Abstract: 176,614. Minton, O. Feb. 1, 1921. Drying materials in long lengths.- A method of sealing the inlet and outlet openings of a vacuum chamber through which sheet material is passed to be dried or otherwise treated consists in forcing a fluid such as mercury, water, air, or steam, which has no deleterious effect upon the material, through the openings under sufficient velocitv to prevent admission of air into the chamber. Fig. 1 shows the method applied to apparatus for drying paper in which the web of paper is passed between felts 8, 9 over heated rotary drums 2, 3 within the vacuum chamber 1. The inlet seal comprises a housing 11 containing the fluid and communicating through a passage 13 with the chamber which is connected by a pipe 31 with a barometric seal 30.

[Class 56.] Relates to the manufacture of glass containing boron and barium, and consists in adding these substances to the batch, not in the form of separate compounds but in the form of a barium borosilicate. The barium borosilicate is made by fusing a mixture composed of 35-50 per cent of silica, 8-20 per cent of boron trioxide, and 15-30 per cent of barium oxide, together with 3-7 per cent of alumina and 8-12 per cent of alkali. The mixture is fused in a tank furnace at as low a temperature as possible, and the resulting glass is run into water to form granulated cullet, which is then dried and ground.
