Patent CA-2271099-A1 (CA)
Inventor: OUELLETTE JOSEPH P
IPC: B29C33/04
Filed: 1999-05-05
Abstract: Method of making a mold half part and the mold part apparatus as so made, wherein a molding surface structure is formed having a first molding surface and a second surface remote from the first surface and defining therebetween a generally constant cross-sectional thickness. A heatpipe chamber is operably coupled to the mold surface structure for phase change heat transfer to or from the first surface via the structure and second surface. The heatpipe chamber means encompasses substantially all of the area of the first molding surface projected in a direction perpendicular to the parting line of the half mold part and in a preferred embodiment is in the form of cup-like or box-like shell having side walls joined to a bottom wall and having an open top closed by the molding surface structure so as to define a single chamber at least generally co-extensive and subjacent to the molding structure first surface. This chamber is sealed, evacuated and lined with wick material and charged with a suitable fluid to thereby be operable as a heatpipe. Cooling coils or heating elements are arranged in heat transfer relation with the shell walls. A plurality of support pillars in the heatpipe chamber support the first surface against deformation when the same is subjected to molding pressures in the operation of the mold part in a mold cycle. The pillars can be hollow sintered inert metal columns filled or lined with a supplementary wicking material or hollow metal perforated tubes. The perforated support tubes also act as a dispersing nozzle or nozzles for the incoming liquid phase charge fluid entering the chamber from a supplemental charge fluid pumping system, or they may act as charge fluid liquid phase evacuation outlets from the heatpipe chamber to the supplementary pumping system. In an alternate embodiment a side-by-side nest of a plurality of pre-made heatpipe elements form an array having lateral dimensions at least generally co-extensive with the lateral dimensions of the first surface of the half mold part when finished. The array of heatpipe elements are encapsulated with a mold-forming material having the mold-cavity-defining first surface.

Title: Poxvirus-based expression vectors containing heterologous inserts derived from lentiviruses
Inventor: TARTAGLIA JAMES
IPC: A61K39/00
Filed: 1997-11-07
Abstract: Recombinants containing and expressing lentivirus, retrovirus or immunodeficiency virus DNA and methods for making and using the same are disclosed and claimed. In an exemplified embodiment, attenuated recombinant viruses containing DNA encoding a feline immunodeficiency virus epitope such as an antigen, as well as methods and compositions employing the viruses, expression products therefrom, and antibodies generated from the viruses or expression products, are disclosed and claimed. The recombinants can be NYVAC  or ALVAC recombinants. The DNA can encode at least one of: Env, Gag, Pol, or combinations thereof such as Gag and Pol or protease or Env, Gag and Pol or protease. The recombinants and gene products therefrom and antibodies generated by them have several preventive, therapeutic and diagnostic uses.  DNA from the recombinants are useful as probes or, for generating PCR primers or for immunization. The immunogenicity and protective efficacy of immunization protocols involving ALVAC-FIV and priming with a recombinant canarypox virus ALVAC-FIV followed by a booster immunization with inactivated FIV-infected celled vaccine (ICV) was evaluated against FIV challenge in cats and the protocol was shown to effectively induce FIV-specific protective immune responses. Further, it was found that immunized cats were fully protected from an initial challenge with a slightly heterologous FIV strain (50CID50) and were partially protected from a second challenge with a distinctly heterologous FIV strain (75CID50) given eight months after the initial challenge without any intervening booster.

Title: High offset bits with super-abrasive cutters
Inventor: SIRACKI MICHAEL ALLEN
IPC: E21B10/52
Filed: 1999-11-04
Abstract: A roller bit is provided having super-abrasive inserts on cutting portions to assure that the bit will maintain cutting efficiency. In the described exemplary bits, the axes of the roller cones are also offset by a significant or "high offset" amount from the central longitudinal axis of the bit, thereby providing for increased shearing and grinding action by the bit. The use of high offset in combination with super-abrasive inserts provides for optimal bit cutting designs which provide increases in ROP while preserving the bit's ability to hold gage and remain durable to achieve acceptable footage. Minimum high offsets and preferred high offsets are described for various bit sizes, designs and nomenclatures, including milled tooth bits and insert-type bits designed for use in soft-through-medium formation hardnesses as well as formations with greater hardnesses.

Title: Compounding assembly for nutritional fluids
Inventor: HITCHCOCK JAMES R
IPC: A61M5/142
Filed: 1999-08-12
Abstract: A mixing assembly (10) which transfers a number of nutritional fluids (20) from individual source containers (16) into a collection container (18) while noninvasively sensing the type of fluid being transferred is provided. The mixing assembly (10) utilizes a transfer set (14) to establish fluid communication between the source containers (16) and the collection container (18). A sensing assembly is configured to noninvasively sense a number of the types of fluid flowing through the transfer set (14) to help to prevent improper mixing. For other fluids for which the sensing assembly (200) alone may not be able to distinguish with the desired accuracy, the mixing assembly (10) utilizes a method to approximate the flow rate of that fluid with the flow rate also providing an indication of that type of fluid. By combining the output of the sensing assembly (200) with the flow rate determination, additional fluids can be identified. The assembly (10) includes a controller (41) that executes a number of routines that minimize the occurrence of false alarms, while insuring accurate and reliable compounding of prescriptions.

Title: Light fixture management system
Inventor: JEFFERY R CLARK
IPC: G06Q50/00
Filed: 2000-04-28
Abstract: A light fixture management system which tracks the location, history and operating characteristics of light fixtures in a structure or a group of structures and surrounding premises. Each light fixture is assigned indicia, for example a bar code, which is stored in a database in association with details of the light fixture. An observer charged with identifying light fixtures in need of repair carries a portable scanner. The observer scans the bar code associated with any light fixture in need of repair and optionally enters into the bar code scanner any observable problem. The scanned information is downloaded into a computer, which may be programmed to establish a repair route for fixtures identified as being in need of repair, based on the locations of the light fixtures and types of problems identified by the observer. Reports can be generated as required with any other desired information. The invention considerably simplifies the task of tracking light fixtures and substantially increases the efficiency and effectiveness of repair personnel. The master database may also contain the location of the circuit breaker which controls power to each fixture, to enable repair personnel to quickly locate and deactivate the circuit if necessary for a particular type of repair.
