Abstract: 771,715. Forced-flow steam boilers. SIEMENS-SCHUCKERTWERKE AKT.- GES. July 6, 1955 [July 12, 1954], No. 19527/55. Class 123(2) In a forced - flow once-through boiler comprising an economiser E, evaporating sections V<SP>1</SP>, V<SP>2</SP> and a superheater U wherein the regulators RK, RL,'RSP for the fuel, combustion air and feedwater respectively are adjusted by a device STLa in response to changes in boiler load, the device being controlled' by a pressure sensitive regulator RD which measures changes in the superheated steam outlet pressure P and wherein, to reduce the time lag between a change in load and the corresponding regulator adjustments, the feed water regulator RSP is also controlled to maintain a predetermined temperature at a point T in the boiler tube system, the coritrol temperature at T is adjusted according to the prevailing load on the boiler in a compensating device RT operatively connected to the load controlled device STLa as indicated by line ta. Thus for example, when the pressure P increases, the device STLa sets the regulators for a smaller load and the control temperature at T increases to allow for the fact that the evaporating zone is displaced towards the boiler inlet. If the temperature at T differs from the new control temperature, a supplementary adjustment of the feed regulator is then made.

Title: Method for producing dialkyl sulphoxides
Inventor: WETTERHOLM GUSTAV ALLAN
IPC: C07C317/00
Filed: 1952-08-07
Abstract: A method for producing dialkyl sulphoxides in high yields, e.g 90-95 per cent, comprises oxidizing the corresponding dialkyl sulphides in the liquid phase in the absence of water by means of oxygen or a gas mixture containing oxygen in the presence of one or more oxides of nitrogen selected from the group consisting of NO, NO2, N2O3, N2O4 as catalyst. Oxygen or air may be introduced into the liquid dialkyl sulphide together with one or more of the above catalysts which may be mixed with the oxydizing gas or added separately.  The process is preferably carried out in a closed system with circulation and reintroduction of part or the whole of the escaping gases which may also contain vaporized dialkyl sulphide.  Cooling may be employed if necessary.  The concentration of the catalyst is successively increased during the reaction and during the latter part the temperature may be raised slightly but should remain below the boiling point of the reaction mixture.  The reaction is preferably carried out in a reaction column filled e.g. with Raschig rings and provided with pipe coils for <PICT:0737575/IV (b)/1> <PICT:0737575/IV (b)/2> <PICT:0737575/IV (b)/3> <PICT:0737575/IV (b)/4> heating or cooling.  In the Figures, A or A1 and A2 represent the reaction column, B or B1 and B2 represent the pipe coils for the heating or cooling medium, D is the circulating pump, E and H the supply pipes for the oxidizing gases and dialkyl sulphide and I the piping for removing the dialkyl sulphoxide and piping E is combined with vessel C for supplying the catalytic gases.  In the arrangement shown in Fig. 1 oxygen is employed and partially saturated in C with the catalyst and the exit gas, chiefly nitric oxide, is recycled.  In the arrangement shown in Fig. 2 air is used and cooler F is necessary to reduce the amount of dialkyl sulphide carried along by gases passing off.  The apparatus in Figs. 3 and 4 may be employed for continuous operation, the reaction taking place mainly in A1 and being completed in A2 where fresh gas is introduced and heating applied.  In examples, dimethyl sulphoxide is obtained by reacting dimethyl sulphide and oxygen containing oxides of nitrogen in a column the lower half of which is filled with a filling material and the upper provided with a cooler (1); diethyl sulphoxide is obtained by reacting diethyl sulphide and a mixture of oxygen and nitric oxide in a glass tube, further nitric oxide being added during the reaction and cooling being applied, whilst the reaction product is neutralized with gaseous ammonia and distilled under vacuum (2).  Dipropyl, dibutyl and ethyl propyl sulphoxides are similarly prepared. Specification 645,268 is referred to.

Abstract: 1344476 Hydropneumatic buffers ALFRED TEVES GmbH 19 April 1971 [4 March 1970] 20166/71 Heading F2S A shock absorber, e.g. for use between a railway vehicle body and a bumper-baulk carrying the buffers and couplers, comprises a cylinder 1 in which a piston 3 normally rests at an end of its path, as shown, and defines one end of a variable chamber 15 from which liquid flow is regulated (e.g. by grooves 13 in a metering rod 4, over which passes the centrallyapertured piston 3, when the latter with its hollow piston-rod 2 enters the cylinder 1), if there is an impact to move the piston into the cylinder 1 from the end position through a shock-absorbing stroke; there is also a valve 10 responsive to the liquid pressure to open a passage 11, 6, 12 for the return of liquid to the chamber 15 (from a chamber 8 in the hollow rod 2) during a first part only of the return stroke of the piston 3 since the passage is ineffective for the latter part of that stroke (when the piston 3 is no longer positioned between cross-bores 9 and 11 in the metering rod 4 and the return stroke is retarded). In the piston-rod 2, a free piston 17 separates the liquid-receiving chamber 8 from a chamber 18 of gas under pressure so that a pressure is maintained in the chambers 8 and 15 and the annular piston 3 is biased to the rest position as shown. Pressure acquired, during a shock-absorbing stroke, by the gas in chamber 18, effects the return stroke. An impact on either end of the shock absorber moves the rod 2 and piston 3 into the cylinder 1 and liquid is displaced from chamber 15 through the parabolically-tapered grooves 13 to open pivoted flaps 14 therein and enter the chamber 8 and an annular space 20, which is enlarged by the movement of the piston 3. There are throttling bores 16 in the grooveclosing flaps 14 for the retarded return flow of liquid into chamber 15. Cross-bores 19 in the wall of rod 2, for communication from the space 20 when enlarged, are normally almost closed, as shown, by a conical surface of the cylinder wall so that the final movement of the piston 3 is gentle.
