Abstract: The invention is substituted 2,6-dinitroaniline compounds and preemergence herbicidal methods and compositions employing the substituted 2,6-dinitroaniline compounds.

Abstract: This invention relates to certain novel substituted 2,6-dinitroaniline compounds which are useful herbicides.

Abstract: This disclosure relates to a hydrant coupling device including a pressure control valve which, due to its portability, may be connected to any one of a plurality of hydrants to regulate the flow of liquid therefrom, and additionally including a pit valve which is interlocked with the pressure control valve body to prevent the spilling of liquid if the control valve is accidentally forced loose from the pit valve.

Abstract: This invention relates to certain novel preemergence herbicidal methods and compositions employing substituted 2,6-dinitroaniline compounds.

Abstract: This invention relates to certain substituted 2,6-dinitroaniline compounds. It further relates to certain preemergence herbicidal methods and compositions employing substituted 2,6-dinitroaniline compounds.

Abstract: This invention relates to 2-chloro-N-isopropyl 2',3'-dimethylacetanilide, a method for the preparation thereof, and a method for the control of undesirable plant species therewith.

Abstract: A card selector which comprises a cradle for receiving an assemblage of cards and with a mechanism for effecting vibratory movement of said cradle. The cards useful with said machine are provided with information receiving zones and with there being marginal perforations corresponding to such zones; those perforations relating to said zones having data entered therein opening through the adjacent edge of the card by means of a recess. Rigid elongated members are provided for extension through the aligned perforations along one margin of the cards in an assemblage thereof for suspendingly supporting same within said cradle whereby upon vibration of said cradle cards having the engaged perforations opening through the adjacent margin separate from the assemblage by freely dropping into the lower portion of said cradle.

Abstract: A composition for use in the manufacture of thermally insulating, refractory articles, containing particulate refractory material and from 1 to 20 percent by weight of fibrous organic material, for example paper fibers and/or cardboard fibers, is made with a plastic consistency. For example, the composition is made with a consistency or apparent viscosity of at least 200,000 centipoises at 25.degree. C. Methods of making the composition and for making articles from the composition are also described.

Abstract: The proof mass of a pendulous accelerometer is floated in a liquid metal such as mercury which has high surface tension and non-wetting characteristics within a specially designed cavity such that neutral bouyancy conditions are achieved for all principle axes except the input axis.

Abstract: Herbicidal compounds are disclosed having the general formula ##SPC1##Where X is hydrogen or hydroxy, R.sup.1 is hydrogen or halo and R.sup.2 is alkyl, cycloalkyl, phenyl, alkenyl, and substituted derivatives of the above. Compounds for which herbicidal usage is claimed may include, in addition to the compounds of formula (I), formula (I) compounds in which R.sup.2 is hydrogen.

Abstract: There is disclosed a vehicle transporting apparatus comprising a mounting for attachment to the rear of a transporting vehicle, a rearwardly extending boom one end of which is pivotally connected to the mounting for up and down swinging movement of the boom on the mounting, the free end of the boom having mounted thereon two supports for the wheels of a vehicle to be transported, which supports are spaced horizontally apart in a direction transverse to the direction of travel of the vehicle, power means connected to the boom to effect swinging movement thereof between a loading position where the supports rest on the ground, a transporting position where the supports are raised a short distance above the ground, and a stowed position where the boom extends upwardly from the mounting, and releasable detent means between the boom and the mounting to retain the boom in one or more of said positions.

Abstract: Stresses induced by differential expansion and contraction of the solid propellant grain and the rocket motor case to which it is conventionally bonded are obviated by bonding a special sheath to the propellant grain and attaching it to the rocket motor case only at its forward and aft ends. A thin layer of Teflon is confined intermediately between the sheath and the rocket motor case. The sheath is extended beyond the propellant grain and bonded to the case so that an unbonded section thereof extends between the zone at which it is bonded to the case and the propellant grain. The propellant grain joins the sheath by a surface fillet to relieve surface stresses at this juncture. A gastight seal is provided in the thrust nozzle of the rocket motor for pressurizing of the combustion chamber to inhibit radial shrinkage of the propellant.

Abstract: A vehicle load lifting and lowering apparatus, which can be used as a vehicle tail lift to lift and lower loads of up to 8 tons between the level of the ground on which the vehicle stands and the level of the vehicle's load carrying deck, comprises a pair of parallel spaced apart guide columns which can be swung via a deformable articulated linkage towards and away from the vehicle. Runners slidably mounted in equal numbers on each column support between them a load carrying platform, and hydraulic rams power the runners (and hence the platform) up and down the columns during load lifting operations.
