摘要： A handle for a wand of a vacuum cleaning appliance includes a handgrip portion and a conduit for receiving an air flow. The handle includes an aperture for admitting ambient air into the conduit. A first valve occludes a first portion of the aperture, and a second valve occludes a second portion of the aperture. A control mechanism moves the first and second valves away from the aperture to admit ambient air into the conduit. To reduce the force required to move the valves away from the aperture, the control mechanism is configured to move the second valve away from the second portion of the aperture before moving the first valve away from the first portion of the aperture.

摘要： Cyclonic separating apparatus for a cleaning appliance such as a vacuum cleaner has a longitudinal axis, an upstream cyclonic separator and a downstream cyclone assembly. The downstream cyclone assembly comprises a plurality of cyclones arranged in parallel with one another. The downstream cyclones are arranged in a first set in which each cyclone has a longitudinal axis inclined at a first angle (α) to the longitudinal axis of the cyclonic separating apparatus and a second set, in which each cyclone has a longitudinal axis inclined at a second angle (β) to the longitudinal axis of the cyclonic separating apparatus. The second angle (β) is greater than the first angle (α). The invention allows the downstream cyclone assembly to be compactly packaged.

摘要： A vacuum cleaning appliance includes a vacuum cleaning head having a suction opening, the head having a first state and a second state, a fan unit for drawing an air flow through the suction opening, and a control assembly for controlling the state of the head. The control assembly includes a user-operable valve for increasing temporarily an air pressure within an airflow path extending from the suction opening to the fan unit, a pressure chamber having an interior volume in fluid communication with the airflow path, the pressure chamber being moveable from an expanded configuration to a contracted configuration in response to a pressure difference between the interior volume and ambient air, the pressure chamber being biased towards the expanded configuration, and a control mechanism for allowing the pressure chamber to move to the contracted configuration in response to a first operation of the valve to place the head in one of the first and second states, and for preventing the pressure chamber from returning to the contracted configuration in response to a second operation of the valve to place the head in the other of the first and second states.

摘要： Methods, apparatus and systems for detecting charged particles and obtaining tomography of a volume by measuring charged particles including measuring the momentum of a charged particle passing through a charged particle detector. Sets of position sensitive detectors measure scattering of the charged particle. The position sensitive detectors having sufficient mass to cause the charged particle passing through the position sensitive detectors to scatter in the position sensitive detectors. A controller can be adapted and arranged to receive scattering measurements of the charged particle from the charged particle detector, determine at least one trajectory of the charged particle from the measured scattering; and determine at least one momentum measurement of the charged particle from the at least one trajectory. The charged particle can be a cosmic ray-produced charged particle, such as a cosmic ray-produced muon. The position sensitive detectors can be drift cells, such as gas-filled drift tubes.

摘要： A vacuum cleaning head includes a pressure chamber having a first chamber section and a second chamber section which is moveable relative to the first chamber section in response to a pressure differential thereacross from a first position to a second position, and a control mechanism located within the pressure chamber. The control mechanism has a first state for inhibiting the movement of the second chamber section in response to said pressure differential beyond a third position intermediate the first and second positions, and a second state for allowing the second chamber section to move in response to said pressure differential to the second position. The control mechanism is arranged to change between the first and second states in response to a movement of the second chamber section from the third position. This can allow the pressure chamber to toggle between different configurations through varying the pressure differential across the second chamber section, for example to raise or lower part of the cleaner head, or to selectively activate or deactivate an agitator.

摘要： A handle for a wand of a vacuum cleaning appliance includes a handgrip portion and a conduit for receiving an air flow. The handle includes an aperture for admitting ambient air into the conduit. A first valve occludes a first portion of the aperture, and a second valve occludes a second portion of the aperture. A control mechanism moves the first and second valves away from the aperture to admit ambient air into the conduit. To vary the air flow into the conduit, the control mechanism includes a first manually operable actuator located on the handle for moving both of the first and second valves away from the aperture, and a second manually operable actuator is located on the handle for moving only one of the first and second valves away from its respective portion of the aperture.
