Abstract: Composition for and method of selectively controlling weeds in cereals Abstract The invention provides a herbicidal composition for the post-emergence selective control of grasses and weeds in cereals, such as wheat and barley. The composition contains two active components, one of which is N-(3-trifluoromethyl-1,2,4-thiadiazolyl-5)-N'-methyl-N'-methoxy urea and the other is a dichloropyridyloxy-.alpha.-phenoxypropionic acid derivative of the formula   wherein X is oxygen or sulfur and R is hydrogen, a cation, a lower alkyl, alkenyl or alkynyl radical. The invention also provides a post-emergence method of selectively controlling grasses and weeds in crops of cereals, such as wheat and barley, which comprises the use of this composition. In particular wild oat species are selectively controlled.

Abstract: ABSTRACT OF DISCLOSURE         A device for the extraction of capillary blood com-prises a plastic capillary open at both ends. The capillary is of predetermined volume and has a capillary effect at least at its front end. A holder which is provided with one or more windows is integrally connected to said capillary.       For avoiding dosage errors air exit apertures of restricted size are provided at the rear end of the capillary.          These air exit apertures are realized either by the use of a suitably profiled closure pin or by one or more openings in a transverse wall at the rear of the capillary. The air exit apertures reduce the size of the blood lobe which forms at the rear end of the capillary thus reducing dosage errors resulting from variation in the size of this blood lobe.

Abstract: ABSTRACT OF THE DISCLOSURE An electrical raceway for installation in an illuminated sign box of the type having a translucent sign panel is in the form of an elongated and hollow structure which provides reinforcement for such a sign box and a housing for electrical conductors.  Such raceway has a cover having two series of knock-out discs for mounting both left-handed and right-handed lighting fixture receptacles and has a channel having bottom and side walls, with reinforcement ribs in the side walls which cooperate with suitable complimentary ribs in the side flanges of the cover to provide strength, as well as a snap-on fastening for the cover.  When such raceways are installed in a sign box, the lighting fixture receptacles can be mounted so that the lighting tubes extend between two such raceways completely across one of the series of knock-out discs in each such raceway thereby improving the overall illumination of the translucent sign panel, and reducing the patches of varied light intensity.

Abstract: ABSTRACT OF THE DISCLOSURE A linear motor which utilizes the magnetic attraction between a washer formed from a ferrous material, e.g., steel, and a magnetic pole of an armature for automatically returning the armature to its original position upon the deenergization of a field coil.  The washer is originally located in alignment with and in surrounding relation to one of the effective poles of the armature.  The stroke of the armature is limited to a distance which insures that at the end of the stroke the one effective pole will be located closer to the washer than any other effective pole.  Upon deenergizing the field coil, the magnet attraction between the one effective pole and the washer will cause the armature to return to its original position.

Abstract: TITLE OF THE INVENTION         LOCK WITH IMPROVED PROVISIONS FOR      WITHSTANDING FORCES APPLIED TO BOLT                  ABSTRACT OF THE DISCLOSURE           A door lock including a bolt connected by a link to an actuator mechanism by which it is movable within a housing between a retracted position and an extended position.   A pin and slot connection between the bolt and link form a coaction mechanism that causes a prong on the link to engage an abutment on the housing when a force is applied to the extended bolt in the direction of its retracted position.   As the link pivots,a second abutment on the housing is engaged to further resist bolt movement.   The force is then absorbed by the housing rather than the more fragile actuator mechanism.   If the bolt is subjected to a force that would tend to pull it from the lock, the link engages another abutment on the housing to retain the bolt.           The bolt is movable a short distance from its normal extended position by compressing a spring without transmitting to the link the force applied to the bolt.  A hardened security pin within the bolt normally transmits the spring force to the link to avoid looseness.
