Title: Inductive linear motion displacement transducer - uses shaped ferrite core winding and moving ring which affects winding inductance to give nonlinear characteristic
Inventor: ZABLER ERICH DR ING
IPC: G01D5/20
Filed: 1976-07-09
Abstract: A linear movement inductive displacement transducer with a non-linear input output characteristic depends on the inductance change caused in a single winding round a shaped ferrite core when an electrically conductive ring is moved along the winding. Basically, an E-shaped ferrite core (10) has a winding (12) on its centre shank (11) and an electrically conductive ring (13) moves along this winding, around it but not in contact with it, as the movement to be measured occurs. The winding inductance - monitored by a circuit - changes as this happens, with the non-linear characteristic required. Different shapes of ferrite core, a moving cylinder rather than a ring, an array of windings and other variations are presented.

Title: Beam balance measuring instrument - has angular acceleration compensation by selection of component positions and moments of inertia
Inventor: SMITH JAMES E
IPC: G01G23/06
Filed: 1976-08-31
Abstract: A beam balance or accelerometer type device has a stand. An arm mounted on a horizontal axis is placed away from the centre of gravity of the beam (B) and a beam counter weight ensuring static equilibrium in the absence of loading is designed for compensation of vibration-induced angular acceleration effects. This is achieved without use of filters or directional discriminators. The counter weight is so arranged as to rotate about an instantaneous axis parallel to the arm axis. It is connected to the arm by a support so that their rotations w.r.t. each other and w.r.t. the frame are coordinated. The suspension points and component moments of inertia are chosen so as to reduce relative motion between beam and frame resulting from angular movements.
