Patent number: 10312063Abstract: The invention relates to analyzing and controlling collection of liquid eluate output from a separation process, in particular by use of a measure of suspended material in the eluate based on a light scattering detection method. Exemplary embodiments include a method of controlling collection of a sample of a liquid eluate output from a separation process. The method includes exposing the liquid eluate to light from a light source; detecting light from the light source scattered by suspended material in the eluate at a detector; and beginning and ending collection of the sample when a measure of the suspended material derived from the detected scattered light enters and leaves a predetermined range.Type: GrantFiled: March 12, 2014Date of Patent: June 4, 2019Assignee: Malvern Panalytical LimitedInventors: Oksana Iryna Leszczyszyn, Paul G.

Patent number: 7288029Abstract: A telescoping propeller shaft includes an elongated hollow cylindrical body having a splined interior surface, the splines defining a minor diameter (x) and a major diameter (y), and a correspondingly splined shaft mating in register with the cylindrical body along an engagement length (L). Major (c) and minor (b) diameters of the splined shaft are less than the respective major (y) and minor (x) diameters of the interior splines of the cylindrical body such that the two shafts can freely telescope at least along the engagement length (L) and a free plunge region (D1). In response to a sufficient inward axial load, the cylindrical body is adapted to telescope over the splined shaft through an interference region (D2) comprising an interference mechanism for energy dissipation.Type: GrantFiled: January 19, 2005Date of Patent: October 30, 2007Assignee: GKN Driveline North America, Inc.Inventors: James Lyon, Mark Nicholls, David Sasseen
