Abstract: Iron or steel products are produced from oxide ores in a unique process which utilizes air and regular coal as its primary energy source and wherein the ore is melted in a carbon dioxide zone for separation and absorption of the iron oxides into a slag which is transferred to a carbon-monoxide generating zone. In the latter zone the iron oxides are reduced to form the iron or steel product. Carbon monoxide containing flue gas from the latter zone is burned with air and utilized as a heat source in the carbon dioxide zone. Slag from the various unit processes is collected and used to preheat process air by either continuous operation or in a semi-continuous regeneration process. In both modes of slag preheating, flue gas is utilized to maintain the temperature of the slag bath and high temperature air preheating prior to the slag bath.

Abstract: A tool connects plugs to the ends of communication wires and in particular is used with modular type communication plugs.

The tool also has knives which can be used for stripping a specified length from the end of the outer sheath from the insulated wires before inserting the wires into a plug carried in a close fitting receptacle in one of the handle members. The punch has separated lands or bars that separately bear against each contact tang of the plug and in this way force the connecting tang into the individual communication wires.

Abstract: A very simple process is provided, with reduced processing time, for making a CMOS structure using a single polysilicon, or other refractory metal, layer which includes forming a thin gate oxide on both N and P type semiconductor layers of a common substrate, forming a gate electrode simultaneously on the N type and on the P type layers and selectively implanting an N type impurity to form N+ source and drain regions in the P type layer. The semiconductor layers are then oxidized to form substantially thicker oxide, such a silicon dioxide, adjacent to the sides of the gate electrode over the P type layer than the thickness of the oxide adjacent to the sides of the gate electrode over the N type layer. Without using a mask, a P type impurity is implanted into the N type layer to form P+ source and drain regions.

Abstract: In skylights wherein the wing may be selectively adjusted into a pivoting and swivel position, the wing is fixed with respect to the auxiliary frame in the pivoted opened position. If this fixation is removed due to a faulty operation, the upper, heavier half of the wing moves in the direction of the case so that there is a danger of damage. To make the negative effects of the faulty operation ineffective, flap 18 provided with latch 19 and having a pivoting axis displaced in relation to axial pin 7 in the direction of swivel joint 5 is pivotally mounted on auxiliary frame 2. Latch 19 arranged at a slight distance from axial pin 7 in the closed position subtends axial pin 7 when wing 3 is pivoted open. In case of a faulty operation, the weight of wing 3 causes axial pin 7 to be pressed against latch 19 of flap 18. This automatically secures a pivotally opened skylight against the results of a faulty operation, which is automatically undone, FIG. 4, when the wing is brought into the closed position.
