Abstract: Un dispositif (10) d'actionnement d'une seringue est composé d'un élément élastomère (26) se fixant de façon amovible à l'extrémité de sortie (14) d'une seringue (12), et à un élément de serrage (48) permettant de tirer l'élément élastomère (26) en position distale le long du cylindre (16) de la seringue, afin de l'asseoir contre l'extrémité distale du piston (18) de la seringue. Dans les premier et deuxième modes de réalisation, l'élément élastomère (26) est fixé entre un oeillet (22) s'adaptant autour de l'extrémité de sortie (14), et une coiffe d'extrémité (24) en contact avec l'extrémité distale du piston (18). Quand l'oeillet (22) est assis autour de l'extrémité de sortie (14) et quand la coiffe d'extrémité (24) est en contact avec l'extrémité distale du piston (18) en position retirée, l'élément élastomère (26) est étiré le long de la seringue (12), ce qui sollicite le piston (18) vers sa position insérée. Lorsque l'élément élastomère (26) reprend sa configuration non étirée, il pousse le piston (18) dans le cylindre (16) de la seringue. Dans le premier mode de réalisation, l'élément élastomère (26) est composé d'une ou de deux sangles élastiques, dont la première (52) et la deuxième (54) extrémités sont fixées de façon amovible à l'oeillet (22), chaque sangle (26) possédant une partie intermédiaire fixée à une coiffe d'extrémité (24).

Title: Fluid control valve
Inventor: GERSTENBERGER GERALD ROSS
IPC: F16K1/38
Filed: 1997-02-07
Granted: 2004-12-21
Abstract: Needle valves which are seated in valve seats defined by circular edges have DELRIN® tips for the purpose of minimizing unseating torque which would otherwise be excessive due to the thermal expansion and contraction characteristics of the valve seats and the needle valves. In salt spreaders with aluminum valve seats and steel needle valves, the needle valves become stuck in the valve seats if the needle valves are seated after operation in frigid weather and the salt spreaders are subsequently garaged to raise the temperature of the valve seat and needle valves. By utilizing the DELRIN® tips, the needle valves do not become stuck.

Filed: 1997-06-16
Granted: 2004-12-14
Abstract: A method of coating the surface of a substrate, such as a film or a fibrous web, which is composed of a hydrophobic polymer. The method involves providing a solution of a first polyelectrolyte having ionizable groups and a solution of a second polyelectrolyte having ionizable groups. The two solutions then are mixed under conditions adapted to result in the formation of a nonstoichiometric polyelectrolyte complex. Finally, the surface of the hydrophobic polymer substrate is contacted with a solution of the complex under conditions sufficient to result in the coating of the surface of the substrate with the complex. The ionizable groups of the second polyelectrolyte have a latent charge opposite the latent charge of the ionizable groups of the first polyelectrolyte. Moreover, the amounts of the first and second polyelectrolytes are selected to give a ratio of the number of ionizable groups in the first polyelectrolyte to the number of ionizable groups in the second polyelectrolyte of at least about 2, and the molecular weight of the first polyelectrolyte is at least about 40,000 daltons and at least about 2 times the molecular weight of the second polyelectrolyte.

Granted: 2000-02-08
Abstract: Temperature and technology-independent self-calibrating monolithic logarithmic amplifier systems that use integrated cascades of current-summing orvoltage-summing differential-limiter gain stages are disclosed. Each stage is trimmed and stabilized by a respective bias replicator cell and a current mirror cell. The bias replicator provides a bias current control signal in response to a change in a given difference between bias currents in a differential pair of amplifiers controlled by a predetermined differential calibration voltage. The differential pair is identical to a differential pair in the limiter amplifier. The differential calibration voltage Elin is well-within the linear portion of the amplifier's transfer curve during operation, so that the proportional relation between Ek and Elin, which is the same as that between the given difference between currents and the correct bias current value IB, remains constant throughout. The bias replicator signal then varies the input bias current of the limiter amplifier to correct for temperature-related and technology-related bias-current errors. The current mirror uses an op amp connected to a calibration voltage equal to the correct limit voltage of the amplifier to detect a change from that voltage across a variable calibration resistance. The current mirror provides a signal to that variable calibration resistance to cancel that change, and to matching variable load resistances in the gain cell to correct for temperature-related and technology-related load-resistance errors.

Granted: 2008-04-08
Abstract: Methods are disclosed for increasing lift and decreasing drag on hydrofoils and swim fins. The methods include providing a hydrofoil (104) with a highly swept back leading edge portion (108) and orienting the hydrofoil (104) at a significantly reduced angle of attack in which the reduced angle of attack occurs at an angle that is substantially transverse to the hydrofoil's direction of movement through a surrounding fluid medium. Methods are disclosed for providing a hydrofoil with a substantially longitudinal recess or venting system located substantially along the center axis of the hydrofoil. The attacking surfaces of such hydrofoil are provided with an anhedral contour that forms a substantially lengthwise channel with the recess or venting system located along the center axis of this lengthwise channel.  The central recess or venting system also permits the water flowing in an attached manner along the lee surfaces of the hydrofoil to merge with the water flowing from the attacking surfaces through the recess or venting system so that lift is efficiently generated.

Abstract: Optical components intended for telecommunications purposes must be manufactured and mounted with a great degree of accuracy, since a component, such as an optochip, when mounted must be coupled optically, electrically, mechanically and thermally at the same time. In order to obtain a right-angled geometry when using surface-emitting or surface-detecting components, and to obtain a reduced optical travel path and accurate fixation of an optofibre, a reflective surface (12) which slopes at an angle of 45 degrees is arranged between a light-conducting core (16) and the active surface (10) of an optochip, and the light-conducting core has been placed closer to the reflective surface by bevelling the optofibre (9) and fitting the fibre in a V-groove a nd accurately fixating the fibre in the groove by means of a flat cover means (20). The aforesaid solutions relate generally to problems of a geometrical nature, but are able to provide important advantages in the arrangement of optical components in so-called optical micro-structur es in comparison with earlier known techniques with regard to requirements of space, signal transmission performances and manufacturing costs.
