Title: Device for fixing the knives of rotary mowers
Inventor: BOUET JACQUES E
IPC: A01D34/44
Filed: 1978-01-25
Granted: 1980-05-27
Abstract: ABSTRACT OF THE DISCLOSURE     A device for fixing knives on the rotary cutting element of a mower, wherein each knife is capable of moving with respect to the  cutting element in a substantially radial direction and is subjected to the centrifugal action of elastic means.  The knife is endowed with a sufficient degree of rigidity for the cutting operation, with the result that the knife can have a smaller thickness than conventional pivoting knives and can consequently be lighter in weight.          If the knife encounters an obstacle, the elastic means yield temporarily and the knife then returns to its initial position without having sustained any damage.

Abstract: A HOMOKINETIC JOINT ALLOWING A LARGE               ANGULAR DISPLACEMENT.            ABSTRACT OF THE DISCLOSURE    The joint comprises a first member defining a tripod connected to a first shaft and forming three trunnions. Part-spherical rollers are respectively slidably and rotatably mounted on the trunnions. A second member connected to a second shaft defines three raceways in which the rollers are received. The raceways are each formed by a pair of part-circular sectioned grooves the mean line of which is an arc of a circle centered prefera-bly in the vicinity of the axis of the second shaft. The tripod is rigid with a shaft section which has, in a zone close to the tripod, a substantially triangular cross-sectional shape approximately constituting the envelope of the free edge of the second member when the joint operates with an angular displacement of the first and second shafts close to the maximum possible angle.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention discloses several optical fiber cable constructions which basically disposed the optical fibers in a loosely-fitting fashion in respective longitudinal compartments provide by splicing tapes folded or shaped to a designated trans-verse cross-sectional shape.  The loose fitting of the optical fibers overcomes the increased transmission losses and changed transmission bandwidth caused by lateral or compression forces inherently applied to the optical fibers of conventional optical fiber cable constructions.  Two methods and apparatus for fabri-cating the optical fiber cable constructions are also disclosed. In one embodiment, the assemblage die is stationary with respect to the rotary cage and the guide plate, whereas in the second embodiment the assemblage die is mounted to rotate with the rotary cage and the guide plate.  In both case tape folding process and fiber accommodation therein and assemblage are achieved in tandem or in one operation.

Abstract: OVEN HINGE MECHANISM INCLUDING CAM BALANCE MODIFIER            ABSTRACT OF THE DISCLOSURE         A hinge mechanism is provided for use with an oven housing having side walls, a rear wall, an access opening opposite the rear wall and a door for the access opening wherein the door is movable through a plurality of positions between a closed position and an open position.  The hinge mechanism includes a bracket rigidly mounted to the side wall of the oven structure for pivotally securing the door to the side wall of the oven housing.  The bracket includes a specifically designed camming surface along the top edge.  A lever is pivotally secured to the door and includes first and second arm members. A spring having first and second ends is provided for biasing the lever toward the side wall of the oven housing.  The first end of the spring is attached to the first arm member of the lever, and the second end of the spring is attached to the side wall of the oven housing adjacent the bracket.  The second end of the lever includes a cam follower for engaging the camming surface of the bracket.  The lever acting on the camming surface is operative to counterbalance the door so that the door can be balanced at desired positions between the door closed and open positions, and so that the door can be maintained in an unbalanced state at the ends of the door swing.          The counterbalancing effect of the lever increases as the door moves from the door closed position to the door open position to match the force delivered by the spring as the spring extends due to the door moving from the door closed position to the door open position.

Abstract: ABSTRACT OF THE DISCLOSURE A dynamic memory element is disclosed which is constructed on a doped semiconductor substrate.  A strip-shaped semiconductor region, which is on a surface of the substrate and which is doped opposite to the substrate, is designed as a first selection line, whereas a path which is separated by means of an insulating layer from the substrate, and which runs cross-wise to the strip-shaped region, represents a second selection line.  The path is separated from a substrate region which lies next to the strip-shaped region by means of a thin film region of the insulating layer.  In the case of memory elements of this type, simple construction and small dimensions are desired.  According to the invention, this is achieved in that inside of the strip-shaped region, an island-shaped semiconductor region doped oppo-site to the strip-shaped region is arranged and which lies close to an inter-face of the strip-shaped region separating it from the semiconductor region which lies under the thin film region.  The invention is useful in digital semiconductor memories of high bit density.

Abstract: IMPROVED MAIL SORTING MACHINE                     Abstract of the Disclosure The mail sorting machine of the present invention is capable of receiving a supply of envelopes in a magazine from which the individual envelopes are picked off in succession by means of a suction device operating in combination with a pair of conveying belts having a friction surface facing the incoming envelopes.  The suction device acts through holes in the conveying belts to draw the lead envelope against the friction surface of the conveying belts for separation of this envelope from the rest of the supply.  The separated envelope is then transferred to a read station where a reading device reads a sort code imprinted on the envelope.  The envelope is then provided to the storage section of the machine where it is directed to its designated sorting bin.  The storage section of the machine is provided with a plurality of diverter mechanisms which are arranged in pairs to form a guideway through which the envelopes are directed.  As an envelope approaches its designated sorting bin, the diverter mechanism associated with this bin is activated.          Activation of the diverter mechanism causes its deflector gate to be interposed within the guideway to direct the approaching envelope into the sorting bin associated with the deflector mechanism.  Each sorting bin has a rib which runs along the floor of the bin to hold the envelopes in an offset position wherein the inherent vibratory motion of the machine causes the envelopes to be aligned in a neat stack.  Each sorting bin is also equipped with a biasing plate which serves to keep the envelopes stored within the bin in a vertical plane.
