    Abstract: 937,473. Pressure relieving devices. BADISCHE ANILIN- & SODA-FABRIK A.G. Oct. 6, 1961 [Oct. 8, 1960], No. 35977/61. Class 135. A fluid pressure relief device comprises a concavo-convex disc 1 having its edge resting on a step of an annular ring 2 and preferably fixed by cement 4 such that the convex side forces the fluid pressure system to be controlled. A flexible foil 5, of precious metal or plastics, is clamped to the ring 2 on the convex side of the disc and is urged by fluid pressure against the disc. When a predetermined pressure is reached, the disc 1 flexes and becomes detached from the step and the foil ruptures, thus relieving the pressure and causing the disc to be blown out. The disc 1 may be provided with apertures so that the device may relieve in the opposite direction.

    Abstract: 890,986. Pulverulent fuel furnaces. BADISCHE ANILIN- & SODA-FABRIK A.G. Sept. 21, 1960 [Sept. 25, 1959], No. 32380/60. Class 51 (1). [Also in Group XIII] A fluidized bed reactor, particularly for the combustion of hard wet coal, is heated up by a flame 10 from an ignition chamber 6, 6 1 burning within the fluidized bed 5 of inert material, and granular material to be reacted is introduced into the fluidized bed immediately the flame is ignited. A long flame with approximately stoichiometric proportions of fuel and air is enclosed for part of its length in the ignition chamber, which may be inclined downwardly to prevent entry of the inert material. The ignition chamber opens below the surface of the fluidized bed. If a difficult substance is to be burnt, readily inflammable fuel such as brown coal is introduced to the bed immediately the flame is ignited, and the difficult substance is not introduced until the bed is heated to the ignition temperature of this fuel. The bed material may be sand, gravel, roasted ores or ash withdrawn from the fluidized bed during its previous operation.
