Title: Methods of use of bovine respiratory syncytial virus recombinant dna, proteins vaccines, antibodies, and transformed cells
Inventor: WERTZ GAIL W
IPC: C07K16/00
Filed: 1991-07-23
Abstract: The present invention relates to recombinant DNA molecules which encode bovine respiratory syncytial (BRS) virus proteins, to BRS  virus proteins, and peptides and to recombinant BRS virus vaccines produced therefrom. It is based, in part, on the cloning of substantially full length cDNAs which encode the entire BRS virus G, F, and N proteins. According to particular embodiments of the invention, DNA encoding a BRS virus protein or peptide may be used to diagnose BRS virus infection, or, alternatively, may be inserted into an expression vector, including, but not limited to, vaccinia virus as well as bacterial, yeast, insect, or other vertebrate vectors. These expression vectors may be utilized to produce the BRS virus protein or peptide in quantity; the resulting substantially pure viral peptide or protein may be incorporated into subunit vaccine formulations or may be used to generate monoclonal or polyclonal antibodies which may be utilized in diagnosis of BRS virus infection or passive immunization. In additional embodiments, BRS virus protein sequence provided by the invention may be used to produce synthetic peptides or proteins which may be utilized in subunit vaccines, or polyclonal or monoclonal antibody production. Alternatively, a nonpathogenic expression vector containing the genes, parts of the genes, any combination of the genes, or parts thereof may itself be utilized as a recombinant virus vaccine.

Patent CA-2091691-A1 (CA)
Title: Lactide production from dehydration of aqueous lactic acid feed
Inventor: SINCLAIR RICHARD G
IPC: C08L67/04
Filed: 1991-09-18
Abstract: The present invention is directed to a method for making L-lactide (LD) from aqueous L-lactic acid. Aqueous lactic acid feed for present purposes comprehends an aqueous mixture of one or more of lactic acid, lactic acid dimer, and lactic acid trimer optionally with LD being present. L-lactic acid is the preferred feed configuration for making L-lactide, and is to be understood even though the configuration symbol is not used throughout this application. Aqueous lactic acid feed is treated for removal of water therefrom until a degree of polymerization (DP) not substantially above about 2 is reached. The treatment then is ceased to produce a crude LD product. LD then is separate from the crude LD product. A  preferred treatment involves heating the feed at elevated temperature to remove water. LD can be separated from the crude LD  product by a variety of techniques to produce an LD-depleted product.  This LD-depleted product, optionally augmented with additional aqueous lactic acid and/or water then can be readmitted to the process for making additional lactide. This cyclic or recycle process embodiment of the present invention enables very high lactide conversions to be realized.

Abstract: DEVICE FOR PRODUCING A TENSILE FORCE   BY MEANS OF A PRESSURIZED MEDIUM                             ABSTRACT            A device for producing a tensile force by means of a pressurized medium comprises an expansion chamber (1), a flexible tube (3) having at least one connection (2) for the pressurized medium and a net (4) which completely surrounds the flexible tube (3) or the expansion chamber (1).  The meshes (5) of the net (4) are compressed when the net is extended radially.  To compensate irregularities in the flexible tube or resultant local pressure peaks  which  arise  when  the  flexible  tube  is  extended,  to effectively reduce the friction, and hence the resultant abrasion or wear, between the net and the flexible tube and to ensure simple, economical manufacture, the meshes (5) are made from cords (6) which are elastic but preferably inextensible or only slightly extensible and which extend over the whole length of the flexible tube (3).  Adjacent cords (6) are looped around each alternately other at predetermined distances apart so that each cord (6) follows an approximately zig-zig course and the meshes (5) so formed have an approximately elongate rhombic shape.

Title: Duplex power control
Inventor: DENT PAUL W
IPC: H04B7/005
Filed: 1993-04-08
Abstract: Measurements of mobile signal strength received at the base station are used to determine the portion of power that should be transmitted by the base station to a particular mobile. Each of a plurality of mobiles measure the relative strength of the base station signal specifically intended for that mobile. The relative strength is compared to either the total base station signal power or to a cumulative ranking of the power of signals intended for other mobiles. That comparison is used to determine whether the mobile should increase or decrease its power.
Patent CA-2111785-A1 (CA)
Title: Fractional sample/symbol time modulator
Inventor: KAEWELL JOHN D
IPC: G06F1/03
Filed: 1993-12-17
Abstract: ABSTRACT OF THE DISCLOSURE   A modulator capable of providing a fractional sample or symbol time employs a decimation counter (23) responsive to a clock having a frequency equal to M/Nx (data symbol clock), where M is an interpolation factor and N is a decimation factor, for generating a data symbol clock to select FSK symbols from a sampled data array (21). A multiplier (26) receives the FSK symbols and multiplies the symbols by a weighting factor determined by the decimation counter. When the decimation counter wraps around due to a modulo M operation, a fractional weight is calculated for the current FSK symbol, then a new FSK symbol is selected, and then a fractional weight is calculated for the new FSK symbol. When the decimation counter has not wrapped, the full weighting, N, is output for the current FSK symbol.

Title: Container closure with external ribs
Inventor: LANDIS H RICHARD
IPC: B65D43/02
Filed: 1994-06-21
Abstract: An injection molded closure and a container for dairy products has a closure with external ribs for preventing jamming together of adjacent lids in stacked relation, and facilitating self-alignment of stacked lids.  The closure has a central circular panel and a sidewall extending generally upwardly therefrom.  The sidewall has upper and lower vertical portions with a lateral offset portion extending therebetween, which define a plug-like portion of the closure.  The sidewall terminates at its upper end at an annular rim.  Upon engagement of the closure with a container, the plug-like section is inserted into the container opening.  The ribs are spaced peripherally about the outside of the closure and include an upper closure-engaging surface for contact with the rim of another closure stacked therebelow, and a lower closure-engaging surface for contact with the lateral offset portion of the other closure stacked therebelow.  The ribs prevent an upper closure from wedging or jamming into the plug-like portion of another closure therebelow, since the ribs will continue to engage with the upper rim and lateral offset portions of the lower closure to prevent downward movement of the upper closure into the plug-like portion of the lower closure.  The outer ends of the lower closure-engaging rib surfaces are rounded, and the intersection of the lower portion of the sidewall and the lateral offset portion of the sidewall is rounded.  These rounded surfaces bear and cam against one another to provide self-centering of non-centered closures.
