Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE         . `        A process for calcining mineral raw materials is performed in a two-shaft furnace wherein each of the shafts are alternately used as the calcining shaft and as the counterflow shaft.  Fuel is supplied in the calcining shaft by means of burners at the end of a preheating zone and the mineral raw material is calcined in a calcining zone.  Generated exhaust gases flow upwardly into the counter-flow shaft, heat up the raw material in the shaft and leave through an exhaust.  The calcined raw material is passed through an after-deacidification zone and, subsequently, through a cooling zone in which it is cooled by means of cooling air which is blown in from below.  After removal of dust, the heated cooling air is either entirely or partially conveyed either directly into a raw material preheater or  it is utilized in a recuperator for heating combustion air.

Cette capsule comprend un boîtier relié au carter de la boîte de vitesses, un poussoir sur lequel agit dans un sens un ressort et dans l'autre la dépression provenant du collecteur d'admission d'un moteur, une membrane et un soufflet d'étanchéité.  Cette capsule comprend en outre une chambre à dépression relié au collecteur et une chambre intermédiaire reliée à l'atmosphère. Le ressort se trouve dans la chambre intermédiaire qui est délimitée par le boîtier, le soufflet fixé d'une part au boîtier et d'autre part à une extrémité du poussoir et la membrane qui est fixée d'une part à l'autre extrémité du poussoir et d'autre part au boîtier.  Ce ressort qui repose sur une surface intérieure radiale du boîtier disposée entre la membrane et le soufflet et qui est relié au poussoir entre cette surface intérieure et le soufflet, agit sur le poussoir dans un sens allant de la membrane vers le soufflet, si bien qu'il entoure ledit poussoir.  La création d'une chambre intermédiaire entre le soufflet d'étanchéité et la membrane, qui est reliée à l'atmosphère et dans laquelle se trouve le ressort de la capsule, permet de protéger aussi bien la boîte de vitesses que le moteur. D'autre part, si la membrane devient non étanche, la dépression moteur crée une aspiration d'air supplémentaire au niveau de la chambre intermédiaire, si bien que le moteur est alimenté de façon incorrecte et l'utilisateur s'en rend compte avant la detérioration de celui-ci.

Abstract: METHOD OF COLD FORMING TUBES WITH INTERIOR THICKER WALL SECTIONS                                      ABSTRACT A method for cold forming metal tubes with inwardly thickened wall sections including positioning a short, tubular blank in a die having an extrusion die throat, and pushing the blank through the die throat with a punch. The punch is formed with a co-axial mandrel-like extension which fits within the blank and die throat. The extension is formed of co-axial sections of successively smaller diameter. Thus, as the punch pushes the end of the blank to move the blank through the die throat, a narrower diameter extension section fits within the die throat to extrude a thickened end portion. Thereafter, continued punch movement positions a wider mandrel forming extension section within the die throat to extrude a thin wall tube section. At a point where a wall thickened section is to be formed interiorly of the tube, the punch is removed and replaced by a different punch having a mandrel forming extension of different diameter than that mentioned above, wherein movement of the second punch results in the extrusion of a thickened tube section in the annular space between the extension section and the die throat, with continued punch movement thereafter positioning a further punch extension within the die throat for forming additional thin wall sections on the tube. The trailing end of the blank may then be provided with a thickened end section similar to the leading end of the blank by utilizing the initial punch in place of the second punch.

There is provided a series of transversely extending grouser bars fixed to and projecting outwardly from the external surfaces of the belts so as to extend across the grooves between the respec-tive adjacent edges of the central and outer belts.  Each of the grouser bars have built-in flex points and each of the flex points of adjacent bars are offset in a transverse direction from those of the adjacent bars.  Transversely extending surface lugs project from the outer surface of the respective belts and are in advance of and closely adjacent the flex point of the next adjacent grouser bar.  The lugs offer a transverse stiffness at the flex point.  The surface lugs project out further than the outer extremities of the grouser bars and are the primary contact points between the entire assembly and the ground or snow sur-face.

Abstract: Gitlin-8 - ? -PHASE-JITTER COMPENSATION USING PERIODIC                   HARMONICALLY RELATED COMPONENTS      Abstract of the Disclosure A quadrature amplitude-modulated (QAM) data signal receiver employs a phase compensation arrangement (16, 31, 33) before the equalizer (17).  The arrangement utilizes the assumption that the frequency components typically present in the phase perturbance are power-line related.  This enables an effective phase compensator to be of relatively low complexity compared to the equalizer (17).  Since the compensator is "pretuned", only the phase and amplitude of the frequency components need by adaptively found.  This makes for a relatively stable arrangement with a suitable convergence rate.  In an alternative arrangement, a phase compensator (216, 233, 240) is provided for use after the equalizer (217).

Abstract: ABSTRACT OF THE DISCLOSURE           Free oil, often an objectionable impurity in synthetic organic detergents, such as sodium lauryl sulfate, is removed from aqueous solutions by extraction thereof with hexane in the presence of lower alkanol, with the proportion of the alkanol present being in a relatively narrow range with respect to the sodium lauryl sulfate, in which range it helps to promote efficient extraction of the free oil by the hexane without solubilizing the hexane in the aqueous medium to such an extent as to result in an extracted detergent containing an unaccept-ably high proportion of hexane.  Separation of the free oil from the aqueous detergent solution is effected in an extractor, to which the hexane is added, in mixture with a minor proportion of lower alkanol, normally isopropanol, and extraction of the free oil takes place after a preliminary mixing of isopropanol with detergent acid or neutralized base in a neutralization vessel and/or in a mixer upstream of the extractor.  In a preferred embodiment of the invention the hexane extractant feed to the extractor is that resulting from distillation separation from the free oil of the hexane with some isopropanol.          Also, extracted product is evaporated and the evaporator over head, including isopropanol, hexane and water, is fed to the mixer.  The evaporator product is steam stripped, very prefer-ably in a novel stripper described herein, and the stripper overhead, including isopropanol and water, is conveniently fed to a neutralization vessel in which detergent acid, comprising the product of sulfation of lauryl alcohol with sulfur trioxide (and containing objectionable free oil), is neutralized with aqueous sodium hydroxide.  Preferably the deoiling process is a continuous one, with only free oil being removed from the extractor feed, and the hexane and isopropanol are continuously recycled.

Abstract: DUAL KEY LOCKS WITH MULTI-FUNCTION TUMBLERS                 Abstract of the Disclosure The invention provides an improved lock configu-ration by which a dual key lock can operate efficiently and conveniently with a single stack of tumblers.  That configuration permits more accurate positioning of the tumblers upon key operation, whereby a larger number of key combinations can generally be accommodated.  Also, the individual tumblers of the invention are typically receivable in the lock in a plurality of alternative orientations in which their gates assume different func-tions.  That difference of function may constitute a change of effective gate position with respect to the same key, or may shift cooperation with the two keys from one pair of gates to another.  That aspect of the inven-tion is useful in facilitating key changes, especially in locks designed for safe deposit and similar service.
