, including latex paints. The solutions can also be adapted to include components which may be slowly leachable from the resulting amorphous materials which can thus serve as controlled-release binders to provide prolonged antimicrobial protection not only to the treated surfaces but also to their immediate surroundings.

Title: Cleaning device to clean the air filter of a cooling air-casing comprising a fan-blown radiator.
IPC: F01P11/12
Filed: 1982-11-12
Abstract: In a self-propelled combine, an engine cooling air screen is cleaned continuously by a rotating exhaust sweep moving close to its external surface. The sweep is in the form of a duct with one side open to the screen. Air is drawn into the sweep and exhausted through the cooling fan by way of an air passage having an inlet opening in the center of the screen communicating directly with the exhaust sweep and an outlet immediately ahead of the inlet side of the fan. Power for rotation of the sweep preferably comes from the propeller action of air passing over air deflector or propeller surfaces at its extremities. Alternatively, the sweep may be driven by a more conventional bladed propeller rigidly connected to the sweep but offset rotationally from it.
