Title: Trigger locking pin mechanism for mig gun
Inventor: COLANGELO JOHN F JR
IPC: H01H9/06
Filed: 1999-06-29
Abstract: A mig welding gun has a handle with a longitudinal centerline and a hole with an axis transverse to the centerline.      A trigger is received in the handle for rotation about an axis perpendicular to and offset from the hole axis. A spring biases the trigger to a released position whereat the gun is off.      Applying a squeeze force to the trigger rotates it to a depressed position whereat the gun is on. A pin is slidable in the trigger to engage the handle hole when the trigger is in the depressed position. Removing the squeeze force while the pin engages the handle hole locks the trigger in the depressed position. Momentarily reapplying the squeeze force to the trigger causes the pin to disengage from the handle hole and enable the trigger to return to the released position. In a modified embodiment, the pin is engageable with a chap inside the hole.
Patent CA-2277141-A1 (CA)
Inventor: LEES ANDREW
IPC: A61P37/04
Filed: 1998-01-07
Abstract: A process for preparing a protein-polysaccharide conjugate includes racting a protein with a polysaccharide to produce a mixture including a proteinpolysaccharide conjugate and free protein. At least one unreacted reagent or low molecular weight component is removed from this mixture, without removing all of the free protein, to provide a purified mixture that contains the protein-polysaccharide conjugate and free protein. This purified mixture can be used as a conjugate vaccine, immunogen, or immunological reagent. Keeping the free protein in the purified mixture with the conjugate saves time and money in the conjugate production process. In another aspect of the invention, the purified mixture of the protein-polysaccharide conjugate and free protein is reacted with a hapten to produce a conjugate mixture including a haptenprotein conjugate and a hapten-protein-polysaccharide conjugate. Alternatively, the hapten-protein conjugate can be prepared first, this conjugate then reacting with a polysaccharide reagent to produce the conjugate mixture. This conjugate mixture can be treated further to remove the free hapten. The conjugate mixture, including the hapten-protein-polysaccharide conjugate and the hapten-protein conjugate, also can be used as a conjugate vaccine, immunogen, or immunological reagent.

Title: Reduced keyboard disambiguating system
Inventor: KING MARTIN T
IPC: H03M11/22
Filed: 1998-01-22
Abstract: A reduced keyboard disambiguating system (50). The keyboard (54) has twelve keys (56, 60, 62, 64), nine of them labeled with numerous letters and other symbols, and those nine plus one more are labeled each with one of the ten digits. Textual entry keystrokes are ambiguous. The user strikes a delimiting "Select" key (60) at the end of each word, delimiting a keystroke sequence that could match any of many words with the same number of letters. The keystroke sequence is processed with a complete vocabulary, and words which match the sequence of keystrokes are presented to the user in order of decreasing frequency of use. In addition, stems of longer words whose initial letters match the sequence of keystrokes are also presented to the user in order of decreasing frequency of use. The first work (78) in the presented list (76) is automatically selected by the input of the first character in the next word. The letters are assigned to the keys in a non-sequential order which reduces chances of ambiguities. The "Select" key (60) is pressed to select the desired word other than the first word, and spacing between words and punctuation is automatically computed. For words which are not in the vocabulary, a simultaneous unambiguous interpretation of each keystroke is performed to specify each letter of a desired word. The system simultaneously interprets all keystroke sequences as both ambiguous and unambiguous keystrokes. The user selects the desired interpretation. The system also presents to the user the number which is represented by the sequence of keystrokes for possible selection by the user.

Title: A method of generating attribute cardinality maps
Inventor: OOMMEN BASANTKUMAR JOHN
IPC: G06F17/30
Filed: 1999-07-30
Abstract: This invention provides a novel means for creating a histogram for use in minimizing response time and resource consumption when optimizing a query in a database, and other like structures, the histogram being created by placing ordered elements into specific range until the next element to be considered for inclusion in the range is a predetermined distance from the (generalized) mean value associated with the elements within the range, whereupon that next element is placed in the following range. Similarly, the following ranges are closed when the next element to be considered for inclusion in the range is greater than a predetermined distance from the (generalized) mean value associated with the elements in that range, whereupon that next element is placed in the following range. For each range, the location and size of the range is recorded with, for example, the mean value, the slope or other attribute characterizing one or more elements in the range. The invention has also applications in pattern recognition, message routing, and in actuarial sciences.

Patent CA-2283630-A1 (CA)
Title: Ligand/lytic peptide compositions and methods of use
Inventor: ENRIGHT FREDERICK M
IPC: C12N15/09
Filed: 1998-03-27
Abstract: Amphipathic lytic peptides are ideally suited to use in a ligand/cytotoxin combination to specifically inhibit cells that are driven by or are dependent upon a specific ligand interaction; for example, to induce sterility or long-term contraception, or to attack tumor cells, or to selectively lyse virally-infected cells, or to attack lymphocytes responsible for autoimmune diseases.  The peptides act directly on cell membranes, and need not be internalized.  Administering a combination of gonadotropin-releasing hormone (GnRH) (or a GnRH agonist) and a membrane-active lytic peptide produces long-term contraception or sterilization in animals in vivo. Administering in vivo a combination of a ligand and a membrane-active lytic peptide kills cells with a receptor for the ligand. The compounds are relatively small, and are not antigenic. Lysis of gonadotropes has been observed to be very rapid (on the order of ten minutes). Lysis of tumor cells is rapid. The two components -the ligand and the lytic peptide- may optionally be administered as a fusion peptide, or they may be administered separately, with the ligand administered slightly before the lytic peptide, to activate cells with receptors for the ligand, and thereby make those cells susceptible to lysis by the lytic peptide. The compounds may be used in gene therapy to treat malignant or non-malignant tumors, and other diseases caused by clones or populations of "normal" host cells bearing specific receptors (such as lymphocytes), because genes encoding a lytic peptide or encoding a lytic peptide/peptide hormone fusion may readily be inserted into hematopoietic stem cells or myeloid precursor cells.
