Abstract: A system and a method are provided that take a potentially dangerous waste product and process the product to create a marketable asset. The system and method are configured to create “tb” from “tbgs” by removing the volatility that exists in the “tbgs.” The resultant “tb” may be substantially non-volatile.

Abstract: The invention has disclosed a system power management circuit comprising: a printed circuit board and a hardware monitor. The printed circuit board includes at least a first power connector, a second power connector, and more than one detection circuits disposed thereon; wherein the first power connector is used for electrically connecting a power supply, the second power connector is used for electrically connecting a power connector of a motherboard, inputs of the detection circuits are electrically connected to the first power connector, respectively. The hardware monitor is electrically connected to outputs of the detection circuits, and used for converting electrical signals outputted from the outputs of the detection circuits into corresponding digital signals, as well as for transmitting the digital signals to the motherboard via a two-wire bus, the two-wire bus is bi-directional, and may be an I2C or a SM bus.

Abstract: The present invention relates to injection mold hot runner control devices and more particularly to an injection molding control device which eliminates the conventional control cables to improve the quality of feedback signals received by the controller and the safety of the environment in which such systems are used. The present invention utilizes a signal processor to convert analog signals received from the mold temperature sensors into a digital feedback signal in the vicinity of the mold and to transmit such feedback signal to a receiver connected to a controller at a location remote from the mold. The mold controller processes the feedback signal and generates a corresponding control signal. The control signal is transmitted from the remotely located controller to the controlled device, typically the mold heaters.

Abstract: 1 mole of 4,4′-diphenylmethane diisocyanate is mixed with 2 moles of polyoxypropyelene glycol monoether having mean molecular weight of 2800 while adding 0.03% of tin octylate as a catalyst, and reaction is made at 80° C. for three hours for obtaining a synthetic. This synthetic is employed as a main component and blended with a filler and the like for obtaining a sealing material composite. This composite causes no swelling of a gasket forming a flange part of a trunk lid of an automobile.

Abstract: The servo amplifier is used for driving power transistors supplying current to a D.C. servo motor. The servo amplifier includes a control signal input; a tach signal input; circuitry coupled to the inputs for creating an error signal between the control signal and the tach signal; a triangular wave generator for generating a triangular wave form; a summing network for summing the error signal with the triangular wave; a modulator for modulating the resultanat signal; tri-state drive logic circuitry; and power transistor drive circuitry adapted to be coupled to the power transistors. The triangular wave modulator is coupled to the output of the summing network for supplying modulated signals to the tri-state drive logic circuitry and the drive logic circuitry having outputs coupled to the drive circuitry. The tri-state drive logic circuitry provides fast response to the error signals indicating a desired change in speed of the D.C. motor, and without over-shoot or hunting of the D.C. servo motor.

Abstract: The base drive circuit is used to drive a bipolar power switching device of the type which includes a collector, a base and an emitter (or equivalents thereto). The drive circuit includes first and second electronic switches. The first electronic switch is coupled between the collector and the base of the power switching device. The second electronic switch is coupled between the base of the power switching device and a negative voltage source which is negative with reference to the emitter voltage. The first electronic switch has a gate and the second electronic switch has a gate and both gates are connected together. A resistor is coupled between the gates of the first and second switches and a positive voltage source. A control electronic switch is connected between the gates and the negative voltage source, the electronic control switch being responsive to a control input signal.
