Title: Vibration isolation insert for aircraft floor panels and the like
Inventor: HAIN HARRY L
IPC: B64C1/18
Filed: 1997-09-04
Granted: 2005-08-30
Abstract: An insert (20) used to connect aircraft floor panels (11), and the like, to supporting structure (13) includes features which function to isolate the supported panel (11) from vibrations in the supporting structure (13). The isolation of the panels (11) leads to reductions in SIL (Speech Interference Level) noise within aircraft cabins. The insert (20 ) consists of internal and external rigid components separated by a contoured elastomeric component (32). The elastomeric component (32) is preloaded when installed via a fastener (15) extending through the inner rigid component (42, 42') and attaching to the supporting structure (13). The outer (22, 22') and inner (42, 42') rigid components are sized such that the inner rigid component (42, 42') will not pass through the outer rigid component (22, 22'), thus providing a safetied installation of the panel (11). The elastomeric component (32) extends below the bottom of the outer ridig component (22, 22') and provides soft snubbing against the supporting structure during loading o f the panels ( 11 ). This allows some level of isolation while restricting motion of the panels (11).

Abstract: The invention concerns a calendering method, in which the paper or board web (W) is passed through the calender, in which calender the calendering nip (N) is formed between a heatable hard roll (11) and an endless, flexible and substantially non-compressible calendering belt (15) passed over said roll.  The heatable hard roll (11) is heated in order to plasticize the surface layer of the web (W) to be calendered placed at the side of the heatable roll, and the web (W) is brought into a preliminary contact with the heatable roll (11) before the calendering proper of the web (W). After the stage of preliminary contact (I), the press treatment proper is applied to the web (W) to be calendered in two stages. First a deformation is produced in the material web (W) in the press stage (II), after that the deformation that was produced in the press stage (II) is allowed to be reversed partially under control in a reversing stage (III), and a new deformation is produced in the material web (W), which was already once pressed and partly reversed, by pressing the web again in a finishing press stage (IV). After the finishing press stage (IV), the calendered web is supported by means of the calendering belt (15) over a certain distance before the web (W) is passed away from between the heatable hard roll (11) and the calendering belt (15).

Abstract: A multi-layer papermaker's forming fabric has stitching yarns integrated into the papermaking surface. Each of a plurality of repeating units of the fabric comprises: a set of top machine direction yarns; a set of top cross-machine direction yarns interwoven with the top machine direction yarns; a set of bottom machine direction yarns; a set of bottom cross-machine direction yarns interwoven with the bottom machine direction yarns; and pairs of first and second stitching yarns. The stitching yarn pairs are positioned between pairs of top cross-machine direction yarns. The stitching yarns of each pair are interwoven with the top and bottom machine direction yarns such that, as a fiber support portion of the first stitching yarn is interweaving with the top machine direction yarns, a binding portion of the second stitching yarn is positioned below the top machine direction yarns, and such that as a fiber support portion of the second stitching yarn is interweaving with the top machine direction yarns, a binding portion of the first stitching yarn is positioned below the top machine direction yarns. The first and second stitching yarns cross each other as they pass below a transitional top machine direction yarn. Also, each of the binding portions of the first and second stitching yarns passes below at least one of the bottom machine direction yarns. In this configuration, the stitching yarns are completely integrated into the top, or papermaking, surface of the fabric, and therefore do not adversely impact the papermaking qualities of the fabric.

Granted: 2003-12-09
Abstract: Piston destiné à un injecteur de cristallin artificiel, qui comporte une pointe mousse arrondie décalée par rapport à l'axe central de la tige dudit piston. Le décalage de la pointe permet de la pousser vers le bas jusqu'au fond de l'orifice de la cartouche. Cette poussée vers le bas contribue à empêcher la pointe de glisser par-dessus le cristallin artificiel ou de se replier à l'intérieur de celui-ci. Le décalage contribue également à éviter que les haptiques du cristallin soient piégés entre la tige du piston et l'orifice de la cartouche, ce qui risquerait de les abîmer et/ou d'empêcher la descente du cristallin jusqu'à l'orifice.

Title: Device and method for non-invasively measuring and determining moisture content and density of loose and packaged tobacco
Inventor: GREENWALD ALEXANDER
IPC: B65B19/30
Filed: 1999-07-30
Granted: 2003-01-14
Abstract: A method and a device which can be used to measure the moisture content and the internal structure of material on a tobacco bale (12), or of a bulk volume of material such as loose tobacco leaves (14), by using microwave radiation. A  microwave radiation source (28) is located on one side of the tobacco, such as the tobacco bale, and an antenna (30) is located on the opposite side of the bale. The radiation source beam (32) is transmitted through a portion of the bale and is received by the receiving antenna (36), which then produces a signal (38). This signal is used to determine the moisture content of that portion of the bale and the mass uniformity of the bale. In addition, the methods and devices described herein can also be used to measure the moisture content of a bulk volume of loose tobacco leaves, for example as these leaves travel through a silo. Also, in a method for analyzing the internal structure of packaged tobacco, the internal structure is analyzed to detect the presence of any foreign objects or matter in packaged tobacco, as well as to confirm the presence of tobacco material throughout the package. The structural data is collected from the received and/or reflected microwaves, which are also analyzed to determine the moisture content. The raw structural data are then analyzed with detection, classification, and/or decision algorithms for analysis of the raw data. Preferably, the data analysis is based on pairs of attenuations (42) and phase shifts (44) obtained by passing, microwaves at a plurality of frequencies through the package of tobacco which features foreign matter or objects, collectively termed "foreign components" and/or non-uniformities. This unique method enables achievement of high levels of accuracy and precision in detection and classification of the sample, in general, and of the foreign components and/or non-uniformities, in particular.

Title: Image analysis systems for grading of meat, predicting quality of meat and/or predicting meat yield of an animal carcass
Inventor: WHEELER TOMMY L
IPC: G06T7/00
Filed: 2002-01-15
Granted: 2009-01-06
Abstract: The invention is an image analysis system and method for grading of meat, predicting quality of meat and/or predicting meat yield of an animal. One embodiment of the invention is particularly designed to capture an image of the 12th rib cross section of the ribeye and perform an image analysis of the ribeye for grading purposes. The image capturing camera portion of the system has a wedged shaped camera housing for ease of insertion into the ribbed incision. The image capturing portion of the system further comprises a camera with a flash for consistent lighting. The camera is positioned such that it views the ribeye cross section at an angle to accommodate the wedge shape of the camera housing for ease of insertion in the incision. The camera housing also has various alignment means to facilitate the user's ability to capture images in a consistent manner. Once the image is captured either digitally or captured and converted to a digital image, an image analysis is performed on the digital image to determine parameters such as the percentage lean, total area of the ribeye, total fat area, total lean area, percent marbling, and thickness of fat adjacent to the ribeye, and other parameters. These parameters are used to predict value determining traits of the carcass.
