Abstract: The disclosed simulation environment, methods, and system support simultaneous design and analysis of assemblies with unified computer aided design (CAD) and finite element analysis (FEA). The system provides a simulation environment that is unified with the architecture of the assembly environment, which significantly reduces the amount of time it takes to set up structural simulations as compared to prior simulation tools. The system enables CAD designers to obtain accurate mechanical guidance such as strength and rigidity early and often in the design process, seeing the structural impact of CAD modifications at the sketch, part, and configuration level. Such guidance can be particularly helpful when CAD engineers are determining product fit and form, defining dimensions, and shaping the overall weight and volume of designs.

Abstract: A padded sleeve made from a durable and resilient material, capable of being secured to an automobile lifting arm. The padded sleeve is removable, yet securely attachable so that it remains in place during use. The sleeve includes a rubber grip that covers the top of the automotive lifting arm, providing a tactile surface for secure footing on top of the lifting arm.

Abstract: A vendor comprising a cabinet having a front door and shelves in the cabinet for holding items to be vended, the shelves being slidable into and out of the cabinet, the vendor having a door and shelf interlock for locking the shelves in vending position in the cabinet unless the door is opened far enough to enable the shelves to be pulled out for loading without striking the door, and for locking the door in open position unless all the shelves are slid in to their vending position, the interlock operating automatically on swinging the door to open position to lock the door in open position and to unlock the shelves, and operating automatically on pushing the shelves in to vending position to unlock the door, the shelves then being automatically locked in vending position on swinging the door toward its closed position.

Abstract: An article vendor, particularly for food products such as sandwiches, salads, lunch platters and dessert items, wherein the articles are stocked on endless belt conveyors extending in rear-to-front direction in a cabinet having a front window for merchandising display of the articles. The conveyors are arranged in tiers one above another and side by side in each tier, and the vendor includes an elevator movable up and down at the front of the conveyors for receiving an article from any one (or more) of the conveyors and transporting it to a delivery station. Upon selection by a purchaser of an article on a particular conveyor, the elevator is raised to the level of the tier which includes the selected conveyor, and that conveyor is indexed forward one step to dispense the forward article therefrom on to the elevator, after which the elevator is lowered to the delivery station.
