Title: Glass furnace having electrically heated submerged throat and method of operation
Inventor: MADDUX JOHN F
IPC: C03B5/027
Filed: 1975-07-14
Granted: 1980-01-29
Abstract: ABSTRACT OF THE DISCLOSURE         Arrangement for and methods of operating electrically heating a submerged throat between a glass melter and a final conditioning zone enable the pull rate of glass to be reduced while maintaining temperature control and to be stopped without freezing the molten glass in the throat, which has its walls exposed to the ambient temperature.  High rates of heat loss in the throat region are compensated for with a high voltage power supply to electrodes positioned for Joule effect heating of the glass in the throat.  Thermal adjustment at maximum pull rates is enhanced by the use of cooled electrodes in the throat as heat extractors with no electrical energy supplied.  Low or zero pull rates can be tolerated without throat freeze-up by connecting additional voltage sources in series with the supply to the throat electrode.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a method of harvesting tobacco and system for bulk handling whole leaf flue cured tobacco between field harvesting and curing and drying operations.  In the method of harvesting tobacco, tobacco leaves are defoliated from tobacco stalks and conveyed therefrom to an area of discharge where the leaves are discharged and directed in random alignment into an open top bulk tobacco support unit such that the randomly aligned leaves are generally uniformly distributed within a bulk support unit and the tobacco leaves are generally disposed in horizontal planes with the individual leaves being disposed in overlying relationship. After the bulk support unit has been filled to a predetermined level, a plurality of elongated members are inserted through the bulk support unit in directions gener-ally perpendicularly to the planes of the tobacco leaves.  There-after, the filled bulk support unit is rotated approximately 90 degrees such that the planes of the leaves within the bulk support unit are rotated from generally horizontal positions to generally vertical positions and wherein said bulk support unit includes a continuous volume of leaves with the depth of the volume being greater than the length of the respective leaves comprising the volume.  After rotation, the bulk support unit is transferred into operative relationship with a curing and drying system, the bulk support unit being positioned such that the planes of the leaves are generally vertically oriented so as to enable a forced system of air normally associated with a curing and drying system to readily move therethrough.           Basically the apparatus or bulk handling unit supporting the harvested tobacco comprises a rectangular frame structure that when disposed in the filling position includes a leaf receiving area of substantial cross sectional area, both the length and width of the cross sectional area being greater than the length of the respective leaves received within the bulk support unit.  For con-fining the volume of tobacco within the bulk handling or support unit, there is provided a plurality of tines that are adapted to project through the bulk support unit and to support portions of the volume of bulk tobacco within the unit when the support unit is rotated approximately 90 degrees from the horizontal filling position to a vertical position.  Therefore, it is appre-ciated that once rotated, because of the substantial cross sectional filling area, that the vertical depth of the bulk support unit is greater than the length of the respective leaves comprising the volume.

Abstract: ABSTRACT OF THE DISCLOSURE   Apparatus is provided comprising two drying towers, each having upper and lower ends respectively and including a drying agent for drying compressed gas (e.g., compressed air) that is caused to flow through the drying towers alternately.  A minor quantity of the dried gas (e.g., air) expelled from one of the towers is fed back into the other tower for drying the drying agent therein.  The feedback element in each tower is an elongate hollow cartridge, through which the minor quantity of dried air flows and thereafter is conveyed to outside the drying agent, subsequently penetrating the latter and being discharged at the end opposite to that at which it has been introduced.  A pair of perforated plates may be located in each tower for enclosing the drying agent between them to create a homogeneous flow of the compressed gas or compressed air to be dried.  The elongated hollow cartridges may  to advantage be located approximately centrally in the respective towers.  The structure provides more economical operation with minimized loss of heat.

Title: Process for the exchange of hydrogen isotopes between streams of gaseous hydrogen and liquid water and catalyst
Inventor: BUTLER JOHN P
IPC: C01B4/00
Filed: 1976-06-25
Granted: 1979-10-02
Abstract: ABSTRACT OF DISCLOSURE A process and catalyst for the exchange of hydrogen isotopes between streams of gaseous hydrogen and liquid water is described, wherein the streams are brought into contact with one another and a catalyst assembly at a temperature in the range 273 to 573K, the catalyst assembly comprises an inherently hydrophobic, porous, polytetrafluoroethylene matrix and partially platini-zed carbon particles in the weight ratio of 0.5:1 to 6:1 of polytetrafluoroethylene to partially platinized high surface area carbon particles.  The inherently hydrophobic, porous polytetrafluoroethylene matrix allows the catalytically acti-ve metal to catalyze the hydrogen isotope exchange reaction between hydrogen gas and water vapour in the presence of li-quid water while retarding loss of activity of the catalyti-cally active metal by contact of the metal catalyst with li-quid water.  This catalyzed chemical isotope exchange proceeds simultaneously with isotope exchange from water vapour to li-quid water by a non-catalyzed, physical evaporation and con-densation exchange reaction.  The efficient coupling of the two isotopic transfer steps which results in a rapid overall isotopic exchange between hydrogen and liquid water without a pronounced loss of activity of the catalyst is dependent upon the weight ratio of the catalytically active platinized carbon to the polytetrafluoroethylene matrix being in the range 0.5:1 to 6:1 and for best results preferably in the range 1:1 to 3:1.

Abstract: DATA STORAGE APPARATUS        Abstract Data track position information for data tracks on a stack of recordingdisks is provided by servo information pre-recorded on one surface of the stack.  In addition, each data track on the remaining surfaces of the stack has servo information relative to that track pre-recorded in sectors around the track.  Track access operations are controlled using track crossing information derived from the pre-recorded servo information on the servo surface and track following operations are controlled in a closed loop servo system using on-track position information derived from the sectored servo tracks associated with the track being followed. The band-width of the position error signal derived from the sectored servo infor-mation is increased by adding high frequency components obtained from the continuous servo information on the servo surface.

Abstract: ABSTRACT OF THE DISCLOSURE Well logging depth measurement method and system are described for automatically driving a recorder under varying wireline measurement conditions. This system produces two depth signals.  First depth signals correspond to magnetic marks placed at regular intervals on the wireline. Second depth signals correspond to incremental movements of the wireline as produced by mechanically coupled measuring devices.  Such measuring devices are subject to slippage, variations in circumference, etc... There are no variations of this type for magnetic mark signals but the intervals between these signals are much larger than the mechanically produced incremental signals and are too far apart to be used to drive a recorder.  According the incremental signals are counted for each interval determined by two magnetic mark signals and compared with the number expected for such intervals, a low count indicating slippage or the like.  In one form of the invention, a low count is used to provide an appropriate alarm.  In another form, an automatic correction for the slippage is provided, the resulting corrected signals being particularly suitable for driving a recorder.
