Abstract: This invention relates to a reading aid having substantially non-glare, with controlled directional light for restrictive light reading. The present non-glare night reader includes a plurality of lights disposed within the body of the reader, and about the peripheral edges thereof. In a preferred embodiment, the present non-glare reader includes a unitary frame and handle, the frame having either four or five sides each of which defines a perimeter of the night reader. In the five-sided embodiment, the reader has two perimeter edges disposed angularly such that when in combination with a receptive stand, the combination provides a convenient storage facility for the night reader. In both the four and five sided embodiments, there is disposed within the inner edge of the frame, a plurality of miniature light bulbs which are connected to a suitable source of electricity.

Abstract: Increased yields of enzymes, particularly tissue plasminogen activator (tPA), are produced from cells, particularly CNCM I-222 cells, by a process using less concentrated lectin, particularly concanavalin A, in culture medium added to replace initial growth medium than has been used hitherto. After first harvesting of enzyme in supernatants, the culture can be reactivated by the addition of fresh culture medium containing an even lower lectin concentration, and a further harvest of enzyme obtained. The two harvests of enzyme together can give a greater overall yield than a single harvest after a single induction step employing the conventionally used higher lectin concentrations. Enzyme yield can be further increased by repeating the last incubation step once or twice to obtain one or two further harvests.

Abstract: A vaccine against a DNA virus, for exmaple, Herpes simplex virus, is prepared by incubating a cell sample which has been infected with the virus, releasing the nuclei in the infected cell material from the cytoplasmic fraction of that material, chemically fixing the polypeptide chains in the cytoplasmic fraction, and forming a precipitate which includes the virus antigens in the cytoplasmic fraction, the precipitate providing the active constituent of the vaccine. A characteristic strain of the virus is preferred, and transfers its characteristics to the vaccine so that vaccinated subjects may subsequently be distinguished from infected subjects.

Abstract: This invention relates to an automatically controlled water bouyant pollution-skimmer-and-recovery system which collects lighter than water contaminants in a simple efficient manner such that the contaminants are concentrated for either disposal or reuse while the water is rendered significantly pollution free and safe for return to the environment.

Abstract: A fishing boat having an integral tackle box is disclosed, the tackle box being customed positioned along the gunwale near the raised fore deck along the bow. The tackle box is disposed rearwardly from the raised fore deck, the integral tackle box having a height approximating the height of the raised fore deck.

Abstract: A method is presented for metal bonding of a base metal by creation of a weld puddle by means of an air cooled gas-tungsten-arc torch.As the puddle is created, the filler metal is fed as a wire into the puddle by means of a cold wire feed mechanism. The torch is automatically moved across the base metal in a longitudinal direction. The filler metal is deposited as the torch transverses the base metal. At the end of each stroke, the base metal is automatically indexed radially to the width of the weld bead. The process is continued until the bearing journal has been completely covered with filler metal to the required thickness.In a disclosed preferred method, the filler metal is a tin, antimony, copper babbitt alloy which is bonded to a bronze metal for bearings.

Abstract: The invention disclosed provides a paint can receptacle having a circular strip horizontally disposed to receive a paint can. A J-shaped ladder grip projects tangentially from the circular strip for rail engagement by the leg portion thereof. A first pivotal pin is positioned in the vicinity of the tangential union of the J-shaped ladder grip and the circular strip and joins a downwardly projecting vertical support member to the circular strip. A second pivotal pin is positioned diametrically opposite the first pivotal pin and joins the circular strip with a vertically disposed ladder rung gripping member intermediately therealong. The ladder rung gripping member has an arcuate terminal upper edge for rung engagement. A base support member is secured between the lower edge of the ladder rung gripping member and the lower edge of the downwardly projecting verticle support member thereby providing a support surface for the bottom of a paint can.

Abstract: The invention disclosed provides a new improved paint repellent composition and method of using same such as, for example, a coating in a spray booth. In particular, the present paint repellent composition includes a mixture of hydrocarbon oils, sodium chloride, sugar, aluminum silicate, sand and acetic acid and when applied to a substrate effectively repels paint.

Abstract: Patent discloses a method and an apparatus for the recovery of organic solvents from mixtures of organic solvents and polymers soluble or dispersible in the organic solvents. The method comprises the heating, by microwave radiation utilizing a magnetron type radiation source, of the mixture causing said mixture to reach the heat of flashing and/or evaporation of the solvent, collecting the solvent as it so vaporizes and recovering fresh solvent. The dry cake can be discarded or reused depending upon the extent of polymerization.

Abstract: The invention disclosed provides a new improved method and system for generating heat efficiently by means of frictional heat produced by a rotating impeller disposed within a closed housing which contains a heat transfer liquid and a gaseous layer. Rotation of the impeller generates heat as well as pressure in the system such that circulation of the heat transfer liquid may be readily effected through a closed conduit circuit to a heat dissipator. In a preferred embodiment, the rotating impeller is disposed within a diffuser which functions to increase the velocity of the heat transfer liquid and increase the static pressure within the system.

Abstract: The invention disclosed is for new improved hydrophobic polyurethane foams prepared by reacting a hydrophobic polyisocyanate reactant with large amounts of an aqueous reactant in the presence of an emulsifying agent. The resultant foams may be characterized with a broad spectrum of improved properties including load-bearing characteristics, hydrophobic properties, textural characteristics and the like.

Abstract: The invention disclosed relates to a method for using a new improved composition for inhibiting or preventing accumulation of scale or the like on heating surfaces in an aqueous system. The present composition includes an acrylic polymer, a water-soluble chelant, and an organophosphonic acid and/or their water-soluble salts. In a preferred embodiment, the composition is composed of sodium polymethylacrylate, nitrilotriacetic acid and hydroxyethylidene diphosphonic acid as its water-soluble salts.

Abstract: The invention disclosed is for a new and novel class of liquid polyene compositions formed of a molecule containing at least two unsaturated carbon-to-carbon bonds disposed at terminal positions on a main chain backbone of the molecule. The molecule includes unsaturated carbon-to-carbon bonds connected by a divalent chemically compatible derivative to a stable, organic, polyvalent, and polymeric member free of reactive carbon-to-carbon unsaturation and free of highly water-sensitive members. The new class of liquid polyene compositions which have a molecular weight in the range 300 to 20,000, and a viscosity in the range from essentially 0 to 20 million centipoises at 70.degree.C., may usefully form a component of a system which upon curing in the presence of a free radical generator and a polythiol, forms odorless, solid, elastomeric products. The cured products may be used as sealants, coatings, adhesives and molded articles.
