Abstract: In the pot cover container-envelope combination for the presentation of cultivated plants, a container or pot in which the plant has been cultivated is placed inside an envelope and a means is provided for preventing any accidental disengagement of the container or pot from the envelope.

Abstract: Apparatus for dispensing and opening plastic bags from a continuous strip wound in a reel apt to detach from it a bag (4) at a time, open it and keep it open below a mouth (8) through which a customer may insert into the underposed bag (4) the items he purchased, the apparatus comprises also a scanner (5) connected through a computer (7) to a shutter (11, 11') located on the mouth (8) so that the computer (7) controls the opening of the shutters (11, 11') and the inhibition of the scanner (5) when it has registered an item, and controls the reactivation of the scanner (5) and the closing of the shutters (11, 11') when the registered item has entered the bag (4) through the mouth (8).

Abstract: Tough, high strength fibers of copolyesters from hydroquinone, isophthalic acid and 4,4'-oxydibenzoic acid in defined proportions.

Abstract: This invention concerns novel fluorine-containing diamines, polyamides and polyimides. The compounds are useful in the formation of moisture resistant films, fibers and shaped articles.

Abstract: This invention relates to certain herbicidal oxatricyclic ethers, agriculturally suitable compositions thereof and a method for their use as broad spectrum preemergent or postemergent herbicides.

Abstract: This invention relates to a process for cross-linking polymers that are crosslinkable by free radicals and/or contain aromatic rings by heating these polymers with a compound containing xanthene groups. The crosslinked polymers have improved chemical resistance.

Abstract: An imaging method and apparatus produces a film of photohardened composition by exposing a layer of photohardenable composition to actinic radiation through a surface of a barrier transparent to the radiation and in contact with the composition at an interface therewith. An inhibition layer is created within the photohardenable composition in contact with the interface that inhibits photohardening of the composition within the inhibition layer during exposure, thereby precluding adhesion of any photohardened composition to the barrier.

Abstract: Bulked continuous filament carpet yarns having high levels of bulk are disclosed. When ply-twisted together at unusually high twist levels and tufted into carpets, such yarns produce cut-pile carpets having a superior balance of carpet bulk and newness retention when compared to carpets of identical construction made with yarns having conventional levels of yarn bulk and/or twist.

Abstract: A process is disclosed for heating never-dried para-aramid fibers containing 20 to 200 wt % water, based on dry polymer weight to form a fiber having a modulus of greater than 800 gpd while retaining a high tenacity. The fibers are heated in one or more microwave resonant cavity applicators to a temperature of 250.degree. C. to 425.degree. C. and preferably 270.degree. C. to 310.degree. C. while under a tension of 0.2 to 10 grams per denier. The preferred para-aramid is poly(p-phenylene terephthalamide). Fibers having a density of less than 1.43 g/cc can be made; and fibers having moduli greater than 1100 gpd can be made.

Abstract: Preparation of polyester resins from dimethylterephthalate by forming bis(2-hydroxyethyl) terephthalate, and using a portion of this product as solvent for one or more dicarboxylic acids and one or more dihydric alcohols, reacting the acids and alcohols, and combining the portions, and polymerizing the mixture.

Abstract: The invention provides a process for enantioselective hydrocyanation of aromatic vinyl compounds which produces nonracemic mixtures of chiral, arylpropionitriles; novel carbohydrate phosphorus and nickel catalyst compositions; and optically pure (S)-(-)-2-(6-metehoxy-2-naphthalene)propionitrile.

Abstract: Preparation of ethylene copolymers from ethylene and polar and/or non-polar comonomers in the presence of selected nickel-containing catalysts.

Abstract: A device for driving the ring levers that control the keys of a high-speed rotary dobby. In the device, a metal rocker armature is hinged to each lever along the axis of symmetry of the device. The axis passes through the fulcrum about which the levers rock. The levers have at their lower ends teeth that cooperate with corresponding grooves in two digging tracks that move with a reciprocating motion and in mutual opposition perpendicular to the axis of symmetry. The upper rocker armature surface, moreover, cooperates with one of two overlying electromagnets that are arranged symmetrically about the axis of symmetry.

Abstract: 4,5,6,7-Tetrahydro-1H-imidazo[4,5-c]pyridine derivatives such as 1-(4-amino-3-methylphenyl) methyl-5-diphenylacetyl-4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine-6-car boxylic acid are useful for treatment of CNS disorders, such as cognitive and learning disorders, mediated by angiotensin-II.

Abstract: Antihypercholesterolemic activity, due to competitive inhibition of HMG CoA reductase, is exhibited by a compound of the formula ##STR1## m is 0 to 3; R is selected from:(1) alkyl;(2) substituted alkyl;(3) alkoxy;(4) alkenyl;(5) cycloalkyl;(6) phenyl; and(7) substituted aryl; andR.sup.1 and R.sup.2 are as defined in the specification.

Abstract: Improvements in polyester yarns of high strength from high viscosity polymer, obtained by melt-spinning such high viscosity polymer at high withdrawal speed to provide a novel intermediate partially-oriented yarn of high viscosity polymer, followed by drawing such intermediate partially-oriented yarn at the appropriate draw ratio to provide the desired high strength polyester yarn, especially of fine denier per filament to provide surprising advantages in durability as shown by an increased flex life, and if desired using a warp-drawing process to provide warp yarns of such high strength polyester, or a draw-texturing process to produce draw-textured yarns.

Abstract: A multidirectional propeller shaft bearing is disclosed which includes a body made of two die-stamped plates, the first being provided with a cylindrical box having an anchoring flange on one side and the opposite side has an attached, welded and equally shaped other flange made by the plate itself. In addition, within the cylindrical part, an equally cylindrical rubber part is housed, the inside diameter of which includes a core of harder material which is provided with a grease nipple. The core of harder material provides an inner housing for a conventional bearing so that any type of propeller shaft may be accurately passed therethrough, with multidirectional springiness being provided by the rubber part whose outside diameter forms a flange or collar shaped so as to fit closely against the anchoring flange and so that it may be affixed thereto by means of an equally shaped, die-stamped plate, attached by means of nuts and bolts, in an arrangement that resembles a sandwich.
