Abstract: This invention relates to the stoichiometric condensation of substituted phenylacetonitriles with dibasic carboxylic anhydrides. The resulting cyano-keto-acids are obtained in good yield and can be used to prepare biologically active 2-aryl-1,3-cyclohexanediones without elaborate purification.

Abstract: An improved design for a compact floppy disk cartridge is provided in which the wiping fabric is prevented from moving and causing stringers out the head access window. This is accomplished by providing ribs on both halves of the cartridge case which, together with raised peripheral edges on the case, provide an irregular shape. The wiping fabric is cut to a shape which conforms with the outline provided by the combination of ribs and peripheral edges. Thus, the wiping fabric is keyed into the space defined by the ribs and peripheral edges.Other improvements embodied in this design are: a compression return spring for a sliding shutter which is substantially completely covered by the shutter (thus preventing debris from interfering with the spring); and temporary interference fit closure of the cartridge shells to permit non-destructive testing.

Abstract: This invention relates to the stoichiometric condensation of substituted phenylacetonitriles with mono-esters of dibasic carboxylic acids. Use of the mono-ester results in substantially purer product by eliminating the bis-condensation observed with use of the diester reactant. The resulting cyano-keto-acids are obtained in good yield and can be used to prepare biologically active 2-aryl-1,3-cyclohexanediones without elaborate purification.

Abstract: Disclosed is a process for reducing the fouling in a heat exchanger in which a hydrocarbon stream is heated or cooled as it passes through the heat exchanger. From 1 to 500 parts per million of a saturated sulfoxide is added to the stream to reduce fouling.

Abstract: Disclosed is an oil-in-water micro-emulsion comprising 0.09 to 49.99 percent by mass oil, 50 to 99.9 percent by mass of water, and 0.01 to 10 mass percent of an antiwear agent.

Abstract: An electrical switch comprising a touch panel includes a flexible membrane having a series of parallel, electrically conductive strips formed thereon; and an opposed substrate layer having conductive strips thereon parallel and orthogonal to the membrane strips. A series of filament spacers, running parallel to the substrate layer strips, are positioned between the membrane and substrate layer to maintain the membrane strips and substrate strips in spaced-apart relation to each other. The filament spacers are secured to an associated boundary or frame. Finger or instrument pressure selectively applied to the membrane and directed toward the substrate, can establish contact between a chosen membrane strip and substrate strip to close the switch. The elastic deformation of the filament spacers enhances contact closure and contact life expectancy. The presence of insulative dust, which interferes with the current flow between the contacts, is eliminated.

Abstract: A wind electric system intended to provide power to a power grid, for use with a wind turbine which has no starting torque. The generator is one which can function as a motor as well. When the wind is too light to permit generation, an overriding clutch mechanically disconnects the generator shaft from the turbine shaft. The clutch has also the capability of locking the generator shaft to the turbine shaft in response to a control signal. When wind speed is great enough to permit generation and the turbine is stopped, a control signal is issued locking the generator shaft to the turbine shaft. Power from the power grid causes the generator to function as a motor and accelerate the turbine to permit it to be rotated by the wind. The clutch is then returned to overriding operation and electrical generation continues until wind speed again becomes too light.

Abstract: A novel process is provided for the preparation of carbofuran and certain intermediate products. 1,2-Cyclohexanedione is alkylated with a beta-methallyl compound and the resulting product subjected to a Claisen rearrangement/aromatization to provide the carbofuran phenol. Reaction of the phenol with methyl isocyanate converts the phenol to the desired carbofuran.

Abstract: A narrow range of dinuclear spectral sensitizing dyes can be used in photothermographic silver halide emulsions without adversely affecting fog and speed levels with concentration variations.

Abstract: In an optical recording system for both reading and writing, the laser beam is projected to the media through a diffraction grating which generates a plus one and minus one order beam ahead of and behind the main zero order beam. The grating is driven by an oscillating driver so as to wobble in a fashion which leaves the zero order beam unaffected but causes the plus one and minus one order beams to move inwardly and outwardly, radially, with respect to the information track on the media in opposite fashions. The wobbling plus one and minus one order beams are used to generate differential signals from separate detectors and are passed through a band pass filter to generate a radial position error signal which may be used to drive the write/read head inwardly or outwardly to remain positioned over a particular information track.

Abstract: A MOS power-on reset circuit includes Schmitt trigger circuit and an inverter. The Schmitt trigger circuit comprises first, second, and third depletion transistors serially connected between reference potential and supply voltage. The first and second depletion transistors are connected at a first junction point, and the second and third depletion transistors are connected at a second junction point. The gates of the first and second depletion transistors are commonly connected for receiving an input substrate bias voltage. An enhancement transistor is connected between the first junction point and supply voltage. The gates of the enhancement transistor and the third depletion transistor are commonly connected to the second junction point, which is the output of the Schmitt trigger circuit and which is coupled to the inverter from which the output voltage is taken.

Abstract: The invention relates to a method for preparing 2-lower alkyl-substituted naphthoxazoles by way of non-toxic intermediates, and in particular relates to the preparation of a 2-lower alkyl-naphtho-[2,1-d]-oxazole or a 2-lower alkyl-naphtho-[1,2-d]-oxazole, which are of industrial interest in the field of cyanine dyes for use in photography, and in the field of optical brighteners for use in plastic materials. According to the invention, an aldehyde of a lower alkyl is reacted with 2-nitroso-1-naphthol or with 1-nitroso-2-naphthol, in the presence of a strong acid and a non-aqueous organic solvent, and the condensation product is then reduced.

Abstract: The voltage output of a differential amplifier is adjusted using an active feedback loop so that there is no direct current potential difference between the differential outputs of the differential amplifier. A potential difference at the differential output of a differential amplifier due to inherent bias or operating characteristics of the system is referred to as direct current offset voltage and the need to correct this condition may be referred to as differential output direct current offset voltage compensation. The feedback loop to accomplish this compensation consists of one or more stages of isolation and amplification driven by the output voltages of the differential amplifier and having a high input impedance to diminish loading of the amplifier outputs. A voltage peak detection system is used in order to isolate direct current voltage values from alternating current voltage values appearing at the differential amplifier output.

Abstract: A microcode control memory having a first memory for receiving initial instructions is shown in combination with at least one additional memory for executing multistep control functions in a computer system. The first memory receives all initial control instructions from an instruction stack and produces the appropriate control output. Simultaneously as part of the initial instruction, a memory select network receives a control bit so that an output select network connected to the output of all memories passes the output from the first memory to the output register. Single step instructions are processed continuously this way. Multistep instructions are performed by using a portion of the output from the first memory to serve as the address selection in one of the other memories. When a multistep instruction is completed, the output select network again selects the output from the first memory for gating to the output register.

Abstract: A workpiece carrier has a support bar centrally supported at one end of a stem portion. The stem is carried at its opposite end on a base. Columns are interposed between the ends of the support bar and the base. Heat is applied to the columns, preferably by resistive heating elements, to heat them and cause their thermal expansion, causing the support bar ends to be bent away from the base. A relatively flexible workpiece which has been bonded to the support arms on a surface facing away from the base will undergo the same bend.
