Abstract: ABSTRACT           A tube bundle heat exchanger having an additional tube bottom with insertion tubes arranged in the inlet chamber upon the inlet side of the hot gases for the tubes located between the tube bottoms and the tube bundle.  The additional tube bottom is arranged in such a way that both tube bottoms in the inlet chamber define another inlet chamber for colder, slag-free gases, which inlet chamber is accessible through an inlet in the shell of the tube bundle heat exchanger. The insertion tubes project far into, but not to the end of, the tubes of the tube bundle.  The insertion tubes, with the outer tubes, form relatively narrow annular spaces suitable for generating high discharge speed.  Four spiral-shaped strips respectively located in the annular spaces impart a twist to the gas flow discharging from the annular spaces to assure that gas discharging between the insertion tubes and the tubes of the tube bundle remain in flowing contact along the inner walls of the tubes.  Slag-containing gas coming from a coal gasification reactor flows through an inlet into the inlet chamber of the tube bundle heat ex-changer and is cooled off in three regions during flowing through the tube bundle heat exchanger whereby temperatures of the cooling-off gas are maintained in such a manner that slag is precluded from deposition upon the heat transfer surfaces while the gas is cooling off.

Abstract: ABSTRACT OF THE DISCLOSURE Cubic boron nitride has been made from powdered hexagonal boron nitride by a process which comprises vacuum firing of the HBN and conversion by high pressure-high temperature processing at 55-80 kilobars and 1600°C to the reconversion temperature.  This process may be carried out in a high pressure reaction cell having a special design which presents the entrance of impuritize into the sample. This cell, comprises, for example, a carbon tube enclosing concentric titanium sleeve.  Within the cylinder defined by the tube and sleeve are:  the HBN sample, carbon filler, shielding tantalum foil discs and carbon end plugs.  The vacuum firing is done at pressures of 10-5-10-10 mm ?, 1400 - 1900°C, for 5 minutes - 4 hours, and is believed to form a thin, free-boron coating on the HBN particles. The process works on both pyrolytic (turbostratic) and graphitic hexagonal boron nitride.  Grinding grits formed by milling cubic boron nitride chunks recovered from the high pressure-high temperature process have resulted in higher grinding ratios than commercially available CBN.

Abstract: ABSTRACT A process for the production of silicon or ferrosilicon by reduction of silicon oxide, optionally in the presence of iron or iron oxide, using a carbona-ceous reducing agent, in a reduction furnace.  The yield is improved without harmful temperature rises if the ratio of the amount of thermal energy supplied to the furnace to the amount of silicon oxide supplied to the furnace is made adjustable in such a manner that a value for the ratio can be set within an in-terval, which interval in its lower end is limited by the lowest value permitting constant reduction of the silicon monoxide and silicon directly with a proportion of the reducing agent which is supplied at the top of the furnace, because the amount of produced silicon monoxide is insufficient for complete conversion of all the carbonaceous reducing agent to silicon carbide at the top of the furnace, and in its upper end is limited by the highest value permitting constant reduction of the silicon oxide raw material to silicon monoxide and silicon directly with silicon carbide, because the amount of produced silicon monoxide is sufficient for conversion of the carbonaceous reducing agent to silicon carbide at the top of the furnace, and that n sufficient content of reducing agent is maintained inthe lower, hotter, parts of the furnace so that reduction to some extent can take place directly with the reducing agent.

Abstract: Apparatus for detecting faults in inherent flatness in a moving stretched strip, comprising a deflector roll in the form of a cylinder covered by a thin casing. Cavities are machined in the cylinder and arranged on a helix traced on the roll. Each cavity contains a displacement detector whose moving part in contact with the inner surface of the thin casing moves in the radial direction of the roll under the action of the stresses exerted by the sheet. The detectors have a primary winding and a secondary winding through which passes a core, solid with the moving part of the detector. The apparatus includes an optical encoding system for marking the angular position of the roll and a programming apparatus for sending a pulse of current to the primary windings of the detectors once under load and once not under load. A collector and processor for the emitted signals allow calculation of the values proportional to the tension in the strip, along its width. The invention may be used, for example, for monitoring the inherent flatness of thin, cold-rolled sheets.

Abstract: IMPROVED METHOD OF MAKING DIAMOND COMPACTS FOR ROCK DRILLING                     ABSTRACT OF THE DISCLOSURE        An improvement in the manufacture of diamond compacts is disclosed in which a cylindrical mass of polycrystalline diamond is surrounded by and bonded to an outer mass of metal which provides support for the diamond. The improvement comprises the use of seed diamond to grow the polycrystalline mass under high pressure-high temperature (HP/HT) conditions from non diamond carbon, utilizing a catalyst metal contained in the outer metal annulus. Preferably, this improved process is carried out using a cup-shaped metal mass having a stable carbide content of at least 10% and a coefficient of thermal expansion slightly higher than diamond. It is also preferred to heat the sample (the outer metal mass and the inner graphite mass) directly by passing an electric  current through the outer metal mass in the HP/HT process during which the polycrystalline compact is formed.
