Abstract: Sampler apparatus and method are provided and include both closed and open tube samplers, and selector valve operable to select therebetween for sample supply to automated sample analysis apparatus. A shear valve divides the samples into separate sample quantities for independent sample quantity analysis by multi-channel sample analysis apparatus. A pressure equilibration chamber prevents vacuum build-up in the closed tube sampler to insure the supply of consistent sample quantities therefrom. A source of a pressurized rinse solution is provided; and is operatively connected to the sampler apparatus in such manner as to insure the particularly thorough rinsing and cleansing of all relevant sampler components to remove sample residue therefrom between sampling operations, thereby reducing sample carryover to levels below those of clinical significance.

Abstract: La présente invention utilise la régulation de l'enthalpie spécifique à l'entrée de l'évaporateur par utilisation délibérée de la pression et/ou de la température avant l'étranglement pour obtenir un réglage de la capacité. La capacité est réglée par variation de la différence d'enthalpie du réfrigérant dans l'évaporateur et par modification de l'enthalpie spécifique du réfrigérant avant l'étranglement. En état surcritique, ce réglage peut être assuré par variation de la pression et de la température séparément. Dans un mode de réalisation préféré, cette modulation de l'enthalpie spécifique est effectuée par variation de la pression avant étranglement. Le réfrigérant est refroidi à une température aussi basse qu'il est possible de descendre au moyen du milieu de refroidissement disponible et la pression est régulée pour produire l'enthalpie requise. Dans un autre mode de réalisation, on utilise la modulation de l'enthalpie par variation de la température du réfrigérant avant étranglement, ce qui est effectué par réglage du rejet de chaleur depuis le dispositif.

Abstract: A plastic closure for a container, such as a bottle having an externally threaded neck, has a top wall, an internally threaded sidewall, and a seal comprising outer and inner concentric sealing members that extend downwardly from an inner surface of the top wall. The outer sealing member extends downwardly farther than the inner sealing member and is substantially thicker than the inner sealing member. The outer sealing member is disposed to engage an outer corner of the rim of the neck of the bottle when the closure is threaded onto the bottle, and the inner sealing member is disposed to engage the top of the rim after engagement of the corner with the outer sealing member. The outer sealing member deflects outward slightly, and the inner sealing member deflects upwardly and inwardly. Movement of the top wall of the closure toward the rim is limited by a shoulder between the sealing members, so that when the closure is fully threaded onto the bottle, the inner sealing member is spaced from the inner surface of the top wall of the closure.
