Abstract: Appareil et procédé permettant d'effectuer des analyses d'échantillon de fluide et utilisant un élément de réflectance interne cylindrique (IRE) (26) dont la surface d'extrémité est en forme de cône (28, 30). La divergence des rayons à l'intérieur de l'IRE est minimisée par le biais de cônes de réflection (32, 34) se trouvant à chaque extrémité de l'IRE, les éléments structurels et leurs dimensions étant tels que chaque rayon entrant frappe la surface d'extrémité en cône de l'IRE (28) avec sensiblement le même angle d'incidence. Des dispositifs placés aux extrémités larges des cônes de réflectance d'entrée et de sortie (32, 34) servent d'obturateurs optiques (36, 40), de manière à éliminer tout rayon qui pourrait passer au travers de l'IRE sans avoir auparavant été réfléchi par le cône d'entrée (32). Grâce à de tels obturateurs (36, 40) et aux dimensions appropriées du diamètre du cône de réflectance d'entrée (32), on obtient un système dans lequel chaque rayon entrant dans l'IRE est réfléchi une et une seule fois par le cône de réflectance (32).

Abstract: Method consisting in transforming a digital message M by an operation of exponentiation of M by a number e, modulo N, all these numbers being long integers, with n bits, which uses a suite of two successive operations, the first of the form:
 Bi = ai.X + T.2<m>
 where Bi and X are calculation variables, where ai is an m-bit extract of another calculation variable A whose value stems from a preceding operations step, which extract is taken in the decreasing order of significance of A at rank i, and T a totalisation variable serving in the calculation of A, and the second operation consisting in reducing the length of the variable Bi. 
<??>The method according to the invention uses a quasi-reduction modulo N since it is an approximation (to within a small multiple of N), and can be applied systematically and without a sign test during a given number of successive operations which is chosen and fixed. After which, a supplementary and systematic reduction is performed according to the same method. A quotient q, approached by default, of Bi/N is used, for which a p-bits format is provided, greater than the m-bits format of ai.

Abstract: The driver circuit comprises drive means (Q2) for drawing an output current from a bus line (13) in a first state of the circuit. An output diode (S1) in the path of the output current is reverse biased in a second state of the circuit to isolate the drive means from the bus line. The driver circuit comprises means (26, S3, P1) for biasing the output during connection of the circuit to a live bus line, so as to reduce noise for other circuits connected to the bus line. Further a control current (I Q2B ) for the drive transistor is drawn from the bus line (13), beyond the output diode (S1). By this means, power dissipation (heat) within the driver circuit due to the control current is eliminated.

Title: Incremental dispensing device
Inventor: ANDERSON J EDWARD C
IPC: B05C17/015
Filed: 1991-12-02
Abstract: A fluid actuated dispensing device (5) having a valve assembly (77) and an actuating piston (78) provides incremental movement of a drive piston (61) within a tube holder. The valve assembly (77) includes a trigger piston (80) and a valve ball (81) biased into engagement with a valve seat. A trigger is adapted to engage the trigger piston (80) and urge the valve ball (81) away from its seat to allow fluid to enter an actuating chamber. The increase in fluid pressure within the chamber drives an actuating piston (78) from an initial position to an extended position in the chamber. The actuating piston is adapted to drive a washer (55) off-center against a push rod (42) during the stroke of the actuating piston. The washer (55) cocks and grabs the push rod (42) and urges the rod forwardly within the tube holder (10). A drive piston (61) connected to the push rod is thereby driven forward within the tube holder for the full stroke of the actuating piston (61). When the trigger is released (110), the fluid in the actuating chamber is exhausted through a passage in the trigger piston, which thereby reduces the pressure in the actuating chamber. The reduced pressure in the chamber allows a spring (65) to uncock the washer (55) and bias the washer and the actuating piston (78) back into their initial positions, which provides for incremental movement of the push rod, and hence the drive piston.
