Publication number: 20090200216Abstract: A treatment station for a water drainage conduit has a chamber with an inlet and outlet in fluid communication with upstream and downstream sections of the conduit and a sediment collection portion. Water enters the chamber via the inlet, collecting in the sediment collection portion until it reaches a level in the chamber such that it flows out of the outlet. A filter is mountable above the sediment collection portion for the upwards-flowing filtration of water passing through the chamber to remove organic contaminants. Access means are provided for removal and replacement of the filter and removal of solid material deposited in the sediment collection portion. The treatment station may also have by pass means which operate where the flow of water exceeds a rate which can flow through the filter and preliminary sediment collection chamber for collecting large quantities of sediment. Uses of the treatment station are also described.Type: ApplicationFiled: April 26, 2006Publication date: August 13, 2009Applicants: Iain Aleander Stewart Robinson, The University Court of the University of EdinburgInventors: Iain Alexander Stewart Robinson, Colin John Cunningham

Publication number: 20080165916Abstract: A method and apparatus for imaging an object including the steps of projecting radiation from a radiation source through an object and moving the radiation source through multiple imaging positions relative to the object without stopping movement of the radiation source. Movement is accomplished while projecting radiation at more than one of the imagining positions with the source having a source velocity for at least one imaging position that is different from a source velocity for a second imaging position. Radiation transmitted through the object is also detected. Radiation may be projected while moving the radiation source through the multiple imaging positions. In addition, the velocity at which the radiation source is moved through a select imaging position may be related to a resolution desired for data collection at the select imaging position. The velocity of the radiation source may be varied within a select imaging position.Type: ApplicationFiled: January 5, 2007Publication date: July 10, 2008Applicant: DEXELA LIMITEDInventors: Martin Stanton, Alexander Stewart, Gordon D.

Publication number: 20080020939Abstract: The invention relates to compositions, systems, and methods for simultaneously detecting the presence and quantity of one or more different compounds in a sample using aptamer beacons. Aptamer beacons are oligonucleotides that have a binding region that can bind to a non-nucleotide target molecule, such as a protein, a steroid, or an inorganic molecule. New aptamer beacons having binding regions configured to bind to different target molecules can be used in solution-based and solid, array-based systems. The aptamer beacons can be attached to solid supports, e.g., at different predetermined points in two-dimensional arrays. The invention includes devices, methods, and computer software for carrying out the methods.Type: ApplicationFiled: December 22, 2006Publication date: January 24, 2008Inventors: Martin Stanton, Pieter Wensink, Alexander Stewart

Patent number: 6744848Abstract: The present invention provides a system for imaging an object by irradiating it with low doses of radiation, such as x-ray, from a plurality of positions angularly distributed about the object, and analyzing the intensity of the radiation transmitted through the object. A system according to the invention can include a radiation source, a low noise detector, and an image processor. The radiation source emits radiation toward a target scene, containing an object to be imaged, from a plurality of angular positions. In one embodiment, the plurality of angular positions defines an arc about the target scene. In another embodiment, the radiation source moves in a series of steps of varying angular spacing along the arc to generate the multiple images of the scene. The detector is positioned to detect radiation transmitted through the scene and produces radiation transmission data representing the intensity of the radiation transmitted through the scene.Type: GrantFiled: February 12, 2001Date of Patent: June 1, 2004Assignee: Brandeis UniversityInventors: Martin Stanton, Alexander Stewart, Walter Phillips

Patent number: 6168174Abstract: The cart is formed of a lightweight, rearwardly and upwardly inclined frame members having a support for a golf club bag such as a set of spaced tubular members, and a bottom frame. The bottom end of the inclined frame is pivotally connected to the front end of the bottom frame. A handlebar is connected to the top end of the inclined frame. At least one large wheel is rotatably attached to the front of the bottom frame and at least two wheels having at least the spacing of the front wheel and preferably a larger diameter than the front wheel are rotatably attached to the back end of the bottom frame. The cart is pushed from behind, rides very smoothly and is stable on uneven terrain and stands unassisted on its wheels when stopped. Rotatable connection of the inclined frame to the bottom frame permits the golf cart to be folded to a compact configuration which can be stored in a flat, elongated rectangular bag.Type: GrantFiled: February 5, 1999Date of Patent: January 2, 2001Inventor: Alexander Stewart MacDougall
