Title: Pelletization of a sponge iron produced by direct reduction
IPC: C21B13/00
Filed: 1965-10-05
Abstract: <PICT:1123406/C6-C7/1> Fine-grained sponge iron such as that produced by reduction of ore in a rotary kiln is moistened and by means of a pelletizing plate or a granulating drum caused to roll upon itself whereby pellets are formed which are then hardened by heat-treatment at 500 DEG -1200 DEG C. The latter step may be carried out by returning the pellets to the fuel zone of the reduction kiln. In a preferred embodiment carbon, in the form of caking coal with or without other carbonaceous material, is incorporated in the pellets, while strength-increasing materials such as lime or bentonile may also be added, as may ore concentrates such as magnetite, or oxides of alloying elements such as nickel, manganese, chromium or vanadium. The resultant pellets may be charged to a steelmaking converter or other furnace. As illustrated sponge iron reduced in kiln 1 passes through cooler 2 to screen 7 where hardened pellets are discharged at 18. The fine material passing the screen is magnetically separated at 8, the metallic fraction being ground in grinder 10, and again magnetically separated at 11. The metallic product then passes by conveyer 12, where the desired additions are made, to mixer 13 and pelletiser 14, the product from which is returned to the final zone of the kiln by feeder 4.

The tang is raised between faceting operations by a single-acting pneumatic piston and cylinder 16, and its descent is controlled by a dashpot 18. The free end of the bar 2 carries a chuck 7, the inclination of which to the surface of a polishing wheel 9 is adjustable by a pivoted bracket II. The chuck is rotatable by a motor 20 about an axis passing through the centre of a gem held by a holder in the chuck and is movable by a motor 8 about an axis defined by a pivot 6 perpendicular to the bar. A suitable polishing direction for the first facet is established manually and the orbital position of the chuck manually set accordingly control section D activates reciprocation of the bar 2. Control sections A, B, C are then actuated. Polishing of the first facet continues until the gem holder contacts the polishing wheel, thus making a circuit through connections a, b, whereupon control section A activates the piston and cylinder 16 to raise the bar 2. When the bar is up, control section B activates the motor 20 for a set time to index the chuck for the next facet the motor 8 may be activated for a set time to index the chuck about pivot 6 to establish the correct polishing direction for this next facet as determined by the programming of section B. At the completion of indexing, control section C activates the piston and cylinder 16 to lower the bar. The cycle is automatically repeated until all the facets have been formed. A counting mechanism may then stop the machine or give a visible or audible signal.

IPC: H01L29/73
Filed: 1975-08-29
Abstract: An integrated transistor circuit arrangement provides a multicollector transistor with Schottky diodes and ohmic connections selectively formed at the collector terminals. In the illustrative example, a vertical transistor is formed in an N-type epitaxial layer overlying an N+ substrate. A through-extending region of P+ material encircles the region of the epitaxial layer in which the vertical transistor is formed. The base of the vertical transistor is formed by the implanting of P-type impurity in a location spaced apart from the surfaces of the epitaxial layer. The resulting base has a symmetrical profile relative to the faces of the epitaxial layer. Therefore, the transistor may be operated with the collector at the surface without penalty of electrical operation. In the illustrative example, a PNP lateral transistor is utilized as a current source for the vertical transistor.
