Abstract: An improved fluidized bed reactor characterized by a variable thickness inert liner surrounding the fluidized bed reaction zone. Such liner generates heat that is transferred to the reaction zone. The heat is generated in the inert liner by passing an electrical current through the inert liner. The inert liner is thicker at the top than at the bottom and therefore more heat is generated at the bottom of the reaction zone than the top of the reaction zone due to the increased resistance of the thinner portions of the inert liner.

Abstract: ABSTRACT         A heat stabilized slurry of bulked kaolin pigment is prepared by mixing a small but effective amount of a water-soluble cationic material such as a cationic polyelectrolyte flocculant with a kaolin clay pigment in the presence of water.  The resultant bulked clay product is dispersed to form a high solids clay-water slurry useful in making aqueous coating colors suitable for manufacturing lightweight coated publication papers or the pigment can be used as a filler for paper webs.  Slurries having stable viscosity during storage at elevated temperature and improved resistance to the formation of sediment are prepared by using as the dispersant a combination of an anionic lignosulfonate and an anionic naphthalene sulfonate formaldehyde complex in combination with a polyacrylate salt.

Abstract: Disposable adherent collars based on low cost supple sheets carrying a low-adherency pressure sensitive adhesive are disclosed.  The adherent collars of the present invention are significantly more comfortable to wear than prior art adherent collars due to the suppleness of the sheet used in the collars, and to the low-adherency character of the PSA, achieved preferably through the use of a discontinuous layer of PSA material.  Because of the suppleness of the sheet the low-adherency adhesive is effective to hold the sheet in place.

Abstract: ABSTRACT OF THE DISCLOSURE         An injection molding machine employing a mold for molding, e.g., disk-shaped recording medium carriers.  A mold-mounting plate has a front surface allowing the mold to be the mounted thereon.  A gate-cutting punch is slidably inserted in a hole extending through the plate and opening in the front and rear surfaces of the plate.  A bore extends longitudinally in the center of the punch, and an ejector pin is slidably inserted in the bore.  A gate-cutting drive cylinder is mounted on the rear surface of the mold-mounting plate, and has a piston capable of abutting against the rear end of the gate-cutting punch.  The piston is formed with a stepped bore having a large-diameter front portion and a small-diameter rear portion which are aligned on the same axial line.  An ejector rod extends through the stepped bore, and has a large-diameter portion slidable within the large-diameter portion of the stepped bore, the front end of the ejector rod being capable of abutting against the rear end of the ejector pin.  A sprue-ejecting drive cylinder is provided behind the gate-cutting drive cylinder on the same axial line, and has a piston rod connected to the rear end of the ejector rod.  Thus, the machine includes no hydraulic cylinders incorporated in the mold, thereby eliminating various drawbacks conventionally encountered.

Abstract: An improved apparatus including a localized heater that moves along the direction of conveyance with conveyed glass sheets to provide localized heating of a portion of each glass sheet to be bent without heating the rest of the glass sheet prior to its subsequent treatment. This invention is especially suitable for locally heating designated portions of glass sheets as they are heated while being conveyed through a furnace on a horizontal roller conveyor where the designated portion of glass sheets are to be formed with bends having relatively short radii of curvature at a bending station. The apparatus includes a pair of elongated localized gas heaters, each of which is positioned above the portion of the glass sheet which requires significant bending. These heaters are mounted on a carriage driven by a drive mechanism. The drive mechanism causes the carriage to move along a path parallel to the path of glass sheet conveyance to allow the heaters to continuously heat the designated portions of the glass sheet between an upstream position and a downstream position of the carriage. After the carriage reaches its downstream position, the drive mechanism causes the carriage to return to its upstream position in preparation for another cycle.

Abstract: The application disclosed a method and machine for the automatic setting of bricks onto a supporting layer. So far, prefabricated wall panels have been made by setting the bricks manually into a mold equipped with brick compartments and intended for the said panel. A separate mold had to be prepared for each different panel shape. The object of the present invention is to facilitate, speed up and decrease the cost of the setting of bricks. In the machine according to the invention, the method is carried out by feeding into a cassette conveyor (1, 2, 3, 4) a batch of filled cassettes, of which the first is directed to below the brick take-off device (5). When the cassette conveyor is full and the first cassette is under the take-off, the automatic operation of the machine is started. The brick take-off lifts the topmost brick layer from the cassette and lowers it onto a brick conveyor (6), wherefrom the brick rows are directed onto a transverse belt conveyor (8). A rotating wheel (9) has been fitted to receive one brick at a time into a compartment at its periphery and, after rotating half a round, to lower it onto a flight conveyor (10). The flight of the flight conveyor takes the brick fed by the turning device, or remains vacant if the rotating wheel has been programmed not to rotate and not to deliver a brick onto the flight. A full row of bricks is formed on the flight conveyor, and a pushing device (11) pushes the row onto a centering table (12), on which the distances between the bricks are evened out. A pick-up device above lifts the centered bricks, centering them in their longitudinal direction, and lowers them into the mold in one, two or several batches, in accordance with the desired bond, the machine moving forward one step between the lowerings in accordance with the programmed bond. The machine stops at the latest upon the panel being completed and also upon the cassettes having been emptied.
