Title: Bottom hole assembly for cutting and pulling a tubular
Inventor: THOR-HARALD ENGEVIK
IPC: E21B34/12
Filed: 2018-11-27
Abstract: A bottom hole assembly (BHA) 10 incorporates a hydraulic jack 14 and a tubular cutter 24 driven by a downhole fluid motor 26. A valve between jack 14 and motor 26 controls whether driving fluid reaches motor 26 to drive cutter 24 or blocks fluid flow to build up pressure within jack 14. The valve is a mandrel within a surrounding housing. Ports in the mandrel selectively divert fluid to an annular fluid chamber defined by the mandrel in its housing. Relative longitudinal movement of the mandrel and housing selectively blocks the ports to operate the hydraulic telescoping jack 14 or allow diverted flow to pass into the chamber and on to operate the cutter 24 by driving the fluid motor 26. The valve can be formed as part of a scraper 28 which moves into a smaller tubular to clean an area where a spear 20 will later be engaged to elevate the tubular. After cutting, the spear 20 grabs the cut segment followed by set down weight shifting the mandrel in the scraper to buildup pressure with rig pumps to thrust the jack 14 as the BHA is held with anchors 12 in the larger tubular.

Title: Optimizing the location of an antenna system in a low latency/low data bandwidth link used in conjunction with a high latency/high bandwidth link
Inventor: Kevin J Babich
IPC: H04B10/25
Filed: 2018-10-01
Abstract: A communication system uses multiple communications links, preferably links that use different communications media. The multiple communications links may include a high latency/high bandwidth link using a fiber-optic cable configured to carry large volumes of data but having a high latency. The communications links may also include a low latency/low bandwidth link implemented using skywave propagation of radio waves and configured to carry smaller volumes of data with a lower latency across a substantial portion of the earth's surface. The low latency/low bandwidth link employs a transmitting antenna system where aspects such as antenna height, type of ground, and typography of the surrounding area at the transmitting site are adjusted to optimize the direction and angle of propagation. Controlling these and other aspects increases the predictability and reliability of the wireless link by managing the number of hops and the skip distance for each hop between the transmitting and receiving antennas. The two communications links may be used together to coordinate various activities such as the buying and selling of financial instruments.

Inventor: WENHUA XU
IPC: B33Y10/00
Filed: 2020-08-19
Abstract: A preparation method of a 4D chitosan-based thermosensitive hydrogel. Chitosan is dissolved in acetic acid solution and then printed by a 4D bioprinter into a chitosan-based thermosensitive hydrogel with a pore size of 50-100μm. This is then lyophilized after solvent extraction. Subsequently, aqueous solutions of β-sodium glycerophosphate and aqueous carboxymethyl chitosan are prepared with ultrapure water; the aqueous β-sodium glycerophosphate solution is charged into and mixed well with the aqueous carboxymethyl chitosan solution to prepare a mixture. Finally, the lyophilized chitosan is crosslinked with the mixture to obtain the 4D chitosan-based thermosensitive hydrogel. The hydrogel can be used in corneal wound healing, particularly in the repair of corneal alkali burns. In one embodiment, limbal stem cells are entrapped in the hydrogel and then applied on the surface of an alkali burned cornea such that the limbal stem cells are released to repair and treat the wound.
