Title: Direct detection method for products of cellular metabolism using tof-sims
Inventor: LLOYD KATHRYN G
IPC: G01N23/225
Filed: 2004-09-09
Abstract: A rapid and efficient method for novel biological substance screening by surface analysis has been developed using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS). This method relies on the surface screening of an array of micro-organisms grown on porous membranes, which had previously been in contact with a solid growth medium. ToF-SIMS analysis differentiates among organisms producing different substances, either directly as molecular product, or indirectly through the use of multivariate statistical data reduction techniques. This method has many advantages over traditional microbial screening methods, which require sample preparation and time for assay development.

Title: Modified secretin and method of synthesizing thereof
Inventor: BRIDON DOMINIQUE P
IPC: C07K2/00
Filed: 2000-05-17
Abstract: A secretin or derivative thereof being protected against peptidase activity. The secretin or derivative comprises a peptidic sequence; and a reactive group selected from the group consisting of succinimidyl and maleimido groups capable of reacting with an amino group, hydroxyl group or thiol group on a blood component to form a stable covalent bond. The reactive group is attached at a position along the peptidic sequence that provides, when conjugated to a blood component, a higher stability toward peptidase degradation than the unconjugated secretin or derivative, and maintenance of the therapeutic activity of the unconjugated secretin or derivative. Such a compound is thus effective to provide a source of secretine having a high stability toward peptidases. A method for synthesizing such a compound is also described.

Title: Method and apparatus for mixing fluids for particle agglomeration
Inventor: WILKINS JOHN WALTER
IPC: B01D51/02
Filed: 2004-04-28
Abstract: An aerodynamic agglomerator (10) promotes mixing and agglomeration of pollutant particles in a gas stream, to facilitate the subsequent removal of the particles from the gas stream. The agglomerator (10) is mounted in a duct (11) through which the gas stream flows. The agglomerator (10) comprises a plurality of parallel plates (12) which extend in the overall direction of flow of the gas stream, and are spaced transversely across the width of the duct (11) to divide the duct into multiple parallel passages. The duct (11) is configured and/or has formations therein for creating large scale turbulence in the gas stream upstream of the passages. A vane assembly (13) is provided in each passage for generating a zone of small scale turbulence of such size and/or intensity that the pollutant particles are entrained in the turbulence.  Each vane assembly (13) is located centrally relative to its respective passage and comprises a plurality of sharp-edged vanes (15) spaced successively in the overall direction of flow of the gas stream. The large scale turbulence in the substreams causes each substream to pass through the zone of small scale turbulence in its respective passage so that particles therein are subjected to the small scale turbulence.
Patent CA-2524596-A1 (CA)
Inventor: MENDENHALL DAVID W
IPC: H01R12/71
Filed: 2004-01-16
Abstract: Provided is an electrical connector having first and second surfaces and configured to establish electrical communication between two or more electrical devices. The electrical connector includes an insulative housing and a resilient, conductive contact retained in an aperture disposed from the first surface to the second surface. To contact the electrical devices, the contact includes a center portion from which extends two diverging, cantilevered spring arms that project beyond either surface of the electrical connector. To shorten the path that current must travel through the contact, one spring arm terminates in a bellows leg that extends proximate to the second spring arm. When placed between the electrical devices, the spring arms are deflected together causing the bellows leg to press against the second spring arm. For retaining the contact within the aperture, the contact also includes retention members extending from the center portion that engage the insulative housing.

Title: Fast frequency hopping with a code division multiplexed pilot in an ofdma system
Inventor: TEAGUE EDWARD HARRISON
IPC: H04L5/02
Filed: 2004-05-07
Abstract: Techniques are provided to support fast frequency hopping with a code division multiplexed (CDM) pilot in a multi-carrier communication system (e.g., an OFDMA system). Each transmitter (e.g., each terminal) in the system transmits a wideband pilot on all subbands to allow a receiver (e.g., a base station) to estimate the entire channel response at the same time. The wideband pilot for each transmitter may be generated using direct sequence spread spectrum processing and based on a pseudo-random number (PN) code assigned to that transmitter. This allows the receiver to individually identify and recover multiple wideband pilots transmitted concurrently by multiple transmitters.  For a time division multiplexed (TDM)/CDM pilot transmission scheme, each transmitter transmits the wideband pilot in bursts. For a continuous CDM pilot transmission scheme, each transmitter continuously transmits the wideband pilot, albeit at a low transmit power level. Any frequency hopping rate may be supported without impacting pilot overhead.

Inventor: SHEW JERRY D
IPC: G01F11/02
Filed: 2004-05-14
Abstract: An apparatus converts rotary motion of a motor drive shaft into oscillatory motion of a work piece, for example, in a power tool. The apparatus comprises a planetary gear assembly connected to the motor for rotating an output gear.  The output gear meshes with a drive gear including a drive pin. The drive pin fits in a yoke slot for reciprocation of the yoke upon rotation of the drive gear. The yoke is operatively connected to the work piece. An air flow system cools the power tool housing. The housing has an inlet aperture in the handle portion and an outlet aperture for placing the interior of the housing in communication with the atmosphere. A wall integral with the handle portion engages the body of the motor housing between a first end and openings in the body. The wall provides a barrier to minimize air flow between an intake air portion of the interior of the housing and an exhaust air portion. A fan on the motor drive shaft induces air flow from the intake air portion and exhaust air portion of the interior chamber into the motor housing through openings in the end walls. Air is discharged from the openings in the body.
