Abstract: A method for teaching economics and related practices provides a “virtual enterprise” in which various economic transactions are made. Participants or “stakeholders” in the teaching session take roles of various corporate, government, and other officials, managers, and employees. Various transactions are defined, along with corresponding transaction cards according to the transaction table of a transaction sheet. The positions of the participants may also be shown on a portion of the transaction sheet, with a cash flow statement and balance sheet shown in another area of the transaction sheet. Transaction cards are drawn singly and corresponding transactions are entered in appropriate lines of the transaction table, monitoring system, balance sheet and corresponding profit and loss statement, and cash flow statement of the transaction sheet.

Abstract: A refuse container having features which adapt it to comply with federal laws and regulations facilitating use by handicapped individuals. The dumpster may have any or all of the standard commercially available features of a front-end or rear-end loaded refuse bin for automatic overhead emptying of the trash from the bin into a garbage truck. Access for deposit of trash by non-disabled individuals is provided by at least one top lid hinged to the body of the bin over a deposit opening, preferably in a top wall of the dumpster. For access by disabled individuals, a gliding door covering a second deposit opening in a side wall of the dumpster is provided at a height no greater than 34 inches from the point of contact with the ground. The tracks of the gliding door are specially configured to prevent or minimize the collection of debris and ice which could hamper the ability of a disabled individual of minimal manipulative abilities to open the gliding door.

Abstract: A locking or latching device for double panels sharing the same opening or frame serves to secure the two panels together, to provide additional security over separate locks or latches for the two panels. The device is particularly adapted to securing two adjacent doors together (e.g., at outer storm door or screen door and a main entrance door for a residence or other structure), but is also adaptable to other double panels or closures, such as windows of various types and their associated shutters. The mechanism comprises a first generally cylindrical component which secures through the outermost panel or door, a second generally cylindrical component which secures through the adjacent relatively inner panel or door and is coaxial with the first component, and a rod which passes coaxially through the two cylindrical components.
