Abstract: This is a lifting mechanism especially suited to move a stack of paper to a height so that it is easier to remove or work with. The lifting mechanism has as a bottom portion a tilting platform that receives and holds a paper stack and its support. This tilting platform will be tilted in a front down position prior to and during loading of the paper stack thereon, and will automatically tilt down at its back portion when stack loaded. This is because the fulcrum of the tilting platform is located nearer the front sections of the platform than it is to the back section of the platform. When the weight of the paper stack acts upon the tilting platform, it will force the platform down at its back portion.

Abstract: A fluid power load-clamping system includes at least one fluid valve for variably regulating the maximum fluid pressure causing closure of the clamp. Preferably the valve increases the maximum fluid pressure automatically in relation to the measured magnitude of the weight of the load to regulate the load-gripping force. A controller causes the valve to permit a relatively high maximum fluid pressure as the clamp closes toward the load to enable high initial clamp closure speed. Thereafter the valve automatically reduces the maximum pressure as the clamping surfaces close into a predetermined relationship with the load, and then increases the maximum pressure to regulate the gripping force. Other preferable features include an automatic limit on the rate of lift of the load during weighing, and compensation of the weight measurement for the longitudinally-extensible position of the lifting mechanism, to maximize the accuracy of the load-weight measurement.

Abstract: A method for handling conventional stacks of baked goods trays for the baking industry. A platen is moved underneath side-by-side stacks of trays. The platen supports the underside of the stacks of trays and prevents lateral movement of the bottom of the stacks by guiding the platen into channels that exist in the bottom of the trays. The platen is attached to an upright which is tiltable and which extends along one side of the baked goods trays when on the platen to support the stacks along their vertical height. Tilting of the upright causes the platen to lift and the trays to tilt against the upright where they are supported underneath and along the side and thus can be moved and handled. By utilizing the split platen and the tall tiltable upright with a motorized vehicle, an economical and efficient method of handing baked goods tray stacks is possible, eliminating significant manual labor and risk of worker injury.

Abstract: A lift-assist device is provided for securely clamping a wheelchair and then elevating and forwardly tipping the wheelchair to assist the occupant in rising from it to a standing position.

The present device is conveniently portable and much less expensive than wheelchairs with integral lift-assist mechanisms. Thus, the present invention provides wheelchair-bound persons with greater mobility than was previously available by greatly improving the usefulness of conventional non-lift-assist wheelchairs, which can now be given lifting assistance by the present invention in a variety of settings.
