摘要： A bicycle bell is revealed. The bicycle bell consists of a fixing element (10), a struck block (20) and a striking element (30). The fixing element (10) is provided with a base (11) on whose bottom side a connecting portion (12) is arranged, on whose top side a positioning column (13) protruding from the center thereof is arranged and on whose one side an extending seat (14) is formed, so that the striking element (30) which is elastic and resettable can be mounted on the extending seat (14). The struck block (20) is made of metal and formed as a triangular body having a hollow space (21) inwardly. The struck block (20) is provided with three struck segments (22) surrounding the outer side of the hollow space (21) and connected with each other in such a manner that the respective connecting part is formed as a turn. A cantilever (23) is extending from at least one of the struck segments (22) into the hollow space (21), and an opening (24) is arranged on one side of the struck block (20) in such a way that the opening (24) goes through the said struck segment (22).

摘要： A device and method for cleaning baghouse filters using a shock wave vortex is disclosed. In one embodiment, high pressure fluid enters the housing of the device through an inlet tube in axial alignment with a resonance chamber within the housing. The high pressure fluid enters and exits a resonance chamber causing a collision with the fluid from the inlet tube to generate a shock wave. The shock wave is directed downward by the housing through the lower opening of the housing and towards a baghouse filter as a ring-shaped shock wave vortex. The ring-shaped shock wave vortex concentrates cleaning energy along the side material of the baghouse filter.

摘要： A musical percussion instrument consists of more than three integrally formed, substantially linear, elongate sections. The sections are not colinear, but are substantially coplanar. The sections form a shape, and are made from a material (typically metal or a ceramic material) which has vibrational properties such that, when one section is struck with a mallet, the instrument emits a musically concordant sound. The mathematical analysis leading to alternative designs for such an instrument having five sections (termed a ''pentangle''), made by bending mild steel rod, is presented. The sound produced by the instrument may be acoustically or electronically amplified. An array of ''pentangles'' (60), each tuned to different pitch, may be assembled to provide the equivalent of a keyboard instrument.
