Abstract: In an electronic correcting typewriter, a character correction and replacement system is disclosed for facilitating the task of correcting typed character errors. The typewriter includes a printing and a correcting mechanism operated under electronic control and a correction buffer is associated with the electronic control for storing the last plurality of printed characters. To automatically erase any previously printed character which character has its code stored in the correction buffer and print a new replacement character, the typist locates the carrier opposite the unwanted character and actuates the character key of the desired replacement character. Under control of the electronics, the unwanted character code is recalled from the correction buffer, the correcting mechanism is operated to erase that character and the printing mechanism is operated to print the new character. Operator setting of an overstrike flag provides character overprint capability.

Abstract: Non-gelled compositions containing hydroxy ester copolymer having carboxyl groups and substantially free of oxirane groups and the method of making them are disclosed which are the esterification reaction product of(A) acidic addition copolymer; and(B) epoxy resin including aromatic polyether containing oxirane groups in which the epoxy resin comprises at least 50% of the total resin solids and contains insufficient oxirane groups to react with all of the carboxyl groups in the copolymer; in which esterification is conducted after treatment of the addition copolymer with amine in an amount sufficient to neutralize at least 5% of the carboxyl group in the copolymer. The resulting composition is neutralized with amine, is self-emulsifiable in water and is useful for coatings, e.g., for cans.

Abstract: Mechanical stability and coating characteristics of structurally cation-active, film-forming latex, especially useful in electrodeposition coatings can be improved by the addition of small stabilizing amounts of linear cationic amine-modified epoxy resin having tertiary amine functionality and base number in the range of 30-500. Such stabilized latex remain substantially non-agglomerated even after being subjected to pumping and shear. The improved latex and process circumvent the purification steps, i.e. ion exchange and also ultrafiltration, often required treatments to render latex compositions suitable for electrodeposition coatings. The thickness of the film electrodeposited on the metal can be controlled by proper selection of the stabilizer amount and/or system voltage.

Abstract: Certain alkaline earth metal salts of organic acids and diacids optionally having hydroxyl group functionality, as for example calcium and magnesium citrate, calcium dodecylbenzene sulfonate, provide improved adhesion of organic coatings electrodeposited on metal substrate. The new sanitary coatings are particularly useful for untreated aluminum and aluminum alloy cans used in the packaging of various food products including acidic foods like tomatoes, corn, and green beans which require in-can-sterilization.

F., and an approximate solid-fat index of more than about 40 at 80.degree. F. and less than about 35 at 92.degree. F.; and about 0.4-0.8% lecithin; the remainder being essentially cheese related filler; said coating having a moisture content of less than about 31/2%.

Abstract: A savory confection-like coating which has a chewy texture and a delicate flavor of a meat, vegetable, fowl or fish food group comprising a matrix-forming amount of a hard butter, a flavoring amount of a flavor of at least one of said food groups, and an inert particulate, bland carbohydrate and/or protein base material in said hard butter.

Abstract: In an electronic typewriter, an automatic word correcting system includes a keyboard word erase function key for selectively causing automatic erasure of a word or a series of words. Operation of the word correcting system is based on electronic sensing of "space" or non-print functions and successive recall of consecutively printed characters stored in a print line memory of a control circuit in the typewriter. To erase a previously typed word after other words have been typed, the operator aligns (backspaces) a carrier print point at any print line position occupied by the word. Then a single one touch (depress/release) actuation of the Word Erase Key operates an electronic word erase control that causes the carrier to automatically move to the right to find and then stop the carrier when the subsequent "space" function is electronically sensed in memory.

Abstract: A solvent-born coating composition and process for wet-on-wet application to a metal substrate comprises a fluorocarbon resin, an acrylic resin, and various flow modifiers such as benzoguanamine resins, blocked isocyanates or polymeric urethanes. Such coatings used as a primer composition in conjunction with a fluorocarbon-containing topcoat impart improved corrosion resistance, substrate and intercoat adhesion and improved edge pullaway properties.

Abstract: The invention relates to a novel fluorinated pre-polymer and novel process steps in producing the same. The pre-polymers are quinoxaline materials derived by reaction of diketone linkage containing perfluoro-compounds with an aromatic diamine. The diketone is produced by oxidatively dechlorinating a polychloroketone which may be a monoketone or a bis-ketone. The polychloroketone is produced by reacting a keto-ylid with a chlorinating agent, e.g., chlorine. The keto-ylid is produced by reacting a phosphorane with an acid halide of a polyoxy-perfluoroalkylene oxide wherein the perfluoro-oxyalkylene group contains two or three carbon atoms, and there are present from two to twenty perfluoro-oxyalkylene units in the oligomer. The quinoxalines, the polychloroketones and the diketones hereof are novel products. Cross-linking may be effected with a free radical generator.
