Patent ES-8105458-A1 (ES)
Title: Tube joint to be screwed into a conduit or into an apparatus for creating a closed circulation circuit of a pressurized fluid, and method for making same.
IPC: B23B5/36
Filed: 1980-07-03
Abstract: The connecting piece includes a hollow many-sided head and a hollow screw which forms one piece with the many-sided head. The screw is provided with an external thread so that it can be screwed into the internal thread of a part of a line or an apparatus. A chamber-like circular recess is worked from below into the many-sided head in the proximity of the end of the thread of the screw. The circular recess is worked into the many-sided head in one operation. The cutting tool is first guided into a gate at the end of the thread of the screw perpendicularly to the longitudinal axis of the connecting piece. Thereafter the cutting tool is guided into the bottom surface of the many-sided head in parallel with the longitudinal axis of the connecting piece. In this way a guide surface at the end of the thread of the screw is formed which is free of obstacles. The insertion of the sealing ring into the circular recess is simplified because the sealing ring is guided along the guide surface into the recess without a great effort and without being injured. By tightening the connecting piece the deformation of the sealing ring is limited in an optimal way because the metal of the many-sided head lies on the metal of the part to be connected.
Patent ES-8206268-A1 (ES)
Title: Extrusion die head and method of making the same
IPC: B29C48/32
Filed: 1981-02-13
Abstract: A new extrusion die head and method of making the same is provided that permits two strips of elastomeric material to be extruded simultaneously and one above the other from a single core of extrudate. The head is particularly useful for extruding sidewall strips in the manufacture of pneumatic tires. The head design has features common to both conventional strip extruding heads and to heads for extruding tubular shapes, commonly called tuber heads. However, the head is quite different from both the conventional strip extrusion heads and the conventional tuber heads, and has the advantage that it permits two strips to be extruded simultaneously through passages that are relatively short in length and are no wider than the width of a single sidewall strip. The design of the head and the method of making it are such that the extrusion passage surfaces can be easily machined to provide excellent flow characteristics, and the entire head is easily fabricated and cleaned.

Title: Procedure and means for changing an endless press fabric in the press section of a paper machine.
IPC: D21F1/24
Filed: 1981-09-24
Abstract: Procedure in the press section of a paper machine for changing a felt (20). The normal run of said felt (20) passes in a substantial part in spaces (K) under the floor level (T-T) of the paper machine hall. In said press section its lower roll (12) is rotatably carried in support by one or several cantilevered beams (30). In the procedure the frame inserts (38) carrying one end of said cantilevered beam (30) are first removed and then lifting means (33, 33') provided in conjunction with said cantilevered beam (30) is used to lift the guide roll or guide rolls (15, 17) coming to lie within the loop of the felt to be changed and located in the underside space (K), into an upper position (15, 15') to be adjacent to the cantilevered beam (30). After that the loop (50) of the new felt is spread out to the configuration implied by the rolls coming to lie therewithin, in which shape the felt loop (50) is pushed, using special equipment (40, 41, 42, 43, 44, 45, 46, 47), to encircle the rolls (12, 13, 14, 15 and 17) coming to lie inside the loop and around said cantilevered beam (30) through the space vacated by said removed inserts (38). Then the rolls (15', 17') lifted into the upper position are lowered with their lifting means (33, 33') into their operating position in the underside space (K), whereupon said frame inserts (38) are closed.
Patent ES-8301797-A1 (ES)
Title: Foldable and portable vehicle with foldable handlebar.
IPC: B62K21/06
Filed: 1982-02-12
Abstract: A foldable, portable bicycle in which the handlebar assembly, the seat assembly, the pedal crank and the frame are foldable quickly and easily into a compact and regular-shaped package that is easily portable and storable, and are unfoldable with similar speed and ease into a safe, durable and comfortable bicycle that accommodates adults of normal size. The frame is designed with a low profile that is substantially the same in height and thickness as the dimensions of the wheels and their supports, and the handlebar and seat assemblies extend upwardly to normal height, but fold and collapse, along with the pedals, to substantially within the confines outlined by the folded frame. The steering bearing is housed in a front wheel mount in the form of a narrow arcuate band on the front end of the frame, and has a height that is substantially less than its diameter, about one-quarter the diameter as disclosed. The bearing has at least one set of rolling bearing elements that are confined, both laterally and vertically, in races that are defined between the band and bearing rings on the handlebar assembly and the front wheel support, these being connected through the front wheel support by connecting means that draw them together and against the opposite ends of the bearing. In one embodiment, two series of ball bearings are closely spaced, vertically, on opposite V-grooved sides of an internal flange on the band, and held in the grooves by oppositely opening V-grooves in bearing rings above and below the flange. In another, a single set of ball bearings is confined in an inwardly opening V-groove in the band by beveled edges of two bearing rings cooperating to form an outwardly opening internal V-groove for the balls. In each case, the increased lateral separation of the balls compensates for the reduced axial length to enable the vertically compact bearing to sustain the torque and thrust loads encountered in use.

