Title: Improved process for the recovery of phosphorus and hydrogenated compounds thereof in the form of phosphoric acid
IPC: C01B25/20
Filed: 1927-04-20
Abstract: 269,908. Urbain Corporation. April 21, 1926, [Convention date]. Phosphoric acid.-Phosphorus or hydrogen compounds of phosphorus are treated to obtain a concentrated solution of phosphoric acid. The materials are burnt in a chamber 1 with air admitted through regulated openings. The products of combustion are passed up a Gaillard tower 2 down which phosphoric acid solution flows. The gases which enter the tower at a temperature about 900-1100‹ C. and escape at about 200-280‹ C., are passed through an immersed nest of tubes 5 in which they are cooled to 100-120‹ C. to avoid the condensation of steam, and into chambers 6 filled with coke in which combination of phosphorous pentoxide and water takes place. Water may be sprayed into the containers. A solution of phosphoric acid is obtained and is passed by a pipe 7 around the nest of tubes 5 where it undergoes a preliminary concentration and thence by a pump 3 down the tower 2 where it undergoes a final concentration.

[Also in Group II] Biscuits 10 are automatically converted from on-edge position to flat position by feeding the on-edge biscuits, e.g. on a supply conveyer A, to the entrance of an upwardly inclined channel 11, causing the biscuits to be pushed up the channel by the pressure of the biscuits behind, and allowing them to slide down a ramp 12 to a delivery conveyer 13. A stop 14 is preferably provided to cause the lower ends of the on-edge biscuits to move forwards on to the ramp 12 whereby the biscuits fall backwards into the flat position. Fig. 2 (not shown) shows the stop omitted whereby the biscuits fall forwards into the flat position.

Abstract: 1387061 Crystalline homopolymers B F GOODRICH CO 8 March 1972 [8 March 1971] 10752/72 Heading 3CP Crystalline homopolymers are prepared from monomeric olefins containing one double bond and from 5 to 12 carbon atoms or containing more than one double bond and from 4 to 12 carbon atoms by forming a liquid polymerization reaction medium comprising (1) a stereodirective Ziegler catalyst, (2) the liquid monoolefin which is a non-solvent for the desired crystalline homopolymer and (3) nucleating solid particles insoluble in the olefin, polymerizing the olefin in the absence of moisture, oxygen and solvent at a temperature from - 25‹ to 150‹ C. selected so as to be below the crystalline melting point of the desired crystalline homopolymer and below the decomposition temperature of the catalyst while subjecting the reaction mixture to a gentle continuous tumbling agitation employing a minimum of shearing forces on the reaction medium and wherein the polymer particles move randomly and gently with respect to each other and to the monomer in which they are suspended, the polymerization being continued for a time sufficient to convert the liquid monomeric olefin to the desired crystalline homopolymer in the form of substantially dry particles and recovering the dry particles. The nucleation particles may be particles of solid carrier for one of the catalyst components. In the examples butadiene, isoprene and 3 methylbutene-1 are polymerized using a mixture of VCl 3  on TiO 2 , TiCl 4  and tri-n-propyl aluminium; isoprene is polymerized using a mixture of VCl 3  on TiO 2 , tetraisopropyl titanate and triisobutyl aluminium or a mixture of VCl 3  with di-nbutyl ether and tri-n-propyl aluminium; and 2,3-dimethyl butadiene-1,3 is polymerized using TiCl 4  and tri-n-butyl aluminium.

Title: Improvements in the manufacture and production of carbamic acid chloride
IPC: C07C271/06
Filed: 1932-04-15
Abstract: Carbamic acid chloride is prepared by treating ammonium chloride with phosgene at a temperature between 150 and 340 DEG  C. The reaction may be effected by passing heated phosgene over agglomerated ammonium chloride, or by blowing phosgene and ammonium chloride together into a heated reaction vessel, or by blowing phosgene through a layer of ammonium chloride; the process may also be effected continuously. Carbamic acid chloride is separated from the reaction products by cooling, which may be effected in stages; residual gases containing phosgene may be returned to the process, if desired after removing hydrogen chloride.  The phosgene may be diluted with inert gases such as nitrogen, carbon monoxide, carbon dioxide, air and (or) hydrogen chloride.

Means for cleaning compressors having bladed rotors comprises a ring of pipes directed towards the compressor inlet, some of the pipes serving for spraying a solvent such as paraffin into the compressor, while the others serve for the introduction of pellets, preferably of lignin, into the compressor. Air under pressure is supplied through a pipe 5 to a container 3 to force solvent through a pipe 7 to an annular header 8 and thence through nozzle-ended tubes 9 directed towards the compressor inlet 1. The solvent is sucked into the compressor, which is running idly, and loosens the impurities deposited on the inner walls of the compressor. A valve 17 is then opened to admit air under pressure through a pipe 16, entraining pellets of lignin or the like by an ejector action from a container 12 into a pipe 13. The pellets pass by way of a header 14 to pipes 15, each disposed at its outlet end adjacent a tube 9. The pellets bombard the inner parts of the compressor to remove the deposits. Where the compressor forms part of a gas turbine engine, the pellets are consumed in the combustion chamber or are expelled through the turbine.
