Patent CA-2195309-A1 (CA)
Title: Methods for the preparation of retroviral particles and cell lines deficient in the alpha-galactosyl epitope
Inventor: ROTHER RUSSELL P
IPC: A61K35/76
Filed: 1995-07-14
Abstract: Methods and compositions are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The reduction of levels of galactose alpha (1, 3) galactosyl epitopes on the retroviral vector particles and/or the blockade of antibody binding to such epitopes have been found to render the particles less sensitive to inactivation by complement mediated mechanisms, and to thus allow transduction in the presence of complement containing body fluids. Means are provided for obtaining such reductions.

Title: Adhesive tape compositions and method for covering roofs
Inventor: DAVIS JAMES A
IPC: C09J123/16
Filed: 1997-03-27
Abstract: An adhesive tape composition includes a polymer blend comprising at least one ethylene-propylene-diene terpolymer and at least one fully saturated adhesive-enhancing polymer miscible with said at least one ethylene-propylene-diene terpolymer. The tape adhesive composition further includes at least one tackifying additive compatible with said polymer blend and a sulfur and organic accelerator cure package for said polymer blend, the adhesive composition being devoid of butyl rubber which is found in most other adhesive tape compositions. This composition is seen as providing excellent long-term heat aging, weathering resistance, and low temperature properties as compared to adhesive tape compositions containing butyl rubber. Moreover, the adhesive tape composition provides more surface tack, better "quick-grab", and higher green strength as compared to adhesive tape compositions containing 100 percent EPDM rubber.     A method is also provided for covering roofs which includes the step of employing the adhesive tape composition.
Patent CA-2201677-A1 (CA)
Inventor: BUCHANAN ERIC SCOTT
IPC: B60R21/26
Filed: 1997-04-03
Abstract: An adaptive airbag inflation method. The inflator includes a main chamber containing a quantity of stored inert gas. The chamber additionally includes two separate heating devices to heat the stored gas. To provide adaptive performance, one, or the other, or both of the heating devices may be fired, depending upon the severity of the collision. The heated stored gas increases in pressure and breaks free of the chamber to inflate the cushion. If both heating devices are fired, there may be a time delay between firing, and this delay may be greater than the time required for the gas to begin exiting the chamber. As such, the second heating device may fire after the partially heated gas has flowed from the chamber.

Title: Portable multi-compartment chemical storage and mixing tank
Inventor: FILSON BRAD S
IPC: A01M7/00
Filed: 1997-10-21
Abstract: A portable holding and mixing tank is provided with a valving assembly, the activation of which responsively enables substantial simultaneous flow of each dissimilar liquid contained within the respective holding compartments to a manifold assembly. The substantial simultaneous flow of each dissimilar liquid to the manifold assembly thereby minimizes (if not eliminates entirely) the possibility that incorrect mixing ratios of the dissimilar chemicals will occur. The manifold assembly mixes the liquids and discharges the mixed liquid through a meter to a transfer conduit. As such, the mixed liquids may be transferred to a storage tank (for example, a storage tank associated with agricultural spraying equipment).

Abstract: In   a   transmitter,    at   least   some   of synchronization patterns  in  a  signal  having  frame structure are inverted in a bit inverting circuit, and a plurality of  channels of  signals which  include a signal  having  the  inverted  synchronization  patterns are  multiplexed  and  transmitted  in  a  time-division manner.  In a receiver, the time-division multiplexed channels are demultiplexed into indivisual channels.          Then, frame synchronization is performed on the basis of  the  channel  having  the  inverted  synchronization patterns among the demultiplexed channels.   With the frame  synchronized  channel  as  a  reference,   the remaining channels are identified.  There is no need to provide a synchronization circuit in each channel, and the size of the system is not increased.
