Abstract: APPARATUS AND METHOD FOR REDUCING THE WASTE OF WELDING GAS Abstract of the Disclosure An apparatus and method is described for reducing the amount of gas consumed during welding operations. A source of relatively high pressure inert gas is supplied to an individual welding sta-tion. At the station is a pressure regulator for substantially reducing the gas pressure and having an inlet in communication with the higher pressure gas supply and an outlet in communication with the inlet of a surge tank. The outlet of the surge tank is in communication with the welding apparatus. A flow restriction is located between the regulator and surge tank to increase the pressure drop across the surge tank during the transient period. The volume of the surge tank is sufficient, and the apparatus functions, to supply a flow of gas, to the welding apparatus at the reduced pressure during transient when the welding apparatus is turned on, greater than that supplied during steady state conditions. In one embodiment, the apparatus of the invention includes a pressure gauge, pressure regu-lator, and surge tank within a sealed housing with the face of the pressure gauge positioned at one side thereof and visible externally of the housing. Access to the regulator for adjustment thereof is limited by means of a locked cover which, when opened, allows adjustment of the regulator through an opening with a suitable tool.

Abstract: T I T L E     AN ORDERED BED PACKING MODULE                       I N V E N T O R S                          J. Den Hartog J.P. Butler F.W.R. Molson ABSTRACT OF DISCLOSURE         In one embodiment of the invention a catalyst packing module  is provided which greatly enhances the vapour-liquid transfer rate in the overall hydrogen-liquid water isotopic exchange reaction between streams of gaseous hydrogen and liquid water.  The catalyst packing module  comprises alternate layers of plane sheet and corrugated sheet and is produced by rolling at least one plane sheet and at least one corrugated sheet together in-to a right  cylinder in a jelly roll configuration.  The plane sheet is a woven, knitted or felted cloth of a textile material which wicks water over its surface and the corrugated sheet is an open mesh of metal coated with a porous matrix of polytetrafluoroethylene with exposed, partially platinized carbon particles therein.  This catalyst packing module maximizes the hydrophilic surface area per unit volume of packing for the vapour-liquid transfer reaction and also the surface area of the support material (carrier) for the hydrophobic catalyst.  Al-though the packing is tight, high gas and liquid flow can be used without flooding the bed because the hydro-philic surfaces are separated by hydrophobic spacers and because the hydrophilic surfaces have a wicking action.          In other embodiments of the invention the packing module is used to advantage for any gas-liquid transfer reaction but in this application the corrugated mesh is a metal cloth does not support a catalyst and is made hydrophobic with, or of, some suitable polymeric material such as polytetrafluoroethylene, polyethylene, polystyrene,  poly-methacrylate, polypropylene etc.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for continuously crystallizing alpha mono-hydrate dextrose from dextrose-containing liquours.  The process is operated isothermally and produces a lean phase massecuite.  According to the process, a rate of agitation is employed, within a reaction zone operated in a continu-ous mode, which permits linear growth of crystals to occur at a growth rate which is surface reaction controlled.  The process may be combined with a batch process by feeding lean phase massecuite from the process into a second reaction zone operated in a batch mode.  This is done at a constantly declining temperature and produces a rich phase massecuite.          The batch process stage is also continuously agitated, but at a slower rate than the first stage continuous process to prevent excessive attrition of existing crystals while maximizing crystal yield.

Abstract: ABSTRACT OF THE DISCLOSURE        A deflection control circuit for a plural tube color television camera adjusts the deflection sawtooth waves furnished to the red and blue image pickup tubes to register that the images thereof with the image of the green pickup tube, and eliminate any centering, skew, rotation, or other errors.  The circuit includes a pair of controllable complementary transistors, with current outputs connected together in series.  An impedance is connected to the junction of the current outputs, and a sawtooth wave, furnished directly to the green pickup tube, is also supplied therethrough.  A correction signal generator preferably formed of an integrated-circuit operational amplifier, supplies a correction voltage to control terminals of the transistors so that the current through the latter changes complementarily.  An adjusted output sawtooth wave is provided from the junction of the transistors to one of the red and blue pickup tubes.  Because the correction signal generator operates at a low voltage, such as ?18V, while the sawtooth wave is provided at a high voltage, such as ?80V, a level conversion circuit is interposed between the correction signal generator and the control inputs of the complementary transistors.  This circuit can include a pair of complementary transistors each having its emitter and collector coupled through respective resistors to the low and high voltages.  Alternatively, this circuit can include a pair of complementary common-base transistors, the low voltages being applied thereto as reference levels.

Abstract: Abstract of the Invention A process is disclosed for the treatment of a hydrocarbon oil feed having a significant content of metals to lighter oil products by contacting the feed under conversion conditions in a conversion zone with a catalyst containing a sacrificial trap material sufficient to immobilize Ni-V-Na compounds. Conversion conditions are such that carbonaceous material and metals are deposited on the catalyst in the conversion zone.  The catalyst is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the carbonaceous deposits, and regenerated catalyst is recycled to the conversion zone for a contact with fresh feed. The sacrificial trap material is present on the catalyst in an amount sufficient to substantially immobilize the metal compounds in the presence of oxygen containing gas at the catalyst regeneration temperature.  A catalyst composition for the above conversion comprises a catalytically active alumino-silicate zeolite dispersed in an amorphous inert solid matrix material containing the sacrificial trap material with or without one or more selected metal additives. The sacrificial trap material preferable includes inexpensive naturally occurring or synthetic zeolites which can be ion exchanged with water soluble metal additives.
