Granted: 1997-12-09
Abstract: An improved powertrain control which recognizes the occurrence of positive engine torque caused by accelerator walk-in by the operator during coast-sync-coast downshift, and effectively prevents or arrests speed flare via engine torque management controls.  The engine spark timing is normally not responsive to coast-sync-coast downshift conditions, however, when the occurrence of accelerator walk-in results in excessive positive engine torque likely to cause, or actually causing, engine speed flare is detected, spark retard is controlled to a predetermined value, thereby controlling the transmission input torque and allowing smooth application of the on-coming element for completion of the shift.

Abstract: A water tank is divided into a heated compartment and a cooled compartment by an insulated baffle. A perforated cylinder is mounted within the tank and has a first segment which extends within the heated tank compartment and a second segment which extends within the cooled tank compartment. Portions of a helical auger extend within each cylinder segment. Heated water is supplied to the heated compartment by a heated water manifold and cooled water is supplied to the cooled compartment by a cooled water manifold. Mixing of the heated and cooled water is prevented by the insulating baffle. Food product is caused to traverse the length of the heated compartment by the auger, and is transferred over the baffle into the cooled compartment by a lifting flight which elevates food product from the water into a chute which discharges into the cooled compartment. A single, self-contained apparatus thus blanches and cools food product in a continuous process.

Abstract: A method of using the existing radio resources to automatically determine the current cellular topology is described. Wireless base stations are placed into a mode where they can transmit a signal which can be received by all of the base stations in range of the transmitting base station. Each base station in the system serially broadcast a signal which is received by all other base stations within the range of the transmitting base station. Each of the receiving radios determines the RSSI (Received Signal Strength Indication) at which they received the transmitted signal. The RSSI values are used to determine which base stations are physically co-located into cells and then determine the relative locations of the cells to each other. A method is also described by which the wireless system monitors the mobility traffic of subscribers and makes use of this information to improve the operation of the system. As the user makes use of the mobility features of the system by making and receiving wireless calls, the mobility patterns of the users are tracked and fed into an algorithm which determines and updates to the central wireless configurations. Hence, over time the system is able to determine which cells are more likely to be involved in handover situations.

Title: Preparation of coffee products with improved particle packing characteristics
Inventor: WONG VINCENT YORK-LEUNG
IPC: A23F5/08
Filed: 1994-06-16
Granted: 1999-07-20
Abstract: Disclosed is the preparation of particulate coffee products with improved particle packing characteristics. Fine coffee particles having particle diameters of less than about 600 micrometers are compacted to a bulk density of from about 0.40 to about 0.70 gm/cc. The resulting coffee products have the isodensity and isobrew solid profiles as shown in Figures 1 and 2, respectively, where the bulk density and brew solid values for any ternary particle mixture represented on the graph increases with increased coffee fine fractions therein. The process can also be used to control or increase the bulk density of particulate coffee products thereby eliminating or reducing the need to rely upon roasting means to control bulk density. The compaction operation changes the particle morphology without rupturing the cell walls of the coffee.
