Abstract: A process for manufacturing, shipping and unloading substantially solid, ice-like sodium cyanide dihydrate containing essentially no liquid water. A slurry of 58 weight percent or higher sodium cyanide is rapidly cooled to the anhydrous/dihydrate transition temperature while minimizing the settling out of sodium cyanide crystals to form the product in a container. Dissolution prior to unloading is by adding heat and water or dilute sodium cyanide solution.

Abstract: Porous organic microspheres for use in HPLC are formed by coacervating a colloidal silica sol in a uniform mixture of the sol and a polymerizable organic material. The silica particles which formed the sol are removed from the microspheres with ammonium bifluoride. The remaining organic microspheres are rigid, have uniform pore sizes and distribution, and do not swell or shrink in the presence of the solvents used in HPLC.

Abstract: Electrically conductive tetrafluoroethylene copolymer compositions containing conductive carbon black have significant increased conductivity and lower effective melt viscosity when the tetrafluoroethylene copolymer has been treated with a fluorinating agent.

Abstract: A solvent-based thermosetting coating composition comprising a hydroxy functional urethane modified polyester resin and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as a hot sprayable, high solids coating composition suitable for use as chip resistant automotive vehicle primer suitable for use on body panel areas subject to chipping by stones, gravel and other road debris. Alternatively, the composition may be formulated as a high solids composition sprayable with conventional spraying equipment. The hydroxy functional urethane modified polyester resin is the product of polymerization of lactone monomers in the presence of hydroxy-containing urethane modified polyester precursor. The polymerization reaction mixture comprises between about 10 and about 80 weight percent the hydroxy-containing urethane modified polyester precursor and between about 90 and about 20 weight percent lactone monomers.

Abstract: A flex circuit and cable assembly for interconnecting printed circuit boards includes a flexible insulating substrate having a conductive ground plane formed on one side and first and second sets of longitudinally extending and interdigitated conductive traces on the other side. The traces of the first and second sets alternate with and are laterally spaced from one another and are provided with an array of connection pads formed on the conductive traces for connection to the tails of an electrical connector or header. Each connection array is defined by a first set of laterally enlarged connection pads associated with each conductive trace of the first set of conductive traces and formed along a first lateral axis and by a second set of laterally enlarged connection pads associated with each conductive trace of the second set of conductive traces and formed along a second lateral axis that is longitudinally spaced from the first lateral axis.

Abstract: A layer of plastic, either in film or coating form, is bonded to a sheet of non-woven material to form a base. When film is used, it is preferably smaller in size than the non-woven material and affixed to the top surface thereof by an acrylic adhesive. The plastic film is coated, on its exposed surface, with a layer of acrylic adhesive. When the plastic is in the form of a coating, it is bonded to the bottom surface of the non-woven material. A superabsorbent pad, smaller in size than the base, is wrapped in non-woven material and affixed to the base by the exposed adhesive layer. The remaining portion of the exposed adhesive layer forms a border around the superabsorbent pad for adhering the bandage to the skin.

Abstract: The present invention relates to control architecture for a centrifuge motor speed control system having dual processors. The processors are configured in a master-slave relationship for some predetermined subset of instrument control functions during the execution of which the slave operates under the direction of the master to effect that subset of control functions. However, each of the processors is independently responsive to a speed signal from a tachometer and is independently capable of controlling the additional instrument control function of conditionally coupling the motor to a source of energy.
