Title: Detection of antigens and nucleic acids
Inventor: DREW TREVOR
IPC: C12Q1/68
Filed: 1993-10-01
Abstract: A novel application for leucocyte retention filters is provided in the form of a method and kit for isolating and/or identifying foreign antigens and/or nucleic acids associated with leucocytes in fluids derived from a human or animal body, and treating, preferably with detergent, in a manner such as to expose them for isolation and/or detection. The method and apparatus provides a simple to obtain yet rapid determination of foreign antigens and/or nucleic acids associated with the leucocytes and thus the likely presence of organisms of which these antigens are characteristic.  One significant advantage of this method is that it offers the preparation of a sample outside the laboratory using a few reagents, a syringe and a filter. Using this method the inventors have assembled a pen-side test that can detect animals persistently infected with BVD virus that takes only 1.5 hours, compared to the 7 days required for a virus isolation test.

IPC: A61L31/06
Filed: 1992-12-21
Abstract: The invention relates to a copolymer of at least one lactone and at least one cyclic carbonate, the carbonate being polycyclic.  This makes it possible to obtain cross-linked copolymers. The mechanical properties of objects obtained with these are considerably better than the mechanical properties of objects on the basis of non-cross-linked copolymers. The material is tough - in particular the tensile strength is higher -, impact resistant, less crystalline than non-cross-linked copolymer and it is biodegradable.

Title: Apparatus for Near Vertical Laying of Pipeline
Inventor: WILKINS JESSE R
IPC: F16L1/19
Filed: 1994-08-10
Abstract: An apparatus for near vertical laying of pipeline offshore.    A support base and framework on a lay vessel support an alignment tower that extends upwardly from the base and is designed to support the pipe joint to be added to the pipeline.  A support tower that supports the weight of the pipeline is attached to the support base such that the support tower extends downwardly therefrom into the water.  A travel block is adapted for movement along the length of the tower for raising or lowering the pipe and pipeline.  A pedestal that is movable between open and closed positions for receiving a pipe section from the travel block and supporting the weight of the pipeline is positioned near the bottom of the tower.  A strongback or boom may be used to grasp a pipe joint from a ready rack and transfer the pipe joint into the alignment tower for addition of the pipe joint to the pipeline.   The extension of the support tower into the water eliminates the need for a stinger.  The attachment position and extension of the support tower into the water also lowers the center of gravity of the apparatus.

Title: Ceramic composites having a weak bond interphase material selected from monazites and xenotimes
Inventor: MORGAN PETER E D
IPC: B32B18/00
Filed: 1994-12-07
Abstract: Thermodynamically stable ceramic composites are provided for use in high temperature oxidizing environments. A phosphate selected from monazites and xenotimes functions as a weak bond interphase material between the constituents of the composites.  Monazite comprises a family of minerals having the form MPO4, where M is selected from the larger trivalent rare earth elements of the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, and Tb) and coupled substituted divalents and tetravalents such as Ca or Sr with Zr or Th.  Xenotimes are phosphates similar to monazite where M is selected from Sc, Y, and the smaller trivalent rare earth elements of the lanthanide series (Dy, Ho, Er, Tm, Yb, and Lu). High temperature ceramic composites that include monazite or xenotime and exhibit damage tolerant behavior or non-catastrophic fracture may be fabricated in a variety of material systems and reinforcement morphologies, including multilayered laminar composites; fiber, whisker, and particulate reinforced composites; and hybrid laminar composites. Alumina fibers may be used in single crystal or polycrystalline form as a reinforcement material. In preferred embodiments, the ceramic matrix comprises a material similar to the reinforcement to improve compatibility of the composite materials. The interphase material allows debonding and "frictional"  sliding between the constituents of the composite and inhibits crack growth across the interface.

Title: A ball slide system
Inventor: SCHROEDER GERHARD
IPC: A47B88/49
Filed: 1994-04-26
Abstract: A withdrawal guide for a drawer. In an withdrawal guide for a draw, it is intended to make the production of said guide possible with less material and thereby reduce the weight of said guide. In the withdrawal guide according to the present invention, the guide rail (12) is of identical cross section and shaped so as to be angular.  The unattached edge areas that are remote from each other extend in a curve that is oriented inward, so as to form ball-bearing guides, so that in each instance three ball bearings form a set.  In order to keep the installed height as low as possible, the edges of the withdrawal rail 11 and of the guide rail 12 that are proximate to each other can overlap. The withdrawal guide according to the present invention is particularly suitable for drawers used in furniture.
Patent CA-2141924-A1 (CA)
Title: Method of making pressure sensitive adhesive tape rolls with a transparent to the core appearance
Inventor: SINN MICHAEL J
IPC: B65H18/10
Filed: 1995-02-06
Abstract: The method of the present invention provides a way to make rolls of high shear strength pressure sensitive adhesive tapes with a transparent to the core appearance in a relatively short time and without the need to subject the rolls to additional method steps. Moreover, the present invention achieves such transparent to the core appearance by sufficiently wetting-out the adhesive on the tape backing to remove microscopic air bubbles entrapped within the harder and less deformable high shear strength adhesive layers. The method comprises a rewinding method and is characterized by the use of a pack roll during rewinding to provide a sufficiently high contact pressure to the non-adhesive side of the tape substantially at the application point of the tape to the tape roll. In one aspect, a sufficient contact pressure is provided by the pack roll so that the pressure sensitive adhesive tape rolls are made with a transparent to the core appearance at the time of the rewinding step.  In another aspect, the method further includes the step of aging the tape roll after the rewinding step is complete for allowing the tape roll to become transparent to the core after the rewinding step.

Title: Non-invasive fetal probe
Inventor: MEANTHREL WILLIAM G
IPC: A61B5/288
Filed: 1995-04-03
Abstract: ABSTRACT           A non-invasive fetal probe attaching to the presenting part of a fetus and sensing at least one fetal parameter during labor and delivery.  The body of the probe is formed of a conductive hydrogel which is adhesive to both wet and dry surfaces.  The hydrogel is either formed into a suction cup shape or is coated on the inside surface of a suction cup shell.  It is the combination of both the suction cup shape, which initially holds the probe to the fetus, and the hydrogel material, which allows for increased adhesion in the wet environment of the mother's womb, which enables the probe to be securely attached to the fetus during labor and delivery.  In one specific embodiment, the probe is a non-invasive fetal heart rate probe having a maternal heart rate sensor which detects the maternal heart rate to serve as a reference and a fetal heart rate sensor for monitoring the fetal heart rate.  The maternal and fetal heart rate sensors are separated by an electrical insulation material which can form the suction cup.

Title: Encoder/decoder and method for efficient string handling in data compression
Inventor: KLAYMAN JEFFREY T
IPC: H03M7/30
Filed: 1994-08-19
Abstract: A method (100) and device (200) increase efficiency of a data compression encoder or decoder by testing whether an input string is a maximum length string upon successful match of the input string in a dictionary. Where the length of the input string is equal to a predetermined maximum string length, the string matching process is terminated without processing an additional input character that would cause an unsuccessful string match. The maximum length string test is accomplished by testing a string length counter for the value zero, where the string length counter is set to the maximum string length value when the input string is NULL or alternatively is set to the maximum string length minus one when the input string is a one character string, and the string length counter is decremented for each input character that extends the matched input string.
