Patent CA-2052481-C (CA)
Title: Scanning head
Inventor: TAKAYAMA HAJIME
IPC: H04N1/12
Filed: 1991-09-30
Granted: 1997-05-20
Abstract: A   scanning  head  comprises  a  support  member  for supporting the head in pressing contact with a platen.  The support   member   has   lower   strength   portions   spaced longitudinally  of  the  head,  and  higher  strength  portions alternate  with  the  lower  strength  portions.   The  support member is easily bendable at the lower strength portions, and the higher strength portions are urged by springs toward the platen.   Thus,  the  head  can  come  into  intimate  pressing contact with the platen even if the surface flatness of the support member as a whole is not strictly realized.

Title: Plastic bag dispenser
Inventor: SIMHAEE EBRAHIM
IPC: B65D85/671
Filed: 1992-02-05
Granted: 1998-04-21
Abstract: A plastic bag dispenser holds a continuous roll of bags, connected by perforated separation lines.  The dispenser is provided with a tongue, which the bags are dispensed over, that engages the separation line between the bag at the end of the roll and the next bag.   This begins the separation of the separation line, as well as holds the next bag behind the tongue. A finger is provided on the upstream side of the tongue, with a gap between the finger and tongue.  As a bag is separated, a portion of the front edge of the next bag is held in the gap, holding the bag in position for the next user.  The roll of bags rests in angled grooves in the dispenser that cause the roll to abut  and  frictionally  engage  an  interior  surface  of  the dispenser, preventing free-wheeling of the roll.

Abstract: An interface provides a path to transfer data from a proprietary network to an open system. The proprietary network includes at least one module central processing unit (CPU) and a module memory associated therewith operatively connected to the proprietary network. A shared memory and shared memory logic are interposed between the proprietary network and the open system, thereby forming the data path.      The method comprises the steps of accepting requests for data from the open system by a parasitic task function within the module CPU. The data requested of the proprietary network is obtained and placed in a predetermined location of the module memory in a form understandable to the open systems. A pointer value is placed in the shared memory, the pointer value containing the value of the predetermined location of the module memory, the shared memory being mapped in the addressable memory space of the shared memory logic using virtual memory techniques. The data is obtained directly from the module memory utilizing the pointer value corresponding to the data requested, thereby allowing open systems to access the proprietary system while maintaining the integrity of the proprietary network.

Title: A method for generation of antibodies to cell surface molecules
Inventor: DE BOER MARK
IPC: A61K31/573
Filed: 1993-07-08
Granted: 2011-02-01
Abstract: The present invention relates to a method of generating antibodies directed against cell surface antigens and it uses recom-binant insect cells as immunogens. The insect cells have been transfected with coding regions for a molecule containing a cell sur-face antigen and these antigens are expressed on the surface of the insect cells. Host animals are immunized with these transfect-ed insect cells to generate antibodies directed, against the cell surface antigen. Antibody-producing cells from the host animal are used to generate monoclonal antibody-producing hybridoma cells. Sera and hybridoma supernatants can be tested for the pres-ence of antibodies against the surface antigen, using the transfected cells in a screening assay. Specific antibodies that have been generated by the present method are anti-B7 and anti-CD40 antibodies and they can be used to prevent or treat an antibody-me-diated or immune system disease in a patient. The anti-B7 antibodies can be used to cause T cell, anergy, treat allograft transplant rejection, treat graft versus host disease, and prevent or treat rheumatoid arthritis. An immunosuppressive agent may be co-ad-ministered with the antibody. The anti-CD40 antibodies which bind to the CD40 antigen can be used to prevent the growth or dif-ferentiation of the B cell. Monoclonal antibodies useful in these methods, and epitopes immunoreactive with such monoclonal antibodies are also presented.
