Inventor: SPENCER EMERALD M
IPC: C12P21/08
Filed: 1989-12-21
Abstract: This invention relates to polypeptides that are human somatomedin carrier protein subunits and to processes for producing them. The carrier protein subunits bind to human somatomedin-like polypeptides, also known as insulin-like growth factors. The process involves preparation from a human serum fraction, Cohn IV-1, by a molecule of various chromatographic steps.      This invention also relates to DNA molecules encoding human somatomedin carrier protein-like polypeptides, recombinant DNA molecules, hosts, processes for producing carrier protein-like polypeptides, human somatomedin carrier protein-like polypeptides produced using those molecules, hosts and processes. The invention relates to DNA molecules and their expression in appropriate hosts.      The recombinant DNA molecules contain DNA molecules that code for polypeptides which have a biological activity of the human carrier protein or a human carrier protein subunit capable of binding somatomedins. The DNA molecules, recombinant DNA molecules, hosts, and processes of this invention may be used in the production of polypeptides useful in a variety of therapeutic, diagnostic, and other useful applications.

Abstract: A novel process for the preparation of modified, isocyanurate-containing polyisocyanates containing aliphatically and/or cycloaliphatically bonded isocyanate groups involves the chemical modification of some of the isocyanate groups of organic diisocyanates using aliphatically and/or cycloaliphatically bonded isocyanate groups in the presence of a quaternary ammonium or phosphonium fluoride as catalyst and in the presence of carbon dioxide passed into the reaction mixture. If desired after blocking using blocking agents for isocyanate groups, the modified polyisocyanates obtainable in this way can be used as the isocyanate component in polyurethane paints.

Abstract: Method and means is disclosed for treating pulp, in particular fiber suspensions of the pulp and paper industry, and more specifically, for improvement of pulp mill screening plants, to make their operation more effective and to reduce the need for equipment to reduce the investment costs etc. In the known screening process it is usually desirable to increase the pulpconsistency after the screening to a range of 10 to 15% for storing or after-treatment. It is also desirable to handle rejects by either refining or some other method, but usually at consistency which is higher than that of screening. In other words, the pulp flows always have to be thickened after screening. The present invention comprises a method and means for screening pulp in a pressurized, closed space by means of screens in a consistency range of 1 to 5% and by means of centrifugal cleaners in a consistency below 1%. The various pulp screening and/or cleaning stages are effected in a pressurized state in a closed space in the screening plant. Access of air to the treated pulp is prevented by carrying out the thickening stages in a pressurized state, at the initial pressure corresponding to that of the preceding screening and/or cleaning stage.

Abstract: ULTRAVIOLET CURED GELS WITH CONTROLLED MODULUS AND VISCOSITY                          ABSTRACT           Gels which are useful for coating, encapsulating or potting fragile electronic devices can be made to have specified viscosities in the uncured state and specified hardnesses in the cured state by varying the number of endblocking groups which are acryl functional and the number of endblocking groups which are non-functional.  The gel compositions are made from combining a photosensitization system and a blend of 4 to 90 mole percent of an acryl functional polydiorganosiloxane which has acryl functionality on both ends, 9 to 50 mole percent of a polydiorganosiloxane which has an acryl functionality on one end and a non-functional group on the other end and 0 to 65 mole percent of polydiorganosiloxane which has non-functional groups on both ends.  The total number of acryl functional ends on the polydiorganosiloxane is from 20 to 95 percent and the total number of non-functional ends on the polydiorgano-siloxane is from 5 to 80 percent.

Abstract: A flushing means for drilling tools comprises a guide member (10) carrying a drill bit (20) and being rotatably centered by the mouth of a casing tube (11) which is adapted to follow the drilling tool downhole during drilling. The drill bit (20) has a bit portion (22) that projects laterally beyond and is spaced axially in front of the casing tube (11) so as to drill a hole larger than the casing tube (11). There are external flushing grooves (70,71) on the guide member (10) adapted to lead the outflow of flushing medium and debris from the hole during drilling into the casing tube (11). At least one of these grooves (70) extends from front to rear of the guide member (10). One or more further grooves (71) are open towards said rear while ending blindly into the peri-phery of the guide member (10) spaced from its front. By re-traction of the guide member (10) its front enters the casing tube (11). That closes the blind grooves (71) and an intensi-fied flushing is thus possible via the remaining open grooves (70) that extends from front to rear of the guide member (10). The cutting front (40) of the bit portion (22) is flushed rotatively in counter flow to the rotational drilling direc-tion (8) towards the full length groove (70).

Title: Line signal deterioration removing system
IPC: H04L27/233
Filed: 1990-06-06
Abstract: A system for removing line deterioration elements such as intersymbol interference, carrier frequency offset and phase jitter, etc. from the receiving signal.  An automatic equalizing means (10) compensates for signal deterioration by intersymbol interference.          Next, a carrier phase control means (12) compensates for signal deterioration by carrier frequency offset.          Thereafter, a phase jitter interference removing means (18) allows increase of only phase jitter element by utilizing line characteristic to easily extract phase jitter element.  Since the signal including phase jitter is a low frequency signal, a phase jitter removing means (14) further removes phase jitter by shifting the frequency range to a higher frequency range on the frequency axis and then shifting it to the bandwidth for each processing.
