Abstract: Un récipient contenant une solution prévue pour être administrée par voie parentérale possède un orifice d'accès à double usage, utilisé à la fois pour administrer des fluides à un patient et également pour ajouter des fluides dans le récipient, ce dernier comportant une paroi généralement cylindrique traversée par un passage axial. Un moyen de fermeture étanche au fluide, possédant un élément de fermeture supplémentaire qui comporte une fente afin que ce dernier puisse être perçé à l'aide d'une canule métallique émoussée ou d'une aiguille pointue, est fixé de manière amovible à l'orifice d'accès à double usage. Lorsque l'orifice d'accès à double usage est utilisé dans sa condition permettant d'ajouter un fluide, l'élément de fermeture supplémentaire est fixé à la paroi pour qu'on puisse y faire passer une canule émoussée. Après avoir inséré totalement la canule émoussée, on peut ajouter des fluides dans le récipient. Afin d'utiliser l'orifice d'accès à double usage dans sa condition permettant l'administration, le moyen de fermeture est totalement retiré de la paroi. On insère dans la paroi une pointe de perçage qui forme une fermeture étanche au fluide de sorte que les fluides puissent être administrés à un patient.

Date Feb. 23, 1995A cartridge has a case comprising a body (10) housed telescopically within a sleeve (14). The body encloses a main chamber (21) which contains gas under pressure, and a valve mechanism for venting gas from the chamber (21) into an expansion chamber (61). The pressure of the gas in the expansion chamber causes the body (10) to move rearwardly relative to the sleeve (14) to apply a force to the breech block of the weapon in which the cartridge is used, thereby to initiate the reloading cycle. Gas is vented from the expansion chamber to eject a projectile when a spigot (51) projecting from the body is withdrawn from an aperture (53) in the end wall of the sleeve.

Title: Papermakers fabric having a single layer of cross machine direction yarns
Inventor: LEE HENRY J
IPC: D21F1/00
Filed: 1991-03-15
Abstract: The present invention is directed to a papermakers fabric which provides for usage of high aspect ratio yarns as structured weave components. The fabric comprises a system of flat monofilament machine direction yarns (hereinafter MD yarns) which are woven in a selected weave construction which provides stability to the fabric. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. the lower MD yarns may weave in an inverted image of the upper MD yarns to provide floats on the bottom fabric surface or may weave with a different repeat to provide a different surface on the bottom of the fabric.             At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. In the preferred embodiment, the same type and size yarns are used throughout the machine direction yarn system and both the top and the bottom MD yarns weave contiguously with adjacent top and bottom MD yarns, respectively. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1.

Title: Drive circuit for display device
Inventor: ONODERA JUNICHI
IPC: G09G3/294
Filed: 1996-07-15
Abstract: In a display device in which each group of plural drive elements 10 takes charge of the drive of plural picture elements (pixels) and the display luminance changes as the number of sustaining pulses changes that are supplied to PDP16, a constant emission luminance characteristic is maintained by increasing the number of sustaining pulses for larger load when the display load factor is large, and decreasing the number of sustaining pulses for smaller load when the display load factor is small. When displaying multi-tone image by subfield drive method, a display area detect circuit 20 allows to display image always with constant luminance characteristic despite the variation of the display load factor, and to prevent the deterioration of tone characteristic due to the subfield drive method, and further a half tone display circuit 30 allows to decrease the bit number thereby simplifying the configuration of the display area detect circuit 20.

IPC: B41M5/52
Filed: 1996-03-14
Abstract: An improved thermal ink jet recording paper, incorporating heat aged and/or milled precipitated calcium carbonate ("PCC") and a binder, is disclosed. The heat aging and milling processes produce discrete particles of PCC with a surface morphology and chemistry that enhances the ability of the PCC to bind to ink jet ink without binding so strongly that the color of the ink is changed. Ink jet recording papers incorporating the PCC and binders of the present invention have been produced that are superior to multipurpose office papers with reduced feathering, spreading, and penetration or backside showthrough, as well as improved optical density, dry time, and water fastness. The ink jet recording paper of the present invention is comparable to silica based commercial papers, at a fraction of the cost.
