Patent NO-178155-C (NO)
Inventor: SHEEHAN MICHAEL T
IPC: C08F12/12
Filed: 1991-06-28
Abstract: Polymers comprising poly(4-hydroxystyrene) and/or substituted poly(4-hydroxystyrene) are produced by polymerizing 4-acetoxystyrene and/or substituted 4-acetoxystyrene monomers, with or without other comonomers, and subsequently performing transesterification. Preferably, the polymers are produced using at least one alcohol as a reaction medium, a chain transfer agent and a transesterification reactant. It is appropriate: to use an initiator which does not comprise a substantially absorbant structure over the 240 to 260 nm range or to use an initiator concentration of less than about 3 mole % of the monomer(s); to obtain a polymerization conversion of the initial polymerization monomers of at least about 90% by weight, or to remove residual monomer(s) from the reaction medium prior to transesterification; to obtain a transesterification conversion of the polymerized monomers of at least 85% by weight; and to avoid the use of transesterification catalysts which can cause the formation of chemical structures which can absorb over the 240 to 260 nm radiation wavelength range. The target polymers have low optical density (absorbance) over a wavelength range from 240 to 260 nm, as well as low optical density over the near UV and visible spectrum (310 to 800 nm); and are useful as photoresist components for use in combination with deep UV, X-ray, and E-Beam imaging systems.

Patent NO-180324-C (NO)
Inventor: GRANT DAVID C H
IPC: B01D53/00
Filed: 1992-05-11
Abstract: A system and method for controlling atmospheric emission of volatile materials such as solvents, used to clean or treat articles incident to their manufacture comprising a treatment chamber and a recirculating closed loop gas and solvent recovery system. The chamber is isolated from the closed loop system, the article to be treated is put into the chamber, the chamber is sealed and gases removed by evacuation, these gases being discharged outside the closed loop system. The articles are treated with solvent, dried with a fluid derived in the solvent recovery system from noncondensable gas, residual in the system. Drying is effected by passing the recovered gases from the closed loop system through the chamber and by evacuation. The gas evacuated from the chamber, containing solvent vapor is retained within the closed loop system. The chamber is vented to outside the closed loop system prior to removing the treated item.

Abstract: The invention is directed to purified and isolated novel ULBP polypeptides, the nucleic acids encoding such polypeptides, processes for production of recombinant forms of such polypeptides, antibodies generated against these polypeptides, fragmented peptides derived from these polypeptides, and the uses of the above. ULBP polypeptide can be found on the surface of human B cell lymphomas. Mammalian forms of ULBP polypeptide in isolated or purified forms are provided. In addition, isolated nucleic acids encoding ULBP polypeptides and expression vectors comprising a cDNA encoding ULBP polypeptides are provided. The ULBP polypeptides can be isolated or synthesized and used to prepare antibodies, and in particular monoclonal antibodies, against the polypeptides. The antibodies, in turn, are useful for detecting the presence of ULBP polypeptides in human cell samples, which can be correlated with the existence of a malignant condition in a patient. ULBP polypeptides stimulate IFN-γ production, NK cell proliferation, and CTL activity.

Abstract: An optical pickup device for a recording and/or reproducing apparatus in which a light beam from semiconductor laser element is converged by an object lens and irradiated on recording tracks of an optical disk and the light reflected by the disk is sensed to read and/or record data signals. The device includes photosensors each having an insensitive central zone and adapted to receive the reflected light to generate tracking error signals. The semiconductor laser element is so arranged that the light beam is projected on the optical disk so that the meridional plane of the light beam extending orthogonal to the junction plane of semiconductor layers of the semiconductor laser element is at such an angle with respect to a tangential line drawn to one of the recording tracks of the optical disk that non-symmetricities on both sides of said tangential line as a function of the de-focusing direction of the beam spot may be compensated.

Title: Method of bleaching cellulose pulp with ozone
Inventor: HENRICSON KAJ
IPC: D21C9/10
Filed: 1990-03-22
Granted: 1996-03-26
Abstract: Ozone bleaching has been extensively studied in laboratory and pilot  scale.   It  has been proved  that  at  low consistencies, i.e. less than 5 %, ozone dissolves well in water and thus good transfer of substance between the ozone and the fibers in the water is achieved.   On the other hand, it has been discovered that the ozone, being a gaseous substance, reacts well also directly with a fiber surface which, however, presupposes that the consistency of the suspension is over 25 %.   Further,  it has been discovered that in the intermediate range between said consistencies ozone cannot satisfactorily contact the fibers.   However, both environmental and pumping factors determine the operation to be carried out at that particular intermediate consistency range of 5 to 25 %.            A characteristic feature of the method of the present invention,  which avoids the disadvantages of prior art methods and permits operation at the consistency range of 5 to 25 %, is that cellulose pulp is pumped with a high-consistency pump to a fluidizing mixer in which O2 /O3 gas is introduced and mixed into the pulp so as to generate foam in which the fibers in the pulp and the ozone used as the bleaching agent are brought to contact with each other, and that the pulp is discharged from the mixer to a reaction vessel.

Title: Process for the suppression of current peaks during commutation of a brushless direct-current motor
Inventor: MEYER HELMUT
IPC: H02P6/15
Filed: 1991-03-22
Granted: 1997-05-06
Abstract: With so-called single-current measurement in the direct-current link of a brushless direct-current motor, there is the problem that current peaks occur in the phase windings during commutation, said current peaks not being detected by single-current measurement in the direct-current link.  Consequently, current regulation during commutation is based on an incorrect actual value of the current.            The object of the present invention is to propose a process that, firstly, measures the motor current in low-cost manner by means of single-current measurement in the direct-current link and, secondly, suppresses the current peaks that occur during commutation.            The object of the invention is achieved in that, in the phase windings, the current buildup is delayed by time period tv in relation to the current decay.

Granted: 1995-04-18
Abstract: A method of processing scrap, single-ply synthetic plastic roof-membrane sheet material having a fabric, with warp and weft strands composed of bundles of synthetic plastic fibers, encased in a polyvinyl chloride plastic envelope.          Comminuted pieces of the scrap are stuffed into a heat-applying, continuous mixer-extruder having screw mechanism within an elongate barrel chamber and the compressed material then is heated to plasticizing temperature and subjected to repetitive shear forces as it moves along the barrel chamber to a die discharge.  The warp strands are separated from the weft strands via said shear force application without substantially reducing the lengths of the strands and strands are then disembodied via said shear forces without substantially reducing the lengths of the fibers to provide separated strand fibers in the mix of material.  Finally, the fibers are randomly dispersed in the mix material and extruded.
