Filed: 1990-12-21
Abstract: The needle connector (10') is made with a shielded connector (11') which is slotted to slide over an arm (16) of a Y-site connector (14). A needle (13) within the shielded connector (11') is able to pierce a rubber stopper or seal (17) in the end of the Y-site connector (14). A rotatable ring (12')on the shielded connector (11')has a cam surface (26) at the end edge which locks against the arm (16) of the Y-site connector (14) while biasing the seal (17) of the Y-site connector (14) into sealing engagement with the interior of the shielded connector (11'). The needle (13) may be fixed in place or may be removably mounted in place via a needle hub.

Abstract: On obtient la répartition homogène de fibres de renforcement en titane à surface rugueuse, fines et courtes dans un ciment osseux à base acrylique à usage chirurgical, en ajoutant les fibres sous forme de faisceaux (20) de plusieurs centaines de fibres (30) liées entre elles dans un liant adhésif (50) soluble dans le composant monomère liquide du ciment osseux. Dans un tel procédé, soit les faisceaux de fibres (20) sont préalablement mélangés au composant perlé à base de polymère pulvérulent du ciment osseux, avant l'adjonction du monomère liquide soit le polymère et le liquide sont préalablement mélangés pour former un liquide visqueux et les faisceaux de fibres sont progressivement ajoutés avec brassage dans le liquide visqueux. Dans les deux cas, au fur et à mesure que le liant adhésif (50) se dissout dans le monomère liquide, chacune des fibres (30) se libère et l'opération de brassage permet d'obtenir un mélange homogène des fibres (30) dans la masse du ciment osseux.

Date Oct. 4, 1990.In a method for controlling the current pulse supply to the discharge electrodes of an electrostatic precipitator unit in order to achieve maximum separation of dust from gases conducted between the discharge electrodes and the collecting electrodes of the unit at issue, current pulses (I) with a given pulse current are supplied to the discharge electrodes. The pulse frequency is varied, and instantaneous values (Up, U(I=O), U(I=O+1.6)) corresponding to one another, for the voltage (U) between the discharge electrodes and the collecting electrodes are measured for a number of pulse frequencies. Then, the current pulse supply to the discharge electrodes is set to the pulse frequency at which the highest instantaneous value has been measured.

Abstract: In the outer periphery contact surface (8) of a butterfly disk (3) of a butterfly valve, the sealing area close to a shaft (2), provided for rotating the butterfly disk (3) into its open or closed position, respectively, is formed smaller than other sealing areas of the butterfly disk (3). Thus, when the valve is closed by the butterfly disk (3), the outer periphery contact surface (8) of the butterfly disk (3) starts almost simultaneously contacting a seat ring (5) throughout the periphery because the area of the contact surface (8) is smaller than other sealing areas. Therefore, a reliable sealing effect can be expected for a long time because the butterfly disk (3) is hardly scratched and the seat ring (5) is hardly abraded.

Abstract: A device for screwing screw-caps (2) onto containers (1) has a conveying apparatus (10) for the containers and a plurality of rotating screwing heads (16) assigned thereto. To test the proper tightening of the screw-caps on the containers, markings (22) are arranged on the periphery of the screwing heads and a sensing apparatus (21) is arranged on the line of revolution of the screwing heads. When the screwing heads pass the sensing apparatus, a number of pulses are generated in each case by the markings, the number corresponding to a minimum number in the case of a stationary screwing head and, in contrast, corresponding to a number exceeding this minimum number in the case of a rotating screwing head. By evaluating this comparison, it is possible to determine a tight or loose screw-cap. <IMAGE>
