Patent GB-289079-A (GB)
IPC: F23N1/02
Filed: 1928-03-07
Abstract: 289,079. Siemens & Halske Akt.- Ges. April 23, 1927, [Convention date]. Addition to 281,312. Regulating combustion.- In means for regulating combustion in boiler furnaces in which a rotating piston of a piston manometer connected to the main steam pipe adjusts two electrical resistances in regulating circuits which control the draught and. fuel supply as described in the parent Specification, one of the resistances lies in a regulating circuit working with a linear characteristic and the other, preferably that for the regulation of the draught, lies in a regulating circuit with a quadratic characteristic and means are provided for enabling these circuits to be readily adjusted in accordance with the load. The steam pressure of the boiler actuates a rotating piston 2 and shaft 5 to vary a resistance 6 in one arm of a Wheatstone bridge. A relay 10 in the diagonal of the bridge allows current to pass to the motor 16 and move it in one direction or the other to operate the air supply valve 17. Balance is restored in the bridge by the pressure in the air supply pipe 20 actuating the device 18 to vary the resistance 21 in another arm of the bridge. Bridge resistances 42, 43 in different branches thereof and graduated in values increasing quadratically are varied by a hand-actuated member 44 according to the desired load on the boiler. The piston 2 also serves to vary a resistance 24 in the fuel supply circuit and vary the potential produced by a battery at a galvanometer relay 29 in opposition to that produced by a dynamo 37, in circuit with a potentiometer, driven by the motor 34 for driving a travelling grate. Variation of the resistance 24 produces a variation of the speed of the dynamo until a balance is restored on the potentiometer.

Abstract: Compounds of the general formula <FORM:0981213/C2/1> in which R1 is a hydrogen atom or an alkyl, aralkyl, or cycloalkyl group and R2 is an alkyl, aralkyl or cycloalkyl group are obtained by subjecting a compound of the general formula <FORM:0981213/C2/2> wherein R1 and R2 are as defined above to isomerization by heating and recovering the isomerized product. The heating is preferably effected at between 120 DEG  and 200 DEG  C. The invention also includes as new products compounds of the first given general formula above but excluding those in which both R1 and R2 are alkyl groups.  Examples are given for the production of compounds of the first-given general formula above in which (1) R1 and R2 are ethyl, (2) each R1 is hydrogen and R2 is benzyl, and (3) R1 and R2 are benzyl.  The product in which each R1 is hydrogen and each R2 is benzyl is obtained in the example by adding an ethereal solution of trimeric phosphonitrilic chloride to a solution of sodium in benzyl alcohol at 0 DEG  C., filtering, diluting with ether, and washing the extract with dilute aqueous solutions of HCl, sodium bicarbonate and water.  The starting material of the second general formula above in which R1 and R2 are each ethyl is obtained by dissolving trimeric phosphonitrilic chloride in pyridine, stirring and cooling the solution and adding ethanol slowly while maintaining the temperature at 0 DEG  to 5 DEG C. The starting material in which R1 and R2 are each benzyl is obtained by refluxing dry benzyl alcohol with a solution of sodium in dry ethanol in a column until the ethanol is removed, replacing the ethanol by dry dioxane and adding a benzene solution of trimeric phosphonitrilic chloride to the refluxing alkoxide.

Heading B1B. Liquid is evaporated in the form of a downflowinig film on the heated internal surface of a vertical body 1 within which is mounted a shaft 2 supporting rotatable hollow drums 9 the walls of which have longitudinal projections with holes 14 from which the liquid-to-be-evaporated is distributed from inside the rotating drums onto the internal surface of the body 1. The middle part of the evaporator shown has three sections 6 each having an external heating jacket and a liquid-distributing drum 9. The drums are fastened to shaft 2 by rings 11 and 12. The feed liquid is introduced into the evaporator through pipe 50 and is thrown, by centrifugal force from radial tubes of a sleeve attached to rotating shaft 2, onto the internal surface of a stationary cylinder, the lower edge of which has teeth for distributing the liquid onto the upper ring 11 of the uppermost drum 9. The liquid is then thrown by centrifugal force onto the internal corrugated surface of the drum and is distributed by the projections into individual vertical streams, the liquid then being thrown through holes 14 onto the heated internal surface of the uppermost section 6 of the evaporator, where the liquid forms a downflowing film from which partial evaporation takes place. The non-evaporated liquid flows into a collector, between the two upper sections 6, whence the liquid flows along chutes 29 onto the internal surface of the drum 9 of the second section 6, where the process of liquid-distribution and partial evaporation is repeated. The same applies in the lowest section 6. Residual liquid is discharged from the evaporator through pipe 51. The vapours ascend through the gaps between the body 1 and the drums 9 as well as through the drums into which the vapours penetrate through holes 35 in the hollows of the corrugations. The vapours reaching the top of the evaporator pass through a droplet-separator, and are discharged through pipe 52.
