Patent CA-2155990-A1 (CA)
Title: Hot melt adhesive compositions
Inventor: SUGIE MASAHARU
IPC: C09J153/00
Filed: 1995-08-14
Abstract: The present invention is a hot melt adhesive composition containing a synthetic rubber which is a block copolymer having a specific styrene content, a tackifying resin and a plasticizing oil.  Accordingly, objects are not stained by oil-bleeding.  Moreover, troubles such as moving or adhesive transfer are not caused because deterioration of cohesive strength caused by softening around a body temperature in usage can be prevented.  Accordingly, the hot melt adhesive composition is most suitable for adhesive employed to prevent moving of disposable products such as sanitary napkins or disposable diapers with each cover thereof.

Title: Broad spectrum tumor suppressor genes, gene products and methods for tumor suppression gene therapy
Inventor: XU HONG-JI
IPC: A61K38/00
Filed: 1994-03-24
Abstract: The present invention relates to a broad-spectrum tumor suppressor gene and the protein expressed by that gene in appropriate hostcells. The protein is a second in-frame AUG codon-initiated retinoblasoma protein of about 94 kD relative molecular mass. The present invention also relates to methods of treating a mammal having a disease or disorder characterized by abnormal cellular proliferation, such as a tumor or cancer and methods of treating abnormally proliferating cells, such as tumor or cancer cells. Treatment is accomplished by inserting a host cell compatible p94RB expression vector or an effective amount of p94RB protein into a cell or cells in need of treatment.

Title: Hybrid genes for use in the production of t h-independent cytotoxic t cells
Inventor: LUPTON STEPHEN D
IPC: C12N15/23
Filed: 1994-04-04
Abstract: Recombinant vectors are provided that render the proliferative response of activated lymphocytes, particularly cytotoxic T lymphocytes, of lessened dependency on T helper cells. The vectors are comprised of a region encoding a stimulatory factor polypeptide operably linked to a heterologous transcriptional control region. Expression of the stimulatory factor polypeptide from the recombinant polynucleotide in an activated lymphocyte renders the proliferative response of less dependent on lymphocyte T helper cells. When the lymphocite is activated by binding of its cognate antigen the transcriptional control region causes transcription of the stimulatory factor encoding region. The cells containing the vector, particularly CTLs, are of use in immunotherapy.

Abstract: A foamer nozzle assembly has a foaming barrel defining a turbulence chamber for creating foam upon actuation of the trigger of a trigger sprayer as the conical spray impacts against the smooth inner surface of the barrel as so to emerge as loosely compacted, large foam bubbles having a relatively wide foam spread. A foaming grid in the form of an offset rectangular mesh screen is mounted on a hinged panel for movement between operative and inoperative positions. In the former the grid lies coaxial with the discharge orifice and provides a supplemental foam generator for breaking up the foam bubbles into finer and more concentrated foam having a relatively smaller foam spread. The grid comprises first and second sets of ribs lying in first and second parallel planes, the ribs of the first set being contiguous to the ribs of the second set, and they ribs being mutually spaced apart to define uniformly sized openings therebetween. The ribs of both sets have flat surfaces facing upstream and lie perpendicular to the central axis of the barrel.

Title: Alternator start-up excitation circuit
Inventor: FREDENSBORG HANS CHRISTIAN
IPC: H02P1/16
Filed: 1996-11-29
Abstract: In a type of self exciting brush type alternator which may be used on trucks, school buses, some automobiles, heavy equipment and others, which for initial start-up excitation, depend entirely on residual magnetism being present in the rotor steel. This residual magnetism is often found to be weak and therefore unreliable. This invention completely eliminates this dependance by providing a momentary connection, during cranking motor operation, directly from the battery + terminal of the alternator to the excitation coil (rotor coil) establishing an adequate magnetic flux in the rotor steel which enables the alternator to commence charging as soon as an adequate rotor speed has been reached, i.e. engine idle R.P.M.. This connection to the battery + termanal is achieved by electronicly sensing the battery voltage drop caused by the starting motor when activated, in turn, this connection is interrupted when battery voltage again reaches a value of more than 11.4 volts.
