Abstract: ABSTRACT OF THE DISCLOSURE    Novel shredded tobacco stem material having a much lower burn rate  than other  stem material and other beneficial properties and useful in the formation of cigarettes is disclosed.  This product may be formed by a procedure which involves an initial thorough soaking of the  stem material to a relatively high moisture level and mechanical fiberizing of the soaked material in  a  disc  refiner  at  atmospheric  pressure  and preferably  at  ambient  temperatures.   The  resulting shredded stem material in fibrous form is dried to the desired moisture level.

The flow directing member snugly rotates about a portion of the chamber on an axis.  The flow directing member also includes at least one aperture therethrough which is spaced from the axis and which is selectively positionable so as to allow flow communication between the inlet and a selected outlet.  Preferably, the flow directing member is hemispherical in shape and includes two apertures spaced 90 degrees to each other relative to the axis and the housing includes a pair of outlets spaced 180 degrees from each other relative to the axis.  In addition, the valve is normally utilized in conjunction with at least one pressure relief mechanism such as a rupture disc associated with one of the outlets thereof.  The valve is normally positioned so as to flow communicate the inlet thereof with the relief device.  The flow directing member is manually or automatically rotatable when pressure has damaged the relief device to flow communicate the inlet with the other outlet so as to allow repair of the damaged device.  In another embodiment, the valve may have a plurality of outlets while the flow directing member may have one or more apertures so as to allow flow from an inlet to any of many outlets or alternatively, flow from several inlets to respective outlets.

Abstract: CONCURRENT, IMAGE BASED, REJECT-RE ENTRY REPAIR SYSTEM AND METHOD            Abstract of the Disclosure A method and system for processing a batch of documents such as checks for achieving concurrent, reject re-entry and repair of rejects of the batch of documents in association with a sorting machine.  A document reader such as a MICR reader for example, and an imaging apparatus are included along the document track to generate MICR data and digitized image data for each document passing thereby.  A document whose MICR data is read correctly is routinely sorted while a document whose MICR data for a field is missing, for example, is sorted in a reject pocket.  The data needed to complete the missing field is obtained by an operator viewing an image of the document on a data entry ter-minal while the associated document which was sorted in the reject pocket is stored at an encoder coupled to the reject pocket.  The now-complete data obtained by the operator is used by the encoder to print the now-com-plete data for the missing field on the associated document.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved heating unit comprises a combustion chamber which includes a fuel-supporting perforated burning platform located a distance from the bottom of the combustion chamber.  A perforated air plenum is disposed within the combustion chamber a short distance from the combustion chamber top wall to overly a portion of the burning platform.  A blower forces air upwardly through the perforations in the burning platform to facilitate waste material combustion and the blower also forces air down-wardly through the plenum perforations against the burning plat-form to further oxygenate the flames and thereby achieve nearly complete combustion.  The pressure of incoming air into the combustion chamber forces the exhaust gases through the air passageway above the plenum and out through an exhaust pipe.  A heat exchanger, taking the form of a water jacket, surrounds the combustion chamber to cool the combustion chamber and to recover the heat radiated upon combustion of the waste combustible material.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a multi-chambered conduit insert which can be utilized to convert a single chambered conduit into a multi-chambered conduit.  In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls having curved outer surface portions and defining a plurality of parallel spaced apart coextensive chambers.          When the conduit insert is inserted within the single chambered conduit, the curved outer surface portions of at least one of the chambers in the lower half of the insert is in line-to-line contact with the adjacent inner supporting surface of the single chambered duct, thus causing only minimal contact with the interior wall of the existing conduit and enabling the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy.  In the preferred embodiment of the invention, two identical conduit inserts are disposed in back-to-back relationship and form an insert assembly for insertion into the single chambered conduit.

Abstract: Abstract OF DISCLOSURE      The present invention relates to a heat storage element having a latent heat storage material sealed in a container under a reduced pressure.  This heat storage element permits effective reduction of air in the heat storage element, and therefore, heat is smoothly transferred from outside to the latent heat storage material through the wall of the container. Accordingly, a heat storage element which has a very high heat storage characteristic is realized. Furthermore, this heat storage element, having almost no air sealed in, has a large heat storage density.  When this heat storage element is used in combination with an electric heater element, heat will be uniformly transferred from the electric heater element to the latent heat storage material, involving very small risk of part of the electric heater element being overheated.
