Title: Delivery-chute or charging apparatus more especially for charging carbonising retorts
IPC: C10B31/02
Filed: 1937-12-20
Abstract: 502,928. Shoots for charging carbonizing retorts. WOODALL - DUCKHAM (1920) Ltd., and VERITY, J. Dec. 20, 1937, No. 35204. [Class 78 (i)] [Also in Group XII] Apparatus for charging retorts is adapted, when brought into register with a storage hopper and the retort, to lower a charging shoot into the retort, swing a feed shoot above the charging shoot and open a pivoted door at the bottom of the feed shoot in timed relation with the swing. The apparatus, comprising a charging shoot 4, feed shoot 11, and hopper 13, runs on rails 3 so that it can be positioned between the overhead bunker 1 and the retort 2. During travel, the feed shoot 11 occupies the dotted line position clear of the charging shoot 4, and the latter is raised to its dotted line position clear of the retort. In charging the retort, the charging shoot is lowered into its upper end and the feed shoot swung about the pivot 12 until it is over the lowered charging shoot. The last stages of the movement of the feed shoot open the pivoted door 14 so that direct communication is established between the overhead bunker and the retort. Normally, the weight of the charging shoot is over-balanced by two superposed weights 6, 28 connected thereto by the ropes or chains 5. Rotation of the motor 20 drives the mutilate ' gear-wheel 21 counterclockwise. Initially, this drives wheel 22 until the weight 24 strikes the surface 25 and then it disengages. Finally, it drives the wheel 29 until weight 31 strikes the surface 32. The rotation of wheel 22 causes the cam 23 to raise the cord 26 and the upper weight 28, thus allowing the charging shoot to overbalance weight 6 and fall by gravity into the retort as the weights pass from the dotted to the full-line position. The rotation of wheel 29 operates chain gear 30 to rotate the crank arms 16, 17, thus operating the door 14 and swinging the shoot 11 in timed relation. Stops 33 and 8 fix the upper and lower positions of the shoot 4. When the flow of material ceases owing to all available space being filled, the door of the hopper 1 is closed and the motor is reversed. The driving of wheels 29 and 22 then closes the door 14, swings the shoot 11 aside and releases the weight 28 so that shoot 4 is raised from the retort. During this movement the contents of the shoot 4 are delivered to the retort forming a final upper layer above the level 35. This arrangement ensures filling to one predetermined level notwithstanding variation in the residual content of the retort before filling. In the Provisional Specification, the crank 17 and connecting rod 19 pass the dead centre of the shaft 15 in both extreme positions, thus retaining the shoot 11 automatically in register with the shoot 4 and in the " off position. Specification 357,146, [Group XII], is referred to.

Title: Improvements in or relating to the manufacture of ammoniacal copper cellulose solutions
IPC: C08B1/00
Filed: 1928-12-03
Abstract: 301,752. Hess, K., and Trogus, C. Dec. 3, 1927, [Convention date]. Ammoniacal - copper cellulose solutions.- Cellulose, for example cotton linters or bleached sulphite cellulose, to be used in the preparation of ammoniacal-copper cellulose solutions is pretreated in an ammoniacal copper solution containing caustic alkali, in which the proportion of copper present to cellulose treated is at least 1 : 2.6, until so much copper has been taken up by the cellulose that the product substantially comprises one atom of copper for every two molecules of cellulose (C6H10O5) and also contains caustic alkali. The pretreated cellulose will dissolve in very dilute ammoniacal copper solutions or in ammonia. solutions or even in water by virtue of the small amount of ammonia absorbed in the cellulose. The solutions used for the pretreatment may be ammoniacal copper solutions of any origin, e.g. ammoniacal copper sulphate, chloride, or oxide solutions and they may be used again after replacement of the copper but it is preferable to remove the salt, e.g. sodium sulphate, which has been formed, if this is present in excess. Specification 3566/06 is referred to.
