Patent NO-853401-L (NO)
Inventor: CHEVROULET LEON
IPC: B30B15/14
Filed: 1985-08-29
Abstract: The continuous production of electrode material consisting of pitch, coke dust and coke particles of variable sizes comprising the steps of mixing and kneading the components in a horizontally arranged mixing and kneading device. An extruder is provided at the output end of the mixing and kneading device and connected with the same by way of a vertically arranged chute. The rotation of the extruder is controlled by a sensoring device provided in the vertically arranged chute. A lateral ejector orifice provided in the chute is shut off by means of an ejector flap subject to the influence of a control device; this in turn also exerts its influence on the extruder drive. The forming operation is completely separated from the mixing and kneading process, so that no mutual influencing can take place.

Abstract: There is disclosed herein a flat top and closure for a liquid carrying container, which includes two oppositely disposed, overlapped outer closure panels, and two oppositely disposed, three-segment fold-in panels, one of which serves as the pour spout when opened. Each of the three-segment fold-in panels includes a substantially triangular panel portion defined by converging diagonal score lines extending from the upper edge of the tubular container body, and a pair of fold-back panels integrally connected to and folded between the substantially triangular panel portion and the respective adjacent outer closure panels. Diagonal opening-assist score lines are formed on the outer closure panels. Abhesive patterns to facilitate the opening process are formed on the outside surface of the three-segment pour spout and on the inside surfaces of the pour spout fold-back panels and the adjacent panel segments bounded by the diagonal opening-assist score lines.
