A transport drawbar for an agricultural tractor has an elongate forward drawbar section of substantially uniform rectangular cross section that mounts on the tractor in the conventional way. An elongate second drawbar section extends to the rear from the forward section. The second drawbar section has the same vertical thickness as the forward drawbar section and a substantially greater width. A trailing drawbar section extends to the rear from the second drawbar section, the trailing drawbar section having the same vertical thickness as the forward and second sections and a width substantially the same as the width of the forward section. Two tapering transition sections are provided between the second drawbar section and the forward and trailing drawbar sections respectively. Two angular offsets are formed in the second drawbar section such that the trailing drawbar section is parallel to and offset downwardly from the second drawbar section. This drawbar can be used as a conventional tractor drawbar for pulling implements in the field. It also has sufficient strength and stiffness that it can be used for transporting bulk cargo. The drawbar is manufactured by flame cutting a blank for the drawbar and die forming the angular offsets in the blank. The formed blank is heat treated. Pivot pin holes are formed in the forward section of the blank and a draw pin hole in the trailing section. The blank is then quenched and shot peened.

An apparatus and method define the concept of a “database breakpoint.” One or more conditions in the database are specified as a database breakpoint in a debug environment for debugging a computer program that accesses the database. When the database conditions exist, one or more debug functions may be performed with respect to the execution of the computer program. Examples of debug functions include halting execution of the computer program and halting operations to the database by other programs. With both the computer program and database halted, the user may then interrogate the database to determine its state, and may interrogate the program to determine its state. Database breakpoints greatly enhance the utility of a debugger by providing additional conditions for debugging a computer program that accesses a database.

A method, apparatus, system, and signal-bearing medium that in an embodiment determine whether a block of code associated with a copy-and-paste operation or a punch-out operation has a size greater than a threshold. If the size is greater than the threshold, then a method is created and the block of code is pasted into the method. Also, an invocation to the newly created method is added at the copied-from location and the intended pasted-to location (in the case of the copy-and-paste operation) or an invocation to the newly created method is added at the copied-from location (in the case of the punch-out operation). In this way, future modifications to the block of code need only be made in one place: the method, instead of at all locations where duplicate code exists. Thus, embodiments of the invention may reduce the fragility of the code.

A hitch apparatus includes a hitch member defining a draw pin hole. A hole adjusting member is movably attached to the hitch member such that a front end of the hole adjusting member can be moved forward and rearward, and a threaded actuator is operative, when rotated in a first direction, to move the front end of the hole adjusting member forward to decrease a distance between a front edge of the pin hole and the front end of the hole adjusting member, and is operative, when rotated in a second direction, to move the front end of the hole adjusting member rearward to increase the distance between the front edge of the pin hole and the front end of the hole adjusting member.

A foaming oral care composition of two parts; namely, a vinegar part, and a baking soda part. Also included are alternative additional components such as lemon oil, orange oil, xanthan gum or an oxidizing whitener such as hydrogen peroxide or sodium chlorite. Methods for making and using such an oral care composition are included as well.

A lock apparatus for a chain grab hook comprises a locking member adapted to be pivotally attached to the clevis of the chain grab hook about a pivot element located between a mid-point of the locking member and the top surface of the clevis. When installed, a bias element is operative to exert a bias force on the locking member urging the front end of the locking member to pivot upward to a closed position wherein the front end of the locking member extends into the open end of the jaw a sufficient distance to prevent a chain link engaged in the jaw from moving out of the open end of the jaw. The front end of the locking member can be pushed downward against the bias force to an open position to release the chain link from the jaw.

Methods and systems for processing multiple mailing services orders for print items of varying quantities include filling 3-dimensional gangs configured to receive print-ready items with print-ready items in a stack-wise manner. Individual stacks can be submitted to the system for reprint without holding up remaining items in an order.
