Abstract: A process for the production of a range of improved biomass material products suitable for use as a fuel and which have been derived from municipal solid waste (MSW). The process comprises the steps of delivering a stream of mixed, MSW derived biomass material into a separator which operates under negative pressure enabling the biomass material to fall down the separator while inducing a sole air stream through the falling material to create a vortex of spinning material within the turbo chamber to separate out by centrifugal action selected denser components of the biomass material enabling such to continue falling to an outlet for collection while redirecting by entrainment in the air stream the remaining biomass material to a second outlet for subsequent processing or for collection.

Abstract: A process and apparatus for processing polyvinylacetate and other similar ingredients of a gum base or chewing gum product are disclosed.

Abstract: An apparatus for separating a mixed granular material into granules of different specific gravities or ranges of specific gravity using a powered air flow is described. A divider plate is located below the air flow path within the apparatus to separate the two material flows from each other. The divider plate can be rotated about an axis and can also be translated or displaced within the apparatus in order to precisely define the separation point between the material flows. Hoppers are used to collect and discharge the separated granular materials, and a conveyor belt is provided within the apparatus to transport one of the separated granular materials to the corresponding hopper. The conveyor belt reduces clogging of the separated granular material and also allows a greater degree of separation to be maintained between the hoppers, thereby allowing standard conveyors to be placed beneath the hopper discharge openings.

Abstract: Apparatus for inspecting and sorting drills oriented in the same direction in a hopper assembly. The hopper assembly feeds the drills, one at a time, and places them in a predetermined ready location. A camera, part of the inspection assembly, mounted directly over the predetermined ready location, takes preliminary measurements and alerts the system controller that a drill is available for a high resolution second inspection for wear and then for sorting. A robot assembly then picks up the drill from the ready location and orients it in front of two high resolution cameras, also part of the inspection assembly, for a visual inspection for wear. A control assembly then analyzes the results of the inspection and determines the drill size and whether or not it needs to be re-ground. The robot assembly then sorts the drill into an appropriate predetermined bin within a bin assembly as a function of size and wear. The process is then repeated.

Abstract: A sorting apparatus for sorting items according to weight or other measurable characteristics. An elongated conveyor feeds the items to be sorted to a combined weighing and conveying mechanism, which after weighing the item, is driven in one direction or another to drop the item weighed onto a uni-directionally driven conveyor. The unidirectionally driven conveyor transports the item it receives and deposits it onto a bi-directionally driven conveyor. The bi-directionally driven conveyor is then driven in the necessary direction to transport the item it receives and to deposit it onto a selected bi-directionally driven conveyor. This bi-directionally driven conveyor, in turn, is selectively driven to cause the item it receives to be deposited into the indicated receiver for items of weight corresponding thereto.

Abstract: An automatic article stacking system wherein a plurality of articles to be stacked are arranged in layers prior to being stacked. The layers are advantageously arranged horizontally orthogonal to one another so as to enhance the stability of the stack. A measurement system is provided for determining whether any of the articles exceeds a predetermined size limit. In one embodiment which is arranged for stacking egg cartons, a determination that the egg carton exceeds the predetermined size limit signifies that the egg carton is open and, therefore, not in a form suitable for stacking. The open egg carton is conveyed under an elevator which accumulates the articles to be stacked, and to a discharge area. Thus, closed egg cartons are accumulated in layers and stacked. Successive layers of articles are stacked under prior stacked layers.

Abstract: A conveyor system transports keyboards for automatic testing by a keyboard testing mechanism located at a test station, and a discharge conveyor accepts rejected keyboards. At the testing station the keyboard and the keyboard testing mechanism are brought into a testing relationship (where the keyboards and test mechanism are located physically closer and in electrical contact); they are thereafter removed from that relationship. On the main conveyor there is a separation element for effecting a right-angular turn of rejected keyboards from the normal conveyance direction for the passed keyboards.

Abstract: A method of removing product of an unacceptable height from a product line is disclosed. In the method, a quantity of the product is arrayed in a carrier and moved to a gauging station where the array is placed between a reference plate and a corresponding array of gauging members and gauged by raising the reference plate to a predetermined height position and measuring the height of the gauging members when the gauging members are supported on the product array. The signals from the gauging station are stored and the carrier plate is moved to a rejection station where unacceptable product is selectively removed in response to the stored rejection signals from the gauging station. The carrier plate is then returned to the product line with only acceptable product still in place.

Abstract: A switch system for clearing spoiled items from an overlapped stream of paper products such as signatures has a three-flight conveyor belt transporting system whose middle flight may be rocked bodily so that its downstream belt support roll, functioning as a switch roll, is moved between an upper position in which it is leveled up with the next flight, and a lowered position for sending the stream, when made up of spoiled items, downwards under the next flight to a separate delivery. The side face of the upstream belt roll of this same next flight is covered by a cover for neatly separating the stream and switching it over into the downward parts under this next flight. Over the switch a backer roll is placed so as to have its weight supported on the stream of products (in turn supported by the switch roll). In this way the products are well gripped and controlled.

Abstract: An apparatus for receiving and handling empty beverage containers. The empty containers may be received either individually or in cartons upon a moving conveyor. An alignment mechanism separates the containers and moves them to one side of the conveyor. A switch arrangement senses cartons, so that the system can process cartons of empty containers in a different manner than individual empty containers. The containers, whether individually or in cartons, pass through an illumination station wherein they interrupt illumination falling upon a row of photocells. Output signals from the photocells are transmitted to identification circuitry together with clock signals generated in synchronism with the movement of the conveyor. The identification circuitry generates registration signals, which are used to compute value of the containers being received. A paddle mechanism shifts the cartons to a separating station, which forwards properly filled cartons to a storage area.
