Patent CA-2316418-A1 (CA)
Title: High speed rotor aircraft
Inventor: CARTER JAY W JR
IPC: B64C27/02
Filed: 2000-08-18
Abstract: An improved method of operating rotorcraft capable of achieving high speeds such that stability is maintained as the craft speed exceeds 0.75 times the rotor tip speed. These high speeds are achieved by varying collective pitch, including to negative values, to maintain acceptable levels of flapping at high aircraft forward speeds and low rotor rotation rates, or adjusting or maintaining the rotor rotation rate by automatically controlling the tilt of the rotor disk relative to the airstream or aircraft, or a combination of these techniques. More specifically, by utilizing these techniques the forward aircraft speeds can be high enough, and the rotor rotation rates low enough, that an advance ratio, Mu, greater than 0.75 can be achieved while maintaining rotor stability.

Title: System and method for identifying a data record associated with a transferred telephone call
Inventor: DONAGHUE NORMAN J
IPC: H04Q3/64
Filed: 1999-10-26
Abstract: A system and method for identifying a data record associated with a transferred telephone call which is not dependent on the hardware of the particular telephone network and systems involved. In the preferred embodiment, to transfer a telephone call from a first call center to a second call center, the application server of the first call center sends a transfer request which includes the data record associated with the telephone call and the destination directory number (DDN) to which the call is to be transferred by the application server of the second call center. The application server of the second call center responds by sending a transfer response which includes a Direct Inward Dialing (DID) telephone number selected from a pool of available members to be used to establish the call transfer. The application server of the second call center also stores a transfer coordination record which contains the data record, the DID number and the DDN. Upon arrival of the transferred telephone call to the second call center, the application server of the second call center uses the DID number of the transferred call to access the stored DDN number to redirect the telephone call to the intended destination in the second call center and to access the data record and re-associate the data record with the transferred telephone call. Once the transferred call and associated data record have been re-associated the DID  number is available for re-use.

Title: Circuit intended to remove currents of surface on metals and related technique
Inventor: YABLONOVITCH ELI
IPC: H01Q9/30
Filed: 1999-03-29
Abstract: A two dimensional periodic pattern of capacitive and inductive elements (12, 14) defined in the surface of a metal sheet are provided by a plurality of conductive patches (62) each connected to a conductive back plane sheet (30) between which an insulating dielectric (26) is disposed. The elements act to suppress surface currents in the surface defined by them. In particular, the array forms a ground plane mesh (24) for use in combination with an antenna. The performance of the ground plane mesh is characterized by a frequency band within which no substantial surface currents are able to propagate along the ground plane mesh. Use of such a ground plane in aircraft or other metallic vehicles thereby prevents radiation from the antenna from propagating along the metallic skin of the aircraft or vehicle. The surface also reflects electromagnetic waves without the phase shift that occurs on a normal metal surface.

Abstract: A field marker is provided for mounting on an agricultural implement for generating a marked line on the ground parallel to a direction of movement of the implement. The marker includes an arm with a marker disk at the outer end and a mounting assembly arranged such that the arm, in a working position thereof, is maintained projecting outwardly from one side of the implement and can pivot about a horizontal axis substantially parallel to the direction of movement such that the arm and ground working element can move vertically to accommodate variations in ground height. The arm can fold inwardly about a generally vertical axis to move a folded position along the side of the implement substantially parallel to said longitudinal axis. The arm is moved by a scissors lever arrangement including first and second levers and a cylinder for effecting folding of the levers about vertical axes parallel to the folding axis of the arm to a position inwardly of the arm and on top of an elongate mounting bar attached to the implement. The scissors lift provides increased stability of the arm particularly for longer arms necessary for wider implements. A spring force tending to lift the arm has a normal value for floating during operation and an increased value during folding to reduce drag as the arm folds inwardly. The spring force is provided by one spring at the arm and a supplemental spring at the scissors. The spring force is increased during folding by a second cylinder linked to the scissors cylinder with pivots an arm on the scissors to move an outer end of the supplemental spring to increase the spring force of that spring.

Abstract: A tool to remove a collar locked to the threaded shaft of a frangible fastener, having a collet with gripping means and inner grasping teeth, and having a segment removed to permit the collet to decrease in size. An outer cylinder with inner threads are sloped contrary to the threads locking the collar to the fastener shaft and a bottom inner tapered portion. An inner cylinder with matching threads and torquing means is torqued with respect to the outer cylinder to translate within the outer cylinder, urging the collet within into an inner beveled portion of the outer cylinder thereby closing the collet to surround and grasp the locked collar. While the shaft of the fastener is held, further torquing imparts rotational force to the collar in an unlocking direction.

Title: Storing and restoring snapshots of a computer process
Inventor: REUBEN DAY PAUL
IPC: G06F11/36
Filed: 2001-05-15
Abstract: A method to trace a variable or other expression through a computer program is disclosed. A user determines the variable and the conditions upon which activity of the variable will be monitored. As a result of the invention, every time that variable is referenced in a memory operation or other activity by the program and the conditions set forth by the user are satisfied, the state of that variable is saved as a snapshot without interrupting or stopping execution of the program. The snapshots are accumulated in a history table. The history table can be retrieved and the state of the variable in any given snapshot can be restored. Other variables and expressions can be attached to the trigger variable and the states of these other variables at the time of the activity of the trigger variable may also be saved in the snapshot. The method may be incorporated into a program as a tracing device or a program product separate from the logical processing device executing the program.
