Title: Material melting and incinerating reactor with improved cooling and electrical conduction
Inventor: SCHLIENGER MAX P
IPC: F23G5/10
Filed: 1994-07-26
Abstract: MATERIAL MELTING AND INCINERATING REACTOR WITH IMPROVED COOLING AND ELECTRICAL CONDUCTION                    ABSTRACT OF THE DISCLOSURE A reactor for incinerating and melting materials such as waste and/or toxic materials has a containment housing inside of which an upright, open-ended drum is rotatably mounted.  The drum is lined with refractory, forms a central discharge opening for the removal of incinerated and melted materials, and has an upright, outer wall.  Incineration heat is supplied by a plasma torch which is mounted to the containment housing and extends into the drum.  A steel throat ring concentric with the discharge opening is connected with the exterior of the drum; e.g. an outer drum wall, by grounding arms which extend non-radially; e.g. tangentially from a periphery of the throat ring to the inside surface of the drum wall, so that electric discharge from the torch to the upwardly oriented surfaces of the throat ring and the grounding arms is possible.  The throat ring and the grounding arms are otherwise embedded in insulating refractory material carried by a rotating base plate of the drum which has a radially open, horizontally disposed slit that extends radially from a periphery of the base plate to the vicinity of the discharge opening.  Several cooling water nozzles are mounted to the containment housing opposite the slit for directing cooling water jets radially into the slit.  The rotation of the drum generates centrifugal forces which aid in the removal of the cooling water from the slit.

Filed: 1994-08-25
Abstract: A compression adjustment mechanism for a shock absorber includes a screw cam which is screwed into a bore in the endcap of the shock absorber and which abuts the spring seat for the compression or blow off valve spring. Tightening or loosening the screw cam, relative to the endcap, causes the preload of the compression valve spring to increase or decrease, thereby increasing or decreasing. respectively, the compression forces in the shock absorber. The compression adjustment mechanism can act on the spring seat from any direction, thereby eliminating the need to selectively orient the working cylinder and compression head assembly to the outer cylinder and endcap assembly during assembly of the shock absorber.

Title: Fiber-reinforced thermoplastic molding compositions using a modified thermoplastic polyurethane
Inventor: TSENG HSIUNGTO S
IPC: C08K7/14
Filed: 1994-10-25
Abstract: Thermoplastic molding compositions and articles comprise immiscible thermoplastic polymer components and reinforcing fibers. The immiscible thermoplastic polymer components and the fibers are blended together under high shear conditions. The molding composition generally contains at least two phases and has an extremely smooth and fiber-free surface. Generally, other very good physical properties are obtained such as high heat distortion temperatures, high tensile modulus, high flex modulus, and the like are also very good. A desired blend of thermoplastic components is thermoplastic polyurethane and modified polyethylene terephthalate with glass fibers. The molded polyethylene terephthalate copolyester blended with an immiscible thermoplastic polymer, preferably modified polyurethane, and glass fibers produces thermoplastic molding compositions and articles having surprisingly superior impact strength. In addition, if the thermoplastic polyurethane is modified by an aromatic polyester polyol, and blended with a modified polyethylene terephthalate, no fibers are necessary to produce compositions having greatly improved processability.
