Patent GB-268839-A (GB)
Abstract: 268,839. National Cash Register Co., (Assignees of Shipley, B. M.). July 9, 1925, [Convention date]. Adding and subtracting apparatus with printing-mechanism; differential-mechanism; columnspacing.-In a machine such as that described in Specification 255,076 wherein the printing of figures set up is effected in different columns under control of the keys, the selection of the columns is performed by the differential-mechanism of the first control bank under the control of the keys in this bank and in the other two control banks. The control of this differential mechanism is readily variable to adapt the invention to different systems of accounting &c. The column-selection is effected through the printing- hammers by means of the differential 115, Fig. of the first control bank containing the two keys 70, 71, Fig. 2. In the arrangement described printing may take place in one of four columns according as the differential latch 102 is broken in the 9, 0, 7 or 8, or the 2 or 5 position. When a key in the third bank is depressed an arcuate detent plate is displaced to retract the zero trip pawl 65 to enable the latch to travel to position 9 before breaking and thus to produce a print in the first column. When one of the first eight keys in the second bank is used, no interference with the first bank differential ,takes place and consequently this stops in the zero position and produces a print in the second column. The ninth key in the second bank however when depressed rocks a lever 380 linked to a lever 382 the end 389 of which is thus caused to enter the path of a stud 388 inserted in a chosen one of a number of holes in a plate 378 rigid with the latch-controlling arm 376 of the first bank. This mechanism breaks the latch in position 7 and printing takes place in the third column. The zero trip pawl is removed by a pitman 397 held by a spring in engagement with the yoke 384 rigid with lever 382. The third column may also be selected by depression of the " correction " key 70 the stem of which breaks the latch in the usual manner in the 8 position. An impression in the fourth column occurs when the key 71 occupying position 2 is used, and also when a total is taken. In this latter case, the total lever 80 when moved one step up or down from adding position rocks a lever 415 to bring a lug 414 into the path of a shoulder 416 in a second plate 378 rigid with the latch-controlling arm 376. This breaks the latch in position 5. If the total lever is moved more than one step, lever 415 rocks counterclockwise to bring a nose 420 into the path of a shoulder 422 to break the latch also in position 5. In total-taking operations the zero trip pawl 65 is removed by the usual mechanism. Specifications 8119/15, 199,046, 215,749; 221,823, [Class 83 (iii), Metals, Cutting], and 223,939 are referred to.

Title: Improvements in or relating to apparatus for the treatment of molten material
IPC: B28B1/54
Filed: 1934-09-25
Abstract: 444,699. Treating slag &c. BENZINGER, W., 31, H³ttenstrasse, D³sseldorf, Germany. Sept. 25, 1934, No. 27542. [Class 22] Apparatus for the treatment of molten material, especially for the production of " foam slag " or artificial pumice produced by the action of water upon molten slag, comprises a tilting ladle, having a number of compartments, arranged to tilt about the axis of a hollow shaft through which is introduced fluid for treatment of the molten material. Preferably the tilting movement automatically controls the admission of fluid to the ladle. When treating slag, sulphur, phosphorous and the impurities are preferably removed before the slag is foamed, the slag being first treated in a ladle through which appropriate gas is passed and then deposited in another ladle through which the water for the foaming operation is driven. In the arrangement shown in Fig. 1, two ladles 1, 2 having hollow shafts 4, 4<1> are geared together by toothed sectors 6, 6<1> so that they tilt in opposite directions, the slag being first treated in the top ladle and then deposited into the under ladle. Piston-operated mechanism 8, 10 is provided for tilting the ladles, and the upper ladle is provided with a counter-balance weight 12. The hollow shafts have perforated walls and are divided interiorly into a number of compartments by radial partitions. The ladles also are formed with hollow walls perforated at 15. At one or both ends of each shaft are a number of supply inlets which mav be so arranged that the distribution of fluid is effected automatically by the tilting of the ladle. The shafts are perforated so that fluid is supplied to the hollow walls of the ladle and is also sprayed through the perforations in the under side of the shaft on to the slag below. In a modification, two ladles work together but tilt in the same direction and deal with different changes of material. In another modification, Fig. 3, the ladle has two smaller compartments on the lower side, so that by reversing the ladle its capacity is altered. The walls 14 are not perforated but are intended to receive cooling fluid from the hollow shaft 8 by perforations 40.
