Abstract: ABSTRACT OF THE DISCLOSURE         The invention is concerned with an improved method for the production of molten iron, which includes saturating a bath of iron contained in a vessel with carbon by injecting a carbon-carrier thereinto by means of an inert or reducing gas.  The improvement comprises forming a cone-shaped loose mass of iron ore upon the surface of the bath in an inner zone remote from the walls of the vessel, blowing oxygen onto the free surface of the bath in an outer zone adjacent the walls of the vessel and flushing an inert gas through the bath from the bottom thereof.  The invention also relates to an apparatus for carrying out this method, which comprises a metallurgical vessel for containing a bath of iron, having a cover provided with a feed conduit for charging iron ore onto the surface of the bath and forming thereupon a cone-shaped loose mass of iron ore in an inner zone remote from the walls of the vessel: at lea t one oxygen-lance extending through the cover for blowing oxygen onto the free surface of the bath in an outer zone adjacent the walls of the vessel; an injection-lance projecting into the vessel below the surface of the bath for injecting a carbon-carrier thereinto; and at least one nozzle-brick arranged in the bottom of the vessel for flushing an inert gas through the bath.  The invention enables one to effectively control the composition of the gases pro-duced when oxygen is blow onto the bath of iron which is saturated with carbon, by the simultaneous flushing with an inert gas.

Abstract: ABSTRACT OF THE DISCLOSURE           A digital data packet transmission system especially -but not exclusively- useful in videotex transmission uses a continuous transmission carrier.  Data packets are individually included in transmission blocks which are periodically transmitted, with dummy packets being used to fill the blocks, if necessary. The period of the transmission blocks are exactly equal or a little longer than the maximum length of the transmission blocks.  The beginning of each transmission block has a synchronization pattern which is constituted by a "bit sync" byte followed by a "byte sync" byte. The signals (except for the synchronizing pattern) are scrambled before transmission and descrambled upon receipt and recognization of the synchronizing pattern.

Title: Multi-gap high-voltage switch
Inventor: O'LEARY RAYMOND P
IPC: G03H1/04
Filed: 1981-08-17
Granted: 1983-12-27
Abstract: ABSTRACT OF THE DISCLOSURE A high-speed switch usable at high voltage includes a pair of contacts movable apart along a fixed line. When the contacts are normally interconnected, at least one of them contributes to the definition of an enclosed chamber. Pressurization of the chamber by the ignition of a power cartridge therein rapidly drives the contacts apart, forming a first gap between them. The first gap is electrically insulated and is shielded from the ignition products of the cartridge. Any arc forming in the first gap is constricted and subjected to arc-extinguishing gas. When the contacts are inter-connected, a first one of them is electrically connected to a terminal. As the contacts move apart, a second gap forms between the first contact and the terminal. The second gap is electrically insulated and is shielded from the ignition products of the cartridge. A fuse may be connected in shunt with the contacts and the insulated gaps. Preferaly, the shunt connection is made after the first gap is formed, but before the second gap is formed. This permits the first gap to effect commutation of current from the switch to the fuse and the second gap to be formed after the commutation. The second gap thus experiences no or only limited arcing and remains essentially uncontaminated so that recommutation of current from the fuse to the switch is prevented.

Abstract: REFERENCE VOLTAGE GENERATOR DEVICE            Abstract of the Disclosure The specification discloses a reference voltage generator device which detects a voltage corresponding to an energy gap of a semiconductor, or a voltage of a value close thereto, or a voltage based on an energy level of a semi-conductor, and generates the detected voltage as a reference voltage.  The reference voltage is generated by detecting the difference of threshold voltages of first and second insulated gate field-effect transistors (IGFETs).  Gate electrodes of the first and second IGFETs are formed on gate insulating films which are formed on different surface areas of an identical semiconductor substrate under substantially the same conditions.  The gate electrodes of the first and second IGFETs are respec-tively made of two semiconductors which are selected from among a semiconductor of a first conductivity type, a semiconductor of a second conductivity type and an intrinsic semiconductor made of an identical semi-conductor material, and which have Fermi energy levels of values different from each other.  The channels of the first and second IGFETs have an identical conductivity type.  On the basis of a self-alignment structure, at least those parts of first and second polycrystalline semiconductor regions being the gate electrodes of the first and second IGFETs which are proximiate to source and drain regions are doped with the same impurity as that of the source and drain regions, and a central part of one of the first and second polycrystalline semiconductor regions is doped with an impurity of a selected one of the first conductivity type and the second conductivity type.          The reference voltage is applicable to a differential amplifier circuit and operational amplifier of the offset type, a voltage comparator, a constant-current circuit, a voltage regulator, a Schmitt trigger circuit, an oscillation circuit, a battery checker, and so on.  In particular, the reference voltage generator device is relatively insensitive to changes of temperature.
