摘要:
There is provided a musical instrument having a tubular body and a handle. The tubular body has an annular wall that defines a sound chamber. The handle is designed to shelter the hand of the player or serve as a mounting for use with a mounting cradle. The thickness of the tubular wall and the dimensions of the sound chamber may be modified to produce various sound qualities and pitches. Preferably, the musical instrument produces the characteristic sound of the traditional “clave.”

There is provided a showerhead device that includes a shower stem connector, a water/air mixing chamber, and an outlet cap. The shower stem connector includes a water inlet to receive water from a standard shower plumbing system and an air intake opening to receive air from outside the device. The preferred embodiment features an air intake opening located near the water inlet on the shower stem connector. A user can adjust the air intake knob in order to vary the amount of air that enters the device and mixes with the water flow. As the water progresses through a nozzle in the device, the speed of the water is increased by the decrease in diameter of the nozzle orifice. The water mixes with the air and the combination of water/air hits a plate on the inner wall of the outlet cap within the mixing chamber. This oxygenation of the water provides for a better water flow though the showerhead device. The mix of water and air provides for a stronger water flow and a better shower experience for a user. By having the air intake further upstream, it enables a user to adjust the amount of air mixed in.

A rechargeable hand held or floor supported multi surface cleaner is adapted to use rechargeable, dry cell batteries or a line cord connected supply to power one or more rotating power drives or counter rotational or linear power drives and cleaning brushes. The unit can dispense hot, warm or ambient detergent solution in order to facilitate cleaning. A docking station is provided to recharge the cleaning unit batteries, to heat the detergent solution and to refill the unit's detergent bottle from a larger interchangeable reservoir located in the docking station. Disposable as well as non-disposable attachments are provided with extension wands to clean various surfaces including conditions and hard to reach areas. A floor cleaner component uses the same interchangeable detergent bottle for cleaning.

The present invention is related to interactive training. In one embodiment, a training system presents a stored scenario to a user via a terminal. The user is provided with the ability to intervene and stop the pre-recorded scenario to identify an error in handling the situation presented in the scenario and/or an opportunity presented in the scenario. Once the user has intervened, the user can be presented with a question regarding the opportunity and/or error. The user is scored based in part on the number of errors and/or opportunities that the user identified and optionally on the user's response to the question.
摘要:
This invention relates to a dual phase rubber composition and pneumatic tire with a rubber sidewall thereof, namely a dual phased non-black colored rubber composition composed of a first pre-formed elastomer phase comprised of butyl-type rubber and EPDM rubber containing a dispersion therein of reinforcing filler comprised of a particulate amorphous precipitated silica and a second pre-formed elastomer phase comprised of a nanocomposite of natural rubber containing a dispersion therein of exfoliated clay platelets. Said exfoliated clay platelets may be substantially oriented within the tire sidewall in a parallel direction to each and may also be substantially oriented in an annular direction about the axis of the tire. The tire sidewall rubber composition may contain at least one additional elastomer which may be included in either or both of said elastomer phases. Such tire sidewall rubber composition may contain a non-black colorant pigment, such as for example a white colored titanium dioxide pigment. The dual phased tire sidewall rubber composition is prepared by a phase mixing process comprised of pre-blending said butyl-type rubber and EPDM rubber together with said precipitated silica reinforcing filler to form a pre-mix thereof, and thereafter mixing therewith said nanocomposite as a pre-formed blend of natural rubber and exfoliated clay platelets.
