Filed: 1923-01-03
Abstract: 193,007. Pastrnßk, A. Feb. 11, 1922, [Convention date]. Fuel, feeding; grates, cleaning; ash-pits.-A fuel feeding and distributing device for furnaces, serving also to remove ashes, clinker, &c. from the grate, comprises a reciprocating frame 8 carrying a fuel-receptacle 15, fed with fuel from a hopper 19 and automatically discharged at the front of the grate, and also pivoted blades 11 which move the fuel progressively forward, at the same time discharging the ashes, &c. into a removable receptacle 4 at the rear of the ash-pit. The frame 8 is reciprocated on a roller-track 9 carried by a frame 10, the frame 8 being moved slowly into the furnace and withdrawn quickly by a mechanically-operated chain 17. When the frame is at its innermost position, the blades 11, which are interconnected by a bar 12 so that they move simultaneously, are in the horizontal position indicated by dotted lines. When the frame reaches its outermost position, the receptacle 15 engages with a pin 23 on the counterweighted flap 20 of the hopper 19, which is thus opened to fill the receptacle. The latter is provided at the bottom with flaps 16 held closed, when the receptacle is at the front of the furnace, by a cam 24 on the frame 10. As the frame moves forwardly into the furnace, the flaps 16 are released and the fuel is deposited on the front of the grabe. The blades 11 remain in their raised position until the last blade passes the cam 24 when they are lowered to move the fuel forwardly a small distance and discharge ashes from the rear end of the grate into the receptacle 4. The latter is provided with a hinged bottom 6 and a front plate 7 serving as a scraper to remove ashes from the ash-pit while the receptacle is being withdrawn by the chain 5. The blades 11 are raised just at the end of their forward stroke by a counterweighted lever 13 attached to the bar 12 and operated by a cam.

Title: Process for the production of alpha-ethynyl-carbinols
IPC: C07C33/042
Filed: 1954-01-08
Abstract: An alpha-ethynyl carbinol of the general formula (R1) (R2) C(OH)­CH, wherein R1 and R2 are aliphatic hydrocarbon radicals or (R1)(R2)C is an alicyclic hydrocarbon radical is obtained by treating an aliphatic or alicyclic ketone with an alkali metal acetylide in the presence of acetylene and of an inert organic solvent at a temperature in the range 0 DEG  to 25 DEG  C. and under a gas pressure of 3 to 12 atmospheres in which the partial pressure of acetylene is between 2 and 8 atmospheres.  The alkali metal acetylide may be formed from acetylene and an alkali metal hydroxide, e.g. potassium hydroxide, preferably in the presence of an inert organic solvent at a temperature in the range 0-25 DEG  C. and under a gas pressure of from 3 to 12 atmospheres with the partial pressure of acetylene constituting more than 50 per cent of the total pressure and being in the range 2-8 atmospheres.  The acetylene both in the production of the alkali metal acetylide and in the reaction with the ketone is preferably diluted with an inert gas, e.g. nitrogen, with the partial pressure of the acetylene being more than 50 per cent of the total gas pressure.  The organic solvent with the alkali metal hydroxide in suspension is preferably saturated with acetylene before the ketone is added but it is also possible to add the ketone to a mixture of solvent and potassium hydroxide before the saturation with acetylene. The solvent employed is preferably an ether, e.g. di-isopropyl ether. In examples: (1) a suspension of pulverulent potassium hydroxide in dry isopropyl ether in an autoclave filled with nitrogen at 3.5 atmospheres is saturated with acetylene, the total gas pressure being 8 atmospheres, and a solution of methyl ethyl ketone in di-isopropyl ether is then forced in under nitrogen pressure and acetylene is forced in to give a total gas pressure of 8 atmospheres, the pasty reaction mixture formed is then decomposed with water and the ether layer worked up to yield 3-methylpent-1-yn-3-ol; (2) 3-methyl-but-1-yn-3-ol is obtained from acetone by a process similar to that used in (1); (3) 1-ethynyl-cyclohexanol is obtained from cyclohexanone by a procedure similar to that used in (1); (4) a mixture of pulverulent potassium hydroxide, di-isopropyl ether and methyl ethyl ketone in an autoclave purged with nitrogen and cooled with ice is treated with acetylene to give a total pressure of 8 atmospheres of which the partial pressure nitrogen is 2 atmospheres and the process is continued until no further reduction in pressure occurs.  The product is then treated for the recovery of 3-methyl-pent-1-yn-3-ol.
