Abstract: ABSTRACT           Apparatus for converting blocks of foamed synthetic plastic material into chips has a severing device which removes from a block a continuous layer or a series of discrete layers of foamed material, a severing device with a series of coaxial rotary disc-shaped knives which subdivide each layer into a plurality of parallel elongated strips, and a severing device which converts the strips into discrete chips.  Each chip has a substantially rhomboidal cross-sectional outline.          The chip forming severing device has a shaft which is parallel to the shaft that carries the disc-shaped knives of the device that converts the layer or layers into strips, and the shaft of the chip forming severing device carries one or more cutters with straight or helical edges.  The unit which advances the layer or layers past the disc-shaped knives of the strip forming severing device has several endless belt conveyors which advance the strips all the way into the range of the chip forming severing device.

Abstract: OPTICAL FIBER SPLICE AND METHODS OF MAKING            Abstract A low loss optical fiber splice compises first and second assemblies each of which terminates an optical fiber.  Each assembly includes a plug that has a passageway extending  therethrough with a fiber positioned therein and having an end face extending at least to an end face of the plug.  Each plug is received in a housing which has a flange at one end thereof and a bore to allow the fiber to extend therethrough.  A collar and a spring are disposed about the housing with the spring engaging the housing and the collar.  After a fiber is secured within each plug, the fiber cores are aligned with a curable optically matching adhesive material being injected between the end faces thereof.  Then the adhesive material is cured to lock the fibers in an aligned position and to secure the plugs together.  Afterwards, the collars are moved toward the housing bodies to compress the springs and the flanges are positioned in nests of a support frame.  Then the collars are released whereupon the springs cause the collars to engage the support frame and secure the assemblies thereto. Also, the springs cause compressive forces to be imparted to the interface between the fibers to maintain the splice connection notwithstanding temperature cycling.

Abstract: ABSTRACT OF THE DISCLOSURE          A simple yet effective method and apparatus control the temperature within a fluidized bed reactor within a desired range (e.g. about 800-950°C).  Particulate solids in the off-gases from the combustion chamber of the reactor are separated out, and pass through one or more of a plurality of return conduits back to the combustion chamber.  The temperature of the returning solids is controlled by positively cooling them, utilizing heat exchangers, within one or more of the conduits, and by controlling which of the conduits the solids flow through.  Valves at the top of the conduits can control the flow of solids into the conduits. Alternatively U-shaped passageways at the bottom of the conduits between them and the combustion chamber can have fluidizing air injected therein, the injected air controlling the flow of solids out of the conduits into the combustion chamber.

Abstract: ABSTRACT            A method of preparing a stabilized polybromide resin product for use in disinfecting potable water, in which water-containing porous beads of quaternary ammonium anion exchange resin are loaded with bromine.          The beads are loaded in a bromine-containing water slurry, the loading providing the beads with excess bromine above the bromine content desired in the final product.  The external water is removed from the loaded beads while leaving the beads in a moist sticky condition, the beads containing from 20 to 50% bromine based on the weight of the loaded beads.  A moisture-evaporating carrier gas is passed through a mass of the moist beads at a con-trolled temperature and velocity effective to remove internal water gradually therefrom, the bromine content of the beads also being reduced as the internal water is removed.  The gradual drying is continued until the beads are in an externally dry free-flowing condition containing less than 5% water by weight and from 17 to 47% bromine based on the final weight of the beads, whereby the resulting resin product provides increased bromine stability and more uniform bromine release.

Abstract: ABSTRACT     In a washing machine functioning according to a new principle, the washable items, particularly washable textiles, are stacked in layers in a mesh cage, which is fixed in position relative to the drum.  The wash water, as well as the drying air, flows through the preferably stationary or slowly rotating drum con-taining the washable items, is pumped off at the outlet of the casing, and returns again by way of a recirculation pipe to the inlet of the casing.  Also an intermittent rotation of the drum, for example, of 180°, is possible.  In this way, the wash water or drying air passes through the washable items first from one side then from the opposite side.  All switching procedures are electronically controlled according to a schedule.  The washable items can no longer be damaged by catching on the drum, the wash cycle is more effective and thus shorter than before, and electric energy and chemicals are saved.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a dental prophylaxis device having a pair of spaced tynes disposed on a housing provided with an axial cavity, a stationary support located on the tynes in the vicinity of the base thereof and a circular rotatable disk located on the housing between the bases of the tynes.  The circular rotatable disk rotates on a mandrel disposed in the housing cavity through a rotatable drive shaft located in a second housing.  A dental flossing thread having a non-elastic loop at one end supported on the circular rotatable disk and an elastic loop on the opposite end supported on the stationary support spans the space between the ends of tynes and reciprocates therebetween when the disk is rotated.  The process comprises contacting dentition surfaces with the dental flossing thread described and reciprocating the thread over the dentition surfaces and across the space between the stationary tynes while expanding and contracting the elastic loop in response to the tensile force on the thread and absorbing the tensile force imparted thereto when it encounters resistance and while imparting reciprocating movement to the dental flossing thread through the rotating motion of the disk.
