    摘要: The present invention provides a centrifugal fan including a hub adapted for rotation about a central axis and a plurality of blades arranged about the central axis and coupled for rotation with the hub. Each of the blades includes a curvature in a plane that extends through the blade and is tangent to a cylinder which extends through the blade and is centered along the central axis.

    摘要: This invention is characterized by a very compact blower assembly architecture designed to operate at low Reynolds numbers. The assembly includes an impeller with forward-curved blades and a hub that is shaped to minimize the overall package volume of the assembly. The impeller is driven by a low-power, brushed, direct-current motor. A shroud part includes a generally cylindrical inlet that directs the air into the impeller, and a surface that forces the air leaving the impeller to turn from a generally radial and tangential direction to a generally axial and tangential direction. The shroud part directs the air into a single stage of stator blades that reduces the tangential component of the air velocity and produces a static pressure rise.

    摘要: A hockey training device is provided. The training device includes a substantially flat sheet with a smooth upper surface. The present invention includes a plurality of elastic band suspended to the upper surface. A first vertical post and a second vertical post may be attached to the flat sheet so that the elastic band is secured about the first and second vertical posts. The elastic band includes a front surface facing towards a center portion of the flat sheet. Therefore, a puck may be passed towards the elastic band and the elastic band rebounds the puck towards the user.

    摘要: An apparatus for drawing blood from a finger includes a flexible band, at least a portion of which is adapted to surround a portion of a finger. A remaining portion of the apparatus is disposed under at least one joint of the finger. The apparatus provides sufficient strength along its longitudinal length to restrict a child or other person from excessively bending the joint when the finger restraint is in position. After a puncture is provided near the tip of the finger, the apparatus is then squeezed to help force an additional quantity of blood to flow out through the puncture. After the blood sample is taken, the apparatus continues to “restrain” the finger until a required bandage is applied. A few of the many possible modifications are also shown.

    摘要: A viewing device (10) includes a body enclosing a first reflective surface or mirror (40), second reflective surface or mirror (42) and a mechanism for securing the body to a conventional sighting device or telescope (82) on a firearm. First mirror (40) is adapted to direct an incoming light beam (44) onto second mirror (42) so that an outgoing light beam (70) is angled relative to the incoming light beam (44). In use, viewing device (10) can be releasably attached to rear end (80) of telescope (82) and allows a user (90) to remain partially hidden behind obstacle (92) whilst viewing through sighting device (82) and using the firearm. The angular offset of respective light beams (44, 70) is between 35° and 60°.

    摘要: A securing arrangement for a tool (7) of an agricultural tillage implement of a type having a tapered interconnection between a socket (5) on the tool and an adaptor piece (3) adapted for mounting onto a tine (1) of the tillage implement. The adaptor piece (3) has a recess (9) which can be an aperture or a pair of transverse arcuate slots (31) for receiving a retaining pin(11). The socket (5) on the tool has notches (15) on its opposed sides and a portion (13) on the retaining pin in use engages into at least one of the notches (15) to prevent disengagement of the socket (5) from the adaptor piece (3). The adaptor piece can be integral with the tine.
