Abstract: La présente invention se rapporte à un trépan à percussion (10) servant à percer des trous de forage et constitué par un corps en acier (12), un organe situé à chaque extrémité du corps servant à raccorder le foret à une unité de percussion telle qu'un marteau fond de trou ou un train de sonde d'une foreuse pneumatique, une pluralité de pièces rapportées encastrées dans l'autre extrémité du corps en acier. Les pièces rapportées périphériques ou pièces alignées de calibrage ont un corps en carbure métallique dont une partie de fixation arrière est encastrée dans le corps en acier et dont une extrémité avant fait saillie du corps en acier. Une couche de diamant polycristallin recouvre l'extrémité avant du corps en carbure. La couche comporte un bord situé à proximité du diamètre maximum de la pièce rapportée. Le bord (22) est maintenu à l'écart à une première distance (L1) de la paroi du trou de forage au cours du perçage grâce à l'inclinaison de la pièce alignée de calibrage (16) à un angle aigu (a) allant de 41· à 51· par rapport à l'axe de rotation (11) du trépan (10). L'invention se rapporte également à une pièce rapportée de calibrage, à l'utilisation d'une pièce rapportée recouverte de diamant servant de pièce de calibrage dans un trépan et à un procédé de maintien du diamètre d'un trépan au cours du forage à percussion pratiqué dans la roche en place.

Title: Fire prevention device for electric cooking stove
Inventor: RAK JOSEF
IPC: G05B9/02
Filed: 1997-12-19
Abstract: It is therefore a particular object of the present invention to provide the means of reducing cooking related fire hazards without compromising usability of electric stoves.      The present invention is designed to automatically shut down the burners of electrical stoves if the stove is left unattended for longer than a preprogrammed period of time.  A combination of a programmable timing device and a motion sensor is used for this purpose. The motion sensor monitors any human movements in the surroundings of the stove.  Should the motion sensor detect any inactivity in the immediate surroundings of the stove, the timing relay is activated to cut OFF the power supply to the stove burners after a preprogrammed period of time elapses.  In the case that the motion sensor detects human movements around the stove, the device will turn ON the stove's burners again until another period of inactivity is detected and the cycle will be repeated.

Title: A specific and sensitive method to detect prpsc in peripheral blood using a capture-immunosorbent assay-polymerase chain reaction (prp-immuno-pcr)
Inventor: TETRO JASON ANTHONY
IPC: C12Q1/68
Filed: 1998-06-23
Abstract: Currently, there is no method to identify with high specificity and sensitivity, the prion proteins (PrP sc) that lead to the development of the human diseases, Cruetzfeldt-Jakob Disease (CJD) and new variant CJD (nvCJD), also known as bovine spongiform encephalopathy (BSE). The invention is such a diagnostic assay and hereforth defined as PrP-Immuno-PCR. The method involves the combination of two well-described techniques to detect as little as one infectious unit from whole blood using monoclonal antibodies specific to the disease-causing prion proteins and the polymerase chain reaction to amplify such signal using a novel antibody-DNA complex. The method also differentiates the infectious prion PrP sc from a non-infectious cellular prion protein (PrP c) which is found in all healthy individuals.

Title: Pneumatic seed delivery system
Inventor: MEYER BRADLEY J
IPC: A01C7/04
Filed: 1998-07-15
Abstract: A pneumatic seed delivery system is provided, including a bin with a plenum at the bottom separated from the bin by a membrane to permit the upward flow of air from the plenum into the bin, and a tube extending through a side wall of the bin to provide fluid communication from an outer surface of the bin to an inner surface of the bin. One end of the tube is disposed inside the bin and adjacent to the screen, and a second open end of the first seed distribution tube is disposed outside the bin. In this manner, seed in the bin can be propelled up the tube by forcing air into the plenum, passing the air through the membrane and through seed located between the membrane and the first open end of the tube. This seed will then move up the tube and be carried to a remote location for use. This structure may also be provided by modifying a bin with an existing metering system removable through an opening in the bottom of the bin by removing a cover from the opening, removing the metering device, and inserting a device having plenum and tube structures into the opening.
