  • Patent number: 6938497
    Abstract: An acoustic flow meter in the form of a valve key has an acoustic sensor 12 for measuring the peak sound level which occurs when the key is used to close a valve in a fluid pipeline. The peak sound level can be used to accurately calculate the flow through the valve and provide the flow information on a display unit 11. Parameters for the upstream supply pressure, pipe diameter and valve characteristics can be entered to ensure the accuracy of the flow calculations. The key therefore provides a way of determining fluid flow in a pipeline to a reasonable level of accuracy without having to install in-line flow meters.

  • Patent number: 6923006
    Abstract: Water supplied from a bottle 1 is pre-chilled in a reservoir 3. A two-part water pump 11 transfers water under pressure through a jet nozzle 14 into an oxygen space 17 in a PET pressure vessel 12, which entrains oxygen into the water. The pressure vessel is received in a conductive holder 18 and is cooled by a peltier element 19 provided with cooling fins 20. The holder 18 forms a capacitive level sensor with a probe 32 inside the vessel, which starts the pump 11 when oxygenated water is drawn off via a draw tube 28 and discharge valve 31. When the water level in the oxygenating vessel is restored a solenoid valve 25 opens to restore the oxygen pressure in the vessel. For hygiene purposes the pumping body can be removed from the pump motor and replaced together with the reservoir 3 and oxygenating vessel 12 along with the associated tubing.

  • Patent number: 6921506
    Abstract: A pressed thermal insulation body is made by a method comprising the steps of: (1) providing a dry composition consisting of: (a) 10 to 100 percent by weight of volatilised silica containing a dispersion of 0.5 to 6 percent by weight of carbon; (b) 0 to 40 percent by weight of infra-red opacifier; (c) 0 to 50 percent by weight of particulate inorganic filler material; and (d) 0 to 25 percent by weight of reinforcing filaments; (2) pressing the dry composition from step (1) to form a body of a desired shape and density; and (3) heat treating the pressed body at a temperature in the range from 400 degrees Celsius to 1000 degrees Celsius to effect hardening.

  • Patent number: 6910696
    Abstract: A transporter which can be used as an infant car seat or carrier has a body shell with a curved lower surface for use as a rocker and wheels which can be extended for use as a stroller. The wheels are carried on legs which can be retracted into opposed side cheeks by means of respective drive belts. A handle 25 is secured to inner members 55 to slide within tubular arms 23 which are pivotally secured to the side cheeks. The inner members are connected by pivotal links to the respective drive belts so that extending or retracting the handle rotates the belts to extend or retract the wheels. Release mechanisms at opposite ends of the handle 25 lock the arms in the retracted position so that the handle can be used to carry the transporter with the wheels retracted. A release handle 31 operates spring-loaded pins to lock the arms 23 in the carrying or pushing positions.

  • Patent number: 6903311
    Abstract: In a method and apparatus for controlling an electric cooking appliance, a boost condition is initiated by increasing the power level of one or more electric heating means (2) to a maximum power level from a previous lower power level. Elapsed time (38) during cooling of the appliance since an end of an immediately previous period at the maximum power level is monitored, as is difference in power levels between the maximum power level and the previous lower power level. Duration (34) of the boost condition is set according to one of the elapsed time (38) and the difference in power levels and a level (36) of temperature boost in the boost condition is correspondingly set according to one of the difference in power levels and the elapsed time respectively.

  • Patent number: 6876767
    Abstract: Images of imprints, e.g. made by items of footwear, are displayed on a computer screen. Any identification features A-D which are present in the image are tagged and the length of all the lines 1-6 joining the tagged features are calculated and the distance information is added to a database together with the images themselves. The polygons defined by the lines 1-4 are independent of the positioning or orientation of the image and are used to retrieve images likely to originate from the same article by applying search criteria which retrieves records containing distances falling within selected bands.

  • Patent number: 6873446
    Abstract: An optical deflector comprises an aspheric deflecting lens (1, 13) of positive optical power. The deflecting lens (1, 13) has a first relatively short focal length giving rise to a first focal point (3) and a second relatively long focal length giving rise to a second focal point (5). Thus, a divergent beam (7) of light substantially at one of the first and second focal points is focussed by the lens at the other of the first and second focal points. Means (19), such as an electric motor, is provided for rotating the lens about an axis substantially coincident with one of the first and second focal points.

  • Patent number: 6869580
    Abstract: The method for generating a hydrogen-rich stream from hydrocarbon fuels, ultimately to produce hydrogen gas, involves the following two steps performed in a cyclic fashion: (1) pyrolysis of the hydrocarbon fuel to obtain a carbon-rich fraction and a hydrogen-rich fraction; and (2) oxidation of the carbon-rich fraction, or a portion of it, for heat generation. The method involves the following optional steps: (3) steam gasification of part of the carbon-rich fraction to produce additional amounts of hydrogen and carbon monoxide; (4) water-gas shift reaction to convert carbon monoxide to carbon dioxide with the simultaneous formation of additional amounts of hydrogen; and (5) steam reforming of light hydrocarbons that may be produced in step (1) to produce more hydrogen and carbon monoxide.
