Abstract: An apparatus for currency discriminating comprising first and second stationary scanheads, disposed on opposite sides of a bill transport path, for scanning respective first and second opposing surfaces of a bill traveling along the bill transport path and for producing respective output signals. The bill travels along the transport path in the direction of a predetermined dimension of the bill. A memory stores master characteristic patterns corresponding to associated predetermined surfaces of a plurality of denominations of genuine bills. Sampling circuitry samples the output signals associated with the respective first and second opposing surfaces of the scanned bill. A signal processor is programmed to determine which one of the first and second opposing surfaces corresponds to the associated predetermined surfaces of the plurality of denominations of genuine bills. The processor then correlates the output signal associated with one of the first and second opposing surfaces corresponding to the associated predetermined surfaces with the master characteristic patterns to identify the denomination of the scanned bill.

Title: Video telecommunication system and method
Inventor: AKIMOTO TAKAAKI
IPC: H04N19/89
Filed: 1997-07-04
Granted: 2000-08-29
Abstract: An image communication system and method by which an effective reference image is always stored in a (frame) memory even when the arrival of a signal at an image transmitting side from an image receiving side is delayed or an error exists in a signal reporting a reception error. In the method, the writing of encoded image data in a memory section is controlled based on the content of the signal received from the image receiving side. The control includes the judgment whether or not new data are to be written, determination of the writing position in the memory section, and erasure of already written data in the memory section. It is preferable to erase reference images older than that corresponding to the correctly received last encoded image data and the reference image corresponding to the encoded image data including a reception error reported from the image receiving side from the memory section to reduce the scale of the memory section.

Abstract: An improved ball-type check valve is provided for a reciprocating pump. The valve is an assembly having a cage containing the ball and a ball stop at the cage's fluid outlet, a ball seat and a seat retainer. A contiguous bore is formed therethrough from a fluid inlet at the retainer to the fluid outlet. The bore has an inside wall which is formed of three continuous profiles. The diameter of the bore diminishes from the fluid inlet of the seat retainer to the ball seat, then increases in the cage to the fluid outlet. Bore transitions are substantially tangential throughout. The cross--sectional area of the cage is managed to be about twice that of the ball's area. The bore of the ball seat is maximized to be within 1/8 inch of the diameter of the ball. More preferably, the ball is hollow. Accordingly, the improved valve has a low pressure drop and can operate at lower hydraulic head before vapor-locking or reduced pumping efficiency.

Abstract: Apparatus and methods are disclosed for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure. To allow the drill string to be removed from the casing, the pressure produced by the formation can be bled off and the drill string removed for servicing. The drill string can then be reinserted, the pressure in the casing above the deployment applied to preferably equalize pressure above and below the valve and the drill string run into the hole for further drilling.
