Abstract: A diagnostic system for electric motors, such as those used in automotive applications. The system comprises a controller for supplying a desired command current to said electric motor, a sensor for measuring the rotational speed of the motor, a sensor for measuring the actual current supplied to the motor by the controller, a diagnostic control unit adapted to receive the measured rotational speed, measured supplied voltage, and a command current level value as inputs. The diagnostic control unit further comprises circuitry to calculate an estimated actual current drawn by the motor and to signal an error condition if the estimated actual current is not within a calculated valid range.

Abstract: A pulsed measurement technique for calorimetric sensors provides a short current pulse through catalyzed and inert sensor elements to minimize self heating while providing for sensor resistance measurement, so that a determination of the level of catalytic activity at the surface of the catalyzed element may be made for sensing the concentration of combustible elements of automotive internal combustion engine exhaust gas. Exhaust gas temperature measurement is provided by monitoring the inert element resistance. Exhaust gas flow rate measurement is provided by heating the inert element for a short heating period, and then removing the heat source while monitoring the time rate of return to the known initial inert element temperature.

Abstract: The present invention relates to a novel nut paste having a particular monomodal particle size distribution and to monomodal full-fat nut butters and monomodal reduced fat nut spreads which contain the novel nut paste and which, as a result, have superior fluidity, texture and flavor. These nut butters and nut spreads typically comprise from about 50% to 100% of a nut paste. The Casson plastic viscosity of the nut paste is less than about 15 poise and the fat content of the nut paste is at least about 45%. The nut butters have a fat content ranging from about 25% to about 80%. The final nut butters and nut spread products of the present invention have a Casson plastic viscosity of less than about 17 poise and a yield value below about 300 dynes per square centimeter.

Abstract: A concealed fixing device comprises an insert embedded within a first member, an elongate threaded bar connected to the first member and passing through a second member through a concealed hole to a concealed chamber within the second member. A combined nut and washer assembly applied to the threaded bar tightens the first and second members.

Abstract: A novel class of 2-(1(2H)-phthalazinone)sulfenamides is described which sulfenamides are useful as inhibitors of premature vulcanization of rubber.
