Title: Hand-held detection system using gc/ims
Inventor: THEKKADATH GOVINDANUNNY
IPC: G01N30/30
Filed: 1999-02-10
Abstract: A portable gas chromatograph-ion mobility spectrometer (GC-IMS) includes a sample adsorbing ribbon (220) having a sampling position (205) and second desorption position (206). The sample is desorbed by activating heaters (210, 211). The desorbed sample passes to a chromatography column (209b) which is then heated by a third heater (212). The separated sample is passed to a cold ion mobility spectrometer (213) for analysis.

Title: Rust-resistant calcium steel
Inventor: TAKEUCHI SHUJI
IPC: C21C7/064
Filed: 2000-10-04
Abstract: The composition of inclusions and the S concentration in steel are controlled in a manner such that, among the CaO-containing oxide inclusions present in a Ca-containing steel, an equilibrium S soluble amount (%S inc.) of at least 80% of the oxide inclusion particles having a particle diameter of 2 µm or more are about 0.03 wt% or less, thereby inhibiting rust formation due to the inclusions, thus solving a problem which has long been of concern in Ca-containing steels.

Title: Cd147 binding molecules as therapeutics
Inventor: GREEN LARRY L
IPC: A61P29/00
Filed: 1999-03-03
Abstract: In accordance with the present invention, we have discovered that the molecule CD147 as expressed on certain cells, such as T-cells, B-cells, and/or monocytes, can be utilized for the treatment of a variety of diseases. In particular, we have demonstrated that antibodies that bind to CD147 and that result in the killing of such cells, for example, through the binding of complement, is efficacious in the treatment of diseases. Diseases in which such treatment appears efficacious include, without limitation: graft versus host disease (GVHD), organ transplant rejection diseases (including, without limitation, renal transplant, ocular transplant, and others), cancers (including, without limitation, cancers of the blood (i.e., leukemias and lymphomas), pancreatic, and others), autoimmune diseases, inflammatory diseases, and others.

Patent CA-2330031-A1 (CA)
Inventor: ESTES DANIEL L
IPC: H04N7/173
Filed: 1999-03-12
Abstract: In a communications network having a primary communication path, a bi-directional secondary communication path. The primary communication path delivers downstream signals from a headend to a subscriber location. The secondary communication path transmits return signals from the subscriber location to the headend, and also provides an out-of-band transmission path for downstream signaling. The present invention meets the needs in the art by allowing return signals to be transmitted upstream over the secondary communication path, thereby avoiding the consumption of bandwidth in the primary communication path. Moreover, downstream signals which do not need to be transmitted in the downstream band can be transmitted over the secondary communication path, further reducing the consumption of bandwidth in the primary communication path.
Patent CA-2330222-A1 (CA)
Inventor: VAN LUNTEREN JAN
IPC: H04L12/743
Filed: 2001-01-05
Abstract: For a system in which data packets are to be handled according to one of several rules, depending on two (or more) criteria present in each packet, such as source and destination addresses, a classification method is disclosed that allows to determine the applicable rule by a longest-matching-prefix search operation. Range tokens of non-uniform length are assigned to basic ranges of criterion values so that each combination of input values from a packet can be represented by a particular variable length combination of range tokens. A  search tree containing stored rule identifiers is so designed that each particular range token combination, used as input for a longest-matching-prefix lookup operation, will provide the required identifier. Different range token combinations having the same prefix can use the same path to one stored rule identifier, so that this method reduces the storage and time requirements for the classification procedure and allows simple updating when rules change.

IPC: B60T13/26
Filed: 2000-01-31
Abstract: A breaking system is able to meet emergency stopping distance requirements associated with a failed rear axle service control line (40) by modifying the service relay valve (26). The service relay valve incorporates a biased double check valve (100) so that an additional or secondary control line (50) from the foot control valve (20) communicates with the service port of the relay valve. If the primary circuit is operational, a biasing force imposed on the double check valve permits normal operation via the primary service line. On the other hand, if the primary service line is lost, the biasing force is overcome and communication between the secondary service line and the service port (68) of the relay valve is established.
