Title: Data indicator for weighing machine - has liqiud crystal cell with transparent electrodes having structured profiles for symbol formation
Inventor: RIET ALOYSIUS JOHANNES VAN
IPC: G01G23/37
Filed: 1974-12-23
Abstract: The direction of travel of the light beam (26') passing undisturbed through the liquid crystal cell (20) forms an angle of inclination (alpha) with the axis (28) of the fibres (27) in the fibre optic plate (22). This angle is greater than the critical angle of such an inclination position at which a total reflection occurs in the fibre material (27) at the boundary surface to the light absorbing embedding material of the fibres in the fibre optic plate. This plate forms the cell end plate on the light output side of the liquid crystal cell. An optical deflector e.g. a prism is positioned at the light inlet side of the cell in order to guide the light (26, 26', 26") an angle (delta) through the cell. The design increases the contrast of the formed symbols and hence their legibility.

Title: Helical valve spring with unequal coil dias. - dampens spring oscillation to internal shear stress and frictional contact when compressed (BR030876)
Inventor: ZWIRNER ECKHARD ING GRAD
IPC: F16F1/04
Filed: 1975-05-15
Abstract: The helical valve spring is coiled in such a way that the two end sections have coil dias. which are different from the dia. of the spring coils in between. This produces two contact areas between the unequal coil dias. where friction occurs when the spring is axially compressed or expanded. Since the frequency of valve operation is so great that vibrating valve springs would affect efficient valve function, damping of the spring oscillation is required. This axial oscillation of the spring coils which is produced by the internal shear stress due to compression, is dampened by the friction between the coils of unequal diameter which are in contact when the spring is compressed.
