Abstract
Abstract A mass and force meter having a frame, a load support and a digital computing device, a first and a second electrically excited, transversely vibrating string, first transmission elements transmitting the mass or force to be measured to said strings, second transmission elements transmitting a pre-loading force to said strings, so that the resultant frequency variations caused by the application of said mass or force are used in the computing and display device for computation of the magnitude of said mass or force, said first transmission elements having a first and a second branch, a first guide fixed to the frame, said first string having one end fastened to said frame and the other end connected to one end of said second string, to said first guide and to said first branch of said first transmission elements, a second guide fixed to the frame, the other end of said second string being connected to said second guide, to said second transmission elements and to said second branch of said first transmission elements.

Claim 3
Dependent Claim
183 words
A mass and force meter having a frame, a load support and a digital computing device, a first and a second electrically excited, transversely vibrating string mounted vertically in said frame, first transmission elements transmitting the mass or force to be measured to said strings, second transmission elements transmitting a pre-loading force to said strings, so that the resultant frequency variations caused by the application of said mass or force are used in the computing and display device for computation of the magnitude of said mass or force, said first transmission elements having a first and a second branch, a first guide mounted horizontally and fixed to the frame, said first string having one end fastened to said frame and the other end connected to one end of said second string, to said first guide and to said first branch of said first transmission elements, a second guide mounted horizontally and fixed to the frame, the other end of said second string being connected to said second guide, to said second transmission elements and to said second branch of said first transmission elements.
