Publication number: 20130150813Abstract: Methods and apparatuses for detecting full waste canister and/or fluid flow path blockage conditions are disclosed. Also disclosed are methods and apparatuses for controlling a pump. In some embodiments, flow of fluid can be restricted in a portion of the fluid flow path. A controller can be configured to compare a difference in pressure values upstream and downstream of a fluid flow restrictor to a pressure difference threshold, and determine based on the comparison whether to activate an alarm indicating the full waste canister condition or the fluid flow path blockage condition. The controller can be additionally or alternatively configured to determine a fluid flow using a flow meter, open a selectable valve in response to a comparison of the fluid flow with a fluid flow threshold, determine fluid flow after opening the valve, and determine based on the fluid flow after opening the valve whether to activate the alarm.Type: ApplicationFiled: August 17, 2012Publication date: June 13, 2013Applicant: SMITH & NEPHEW PLCInventors: Benjamin Gordon, Jake Turner, Edward Hartwell, Stephen Jacob, Nathan Wrench, Edward Vernon-Harcourt, David Harris

Patent number: 8109739Abstract: A dosing pump for a liquid additive in fuel of a heavy fuel engine includes a piston, a cylinder, and a high resolution linear actuator, including a motor driven by a controller, for moving the piston axially in the cylinder. The pump includes a manifold, and a low friction dish-shaped seal having a peripheral portion forming a seal between the cylinder and the manifold in a fully extended position of the piston. The dish-shaped seal includes a top portion attached to the piston that moves with the piston such that the top portion of the seal is compressed against the manifold in the fully extended position. The shape of the seal minimizes non-linearity of the volume dosed as a function of movement of the piston, and the controller drives the motor so as to remove a remaining non-linearity of the volume dosed as a function of movement of the piston.Type: GrantFiled: September 3, 2004Date of Patent: February 7, 2012Assignee: Inergy Automotive Systems Research (Société Anonyme)Inventors: Nathan Wrench, Helen Victoria Lewis, Simon James Naylor, Charles Douglas Johnstone, James Beeching Neave
