Title: Method of producing hydrogen by converting carbon monoxide with steam
IPC: C01B3/16
Filed: 1945-08-28
Abstract: Hydrogen is produced by converting carbon monoxide or gaseous mixtures containing carbon monoxide with steam using a catalyst as described in Specification 601,535.  The process is carried out as described in Specification 464,667, preferred operating conditions being a pressure of 5-10 atmospheres, a temperature of 350-500 DEG C., and a steam to carbon monoxide ratio of 4 to 1.  Two catalyst chambers may be used between which additional steam is introduced. By using the catalysts below the dissociation temperature and pressure of the hydroxide present, formation of the oxide is avoided, and this prevents disintegration and loss of activity of the catalyst mass.  Specifications 355,861 and 417,829 also are referred to.

A cord 20, secured to the drum 15, passes round the drum and a series of guide pulleys 19 attached to the front plate, to form two vertical spans carrying index bars 22 which co-operate with the scales 25. The fine tuning indicator comprises two discs 26 and 27, Figs. 3 and 4, concentrically mounted at point 28 on the front plate, disc 26 being stationary and disc 27 rotated by cord 20. Disc 26 is provided with eighteen radial slits 29, and nineteen radial slits 30, while disc 27 has nineteen slits 31 and a slot 32, a light source being arranged behind the discs. The discs are arranged so that as the light is being extinguished passing through one pair of slits 29, 31, it is just appearing in the next pair of slits, and while all the slits 29, 31 are brought into register in turn, the same slit 30 remains illuminated through slot 32.

Apparatus for stamping out and separating portions from a web 9 of, e.g., plastics material, comprises a stamping-removing tool 20 adapted to penetrate the stamping during the stamping stroke of a punching tool 11, the tool returning by way of a stripper plate 21 on the return stroke of the punching tool so that the stamping is transferred to a collecting receptacle 33. The tool 20 is mounted on a bar 19 which is connected to a lever 17 pivoted on a pin 16. In operation, the tool 11 is lowered by a rod 27 thereby causing the tool to penetrate the web 9. At the same time the tool 20 is raised by means of pins 24 on the rod 27 engaging the lever 17. The centre of the stamping is supported by a member 13 so that the pointed end of the tool pierces the stamping which, when the bar 19 is lowered, is pulled through a cutting pad 8 by means of a hook 34 on the tool; further downward movement of the tool causes the stamping to be stripped off the tool by a plate 21 so that the stamping can fall into the receptacle 33.

Abstract: 1499685 Removing monomeric impurities from a vinyl chloride polymer dispersion CHEMISCHE WERKE HULS AG 23 May 1975 [27 Aug 1974] 22562/75 Heading C3P A process for removing monomeric impurities from an aqueous dispersion of a vinyl chloride polymer having a surface tension of less than 60 dyne/cm., comprises mixing the dispersion continuously with steam in a flow tube, the flow speed of the mixture in the flow tube being 1-20 m./sec. and the pressure in the flow tube being 150-600 mmHg, passing the steam/ dispersion mixture which issues from the flow tube directly to the upper part of an evacuated vessel in which the pressure is 30-200 mmHg lower than the pressure in the flow tube, the mixture issuing from the flow tube at a speed of 30-100 m./sec., and continuously withdrawing the dispersion from the degassing vessel. The average residence time of the dispersion in the degassing vessel is 2 mins. to 4 hours. The weight ratio of steam to dispersion may be 1 : 5 to 1 : 100 and the temperature in the tube may vary from 60 to 94 C. It is preferred to allow the dispersion/steam mixture to enter the degassing vessel from the flow tube tangentially to the wall of the degassing vessel or to brake the liquid jet on baffle plates arranged at shallow angles. Alternatively, as shown in the Figure, a flow tube (FT) may be used terminating in a Feld's nozzle which extends into a degassing vessel (D). The flow tube has connections for the dispersion (Di) and the steam (St) and the degassing vessel has an outlet (O) and a level regulator (L) in order to maintain a certain level in the vessel.
