Abstract: A child resistant package which includes a container having an open end and single or multiple threads on the external surface of the container adjacent the upper end. A closure having a peripheral skirt has an inner surface formed with single or multiple threads corresponding in number to the threads on the container for engaging the threads on the container. A deflectable release element is formed integrally on the container. The release element includes an integral axially deflectable lug extending upwardly toward the open end of the container. The closure has at least one locking lug on the skirt of the closure, the number of locking lugs preferably corresponding to the number of threads on the container and closure. The deflectable lug on the deflectable release element normally extends upwardly for engagement with the locking lug such that when the release element is pressed radially inwardly, the lug is disengaged from engagement with a locking lug and the closure can be removed by unthreading the closure from the container. When the closure is reapplied minimal torque is required due to the axial deflection of the deflectable lug and one of the locking lugs on the closure moves past the lug.  In a preferred form of the child resistant package, the deflectable release element and container include interengaging stops to limit the deflection on the release element.

Abstract: A scraper for removing deposits from the exterior of a tubular member includes elements defining an outer jacket which has an inwardly open circumferential recess and two aligned axial openings, and a scraper element in the form of an elongate resilient wire bent to define a series of integral, concatenated, resilient segments, each pair of adjacent segments being connected through a bend or geniculation. All geniculations are received within the recess, and each segment of wire extends generally along a chord of the aligned axial openings. The positions of the chords are distributed around the circumference of the axial openings such that, in order for the tubular member to be accommodated through the aligned openings, the various segments must be deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member, and causes it to clean the tubular member as the scraper moves axially.

Abstract: L'invention se rapporte à un procédé et à un appareil permettant d'utiliser l'énergie d'ultrasons avec un système de stérilisation de l'eau par ultraviolet. Un ensemble transducteur d'ultrasons (36) est disposé dans une chambre de stérilisation ou autour de l'extrémité de ladite chambre de manière à produire une énergie ultrasonore. Les vibrations ultrasonores sont appliquées automatiquement, de façon régulière et intermittente, pour nettoyer les composants au sein de la chambre de stérilisation et interrompre le processus chimique et physique qui provoque l'entartrage dû aux matières minérales et organiques dissoutes dans l'eau. Les vibrations ultrasonores provoquent une action de nettoyage préventive en raison de l'effet de canalisation et de brassage de l'eau. Cette action de nettoyage réel découle également des actions de cavitation et de balayage. L'action de balayage est obtenue par une modulation de fréquence qui, en créant des points chauds et des points froids variables au sein de la chambre de stérilisation, permet le nettoyage uniforme d'un tube de quartz (26) enveloppant une lampe (16) émettrice de rayons ultraviolets dans la chambre de stérilisation. Les vibrations ultrasonores ont également une action microbicide.

Granted: 2004-11-23
Abstract: A dispenser for mixing foam precursor chemicals and dispensing the foamable mixture includes a first module (28) containing shutoff valves (42, 44) and a second module (30) containing a dispensing valve assembly (54). The dispensing valve (54) assembly includes a valve body (82) of a self-lubricating material and a valuing rod (56) which is reciprocatingly retracted in a valve passage (84) of the valve body (82) to uncover orifices (86, 88) which supply the precursor fluids into the valve passage (84), from which the mixed chemicals are dispensed. The dispensing valve (54) assembly includes a die spring (94) which urges a washer (90) to compress the valve body (82) along its axis to help prevent cold flow of the valve body away from the valuing rod (56). The valuing rod is scraped by inner surfaces of the hole (92) in the washer (90) through which the valuing rod (56) is retracted and extended. The die spring (94) is preloaded and retained by a load cylinder (96) which is fixed in the bore (52) in the second housing (50) which contains the dispensing valve (54). An end portion of the load cylinder (96) extends from the bore (52) and carries a thrust ring (180) which engages grooves (184) in the first and second housings (32, 50) for preventi ng relative movement between the two modules (28, 30) alongthe axis of the bore (52). A cap (72) secured within the dispensing end of the bore (52) forms an annular solvent receiving chamber (190) surrounding an end portion of the valuing rod (56). The valuing rod tip (186 ) is rounded and is exposed to the annular chamber (190) when the valuing rod (56) is in a non-dispensing position, so that solvent flowing into the annular chamber (190) flows outwardly over the tip (186) to clean foam chemicals therefrom. The cap outer face (198) and ro d tip (186) are coated with a release material such as TFE.

Abstract: This invention concerns a process for processing at least one coded-binary audio flux organized into frames created from digital audio signals which were coded by subjecting them first to a transform from the time domain into the frequency domain in order to calculate transform coefficients then to a quantification and coding stage of the said transform coefficients according to a set of quantifiers, the said set being determined from a set of values extracted from the said signals, values that make up selection parameters of the said set of quantifiers, the said parameters also being present in the said frames. It is characterized in that it includes a partial decoding stage consisting of decoding then dequantifying the transform coefficients produced by the coding based on a set of quantifiers determined from the said selection parameters contained in the said frames of the coded binary audio flux or of each coded binary audio flux, and subjecting the said partially decoded frames to the said processing in the frequency domain, then making the frames thus processed available for use in a later utilisation step.
