Abstract: A process and an apparatus are disclosed for improved recovery of metal from dross, wherein a dross treating furnace is provided with a refractory wall or lining with good capacity to store and conduct heat. This furnace is preheated to a desired temperature by injection of oxygen to burn non-recoverable metal remaining in the residue after tapping of the recoverable metal contained in the dross. When dross is treated in such preheated furnace, the heat emanating by conduction from the furnace wall is sufficient to melt and separate the recoverable metal contained in the dross, without addition of an external heat source, such as fuel or gas burners, plasma torches or electric arcs.

Title: Collection and deposition of chopped fibrous strands for formation into non-woven webs of bonded chopped fibers
Inventor: BERRY KENNETH M
IPC: D04H1/70
Filed: 1997-04-30
Granted: 2005-08-09
Abstract: An air cannon (100), formed by associating an inlet cone (116), an air amplifier (104) and an outlet core (124) with one another, receives chopped fibers and forcefully deposits the chopped fibers on a collection surface (102) or web moving beyond an outlet end (126) of the outlet core (124). A binder is applied to the resulting mat (172) of chopped fibers, the binder is activated by the application of energy with the resulting treated mat (182) being compacted, cooled and rolled up to form a chopped strand mat package (194). For wide mats, one or more banks (130) of air cannons (100) extend across the moving collection web. The air cannons (100) of each bank (130) are alternately directed up-line and down-line of the web to reduce interference between the air cannons (100) by means of L-shaped support rods (136) which have generally horizontal and generally vertical legs (136H, 136V) which are separated from one another by acute and obtuse angles (140, 142) for up-line and down-line direction, respectively.  The air cannons (100) can also be individually adjusted to vary the aimed direction of the air cannons (100) across the web by rotation of the generally horizontal legs (136H) of the L-shaped support rods (136). The air cannons (100) forcefully direct chopped fibers to the web to overcome air turbulence within a forming hood (170) and forces due to static electricity.

Abstract: A method, system and article of manufacture for providing access frontier pages) around all accessible memory pages loaded from an object-oriented database to prevent simultaneous access by multiple threads to an initializing page. On initializing the root pages from an object-oriented database including bringing them into memory and swizzling pointers in the pages, access frontier pages corresponding to each swizzled pointer are initialized and marked as inaccessible. All pointers contained in these access frontier pages that do not point to either an initialized and accessible page such as a root page or another access frontier page have page table entries created for them and are marked inaccessible. Any dereference of a pointer that causes a fault must be an access to an object on an access frontier page. A page fault interrupt handling routine proceeds, for each of the uninitialized pages pointed to by pointers on the faulted access frontier page, to convert it into an access frontier page by initializing a corresponding page from the object-oriented database, including bringing in the page and swizzling pointers in the page, and setting up inaccessible page table entries for pointers that do not point to other frontier pages or accessible and initialized pages, and marking the page inaccessible. The faulted page is marked accessible thereafter and surrounded by access frontier pages.

Abstract: The invention concerns a roller sifting or dispersing machine for the classification or dispersing of wood chips, fibers, or similar materials, having at least one roller set composed of several rollers axially aligned in parallel and having the same rotation direction; together, these rollers form a roller bed that extends longitudinally at right angles to the rollers and is equipped with an input end for the material to be sieved and an output end for the course material, whereby each roller's upper side turns toward the output end; the rollers are equipped with numerous annular grooves axially equi-spaced and separated by annular crosspieces that form the outer sheathing surface of the roller. Adjacent rollers are arranged so that the annular cross members of one roller are opposite the annular grooves of the other roller, thus being largely closed along their circumference when viewed along the roller bed surface, but having openings for the passage of chips in the direction perpendicular to the roller bed surface. For improved sifting or classification the invention proposes that the annular grooves as well as the annular crosspieces be located perpendicular to the roller surface and that the outer sheathing surface of each annular crosspiece be equipped with circumferentially aligned teeth whose leading sides are shaped more steeply than their back edges leading to the base of the following tooth side, whereby an axial view of the annular crosspiece teeth is seen as a gradient that is in the opposite direction to that of the adjacent roller but is of the same height.

Abstract: A displacement sensor includes a magnet assembly having a housing for mounting to one of first and second relatively moveable elements. First and second magnets are mounted to the magnet assembly housing so that the north pole of one magnet confronts the south pole of the other magnet, and vice versa. The first and second magnets form a longitudinal space between them. A flux-shaping pole piece on each of the poles have configurations to sculpt fringing magnetic flux in the longitudinal space so that magnetic flux density in the longitudinal space varies substantially linearly along a line in the longitudinal space between the confronting poles of the magnets. A  magnetic field sensor assembly has a housing for mounting to the other of the first and second elements. A magnetic flux sensor is mounted to the sensor housing on the line in the longitudinal space between the first and second magnets. In one embodiment, each of the flux-shaping pole pieces has a pentagon shape in a plane of primary flux pattern, forming a narrow face confronting the longitudinal space between the first and second magnets. The narrow face of each flux-shaping pole piece is wider across the primary flux pattern than along the length of the line in the longitudinal space.

An undulating net of a first layer and an undulating net of a second layer are laid one upon the other in such a manner that crossing points of the undulating net of the first layer alternately come into contact with and are separated from crossing points of the undulating net of the second layer.   The crossing points which are in contact with each other are welded together by a welding machine. Subsequently, undulating nets of a third to n-th layers are similarly processed to form a three-dimensional netlike structure.

Title: Production of substantially monodisperse phosphor particles
Inventor: MUFTI NAHEED
IPC: C09K11/08
Filed: 1998-12-04
Granted: 2008-06-10
Abstract: The invention relates to a method for producing activated, substantially monodisperse, phosphorescent particles and particles formed thereby. The method suspends substantially monodisperse, phosphor-precursor particles in a fluidizing gas and then introduces a reactive gas to contact the suspended phosphor-precursor particles. Heating the suspended phosphor-precursor particles to a reaction temperature then forms unactivated phosphorescent particles. In another embodiment, the phosphor-precursor particles may be heated to a reaction temperature where they decompose to form the unactivated phosphor particles. The unactivated phosphorescent particles suspended within the fluidizing gas are activated by heating the unactivated phosphorescent particles to an activation temperature forming activated, substantially monodisperse, phosphorescent particles.
