Abstract: Abstract of the disclosure The invention relates to a multiply wood product. The supply of wood suited e.g. for the production of ply-wood has considerably decreased. Consequently, attempts have been made to compensate the deterioration in the quality of the surface finish and in other wood qualities e.g. by means of various coating methods, with varying success. The most important problem has been the insuffi-cient adhesion between the coating and the wood. For the elimination of these problems, a multiply wood product has been developed in which at least one layer is formed by a crude fibre ply blank comprising haphazardly oriented fibre material as well as bonding agents, additives and filler materials. A single hot-pressing step in connection with the production of the multiply wood product forms this blank into homogeneous ply (14) which, by virtue of the partial splitting of the fibre structure and the re-sulting reorientation, which take place during the hot-pressing, fills the irregularities in the surface of an adjacent wood layer (1) and forms a tight synthetic ply of accurate dimensions.

Title: Evanescent wave background fluorescence/absorbance detection
Inventor: LEVIN HERMAN
IPC: G01N21/64
Filed: 1987-02-19
Granted: 1992-05-26
Abstract: Abstract of the Disclosure It is proposed to increase the utility of intracellular fluorescence and absorbance measurements for control of fermentation and cell culture by correcting on-line for background fluorescence of the media, also to be able to measure the fluorescence or absorbance of the fluid media in the presence of suspended cells or particles. The measurements could be extended to measure the optical properties of other fluids which contain suspended particles. This invention uses the characteristics of the evanescent wave at the surface of an optic waveguide. The wave pene-trates into the less dense medium only to about the depth of about 1/2 wavelength. The thickness of media swept by the evanescent wave is much less than the size of a cell, thereby essentially separating the fluo-rescence or absorbance of the media from that of the cells. Apparatus is disclosed for carrying out the methods taught herein, including the use of an optical fiber to generate the evanescent wave and the use of a flat plate waveguide to generate it. Apparatus that can read both bulk fluorescence and evanescent wave fluorescence employs a flat plate waveguide to generate the evanescent wave and fiber optics to create an alternating dual-beam approach to generating both sets of data.

Title: Compensation loops in cathode ray tubes for reducing the magnetic field strength in the tube environment
Inventor: JOHANSSON ROLAND T W
IPC: H01J29/00
Filed: 1987-03-26
Granted: 1991-03-12
Abstract: ABSTRACT OF THE DISCLOSURE A cathode ray tube (CRT) has a deflecting coil sur-rounded by a funnel-like casing of maygnetic material.  The deflecting coil generates a magnetic deflecting field for the electron beam and a magnetic leakage field in the CRT environ-ment.  The leakage field is composed of a dipole field and a quadrupole field.  To reduce the magnetic field strength in the CRT environment a magnetic compensation field which is counter-directed to the leakage field is generated.  The com-pensation field is composed of a dipole field which is gener-ated by a first compensation loop and a quadrupole field which is generated by a second compensation loop.  The first compen-sation loop is substantially flat and at right angles to the magnetic deflecting field.  The second compensation loop is flat and at right angles to the longitudinal symmetrical axis of the CRT and has an upper and a lower part which generate two mutually opposing dipole fields.  The centres of gravlty of the compensation loops lie on the symmetrical axis respec-tively at the forward edge of the funnel-like casing and the forward part of the deflecting coil.  The compensation loops are connected in series with the deflecting coil.

Abstract: - i -PATENT APPLICATION OF              John O. Naples and Eric G. Isacoff and Michael J. Byers for Separation Or Purification of Biomaterials With Particulate Polymeric Adsorbents DN85-42A        JET/ja Abstract of the Disclosure A biomaterial contained in an impure liquid medium is separated or purified by contacting the medium with a particulate polymeric adsorbent which preferentially and reversibly binds the biomaterial to form a complex, isolating the complex by passing the medium through a membrane filter permeable to impurities but not to the complex, and then liberating the biomaterial from the isolated complex into another liquid medium, which may be membrane-filtered as before, to accumulate the biomaterial but not the particles in the permeate.

Granted: 1994-05-31
Abstract: ABSTRACT            " Swirl chamber type combustion chamber for Diesel engine "    In a swirl chamber type combustion chamber for a diesel engine having an injection passage provided for to guide the stream of combustion gas gradually spreading right and left during the injection from the swirl chamber to the main combustion chamber, a top surface of a piston head is provided with a concavity formed in such a configuration as gradually spreading right and left as progressing from the inlet end to the outlet end thereof, for example like an unfolded-fan.  And the inlet end of the concavity is located so as to face to the outlet of the injection passage.  The stream of combustion gas injected from the injection passage is to be guided so as to be sufficiently diffused in the main combustion chamber by the concavity.

Abstract: ABSTRACT     Manufacture of Meat-Based Products A process of producing an evenly cooled comminute of meat particles ready for forming comprises forming a primary comminute from fresh meat, cooling the particles of the primary comminute into a coherent strip on a moving refrigerated surface and subjecting the strip to a secondary comminution with a reduction in particle size and a temperature equalization.

Title: Cracking catalysts having aromatic selectivity
Inventor: GILSON JEAN-PIERRE
IPC: B01J29/06
Filed: 1987-06-04
Granted: 1992-02-11
Abstract: Abstract of the Disclosure An FCC catalyst is made with a zeolite Beta which contains from about 0.1 to 15 wt% based on the weight of the zeolite Beta of gallium, zinc or mixtures thereof.  The catalyst substantially increases the aromatic content of the gasoline compared to just using a catalyst of zeolite Beta.  The catalyst can also be made with an inorganic oxide binder for the metal modified zeolite Beta and other catalytically active zeolite components.

Abstract: Procédé de désacidification d'un gaz, notamment gaz naturel, renfermant H2S et/ou CO2 ainsi que des mercaptans, dans lequel on met en contact le gaz dans une zone primaire d'absorption avec un liquide absorbant régénérable, on évacue en tête de la zone un gaz épuré et en fond un liquide primaire chargé d'H2S et CO2, on soumet ledit liquide à une régénération dans une zone et recycle le liquide régénéré vers la zone. On prélève une fraction du liquide primaire régénéré et la met en contact dans une zone secondaire d'absorption avec le gaz issu de la zone, on évacue le gaz épuré en tête de la zone tandis qu'en fond de cette zone on soutire un courant secondaire de liquide chargé de mercaptans que l'on détent pour produire un liquide secondaire régénéré qui est réunit au liquide primaire régénéré avant de prélever la fraction.

Abstract: - 14 -           R.3022 ABSTRACT      Gamma-decalactone is obtained from a source of ricinoleic acid, for example castor oil, by incubation with Sp. odorus or Rh. glutinis.  The product lactone is obtained by lactonising the product hydroxydecanoic acid. The lactone is of value in perfumery and flavours.
