Abstract: Silicon platelets essentially free of iron are precipitated from a solution of metallurgical grade silicon in molten aluminum and are melted in contact with silica slag to produce a refined metallurgical silicon (RMS). Multigrained boules of said RMS may be pulled by the Czochralski method on a rotating silicon seed rod from a melt of said RMS. Alternatively, the silicon-slag melt can be directionally solidified to produce a directionally solidified refined metallurgical silicon (DS/RMS) separated from a region of solidified melt having a high concentration of impurities rejected by the silicon as it solidifies. Multigrained DS/RMS boules may be pulled from a melt of said DS/RMS. Alternatively, the DS/RMS is remelted and directionally solidified a second time with single crystal DS/RMS boules being pulled from a melt of the twice directionally solidified material. The thus-pulled multigrained RMS and DS/RMS and single crystal DS/RMS materials are low-cost products having a substantially higher impurity content than in conventional high purity semiconductor grade silicon while, at the same time, having desirable solar cell properties.

IPC: C10G9/28
Filed: 1979-11-13
Abstract: Heavy hydrocarbon-containing liquids are processed using apparatus comprising rotating inner and outer concentric tubes (11X, 12X). The inner tube (11X) provides a vapour zone and the annular space between the tubes provides a combustion zone. Hot particulate solids, such as sand, are advanced along an endless path through the vapour zone, back through the combustion zone and back into the vapour zone. In the vapour zone, oil is sprayed on the hot solids. The mixture is mixed and cascaded to obtain heat transfer from the solids to the oil, thereby generating hydrocarbon vapours and coke deposition on the solids. The vapours are removed by suction from the vapour zone. The coked solids are transferred into the combustion zone and cascaded and lifted and dropped therein to mix with added oxygen. Coke is burned to heat the solids which are then returned to the vapour zone. The vapours generated in the combustion zone are removed by suction. Segregation of the atmospheres in the two zones is achieved by a combination of maintaining equal pressures in the zones and using the solids, being transferred from one zone to the other, to block gas flow.

Abstract: In a device for measuring the breath volume of patients, a pair of temperature sensitive sensors are arranged in a tube-like housing of a respiration conduit of a respirator. The sensors are spaced from one another in flow direction and an air resistance member is arranged between them in such way that at least in one of the opposite air flow directions one of the sensors is in a position sheltered from the air flow by the air resistance member. Both of the sensors are connected with electronic circuits respectively and a current supply for holding the temperatures of the sensors on constant high levels. A calorimeter unit is connected to the circuits measuring the current supply necessary to compensate the temperature decrease of the sensors caused by the cool respiration flow. The air throughput is calculated in dependence on the measured current supply. Because in a predetermined flow direction the leeward sensor with respect to the air resistance member needs a lower current supply than the upstream sensor the calculating device provides different outputs for the pair of sensors whereby the flow direction can be determined and only the expiration air volume is indicated.
