Publication number: 20220146644Abstract: A sensor comprises two independently rotatable elements. The first element comprises facets in a polygonal configuration fully rotatable about a first axis at a first angle relative to a source's beam axis and redirects energy incident on a facet at a second angle to a facet plane at a reflected angle equal in magnitude to the second angle as the first element is rotated. The second element may be a wedge mirror fully and independently rotatable about a second axis at a third angle to the beam axis that redirects energy at a fourth angle to the second axis, in a direction within the FOV, receives reflected energy to the first element for redirection toward an element interposed between it and the source that allows the source energy to pass unimpeded, and on to a detector. Correlating data from the detector and the source determines the target range.Type: ApplicationFiled: April 12, 2019Publication date: May 12, 2022Applicant: Lumibird LimitedInventors: Derek BUTLER, Philip CHURCH, Christopher GREBE, Michael SEKERKA-BAJBUS

Publication number: 20210223396Abstract: A scanning ranging sensor comprises first and second independently rotatable mirrors about respective axes. The first axis is at a first angle relative to a source's incident radiation beam axis and at a third angle relative to the second axis. The first mirror redirects the energy at a second angle to the first axis as it is rotated. The second minor further redirects the redirected energy at a fourth angle to the second axis as it is rotated, in a direction within the FOV, receives returned energy from a target and redirects it to the first minor to be further redirected toward an energy-redirecting element interposed between the source and the first mirror that allows unimpeded passage of the energy from the source, and redirects the returned energy to a detector. Correlating data from the detector with corresponding data from the source may determine the target range.Type: ApplicationFiled: May 14, 2018Publication date: July 22, 2021Applicant: Lumibird LimitedInventor: Derek BUTLER

Patent number: 7410538Abstract: A cementitious material in powder form comprising cement, also comprises sufficient of a granulated hydrophobing additive, which comprises form 5 to 15 parts by weight of an organopolysiloxane component, form 10 to 50 parts by weight of a water-soluble or water-dispersible binder and from 50 to 90 parts by weight of a carrier particle, to give from 0.01 to 5% by weight of the organosiloxane component based on the weight of the cement. The cementitious material displays good hydrophobicity, which may improve upon subsequent wettings of the applied cementitious material to a substrate.Type: GrantFiled: September 20, 2001Date of Patent: August 12, 2008Assignee: Dow Corning CorporationInventors: Derek Butler, Frederic Gubbels

Patent number: 7311770Abstract: A hydrophobic gypsum composition is provided which contains gypsum, a granulated hydrophobing additive and a pH effecting additive in an amount sufficient to maintain the pH of the composition in the range of 8 and 12.5, in the presence of water. The granule contains an organopolysiloxane having silicon bonded hydrogen, a water soluble or water dispersible binder, and a carrier, preferably gypsum or a stearate salt, in an amount sufficient to hydrophobe the gypsum. The pH effecting additive is preferably lime but may be any appropriate additive.Type: GrantFiled: September 20, 2001Date of Patent: December 25, 2007Assignee: Dow Corning CorporationInventors: James Windridge, Frederic Gubbels, Derek Butler, Manfred Wehner

Patent number: 6738024Abstract: A drive mechanism for an antenna array mounted on a moving vehicle. The antenna array is mounted on a disc having two motors which, cooperatively, rotate the disc and rotate a number of antenna elements mounted on the disc. By rotating the antenna elements, the main lobe of the array may be scanned towards a satellite in the elevation plane. To track a moving source from a moving vehicle, one of the motors rotates the disc as a whole, thereby scanning the beam in the azimuth plane. Each antenna element is at an angle to the vertical so that, by rotating the disc to face the direction of the signal source, such as a satellite, a better signal can be obtained.Type: GrantFiled: June 12, 2002Date of Patent: May 18, 2004Assignee: EMS Technologies Canada, Ltd.Inventors: Derek A. Butler, Michael R. Martin, Peter C. Strickland

Patent number: 5921231Abstract: A handheld soldering tool has a fuel reservoir or tank (10), a tip (1) heated in use by a catalyst assembly (2), a valve assembly (9) for controlling flow of gaseous fuel from the reservoir (10) to the catalyst assembly (2), and a piezo-electric ignition device (7) for igniting gas released from tank (10) for combustion during an initial warm-up period to bring the catalyst to its operating temperature. A spring member (19) mounted on a rocker member (17) serving to transmit an actuating force from a switch member (18) to the piezo device (7) is arranged to momentarily interrupt the flow of gas from valve assembly (9) through Venturi (16) to combustion region (15), to terminate the initial combustion period, during reverse movement of the rocker member (17) from an ignition disposition to a non-active or gas-flow disposition.Type: GrantFiled: January 25, 1996Date of Patent: July 13, 1999Assignee: BS Technology LimitedInventor: Derek Butler
