A method for maintaining pressure in a wellbore during drilling operations is disclosed. The method includes the steps of providing fluid from a reservoir through a drill string, circulating the fluid from the drill string to an annulus between the drill string and the wellbore, isolating pressure in the annulus, measuring pressure in the annulus, calculating a set point backpressure, applying back pressure to the annulus based on the set point back pressure, diverting fluid from the annulus to a controllable choke, controllably bleeding off pressurized fluid from the annulus, separating solids from the fluid, and directing the fluid back to the reservoir. An apparatus for maintaining pressure in a wellbore during drilling operations that includes an adjustable choke for controllably bleeding off pressurized fluid from the wellbore annulus, a backpressure pump for applying a calculated set point backpressure, and a processor for controlling the adjustable choke and backpressure pump is also disclosed.

A zipper closure for a polymeric package includes a plurality of profile members on a first polymeric surface, where one and not more than one of these plurality of profile members is colored differently from the remaining profile members on the same polymeric surface. The differently colored profile members provide a visual reference for properly orienting the zipper closure to the polymeric packaging during manufacture.

A dispenser (10) for use in dispensing liquid or solid material. The dispenser (10) includes wall portions forming a sealed first chamber (18) containing the material and wall portions forming a second chamber (20) and a molded, rupturable membrane (34) disposed between the first chamber (18) and the second chamber (20). The rupturable membrane (34) is preferably a circular disk with a series of molded radial depressions (40) or weld seams (40) extending from a center point of the disk. When pressure is applied directly to the membrane (34), the membrane (34) is fractured along the depressions (40) or weld seams (40). A method is provided for forming the dispenser (10) by injection molding.

A biometrically locked medication bottle lid including a bottle assembly, an alarm assembly and a lock assembly is disclosed herein. The bottle assembly includes a lid and a dispenser mechanism comprising a spring and a tray to dispense medicament. The alarm assembly includes a digital display that is attached to the front side of the bottle. A speaker and a light are also attached to the front side of the bottle and can be activated when an alarm is triggered indicating that it is time for a user to take their medication. The lock assembly includes a fingerprint sensor and a lock mechanism. The lock mechanism is actuated when the fingerprint sensor scans the fingerprint of the user.
摘要:
An implantable fixation device for rejoining opposed portions of a separated bone. The device including two corresponding plates that are configured to be aligned and coupled to a bone, such as a sternum, pre-resection of the bone or prior to cutting/separating the bone. The placement of the corresponding plates provides a gap between the edges of the plates that face one another allowing for and guiding a cutting tool for separating the bone. After the bone has been cut and the desired surgical procedure performed, the plates also assist in realigning and fixation of the bone portions. At least one plate includes a ratchet mechanism that is configured to tighten a locking element and draw the two plates together and into alignment with one another.
