Patent CA-2171144-A1 (CA)
Title: Human t-cell line infected with hiv-2 which secretes functionally intact hiv-2 gp160
Inventor: SARNGADHARAN MANGALASSERIL GOP
IPC: C12N5/0783
Filed: 1996-03-06
Abstract: A novel cell line chronically infected with HIV-2NIHZ virus secretes  the  precursor  of  the  viral  envelope  proteins  in extracellular medium.  The cells grow well in serum-free medium which enables the concentration of the conditioned medium of the cells to be greatly increased (>100 fold). Such a concentration step is otherwise impossible to achieve if the cells are grown under conventional conditions using 10% fetal calf serum.   A specific affinity procedure is provided to purify the gp160 protein from the concentrated conditioned medium of cultures of 100 liter batches  using a mouse monoclonal  antibody to the HIV-2 gp41 protein, which is a part of the gp160 protein.  This purified HIV-2 gp160 reacts with high specificity and sensitivity with the anti viral antibodies of HIV-2 infected humans by several criteria such as i)  ELISA,  ii)  western blot analysis,  and iii)  radioimmuno-precipitation of metabolically labeled gp160 from the same cell line.  The purified HIV-2 gp160 from this cell line is therefore a diagnostic tool for the detection of HIV-2 infection in humans.  In view of the predicted oligomeric property of gp160 and its close conformational similarity to the virion envelope,  the purified gp160 can also be useful for the development of vaccine strategies against HIV-2 in humans.

Inventor: BERGERON RAYMOND E
IPC: B66C3/02
Filed: 1995-05-17
Abstract: L'invention concerne un godet (10) pour pelles mécaniques constitué de deux moitiés (12 et 14). Chaque moitié de godet (12, 14) comprend une paire de parois latérales (16) espacées entre lesquelles s'étend une paroi d'extrémité (18) formant une pelle pour chaque moitié (12, 14). Les moitiés de godet (12, 14) sont fixées pivotantes l'une à l'autre de sorte que les pelles soient en face l'une de l'autre et puissent être déplacées entre une position ouverte dans laquelle les pelles sont à une certaine distance l'une de l'autre, et une position fermée dans laquelle les pelles sont en regard l'une de l'autre et forment une chambre porteuse de charge. Les parois latérales (16) des moitiés de godet (12, 14) se chevauchent lors de la fermeture, ce qui réduit au minimum la perte de charge par les côtés du godet au cours d'une opération de pelletage. Par ailleurs, une soupape à clapet (32) permet à l'eau et à l'air de s'échapper librement de la chambre intérieure du godet lorsque celui-ci est abaissé, tout en empêchant la perte de charge depuis l'intérieur du godet.

Title: Electrical connector having press-fit contacts for circuit board mounting
Inventor: KINSEY FORREST IRVING JR
IPC: H01R4/02
Filed: 1995-12-06
Abstract: An electrical connector (20) having a housing block (24) with a plurality of passageways (50) into which are inserted respective contact terminals (34). The passageways and the contact terminals are so designed that the contact terminals are press-fit into the passageways and displace dielectric material of the housing block to provide a "seal" which prevents solder flux from wicking up the passageways. In addition, the contact terminals are formed with a longitudinal knurl (38) to prevent rotation of the contact terminals after insertion. Still further, each contact terminal is formed with a frusto-conical retention collar (42) having a rearward facing surface (66) which, upon exiting a passageway, abuts against a recessed stop ledge (64) formed in the housing block to prevent the subsequent removal of the contact terminal from the housing block.

Abstract: Gas, gaseous precursors and perfluorocarbons are presented as novel potentiators for ultrasonic hyper-thermia.          The gas, gaseous precursors and perfluorocarbons which may be administered into the vasculature, interstitially or into any body cavity are designed to accumulate in cancerous and diseased tissues.  When therapeutic ultrasonic energy is applied to the diseased region heating is increased because of the greater effectiveness of sound energy absorption caused by these agents.

Title: High cocoa/chocolate liquor syrups with improved flow properties
Inventor: HOHENTHAL THALIA A
IPC: A23G1/56
Filed: 1997-09-12
Abstract: Compositions comprising cocoa, sweetener, a combination of food-grade enzymes, and optionally chocolate liquor are described.  The compositions provide a cocoa/chocolate liquor flavored syrup having a high concentration of the flavoring, in part due to the substantially higher usage of cocoa and liquor than previous syrups. Additionally, the compositions have excellent flow properties for use in beverages and confections, while further having a low water activity which leads to a longer and more commercially useful shelf life.  Some compositions will also contain an acidulant, a mold inhibitor, and vanilla flavor.

IPC: G06T7/60
Filed: 1997-09-26
Abstract: A method for analysing an integrated circuit (IC). At least a portion of a layer of the IC is scanned using high magnification to obtain images of the IC. The images are registered to create a mosaicked image. An IC layout database is created in the form of a set of polygons from the mosaicked image, where the step of creating the IC layout database is performed after, or pipelined with, the registering step. The process is repeated for plural IC  layers, as necessary. Polygon sets from each layer are vertically registered into alignment with minimal distortion. A netlist or schematic diagram is generated to represent the scanned IC portion based on the registered set(s) of polygons.

Title: Time shift keying digital communications system
Inventor: ERISMAN DAVID E
IPC: H04L27/20
Filed: 1995-04-10
Abstract: A digital modulation technique is disclosed which is unique in that it does not utilize fixed time slots for varying the characteristics of an electromagnetic carrier signal, but actually uses variations of the time slots to transfer the digital information.  The modulation is created by using direct digital synthesis techniques (10) to produce a carrier waveform (21) that closely approximates a sine wave carrier signal that can vary the time it takes for each peak to occur. The peaks of the carrier (21) are tightly controlled to occur at exact discrete time slots that correspond to certain base band digital data. The time slot changes occur precisely at the sine wave peaks to minimize the bandwidth requirement and maximise the data rate.
