A method for recovering sulfuric acid from a titanium sulfate waste liquor by diffusion dialysis in a diffusion dialytic cell provided with anion exchange membranes, which comprises subjecting the titanium sulfate waste liquor to precision filtration to remove a solid content having a particle size of at least 0.1 mu m to a level of not more than 100 mu g/ l , and placing the filtered liquor to ...

A dental floss holder is in the form of a box (20) with a drawer (22) in it. The bottom of the drawer includes a hub (38) which is spring biased to push a bobbin (24) mounted thereon toward an opposite side of the box. The bias is such that the bobbin drags with a predetermined force on an opposite side of the box to maintain tension in the floss. A result is that the bobbin does not unwind while ...

An optical waveguide (1) having a detour is disposed at either or both of the light-receiving and light-emitting ends of a dispersion optical system in a spectroscope. Even though light being propagated through the optical waveguide has specified polarizing characteristics, the light is depolarized by passing through the optical waveguide and many times reflecting therein. Accordingly, unpolarized...

A controller for reducing acceleration slippage of a driven wheel starts the throttle-valve control, the brake control, and the engine output torque control when acceleration slippage is detected.
