Abstract: A bulk loading system for delivering bulk material to a storage compartment of a bulk transport vehicle through a hatch opening includes a movable positioner supporting an extendable loading spout assembly, a camera coupled to the positioner and a programmable logic controller communicatively coupled to the positioner, loading spout assembly and camera for automatically positioning the loading spout assembly over the hatch opening and filling the storage compartment of the vehicle with bulk material. The system provides accurate position information to a driver of the vehicle so that the vehicle and its storage compartments can be quickly positioned within a reach zone of the loading spout.

Abstract: An apparatus and method are provided for efficient filling of bulk containers with free-flowing bulk materials. The apparatus is configured to support multiple industrial containers and fill them with bulk materials stored in a batching hopper in an effective and expedient manner. The filled bulk material containers are transported away for storage or use. The apparatus includes a rotatable multi-container support assembly for rotating the empty containers into a filling station under the batching hopper. A controller and data logger may be provided to control the apparatus and record the type, quantity and/or weight of each batch of the bulk material dispensed into the industrial containers.

Abstract: A transportable concrete mixing plant is provided and includes a frame, a mixing drum for mixing concrete, a rail positioned above the mixing drum, and a carriage assembly mounted to the rail for positioning containers of dry premix concrete so that the premix may be dispensed from the containers into the drum. The concrete pump dispenses liquid concrete from the mixing drum and pumps it to a remote location, such as a work site.

Abstract: An automated hatch for a bulk transport vehicle includes a cover and a locking assembly. The vehicle includes a container and at least one upstanding annular flange defining a fill opening for the container. The cover is adapted to pivotally mount on the vehicle, with the cover moving between an open position and a closed position for extending over the annular flange and closing the fill opening. The locking assembly includes a driver assembly and a plurality of locking members. The driver assembly includes a plurality of pusher members, with each of the pusher members being pivotally mounted to a respective locking member. The locking members are mounted to the peripheral portion of the cover for engaging the annular flange of the vehicle for locking the cover in the closed position.

Abstract: A hatch opening and closing device for a vehicle includes a cover, which is adapted to cover and seal an opening in a vehicle and to pivot between an open position and a closed position, and at least one locking device, which is adapted to move between an unlocked position and a locked position. The locking devices includes an engagement surface for engaging the cover when the cover is in the closed position thereby locking the cover in the closed position. The cover is releasably coupled to the locking device by a lost motion device over a first range of motion and decoupled from the locking device over a second range of motion so that the locking device can be independently moved from the cover. The hatch opening and closing device further includes a driver, which pivots the locking device and cover between the unlocked position and the locked position and the open position and the closed position, respectively.

Abstract: A centering and loading apparatus for locating the center of a fill opening of a vehicle and loading bulk material into the vehicle through the opening is provided which includes a movable loading spout assembly and a locator assembly which locates the fill opening of the vehicle and is adapted to move the loading spout assembly for centering over the fill opening of the vehicle. The loading spout assembly is supported on a first support and is adapted to move along the longitudinal and lateral horizontal axes of the first support for aligning the loading spout assembly over the fill opening of the vehicle. The locator assembly includes a pair of scanning devices, for example, charge coupled devices, radio frequency sensors, and laser and infrared devices, that detect and scan the fill opening to locate the center of the opening.

Abstract: The invention provides a screen door system for double-hung entry doors. The screen door system comprises an inner screen assembly containing a frame member carrying a screen member, an outer screen assembly containing a frame member carrying a screen member, inner and outer upper tracks for slidably guiding the inner and outer screen assemblies along the length of the tracks and for limiting lateral movement of the inner and outer screen assemblies as the screen assemblies move longitudinally along the tracks, and a lower sill having an inner guide rail for longitudinally guiding the inner screen assembly and an outer guide rail for longitudinally guiding the outer screen assembly.
