    摘要: An assembly (38) comprises a vibration transducer (50) coupled to a substrate (58) which incorporates a circuit (62) electrically connected to the transducer (50). The substrate (58) is adapted to be coupled to a bending wave member (30) for converting actuator vibration into acoustic radiation or vice versa and has sufficient flexibility to allow bending wave coupling between the substrate (58) and the member (30).

    摘要: A skid-steer loader implement having a hydraulically actuated grapple component that includes an implement having first and second spaced apart pivot support structures and a hydraulically actuated grapple component pivotally secured to the second pivot support structure. A hydraulically actuated cylinder has one end of the cylinder pivotally secured to the first pivot support structure of the implement and is provided with a moveable piston integrally coupled to an output actuation rod that is pivotally secured at an end remote from the piston to the grapple component. The hydraulically actuated cylinder has supply/return ports adjacent the ends of the cylinder adapted to be alternately coupled to a high pressure hydraulic fluid supply or low pressure hydraulic fluid return. The hydraulically actuated cylinder has valve structure to hydraulically cushion movement of the piston and associated actuation rod as the piston moves past a supply/return port prior to being physically stopped at the ends of the cylinder. The actuation rod is provided with a protective shield to protect the actuation rod surface from hostile environmental intrusions by objects in the vicinity of the actuation rod during actuation. The grapple component includes a pivot shaft portion that is at least as wide or wider than a grapple tooth end of the grapple component. The second pivot support structure is comprised of a pair of bearing support elements spaced apart such that a grapple pivot shaft portion cooperates therewith to create a physical barrier to any material thing that may be gripped between the grapple component and implement.

    摘要: A rock raking apparatus which is adapted to be attached to a self-propelled vehicle and includes a rock raking unit with a toothed rotor and a rock collector bucket pivotably connected to the raking unit. The rotor is driven to propel rocks into the bucket. The raking unit includes a power-rotated brush positioned to deflect the propelled rocks into the rear of the bucket, to clean the surface of the rotor to prevent carryover and to prevent the formation of rock barricades at the entrance of the bucket to assure that the bucket is filled. The rotor is based on a cylindrical drum having a pattern of symmetrical radially extending teeth affixed to the peripheral surface thereof, with the pattern also being symmetrical so that the drum is reversible end for end when the leading edges of the teeth are worn. Double pivot mounts allow limited floating of the raking unit with respect to the bucket to accommodate uneven ground.

    摘要: A bending wave loudspeaker having an operating frequency range and a coincidence frequency which is above the operating frequency range, comprising a resonant panel having two generally orthogonal axes, vibration exciting means coupled to the panel to excite the panel into resonance along the one axis of the panel, and means restraining or preventing resonance along the other axis of the panel whereby the panel radiates an acoustic output which is of wide directivity along the one axis and of narrow directivity along the other axis of the panel.

    摘要: A loudspeaker includes a box-form structure made from stiff lightweight sheet material to define a plurality of faces, at least one face of the structure forming a panel-form bending wave acoustic radiator, and an electro-acoustic vibration transducer coupled thereto to apply bending wave energy to the radiator to cause it to radiate an acoustic output when an input signal is applied to the transducer. The box-form structure is collapsible, so that the box-form structure can be stored and transported in a flat form and erected as a box when required as a loudspeaker.

    摘要: A snowplow attachment for mounting to the front end of a vehicle that includes both a push blade operable during forward movement of vehicle and a pull blade operable during reverse movement of the vehicle. The pull blade drops down in front of the push blade such that pushed snow can then be pulled back. The snowplow can get up close to permanent structures such as buildings and remove snow therefrom. During the push mode, the pull blade is raised to avoid interference with pushed snow. The snowplow can include side plates located on the ends of the blades for containing the snow and prevent snow from escaping out the sides, thereby increasing the volume of snow moved by the plow during one sweep. According to one embodiment, the snowplow includes a push blade assembly that is adapted to mount directly on the vehicle and a movable pull blade carried by the push blade assembly. According to another embodiment, separate push blades and pull blades are arranged at separate locations on the attachment such that the entire attachment pivots to alternatively locate one of the blades close to the ground for selecting between pushing or pulling modes.
