Abstract: GRAIN DRILL SUSPENSION SYSTEM                         Abstract A grain drill suspension system including a support member comprising a parallelogram link structure and a walking beam member.  The walking beam member has furrow cutting discs attached to a front portion thereof and a press wheel attached to a rear portion thereof.  The support member includes parallel vertical members and cross links.          The walking beam is pivotally connected at a medial portion thereof to a rear vertical member of the parallelogram structure.  A front vertical member is attached to a vertically adjustable attachment member associated with the suspension system.  A first spring extends upwardly from a rear portion of the walking beam to the rear vertical member biasing the furrow cutting discs downwardly.  A second spring cooperates with the front vertical member and the cross links resiliently urging the rear vertical member and walking beam downwardly.  The springs, along with the position of the front vertical member, cooperate to determine the depth of the furrow cut by the furrow discs.          The parallelogram support structure allows the furrow cutting discs to follow undulating terrain while maintaining a constant desired depth of the furrow.

Abstract: Abstract An elastic mounting for the rod-shaped insert tooth of a circular saw on a blade body.  The problem addressed is to eliminate loosening and disengagement of teeth caused by an impact-like loading on the teeth, which often occurs after a relatively short service life.  A blade body or a tooth is provided with an elastic strip whose spring force, together with the flattening force exerted by a locking rivet, urges the tooth against those points in its fitting notch which also receive the bearing forces exerted by a shearing force of the sawing action.

Abstract: ABSTRACT     A tool holder for a numerically controlled machine tool, in which a cutting edge provided on a base member is ad-justable with respect to a reference surface on the base member by adjustment means. The adjustment means comprise a U-shaped slot in the base member. This slot serves to form a pair of lever portions in the material of the base member, which lever portions are connected to each other by an area of the base member serving as a pivot. An ad-justment screw threadingly engaging the base member acts upon the free end of one of said lever portions such that upon an adjusting movement of the adjustment screw the first lever portion is deflected in a predetermined direc-tion to thereby deflect the second lever portion in the opposite direction. The second lever portion transmits its movement to the cutting edge by means of a spacing member disposed in the slot (Fig. 1).

Abstract: ABSTRACT OF THE DISCLOSURE    A transportable bagging apparatus for continual, sequential loading of individual bales of agricultural products such as, grass, alfalfa, corn stalks, hay, etc., into a plastic tubing.         The apparatus can be towed by an ordinary farm tractor or other vehicle, and can be loaded with any fork-type bale carrier or loader.  A removably mounted bracket delivers plastic tubing from a roll over one of opposite open ends of a vertically positioned, pivotally mounted drum on the apparatus.  When the entire roll of plastic tubing is gathered over the drum outer surface and tied over one of the drum's opposite open ends, the drum is then pivoted to a horizontal operating position with the opposite open end facing a bale engaged by a carriage.  The engaged bale activates a hydraulic cylinder to force a telescoping ram against the opposite face of the carriage.  This causes the engaged bale to enter the drum and load into the plastic tubing.  A dropgate extension on the carriage ejects the last bale from the drum to clear the apparatus.

Abstract: ABSTRACT                    INFRARED OPTICAL SYSTEM          A forward looking infrared optical system comprises a refractor telescope in combination with a powered window and fold mirror arrangement.  The arrangement comprises a powered window element with concentric spherical refractive surfaces having their common centre of curvature on the common optical axis where the latter is folded by the reflective surface of the mirror element.  Because the window element is powered it introduces significant spherical aberration and some colour aberration to the system.  However, the telescope provides compensation for such aberrations by being non-afocal and non-diffraction limited.  This is achieved by the objective system of the telescope being telephoto and formed of first and second elements of which the first element is positively powered and the second element is negatively powered and colour corrective.  The refractive surfaces of the second element are each spherical whereas at least one refractive surface of the first element is aspheric.  The second element is made of a material having a lower refractive index than that of the first element.

Where Cartesian coordinates is assumed having an origin in the center of the planar surface of the array antenna, an X-axis extending in a vertical center axis of the array antenna, a Z-axis extending in a direction perpendicular to the planar surface through the origin, and a Y-axis, extending in a direction perpendicular to the X- and Z-axes through the origin, the shaped beam antenna is characterized in that the longitudinal axis of each reflector segments is in parallel with the X-axis, the main reflector is symmetrical with respect to the X-Z plane and formed convex in a negative direction of the Z-axis, and each radiating element is disposed so that its excitation amplitude is symmetrical with respect to the Y-Z plane and its excitation phase is antisymmetrical with respect to the Y-Z plane, whereby a radiation beam formed by the main reflector is symmetrical with respect to the Z-axis on the Y-Z plane and is asymmetrical with respect to the Z-axis on said X-Z plane.  Thus, with this antenna, a good beam shaping performance and an excellent cross polarization discrimination can be obtained.
