Title: End weighted reed sound transducer
Inventor: LOFTIN ROYFORD A
IPC: H04R17/00
Filed: 1983-07-23
Granted: 1989-03-07
Abstract: Preferably, there are four such reeds disposed in a respective quadrant of the base of the hydrophone and cantilevered from the base.  The topmost edge of each reed is received in a respective groove of the associated weight.  Sound waves incident upon the hydrophone produce radially-diverted forces in its cylindrical wall which is normal to waves from all directions.  The force produced is a function of the wall area upon which the wave is incident.  The force causes displacement of the base relative to the inertial weights and, consequently, produces the bending of the reeds.

Abstract: A dispersion of fine particles of an ethylene polymer or ethylene polymer composition dispersed in a hydrocarbon solvent, wherein the ethylene polymer or ethylene polymer composition has an acid value of 0.3 to 75 mg-KOH/g as a whole and a crystallinity of at least 45% as determined by the X-ray diffractometry and has an average dispersed particle size of 0.3 to 20 um and a concentration of 15 to 60% by weight may be used as an additive to oily printing inks.
