Title: Smoke extractor for weapon barrels
Inventor: BERTILLER ROLAND
IPC: F41A13/08
Filed: 1991-05-09
Granted: 1995-12-12
Abstract: In order to reduce the concentration of propellant gases in the combat compartment, behind a weapon barrel, a smoke extractor (8) is arranged in the middle area of the barrel (7).          This smoke extractor (8) is connected to the barrel (7) so as to be gas-tight to the outside and is connected to the inside to the bore (5) of the weapon through an oblique blow-off passage (3) and through Y-shaped valve passage (2).  The valve passages (2) are closed by a non-return valve (6) in the form of a spring packet made up of stratified leaf springs.  This ensures that the smoke extractor is filled with propellant gases and also ensures very rapid closure of the non-return valve, which is decisive for achieving the desired long blow-off time for the gases through the blow off passage (3).

A method for dyeing cherries comprises the steps of charging cherries to be dyed in a container together with a dyeing solution containing the dyeing agent, degassing the contents of the container, then sealing the container and heating the sealed container. Thereby, it is possible to uniformly dye cherries approximately natural red color. Thus, cherries can be dyed in high efficiency through simple processes, i.e., without using a multistage immersion treatment. Moreover, there can be obtained cherries whose texture is not softened, which are hard and tight and which exhibit favorable taste peculiar to cherries.

Abstract: A utility tote container comprising a base panel, pair of side wall panels, and pair of end wall panels hingedly connected to the base panel.  A pair of end foldover panels are hingedly connected to each end wall panel.   The side wall panels and end wall panels are pivoted upwardly to an upright configuration,  and the end foldover panels are folded inwardly into parallel abutting contact with the exterior planar surface of the adjacent side wall panel.   End panel securing flaps are hingedly connected to each of the end foldover panels, and are received through aligned and correspondingly sized slots in the side wall panels.          The  end wall  securing  flaps  are  folded  into parallel abutting contact with the interior planar surface of the adjacent side wall panel, and are secured thereto using a releasable fastener such as mating hook and loop type fasteners.  Each end wall panel defines a centered handgrip opening, and a folded rim or shoulder extending along the length of the top edge of the end wall panel.  The portion of the end wall panel cut away to form the handgrip opening is folded upwardly across double scored fold lines, and into the interior of the shoulder between the end wall panel and the portion of the end wall panel folded downwardly to form the shoulder, thereby presenting two double-thickness folds of corrugated sheet material at the top of the handgrip opening to provide greater supporting surface or purchase when a user lifts the utility tote container.

Inventor: ABRAMSON STEVEN J
IPC: G03F3/00
Filed: 1991-12-02
Granted: 2005-08-09
Abstract: A color swatch arrangement for use in selecting colors for four-color offset printing, and a method for creating such an arrangement, involves dividing the visible spectrum into a plurality of distinct hues, and determining the proportions of yellow, red, and blue dot densities needed to create color swatches of each distinct hue. A series of lighter-and-lighter tint swatches associated with each distinct hue are created by reducing each of the yellow, red, and blue dot densities in steps. A series of darker shade swatches is created by adding a proportion of black dot density to each distinct hue and all the stepped lighter tints created from it, and a series of darker-and-darker shade swatches are produced by adding greater proportions of black dot density in stages to all the stepped lighter tints.

Title: Powerless field-corrective lens
Inventor: SASIAN-ALVARADO JOSE MANUEL
IPC: G02B9/00
Filed: 1992-04-24
Granted: 1999-01-26
Abstract: An optical lens is disclosed which is capable of correcting for imaging system characteristics such as field curvature and spherical aberration. The corrective lens comprises a single optic device and imparts no additional power into the optical system. In particular, the corrective lens comprises a plano-based device (either plano-concave or plano-convex) including a series of stepped zones where the steps are formed to be parallel/perpendicular to the piano surface of the device. The stepped profile of the corrective lens is determined to approximate a lens curvature R which will impart a curvature to the wavefront passing therethrough to essentially cancel selected inherent imaging system aberrations. In particular, a corrective lens of the present invention may be utilized to correct for field curvature, spherical aberration, or both. The corrective lens of the present invention may be formed to be either transparent or reflective, depending upon system requirements.

Title: Concrete pile cutter
Inventor: TRUDEAU LEON B
IPC: B28D1/22
Filed: 1991-07-17
Granted: 2001-10-23
Abstract: A method and apparatus are described for preparing an end of a reinforced concrete pile (68). Excessive lengths of the driven pile are cut off using a shear blade (22) that is driven through the concrete and reinforcing steel (102) of the pile. Concrete is then removed down to a certain level below the cutoff position using a pair of blades (62) that engage the surface of the pile and penetrate the surface while wedging the upper part of the pile up away from the main body of the pile. This cracks the con-crete through at the desired position. At the same time, concrete breakers (88) engage the concrete pile above the blades to frac-ture the concrete from the reinforcing steel. This eliminates the need for cutting of the piles with explosives and the removal of concrete using pneumatic hammers.
