Abstract: A moustache or beard brush device includes a handle member having a sleeve atop its upper face, said sleeve having at least one open end for the insertion of a user's finger. The handle member further includes a lower or bottom face, opposite the upper sleeve face. That lower face includes a plurality of bristles extending downwardly therefrom for use in grooming its wearer's moustache and/or beard.

Abstract: A liquid soap or lotion applicator for hard to reach areas of the body which includes in combination a substantially rigid elongated tubular handle with a low pressure squeeze bulb secured to one end of the tubular handle for forcing air under low pressure through the tube handle, and a hollow head connected to the opposite end of the tubular handle. The head is provided with a reservoir that communicates with the hollow interior of the tubular handle and is further provided with a removable access for pouring liquid soap or lotion into the reservoir. A porous applicator is removably secured to head with the interior surface of the applicator exposed to the reservoir whereby liquid in the reservoir will be forced through the porous applicator for application to the body when the bulb is squeezed.

Abstract: The ratio of silica to alkali in silicate liquors is increased, for example to convert alkaline grades to neutral grades, by passing the liquors through an electrodialysis stack comprising alternating cation exchange membranes and bipolar membranes mounted between an anode and a cathode, the membranes forming a concentrating cell between the anion exchange side of the bipolar membrane and the adjacent cation exchange membrane and a diluting cell between the cation exchange side of the bipolar membrane and the adjacent cation exchange membrane, the method comprising passing the silicate liquor through the diluting cells in the stack and passing water or an aqueous solution through the concentrating cells, whereby the silicate liquor is caused to lose alkali metal ions to the concentrating liquor and receive hydrogen ions from the bipolar membranes.

Abstract: The ratio of silicate to alkali in silicate liquors is increased, for example to convert alkaline grades to neutral grades, by passing the liquors through an electrodialysis stack comprising alternating anion exchange membranes and cation exchange membranes mounted between an anode and a cathode, the membranes being spaced apart to provide cells through which a fluid can be passed, the method comprising passing the silicate liquor through those cells having their anion exchange membranes on the anode side and passing water or an aqueous solution through the other cells, whereby the silicate liquor is caused to lose alkali metal ions.

Abstract: The ratio of silica to alkali in silicate liquors is increased, for example to convert alkaline grades to neutral grades, by passing the liquor through an electrodialysis stack comprising spaced ion-exchange membranes mounted between an anode and a cathode, the membranes forming cell triplets of a concentrating cell between an ion-exchange membrane and a fine cation exchange membrane, a diluting cell between the first cation exchange membrane and a second cation exchange membrane and a proton donor cell between the second cation exchange membrane and an adjacent anion-exchange membrane, the method comprising passing the silicate liquors through the diluting cells in the stack, passing water or an aqueous solution through the concentrating cells and passing an acidic solution through the proton donor cells whereby the silicate liquor is caused to lose alkali metal ions to the concentrating liquor and to receive hydrogen ions from the proton donor liquor.
