Publication number: 20230072711Abstract: Apparatus and processes for controlling a reverse osmosis system for water desalination to reduce energy consumption. The system has a controller configured to receive information from the sensor array and determine a fouling parameter for each reverse-osmosis stage based on one or more of: an A-Value, a B-value and a normalized differential pressure. The controller is then configured to control the flow through each of the reverse-osmosis assemblies based on the determined fouling parameters to meet a predetermined criterion for total permeate production for the reverse-osmosis system.Type: ApplicationFiled: June 2, 2021Publication date: March 9, 2023Applicant: SYNAUTA INC.Inventors: Michael Bruce DIXON, Cole David MACLEAN, Nicholas HEROLD, Justin QUAINTANCE

Publication number: 20180256825Abstract: The present invention safety device is a one-piece needle assembly that has a base and a housing pivotally connected to the base. The base has a distal portion to which a needle is fitted. At the base there is formed longitudinally along its distal portion a catch mechanism that may be in the form of an anchor projection. At the back wall of the housing there is extended another catch mechanism that may be configured in the form of two clasping fingers. Also providing in the housing is an integral hook. As the housing and the base are pivoted relative to each other, and as the needle makes contact with the hook, the respective catch mechanisms at the base and the housing also make contact with each other, resulting in the coupling of the catch mechanisms and the coupling of the needle to the hook. As a result, the catch mechanisms are interlocked and the needle is fixedly retained by the hook within the housing.Type: ApplicationFiled: May 16, 2018Publication date: September 13, 2018Applicant: SMITHS MEDICAL ASD, INC.Inventors: Robert Simas, JR., David MacLean

Patent number: 10046626Abstract: An apparatus for shedding material accumulated on a surface is disclosed. The apparatus is an elastic expandable vessel with fluid inlet and outlet. The elastic expandable vessel is fixed to the surface in a flat shape. Upon the introduction of fluid into the expandable vessel, the expandable vessel expands into a domed shape so that material accumulated on the surface slides off under the influence of gravity. Upon the egress of fluid out of the expandable vessel, the expandable vessel flattens.Type: GrantFiled: March 24, 2016Date of Patent: August 14, 2018Assignee: ADAGIO INDUSTRIES INC.Inventor: David A.

Patent number: 8251961Abstract: A safety needle assembly has a needle hub and a collar. Integrally formed from the proximal portion of the needle hub is a ring that surrounds its luer base. At the distal portion of the needle hub there are coaxially formed circumferential flanges which act to allow the collar to be rotatable about the needle hub. A needle protection housing is connected to the collar and is pivotable to cover the needle that extends from the distal end of the needle hub. Before use, the needle extending from the needle hub is covered by a needle sheath that has a groove formed circumferentially at its proximal end that snap-fits to a circumferential rib formed at the distal end of the collar.Type: GrantFiled: September 22, 2003Date of Patent: August 28, 2012Assignee: Smiths Medical ASD, Inc.Inventors: Marius Hauri, Frank Blinkhorn, David Maclean, Lawrence P.

Patent number: 8152761Abstract: A safety needle assembly has a collar or ring that is rotatably mounted to a needle hub, which may be connected to a medical device such as a syringe. The needle assembly may be connected to the syringe by the user grasping the needle hub in first and second embodiments, or turning of the needle sheath in other embodiments. In all of the embodiments, the collar of the needle assembly may be rotated by turning the needle sheath, which is designed to interact with the collar. In some of the embodiments, the needle hub likewise interacts with the collar in such a way that by rotating the needle sheath, the needle hub is likewise rotated for connection to a syringe. When an exposed needle is to be covered, after the needle sheath has been removed, a housing connected to the collar is pivotally moved to cover the needle.Type: GrantFiled: April 27, 2004Date of Patent: April 10, 2012Assignee: Smiths Medical ASD, Inc.Inventors: Marius Hauri, Frank Blinkhorn, David MacLean, Lawrence P.

Publication number: 20090206514Abstract: To enable a user to readily determine the gauge of the needle of a needle assembly that has a base and a needle protective housing pivotably attached thereto, the needle assembly is injection molded from a color coded molding material which color was preassigned to correspond to the gauge of the needle. As a result, both the base and the protective housing of the needle assembly are the same specific color, and reflect or provide an indication of the given gauge of the needle. The needle sheath that covers the needle prior to use may be made of a plastics material that may be clear, or have the same or a different color than that of the needle assembly.Type: ApplicationFiled: April 17, 2009Publication date: August 20, 2009Applicant: Smiths Medical ASD, Inc.Inventors: David MacLean, Frank Blinkhorn, Troy M.

Publication number: 20080045907Abstract: A safety device to be used with a vial, or capsule, has a collar dimensioned to slidably fit about the body of the vial. Extending from the collar is a neck member that has connected to its other end a housing pivotable to a position along the longitudinal axis of the vial. A latch member having a lip is integrated to the neck member and extends out from the neck member in a direction towards the center of the collar. Neck member is fabricated to have an elastic characteristic so that if it is not biased by any external force, it will return to its original position. As the collar of the safety device is moved along the body of the vial, neck member is biased away from the vial as the latch member maintains contact along the outer surface of the vial, and then the outer surface of the hub formed at the top end of the vial.Type: ApplicationFiled: October 17, 2007Publication date: February 21, 2008Applicant: Smiths Medical ASD, Inc.Inventor: David MacLean
