Abstract: ABSTRACT OF THE DISCLOSURE            A snap-acting thermally responsive actuator comprises a bimetal sheet having a U-shaped aperture defining a tongue, the sheet having been deformed to a domed configuration in a die pressing operation so that the actuator reverses its curvature with a snap-action with changes in temperature.  The actuator may carry an electrical contact and have a high electrical resistance so that currents of 2 amps through the actuator heat the actuator to its operating temperature.  The electrical resistance may be increased by forming apertures  in the actuator.

Abstract: Abstract of the Disclosure An induction-ionized, electrodeless fluorescent lamp comprises a phosphor coated, globular envelope.  An ionizable gas is contained in the envelope to produce radiation which excites the phosphor to produce light.  A closed loop, magnetic core lying partially within and partially without the envelope couples radio frequency energy into the gas to produce ionization.  The core may be bonded to a metal strap or enclosed in a metal container to improve heat transfer from the surrounding air.  Primary windings and heat radiators are attached to the core outside the lamp envelope thereby eliminating the feed-through structures of other lamp embodiments.      A radio frequency power supply and lamp base plug are attached to the envelope providing a lamp which is physically ant electrically compatible with existing incandescent-type lamp equipment.

Abstract: ABSTRACT A method of making an extruded product is disclosed which com-prises extruding fluid material through an annular die to an extrusion exit leading to the central space of the annular die while rotating the die around the axis of the annulus and collecting the extruded material on a collector while moving the collactor substantially along the axis of the annulus, wherein the collector, at least in the area where it collects the extruded material, is substantially cylindrical and is substantially coaxial with the annulus and comprises or is supported by an internal support, and in which method the speed of rotation of the die and of movement of the collector are such that the extruded material is stretched and is given a grain direction on the collector that is at a substanfial angle to the axis of the annulus, and the extruded material after solidification is released from the support.  An apparatus especially adapted for carrying out this process and featuring a rotatable annular die is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE          Color correction is provided in a high-pressure mercury vapor lamp without significant reduction in lamp lumen output.  A cerium-activated yttrium aluminate phosphor material is blended with the conventional red-emitting phosphors customarily employed, such as europium-activated yttrium vanadate and europium-activated yttrium vanadate phosphate.  The color-correcting phosphor additive is efficiently excited in its main absorption band at the 420-460 nm. region of the visible spectrum, thereby absorbing part of the 436 nm. Hg line, as is necessary to improve the color rendering index.  The emission in the yellow-green spectrum of the phosphor additive corresponds to the maximum eye-sensitivity region, thereby contributing to the lumen output of the mercury vapor lamp coated with this phosphor blend.  The class of cerium-activated yttrium aluminate phosphor additive used is identified by the general formula:                  (Y(1-x)Cex)3 Al5O12 with x having an approximate value in the range 0.004 to 0.020.          The proportion of the phosphor additive ranges from a small but effective amount up to approximately 30 weight percent of the phosphor blend with a red-emitting phosphor.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement is provided in longitudinally seam-welding a pipe-blank for welded steel pipe from the inside along a groove by the arc welding process.  Such process includes attaching a tab plate to at least a terminal end of the pipe-blank, supplying a direct electric current for welding to a consumable electrode through a cable, and moving the consumable electrode from a first end of the pipe-blank to the terminal end of the pipe-blank while effecting seam-welding.  A method is provided for eliminating a residual magnetism in the pipe-blank produced by the direct electric current for welding flowing through the cable introduced into the pipe-blank, such method com-prising:  reversing the polarity of the consumable electrode to a polarity opposite to that used for the longitudinal seam-welding, when the consumable electrode is adjacent the tab plate at the terminal end of the pipe-blank sub-jected to the longitudinal seam-welding for causing a direct electric current for eliminating magnetism to flow through the cable in the opposite direction to that of the direct electric current for welding, thereby eliminating the residual magnetism in the pipe-blank produced by the direct electric current for welding flowing through the cable introduced into the pipe-blank during the longitudinal seam-welding.  The weld thus provided is sound and sub-stantially free from welding defects.

Abstract: Le carbonate de lithium est obtenu à partir d'un silicate calciné renfermant du lithium par un procédé cyclique continu au cours duquel le silicate est décomposé dans une solution aqueuse en présence de carbonate de sodium à une température et une pression prédéterminée.  La pulpe obtenue est refroidie et lixiviée avec le gaz carbonique et la solution chargée de bicarbonate de lithium est chauffée de façon à produire le carbonate de lithium ainsi qu'une liqueur mère qui est recyclée à l'étape de décomposition.  La quantité de liquide aqueux utilisé à l'étape de décomposition est réduite au minimum et la lixiviation s'accomplit sans autre dilution. Il en résulte une contamination par les ions bicarbonates de la liqueur mère recyclée, ce qui normalement empêcherait d'obtenir un haut rendement en carbonate de lithium.  On agit sur les conditions opératoires pour réduire cet effet négatif.  De préférence, ce contrôle s'effectue en utilisant une température de réaction relativement basse et en neutralisant la liqueur mère.  Même si ce n'est pas aussi recommandable, on peut aussi effectuer le contrôle en question en utilisant une température relativement plus élevée que l'on règle étroitement.

Abstract: ABSTRACT OF THE DISCLOSURE           A blow molded collapsible solution container having improved characteristics of collapsibility as shown.  The container defines a body portion having an integral neck portion, and a semi-rigid shoulder portion at one end thereof, and is sealed at its end opposite said one end.  The body portion defines, in its original, unstressed state, generally oval, transverse cross-sections adjacent said neck and shoulder portions,said cross-section tapering progressively along a major portion of its length to a flat, sealed end portion at said end of the container opposite to said one end.  Transverse lines of folding weakness are defined along opposite edges of the shoulder portion to facilitate the collapse of said container.          Gusset portions are defined in the body portion adjacent said shoulder portion and adjacent the ends of said transverse lines of folding weakness.  The gusset portions include lines of flexing weakness to facilitate collapse of the container adjacent said shoulder portion, whereby the container collapses to a uniform flat configuration progressively from said opposite end toward said one end as the contents thereof are withdrawn through said neck portion.  The transverse lines of folding weakness and gusset portions cause the container to collapse about the inner surface of said shoulder portion as the container empties, whereby the residual volume of the collapsed con-' tainer is minimal.
