Abstract: Aminoanthraquinones are generally useful as dyes and coloring agents. But known methods of synthesizing unsymmetrically substituted 1,4-diaminoanthraquinones are tedious and complex. A simple and efficient method is provided for preparing 1,4-diaminoanthraquinones, particularly unsymmetrically substituted 1,4-diaminoanthraquinones, by means of novel monoamino-monotosyloxy-anthraquinones.

Abstract: A torch tip for burning an oxidizer/fuel combustible mixture includes a head having multiple burners so as to produce a plurality of flames. The torch tip includes a venturi acting as a jet pump using fuel metered through an orifice to draw an oxidizer in the form of air entering from cross passages into the venturi and then into a mixing chamber in the torch tip. The combustible mixture then exits into the burners through flameholders which impart a swirling motion to the combustible mixture so that more complete combustion and a higher temperature is achieved. Each flameholder also includes a bluff body portion thereon for causing eddying of the combustible mixture in the burners, thereby further enhancing flameholding and completeness of combustion.

Abstract: Protection of the thin gate oxide of MOS field effect transistors from irreversible puncture due to undesired high voltages and currents, generated by electrostatic discharge through handling or otherwise, is provided by a two stage circuit that operates to shunt thousands or tens of volts around the protected transistors. A first stage, employing a thick field effect transistor, protects against the very high voltage. A second stage, employing a thin field effect transistor, protects against lower but still excessive voltage. The protection circuit is formed as part of an integrated circuit chip by surrounding the lead bonding pad to which the protected transistors are connected.

Abstract: Novel sulfonated phenyl esters of dicarboxylic acids are useful as diperoxyacid precursors in bleaching and laundering applications when combined with a source of peroxide. These diperoxyacid precursors can be produced by reacting a dicarboxylic acid, a phenol sulfonate, and a lower alkyl acid anhydride in an alkyl hydrocarbon solvent and removing a carboxylic acid byproduct through distillation. The diperoxyacid precursors have the structure: ##STR1## wherein n is an integer from about 4 to about 18 and M is an alkali metal, an alkaline earth metal, or ammonium. The diperoxyacid precursors have a high perhydrolysis profile coupled with a relatively low-to-moderate hydrolysis profile.

Abstract: Circuits for modifying the dynamic range of signals, particularly compressors and expanders for use in noise reduction compander systems, in which the plurality of characteristics are superposed such that as dominant signal components appear, hidden characteristics are revealed and become active. The emergence of characteristics can also be described as "action substitution" in the sense that the action resulting from one, or perhaps more than one characteristic is substituted for one or more other characteristic actions that have the potential to operate in the same frequency and level regions when the level and spectral content of the input signal components change. One particularly useful combination of superposed characteristics is a fixed band characteristic (variable attenuation throughout all or part of the frequency band) and a sliding band characteristic (variable attenuation through part of the frequency band achieved by a variable pass filter).

Abstract: In a grip-less water mixer unit, the quantity of water outflow and the mixing temperature are controlled by pivot-mounting the water outlet about two independent axes in a valve body. The water outlet is coupled to two regulating elements of which, one serves to regulate the water quantity and the other the adjustment of the mixing temperature. In a first embodiment example both regulating elements are formed as cylindrical bodies rotatable in the valve body, and in a second embodiment example, both regulating elements are concentrated in a ball which is rotatable in the valve body.

Abstract: Delayed-release hypohalite bleach compositions are provided which include encapsulates having a granular, hypohalite-releasing core and a coating delaying release of hypohalite ion and scavenging hypohalite ion when the encapsulates are exposed to an aqueous solution. The coating must include an amine compound with limited solubility in water. The core preferably includes a dihalodialkyl hydantoin and the coating an amine having a saturated hydrocarbon carbon of about 6 to about 24 carbon atoms.

Abstract: A guitar-like electronic musical instrument for use with a synthesizer has six pitch strings on the neck which the player depresses onto conductive frets to determine the selected semitone. A transducer senses if the player forces the string laterally on the fret and if the string is so laterally forced (bent) beyond a threshold, further pitch detection is inhibited. The fret construction can be much simplified and there is no danger of spurious notes being caused by contact with adjacent strings.
