Patent number: 9194794Abstract: An optical absorption spectroscopy apparatus comprises a multi-pass optical cell (1) having a first reflector (2) and a second reflector (4, 4?), a first light source (6) for light of a first waveband and a second light source (6?) for light of a second waveband. The cell (1) is constructed and arranged such that light entering the cell is reflected one or more times between the first and second reflectors (2, 4, 4?) before exiting the cell. Light of the first waveband enters and exits the cell (1) in a first plane and light of the second waveband enters and exits the cell in a second plane that is different from the first plane.Type: GrantFiled: June 2, 2011Date of Patent: November 24, 2015Assignee: DUVAS TECHNOLOGIES LIMITEDInventor: Steven Wilkins

Publication number: 20130003045Abstract: An optical absorption spectroscopy apparatus comprises a light source, a detector for detecting an optical absorption spectrum of light transmitted from the source through a sample volume and one or more reflectors for reflecting the transmitted light multiple times through the sample volume. An adjuster device is provided for adjusting at least one optical element so as to vary the path length of the transmitted light by controlling the number of times the light is reflected through the sample volume. Drive means is provided for driving the adjuster device, so enabling the detector to detect the transmitted light at a range of different path lengths.Type: ApplicationFiled: February 8, 2011Publication date: January 3, 2013Inventor: Steven Wilkins

Publication number: 20060258272Abstract: A pushpin installer having a housing and a pushpin receiver having a track adapted to receive a plurality of aligned pushpins. An escapement is secured to the receiver adjacent one end of the track and this escapement is movable between a retracted position in which the escapement is laterally displaced from the track and an extended position in which the escapement extends across the track and separates two pushpins. A plunger is aligned with one pushpin after separation by the escapement so that, upon actuation, the plunger drives a pushpin from the track in a direction transverse with respect to the direction of the track and into a workpiece.Type: ApplicationFiled: August 25, 2005Publication date: November 16, 2006Inventors: Mark Milewicz, Steven Wilkins, Jeffrey Landenberger

Patent number: 6007106Abstract: A hydraulic coupling employing a polymeric elastomeric sealing member to provide an excellent seal under pressure. The polymeric elastomeric seal additionally has high resistance to acids, alkalis, hydrocarbons, ketones, ethers, esters, alcohols and salt solutions. The sealing member has the elasticity to return to its normal physical condition after pressure is removed.Type: GrantFiled: March 9, 1998Date of Patent: December 28, 1999Assignee: Snap-Tite Technologies, Inc.Inventor: Steven Wilkins

Patent number: 5730185Abstract: A pressure locking dispenser half which securely locks with a receptacle half which comprises a connector, a barrel sleeve, and a moveable adaptor. The connector includes first and second passageways. The first passageway of the connector further includes a first port and the second passageway includes a second port, a first seal and a second seal residing between the connector and the adaptor. The adaptor engages the barrel sleeve. The barrel and adaptor include a vent passageway. A spacer resides between the first and second seals maintaining separation of the first and second seals. The moveable adaptor positions the first and second seals in one of a plurality of positions with respect to the connector. A dispenser valve 12 acts in combination with a retainer, a sliding sleeve, and a locking sleeve to pressure lock the dispenser half and the receptacle half together under certain circumstances. Certain positions of the adaptor allow the venting of the dispenser half and the receptacle half.Type: GrantFiled: October 23, 1995Date of Patent: March 24, 1998Assignee: Snap-Tite, Inc.Inventors: Steven Wilkins, Wayne Wilcox, Douglas F. Hopson

Patent number: 5325890Abstract: A sanitary coupling comprising a coupler member and a nipple member. The coupler member and the nipple member have first and second passageways including first and second transverse ports and first and second longitudinal bores such that, when engaged, fluid and/or fluid and solids may flow unobstructed through the coupler and nipple members. Means for orienting the coupler member with respect to the nipple member provide alignment of said passageways of said nipple and coupler members with respect to each other for full, unobstructed flow.Type: GrantFiled: July 15, 1993Date of Patent: July 5, 1994Assignee: Snap-Tite, Inc.Inventor: Steven Wilkins
