Patent number: 11624812Abstract: A method and apparatus for quantitatively characterizing performance of a laser steering galvanometer mirror directs a laser beam from a calibration “sensor” onto a side region of the mirror to directly determine rotational positioning, velocity, and/or acceleration thereof using interferometry, time-of-flight measurements, and Doppler measurements. Measured positioning errors can be compared with a database to predict required calibration adjustments. Embodiments automatically adjust digital calibrations. Mirrors, splitters, and/or a plurality of sensors can apply measurement beams simultaneously or sequentially to both sides of a mirror, and/or to more than one mirror. Large rotation ranges, for example larger than +/?15 degrees, can be accommodated by applying measurement beams from a plurality of directions. The calibration apparatus can be distinct, or integral with the galvanometer, and can be used to monitor and/or to control the mirror positioning.Type: GrantFiled: June 13, 2018Date of Patent: April 11, 2023Inventors: James MacMillan, Leonard Williams

Patent number: 10767144Abstract: A soap reforming assembly includes a housing and a soap collection unit that is coupled to the housing for collecting and transporting pieces of soap when the pieces of soap are dropped into the housing. A heating element is coupled to the housing and the heating element heats the soap collection unit to melt the soap pieces into a fluid soap. A forming unit is positioned within the housing for receiving the fluid soap from the soap collection unit when the heating element produces the fluid soap. The forming unit cools and forms the fluid soap into a bar for bathing. A drawer is slidably positioned in the housing and the drawer receives the bar of soap from the forming unit. The drawer is positionable in an open position having the drawer extending outwardly from the housing to dispense the bar of soap.Type: GrantFiled: September 5, 2018Date of Patent: September 8, 2020Inventors: Cheryl Green, Leonard Williams

Patent number: 8910795Abstract: A magnetic separator comprising a vibratory conveyor for vibratorily flowing non-ferrous articles and articles containing ferrous material within the magnetic field of a transverse extending magnet to magnetically capture the articles containing the ferrous material while allowing the non-ferrous articles to flow therepast. The magnet is periodically retractable to remove ferrous articles magnetically adhered thereto. The use of a set of transverse extending magnets enables a continuous on-the-go separation of articles containing ferrous material from non-ferrous articles without having to shut down the vibratory conveyor.Type: GrantFiled: June 25, 2013Date of Patent: December 16, 2014Assignee: Dynamic Air Inc.Inventors: James Steele, Leonard Williams

Publication number: 20060194745Abstract: Compounds and methods are provided for modulating in vitro and in vivo processes mediated by selectin binding. More specifically, selectin modulators and their use are described, wherein the selectin modulators that modulate (e.g., inhibit or enhance) a selectin-mediated function comprise a class of compounds termed BASAs (Benzyl Amino Sulfonic Acids, which include a portion or analogue thereof linked to a carbohydrate or glycomimetic.Type: ApplicationFiled: April 26, 2006Publication date: August 31, 2006Applicant: GlycoMimetics, Inc.Inventors: John Magnani, John Patton, Leonard Williams

Publication number: 20050259255Abstract: An apparatus and method are provided for detecting presence in gas of transient particulate above its normal zero or acceptable level within a duct (4), said apparatus comprising at least one emitter (2) of illumination selected from infra-red, ultraviolet and visible radiation capable of being projected over essentially the entire cross section of the duct (4) and at least one detector (8, 18, 25) for detecting any sparkle of the illumination from the particulate. The apparatus and method are in particular useful for detecting monitoring particulate in areas where build up or presence of particulate can be disadvantageous, for example hospitals and electricity generating stations.Type: ApplicationFiled: October 4, 2004Publication date: November 24, 2005Inventors: Leonard Williams, John Bann, Nigel Harris, Jeremy Siddons

Patent number: 4976288Abstract: Tubing or pipe bend or elbow for use in carrying pneumatically conveyed granular material has an axial bore with an input opening at one end and gradually diminishes to a smaller opening at the output end, such that the incoming material sees a pressure relief, or drop, at the input to the bend. As a feature, a tubing bend may be segmented, i.e., made out of a series of separate or individual bends with the output of one coupled to the input of another.Type: GrantFiled: June 22, 1989Date of Patent: December 11, 1990Assignee: Dynamic Air, Inc.Inventors: James R.
