Title: Extractos de biorresiduos del azafrán como principios activos de productos cosméticos antioxidantes.
Inventor: ACERO DE MESA NURIA
IPC: A61K8/97
Filed: 2016-06-09
Granted: 2018-09-28
Abstract: Extractos de biorresiduos florales del azafrán tras la separación de la especia, para ser utilizados como principios activos de productos cosméticos con propiedades antioxidantes, una vez confirmada la actividad antioxidante esperada de los mismos por su alto contenido en fenoles, flavonoides y antocianósidos, y evaluada favorablemente dicha actividad frente al estrés oxidativo celular mediante experimentación in vitro y sobre cultivo celular de carcinoma hepático. Su importancia radica, en que además de servir de base para la elaboración de una nueva gama de cosméticos con dichas propiedades, se da un aprovechamiento a la gran cantidad de desechos florales generados en la recolección del azafrán, para los que hasta el momento no se ha encontrado ninguna utilidad práctica.

Granted: 1989-08-27
Abstract: The reversing of the direction of rotation of the motor of a fixed vane rotary compressor reverses the direction of rotation of the rolling piston (40).  The rolling piston through viscous friction or frictional torque frictionally engages a reversing disk and causes the reversing disk (50) to move between two positions depending upon the direction of rotation of the rolling piston. The reversing disk has a slot (52) in it which forms the suction inlet and is moved by rotation of the reversing disk.  Thus the slot is in fluid communication with the plenum which is serving as the suction plenum at the time.

Title: The method of recording video signal and apparatus for video signal
Inventor: SASAKI KIYOSHI
IPC: H04N9/797
Filed: 1987-02-17
Granted: 1990-10-10
Abstract: The recording method records each field of a video signal as a set of segments on respective tracks of a magnetic tape. Each segment consists of a sequentially-ordered set of scanning lines which constitute a fraction of the total scanning lines of the field and which extend practically over the entire field, e.g. all the even- numbered or all of the odd-numbered lines of the field. Since each recording track contains scanning lines extending sequentially over one field, a playback signal providing a correctly ordered display image is obtained for playback operation at speeds higher or lower than the standard speed, while utilising the same recording and playback signal processing circuits as are utilised during standard speed operation.

Date Aug. 11, 1988.Gasket used in a fabrication method, wherein a methylmethacrylate prepolymer or a mixture of unsaturated monomers, whose main constituent is methylmethacrylate, or the unsaturated monomer or monomers themselves is (are) introduced into a mold comprised of two parallel plates separated by said gasket, and the mold is brought to a temperature sufficient to complete or carry out the polymerization. The gasket consists of a core of plasticized poly(vinylchloride), said core being sheathed by a thin layer of thermoplastic polymers chosen from among propylene polymers and saturated polymers, said thermoplastic polymer being capable of retaining its elasticity at temperatures ranging from 20 DEG  to 120 DEG  C. and having a melting or softening point higher than 115 DEG C.
