Title: Method of and apparatus for the incineration of refuse and similar waste materials
IPC: F23J1/00
Filed: 1928-10-29
Abstract: 323,841. Uhde, O. Oct. 29, 1928. Blast apparatus; grates.-In a refuse-consuming furnace 2, the refuse is supplied so that it piles up against the walls and blast is intermittently supplied through the main grate 3 and auxiliary side grates 4 to effect combustion and also to carry away the fine difficulty combustible particles into a dust chamber where they are burnt. The clinker is removed from the grate 3 at short time intervals through flap doors 20 by an hydraulically-operated ram 7, Fig. 2, which, in the position of rest, forms a part of the furnace wall. The ram 7 is cooled, during its forward and backward movement by the high-pressure water used to operate it, a separate low-pressure supply for cooling being automatically brought into operation when the ram reaches the position of rest. The ram-head 7 is carried by a cylinder 6 which is slidable over a fixed hollow piston-rod 8, piston 9 and block 10 and is fitted with a stuffing-box 25 at its rear end. To prevent distortion and jamming due to expansion of the furnace structure, the cylinder 6 is mounted by means of guides 15 and trunnions 23 in a frame 13 which is supported at its near end on trunnions 26 and adjustably secured at its forward end to a member 18 serving to guide the cylinder in the furnace framework 24. Fig. 2 shows the position when a controlling-handle 40, which is connected to pistons 28 - - 34 in regulating cylinders 16, 17, is moved to effect forward motion of the ram. The high-pressure water travels along the path 35, through pipe 43, hollow rod 8, and port 21 to the space 36, the water behind the piston 9 escaping as the ram moves forwardly, through pipe 11 and along path 37 to the waste funnel 38. Since the space 36 is open to the hollow ram-head 7, the actuating water also effects the cooling, the lowpressure water 39 simply passing through the cylinder 16 to waste. In Fig. 3 the handle 40 is shown in position for returning the ram, the highpressure water 41, in this case, traversing the path 37 and passing through pipe 11 into the space between the rod 8 and cylinder 6; exhaust trom the space 36 is effected through port 21, hollow rod 8, pipe 43 and path 44. The low pressure water traverses the path 45, pipe 12, and port 22, so that when the ram reaches its normal position, the circuit for the low pressure cooling water is again established.

Title: Preparation of octaalkylpyrophosphoramides
IPC: C07F9/24
Filed: 1955-11-04
Abstract: An octaalkylpyrophosphoramide having 1 to 4 carbon atoms in each alkyl group is obtained by reacting a tetraalkyldiamidochlorophosphate with an anhydrous alkali metal carbonate at a temperature between 50 DEG  and 250 DEG  C., the carbonate being present in an amount of at least one mol. for each two mols. of the tetraalkyldiamidochlorophosphate, and recovering the octalkylpyrophosphoramide from the reaction mixture.  The reaction may be carried out in the presence of an inert volatile organic solvent, e.g. a high boiling aliphatic ether such as dibutyl-, dihexyl-, or dioctyl ether, a hydrocarbon such as octane, nonane, toluene or xylene, or a chlorinated hydrocarbon, e.g. hexyl chloride, octyl chloride, or propylene dichloride.  The alkali metal carbonate may be sodium, potassium, or lithium carbonate.  Specified reaction temperatures are 50 DEG  to 250 DEG  C. and preferably between 80 DEG and 125 DEG  C.  The reaction is complete when the evolution of carbon dioxide ceases and the mixture is then filtered and the filtrate stripped (if a solvent is used in the preparation) and the residual octaalkylpyrophosphoramide recovered as an almost colourless liquid.  Examples are given for the production of octamethylpyrophosphoramide using tetramethyldiamidochlorophosphate and anhydrous sodium carbonate and it is stated that octaethyl- and octabutylpyrophosphoramides can be obtained in a similar manner from the appropriate tetraalkyldiamidochlorophosphates and anhydrous sodium carbonate.
