Title: Reinjection of blast furnace gas
IPC: C21B5/06
Filed: 1971-03-25
Abstract: Blast furnace mouth gases are treated to produce CO by dust removal, washing first in an aqs. sol. of ethanolamines + K2CO3 to extract CO2 and secondly in a conc. aqs. sol. of ammoniacal cuprous chloride + cupric chloride releasing a mixture which is optionally rewashed in cold H2O to condense the ammonia leaving pure CO. The CO is re-injected into the blast furnace and reduces consumption of coke.

Abstract: A small amt. of a first coloured glass is formed into a patterned lenticular shape within a mould. A second glass (colourless or different to the first) on the end of a blowpipe is adhered to the patterned surface of the first while it is still plastic, and roughly blow moulded into a cylindrical shape. A coating of a third glass (colourless is applied over the whole of the composite while still on the blowpipe, and the article finally blow moulded to the desired form. Spec. the patterns are indentations, and the air trapped therein by the second glass expands under its heat to form bubbles. Articles are produced more economically and with fewer rejects from imperfections.

Abstract: ABSTRACT OF THE DISCLOSURE    This invention relates to the toughening of glass sheets.  A glass sheet is heated and may be bent before being lowered into a chilling liquid to quench the sheet.          The leading edge of the sheet which contacts the chilling liquid first is hotter than the trailing edge of the sheet and preferably a linear temperature gradient exists up the sheet.  Glass sheets toughened by this method are used in the manufacture of motor vehicle and aircraft windscreens.

Abstract: Inventors:  Henry (NMN) Kressel Vikram Lalitchandra Dalal Title    :  SOLAR CELL DEVICE HAVING             IMPROVED EFFICIENCY                Abstract A body of semiconductor material in a solar cell device has a means for collecting electron-hole pairs with an incident surface through which solar radiation enters.           The collecting means can be a P N junction between two regions of opposite conductivity of the semiconductor body, or a partially transparent metallic film on the semiconductor body providing a metal to semiconductor material surface barrier rectifying junction.  On a surface opposite the incident surface of the collecting means is a non-continuous oxide layer.  The oxide layer is non-continuous because of openings extending through the oxide layer to the opposite surface.  The openings are distributed across the opposite surface.  In the openings at the opposite surface and on the oxide layer is a reflecting contact which functions both as an electrical contact and as a reflector to solar radiation in the semiconductor body.

Abstract: ABSTRACT OF THE DISCLOSURE A novel structural combination for use in gas discharge panels for generating alpha-numeric and video images which exhibit a high level of brightness, even in panels scanned in a point-at-a-time mode and at television scan rates.  The combination includes row-wise extending hollow cathodes comprising upper and lower metal cathode plates between which a hollow cathode discharge is generated.  The spacing between cathode plates is selected to insure that an efficient hollow cathode discharge is created. Situated forward of the hollow cathodes are a first electron-transmissive grid means for extracting electrons from the hollow cathode discharge, a second electron-transmissive grid means for controlling the flow of electrons through the first and second grid means, and a faceplate having a , hosphor coating thereon and adapted to receive an energizing potential for accelerating toward the phosphor coating those electrons which pass through the second grid means.  The faceplate and the second grid means are spaced apart by a distance which is too small to sustain a gas discharge at a gas pressure which exists in the panel.

Abstract: ABSTRACT       An internal combustion engine structure in which the cylinder head and main bearing caps are linked by a framework of members including pairs of tension members each angled obliquely to the direct line between head and caps.  The members of the framework are arranged so as to bear a substantial proportion of the firing loads of the engine in tension or compression without bending, thus relieving other parts of the engine, especially its outer surfaces, from loads under which they would tend to bend and thus emit noise.  The framework may also serve to strengthen parts of the engine wall to make it less susceptible to bending.

The proportioner mechanism is so assembled that it can be utilized as an original installation or as a replacement module.          In an installation where no proportioning action is required, the shuttle piston and head nut are installed without a proportioning valve.
