Title: Improvements in or relating to the production of cement clinker
IPC: F27B1/00
Filed: 1960-07-18
Abstract: <PICT:0959446/C1/1> A process for the production of cement clinker comprises feeding powdered raw material into an ascending hot gas stream where it is sintered, the gas velocity being sufficient to suspend the powder until sintering is complete, whereupon the feed of raw material is interrupted and the gas stream is throttled to allow the sintered clinker to fall into a quenching medium.  As shown in Fig. 1, the raw material which may be preheated is fed into a vertical shaft furnace via a calcining and preheating section 6, a regulating cone 7 allowing an intermittent feed into the sintering zone 5. Secondary combustion air is introduced at 2, primary air at inlets 4 and fuel at 3.  The shaft is constricted at 8 above the inlets 4 and the diameter increases towards the calcining zone so that the gas velocity decreases in this zone.  On completion of the sintering the powder feed is interrupted by cone 7, the gas is cut off the sintered material falls into the quenching medium 1 which may be water, air or nitrogen. In a further embodiment (Fig. 2, not shown), the calcining and sintering zones are separated by a further constriction in the shaft while Fig. 3 (not shown) incorporates a combined upper and lower vertical shaft offset from each other.

Abstract: 337,862. Hartung, C. A. Aug. 21, 1929. Gas analysis.-In automatic gas analysis apparatus in which a gas is added to the gas to be tested and the mixture then brought to reaction e.g. in the determination of residual oxygen in flue gases by the addition of hydrogen, the reaction chamber is provided with a bye-pass tube to prevent explosions when the analysis is started, and to facilitate the setting of the zero-print. In the apparatus shown, the gas to be tested is drawn in from a previous analysis. On the upward stroke k to reservoir h by lowering a vessel d which acts as a pump. At the same time, the pipe r is opened and bell s falls, thus expelling the gases from a to the reservoir c, and hydrogen through of d, the gases in c and h are forced into the mixing vessel n and thence through the reaction vessel q, preferably containing a contact substance, to the bell s where the increase or decrease of volume is measured in Imown manner. During the first analysis, the reaction chamber q is cut off by cock p and the gases passed directly through t to the bell, thus preventing explosions due to the presence of air mixed with the hydrogen in h, and also enabling the zero-point to be set. It is preferable also to warm the bye-pass t in order to avoid errors due to temperature when making comparative tests.

To eliminate stray light reaching an observer's eye by reflection from a ground-glass focusing screen or the like, a curved coloured disc is placed between the screen and the observer's eye with its concave side towards the observer's eye which is placed substantially at the centre of curvature so that it is imaged on itself. Light incident on the disc 5 will necessarily originate from points such as 6 other than the region of centre of curvature so that no reflected light can enter the eye. Stray light passing through the disc and reflected from the screen 1, or a magnifier 2 in front of it, will pass twice through the disc, and will thus be greatly attenuated, before reaching the observer's eye. Preferably, also, the magnifier has an anti-reflection coating giving maximum suppression for the wavelength region where the disc transmits.