Patent ES-8403814-A1 (ES)
Title: Stuffing method
IPC: A22C11/12
Filed: 1982-11-15
Abstract: A method of stuffing food product into controllably premoisturized shirred casing using a stuffing machine designed for use with more pliable, fully soaked casing. An internal sizing ring is used to prestretch the premoisturized casing to about its recommended stuffed circumference which significantly reduces stuffing pressure while still achieving the desired stuffed size. The magnitude of the holdback force, and thereby the stuffing pressure, is adjusted by setting the distance between the sizing ring which stretches the casing and a sealing ring which prevents back flow of meat emulsion onto the stuffing horn. After an encased product length is stuffed, and before the gathering and stripping operations associated with the clipping cycle, the sealing ring is advanced away from the sizing ring which serves not only to assist in the advance of additional casing for the gathering operation, but also to reduce the holdback force produced by the sizing ring so that additional casing is more easily drawn from the supply to reduce product pressure buildup during gathering, separating and clipping.
Patent ES-8401781-A1 (ES)
Title: Improvements in or relating to the case-hardening of metal components
IPC: C23C8/02
Filed: 1982-12-16
Abstract: A method of case-hardening a steel component, such as a beater 13 for a hammer grinding machine, comprises forming in part of the surface to be hardened a plurality of holes 20 before subjecting the component to the case-hardening process whereby, during the case-hardening process, the interior surfaces of the holes 20 are hardened, to the normal case-hardening depth, in all directions into the body of the component. There is thus formed a carburised "island" around each hole, and the effect is as if the component had been case-hardened to a depth equal to a depth of the holes in addition to the normal case-hardening depth.

Patent ES-8501568-A1 (ES)
Title: Grooved gas gate.
IPC: F16J15/16
Filed: 1983-08-12
Abstract: The improved magnetic gas gate (42a) of the present invention reduces the back diffusion of gases between adjacent, operatively connected deposition chambers through the relatively narrow flow channel formed between the substrate and the passageway wall (43a) of the gas gate (42a) toward which the substrate is urged by forming a plurality of elongated grooves (86) in the passageway wall (43a) toward which the unlayered surface of the substrate is urged. The grooves (86) are substantially coextensive with the length of the passageway (43) so as to operatively interconnect the adjacent chambers. The flow channels thus established are adapted to accommodate a sufficient flow of inert sweep gases to further reduce the back diffusion of process gases through the narrow flow channel over that achieved by the maintenance of a constant pressure differential between the chambers which thereby establishes a substantially unidirectional gas flow between the chambers.

Title: Fluoroelastomer compositions containing fluoroaliphatic sulfonamides as curing agents.
IPC: C08K5/17
Filed: 1985-01-30
Abstract: This invention relates to a method for vulcanizing fluorocarbon elastomers and vulcanizing agents for use therein. In another aspect, the invention relates to vulcanizable fluorocarbon elastomer compositions containing vinylidene fluoride polymers and vulcanizing agent and adjuvants. Although conventionally vulcanized fluorocarbon elastomers have many useful properties, they generally do not have sufficiently high tensile strength combined with sufficiently high elongation for certain applications. Such applications where high tensile strength, high elongation fluorocarban elastomers would be especially useful include blowout preventers for oil wells, accumulator bladders, and diaphragms. Although increasing the cross-link density of cured elastomers will increase the tensile strength thereof, such an approach often adversely affects the elongation of the elastomer. The invention relates to the achievement of high tensile strength accompanied by high elongation in cured fluorocarbon elastomers by using a novel vulcanizing, or curing, agent which does not adversely affect the other desired properties of the cured fluorocarbon elastomer. The curing agent is a fluoroaliphatic sulfonamide. A second curing agent selected from organic polyhydroxy compounds or polyamine compounds, or their derivatives, must also be employed when the fluoroaliphatic sulfonamide is monofunctional. The invention further involves a method for vulcanizing fluorocarbon elastomers. The composition of this invention can be used to prepare shaped articles that exhibit high tensile strength accompanied by high elongation.
