Abstract: A dry stain for reticulocyte staining comprising a mixture of new methylene blue N dye, potassium acetate, and an anti-blood-clotting agent. The stain is prepared in a concentrated aqueous solution, filtered, dispensed volumetrically into tubes, and dried. The correct quantity of dye per tube is determined spectrophotometrically, and the proper ratio of dye to potassium acetate is determined by pH measurements. For staining reticulocytes, whole blood is added to the tube and mixed with the dry stain. Smears are then prepared on slides in a conventional manner for microscopic examination.

Abstract: Heavy coated seeds for crops such as rice are produced by application of an oleaginous suspension of a solid, inert water-insoluble inorganic particulate material in a discontinuous oil phase dispersed in a continuous water phase. The suspension is mixed with the seeds and the coated seeds are permitted to cure during absorption of the suspension components. The suspension remaining on the seed surfaces inverts and adheres to the surfaces to increase the weight of the seeds. The suspension comprises a continuous water phase, a discontinous oil phase, and a finely ground inert inorganic particulate material.

Abstract: There are disclosed methods and compositions for the controlled release of insecticides by using a mixture consisting of (a) a hydrolyzable organic titanium compound or a partial hydrolyzate thereof, and (b) a pesticide, e.g., an insecticide.

Abstract: Pearls, corals, shells and the like are composed mainly of calcium carbonate and, therefore, they have the disadvantages that they are weak mechanically and have poor resistance to salt. In the case of using those natural products as decorative accessories such as jewelry, it is possible to prepare accessories which are less likely to crack and are more resistant to perspiration while keeping the original luster characteristic of the natural products by coating the surfaces of those accessories with fluorides in order to improve the hardness of the surfaces, and then subjecting them to further treatment with silicon compounds and non-ionic surface active agents to improve the resistance of the surfaces against acids, alkalis and salts.

Abstract: A method for repelling animals and birds consists of applying to an area being protected a composition consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic copolymer, a cross-linking agent for the carboxylated hydrophilic copolymer, a stabilizingly effective amount of an ultraviolet-absorbing agent and an animal or bird repelling compound.

Abstract: Disclosed is a low volume, space-charge controlled electrostatic spraying which is particularly suitable for use in agriculture but is applicable to industrial and other settings as well. A substance is sprayed through a relatively low voltage nozzle producing finely divided, electrostatically charged particles of the substance. The charged particles are liquid droplets or dust particles, and are about 50 microns or less in size. The space-charge density of the charged particles is monitored, and the deposition of particles on a calibration target is measured at different space-charge densities to establish an optimal space-charge density corresponding to optimum (e.g., maximum or most uniform) deposition. As the charged particles are subsequently directed to target objects, such as plants, the space-charge density is monitored and the spraying and/or charging systems are controlled to maintain the established optimal level which corresponds to optimal deposition.

Abstract: Pre-coated microscope slides are produced on a large scale by spraying a dyestuff solution on to microscope slides which are passed at a constant speed under a spray nozzle, the pattern of which is kept rectangular by means of a mask.

Abstract: A method for reducing loss of water from the leaves and stems of plants by transpiration and for protecting plants from damage by wind and cold consists of applying to the leaves and stems a transpiration-decreasing composition consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic polymer, a cross-linking agent for the carboxylated hydrophilic polymer and an effective amount of an ultravioletabsorbing agent.

Abstract: A method and composition for decreasing water resistance to movement by decreasing the surface tension and diminishing the contact angle between an object moving through water, and the water, and/or between water passing over an object and the object, thereby allowing the object to move at an increased speed with the same applied moving force or at the usual speed with less applied moving force. The method is accomplished by applying to the surface of the object which is to be moved through water a thin layer of a nonionic surface active agent which is water insoluble with the agent having a hydrophile-lipophile balance of about 7 to about 9.

Abstract: Microscope slide for blood investigation having a coating of highly purified methylene blue N and highly purified cresyl violet acetate in a weight ratio of from 1:1.5 to 1:5.

Abstract: When pullulan is used as a binder in coating seeds with inorganic materials, growth hormone preparations, etc., a satisfactory binding effect is obtained with smaller amounts than when conventional binders are used. The resulting inorganic coatings on the seeds are superior in surface hardness and disintegration characteristics in the soil after sowing. Germination of the seed and subsequent growth are not affected by pullulan. Chemically modified pullulan can also be used.

Abstract: A method of swelling the cell membranes of the cell surrounding the latex containing vessels in the underpeel of bananas to enable the latex vessels to be more resistant to temperatures within the range of 45.degree. to 55.degree. F. The method includes treating the exterior peel of the banana finger with an application of an oleaginous material having a viscosity of 10 to 10,000 centistokes, maintaining the underpeel at a temperature of above 55.degree. F during the application and holding the underpeel for a dwell period of at least 24 hours. The amount of the oleaginous material applied is sufficient to permit the oleaginous material to penetrate completely below the exterior peel and into the sites of the latex vessels' cell membranes to swell these membranes in order to prevent both a phase change in the cell membranes and an increase in the permeability of the liquid and solutes of the cells surrounding the latex vessels into the latex contained in these vessels.

Abstract: An electroless plating method for providing a thin adherent substantially continuous metallic layer over an osseous substrate such as a tooth structure. The method comprises contacting the substrate with an aqueous plating mixture containing a water-soluble salt of a metal selected from the group consisting of gold, silver, copper, nickel, platinum, palladium and tin, and a reducing agent for the metal ions of said salt. The plating mixture is maintained in contact with the substrate for a time sufficient for the metallic layer to form thereon. The metallic layer so provided is adapted for subsequent application of a tooth restorative material such as a dental amalgam for carrying out a tooth restoration.
