Inventor: LOHRENTZ RANDY
IPC: A01D57/20
Filed: 2004-11-02
Abstract: A harvester suitable for triple windrowing operations has a cross-conveyor located behind the harvesting header for intercepting a stream of severed materials projected rearwardly from the header as the machine moves through the field. The cross-conveyor may be maintained in a raised or lowered position independently of the header so that, when the cross- conveyor is raised, the stream of severed materials from the header can be projected straight back underneath the raised conveyor to fall onto the ground generally in line with the header. For triple windrowing, a first pass is made with the cross-conveyor raised so that the first deposit is made directly behind the header on the mowed strip of the first pass. The first pass is carried out at a distance inwardly from the uncut edge of standing materials that is equal to or less than the width of the header so that a band of standing materials is left along one side of the mowed strip and the main remaining body of standing materials is presented along the other side. During the second pass, either through the main body or the band of materials depending upon the direction at which the cross-conveyor is angled rearwardly, the cross-conveyor is in its lowered position so as to intercept the stream of materials from the header, convey them laterally, and project them into a second deposit of material in the mowed strip from the first pass. The third pass is then made with the cross-conveyor also in a lowered position to form a third deposit of materials in the first mowed strip. When all three passes are complete, a total of three deposits of material are presented in the mowed strip from the first pass. An extension conveyor in the discharge area of the crass-conveyor accelerates the crop materials and is cocked upwardly to provide additional loft to the materials, thus enabling the materials to travel the extra distances needed to carry out the triple windrowing process.

Title: Method and equipment for fibre optic high-resolution, in particular confocal, fluorescence imaging
Inventor: CLADE SOPHIE
IPC: G02B23/24
Filed: 2003-07-11
Abstract: The method consists in deflecting the excitation signal at a speed corresponding to acquisition of a number of images per second sufficient for real time use and in detecting the fluorescence signal at a detecting frequency corresponding to a minimum frequency for sampling the fibers one by one. The method uses an image guide consisting of several thousands of optical fibers, an excitation signal being emitted by a source, deflected and injected by turns into the optical fibers of the guide, each excitation point of the tissue in the fiber output emitting in return a fluorescence signal collected by the fiber, then detected and digitized to form an image element. The method also provides for the focussing of the beam in the fiber output to excite a subsurface plane to produce a confocal image. The method also provides for the production of a divergent beam in the fiber output capable of exciting a micro-volume of the tissue from the surface.

IPC: B01F3/04
Filed: 2005-02-08
Abstract: A humidifier (10) is disclosed having a top portion (11), a middle portion (12) and a bottom portion (13). The middle portion is essentially a water tank which provides water to be used in humidification. The bottom portion has a floor (41) and side walls (42) extending from the floor to form a tub (43) having a select height (SH1). The bottom portion is configured so that should water be uncontrollably released from the middle portion, the water level within the middle portion (MPEWL) will reach an equilibrium level with the catastrophic water lever (CEWL) within the bottom portion below the selected height of the bottom portion (SH1). When the middle portion water lever (MPEWL) reaches the same height or equilibrium lever with the bottom portion catastrophic water lever (CEWL) the flow of water from the middle portion will cease. As this equilibrium level is below the select height of the bottom portion (SH1) the water will be fully captured and will not overflow onto the underlying floor.
