Publication number: 20240083717Abstract: A zero-gravity hoist system including a chain fall, a motor coupled to the chain fall and configured to drive the chain fall in one or more directions, a power supply configured to provide power to the motor, and a controller having one or more electronic processors. The one or more electronic processors are configured to measure a first force of a load in response to receiving an input, store the measured first force in a memory of the controller, measure a second force of the load, determine a difference between the second measured force and the first measured force, and adjust a height of the load based on determining that the second force differs from the first force by a predetermined threshold.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: Matthew Post, Isabel M. Lloyd, Gareth Mueckl, John S. Scott, Matthew N. Thurin, Timothy J. Campbell, Jonathan L. Lambert, James Wekwert

Patent number: 5026890Abstract: Silicon-nitrogen compounds are prepared by the reaction of an olefinic amine such as allylamine with a polydiorganosiloxane such as 1,1,3,3-tetramethyldisiloxane, in the presence of a platinum-containing hydrosilation catalyst, preferably a specifically defined platinum complex of 1,3,5,7-tetravinyl-1,3,5,7-tetramethylcyclotetrasiloxane. Depending on the reaction conditions, the product may be any of several compounds including bis(aminoalkyl)polydiorganosiloxanes and alkenylaminodisiloxanes which are spontaneously converted to cyclic disiloxazanes. The cyclic disiloxazanes may in turn be converted by hydrolysis to bis(aminoalkyl)octaorganotetrasiloxanes.Type: GrantFiled: April 28, 1989Date of Patent: June 25, 1991Assignee: General Electric CompanyInventors: Jimmy L.

Patent number: 4976697Abstract: An obturator is provided which allows for placing and withdrawing of a single catheter obturator over an extended period of time so as to allow speed intervals of use, and non-use of a catheter while in place in the patient's skin, while at the same time doing away with cumbersome, costly and time consuming administration and maintenance of saline and heparin locks. The device feeds the obturator in place for occluding the catheter lumen, when no fluids are being administered to the patient, and then may be retracted to a position allowing fluid feed through a supply tube connection to the catheter. The device includes a coating on the obturator rod which swells in contact with aqueous fluids to seal completely the catheter lumen which coating includes heparin to prevent clotting. Moreover, the entire internal functioning arrangement remains sterile during the entire period of use, thus avoiding infection.Type: GrantFiled: October 26, 1989Date of Patent: December 11, 1990Assignee: Becton, Dickinson and CompanyInventors: Anthony J. Walder, Donald D. Solomon, Richard W. Beck, James M. Lambert, Timothy Ignatius, Mark Crawford
