Abstract: Le débitmètre massique de l'invention comprend au moins une boucle tubulaire (1) qui est fixée par ses deux branches (2) à un bloc support (3) et est pourvue d'un générateur d'oscillations (4) et de capteurs latéraux (5), lesquels convertissent les oscillations mécaniques de la boucle (1) en signaux électriques analogiques de tension alternative. Un circuit électronique à deux canaux est adjoint au débitmètre massique, lequel circuit forme à partir des signaux de tension alternative un signal de mesure proportionnel au débit masse. Dans le but d'améliorer la précision de mesure, on détermine les composantes cartésiennes des vecteurs de signaux et on les évalue en liaison avec une transformation de Fourier numérique. A cet effet, les amplitudes présentes à des moments identiques sont converties en continu en valeurs de mesure numériques, au moyen d'un convertisseur analogique/numérique (12), à partir des signaux de tension alternative avec une fréquence d'échantillonnage prédéfinie. Elles sont ensuite acheminées à un micro-ordinateur qui soumet les valeurs numérisées à une transformation de Fourier en les multipliant avec les valeurs de sinus et de cosinus correspondant à l'échantillonnage et en additionnant ces produits selon une transformation de Fourier. Le micro-ordinateur (14) fournit une fréquence d'échantillonnage qui est un multiple de la fréquence des signaux de tension alternative, et commande l'échantillonnage de manière telle que les produits mémorisés dans le cadre d'une durée prédéfinie sont complétés en continu, à chaque échantillonnage, par un nouveau produit et que le produit le plus ancien dans l'ordinateur est soustrait.

Abstract: Electrical connector (2) for electrically connecting contact surfaces (74) of a daughter board (18) to contact areas (46) of a mother board (34). The connector (2) has contacts (36) positioned therein, the connector (2) having posts (38) which extend from the connector (2) and make electrical engagement with contact areas (46) of the mother board (34). The daughter board (18) is then inserted into the connector (2) under reduced or zero insertion force conditions and rotated to its operating position. As this rotation occurs, contact projections (60, 72) of the contacts (36) engage the contact surfaces (74) of the daughter board (18). The rotation is translated into a positive wiping action between the contact projections (60, 72) and the contact surfaces (74), thereby ensuring that a positive electrical connection is effected. The resilient nature of the contacts (36) ensures that this wiping action occurs under normal force conditions. The configuration and characteristics, i.e. the low spring rate of the spring portion (68), allow the contacts (36) to be used many times without taking a permanent set, thereby ensuring that a positive electrical connection is effected with each use. To prevent the daughter board (18) from warpage and bowing during use, a support member (88) is provided which cooperates with the board (18). The support member (88) not only maintains the board (18) in proper position, but also acts as a shielding member if required.

Abstract: Clamping cylinder 22 slidably receives a clamping ram 26 whose front end is fixed on a movable board 20 of (e.g.) an injection molding machine (21,23-25) and which has a chamber opening in its rear face. The interior of the clamping cylinder 22 is divided into a rear chamber W and a front chamber X by the large-diameter piston section of the clamping ram 26. From the inner rear wall of the clamping cylinder 22 there projects, a mold opening piston having a front end which slidably fits in the chamber in the clamping ram 26. The opening piston has a large-diameter piston section which divides the chamber into a rear chamber Y and a front chamber Z which communicates with the atmosphere. A hydraulic controlling device 31-37 controls the connection of the chambers X,Y and Z to each other and to an oil pressure source 40. Thus it connects the chambers X and Y to the chamber W for high-speed mold closure. It connects the chamber W to the oil pressure source 40 and relieves the pressure in the chambers X and Y for tight clamping; and it connects the chamber Y to the oil pressure source and connects the chamber W to both the chamber X and the relief means 32 for opening the mold. Preferably, the effective pressure receiving area of the chamber Y is to be equal to the cross-sectional area of the chamber section of the clamping ram 26.

Abstract: An anvil and driver assembly for a surgical skin stapling instrument (1) producing formed and implanted skin staples (24) of more consistant and perfect configuration. The anvil (12) provides an anvil surface which supports the crown (25) of the staple during the forming operation. The driver (6) has an inverted U-shaped notch (45a) formed therein which defines parallel side edges (46, 47) to bend the staple legs (26, 29) about the anvil and a transverse edge joining the side edges and adapted to contact the crown of the staple near the end of the forming operation. In the anvil and driver assembly of the present invention, the clearance between the parallel bending edges (51, 52) of the driver and the adjacent anvil edges is greater than the transverse dimension of the staple wire. The anvil surface (18a) of the anvil is concave and the crown contacting edge of the driver is so configured as to impart a temporary bow in the staple crown near the bottom of the driver stroke, which bow is of such dimension as to preclude plastic deformation of the crown. This produces a more generous bend and a slight over-bend at the junctures of the staple legs and the crown such that when the crown is released by the driver and returns to its rectilinear state, this action of the crown will compensate for the natural spring-back properties of the material from which the staple is made at the above noted junctures, consistantly producing the desired final formed configuration of the staple.

Granted: 1993-02-17
Abstract: There is a ventilation grille for an air flow directed from the outside inwards, in which an outer and a central row 6, 8 of slats 7, 9 are staggered in relation to one another, in which the slats 11 of an inner row 10 lie opposite the slats 7 of the outer row 6, and in which the cross-section of the slats 11, 9 of the inner and of the central row 10, 8 has the shape of a V. In this connection, it is desirable that water which passes through the outer slats and is also not removed by the central and inner slats, is nevertheless removed from the ventilation grille. This is achieved by each central slat 9 having, on the V-point 16, a web 14 which projects inwards between two associated inner slats 11 and bears a channel 15 which is open towards the outside and extends parallel to the slats 7, 9, 11 transversely across the ventilation grille. The water which, in the air flow, passes through between the central slat and the adjacent outer slat, passes, guided by the web, into the inner channel which effects the carrying off of this water. <IMAGE>
