Patent CA-2013645-A1 (CA)
Inventor: ROBERT JEAN
IPC: F16H9/10
Filed: 1990-04-02
Abstract: In a variable speed transmission of the pulley type, one of the pulley cheeks is movable axially with respect to the other which is stationary. The movable cheek faces a reaction cup which is solid with the stationary cheek. The cup and the movable cheek are formed with converging cam surfaces which define between them a chamber into which are disposed centrifugal weights having ends sliding on the cam surfaces. When the pulley and reaction cup rotate, the weights are thrown outward and force the movable cheek toward the stationary one.     According to the invention, the cam surface of the reaction cup is concave, having a radius of curvature of predetermined length. On the other hand, the end edges of the centrifugal weights slidable on the cam surface of the reaction cup are convex and have a radius of curvature shorter than said predetermined length so that the ends of the weights bear only on a limited part of the cam surface of the reaction cup.

Title: Method for measuring a length and electronic slide caliper
Inventor: LORENZ MARCEL
IPC: G01B3/20
Filed: 1991-06-04
Abstract: A b s t r a c t A method and an electronic slide caliper serve for measuring a length. The slide caliper comprises a rule and a slide which is arranged on the said rule for longitudinal displacement and which is provided with two sensors which are offset relative to each other in the longitudinal direction in such a way that the zero passages of the signals generated by the sensors will not coincide. In order to be able to measure the lengths even in the presence of considerable drifts, the zero passages (ND) of the signals are determined by determining first maximum values (MX) and minimum values (MN) of the signal values (U) and deriving thereafter the zero passages (ND) as arithmetic mean value. By taking the average of a larger number of zero passages one then determines the respective zero level (UN) (Fig. 8).

Abstract: In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes to produce a relative orbital motion, a coupling for causing concurrent rotation and for enhancing the nutational stability of the scroll element.  In the preferred embodiment, the nutation reducing means is comprised of an Oldham-type coupling engaging extension members on one of the scroll end plates and drive keys on the other respective end plate.  The angular disposition thereof is optimized to cause the Oldham coupling to generate during rotation a moderating moment load in opposition to the tipping moment load of at least one of the scroll elements and thereby enhance the nutational stability of the scroll elements.  The moderating moment load of the coupling imposed on the scroll elements may be altered by varying the angular and radial disposition of the center of gravity of the coupling.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to genes for the production of virus resistant plants.  The gene encodes a sequence which can act as initiation sequence for the synthesis of a complementary RNA and which is subsequently coupled to an antisense sequence which allows a cap-independent translation in the sense orientation, and with an antisense sequence which encodes a protein which is destructive  to  the  metabolism  of  a  plant,  in  the  sense orientation.  After a virus has attacked the cell the RNA is transcribed into a complementary RNA by means of the viral replicase, or it is also possible that the RNA is transcribed into a complementary RNA by means of a replicase activated in the cell via a different mechanism and the information for a cell-destructive enzyme, which is now present in the sense orientation, is read off.
