Title: Internet protocol filter
Inventor: COLVIN WILLIAM G
IPC: H04L12/46
Filed: 1997-04-23
Abstract: The IP filter (12), embodying the present invention, is a communications device designed to provide public network (14) or Internet (16) access to nodes (18) of private networks (10), advantageously without requiring the private nodes on such networks to register public Internet addresses. The IP  filter presents a single IP address to the Internet and uses a plurality of IP  ports to solve the problem of IP address conservation. It initiates sessions by assigning private side IP sessions to a unique port of the IP filter's public address. The IP filter effects a translation between a source port number for the private network and a destination port number for the public network for communication therebetween. Benefits of the IP filter include private node security and conservation of Internet-registered addresses.

Patent CA-2276913-A1 (CA)
Title: Electronic ballast with inrush current limiting
Inventor: TWARDZIK RENE
IPC: H05B41/285
Filed: 1999-07-06
Abstract: The electronic ballast has a rectifier arrangement (1) - which is fed by AC power supply voltage (U) - with active step-up converter (SW2), a storage capacitor (C2), a network for limiting an inrush current and two outputs, at which a stabilized DC voltage (U+) referred to housing ground as reference potential (Uref) is output. An inverter (2) is connected to the rectifier arrangement, a load circuit (3) with at least one fluorescent lamp (La1 and/or La2) being assigned to said inverter on the output side. The inverter has a converter network (T1/1, T1/2, C1, SW3, SW4), preferably designed as a push-pull circuit, with two bridge paths, which, in the steady-state operating condition, are alternatively switched through to the reference potential. In this case, the switching network for limiting the inrush current comprises a limiting resistor (Ri), which, in series with the storage capacitor (C2), is connected to reference potential. The junction point between the storage capacitor and the limiting resistor is coupled to the two bridge paths of the converter network in such a way that it is connected, in the steady-state condition of the inverter, via the latter to housing ground and the limiting resistor, which is thus effective only in the switch-on phase, is bridged.

Patent CA-2279492-A1 (CA)
Title: Immunological tolerance to hiv epitopes
Inventor: SCOTT DAVID
IPC: A61K38/00
Filed: 1998-02-13
Abstract: Fusion immunoglobulin (fIg) proteins comprising one or more heterologous epitopes associated with a disease in which immune responsiveness is deleterious are useful to induce tolerance to these epitopes. HIV-1 gp120 epitopes linked in frame with an Ig heavy (H) chain are useful constructs for the induction of epitope-specific tolerance to HIV. Treatment of a subject with such a construct, or with lymphoid or hematopoietic cells expressing or secreting such fIg molecules induces specific immunological tolerance to those epitopes. Such tolerance, by preventing production of antibodies to selected gp120 epitopes, can prevent or inhibit "bystander" apoptosis of uninfected host T cells which have bound the HIV gp120 protein to their surface CD4 molecules and are subsequently cross-linked by undesired anti-gp120 antibodies, thereby priming them for apoptisis in the presence of antigens which activate those T cells. gp120 epitopes corresponding to non-neutralizing B cell epitopes or certain T helper cell epitopes are preferred for producing the fIg molecules. In addition to fIg H chains and complete Ig molecules, DNA encoding such H chain and cells transformed with such DNA are provided.
