Title: Global Control of HVAC Distribution System
Inventor: AHMED OSMAN
IPC: F24F11/04
Filed: 1995-10-03
Abstract: A global control system is implemented in a heating, ventilation and air-conditioning (HVAC) distribution system. The system allows local controllers and a source controller to exchange data between one another so that optimization of control for a local component is not sacrificed for optimization of control for a source component, and vice versa. The controllers have their control process sudivided into an identification process and a control process. The identification process periodically identifies characteristics related to the component to be controlled. The control process continuously generates a control signal to be applied to the component to control the component. The control process is further subdivided into a feedforward process and a feedback process. The feedforward process utilizes the identified characteristics to generate a control signal based on calculated system variables, while the feedback generates a control signal based on measured system variables. The two control signals are then combined to control the component. The combination of the control signals produces a more accurate control signal since the effects of noise related to the measured system variables are mitigated by the combination of control signals.

Title: Compositions and methods for increasing the immunogenicity of tumor cells
Inventor: CHEN LIEPING
IPC: A61K48/00
Filed: 1996-03-22
Abstract: The present invention is directed to a method of inhibiting tumor cell growth. Tumor cells from a patient are transfected to express both B7 and a CD2 ligand on the surface of the transfected tumor cells and these cells are then readministered to the patient. The presence of the B7 and CD2 ligand molecules on the tumor cell surface stimulates a broad immunologic response against both the transfected and non-transfected tumor cells and results in the immunologic killing of localized and metastatic tumor cells. B7 and CD2 ligand transfected tumor cells, or cell membranes, serve as an immune enhancer to engender a potent immunologic response against the surface antigens present on the tumors cells.

Title: System and method for controlling the number of units of parts in an inventory
Inventor: CAVENEY JACK E
IPC: G06Q30/02
Filed: 1996-03-22
Abstract: A computer system according to the present invention comprises in a preferred embodiment a memory, a processor, an input and an output. The computersystem receives part data and forecast data for each part in an inventory, including the number of units in the inventory, the cost, and the forecast unit demand. The computer system uses the part data and forecast data for each part to optimize the number of units of each part in the inventory for a selected inventory investment or service level constraint. The computer system optimizes the number of units of each part in the inventory by determining the number of units for each part for which the marginal increase in the number of orders for the part filled from the inventory for each additional order stocked is equal to the marginal increase for every other part and for which either the inventory service level equals the service level constraint or the inventory investment equals the inventory investment constraint. The computer system then outputs a determined minimum unit replenishment quantity and a safety unit quantity for each part. The minimum unit replenishment quantities and the safety unit quantity are used to determine the number of units of each part used to resupply the inventory.

The lock is utilized by inserting the first plate through the clearance gap between the door and its adjacent closure surface. The latch is disengaged from the drawstring so that the drawstring may be pulled to fold the webbing to move the second plate into position across the clearance gap and on the opposite side thereof from the first plate, so as to secure the door from motion with respect to the adjacent closure surface. The latch may then be engaged to hold the drawstring so as to maintain the plates in position with respect to each other.

Title: Method and mechanism for reduction of within-train reported data
Inventor: HASSAN AMER AREF
IPC: G01S15/87
Filed: 1996-05-17
Abstract: A tracking system for railcars is configured as a dynamic local area network having a master tracking unit and a plurality of slave tracking units, each tracking unit being affixed to a separate railcar. To improve reliability of communications between railcars, the distance from a master unit to a slave unit is estimated by comparing phase of a transmitted signal with that of the transmitted signal returned by another tracking unit in the network.    Optionally, a determination is made as to whether the slave unit is "ahead" of or "behind" the master unit. Communication path loss between the master and slave units due to frequency selective fading may also be determined. A spectrum survey determines quality of the channel as to its capacity for passing data from the slave unit to the master unit.

Title: Stackable Hopper Bottom for Storage Bin
Inventor: EPP RICHARD E
IPC: B65D88/30
Filed: 1996-11-04
Abstract: A hopper bottom for supporting a grain bin includes a frustro conical hopper bottom wall with a discharge opening at a central base. Around the periphery of the wall is provided a plurality of vertical legs which support the wall above a horizontal support surface. The legs are formed square tubing with a hinge part way along the leg so as to divide the leg into an upper fixed stub portion and a lower pivotal main portion. The hinge is positioned inside the inside surface of the leg so that the main portion can fold to a position extending inwardly and downwardly. The hinge includes a pair of plates welded to the upper and lower ends of the main and stub portions. The plate at the bottom of the stub portion extends outwardly from the leg with a downturn flange at its outermost end so that the upper edge of the lower hopper bottom can engage against the underside of the outwardly projecting portion allowing the hopper bottom to be stacked for transportation while the legs remain attached to the hopper bottom but folded inwardly.

Title: Laser ablation of angioplasty catheters and balloons
Inventor: FORMAN MICHAEL R
IPC: A61M29/02
Filed: 1997-01-09
Abstract: A dilatation balloon (20,98) is fabricated according to a process that yields high hoop strength and uniformity in balloon wall thickness.  A length of tubing (34) is axially elongated and radially expanded in a form (36) to provide the requisite biaxial orientation and strength.  Then, an excimer laser (46,66,84) is used to remove the polymeric material by photo-chemical ablation, virtually without thermal effects.  Dilatation balloon walls are thinned primarily along tapered sections (26,28) between proximal and distal balloon stems (30,32) and a medial working section (24) of the balloon. Material removal, particularly near the balloon stems, enables tighter wrapping of the balloon for a reduced delivery profile, and reduces rigidity near the stems for better maneuverability of the catheter in tortuous passageways.  The balloon tapered sections are reduced to a wall thickness substantially equal to that of the medial section.  Alternatively, an array of grooves (96) is formed in each tapered section.

The crossply laminates are comprised of high modulus fibers which are oriented within a range of +/- 42° to about +/- 38 ° relative to the longitudinal axis (25) of the composite spar (10). The unidirectional laminates (70) form the upper and lower sidewall regions (40, 42) and have end portions (72e) extending into the transition subregions (50). The unidirectional laminates (70) are interposed between the crossply laminates (60) and comprised of a mix of high and low modulus fibers which are oriented substantially parallel to the longitudinal axis (25). Furthermore, plies of reinforcing fabric (80) having low modulus fibers oriented above about 80° relative to the longitudinal axis (25) may be disposed between the unidirectional plies (72) of the unidirectional laminate (70). The composite spar is manufactured in molds.
