Title: Strong pcr primers and primer cocktails
Inventor: HILL JANET ELIZABETH
IPC: C12N15/11
Filed: 2006-06-07
Abstract: The invention disclosed relates to a PCR primer pair for amplication of chaperonin-60 (cpn60) targets having high G+C content and to a PCR primer "cocktail" to improve the representation of diverse sequences in chaperonin-60 based PCR product libraries derived from complex templates. In previous cpn60-based and 16S rDNA-based studies of mammalian intestinal microbiota, it has been observed that some classes of organisms such as the Actinobacteria, which are known through culture-based studies to be present in large numbers in these environments, are underrepresented or even absent from PCR product libraries. Using library sequence data and reference cpn60 sequence data from cpnDB, the chaperonin sequence database, we designed a pair of PCR primers which can be used alone for higher G+C content targets and, when used in combination with a previously developed degenerate, universal cpn60 primer pair, improve the representation of complex templates with high G+C content. We have validated these primers using a combination of traditional and quantitative real-time PCR on both artificially contracted complex templates and biological samples. The development and optimization of this primer cocktail represents a significant advance in our ability to generate cpn60 PCR product libraries which more closely represent the biodiversity in complex microbial communities.

Title: Method and apparatus for locating a person who has been buried alive
Inventor: KAMPEL GERALD
IPC: G01S11/06
Filed: 2006-07-18
Abstract: A search apparatus and related method facilitate the final stage of a search for a buried person carrying a transmitter. When the searcher is in the close vicinity of the buried transmitter, the search enters a point-localization phase where the apparatus displays a representation of the current target distance from the apparatus to the buried transmitter as well as a representation of a previously-stored value for the target distance. By comparing the current distance to the previously-stored distance, the searcher can readily see whether the apparatus is getting closer to the buried transmitter or further away. Preferably, graphic symbols are displayed to represent the current distance and the previously-stored distance. The display can also provide a representation of whether the current distance is greater than or less than an immediately preceding distance that has been stored.

Patent CA-2577585-A1 (CA)
Title: Heat regenerative engine
Inventor: SCHOELL HARRY
IPC: F01K23/06
Filed: 2005-09-14
Abstract: A heat regenerative engine uses water as both the working fluid and the lubricant. In operation, water is pumped from a collection pan and through a coil around a cylinder exhaust port, causing the water to be preheated by steam exhausted from the cylinder. The preheated water then enters a steam generator and is heated by a combustion chamber to produce high pressure super heated steam. Air is preheated in a heat exchanger and is then mixed with fuel from a fuel atomizer. An igniter burns the atomized fuel as the flames and heat are directed in a centrifuge within the combustion chamber. The speed and torque of the engine are controlled by a rocker and cam arrangement which opens a needle-type valve to inject high pressure super heated steam into a cylinder having a reciprocating piston therein.
