Patent CA-2073093-A1 (CA)
Title: Band management system in communication
Inventor: TAKAMA MAKI
IPC: H04Q11/04
Filed: 1992-07-03
Abstract: The invention relates to a technology with which a call process, a band setting process in particular, from a unit of terminal equipment to a network can be effectively performed.  In a communication system, a communication band required by a unit of terminal equipment is secured by transmitting a SETUP message to a network from the terminal equipment, as in the case of a call procedure in B-ISDN, etc.  When a call is made by the communication control unit of the terminal equipment connected to the network, if the securing of a band in the network is impossible the call is cut off.  However, if the band area in the network is insufficient for an initial band value stored in the SETUP message, a revised band value is produced by subtracting a certain value from the initial band value, and a SETUP message with the revised band value is retransmitted to the network.

Title: Production of recombinant polypeptides by bovine species and transgenic methods
Inventor: HEYNEKER HERBERT L
IPC: C12N15/87
Filed: 1990-11-30
Abstract: A transgene for producing recombinant polypeptides in the milk of transgenic bovine species comprises at least one expression regulation sequence, a secretory DNA sequence encoding a secretory signal which is functional in mammary secretory cells of the bovine species and a recombinant DNA sequence encoding the recombinant polypeptides. A method for producing transgenic bovine species comprises introducing the above transgene into an embryonal target cell of a bovine species, transplanting the transgenic embryonic target cell formed thereby into a recipient bovine parent and identifying at least one female offspring which is capable of producing the recombinant polypeptide in its milk. The invention also includes transgenic bovine species capable of producing recombinant polypeptides in transgenic milk as well as the milk from such transgenic bovine species and food formulations containing one or more recombinant polypeptide. A method for producing transgenic non-human mammals having. a desirable phenotype comprises first methylating a transgene followed by introduction into fertilised oocytes. The oocytes are then cultured to form preimplantation embryos. Thereafter, at least one cell is removed from each of the pre-implantation embryos and the DNA digested with a restriction endonuclease capable of cleaving the methylated transgene but incapable of cleaving the unmethylated form of the transgene.

Title: Aspiration unit for conditioning air during rail car unloading of perishable food products
Inventor: NELSON JOHN L
IPC: B61D27/00
Filed: 1992-09-23
Abstract: A rail car unloading aspiration unit includes a rail car nozzle for providing air conduits for feeding conditioned air to the rail car and for withdrawing air therefrom, ambient air being drawn between a weather shield, hood or cover and a fan chamber mounted on a heating chamber which forces ambient air to pass through a filter and be heated within the range of approximately 77°F - 95°F.  The heated air is passed in proximity to ultra violet lamps after which the air is directed into the rail car nozzle and expelled into the interior of the rail car head surface above the product being unloaded.  During the time that power is applied to the aspiration unit, the fan forces air to be drawn into the unit and conditioned, and the ultra violet lamps remain on.  However, the heaters are selectively activated or deactivated as a function of the temperature of the incoming air in order to maintain the temperature of the air within the desired ranged prior to being exposed to the ultra violet lamps.

Patent CA-2079694-A1 (CA)
Inventor: GRYBA CHARLES M
IPC: E21C41/16
Filed: 1992-10-02
Abstract: An   excavation  method   is   provided,   which   is particularly  suitable  as  an  undercut-and-fill  mining method, wherein posts are inserted into the ground and are used to support a concrete floor of the upper level which serves as a roof for the lower excavation level. Excavation beneath such roof is thereby safely carried out. Also, for mining operations, the excavation is very efficient since it removes essentially 100% of the ore in a single pass. The posts are preferably made of concrete and are inserted into holes drilled in the ground. For greater safety a double post system can be used, which involves placing a second post beside the first and tying them all together with the concrete used to make the floor/roof at any given level of excavation.
