IPC: E01C23/09
Filed: 2001-10-15
Abstract: A machine is disclosed, for cutting pavement such as a sidewalk, a side edge, of a bridge, a curb of an highway or the like. This machine has a powered truck-like vehicle having a support base, and a cutting apparatus mounted on the base. The cutting apparatus has two spaced-apart cylindrical booms where each boom has one end pivotally mounted on the base and an opposite end. Each boom may tilt about its one end in a vertical plane. A supporting bar is mounted on the opposite ends of the cylindrical booms so as to be free to rotate about the cylindrical booms within a plane perpendicular to the cylindrical booms. The supporting bar is provided with two extendible, ground-contacting legs at each opposite end thereof for stabilizing the apparatus. A rail- structure-holding head is slidably mounted on each cylindrical boom so as to slide along the cylindrical boom and to be free to rotate about the cylindrical boom within a plane perpendicular to the cylindrical boom. The machine further has an elongated main rail mounted on the heads so as to rotate about a longitudinal axis parallel to the elongated main rail. A saw carrier is mounted on the main rail and may moved along the main rail in a first direction parallel to the longitudinal axis. A motorized saw is mounted on the saw carrier and may move on the saw carrier in a second direction perpendicular to said longitudinal axis.

Title: System and method for treatment of water
Inventor: MIYAMOTO HENRY KORO
IPC: C02F1/461
Filed: 2001-10-23
Abstract: A system and method for treating water is disclosed.      Accordingly, the system and method treats water to remove suspended solids, as well as protozoancysts, in particular Giardia cysts and Cryptosporidium oocyst, disinfect for bacteria and viruses and remove colour, taste and odour to produce a potable water. A bacteriacide is introduced which is relatively stable and long term. Removal of such bacteriacide is also described where required for human health. The system and method introduces a bacteriacide to the water in an amount sufficient to kill the bacteria and inactivate viruses. The bacteriacide is maintained in the water at least for a time period sufficient to kill the bacteria in the water, and, until the water is desired to be consumed. In this way, there is a decreased likelihood that the water will become recontaminated with the same bacteria and/or viruses before the water is desired to be used.      Furthermore, should any bacteria not be initially killed by the bacteriacide, the presence of the bacteriacide should at least decrease the ability of the bacteria to reproduce in substantial quantities until the water is desired to be used.      In one embodiment, the bacteriacide comprises metal ions, such as silver ions and/or copper and zinc ions. When the water is desired to be used, the metal ions are removed from the water by passing the water through an ion exchange. In order to introduce the metal ions into the water, the system preferably comprises an electrode having about 70 percent to 90 percent copper, about 5 percent to 15 percent silver and about 5 percent to 15 percent zinc. Alternatively, if only silver is required, the system utilizes a silver containing electrode having an electrically conductive and structurally secure core, such as a core made from mild steel, coated with substantially pure silver. Prior to the introduction of the bacteriacide, the water may be treated by passing the water through diatomaceous earth to remove contaminants from the water and/or passing the water through an initial disinfection stage.

Title: Method for desulphurization of gases
Inventor: JANSSEN ALBERT JOSEPH HENDRIK
IPC: B01D53/52
Filed: 2000-03-08
Abstract: The present invention relates to a method of removing hydrogen sulphide from a gas stream wherein the hydrogen sulphide is scrubbed from the gas phase by means of an aqueous solution, the hydrogen sulphide in the aqueous solution is biologically oxidized in a bioreactor to produce elemental sulphur, and the elemental sulphur is separated from the aqueous solution, characterized in that the gas stream to be treated is cooled to such a degree that at least sufficient water vapour condenses from said gas stream to compensate for the discharge stream for the purpose of removing salts. This means that no water need be supplied to the bioreactor. This method is suitable, in particular, for gas streams which contain hydrogen sulphide, the hydrogen sulphide having been obtained by catalytic conversion of sulphur compounds.

Filed: 2000-08-03
Abstract: An edible product such as a unit dosage form of a pharmaceutically active substance includes a layer of a material that can receive and retain a high resolution microrelief that can convey information. The mcirorelief is thermo-formable, preferably formed from an aqueous solution of HPMC and/or HPC plus a plasticizer and colorant. Other additives such as strengtheners, surfactants and adherents may be used depending on the application. The materials are selected and proportioned to control the fading or change in color of the visual image or effect produced by the relief to indicate exposure to an unacceptable degree of heat or humidity. The dosage form can be the relief-containing layer itself with the pharmaceutical carried therein. In a preferred form, the layer is an outer coating over a core containing the pharmaceutically active substance. Coated tablets are configured to resist twinning. To produce such dosage forms, the coated core is transported in unison with a flexible mold or transfer plate that can heat-replicate the microrelief on the outer layer of the dosage form, followed by a cooling and release of the transfer plate from the coating.

Abstract: A 3D navigation system employs a complementary pair of emitter/detector units, one (10) worn on a part of a user's body (e.g., the head) and the other (20) mounted in a stationary position on a display monitor facing the user. Each unit has an array of photovoltaic (PV) cells (10b, 20b) centered on a normal axis and an infrared diode (10a, 20a) for emitting a light beam on the normal axis. Each photodetectors array receives the infrared beam from the other unit and provides output signals representing the light intensities of the received beam on the PV cells. The PV cell response signals of the complementary units are used together to calculate the position and angular orientation of the user-worn unit relative to the stationary unit. The position and angle values are used by a software device driver installed on a computer to control 3D  navigation functions of the associated application program on the computer. The system can be used for playing interactive 3D games, and also used for hands-free control in a wide range of other applications and environments, such as to control flight motions in a simulator or cockpit of an aircraft, or the command center of a naval vessel, spaceship, land vehicle, etc. for disabled persons to provide hands-free input to a computer, monorized wheelchair, prosthetic device etc, and for controlling various functions in an industrial environment, such as guiding machine-assisted movement, or in CAD design, architectural, medical graphics, virtual reality, and other applications.
