Abstract: A process for continuously controlling the transfer of torque within a differential where a target delta (.DELTA.T) value is determined as a function of a first differential output shaft speed (.omega.a) and a second differential output shaft speed (.omega.b) and then normalized according to the vehicle speed when the vehicle is being driven under a no wheel slip condition. A normalized actual delta (.DELTA.A) is also determined as a function of the first output shaft speed (.omega.a) and the second output shaft speed (.omega.b), a comparison is made between .DELTA.T and .DELTA.A and torque is transferred between the first and second output shafts of the differential according to a logic control methodology such as proportional, integral, and/or derivative (PID) control methodologies if the comparison result of .DELTA.A to .DELTA.T is outside of a tolerance range established around .DELTA.T.

Abstract: A calcining system (10) is operated in a substoichiometric mode for reducing nitrogen oxide generation and removing sulfur from materials (26) to be processed by creating an oxygen deficient atmosphere. The calcining system (10) includes a rotary kiln (14) rotating on a slightly inclined horizontal axis. The rotary kiln (14) has a feed end (22) introducing material (26) to be processed and a discharge end (24). A preheating/precalcining device (12) is positioned adjacent the feed end (22) such that the material (26) passes through the device (12) prior to entering the rotary kiln (14). A stationary hood (16) surrounds the discharge end (24). A burner (18) is supported by th e stationary hood (16). The burner (18) introduces combustible fuel (38) and combustion air (40) into the rotary kiln (14) through the discharge end (24) and operates in a substoichiometric mode. At least on air nozzle (44) is located along the length of the rotary kiln (14). The air nozzle (44) inject s combustion air (40) into the rotary kiln (14). The combustion air (40C) introduced by the air nozzle (44) completely combusts the combustible fuel (38) introduced by the burner (18) before the combustible fuel (38) exits th e feed end (24).

Abstract: In a shift mechanism for an outboard motor mounted on a stern of a boat and having an internal combustion engine and a propeller connected by a propeller shaft to the engine to propel the boat, a vertical shaft connected to the engine and transmitting an output of the engine to the propeller shaft is divided into two shaft halves and an electromagnetic clutch is provided to connect/disconnect the shaft halves. An electronic controller is provided to operate the electromagnetic clutch to disconnect the vertical shaft halves until one of the forward and reverse gears corresponding to the instruction to shift has been engaged with the propeller shaft, and then operate it to connect the shaft halves after the one of the forward gear and the reverse gear has been engaged with the propeller shaft. Alternatively, two electromagnetic clutches are provided to engage the forward or reverse gear with the propeller shaft, and the controller controls operation of the electromagnetic clutches in response to the instruction to shift such that corresponding one of the forward and reverse gears is engaged with the propeller shaft. With this, it becomes possible to decrease an impact occurring at the beginning of shift, thereby enabling to prevent the outboard motor from vibrating, while enabling to improve the operation feeling and facilitate maintenance, and to avoid a problem regarding space utilization.

Granted: 2011-12-13
Abstract: The invention relates to a safety system for a lift installation (10) for the transport of persons/goods in a building (30) and to a method for operating a lift installation (10) with a safety system. Several cages (2, 2') are moved one above the other in a shaft (31). Each cage (2, 2') is moved by a drive (6, 6'). At least one drive control (16, 16') controls the drives (6, 6') by way of drive control signals. Cage position detecting sensors (21, 21') detect positions of each cage (2, 2') and transmit cage position data to at least one safety control (26, 26'). Access to the shaft (31) takes place by way of opened shaft doors (11.0 to 11.8). A lock (18.0 to 18.8) locks shaft doors (11.0 to 11.8). Lock setting detecting sensors (20.0 to 20.8) detect settings of the locks (18.0 to 18.8) of the shaft doors (11.0 to 11.8) and transmit lock setting data by way of the data bus (22) to the safety control (26, 26'). The safety control (26, 26') ascertains, from the cage position data and the lock setting data, shaft region data with details with respect to shaft regions in which each cage (2, 2') is safely movable. The safety control (26, 26') transmits the shaft region data to the drive control (16, 16'), which converts the shaft region data into drive control signals in order to move the cages (2, 2') in separate shaft region s and in order to move the cages (2, 2') in shaft regions with locked shaft doors (20.0 to 20.8).

Granted: 2012-03-13
Abstract: A system and method is disclosed for determining the location of a mobile appliance using the reverse pilot channel provided in CDMA200 communication systems to determine an attribute of a reverse pilot signal at one or more wireless location sensors (Fig.4). A network overlay of wireless location sensors monitors the reverse pilot channel for a target mobile's reverse pilot signal. The monitored signal may be compared to a reference signal to determine a correlation and thereby determine an attribute of the target mobile's reverse pilot signal (Fig.6). The method may be performed independently from the communication system and without requiring retrieval of information bits from the mobile appliance. The reference signal may be generated from the unique long spreading code mask of the target mobile appliance, which is typically a function of the ESN of the target mobile appliance.
