Abstract: TITLE:   FABRICATION OF ALUMINUM ALLOY SHEET FROM        SCRAP ALUMINUM FOR CONTAINER COMPONENTS               Abstract of the Disclosure A composition and method whereby aluminum scrap, including consumer scrap, is recycled and fabricated into aluminum sheet and aluminum containers.  Aluminum scrap is melted in a heated furnace to form a melt composition.  The melt is adjusted to form the present composition, consisting essentially of silicon, 0.1 - 1.0%; iron 0.1 - 0.9%; manganese 0.4 - 1.0%: magnesium 1.3 - 2.5%; copper .05 - 0.4%; and titanium, 0 - 0.2%, the balance being essentially aluminum. Aluminum scrap comprising consumer scrap, plant scrap, and can making scrap is heated to form the melt composition, which requires a minimum amount of adjustment to arrive at the present alloy composition.  The composition is then cast and fabricated into sheet having strength and formability properties making it suitable for container manufacture. Container manufacture according to the process and compo-sition of the present invention comprises drawn-and-ironed can body manufacture and easy-opening end manufacture. Sheet fabrication according to the present invention comprises direct chill casting, scalping, preheating, hot breakdown rolling, continuous hot rolling, annealing, cold rolling and shearing.

Abstract: Abstract A liquid phase chemical process carried out in the presence of solid particles of supported or unsupported catalyst comprising a magnetic or magnetisable metal, for example a ferromagnetic metal such as Raney nickel, wherein at the end of the process, which may be batch or continuous, the catalyst particles in the liquid reaction mixture are magnetically flocculated by application of a magnetic field (either continuously or intermittently) the flocculated particles allowed to settle to the bottom of the process reactor and the supernatant liquid withdrawn from the reactor leaving the flocculated catalyst particles in situ in the reactor for further use.  The process enables equipment usually supplied external to the process reactor for separation of the catalyst from the reaction mixture to be dispensed with, and catalyst life is increased.  The-process has applicability to a wide range of reactions in which magnetic catalysts are used, for example hydrogenations, dehydrogenations etc.

Abstract: ABSTRACT OF THE DISCLOSURE         The usual oxygen lance, and a coating lance, are disposed in upright and spaced-side-by-side relation for selective lowering into the BOF vessel when the latter is in the normal upright position it occupies for refinement of its metallic charge. Preferably, the coating lance is lowered into the vessel immediately after the latter has been charged with scrap and molten iron and moved to its upright position. At this time the oxygen lance is in standby position while refractory coating material is forced through the coating lance and outwardly of its nozzle to coat various areas of the vessel lining. Thereafter, the coating lance is with-drawn from the vessel and the oxygen lance is inserted and the refining process is begun. At this time, the coating lance is held in standby position.

Abstract: Abstract of the Disclosure A box spring assembly which includes a generally rectangular frame and a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads.  Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having a lower column section consisting of a straight length of spring wire and an upper section consisting of a plurality of substantially horizontal torsion bars and a plurality of angularly arranged con-necting bars connected to and extending between the torsion bars so that in response to a downwardly directed bedding load, the upper section will yieldably collapse to accom-modate the load and impart a feeling of soft support to the bedding user.  Subsequently, the straight wire column carries the bedding load and imparts a feeling of firm support to the bedding user.  This combination of initial softness and subsequent firmness is desirable in bedding foundations for purposes of user comfort.

Abstract: ABSTRACT       A method is provided of  ascertaining the far field signature of an array of sound source units, each of which is small compared with the wavelength of the highest frequency of interest.  The units are fired so that the interaction between them is negligible.  This is achieved by firing the unit sequentially so that each generates all its significant radiation before the next is fired, and/or by firing more than one unit at a time and separating the units by at least one wavelength of the lowest frequency of interest.  The far field signature of each unit is measured by a pressure-sensitive detector close to the unit but in a region where the phase spectrum of the pressure field is independent of azimuth and range. the far firld signature of the array is derived from the measured signatures by summation.

Abstract: FRAMING SYSTEM FOR DEMOUNTABLE WALLS OR THE LIKE    ABSTRACT OF THE DISCLOSURE          A framing system is disclosed for demountable walls or the like in which the frame member provides a substan-tially continuous backing surface to engage the back sides of panels along abutting edges thereof.  Such frame member is provided with separate locking means at spaced intervals along the backup surface having locking portions which pro-ject into the edges of abutting panels to retain the panels against the backing surface.  Such locking means are propor-tioned to fit into kerfs formed in the edges of the panel and are shaped to provide a camming action to press the back sides of the panel into snug engagement with the backup sur-face.  The framing members may be, for example, furring strips formed of metal to secure the wall to a foreign wall, or a stud providing opposed backup surfaces for use in a wall providing panels along both sides thereof.  In one form of the invention, the locking means are formed by integral tabs cut from the material of the backup surface so that the lock-ing means do not require any additional material.  In another form of the invention, the locking means are formed as sepa-rate clips which can be mounted along the backup surface at intervals.  In the latter form of the invention, the framing member can be used, without such locking clips, with standard drywall construction, or may be used with locking clips for a demountable wall construction.

Abstract: ABSTRACT OF THE DISCLOSURE     Products such as small chocolate bars, intended to be uniformly aligned on other products passing on a con-veyor, such as pieces of dough in the manufacture of chocolate-filled cookies, are placed in a hopper hav-ing resiliently mounted walls. Beneath the hopper is a feeder comprising a cylindrical-sector-shaped feeder part. The feeder part includes a slot through which the chocolate bars can be disposed on the pieces of dough.          By means of a motor driven main crank assembly and a supplementary crank assembly, a perturbed sinusoidal motion is imparted to the feeder part, thus ensuring that the chocolate bars are consistently introduced into the feed slot, particularly in the vicinity of the walls of the hopper. A blocking and release mechanism, connected to the feeder and controlled by a sensor unit, ensures that only one chocolate bar drops on each piece of dough.
