Title: Diesel engine speed control to prevent under-run
Inventor: KRAMER THOMAS K
IPC: F02D41/12
Filed: 2001-06-01
Granted: 2006-02-07
Abstract: An engine speed governor [10] controls a diesel engine in a motor vehicle to reduce engine speed under-run after coasting. The engine control processes data for engine speed governing, including developing fuel request data comprising data components derived from proportional, integral, and derivative processing of difference between actual engine speed (N) and requested engine speed (NDES). A data source (DDS STS), such as a gear selector switch or a clutch switch, distinguishes between engagement and disengagement of the vehicle driveline from the engine. A respective first table, maps (14, 24, 34), for each of the proportional, integral, and derivative processing, provides selectable calibration values for the processor to develop the fuel request data when the driveline is engaged. A respective second table, functions (16, 26, 36), for each of the proportional, integral, and derivative processing, provides selectable calibration values for the processor to develop the fuel request data when the driveline is disengaged.

Title: Method and apparatus for separating metal values
Inventor: BIRKEN STEPHEN
IPC: C22B23/02
Filed: 2003-02-19
Granted: 2010-02-16
Abstract: Methods and apparatuses for separating metal values, such as nickel and nickel compounds, from mineral ores, including lateritic ores are disclosed. The method includes providing a mixture of particles (e.g., crushed and sized ore) that is composed of at least a first group of particles and a second group of particles. Group members have similar chemical composition, while particles belonging to different groups have dissimilar chemical compositions. The mixture of particles is exposed to microwave/millimeter wave energy in order to differentially heat the first and second group of particles, thereby increasing differences in magnetic susceptibility between the first and second gorup of particles. The mixture of particles is then passed through a magnetic field gradient, which causes the particles to separate into magnetic and non-magnetic fractions.

Granted: 2009-12-22
Abstract: A system and method for measuring fluid or gas flow rate, for the system where fluid or gas is pumped, such as gas monitoring instrument, via a conduit to a sensor. The flow of gas through a pump (14) is determined by measuring motor back emf which is proportional to motor (12) speed. The motor (12) speed is controlled by pulse width modulation "PWM" control (40) of the motor drive (38) voltage. The back emf is sampled (44) during intervals between the drive pulses applied to the motor (12). The sampling is done at selected, spaced-apart or infrequent intervals such as ones for every ten or once for every hundred motor drive pulses. In an instrument that uses a microprocessor (56) and analog-to-digital converter (50) to measure gas concentration, the same microprocessor (56) and converter (50) can provide the PWM control of the pump (14) in response to back emf generated by the pump motor between the drive pulses. The output of the analog-to-digital converter (50) that corresponding to the back emf, which in turn corresponds to the pump motor speed is compared via microprocessor (56) to set-point value of the desired pumpmotor speed. The processor then adjusts the PWM to remain the desired motor (12) speed.

Granted: 2008-11-18
Abstract: A positive pressure actuated aerator valve assembly adapted to discharge compressed gas into the chamber of a bulk material handling structure. The aerator valve assembly includes a housing and positive pressure actuated valve. The housing includes a chamber adapted to receive compressed gas and a discharge piston slideable between an extended position and a retracted position. The valve includes a valve body having an actuator piston seat and a fluid vent passageway in fluid communication with the actuator piston seat. An actuator piston is slideable with respect to the valve body between a retracted position and an extended position. A positive displacement force is applied to the actuator piston, such as by the supply of pressurized gas to the valve, to slide the actuator piston from the retracted position toward the extended position whereupon gas within the chamber of the housing flows through the fluid vent passageway and the discharge piston is moved from the extended position to the retracted position by gas within the chamber to thereby place the chamber of the housing in fluid communication with the fluid passageway of the piston seat.

Abstract: The present invention improves conventional quadribalanced displays, such as those employed in digital time displays for general purpose timekeeping. Increasing digital minutes are displayed on the right flank of centrally positioned digital present hours, in relatively upper and lower positions during the first and second quarter hours, followed by decreasing digital minutes displayed on the left flank of digital next hours, in relatively lower and upper positions during the third and fourth quarter hours. Markers are simultaneously displayed in one or more of the three quarter hour minute positions not containing digital minutes at any one time to inform the viewer that such marked positions are functional elements of the display but not activated as the current time is being displayed in another of said minute positions. A single displaceable crown control is also provided for facilitating the operation of a timepiece embodying such enhanced quadribalanced time displays and methods.
