    摘要： A downhole tool (10) comprises a body (12) defining a bore. The body includes a valve arrangement (18) including flow ports (24) in the wall of the body. The ports may be opened or closed. In addition, a variable flow restriction (30) is provided in the bore (14), the degree of restriction tending to decrease as flow across the restriction increases. The variable flow restriction may be utilized to actuate the valve arrangement.

    摘要： A cyclonic separating apparatus includes a cyclonic separator for separating dirt and dust from an airflow, an inlet to the cyclonic separator and a shroud comprising a wall having a multiplicity of through-holes forming an outlet from the cyclonic separator. The apparatus also includes a plurality of separate passageways provided immediately downstream of the through-holes. By providing this arrangement, the separate passageways can be located around other parts of the cyclonic separating apparatus inwardly of the shroud, allowing for better packaging of the components of the cyclonic separating apparatus. The shroud may be reduced in size because some of the space previously required for a single, large passageway can be used for other components of the cyclonic separating apparatus such a collector or a cyclone. The reduction in size of the shroud in turn allows for the cyclonic separating apparatus to be more compact.

    摘要： Accurate sensing of ice readiness in an ice maker is accomplished using, as an ice readiness sensor, a capacitance bridge circuit having a first capacitor connected as a first bridge arm a second capacitor connected as a second bridge arm, a tunable capacitor connected as a third bridge arm and a probe connected as a fourth bridge arm. The probe includes a pair of electrode strips placed in close proximity to the belt of a belt ice maker. First and second bridge arms are connected at a first bridge node first and third bridge arms are connected at a second bridge node, second and fourth bridge arms are connected at a third bridge node, and third and fourth bridge arms are connected at a grounded fourth bridge node. The first and fourth bridge nodes are input terminals for receiving an AC drive signal from an AC source, and the second and third bridge nodes are output terminals. A signal processor, coupled to the second and third bridge nodes, includes an amplifier having its output coupled to a rectifier, and an output filter capacitor coupled to the rectifier. An output signal from the signal processor is supplied to a controller which controls the movement of the belt.
