Abstract: A non-contact light beam scan system small enough to fit into a hand holdable wand, pen or calculator size terminal incorporates a novel scan element which can scan at rates of ten to hundreds of scans per second in one or two dimensions. The device is immune to low frequency vibrations and can scan large angles of 60 degrees or more. Automatic trigger circuitry enables it to be used equally well in hand held or fixed mount applications. The depth of operating range is extended with a novel focal system which is integrated with the light source. The entire scanning system for generating a beam, focusing the beam electronically, scanning the beam, collecting light from a target and converting it into electrical signals, and automatically generating a trigger signal can work with industry standard low or high speed bar code decoders.

Abstract: A continuous solvent pulping process is practiced with oxygen free gas (e.g. nitrogen) purges of all major treatment vessels during the time when the process is arrested or terminated. The wood chips or other cellulosic fibrous material to be pulped is steamed in a first horizontal steaming zone at pressure of about 10-20 psi, and then in a second horizontal steaming zone at a pressure of about 20-75 psi. The first and second zones are isolated by a low pressure feeder. Steam is introduced into the material in the second steaming zone to flow cocurrently with it. Gases, including vaporized solvent (e.g. ethanol or other alcohol) are vented from the steaming zones, and solvent is added to the steamed material prior to feeding to a high pressure feeder. The high pressure feeder introduces the material into the top of a single digesting vessel, liquid and chips being separated at the top of the digester vessel without mechanical means that could cause a spark.

The focused light rays are scanned across the bar code target with a beam scanner. While the focused light rays are being scanned, the focal length of the lens is continuously varied.

Abstract: A method of monitoring and inspecting an edge of strip metal includes providing at least one image producer having a field of view that substantially frames the edge, using the at least one image producer to form a first series of images of the edge after the edge has been formed by a knife; and analyzing in real time the first series of images to determine the shear angle and/or the burr height of the edge.

Abstract: A computer-implemented system for auditing a total exposure of an entity, the total exposure forming the basis of a premium amount to be charged to the entity for an insurance policy. A first means for receiving a plurality of exposure information records from a first source is provided. Each of the exposure information records from the first source corresponds to a location of the entity and a class code associated with the location of the entity. A database, coupled to the first means for receiving, is provided for storing the exposure records from the first source.

Abstract: A method for correcting the shape of a semiconductor structure. According to the method the shape of a semiconductor structure is initially determined to discern the presence, location and magnitude of structural deformities including warp and bow. Information derived from the topography of the structure is then used to control a heating apparatus. More particularly, individual zones or elements of a multiple zone heating assembly are selectively controlled to direct heat radiation of nonuniform intensities toward different regions of the structure to effect non-isothermal conditions within the structure and thereby reduce deformities that were determined to be present in the structure prior to shape correction.
