Abstract: Process for making a synthetic suede product, two rolls at a time, each roll consisting of a web of fibrous material, to the upper side of which is attached outwardly extending polyurethane fibers. The process consists of continuously feeding two thin films of polyurethane into the nips formed by two rotating heated cylinders wherein the two feed materials are forced into two flexible molding bands provided with a multiplicity of molding cavities by pressing the film against a heated silicone roller. Most of the urethane film fills the cavities and forms a fibrous surface when removed, leaving a very thin layer in molten state which becomes glued to the upper layers of fibrous webs which are passed into a second set of nips formed by two rotating heated cylinders. The fibrous material or fabric may be man-made such preformed woven, knitted, foamed, non-woven, spun bonded, spun laced, etc.

Abstract: A complex alkali metal-metal-silicate material that is useful as a floc weighting agent is made by continuously bringing together concentrated solutions of alkali metal silicate and of a metal salt and substantially immediately mixing them in a vessel under high shear with a rotor.

The column may be recycled and reused.

Abstract: An additive composition containing a substantially water-soluble, alternating copolymer of maleic acid and a conjugated diene such as butadiene for reducing the drift of aqueous spray compositions. Certain salts of the copolymer may also be employed and the aqueous spray compositions may either be water or water-containing compositions containing herbicides, plant growth regulators, fungicides, insecticides, bactericides, fertilizers, defoliants, seeds, and the like as well as mixtures thereof. The drift-inhibiting additive compositions of this invention may also be used in conjunction with water-based paints. A method of dispensing aqueous compositions on the ground utilizing the drift-inhibiting additive compositions is also encompassed by the invention.

Abstract: Concentrates suitable for making fire-fighting liquids upon sixteen-fold dilution are described comprising particular perfluoro ampholytic surfactants, solvents and fluorine-free surfactants. The ampholytic surfactants are of the general formula ##STR1## wherein n represents an integer of from 1 to 20, a represents an integer of from 2 to 10, q represents an integer of from 0 to 10, p represents an integer from 0 to 10 and each of R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, are hydrogen, C.sub.1-6 alkyl orC.sub.n F.sub.2n+1 --(CH.sub.2).sub.a --SO.sub.2the solvent is a glycol or glycol ether preferably butyldigol or butyl cellosolve. When the preferred fluorine-free surfactants are used the solutions obtainable on dilution will form a film on n-hexane. The concentrates contain less than 2% of the perfluoro surfactant.

Abstract: Apparatus is described that is useful for making a stable aqueous dispersion of a complex alkali metal-aluminium-silicate which is soluble in hydrochloric acid. The apparatus comprises a mixing tube, at least two inlets through which aqueous streams can pass into one end of the tube, one of the inlets being for the supply of the bulk of the water for the process at a pressure of at least 40 psi, an outlet at the other end of the tube, and stationary means within the apparatus for causing the aqueous streams to adopt a generally helical path and to mix with one another with shear, and for causing the product leaving the outlet to be at a pressure of atmospheric pressure or less and which is at least 40 psi below the pressure in the inlet of the bulk of the water.

Abstract: Novel 1-carbamoyl-1,2,4-triazoles, processes for their production, and herbicidal compositions and methods are described. The compounds are particularly useful for the pre-weed emergence control of the graminaceous weeds crabgrass, barnyard grass, yellow foxtail and Johnson grass.

Abstract: A color correction system contains a plurality of color channels which each contain a dichroic mirror and an electro-optical modulator. An unpolarized light source shining through a color transparency serves as the input to each channel, and each color is individually controlled by the electro-optical modulator in its respective channel. The colors of each channel are then recombined after correction. In another embodiment of the invention, each channel further includes black and white film storage means to store the color image of the particular channel or inexpensive black and white film for subsequent reconstruction as a color picture.

Abstract: The end-point of an operation in which the flow properties of particulate material are altered during agitation is determined using a probe inserted into the vessel in which agitation occurs and which deflects when hit by material being agitated and detecting when the amplitude and/or frequency of the deflections of the probe changes to a given level.

Abstract: A process is described of making active dried yeast comprising drying crumbly yeast aggregates in a fluidized bed and, during the fluid bed drying, and before the yeast has a dry matter content of 80%, subjecting the aggregates to disintegration forces while they are fluidized and while the dry matter content of the yeast is from 50 to 70%, the disintegration forces being sufficient to break the aggregates down into powder but insufficient to break the yeast cells themselves.
