Abstract: A bucket elevator conveyor comprises a frame housing (1) incorporated a track to route a pair of parallel chains (2) carrying buckets (3) pivotally mounted (11a, 30) therebetween through an endless circuit including loading (14) and discharge (20) stations. The chains consist of links (12) connected together by pins (11) pivoting in elongated holes (25) such that the chains are shorter in compression than when under tension, the ends of adjacent links (12) including interengaging portions (40, 41) to cause the chains to adopt a relatively stiff state when in compression. The chains (2) are maintained under compression in a section of track at the loading station (14) by two pairs of sprockets (6, 8) positioned at the entry and exit ends of the section and spaced apart to maintain the chains under compression, the sprockets (6) at the entry end being driven by an electric motor drive (15). The spacing of the buckets (3) is such that when the chains (2) are in compression at the loading station (14) the end edge portions of adjacent buckets (3) are in contact, and when the chain is under tension at the discharge station (20) the buckets (3) can be rotated through 360° without colliding.

Abstract: Optical control of array antennas in a radar and communication application is described. The opto-electronic architecture simplifies the antenna element interface unit (AEIU) by executing the phase control function in a central processor unit, thus lowering the fabrication cost, and providing greater stability of the phase control. This architecture further eliminates the need for a distribution network for the phase control information. Dynamic amplitude control is performed in a specific number of locations.  Signal distribution is done through a fiber-optic network allowing a more flexible and lighter distribution network with lower propagation loss and immunity to electromagnetic interference.

Title: Test sample card
Inventor: O'BEAR RAYMOND E
IPC: G01N1/18
Filed: 1996-05-15
Granted: 2000-08-08
Abstract: A test sample card has a fluid passage network provided on both sides of the card to provide for maximum separation distance between adjacent growth wells. The card also has cored sections along its periphery adjacent the wells, which improve the flow of plastic during the molding of the cards. The cored sections control the formation of knit lines in the surface of the card and eliminate knit lines from forming that could potentially bridge adjacent wells. These features, singly and together, combine to produce a card that is essentially immune to cross-talk between adjacent wells, yet permit a greater number of wells in a card of given dimensions. Improved bubble trap features are also provided for the card, including a bubble trap passage having a restriction formed therein. The restriction prevents air bubbles in the bubble trap from migrating back to the growth wells.

Abstract: A noise abatement system for a large caliber gun includes a gun muffler and a projectile stop, both of which are mounted on a concrete slab.  The gun muffler can be coupled at an end to a gun tube of the gun and serves to attenuate pressure waves caused by the firing of a projectile by the gun. The projectile stop is longitudinally aligned with the gun muffler and serves to selectively stop projectiles fired by the gun and to selectively permit projectiles to pass. The projectile stop preferably has an opened first end closest to the gun muffler and a second end to which a door is mounted. When it is desired to aim for a target beyond the projectile stop, the doors are opened to permit the projectile to pass through the projectile stop unhindered. When the projectile stop is used to stop projectiles, the doors are closed and the projectile stop is filled with a particulate material, such as sand.

Abstract: A speech analysis means and a window locating means are implemented in a speech coding apparatus. The speech coding apparatus encodes input speech per analysis frame defined having a fixed length and is offset at fixed interval.  The speech analysis means extracts frequency spectrum characteristic parameters of the input speech taken within an analysis window.  The location of the analysis window is specified by the window locating means.  The window locating means selects the location of the analysis window which is used in extracting the frequency spectrum characteristic parameters at the speech analysis means.  In this case, depending upon the characteristic parameter of the input speech within and near the frame concerned, the window locating means selects the location of the analysis window within the range which is not to be exceeding the range of the frame concerned.

Title: A method for matching a colour formulation
Inventor: KETTLER WILHELM
IPC: C09D7/80
Filed: 1997-09-09
Granted: 2005-06-14
Abstract: This invention relates to a method for matching a colour formulation to a colour shade model in the field of a colour- and/or effect-imparting surface coating. The reflecting surface of a colour shade, which is to be rematched, of a coloured surface coating is determined metrologically over the visible spectral region using a goniometric spectral photometer with variation of the angle of measurement. The associated standard tristimulus values and/or the vectors in the CIELAB colour solid which are derived therefrom are calculated from the measured reflection factors or spectral energy factors. Those formulations and/or colour shades which exhibit reflection properties or properties derived therefrom which are the most similar to the measured colour shade model are subsequently identified from a formulation database by means of the reflection spectra or the colorimetric dimensional numbers derived therefrom. By means of a computer-generated effect matrix, the metrologically determined, angle-dependent colour difference between the desired colour shade, i.e. the colour shade to be rematched, and the actual colour shade, i.e. the colour shade corresponding to the nearest formulation from the formulation database, is minimised by means of a computer algorithm for function minimisation taking into consideration secondary conditions in the sense of the L2 standard, and a corrected formulation is produced.

Title: Multifold balloon for stent deployment
Inventor: FISCHELL DAVID R
IPC: A61F2/90
Filed: 1997-12-18
Granted: 2006-08-01
Abstract: Prior art balloons on balloon angioplasty catheters have two folds to wrap the balloon tightly around a distal portion of the balloon angioplasty catheter prior to balloon inflation. When using such a two-fold balloon to deploy a stent having (as is typical) more than three cells disposed circumferentially around each cylindrical segment of the stent, the cells of each segment frequently expand unevenly. That is, after balloon inflation some cells are expanded more than some other cells which is certainly undesirable. The present invention overcomes the disadvantages of prior art devices by utilizing a balloon with three or more folds to more evenly distribute the frictional forces on the inside of the stent during stent deployment thus improving the uniformity of stent cell expansion. Ideally one would like to have the same number of balloon folds as the number of stent cells distributed circumferentially around the stent. Matching the number of balloon folds to the number of cells of each cylindrical segment of the stent provides better size uniformity for the stent cells after they are expanded against the wall of an artery or some other vessel within a human body.
