Title: Improvements in apparatus for intermittently inserting articles in to and withdrawing them from a sequence of solutions
IPC: G01N1/31
Filed: 1949-11-02
Abstract: Apparatus for intermittently inserting articles into and removing them from a sequence of solutions, particularly for the preparation of microscope specimens, comprises a basket to receive the article suspended from a plate above a series of receptacles containing the solution and arranged in a circle about a vertical shaft carrying the plate which is raised at predetermined intervals by the action of a master siphon fed with water from a constant pressure head, which siphon discharges into a second siphon chamber suspended by a cord passing over a pulley or pulleys and connected to the vertical shaft to raise the latter, weighted cords being provided to rotate the plate each time it is raised, the extent of rotation being such as to move the basket from one receptacle to the next, the emptying of the second siphon then permitting descent of the plate and the immersion of the basket in the next solution.  As shown in Fig. 1 the plate B bearing the basket A is supported by a vertical shaft C rotatably supported by ball bearings (not shown) on the top of a shaft C1 vertically movable in bearings c1.  A pulley c2 fixed to the bottom <PICT:0675880/III/1> of the shaft C1 is engaged by a cord e1 fixed at e3 and passing over a pulley e2 to engage the second siphon chamber E1.  The master siphon E is fed through a jet F to empty at predetermined intervals into the chamber E1 causing the latter to fall and by the cord e1 and pulley c2, to raise the basket from the container d.  To rotate the shaft C when it is raised it caries a bobbin G engaged by cords g1 passing over pulleys g2 to weights g which exert a couple on the bobbin.  Also connected to the bobbin is a rod H normally engaging one of a number of horizontal pins fixed to the bearing e1 thus preventing rotation by the weights g.  As the rod H rises its end passes the pins h and a projection h2 thereon engages and raises one of a number of pegs h1 vertically slidable in a member C2 fixed to the bearing c1.  This action allows rotation of the bobbin until the projection h2 engages the next peg h1 when rotation ceases.  On the siphon chamber E1 becoming full it discharges and allows the plate B to descend immersing the basket A in the succeeding container d.  One of the pins h is located higher than the remainder to limit rotation of the plate B to a complete revolution.

Title: Method of producing iron and other carbon binding metals and alloys thereof with a certain percentage of carbon directly out of oxide ore
IPC: C21B13/12
Filed: 1925-11-18
Abstract: 243,353. Flodin, H. G., and Gustafsson, E. G. T. Nov. 19, 1924, [Convention date]. Dry processes of extracting metals; briquetting- processes; alloys.-In a process for producing carbon binding metals and alloys thereof with a given percentage of carbon directly from oxide ores, a charge low in carbon, containing ore and carbon, and a charge richer in carbon, are mixed and the mixture treated in a furnace, preferably an electric furnace, the quantities of the two charges being so proportioned that a final product containing the desired amount of the carbon is obtained. The charges preferably consist of briquettes. When an electric furnace is used, the charge richer in carbon, which may consist wholly of carbon such as charcoal, peat, coke, or anthracite, may be fed directly into the furnace on to the slag bath formed in the reduction of the charge poor in carbon, and is fed into the furnace around the electrodes to prevent the slag corroding the latter. The materials, before briquetting, may be crushed finely and mixed with a suitable binding agent, and the briquettes &c. may be dried before feeding into the furnace. Before tapping the metal from the furnace, the metal may be deoxidized and recarburized by adding a mixture of finely divided oxide ore of a deoxidizing metal, e.g. manganese and finely divided carbon or carbonaceous material in sufficient quantity to deoxidize the said ore. In using sulphurous ore or carbon, lime-white is used as a binding agent for the briquettes &c., and when using phosphoric ore, a charge low in carbon is reduced, the whole or part of the slag removed, and then the reduction completed with the aid of a suitable amount of a charge rich in carbon. Specification 240,473 is referred to.
