Title: Sew-knitted warp fabrics - have pile incorporated into preformed base layer
IPC: D04B23/02
Filed: 1982-05-06
Abstract: Warp-knitted pile fabrics are sew-knitted with a pile in the form of a non-woven material such as card sliver, bound by hooked needles to a pre-formed base layer. The base layer comprises columns of stitches formed from loops of fibres drawn from the same non-woven material by the hooked needles. The stitches are formed on the underside of the layer, and the fibre tufts are arranged to stand proud on the front side. The pile is incorporated into the base layer in the form of open pile with the fibres standing proud. This avoids the pilling of fibres, and eliminates a subsequent brushing process to remove the fibre pills. The pile fabric is prepd. for use in clothing, soft toys and ground coverings.
Patent ES-8307126-A1 (ES)
Title: Alternating potential electrostatic separator of particles with different physical properties.
IPC: B03C7/04
Filed: 1982-05-17
Abstract: The separator charges the particles to be separated and passes them through an alternating electric field which has a non-uniform intensity in a direction perpendicular to the forward direction, and which also has field lines curved in the same direction. The particles which move along the curved field lines due to their charge are thus subjected to a centrifugal force which effects their separation. The separator includes a pair of conductive electrodes, the first being substantially horizontal or possibly at an angle from the horizontal and the second mounted facing the first at a predetermined angle to it. The electrodes may be planar or curved. The field is supplied by an ac source operating in the range of 3 to 1000 hz. A mechanical vibrator attached to the first electrode imparts the forward motion to the particles.

Patent ES-8403323-A1 (ES)
Title: Tamper-proof cannula support assembly.
IPC: A61M5/14
Filed: 1982-12-02
Abstract: An assembly for supporting a cannula comprises a hub which supports the cannula and which includes a post portion which concentrically surrounds a section of the cannula adjacent to the hub. The assembly also includes a cover which is attachable to the post portion of the hub to enclose the cannula. The cover and post portion are coupled together by a "tamper-proof" connection which normally resists removal of the cover, and thereby attests to the sterile integrity of the needle. The connection can be broken in response to the deliberate application of a predetermined rotational force by the user upon the cover and cannot thereafter be recreated, thereby serving as an outward indication that the sterile integrity of the cannula has been compromised. Both the post portion and the cover remain physically intact, despite the breakage of the connection, to permit return of the cover when desired.

Patent ES-8405548-A1 (ES)
Title: Burnable neutron absorbers.
IPC: C04B35/10
Filed: 1983-02-25
Abstract: A neutron-absorber body for use in burnable poison rods in a nuclear reactor. The body is composed of a matrix of Al2O3 containing B4C, the neutron absorber. Areas of high density polycrystalline Al2O3 particles are predominantly encircled by pores in some of which there are B4C particles. This body is produced by initially spray drying a slurry of Al2O3 powder to which a binder has been added. The powder of agglomerated spheres of the Al2O3 with the binder are dry mixed with B4C powder. The mixed powder is formed into a green body by isostatic pressure and the green body is sintered. The sintered body is processed to form the neutron-absorber body. In this case the B4C particles are separate from the spheres resulting from the spray drying instead of being embedded in the sphere.
