摘要： A N,N-dinitramide salt is disclosed having the formula MN(NO.sub.2).sub.2 where M is a cation selected from the class consisting of a metal ion and a nitrogen-containing ion. The dinitramide salt exhibits high temperature stability, high energy density, and an absence of smoke generating halogens, rendering it useful as an oxidizer in rocket fuels. The dinitramide salts are meltable and pumpable oxidizers which may be used in start-stop rocket engines instead of other less stable oxidizers.

摘要： An apparatus for and method of operating a thermal actuator for a micromechanical device, especially a liquid drop emitter such as an ink jet printhead, is disclosed. The disclosed thermal actuator comprises a base element and a cantilevered element including a thermo-mechanical bender portion extending from the base element to a free end tip. The thermo-mechanical bender portion includes a barrier layer constructed of a dielectric material having low thermal conductivity, a first deflector layer constructed of a first electrically resistive material having a large coefficient of thermal expansion, and a second deflector layer constructed of a second electrically resistive material having a large coefficient of thermal expansion wherein the barrier layer is bonded between the first and second deflector layers. The thermo-mechanical bender portion further has a base end and base end width, wb, adjacent the base element, and a free end and free end width, wf, adjacent the free end tip, wherein the base end width is substantially greater than the free end width. A first heater resistor is formed in the first deflector layer and adapted to apply heat energy having a first spatial thermal pattern which results in a first deflector layer base end temperature increase, &Dgr;T1b, that is greater than a first deflector layer free end temperature increase, &Dgr;T1f. A second heater resistor is formed in the second deflector layer and adapted to apply heat energy having a second spatial thermal pattern which results in a second deflector layer base end temperature increase, &Dgr;T2b that is greater than a second deflector layer free end temperature increase, &Dgr;T2f. Application of an electrical pulse to either the first or second heater resistors causes deflection of the cantilevered element, followed by restoration of the cantilevered element to an initial position as heat diffuses through the barrier layer and the cantilevered element reaches a uniform temperature. For liquid drop emitter embodiments, the thermal actuator resides in a liquid-filled chamber that includes a nozzle for ejecting liquid. Application of electrical pulses to the heater resistors is used to adjust the characteristics of liquid drop emission. The barrier layer exhibits a heat transfer time constant &tgr;B. The thermal actuator is activated by a heat pulses of duration &tgr;P wherein &tgr;P

摘要： An apparatus for and method of operating a thermal actuator for a micromechanical device, especially a liquid drop emitter such as an ink jet printhead, is disclosed. The disclosed thermal actuator comprises a base element and a cantilevered element extending a length L from a base element and normally residing at a first position before activation. The cantilevered element includes a barrier layer constructed of a dielectric material having low thermal conductivity, a first deflector layer constructed of a first electrically resistive material having a large coefficient of thermal expansion and patterned to have a first uniform resistor portion extending a length LH1 from the base element, wherein 0.3L≦LH1≦0.7L, and a second deflector layer constructed of a second electrically resistive material having a large coefficient of thermal expansion and patterned to have a second uniform resistor portion extending a length LH2 from the base element, wherein 0.3L≦LH2≦0.7L, and wherein the barrier layer is bonded between the first and second deflector layers. The thermal actuator further comprises a first pair of electrodes connected to the first uniform resistor portion and a second pair of electrodes is connected to the second uniform resistor portion for applying electrical pulses to cause resistive heating of the first or second deflector layers, resulting in thermal expansion of the first or second deflector layer relative to the other. Application of an electrical pulse to either pair of electrodes causes deflection of the cantilevered element away from its first position and, alternately, causes a positive or negative pressure in the liquid at the nozzle of a liquid drop emitter. Application of electrical pulses to the pairs of electrodes is used to adjust the characteristics of liquid drop emission. The barrier layer exhibits a heat transfer time constant &tgr;B. The thermal actuator is activated by a heat pulses of duration &tgr;P wherein &tgr;P

摘要： A process and apparatus for protecting a media bed filter with underlying support screen from solids contained in a liquid, such as filtrate from the filter, used to regenerate or backwash the media bed filter. Filtrate enters a first collection chamber containing a screen assembly covering one outlet, the chamber also containing a second outlet. Filtrate traverses the screen assembly and is transferred to a second collection chamber with addition of a predetermined amount of bactericide to prevent solids growth therein. Upon bactericide-treated filtrate reaching a predetermined level within the second chamber, filtrate in the first chamber bypasses the screen assembly and flows out the second output to further biological treatment or use. Bactericide-treated filtrate from the second collection chamber is used to regenerate or backwash the media bed filter with addition of optional surfactant to assist in cleaning the filter media and underlying support screen. The first collection chamber has an alarm system which detects resistance of filtrate flow traversing the screen assembly and warns that the screen assembly requires cleaning or replacement, thus fully protecting the support screen from solids.

摘要： This invention pertains to a process for extracting a nitroaromatic composition from a nitration medium containing nitric acid, water, and nitroaromatic. The process comprises contacting the nitration medium with nitric oxide under conditions such that the nitric oxide will react with the nitric acid to form nitrogen dioxide and water. Gaseous nitrogen dioxide is removed from the reaction medium and accordingly, the dissolved nitroaromatic present in the nitration medium separates to form an organic phase which then can be removed by decantation. Typically, one mole of nitric oxide is added to the nitration medium for every two moles of nitric acid present in said medium. Reaction conditions normally are from about 0.degree. to 90.degree. C.
