Title: Systeme de circulation et procede permettant de melanger une encre pour impression a jet d'encre
Inventor: MURAD GEORGE
IPC: B41J2/175
Filed: 2000-10-27
Abstract: La présente invention concerne un système de circulation (10) permettant de mélanger de l'encre pour impression à jet d'encre. Ce système comprend un conteneur (20), une pompe (40), un premier tube (50) et un second tube (60). Le conteneur (20) présente une surface de fond (22) et une partie supérieure (26), opposée à la surface de fond (22). La pompe (40) présente un orifice d'entrée (42) et un orifice de sortie (44). Le premier tube (50) présente une première extrémité (52) et une seconde extrémité (54). La première extrémité (52) du premier tube (50) est connectée à l'orifice d'entrée (42) de la pompe (40) et la seconde extrémité (54) du premier tube (50) comprend plusieurs ouvertures (56) qui sont très proches de la surface de fond (22) du conteneur (20). Le second tube (60) présente une première extrémité (62) et une seconde extrémité (64). La première extrémité (62) du second tube (60) est connectée à l'orifice de sortie (44) de la pompe (40) et la seconde extrémité (64) du second tube (60) comprend une ouverture (66) qui est située dans la partie supérieure (26). La présente invention concerne également un procédé permettant de mélanger de l'encre pour impression à jet d'encre. Ce procédé consiste à faire circuler des particules pigmentaires de la surface de fond (22) d'un conteneur (20) à la partie supérieure (26) dudit conteneur (20). Ladite circulation assure une agitation suffisante pour maintenir les particules pigmentaires en suspension dans l'encre et pour empêcher l'agglomération de particules pigmentaires.

Abstract: A method and apparatus are described for using a series of signals that create an illusion of a continuous ascending or descending series of pitches as call waiting or call progress or process progress signals. In a preferred embodiment, a condition appropriate for representation by a call waiting or call progress or process progress signal is detected and, in response thereto, a series of signals is generated that creates an illusion of a continuous ascending or descending series of pitches. Preferably, the series of signals is Shepard's tones and the tones are generated by generating a plurality of tones, or partials, at octave intervals, amplitude filtering the partials to produce an amplitude envelope that peaks near the centermost partial or partials, and shifting the partials upwards (or downwards) through the octave in steps that are a fraction of an octave and preferably are a semitone. Illustrative apparatus for practicing the invention comprises a detector for detecting a condition suitable for representation by a call waiting or call progress or process progress signal and a signal generator for generating Shepard's tones. Preferably, the signal generator is a digital signal processor.

Abstract: A method for producing an electrical feedthru (10) wherein a thin liquid conductive film is deposited into a shallow trough (12) of an insulating machinable substrate (14). The conductive film and substrate (14) are fired and then the resulting bound composite is ground flush with the adjacent surface of the insulating machinable substrate (14). The surface cohesion of the fired composite, and the resulting high quality surface finish of the grinding operation, combined with an elastomeric seal, create a low leakage barrier capable of supporting a pressure differential while allowing isolated electrical conduction across a pressure or vacuum envelope (P1, P2). The resulting electrical trace (16) can be soldered directly to a signal carrying wire, pin/socket, or attached via a contact spring or other mechanical attachment. No epoxies are used, thus avoiding thermal limitations and outgassing contamination.

Avant remplissage, on dispose entre les bo¹tiers une paroi (130) qui d~finit deux chambres (140, 142). Chacune de ces chambres est remplie avec l'un des mat~riaux insonorisants. La paroi peut ensuite soit Útre retir~e, soit rester en place (auquel cas cette paroi est de pr~f~rence poreuse ou perfor~e). Le remplissage des deux mat~riaux isolants peut se faire selon des densit~s diff~rentes. En cas de retrait de la paroi, les densit~s tendront ~ s'~galiser. Plus simple et moins coÛteux, ce proc~d~ de remplissage rapide permet d'obtenir un silencieux au remplissage plus homog­ne et au propri~t~s insonorisantes am~lior~es.
