Abstract: A teat for feeding liquids to animals has fastening means enabling the teat to be fastened to a source of liquid such as pipe or dru m in use to project outwardly from the source. The teat is resilient having an  outer end (9) which is closed apart from a slit (11) in  it which slit is itself normally adapted to be closed to provide a liquid seal. The c losed outer end is preferably concave, coned, cusped or otherwise reentrant. Integral reinforcing means such as webs are located internally on  either side of the slit so that if the end of the teat is squashed or compressed by sucking forces exerted by the animal with components along the direction of slit, the reinforcing means causes the slit to be stretched open, thereby allowing liquid to flow out of it in use. The pulling or stretching action allows an acceptable flow r ate from a comparatively small slit which is less prone to tear than a large split. A lso a wall-stiffening web is provided, preferably as a t ransverse web (101) integral with the reinforcing means webs, extending from at or nea r the slit towards the inlet end of the teat, to provide  internal stiffening, and acting in conjunction with the resilients to hold the slit c losed when no sucking is occuring.

Ces latex sont à base de copolymères d'acétate de vinyle et d'éthylène et peuvent renfermer facultativement un comonomère, comme l'acrylate ou le méthacrylate d'alkyle. Les peintures formulées à partir de ces latex, sans solvants coalescents, ne renferment pratiquement pas de matières insolubles; les particules de résine dans l'émulsion ont une taille de 0,2 à 0,35 micron, moyenne pondérée déterminée par fractionnement capillaire hydrodynamique. En d'autres termes, les particules de copolymère sont caractérisées par le fait qu'un petit pourcentage, jusqu'à 5 % environ du nombre total de particules dans le latex, ont une taille moyenne supérieure à 0,35 micron, avec un petit pourcentage possédant une taille inférieure à environ 0,2 micron. De plus, les particules de résine sont pratiquement monodispersées. L'éthylène remplace l'acrylate classique comme monomère à basse Tg, ce qui donne des particules de résine possédant une Tg de -5 à 8 °C. Le procédé amélioré pour la production d'émulsion ou de latex comprend une composante importante, à savoir la formation d'un latex-semence, suivie de la polymérisation des monomères en présence de la semence, les monomères étant introduits sur une certaine période de temps.

Granted: 2007-10-09
Abstract: There is provided a method of effecting mass analysis on an ion stream, the method comprising passing the ion stream through a first mass resolving spectrometer, to select parent ions having a first desired mass -to--charge ratio. The parent ions are them subject to collision-induced dissociation (CID) to generate fragment ions, and the fragment ions and any remaining parent ions are trapped; the CID and trapping can be carried out together in a linear ion trap. Periodically pulses of the trapped ions are released into a time of flight (TOF) instrument to determine the mass -to--charge ratio of the ions. The delay between the release of the pulses and the initiation of the push-pull pulses of the TOF instrument are adjusted to maximize the duty cycle efficiency and hence the sensitivity for a selected ions with a desired mass-to-charge ratio. This technique can be used to optimize the performance for a parent ion scan, and MRM scan or a neutral loss scan.
