A drumbar apparatus and method that allows one mechanic positioned at the frontside of a wheel on a trailer, truck, bus or any other vehicle that utilize Dayton Wheelsâ or spoke wheels to hold a bolt head of a bolt located on the backside of the wheel to prevent said bolt from rotating while simultaneously removing or replacing a nut located on the frontside of the wheel that comprises a wrench end located at a second end portion of the drumbar apparatus used to hold a socket and wherein the socket is used to hold the bolt on the backside of the wheel, a handle located at first end portion of said wrench end, a middle section connecting the handle and the wrench end wherein the mechanic positioned at the frontside of the wheel holds the handle of the drumbar with his/her first hand and extends the drumbar apparatus through the axle housing of the wheel and holds the bolt located on the backside of the wheel with the socket and wherein the mechanic rotates the nut located on the frontside of the wheel on or off the bolt with a tool held in his second hand.

The present invention is directed to a wrap device and to methods of using a wrap device for facilitating manipulation of a stack of slides or other stackable objects in order to remove the stack from a packaging container and place within a hopper or other dispensing container. When using the device and methods of the present invention, no undue force is exerted on any particular slide within the stack, thus minimizing the risks of breakage, while stabilizing the stack such that “fanning” and slippage within the stack is substantially prevented. Further, the invention may be used to facilitate manipulation of a stack of slides without direct contact between the slides and a user's hands.

A flexible method for characterizing polymer components and the use of the same in general purpose polymer process simulation software has been developed. In this method and software apparatus, polymer molecules are defined in terms of their segments or structural units. In addition, a set of component attributes is associated with each polymer component. The component attributes are used to track information on polymer molecular structure, chemical composition and product properties, such as molecular weight averages, average copolymer composition, particle size distribution, etc. This methodology is used in a consistent manner by all key elements of simulation software, such as thermo-physical property calculations and polymerization kinetics.
