Title: Composite synthetic peptide construct eliciting neutralizing antibodies and cytotoxic t lymphocytes against hiv
Inventor: BERZOFSKY JAY A
IPC: C07K19/00
Filed: 1994-05-13
Abstract: Peptide constructs comprised of multideterminant T helper peptides from the envelope glycoprotein of HIV previously  identified to induce proliferative  responses in four different haplotypes of mice and IL-2 responses in 52-73 % of HIV positive, flu positive patients (cluster peptides), were co-linearly synthesized with the peptide 18 of the V3 loop of HIV-1 gp 160, corresponding to the principal neutralizing determinant of HIV-IIIB and also shown to contain a dominant CTL epitope.  Cognate help for peptide 18 antibody was elicited following a single immunization in all strains of mice which had previously responded to a T cell epitope encompassed  by the peptides. In two strains of mice, the level of neutralizing antibody achieved was comparable to levels adequate for protection from homologous viral challenge in chimpanzees.  After a single boost, much higher antibody titers for 90 % neutralization in the range of 1:1000 to 1:16,000 were achieved. Spleen cells from mice of three distinct MHC haplotypes sharing the Dd class I MHC molecule but with different class II molecules, immunized with the compound peptides, exhibited enhanced gp160-specific CTL activity.

Patent CA-2175194-A1 (CA)
Title: Ice detector
Inventor: PRITCHARD GARY ROBERT
IPC: B64D15/20
Filed: 1994-10-31
Abstract: An ice and snow detector having a tubular duct (10) mounted on a stand (12) which can be fixed to the exterior of, for example, a helicopter. Air is drawn through the duct (10) in the direction of the arrow by means of a venturi arrangement. The detector also comprises an ice probe in the form of an electrically conductive bar (16) mounted diametrically across the duct (10), and three separate, diametrical light channels are formed, just in front of the probe (16) by light emitters (20) and corresponding light sensors (21). In use, and under icy conditions ice builds up gradually on the probe (16), such that the output signals of the light sensors (21) progressively diminish. If the output signal falls below a predetermined level the probe (16) is heated in order to melt the ice. A control arrangement samples the light sensor output signals at predetermined intervals of time and, if any sample differs from the immediately preceding sample by greater than a predetermined step, this is interpreted as a momentary reduction due to, for example, a snow flake and ignored. The detector further comprises means for indicating the severity of the snow and means for testing the reliability of the light channels.
Patent CA-2178382-A1 (CA)
Inventor: FILIMON CRISTIAN C
IPC: H01Q21/28
Filed: 1996-06-06
Abstract: An antenna system and method for use in a portable unit of a wireless telephone headset, wireless telephone headset adapter, or other telecommunication device combines a capacitive coupling antenna with an electric field sensitive antenna. The electric field sensitive antenna, such as a monopole antenna, receives and transmits RF signals when the portable unit is located remote from the user. A patch antenna receives and transmits RF signals when the portable unit is located proximate to, for example is worn by, the user. The patch antenna is a conductive surface for capacitively coupling to a user's body which acts as a radiating and receiving medium. Both the patch antenna and monopole antenna are coupled to an antenna port by matching circuits to tune each antenna for desired RF characteristics. When worn by the user, the RF effects of the monopole antenna are negligible and the patch antenna operates as the primary antenna. When located remotely from the user, the patch antenna will not be capacitively coupled to a body and the RF effects will be negligible as compared with the RF effects of the monopole antenna. The portable unit of a wireless headset receives and transmits signals when the portable unit is located either proximate to the user or remote from the user.

Filed: 1995-02-28
Abstract: A gastrostomy feeding port (100) is dis-closed which includes a housing (20) and a re-silient valve member (10). Housing (20) de-fines an inner passageway (29) which provides fluid communication into a long term indwelling catheter and includes a rigid compression collar portion (21) which defines a valve member re-ceiving cavity (22) within the inner passageway.

Valve member (10) com-pressively fits within receiving cavity (22) by ad-vancing outer wall portion (12) into cavity (22) to thereby cause the outer peripheral edge to be compressed to fit within cavity (22), with com-pression collar (21) pressing inwardly against the peripheral edge of a diagphragm portion (11) to bias slit (16) toward a normally closed position.
