Title: Encapsulation of hazardous waste materials
Inventor: RECHICHI DINO
IPC: G21F9/16
Filed: 1998-05-29
Granted: 2008-02-05
Abstract: A method of encapsulating hazardous waste materials including heavy metals such as arsenic, mercury, nickel and chromium residues, as well as radioactive materials. The method involves adding the hazardous waste material to a settable composition, forming a slurry, and allowing the slurry to set to encapsulate the waste material. The settable composition is a powdered flowable cement composition containing calcium carbonate and a caustic magnesium oxide.    Tests conducted on the encapsulated material indicate that virtually none of the hazardous waste material is leached out of the set composition which has a concrete-like appearance.

Title: Signal processing
Inventor: HOLLIER MICHAEL PETER
IPC: G10L25/69
Filed: 1998-10-09
Granted: 2006-10-03
Abstract: Communications equipment is tested for perceptually relevant distortions introduced by the equipment by generating indications (16, 29) of the extent to which such distortion would be perceptible to a human observer, and processing high-level application data (51, 61) received with the input stimulus and/or generated locally (52, 62) relating to the intended content of the input stimulus. This allows the perceptual relevance of different distortion types to be weighted in the fin al output from the perceptual layer (40) according to the nature of the signal being transmitted. The high-level information (51, 52, 61, 62) may be of a general nature, defining the type of information content in the input signal (11, 21) (e.g. music or speech) or may be highly defined, e.g. the input signal (61) accompanying a video input (21) specifying which of a limited set of objects in a virtual world i s to be depicted, such that a reference copy of said image, or characteristic features of such objects can be retrieved from a store (62). The high-level application data may be used for other purposes, e.g. to select a coding process suitable for the nature of the information content.

Abstract: A mixing system utilizes up pumping axial flow impellers (14, 16, 18) which entrain gas into the liquid both at the surface (12) and below the surface by induction to draw gas down below the surface where it is dispersed into the circulation produced by the impellers (14, 16, 18). Tubes (48) are disposed on the suction sides of the impeller blades (14, 16, 18), and provide gas outlets near the tips (50) of the blades (14, 16, 18).  The tubes (48) may extend along the shaft above the surface or into a hollow shaft having a breathing opening (46) above the surface (12). The rotation of the impellers (14, 16, 18) produces a suction at the tube outlets to draw gas into the liquid while the upward circulation produces surface turbulence for gas entrainment.

Abstract: A liquid sample analyzer with a flow-through liquid waveguide cell is described. The light source is fiber coupled to a liquid waveguide or light pipe. The light pipe can be remotely located and fiber coupled to the spectrometer so that the light source is thermally isolated making the spectrometer easily thermally stabilized, and the dispersion minimized. The liquid waveguide cell includes a light pipe that has a lower index of refraction than the liquid flowing through the light pipe. Light is input into the liquid waveguide by an optical fiber that is coupled to the liquid waveguide. The optical fiber diameter and the light pipe core diameter and spaceing are selected to provide coupling of all light modes transmitted through the optical fiber into the light pipe. The output light is received by an optical fiber which is arranged to receive all of the light transmitted through the light pipe. The light output from the light pipe is fiber-coupled to the spectrometer with a fiber bundle that is arranged in the form of a slit at the distal end or entrance aperture of the spectrometer.

Abstract: A container pick and return system is provided having a two-tiered flow rail conveyor system that includes an inclined upper set of feed flow rails forming an input conveyor assembly and a lower set of inclined return flow rails forming an exit conveyor upon which a unit load may roll. At the front end of the system is a transfer conveyor assembly that receives a loaded container. The line worker may then operate a damper control pedal that permits the container to be positioned at any desired angle greater than the angle of the input conveyor. This permits enhanced accessibility of the contents of the container regardless of the height or arm length of the line worker or the size and shape of the container contents. When the container is emptied by the line worker, the transfer conveyor assembly is triggered and the empty container is automatically lowered and transferred to the exit conveyor where it rolls down the exit conveyor to the rear of the system for reloading. Upon transfer of the empty container, the transfer conveyor assembly automatically returns to an upper position for receipt of another loaded container and subsequent angular presentation of the contents of the container.
