Abstract: L'invention concerne un procédé de traitement thermique qui s'applique à des alliages d'aluminium corroyés dont il accroît de façon importante les caractéristiques mécaniques et la résistance à la corrosion sous tension.  Ce procédé est caractérisé par un chauffage avant trempe au-dessus de la température de brûlure, tout en restant au-dessous de la température de début de fusion à l'équilibre.  La phase liquide formée de façon temporaire est résorbée progressivement, tandis qu'on évite la formation de pores par une teneur en hydrogène du métal suffisamment basse.  L'application de ce procédé à plusieurs alliages d'aluminium a permis d'observer des accroissements de la limite élastique et de la charge de rupture de l'ordre de 7% et une contrainte de non-rupture sous tension en 30 jours au moins égale à 30 hb.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a method of reclaiming nickel values from nickeliferous alloys, such as ferro-nickel and including nickel, reclaimed by the method   The specification discloses a method of reclaiming nickel values from a nickeliferous alloy with a wider permissible range  of iron and nickel contents, which method does not require elaborate crushing of the starting material.  The invention also relates to a method of the afore-mentioned kind which, from the first step onwards, can be used to eliminate the iron in an environmentally acceptable form, and to eliminate certain impurities such as chromium, aluminium and silica.  Another object of the invention is to reclaim a nickel salt which can easily be converted into an oxide or a metal The method of reclaiming nickel value from a nickeliferous alloy, such as ferro-nickel, according to the invention, comprises sub-jecting the nickeliferous alloy to nitric lixiviation and recovering nickel values from the resulting nickel nitrate solution.  Such nitric lixiviation of the nickeliferous alloy is advantageously performed at a temperature between 80 and 100°C, using nitric acid preferably in aqueous solution and having a normality between 1N and 14N, preferably between 5N and 10N.  The lixiviation process is more efficient if the nickeliferous alloy is in granulated form, the granules having an average size of the order of a millimetre Preferably, the nitric lixiviation is performed in the presence of oxygen, usually either from the air or injected into the reactor

Abstract: METHOD AND APPARATUS FOR MONITORING LIQUID LOADING           WITHIN A FRACTIONATING PROCESS SYSTEM FOR THE        PURPOSE OF PROVIDING NOVEL CONTROL CHARACTERISTICS                          USEFUL THEREIN   ABSTRACT OF THE DISCLOSURE         In accordance with the present invention, liquid load-ings on one or more trays of a fractionating column is monitored to provide a surprisingly useful control characteristic related to the efficiency (or lack thereof) of not only the fractionating column itself but also associated processes linked to the column.          Accurately monitoring the liquid loading within the column is provided by a liquid loading meter means of the present invention positioned within a channel connecting two adjacent trays of the column.  In accordance with one aspect of the present invention, the liquid loading meter means includes cooperative baffle means mounted interior of the channel (i) for reducing channel cross sectional flow area and (ii) in conjunction with an upright measuring weir attached at the downstream end of the cooperative baffle means, to provide a repository interior of the channel by which a reservoir of liquid condensate interior of the column can be first collected and then allowed to overflow relative to the measuring weir in a manner that provides useful information as to the liquid loading of the trays within the column.  Differential pressure measuring means is also provided with a sensing means in the vicinity of the measuring weir.  In turn, the differential pressure measuring means is connected in series to a recording means located external of the column.  Result:  As overlimit swings in liquid loading occur, corrective action, say via separate process controller means, can be quickly implemented to bring the system back to stable operations.

Abstract: Abstract of the Disclosure A forced air control valve to control the flow of air to the exhaust pipe of an internal combustion engine immediately upstream of an oxidizing catalytic converter.  The control valve when opened at a predetermined vacuum normally directs air to the exhaust pipe and when in a closed position at a low vacuum vents the forced air to atmosphere.  Upon rapid deceleration when the main valve is open, a high vacuum is exerted and a separated diaphragm actuated auxiliary vent valve is actuated to vent the main diaphragm chamber to atmos-phere for a limited period of time thereby to close the main valve which is desirable upon rapid deceleration.  An air bleed passage is provided in the diaphragm for the auxiliary vent valve diaphragm which permits the auxiliary vent valve to return to a closed position so that a vacuum can again be exerted against the main valve diaphragm.  The air bleed passage pr?vides a delay in the equalization of the pressure on opposite sides of the vent valve diaphragm which delays the closing of the auxiliary vent valve thereby delaying the return of the main valve to an open position.

Abstract: ROLL SUPPORTING AND AUTOMATIC DISMOUNTING MECHANISM   FOR ROLL TOWEL DISPENSERS AND     METHOD OF USING SAME            Abstract of the Disclosure:         A rotatable first roll end holder has dia-metrically opposed pins radially surrounded and pro-jecting axially from radial surfaces except at pin inner radial extremities where a recess extends radially between the pins and opens axially toward the roll to be supported.   The recess preferably also opens radially at opposite sides of the first holder.   A second roll end holder may consist of merely a central projection so that a roll of toweling may be supported between said holders by simultaneous axially engagement of the pins and central projection.          When sufficient toweling is dispensed from the roll to the pin inner radial extremities, the roll is released radially by the pins and pivots about the second holder projection through the first holder recess for ul-timate complete disengagement from the holder.   The first holder may be rotatably secured to a support axially pivotal about a vertical axis and a finger pro-jection may be formed on the first holder as an ex-tension of the recess with counterweighting of the first holder urging the holder to rotate with the finger projection extending horizontally and thereby permitting axial finger pressure against the finger projection to axially pivot the first holder and its support away from roll end engagement position to permit such engage-ment.   Also, a circumferentially extending, axial pro-jection extending circumferentially less than one-half a circumference may be on the second holder axially received in a circumferential groove of the roll radial-ly outwardly of the second holder central projection to adapt the holder combination to different configurations of roll ends.
