Inventor: DUNNE STEPHEN TERENCE
IPC: A61M15/00
Filed: 1991-03-21
Granted: 1997-10-07
Abstract: Inhalateur à dose mesurée comprenant un piston (3) qui est monté dans une cavité (12) à l'intérieur d'un carter (1) et qui est poussé par un ressort (6) préalablement tendu dans une chambre de pression (4) de section réduite. Le ressort du piston (3) peut être tendu au moyen d'une tige de commande (31) dotée d'une poignée (32) et il peut être bloqué en position tendue à l'aide d'un dispositif de verrouillage (33). Un médicament liquide (p. ex. en solution aqueuse) est contenu dans un sac repliable (10). Des quantités mesurées du médicament sont successivement amenées dans la chambre de pression (4) et ensuite soumises à une soudaine et forte augmentation de pression, de manière à ce que le médicament liquide soit éjecté par une tête de pulvérisation (22) et réduit en un fin brouillard atomisé à faible grosseur moyenne de particule -- par exemple moins de 30 micromètres. Des clapets de non-retour (13 et 23) commandent l'écoulement du liquide dans l'appareil. La poussée de pression soudaine est causée par le relâchement du ressort du piston (3) quand on appuie sur un bouton de commande (35) raccordé au dispositif de verrouillage (33).

Abstract: An apparatus and method for analyzing one or more gases in a target area.  A modulated infrared light source produces an infrared beam that is capable of being absorbed at different wavelengths by the gases being analyzed. An optical arrangement transmits the infrared beam from the light source in a first path across the target area where a reflective element is positioned to return the infrared beam back along the first path to the optical arrangement.

Filed: 1992-02-07
Granted: 1995-02-07
Abstract: A method and system for the flexible assembly of components into an assembly at an assembly station within an assembly area in an adaptive, programmable fashion. Several programmable locators (20-28) mounted on a platform (14) work coopera-tively to receive and support components or parts (1-4) having critical positioning features at approximate locations. The pro-grammable locators then move the components so that the critical positioning features and hence the components are at desired locations. Thereafter, part position and orientation are constrained at retaining locations while the components are in their de-sired locations. Processing equipment at least partially joins the retained components either at the assembly station or at a sepa-rate processing station. One of the programmable locators may provide one of the retaining locations. Preferably, at least one sen-sor (13) mounted on one of the programmable locators provides at least one feedback signal for a control means which controls at least one programmable locator to adapt its position with respect to at least one critical feature of its part to thereby relocate the part. In this way, verification of the accuracy of the positioning and holding is provided.

Abstract: The occurrence of scratches on the recording disk due to sliding of the shutter is prevented by slidably inserting the first and the second shutters between the tray and the case on the opposite side to the recording disk accommodating portion.          The first shutter simultaneously opens and closes the case side driving shaft insert hole, the case side head insert hole, the tray side driving shaft insert hole and the tray side head insert hole.  The second shutter opens and closes the terminal hole.          The second shutter is opened independently of the opening operation of said first shutter and is held in a position where it dose not close the case side driving shaft insert hole, the case side head insert hole, the tray side driving shaft insert hole and the tray side head insert hole in the opened state, and is energized in the closing direction through the first shutter as the spring as energizing means energizes the first shutter in the closing direction.

Granted: 2001-09-11
Abstract: A web winding system (10) for winding adhesive backed web (12) on cores (14) mounted on wind-up spindles (28, 30). The web (12) is supported on a rotating suction drum (24). A knife (32) mounted on a rotating wheel (34) cuts the web (12) against the supporting drum (24). A tab bar (68) is mounted on the wheel (34) adjacent to the knife (32), and applies a tab (60) to the web (12) in registration with the cut. In a second position of the wheel (34) a tab source (70) moves toward the tab bar (68) and applies a tab (60) to its surface (68). The knife (32) is heated by a heater (35) to a temperature above adhesive softening and below adhesive carbonizing to prevent adhesive to stick to or to accumulate on the knife (32). The web (12) is lead to the supporting drum (24) around a stationary gapping roller (18) and a retractable gapping roller (22), mounted on an arm (42) which is pivotable around roller (10). When the knife (32) has cut the web (12) the arm (42) pivots clockwise, and lengthens the distance between retractable roller (22) and supporting drum (24), thus forcing the web to slide on the drum (24), and to form a gap between the leading cut end (36') and the trailing cut end (36) of the web. The gap allows for flying transfer of the web between the cores (14) on the two wind-up spindles (28, 30).

Granted: 1998-05-26
Abstract: A  position  detector  (11,  12)  detects  a  relative position of an optical head (2) to a recording medium (1), and on the basis of the thus-detected relative position, a position detection signal (D) is generated in response to movement of a light beam (6) over a predetermined distance.          Then,  in response  to  the position detection  signal,  a comparison is made between the number (Na) of track crossing counted for the predetermined movement distance on the basis of reception of reflection of the light beam (6),  and a predetermined reference value (Nb)  for the predetermined movement distance.  Then, track crossing count compensation data (Nc) is generated which corresponds to a difference between  the  counted  number  of  track  crossing  and  the reference value, and the counted number of track crossing is corrected by use of such compensation data.
