Title: Mecanisme a leviers et a embrayages pour vehicule a traction humaine
Inventor: CHARBONNEAU PIERRE
IPC: B62M1/24
Filed: 1996-01-10
Abstract: Le vélo traditionnel utilise un vilebrequin en guise de pédalier, afin de transmettre l'énergie humaine à la roue de traction. L'utilisation de ce vilebrequin ne permet de communiquer qu'une partie de la force appliquée. De fait, sur une course de 360 degrés, seulement 90 degrés contribuent à générer cette force. La présente invention est un principe mécanique mieux adapté aux mouvements de balancier du corps humain. En effet, ce mécanisme constitué de leviers et de roulements à embrayage à rappel sert à transformer un mouvement de va-et-vient en mouvement de rotation qu'il transmet à un système traditionnel de transmission via un axe de transmission.

Abstract: The counting disk (1) has circumferential sections (2) arranged on its border, and each circumferential section has a suction hollow (4) in which suction openings (5a to 5f) located one behind the other are arranged. Upon rotation of the counting disk, said suction openings are connected intermittently to a suction-air source, with the result that the corners of a sheet stack, one after the other, are subjected to suction, deformed, separated from the rest of the sheets and, by virtue of a pneumatic counting pulse being produced, counted. The suction air is supplied to the suction openings (5a to 5f) via a duct (6, 7) whose section (7), which opens into the suction openings, is directed perpendicularly with respect to the plane of the counting disk. Moreover, the suction openings (5a to 5f) are located in the center of the suction hollow (4).

Title: Method and apparatus for digital processing in a global positioning system receiver
Inventor: LITTON JAMES DANIEL
IPC: G01S1/00
Filed: 1995-02-28
Abstract: A Global Positioning System (GPS) commercial receiver including a digital processor disposed to utilize the energy of both the L1 and L2 GPS satellite signals in order to derive an estimate of an unknown security code used to modulate the signals. In processing the signal energy from the received L1 and L2 signals in accordance with statistical Maximum A Posteriori (MAP) estimation theory, the received L1 signal is correlated with a locally generated replica of the P code, and passed through a bandpass filter having a bandwidth approximating the bandwidth of the unknown modulation code. The received L2 signal is similarly correlated and filtered, and the decorrelated signals are then latched in such a way as to account for the differential ionospheric refraction of the L1 and L2 signals. The bandlimited L2 signal is used to produce quadrature error signals related to phase difference between the L2 signal and a locally generated L2 replica. The error signals are integrated over an integration period which approximates the bit period of the unknown code, with the resulting estimates of the bits of the unknown code being combined with corresponding L1 channel code bit estimates weighted by a factor proportional to the difference in received L1 and L2 signal power. The hyperbolic tangent of each combined W-code bit estimate is then computed, with the result being multiplied by one of the integrated error signals. The resulting control voltage is then used to adjust the locally generated L2 carrier phase.

Patent CA-2191176-A1 (CA)
Inventor: WEBER WOLFGANG
IPC: B23B51/05
Filed: 1996-11-25
Abstract: A boring apparatus which includes a rotatable cutting head used to cut a hole in a workpiece.   The cutting head is mounted on an axially movable support, and is rotatable about and reciprocally movable along the axis between a forward cutting position, to engage and cut the workpiece,  and  a  rearward  position  spaced  from  the workpiece.  Cutting is performed by a cutting blade which is spaced radially from the axis, and which is movable relative to the rest of the cutting head by a blade advance mechanism.   During cutting operation, the blade advance mechanisms move cutting blade both forwardly and radially inwardly through the workpiece wall, in the same direction at which the blade is inclined.  The hole is thus formed by lowering the cutting head and then rotating the cutting blade as the blade advance mechanism moves the blade at an angle through the workpiece.  Both the resulting hole and waste plug cut from the workpiece produced by the angled movement of the blade have complementary tapered edge portions, with the result that the plug will have a portion with a diameter which is larger than the smallest diameter portion of the hole.

Title: Fumonisin-detoxifying enzymes
Inventor: DUVICK JONATHAN
IPC: A01N63/50
Filed: 1995-08-11
Abstract: Methods for identifying organisms capable of degrading fumonisin. Fumonisin can be incorporated into culture medium for selection of organisms resistant to fumonisin and/or capable of growing on fumonisin as a sole carbon source.  Using this method, several organisms have been identified. These organisms can be used to isolate the enzyme and the gene responsible for conferring fumonisin-resistance. The gene can be cloned and inserted into a suitable expression vector so that the protein can be further characterized.  Additionally, the DNA encoding for fumonisin-resistance can be used to transform plant cells normally susceptible to Fusarium or other toxin-producing fungus infection. Plants can be regenerated from the transformed plant cells. In this way, a transgenic plant can be produced with the capability of degrading fumonisin, as well as with the capability of producing the degrading enzymes. Methods for detoxification in grain processing and in animal feed and rumen microbes are also disclosed.
