Abstract: A woven geosynthetic fabric having a weft direction and a warp direction, comprises weft yarns woven in the weft direction and warp yarns woven in the warp direction interweaving the weft yarns to form a fabric having comparable modulus; the warp yarns comprising a high modulus monofilament yarn having a tenacity of at least 0.75 g/denier at 1% strain, at least 1.5 g/denier at 2% strain, and at least 3.75 g/denier at 5% strain as determined in accordance with ASTM International Standard 4595.

Abstract: A separator for removing dirt particles from an airflow, the separator comprising a first separation stage having an impeller, and a second separation stage having one or more cyclone bodies arranged in parallel, the first separation stage being upstream of the second separation stage. The impeller generates the airflow through the separator and concentrates the dirt particles within the airflow to produce a clean portion and a dirty portion of airflow, and wherein only the dirty portion of airflow is passed through the second separation stage.

Abstract: A hairdryer including: a handle; a body comprising a duct extending within the body; a fluid flow path extending through the duct from a fluid inlet through which a fluid flow enters the hairdryer to a fluid outlet for emitting the fluid flow from a front end of the body; a primary fluid flow path extending at least partially through the body from a primary fluid inlet through which a primary fluid flow enters the hairdryer to an annular primary fluid outlet at a front end of the body; a fan unit for drawing the primary fluid flow through the primary fluid inlet; and an attachment for adjusting at least one parameter of fluid emitted from the hairdryer, the attachment being attachable to the hairdryer so that the attachment protrudes from the front end of the body, wherein the attachment is configured to inhibit the generation of the fluid flow.

Abstract: An apparatus for removing dirt from an airflow, the apparatus comprising an air inlet, an impeller for generating an airflow through the apparatus and for generating swirl within the airflow, the swirl throwing the dirt radially outwards and producing an outer dirty portion and an inner clean portion of airflow downstream of the impeller, and one or more splitters downstream of the impeller that bifurcate the airflow, separating the outer dirty portion from the inner clean portion.

Abstract: A rotor assembly having a shaft, a bearing assembly, an impeller and a shroud. The impeller and the bearing assembly are mounted to the shaft, and the shroud is mounted to the bearing assembly so as to cover the impeller.

Abstract: A rotor that includes a rotor core assembly secured to a shaft. The rotor core assembly includes a magnet and an end cap secured to an end of the magnet. Each of the magnet and the end cap has a bore into which the shaft extends. The end cap forms an interference fit with the shaft. The magnet forms a clearance fit with the shaft and an adhesive is located in the clearance between the magnet and the shaft. Additionally, a method of manufacturing the rotor. The method includes inserting the shaft into the bore of the end cap. An adhesive is then introduced into the bore of the magnet and the shaft is inserted into the bore of the magnet so as to cause adhesive to be drawn into the clearance defined between the magnet and the shaft.

Abstract: A flow restrictor for use on a pilot operated relief valve (PORV) assembly with a pilot valve that regulates operation of a main valve to reduce pressure in a system or vessel. In one embodiment, the flow restrictor is configured with a plurality of flow modifying regions, namely, a first region and a second region that is spaced apart from the first region. These regions are configured to generate flow at the outlet of the flow restrictor that induces operation of the pilot valve that is favorable for operation of the main valve. In one example, the first region and the second region define, respectively, a first flow area and a second flow area for the flow pathway, wherein each are configured to assign a ratio of the second flow area to the first flow area with a value of less than 10.

Abstract: A rotor assembly that includes a shaft to which are mounted an impeller and a bearing assembly. The bearing assembly is located at least partly within the profile of the impeller so as to reduce loading of the bearing assembly as well as reduce the cantilever length of the rotor assembly.

Abstract: A hairdryer including: a handle; a body comprising a duct extending within the body; a fluid flow path extending through the duct from a fluid inlet through which a fluid flow enters the hairdryer to a fluid outlet for emitting the fluid flow from a front end of the body; a primary fluid flow path extending at least partially through the body from a primary fluid inlet through which a primary fluid flow enters the hairdryer to an annular primary fluid outlet at a front end of the body; a fan unit for drawing the primary fluid flow through the primary fluid inlet; and an attachment for adjusting at least one parameter of fluid emitted from the hairdryer, the attachment being attachable to the hairdryer so that the attachment protrudes from the front end of the body, wherein the attachment is configured to inhibit the generation of the fluid flow.

Abstract: A hairdryer comprises a handle, a body comprising a duct, a fluid flow path extending through the duct and from a fluid inlet through which a fluid flow enters the hairdryer to a fluid outlet for emitting the fluid flow from a front end of the body, a primary fluid flow path extending at least partially through the body from a primary fluid inlet through which a primary fluid flow enters the hairdryer to a primary fluid outlet; a fan unit for drawing the primary fluid flow through the primary fluid inlet, and wherein the fluid flow is drawn through the fluid flow path by fluid emitted from the primary fluid outlet, and an attachment for adjusting at least one parameter of fluid emitted from the hairdryer, the attachment being attachable to the hairdryer so that the attachment protrudes from the front end of the body.

Abstract: A rotor assembly having a first component and a second component. The second component is secured within a bore of the first component by a first adhesive and a second adhesive. The first adhesive forms an annular seal between the first component and the second component, and the second adhesive extends from the first adhesive and has a lower viscosity than that of the first adhesive.
