Patent ES-477237-A1 (ES)
Title: Fiber sliver opening roll for an open-end spinning device
IPC: D01H4/32
Filed: 1979-01-19
Abstract: A fiber sliver opening roll of an open-end spinning device is equipped with needles, wherein the needle shaft of each needle is mounted in a bore. The surface of the opening roll is provided with outer, wide recesses which clear or leave free the needles at all sides. Below the bases of the recesses there are located the aforementioned bores which are smaller than the recesses. Between each needle and the side wall of the related recess there is left free a clearance or space. The depth of each recess is greater than the distance at the recess base between the outer surface of the needle and the inner wall of the recess, and which depth amounts to from 1 to 10 times the aforementioned distance. Owing to the provision of each such recess the related needle extends free on all sides between the roll surface and the bore in such a manner that there are prevented fiber jamming and fiber accumulations on the needles.
Patent ES-478671-A1 (ES)
Title: Folding wheelchair.
IPC: A61G5/08
Filed: 1979-03-15
Abstract: A folding wheelchair has side frames connected by front, rear and bottom toggle braces which in the folded position permit the side frames to come together. Each toggle brace is preferably formed from a pair of U-shaped elements hingeably connected at the base of the U, the toggle braces co-operating with the framework such that folding is initiated by lifting upwardly of the bottom toggle brace. This is best achieved by a rigid rod linking the front and rear toggle braces and carrying abutment element for engaging with the bottom toggle brace so that folding of the front and rear toggle braces cannot occur until the bottom toggle brace is lifted. The wheelchair may have at least one toggle brace of U-shaped members with the base of each U divided transversely to provide for relative rotational motion between the portions of each U-shaped member. The wheelchair may also have a novel folding footrest.

Patent ES-8306237-A1 (ES)
Title: Pressure relief valve for hermetically closed containers.
IPC: B65D77/22
Filed: 1981-02-20
Abstract: The valve consists of an elastic hollow valve body (2) which forms a prestorage chamber (8) for gas particles which form in the interior of the hermetically closed container and are to be vented. The hollow elastic valve body (2) swells under the pressure of the gas particles to be vented to form a hemispherical dome. As soon as the venting operation begins, the dome collapses again due to the exit of gas and again closes the container before the internal pressure of the container is balanced with the atmospheric external pressure. The diaphragm (4), ensuring the air-tightness, of the pressure relief valve is not raised by the pressure in the container but is lifted off from the valve seat (3) from the outside by the valve body (2) which swells due to the gas particles.
Patent ES-8405859-A1 (ES)
Title: Production of knitted garments.
IPC: A41D1/00
Filed: 1981-03-24
Abstract: A succession of seamless tubular garment blanks 11 are knitted integrally on a cylindrical knitting machine, each blank 11 including at one end thereof a welt or selvedge 12 forming part of a knitted elasticated portion 13 which is destined to form an elasticated waistband in the finished garment. The elasticated portion 13 is separated from the next succeeding blank 11 by a steam-soluble draw thread 14. After knitting, the blanks are flattened, pre-shrunk and separated in a single steam-treatment operation. An end of each blank remote from portion 13 is then shaped by a cutting machine, and the blank centre-crease folded in a conventional manner. Because the welt or selvedge 12 of each blank is knitted in finished form, there is no need for a separate hemming operation and the make-up of the garment is therefore improved.

Patent ES-8605662-A1 (ES)
Title: Cutting head for yarn cutting device.
IPC: A01D34/416
Filed: 1985-04-09
Abstract: In a cutting head for a yarn cutting device driven by an electric motor, the automatic adjustment of the yarn length effected segment-wise by means of a rotary motion between a yarn bobbin (36) and a sleeve (24) which is axially displaceable and wherein the bobbin is housed. The sleeve (44) is provided on the outside with locking tappets while the yarn bobbin is provided inside with tappets co-operating with the locking tappets. The sleeve (24) may be inserted by sliding with the hand in response to a spring force in order to press the locking by segments. A centrifugal displacement is provided for an automatic adjustment of the yarn. To this effect, at least two spherical radial slots (40) are provided between the casing part (14) and a radial extension (48) of the sleeve (24) in the spherical slots balls (44) are conducted and are pushed to the outside by the centrifugal force. The modification of the spherical slot height on an inclined plane (42) causes, upon a radial outward motion of the balls (44), the spacing apart of the two parts (48, 14), thereby causing a segment-wise unlocking. The various rotation angle segments are limited by lower, respectively upper tappets, with which co-operates a counter tappet controlled by the displacement motion and alternatingly co-operating with one tappet or the other, the segment-wise angular displacement being due to the repeated starts and stops of the motor.
