A medicine delivery mechanism or fibrin injection mechanism for use in combination with an anastomosing and stapling attachment for an electromechanical device driver comprises a dispensing chamber with an elongated cylindrical cross section (although other shapes can be used) which is formed in the staple housing of the attachment in lieu of a staple port or staple ports, and which has a mouth forming a channel lined at its innermost edge perimeter with inward facing prongs or teeth. The dispensing chamber contains a sac filled with fibrin. A delivery or plunger driver travels within the dispensing chamber to press a sac of fibrin against the inward facing prongs, tearing the sac and releasing the fibrin to push the fibrin through the channel to the treatment site.

A dense phase swirl pulverized coal burner comprises a primary air channel, a direct flow secondary air channel and a outermost swirl secondary air channel; and multiple levels of pulverized coal concentration rings are arranged axially at intervals along the oil gun casing in a straight tube section of the primary air channel, so that pulverized coal air flow is distributed thickly outside and thinly inside the primary air nozzle. In the invention, dense phase pulverized coal outside the primary air nozzle passes through guide vanes, forms disturbed flow, is ejected into a furnace and mixes with high temperature backflow flue gas rapidly and sufficiently at an outlet. Meanwhile, dilute pulverized coal air flow at the center is ejected into the furnace by direct flow, ensuring subsequent mixing and combustion of pulverized coal flow. The primary air nozzle and the secondary air nozzle are provided with cone flaring structures with certain angle to effectively control appropriate mixing of secondary air and pulverized coal. The invention has advantages of strong ignition and combustion stability, good coal adaptability, low nitric oxide emission, simple primary air channel structure and small resistance, which effectively slows wear rate of parts.

The manufacturing method includes the steps of winding a fiber reinforced resin member containing a fiber and a matrix resin around a mandrel, thereby obtaining an intermediate formed body, winding a wrapping tape around an outer peripheral surface of the intermediate formed body (6) with an application of a tension, curing the matrix resin in the intermediate formed body having the wrapping tape wound therearound, and pulling the mandrel out and removing the wrapping tape after the curing step, thereby obtaining a cured tubular body. It is preferable that a fabric tape should be used as the wrapping tape. It is preferable that a tensile stress to be applied to the fabric tape (8) should be set to be equal to or higher than 5 (Mpa) and is equal to or smaller than 150 (Mpa) at the tape winding step. In the manufacturing method, the matrix resin can be effectively extracted at a subsequent step to the winding step.

An object resembling the cover of a hardbound book comprises two panels connected by a spine. The outside hinge configuration of the invention prevents the spine from collapsing, even if there are no contents between the two panels. The invention lends itself to a wide variety of book-like products (e.g., a book-like holder for a compact disc and accompanying booklet) where the contents are of changing width (thickness) or where the spine must be of a specific width, irrespective of the width of the contents, and further allows for a binding for a book to be fabricated prior to assembly or insertion of its pages. A hinged cover consistent with the invention comprises a spine and two rigid panels, each panel coupled to the spine and disposed rotatably with respect to the spine, and the spine serves as a hinge stop for each rigid panel, such that each panel, when rotated toward the other panel, is constrained from rotating substantially beyond 90 degrees with respect to the spine. A method of constructing a cover consistent with the invention comprises disposing a rigid front, rear, and spine panel core onto a sheet of pliable material, such that the width of the space between the spine panel core and the other panel cores is based on at least the sum of the thickness of the spine panel core and twice the thickness of the sheet of pliable material.

Methods and apparatus for manipulating digital images. A warping module is described that enables the manipulation of a surface by selectively deforming portions of the surface while maintaining local rigidity. The user may position multiple control points on a surface to constrain deformation. The user may specify multiple properties (e.g., translation, rotation, depth, and scale) at each control point. A mesh may be overlaid on the surface. The warping module may perform an initialization in which the properties are propagated other vertices in the mesh to generate an initial deformed mesh. The warping module may then perform an iterative optimization operation on the deformed mesh to improve the deformation while retaining local rigidity. Thus, instead of moving every pixel in the surface, the warping module moves or adjusts coordinates of the vertices of the mesh. The surface is then deformed according to the deformed mesh.
