Patent number: 7669483Abstract: Tangential forces present at the mating area between a clamp-on transducer and a pipe can be made very small in order to provide a higher quality, more stable acoustic coupling. In some cases this is accomplished by providing a low friction bearing on a surface of a transducer housing. This bearing may be a slippery surface portion, or may involve a rotary bearing mounted on the housing. In other cases, where a steel pipe is used, pairs of permanent magnets coupled by a yoke can provide the desired clamping force directed solely along a radius of the pipe.Type: GrantFiled: February 27, 2009Date of Patent: March 2, 2010Inventor: Murray F Feller

Patent number: 7594304Abstract: A clamping device (1) for connection in which a housing (4) rotatably accommodates a worm screw (5) to mesh with an array of teeth portion (6) of a strap band (3). The strap band (3) is diametrically contracted upon operating the worm screw (5) to wind the strap band (3) around a connecting portion (2). One end portion of the strap band (3) in which the array of teeth portion (6) resides, is formed into a wavy and concavo-convex configuration in its width direction, thus increasing a meshing area of the array of teeth portion (6) against the worm screw (5). This makes it possible for the strap band (3) to cope with a situation in which the strap band (3) is required to tightly wind the connecting portion (2) with a high tightening force.Type: GrantFiled: April 12, 2004Date of Patent: September 29, 2009Assignee: Takagi Mfg. Co., Ltd.Inventors: Norio Ito, Mikio Niwa
