Title: Method and apparatus for a coriolis flowmeter having its flow calibration factor independent of material density
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/84
Filed: 1999-05-28
Granted: 2003-10-21
Abstract: A single tube Coriolis flowmeter of enhanced flow sensitivity in which material flow induces Coriolis deflections in a flow tube and Coriolis-like deflections in a balance bar vibrationally coupled to the flow tube. Both th e Coriolis deflections and the Coriolis-like deflections have a phase shift determined by material flow and are used co-adjuvantly to derive material fl ow information. The flowmeter achieves a constant flow sensitivity over a range of changes in material density by 1) varying the flow sensitivity in a first direction under control of the ratio between the drive mode vibration amplitude of the flow tube and the balance bar and 2) varying the flow sensitivity in an opposite direction under control of the ratio between the Coriolis deflection amplitude of the flow tube and the Coriolis-like deflection of the balance bar. The drive mode vibration amplitude ratio vari es with changes in drive mode frequency caused by changes in material density. The amplitude ratio of the Coriolis deflection and the Coriolis-like deflection changes with changes in the magnitude of the separation of the drive mode frequency and the second bending mode frequency to the balance ba r density which, in turn, is caused by changes in material density.

Abstract: A board trimmer having pre-trimmer saws includes a selectively translatable upstream first pre-trimmer saw mounted on a near-side of a board flow path of a board transfer, upstream of a downstream multi-saw board trimmer. The pre-trimmer saw is selectively translatable by an actuator for translation linearly parallel to a near-side ended board on the board transfer. The pre-trimmer saw is perpendicular to the board when on the board transfer. A board elevator may be mounted below the board flow path and the pre--trimmer saw for elevating the board from a sequence of single boards from the board transfer into sawing engagement with the pre-trimmer saw once the pre-trimmer saw has been pre--positioned by the actuator into an optimized cutting path. Trimming of the board in the flow path is done according to an optimized solution for trimming the board. The board may be optimally trimmed by a combination of trimming a first waste portion from a near-end of the board by the first pre-trimmer saw and by trimming a second waste portion from either or both of the near-end and a far end of the board by the downstream multi-saw trimmer.

Abstract: The present invention is a novel method and apparatus for efficiently transporting and synchronizing data between the Media Access Control (MAC) and physical communication protocol layers in a wireless communication system. Depending on the length of the MAC packet to be transported, the present invention either fragments or concatenates the MAC packet when mapping to the physical layer. When a MAC packet is too long to fit in one TC/PHY packet, the MAC packet is fragmented and the resultant multiple TC/PHY packets are preferably transmitted back-to-back within the same TDD frame. When a MAC packet is shorter than a TC/PHY packet, the next MAC packet is concatenated with the current MAC packet into a single TC/PHY packet unless an exception applies (e.g., a change in CPE on the uplink or a change in modulation on the downlink). When an exception applies, the next MAC packet is started on a new TC/PHY packet following either a CTG or MTG.

Abstract: A method for mounting a wick within a wick sustainer is disclosed. The sustainer has a base, a barrel and a passage that extends through the sustainer. The passage has an upper region occupied by the wick and a lower region occupied, at least partially, by the sealant. Sealing the lower region of the passage is accomplished by injecting the sealant into the passage, thereby preventing the fuel from contacting the portion of the wick that is retained in the upper region of the passage. Fuel reaches the flame of the burning wick only through the portion of wick not held in the sustainer, so the flame is extinguished once the fuel descends below the top of the sustainer.
