Abstract: Improved flexibility in incorporation of soluble salts in structured aqueous liquid detergents is provided by incorporating a surfactant with a salting-­out resistance greater than or equal to 6.4 and which has an average alkyl chain length greater than 6 C-atoms provided that the liquid yields substantially no clear liquid active rich layer upon centrifuging at 750G for 20 hours at 25°C. The salting-out resistance is the minimum amount in grams equivalent of trisodium nitrilotriacetate added to 1 litre of a 5% aqueous solution of the surfactant at room temperature, to achieve phase separation as evidenced by cloudiness.

Abstract: This invention provides a thickened aqueous hard surface cleaner composition comprising colloidal alumina as the thickener in an aqueous cleaner which comprises a surfactant, electrolyte/buffer, soap and organic solvent system. These cleaner composition systems, which are the fluent, all-purpose type of cleaners, have surprising properties when thickened with the colloidal alumina. Such cleaners when thickened with colloidal alumina have a smoothly flowable or plastic consistency, and in their most preferred form, are pourable at room temperature, which consistency is not thixotropic in nature.

Abstract: Polyacrylate graft-polyols are found to be homogeneous liquids useful as dispersants in vinyl polymer polyols. The novel polyacrylate graft-polyols are made by polymerizing at least one acrylate monomer in a polyol where the resultant polyacrylate is soluble in the polyol used. The polyol may be a polyoxyalkylene polyether polyol. No copolymer or unsaturated polyol is required to make vinyl polymer polyols having high styrene/acrylonitrile ratios, good stability and improved viscosity properties when these polyacrylate graft-polyol dispersants are employed. The vinyl polymer polyols are in turn useful in reactions with polyisocyanates in the presence of suitable catalysts to make polyurethane products.

Abstract: Sugars and partly protected sugar derivatives are chlorinated by reaction of unprotected hydroxyl groups with thionyl chloride to form a persulphite followed by decomposition of the sulphite groups to form chlorosulphites, displacement of the chlorosulphite groups and insertion of chlorine atoms at one or more positions, characterised in that formation and displacement of the chlorosulphite groups and insertion of chlorine atoms is effected by reaction with thionyl chloride in an inert solvent in the presence of a quaternary salt of the general formula: 
N⁺R¹R²R³R⁴ Cl⁻      (I) 
wherein R¹, R² and R³, which may be the same or different, each represent a lower alkyl group, and R⁴ represents a hydrocarbon group with at least seven carbon atoms; and, when the sugar or partly protected sugar derivative has more than three unprotected hydroxyl groups, the process comprises the following stages:
     (a) reaction of the sugar or partly protected sugar derivative with thionyl chloride in the presence of pyridine to form a persulphite;   (b) isolation of the polysulphite to remove free pyridine; and     (c) reaction of the isolated polysulphite with thionyl chloride in an inert solvent or suspension medium in the presence of a quaternary salt of the general formula (I).

Abstract: Suspensions of programs running in a multi-programning environment are made to occur when the footprint of a program to be suspended is relatively small. This occurs when a process releases data or instruction storage in the cache because the program has moved to a different phase of behavior. An interrupt is armed to occur at small-footprint points, and then the point where that occurs is detected.

Abstract: Poly(arylene sulfide) articles having plated metal paths thereon are disclosed. A pattern of areas of lesser crystallinity and areas of higher crystallinity is created in the polymer morphology of a surface of the article. The surface is then exposed to a chemical etchant selectively active upon the areas of lesser crystallinity thereby etching those areas of lesser crystallinity while leaving areas of higher crystallinity substantially unaffected. Then a conductive metal is deposited on the etched areas of lesser crystallinity by an electroless plating process. Subsequent electroplating can also be used.

Abstract: A comparator circuit (10, 50) with hysteresis does not require any bias current as long as the input signal applied thereto is less than a lower threshold value of the comparator. The comparator includes a current source (20) for providing a plurality of currents when enabled, a Zener diode (22) coupled to the current source for initially enabling the former as the input signal exceeds an upper threshold value, an output circuit (24, 26, 28, 30, 32) which when rendered operative is placed in parallel to the Zener and disables the same while maintaining the current source enabled and providing an output signal from the comparator, and an amplifier (34, 36, 38) responsive to the current source which renders the output circuit operative as the magnitude of current sourced thereto exceeds a predetermined value. A feature of the comparator circuit is that the currents flowing in the output circuit and amplifier have complementary temperature coefficients whereby the composite temperature coefficient of the upper and lower threshold values of the comparator can be adjusted to have a substantially zero temperature coefficient.

Abstract: A remotely controlled relay having a lever (31) and a link, both of which being driven by a bistable polar electromagnet device. The lever is also manually operable. The lever drives a switch circuit to open and close while the link operates the main-circuit opening-and-closing assembly. The display (31b) provided on the lever indicates the open and closed conditions of the main circuit. A current is supplied to the coil of the bistable polar magnet device from an external circuit and magnetizes the plunger (8) such that the plunger moves through a stroke between a first and second positions. When the plunger arrives at the center of its stroke while the plunger is moving from the first position to the second position, the lever causes the micro-switch (18) to switch from the a first contact position to a second contact position. When the plunger arrives at the center of plunger stroke while the plunger is moving from the second position to the first position, the lever causes the micro-switch to switch from the second contact position to the first contact position.
