Abstract

101,156. Margreth, J. Aug. 12, 1915, [Convention date]. Regulating head of liquid directly; solid in separate charges in generator. - The generating- chamber of an acetylene-generator consists of two concentric bells, the inner one containing the carbide vessel and serving for the generation of the gas, while the outer bell collects the " after gas " and leads it to the gas-bell; each bell communicates by a tube with the gas-bell, and the generating and gas bells are immersed in a common water tank. The generating-chamber may be rigidly but removably connected with the gas-bell. In the construction shown in Fig. 1, the annular gas-bell d surrounds the double generator-bell a, b, and is immersed in a water tank f; the inner bell a contains the carbide vessel and gas generated passes by a pipe g to the gas-bell d. When the cock h is closed, the after gas forces the water out of the bell a and escapes by the lower edge i to the bell b and thence by pipes k, l to the gas-bell. The pipes g, k, l form a rigid coupling between the bells a, b and the gas-bell; a screw-coupling m allows removal of the bells a, b. Gas for consumption is led off by the cock o. In modified constructions, the double generator-bell is immersed in the water tank at the side of the gas-bell and connected therewith by a flexible pipe, the rigid coupling being effected by a lug extending upwards from the bell band passing through and clamped to a slot in a projection extending from the gas-bell. Specification 9373/14 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a further modification, Fig. 4 (Cancelled), in which the inner and outer bells a, b are connected by a pipe l, the and opening into bell b being at a lower level than the top of the carbide-container w; the carbide is placed on a series of horizontal trays t<1> - - t<5> of semi-cylindrical cross-section; water enters by an opening v and passes under a partition x to the bottom of the carbide-container. This subject-matter does not appear in the Specification as accepted.
