Title: Temporary frame identification for arq in a reservation-slotted-aloha type of protocol
Inventor: TURINA DALIBOR
IPC: H04L12/56
Filed: 1996-04-10
Abstract: Automatic repeat request (ARQ) functionality in a cellular mobile packet data communication system using a reservation slotted-ALOHA protocol is provided by assigning a temporary frame identity (TFI) to each data frame transmitted to or from a mobile station. The assigned TFI is unique among concurrent frame transfer sequences in a cell, and may be assigned based on information in a data frame sent to the mobile station or based on information in a channel reservation message that precedes the data frame sent to the mobile station. The TFI may also be assigned based on information in a channel reservation message that precedes a data frame sent from the mobile station, and the TFI assigned is unique among concurrent frame transfer sequences in a cell. The TFI is included in every block belonging to a particular frame, a block being the unit of data on which ARQ is based. A partial data frame to be retransmitted in case of a transmission error contains only the blocks determined by the ARQ protocol type (e.g., selective or Go-back-N) used, whereby a primary block need not be added to identify the mobile station. Blocks belonging to frames destined for different mobile stations can be multiplexed on the downlink based on the TFI. The mobile station may include, in its random access request, an indication that a TFI is already assigned.

Title: Diagnostic trend analysis
Inventor: LA PIERRE LEE R
IPC: G05B23/02
Filed: 1997-10-16
Abstract: A diagnostic trend analysis method (10) is used to analyze engine trend data for aircraft engines.      Appropriate trend parameters are calculated from raw trend data (12) and wild points associated with the calculated trend parameters are eliminated (14).      Abnormal shifts and changes are detected (16) at the most recent point for each trend parameter. The abnormal shifts and changes in each trend parameter are then evaluated (18). The evaluation is used to filter out spurious symptoms and provide accurate maintenance recommendations for real engine trend shifts (18).

Abstract: A process for forming sodium tungstate using a pyrometallurgical operation is provided. A tungsten containing concentrate (12) together with silica (14) and sodium silicate (16) are introduced into a slagging furnace (18). A higher density tungsten containing phase (20) settles to the bottom of the furnace crucible due to gravity and a less dense slag phase (22) segregates to the upper portion of the furnace crucible. The higher density tungsten phase (20) is introduced into a sparging furnace (24). Gas (26) from the slagging furnace (18) can be subjected to particulate control (28). The recovered particulate matter (30) can be recycled to theslagging furnace (18) and the treated gas (32) can be vented to the atmosphere. A carbon containing gas (34), such as methane, is introduced into the sparging furnace (24). The sparging step results in a crude tungsten carbide product (52) which is subjected to a water leaching step (54). The liquid portion (58) is fed to acrystallizer (60) and the crystals (64) are comminuted (66) in water (68) and subjected to acid leaching (70) with a suitable acid (72). High purity tungsten carbide (78) is then recovered.

Patent CA-2231486-A1 (CA)
Inventor: HAMPL VLADIMIR JR
IPC: D21H27/00
Filed: 1998-03-09
Abstract: The present invention is generally directed to high opacity cigarette wrapping papers. The wrapping paper made according to the present invention contains a mixture of a white pigment and a black pigment. The white pigment, which can be, for instance, calcium carbonate, has a median particle size of from about 0.1 microns to about 0.5 microns, and particularly from about 0.2 microns to about 0.4 microns. It has been discovered that this particular particle size range, which is equal to one-half the wavelength of visible light, greatly increases the opacity, brightness and whiteness of the paper. Small amounts of a black pigment, such as carbon, are then added to further increase the opacity without significantly decreasing the whiteness or brightness of the paper relative to conventional cigarette paper.

Abstract: A transmission for a four-wheel drive vehicle having a multi-speed geartrain and power transfer mechanism incorporated into a common housing assembly. The multi-speed geartrain includes a input shaft, a mainshaft, and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft to the input shaft for driven rotation at various speed ratios. The mainshaft can be selectively coupled to the power transfer mechanism for establishing two alternative power transmission routes. In particular, a synchronized range shift mechanism is provided for establishing a high-range transmission route and a low-range transmission route from the mainshaft to a primary driveline to define a two-wheel drive mode. A portion of the drive torque delivered to the primary driveline can be transferred automatically through a transfer clutch to the secondary driveline to establish an on-demand four-wheel drive mode. As an option, a mode clutch can be provided for permitting the secondary driveline to be locked to the primary driveline for establishing a part-time four-wheel drive mode.
