Abstract: Flat panels of a setting/hardening material, esp. inorganic filler and resin, are produced by feeding the mixture from a metering device onto a support, esp. a continuously moving belt. The metering device is box-shaped, with a pair of side walls, a rear wall and optionally a base; the front wall is constituted of a vertically movable or vibrating plate, which is nearest to the applied layer of material; as the material leaves the metering device through a narrow gap near the front wall, it is compacted by upward and downward movements of a plunger to smooth it out. Preferably, the plunger is itself a cranked portion of the front wall providing a horizontal surface above the conveyor. In particular for the production of plasterboard. The method enables large sized panels to be produced. Other fillers include particulate mineral and ceramic materials, such as fly ash, ground slags, crushed limestone etc. Quartz sand of average particle diameter 250 micron may also be used. The binding agent may be a 50% aqueous phenol formaldehyde solution containing 4-6% by weight phenol resin.

Abstract: Aqueous based compositions can be thickened by mixing in a thickener which is a water-in-oil emulsion. Preferably the thickener contains water soluble polyacrylamide or polymethacrylamide homopolymers or copolymers with other suitable monomers. The polymers may be slightly cross-linked. The thickeners are themselves of low viscosity and are easy to handle, but act to thicken aqueous based compositions effectively and quickly, typically dissolving in water in about one minute. They are also resistant to bacterial attack. 
     They have wide application, examples of compositions which may be thickened are emulsion paints, carpet backing compounds textile pigment printing pastes, drilling mud, latex, and wallpaper paste.

Abstract: In order to improve the gain of the input dynode of a laminated channel plate electron multiplier an apertured metal sheet (32) is disposed at a small distance (30 µm) from the outer surface of the input dynode and is used to provide a small negative field for turning back stray secondary electrons which have sufficient energy to follow trajectories across the input side of the input dynode. 
     More particularly in order to improve the contrast of an image to be produced the areas between the apertures of the input dynode (22) are masked by a material (34) having a secondary electron emission coefficient of less than 2, which material (34) is provided on the outer surface of the apertured metal sheet (32), the metal sheet (32) being spaced from the input dynode (22) by an insulating material (36). A potential of the order of -10 V relative to the input dynode is applied to the apertured metal sheet (32). By masking the flat areas of the input dynode (22), the secondary electrons to be turned back are generally those from the part of the wall (16) of the dynode furthest from the influence of the second dynode.

Abstract: An improved wet electrostatic precipitator (10) includes several flat collector electrodes (12) and flat discharge electrodes (14) respectively arranged between the collector electrodes. Water or another suitable rinse liquid is distributed over the operative surfaces of the collector electrodes by a liquid distribution arrangement comprising several tubular distributor members (60), each member including uniformly spaced, tubular overflow nozzles (62 and 63) that project vertically upwardly and that are individually adjustable to provide for uniform flow. The end overflow nozzles (63) adjacent the respective inlets (64) have closed lower ends and circular inlet apertures or bores (94) in their tubular walls (90) and each is oriented so that the aperture (94) generally faces toward the associated distributor member inlet (64). The construction and orientation of the end nozzles (63) assures adequate flow of rinse liquid from the turbulent flow region of the distributor members, thereby in use avoiding dry spots on the collector electrodes (12) and the resultant sparking that tends to occur at any dry spot.

Abstract: A molded insulating insert of expanded polystyrene has a central section and hingedly connected side sections which are bendable toward each other to bring the insert to a U-shaped configuration for insertion in a building block cavity. The hinges are formed to provide resistance to full ninety degree bending of the side sections so that the insert side sections are inclined slightly outwardly in a free condition. On flexing inwardly and insertion in a block cavity the side sections tend to spring outwardly and frictionally grip the walls of the cavity. Lug-notch connection means frictionally retain the inserts in the U-shaped configuration and prevent dislodgement of sections in the event of hinge rupture. In molding the inserts, a transfer process is employed with the hinges partially formed in a hot mold and thereafter fully formed in a cold mold. The polystyrene is compressed in the hinge area to a higher density for hinge integrity. Density in the hinge area is approximately doubled. Reflective foil is also applied to the inner surfaces of the side sections.
