Abstract: A vehicle external rear view mirror assembly comprising a frame, a mirror secured in frame, a base for securing the frame with the mirror to a vehicle body, a lever assembly for rotatably connecting the frame with the mirror to the base, and an articulation assembly for pivotally attaching the frame with the mirror to the lever assembly.
Abstract: A web of paper, cardboard, foil or textile material is pulled against and between two rotary knives which sever the web longitudinally and form a slot as well as dust. Such dust is removed by a pneumatic mechanism having one or more nozzles which discharge one or more streams of compressed ionized air against the upper side of the web in the region of the slot, and a suction chamber disposed beneath the path for the web, extending across the slot beneath the nozzle or nozzles, and having one or more suction ports which enable the chamber to collect the particles of dust. The port or ports further enable the chamber to collect those fragments of the web which adhere to the separated sections of the web in the region of the slot between such sections.
Abstract: The invention relates to a polymeric anhydride of magnesium and proteic ammonium phospholinoleate having the following distribution of components expressed in percentage of magnesium (20.1.+-.0.9%), Ammonium (10.0.+-.3.3%), Phosphate (45.2.+-.2.7%), linoleic acid (11.6.+-.4.3%), total protein (0.49.+-.0.07%) with the presence in percentage of the following aminoacids: Aspartic Acid (7.19%), Threonine (3.56%), Serine (7.56%), Glutamic Acid (8.53%), Proline (0.5%), Glycine (9.69%), Alanine (7.46%), Valine (1.0%), Methionine (4.38%), Isoleucine (2.54%), Leucine (3.03%), Thyrosine (0.5%), Phenylanine (1.0%), Histidine (2.83%), Lysine (3.56%), Tryptofan (1.3%) and Arginine (35.2%).This compound is produced from a selected line of Aspergillus sp in culture of oat schaff and bouillon at the temperature of 30.degree./35.degree. C., pH 3-4 with low aeration (10 l/m) and agitation (40 rph) restricted to the first 48 hours of the producing process.

Abstract: A photopolymerizable composition comprising(a) a monomeric componment which is a half acryloyl ester of bisphenol A epoxy monomer;(b) an initiating system activated by actinic radiation; and(c) a preformed macromolecular elastomeric polymer binder.
Abstract: Polyester and polyamide membranes having improved permeation properties are disclosed. The membranes are derived from t-butyl-substituted isophthaloyl halide, in particular, 5-t-butylisophthaloyl chloride. The t-butyl-substituted isophthaloyl chloride can be employed with monomers such as diols and diamines to provide polyesters and polyamides with improved permeation properties.
Abstract: Spinnable dopes containing fiber-forming polymers being at least about 55% and less than about 80% lyotropic polysaccharide and at least about 20 percent and less than about 45% thermally-consolidatable polymer and a process for making oriented, shaped articles of lyotropic polysaccharide/thermally-consolidatable polymer blends by orienting the dopes and removing the solvent.
Abstract: A centrifuge rotor has a continuous annular groove disposed radially outwardly of each of the sample receiving cavities provided in the rotor. The groove collects any liquid spilled during operation of the rotor thereby to prevent the liquid from draining into the cavities and contaminating the same as the rotor slows.
Abstract: A content-addressed memory system stores large amounts of data for quick access by keyword value combinations. The system comprises a controller and a plurality of content-addressed memory chips. Each chip comprises a plurality of word cells with logic to enable independent, parallel operation of each word cell, storage of a record of closely related data in more than one word cell, and accessing an entire record when data in one word cell is matched to the keyword value.
Abstract: A stabilizer compound for synthetic resinous materials is a tri-substituted triazine in which each substituent is a N.sup.4 -methylated 2-keto-1,4-diazacyclohexane connected to the triazine ring through an alkylene bridge. This bridge permits efficient methylation of the N.sup.4 atom in every substituent under conditions which yield crystals having at least 90% purity. These crystals may be further purified to at least 95% purity at which purity level they contain less than 500 ppm ash. The stabilization effect of 95% pure compound in a polyacetal is such that, even with an ash content of 50 ppm, it has better stabilization properties than its 99.2% pure precursor (the non-methylated tri-substituted triazine) with an ash content of 10 ppm, as evidenced by lower formaldehyde evolved and better color retention, that is, developing less color in a water white sample after testing at 259.degree. C.

Abstract: This invention relates to a process for reducing odor perceived by a nearby community from an odor-emitting system, e.g., sewage treatment, etc., by adsorbing on core particles, as described, condensible components present in the system. The malodorous components then cannot adsorb in a film of condensible components on the aerosol to be carried by the aerosol plume into the surrounding community, but remain with the humid gas plume to be dispersed upward into the atmosphere. The process is useful for any system which contains condensible components and malodorous components and whose emissions form aerosols.
