Filed: 1991-01-07
Abstract: APPARATUS AND METHOD FOR RECOVERY OF CONSTITUENTS AND HEAT FROM FLUIDIZED BED COMBUSTION                      ABSTRACT OF THE DISCLOSURE          An apparatus and method for recovering constitu-ents and/or heat energy from a fluidized bed combustion process utilizes a single vessel (20) which combines a combustor (22) for fluidized bed combustion of a chemical mixture fed therein and a heat exchange section (24). Characteristics of the fluidized bed (36) are controlled by withdrawing an appropriate  portion of the larger, unburned constituent particles from the bottom of the combustor (22), and smaller constituent particles are withdrawn by becoming entrained within the gases of combustion and being trans-ported to the heat exchange section (24).  The smaller particles are separated from the gases without the use of a cyclone separator and accumulate as another fluidized bed in the heat exchange section (24) where heat is adsorbed from the particles for recovery purposes and to cool the parti-cles.  A portion of the cooled particles is then recirculat-ed to the combustor (22) by, for example, pneumatic trans-port methods for controlling the operating temperature of the combustion process.   The apparatus is particularly well-suited for recovering process salts and heat energy from the burning of black liquor effluent from a lignocellu-losic pulping process.

Title: Coated abrasive containing erodable agglomerates
Inventor: BROBERG DAVID E
IPC: B24D3/00
Filed: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to coated abrasives, and, more particularly, to coated abrasive products containing erodable agglomerates.  Conventional coated abrasives typically consist of a single layer of abrasive grain adhered to a backing.  It has been found that only up to about 15% of the grains in the layer are actually utilized in removing any of the workpiece.  It has long been known that a coated abrasive containing an underlayer of conventional aluminum oxide grains and a top layer of individual premium abrasive grains provides satisfactory performance at a lower cost than a coated abrasive using 100% individual premium abrasive grains.  However, for certain grinding applications, the conventional abrasive grains prevent maximum utilization of the individual premium abrasive grains that are randomly distributed between the conventional grains.  This invention provides a coated abrasive product comprising a backing bearing on at least one major surface thereof a make coat, a multiplicity of erodable agglomerates comprising a resinous binder and at least one inorganic filler material adhered to said make coat, a multiplicity of individual premium abrasive grains adhered to said make coat and disposed between said erodable agglomerates, a multiplicity of individual premium abrasive grains overlying said erodable agglomerates, and a size coat overlying said individual premium abrasive grains, said erodable agglomerates, and said make coat.  The coated abrasive products of this invention abrade faster and endure longer than coated abrasive products using individual conventional abrasive grains in place of erodable agglomerates.

Title: Process for making a thermoformed shell for a luggage case
Inventor: YOUNESSIAN ELLIOT J
IPC: B29C48/355
Filed: 1991-09-18
Abstract: Hardsided luggage cases have used thermoformed shells of generally tray-like shape. The thermoforming process usually includes the step of vacuum forming. This vacuum forming inherently causes the corner regions at the intersection of the main face and side faces of the tray-like shells to be of a thinner material than the rest of the case, leading to mechanical failure when the luggage case is abused during use. The outer face of the shell is also subject to scratching and abrasion.      The disclosed process (Fig. 5) forms a thermoformable preform (11) by pressure laminating a layer of cloth fabric (44) to one face of the thermoplastic substrate (42), preferably as the substrate is extruded and while still hot from the extrusion process. This fabric/thermoplastic laminated preform (11) can be easily processed in a matched mold press (64). The fabric (44) should be of a non-stretch type. This non-stretch characteristic, together with its intimate bonding to the thermoplastic substrate (42), prevents the substrate from thinning in the corner regions. Indeed, because the intimately bonded fabric (44) drags or pulls the substrate (42) from a number of directions as the corner regions are formed, the thermoplastic substrate (42) accumulates and actually thickens in the corner regions, leading to a shell (12) which is remarkably durable and aesthetically pleasing.
