IPC: C03B17/06
Filed: 1926-03-23
Abstract: 249,863. Heuze, C. March 28, 1925, (Convention date]. Delivering molten metal; rolling.-In a method of making plate. glass, a storage tank is interposed between the melting-tank and the rolling apparatus, and charges of glass are drawn from the storage tank as required. This tank is of large size so that a bulk of glass of even composition is available for an extensive working period. Delivering molten metal. The glass is made in a tank 14 and flows through a spout 15 into a storage tank 2 the bottom of which is pivoted on an axis 3 situated near an outlet slot S. The bottom can be moved by suitable means and when it is raised, glass is discharged through the outlet S, a gate 1 being provided to assist in controlling the discharge. The bottom may be fixed instead of being movable, and the outlet slot may be formed in the bottom and closed by a gate. In another modification, the storage tank may be made to rock about a transverse or a longitudinal axis, the tank being tilted when it is required to discharge glass. In a further modification, the outlet slot is formed in the side of the storage tank and the axis about which the tank is tilted passes close to the slot, so that the movement of a pouring-lip, which is attached to the slot, is reduced to a minimum when discharging glass. The trunnions about which this form of tank turns are made hollow, and one is used to admit glass while the other serves as an inlet for the. gas used for heating the tank. Rolling. The Specification as open to inspection under Sect. 91 (3) (a) also describes a rolling-apparatus in which glass, issuing from the outlet S in the tank 2, flows over an inclined table 4 to rollers 6, 7 by which it is formed into a sheet. The table is pivoted on an axis 5 close to and parallel with the rollers, and its inclination can he adjusted. The sheet, as it leaves the rollers 6, 7, is led by carrier rolls 8, 9 on to a conveyer table 10 which moves under the rollers at the same speed as that of the sheet of glass. A shearing-device 12 cuts the sheet into lengths which are conveyed by the moving table 10 to a leer. After removal of the glass, the table returns through a tunnel G and is raised by an elevator 13 into position to be run under the rollers to receive a new sheet. The table 10 may be returned along a parallel track instead of through a tunnel. This subject-matter does not appear in the Specification as accepted.

Title: Continuous diffusion process for the production of sugar from sugar beet
IPC: C13B10/10
Filed: 1944-05-08
Abstract: 593,742. Sugar extraction. SILVER, H. F. May 8; 1944, No. 8690. [Class 127] In a continuous diffusion process for the production of sugar from sugar beet of the type in which cossettes travel through a succession of treatment stages through which the treating juice flows progressively in a general direction opposite to the direction of the cossettes, each treatment stage includes alternate downward and upward courses into which the juice is introduced intermediate the ends of the downward course the juice travelling concurrently with the cossettes until it is withdrawn intermediate the ends at the succeeding upward course, drained from the cossettes and subsequently brought into contact with them at an intermediate position in the downward course of the next treatment stage. As shown, the apparatus consists of a series of vertical cells 6 arranged in tiers and sealed from the atmosphere. Cossettes are fed into a hopper 7 and carried by an endless conveyer 12 through the cells being finally discharged at 9. Water is fed in at 8 and circulates through the cells and launders 15 being finally discharged at 10. The launders 15 are U-shaped conduits disposed horizontally and alternately mounted on opposite sides of the cells 6. The juice flows for example from launder 15b at the discharge opening 16 into the cell 6b, Fig 2, and thence with the cossettes downwardly in 6b and upwardly in 6a and enters the launder 15c to be conveyed to cell 6d where it again flows downwardly with the cossettes and up into cell 6c whence it enters launder 15d. Thus extraction of sugar takes place in the concurrent flow and the juice is drained off and transferred by the launder to the next cell but two where extraction is repeated. The gases and vapours generated or released in the process fill the voids throughout the cells and so prevent exposure of the cossettes to air. The rates of flow of the conveyer and cossettes and the juice (by adjusting the pressure) may be varied.
