Abstract: A platen (50) for a molding machine includes an intermediate support structure (20) between two planar walls (16, 18) having ribs (40) arranged at a non-normal angle b to a first wall (18). The ribs (40) couple forces from the first wall (18) to the second wall (16) in such a way that bending of the second wall (16) is resisted. This adds to the rigidity of the second wall (16) and hence the platen (50), adding to flatness of the arrangement. Gussets (42) may be provided extending between the ribs (40) and the intermediate support structure (20). This has the effect of surrounding and supporting an injection bore (14) and further adding to the coupling of forces to the edge portions of the second wall (16) to resist forces acting to bend the wall.

Abstract: In macroblocks to which a prediction mode determination step, which determines whether or not a prediction mode applied to the macroblocks is a predetermined prediction mode, and an encoded data selection step, which selects a predetermined type of encoded data corresponding to the pixels at predetermined positions in the macroblocks to which the predetermined prediction mode is applied, are applied, there is provided a bit distribution step for more preferentially distributing bits to a predetermined type of encoded data selected at the encoded data selection step than a predetermined type of encoded data that is not selected at the encoded data selection step in the macroblocks to which the predetermined prediction mode is applied. With these steps, it is possible to provide an encoded data selection method which can limit the encoded data per one macroblock transmitted from a decoding device to a recoding device to less than a predetermined value while suppressing the lack ratio of the amount of information of the encoded data as much as possible.

IPC: E21B7/28
Filed: 2005-09-09
Granted: 2010-08-31
Abstract: An active differential pressure device (APD device) in fluid communication with a returning fluid creates a differential pressure across the device, which controls pressure below the APD Device. In embodiments, a control unit controls the APD Device to provide a selected pressure differential at a wellbore bottom, adjacent a casing shoe, in an intermediate wellbore location, or in a casing. In one arrangement, the control system is pre-set at the surface such that the APD Device provides a substantially constant pressure differential. In other arrangements, the control system adjusts an operating parameter of the APD Device to provide a desired pressure differential in response to one or more measured parameters. Devices such as an adjustable bypass can be used to control the APD Device. In other embodiments, one or more flow control devices coupled to the return fluid reduce the effective pressure differential provided by the APD Device.
