  • Publication number: 20100268676
    Abstract: A method for the automatic examination of knowledge system hierarchies is disclosed. A target TMK hierarchy is represented as a plurality of records in a database. A second TMK hierarchy (a “critic”) is constructed of tasks, subtasks, methods, procedures and actions. The critic hierarchy includes actions that retrieve and examine at least one record of the database representing the target hierarchy. The examination of the record provides a result. The result is of the form of a modification of the processing within the critic hierarchy or of the form of a report or a modification of the target hierarchy's elements, namely, tasks, methods, procedures, actions, class structures, or the relationship between the elements. The report is in a form suitable for printing or displaying on a computer monitor. The modification of the target hierarchy is of the form of writing one or more records to the database representing the target hierarchy.

  • Publication number: 20100200006
    Abstract: A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.

  • Publication number: 20100192916
    Abstract: A sleeve valve (13) slides axially along the cylinder (10) while simultaneously rotating about the axis of the cylinder (10). The sleeve valve (13) has sleeve ports (23). A piston (14) reciprocates within the sleeve valve (13) and within the cylinder (10) to define a combustion chamber. A sleeve valve driving mechanism (24, 25, 26, 27, 28, 29, 30, 31) drives the sleeve valve (13) to slide axially along and rotate in the cylinder (10) in timed relationship with reciprocation of the piston (14) in the cylinder (10). The sleeve valve (13) is driven between two extreme positions in each stroke and the sleeve driving mechanism (24, 25, 26, 27, 28, 29, 30, 31) is operable to vary in locations the two extreme positions.

  • Publication number: 20100089364
    Abstract: A method and apparatus for providing automatic pressure balancing of an internal combustion engine. The engine includes cylinders, fuel injector valves provided to selectively deliver fuel directly into the cylinders, fuel-balancing valves each fluidly connected to the fuel injector valves for controlling the fuel delivered to the fuel injector valves and cylinder pressure sensors each mounted to one of the cylinders. The method comprises an automatic pressure balancing procedure including the steps of monitoring a cylinder pressure in each of the cylinders, determining a peak combustion pressure produced in each of the cylinders, calculating a mean peak pressure produced in all of the cylinders, calculating a pressure difference between the mean and the peak pressure and incrementally adjusting the fuel delivered by one of the fuel-balancing valves to the corresponding fuel injector valve mounted to the cylinder having the pressure difference larger than a predetermined pressure value.

  • Patent number: 7370630
    Abstract: The present invention relates (with reference to FIG. 1) to an internal combustion engine in which a combustion chamber (12) can be connected to a reservoir (16) for storing compressed air. Gas flow control valve means (15) controls flow between the chamber (12) and reservoir (16) so that air pressurised in the chamber (12) can be relayed to charge the reservoir (16) and pressurised air can be delivered to the chamber (12) to drive piston (10). The chamber (12) is also used for combustion of fuel. The invention also relates to a valve mechanism for controlling the flow of pressurised air between the chamber (12) and reservoir (16), in which a balancing force is applied to the gas flow control valve (115) to cancel the force on the valve (115) arising from the pressure applied to the back face of the valve (115).

  • Patent number: 7204102
    Abstract: A method of forming an air-tight scal between two pieces of glass is described. It comprises the steps of: (a) introducing a layer of indium or indium alloy between opposing surfaces of the glass pieces; and (b) heating the indium or indium alloy layers and the glass pieces, preferably under vacuum, to a temperature, generally around or below 220° C., to melt the layers to form the seal between the pieces. The method is suitable to form a relatively small air-type seal between two glass panes or sheets, and is particularly suitable for the formation of evacuated double glazing units. Optionally, an additional metal layer is located between the indium or indium alloy layers.
