  • Publication number: 20200397157
    Abstract: A product display for multiple types of products is provided. The product display includes a front wall having a plurality of openings through which can be shown the product portion of a blister pack. Each of the plurality of openings receive a cover of a corresponding type of blister pack. The product display includes a rear wall spaced apart from the front wall. The product display includes a bottom wall connected to the front wall and the rear wall. The product display also includes a pair of side walls spaced apart from each other and extending between the front wall and the rear wall. The product display further includes one or more partition walls disposed between the pair of side walls. The one or more partition walls define a plurality of compartments corresponding to the plurality of openings. Each compartment can hold the product shown in the blister pack extending from the front wall.

  • Patent number: 10386341
    Abstract: Systems and methods for pumping carbon dioxide in a chromatography system include an actuator that receives and compresses carbon dioxide at or above room temperature at a given pressure to put the carbon dioxide in or near supercritical form. This actuator can be a pre-pump disposed on the intake side of a pumping system. Alternatively, this actuator can be a primary actuator in the pumping system. The actuator includes an intake chamber that receives the carbon dioxide and a movable plunger extending into and closely received by the intake chamber. The plunger has a diameter and stroke length adapted to compress the carbon dioxide received by the intake chamber in sufficient volume at the given pressure to put the carbon dioxide in or near supercritical form at or above room temperature. A metered amount of the carbon dioxide in or near supercritical form can then be pumped.

  • Patent number: 9441996
    Abstract: The present disclosure relates to phase detection in multi-phase fluids where two fluid phases can be present in the fluid. Phase detection apparatus and methods are disclosed for determining the phase(s) (e.g., supercritical, liquid, and/or gas) of a fluid in a multi-phase fluid system, such as carbon dioxide based separation and chromatography system.

  • Publication number: 20070049998
    Abstract: A regulated heat source is described that can be applied to a skin lesion, such as pustular-form eruption or localized abscess, in order to accelerate the death of invading bacteria, fungi or viral particles, or to assist in the breakdown of a skin irritant and thereby speed the recovery process.

  • Publication number: 20050147508
    Abstract: Embodiments of the present invention feature a method and apparatus for detecting defects, such as, leaks, component failure and adverse performance. One embodiment of the present apparatus for pumping fluid comprises a pumping chamber having an inlet and an outlet powered by a motor. The motor operates in pumping mode upon receiving a pumping signal. The apparatus further comprises at least one inlet valve in fluid communication with the inlet of the pumping chamber. And, the apparatus comprises a switchable valve in fluid communication with the outlet of the pumping chamber. The switchable valve has a closed position and an open position, and assumes the closed position upon receiving a close signal. A pressure measuring device is in fluid communication with the pumping chamber, between said inlet valve and switchable valve. The pressure measuring device determines a minimal pressure and first threshold pressure at a first time and a second threshold pressure at a second time.

  • Patent number: 5588846
    Abstract: A connector (10) including a PC board (12) which is fastened to a block (30) and presses against an elastomeric electrical component (40). Electrical device (20) includes a circuit trace (23) and printed circuit board (12) includes a circuit trace (13) which both engage a flexible film circuit (42) on the elastomeric electrical connector (40). Wedge member (50) engages a bottom edge (40b) of elastomeric electrical component (40) for biasingly engaging the component (40) and urging the component (40) and flexible circuit (42) towards and against circuit traces (13,23). Additionally, good electrical contact and compliance to planar irregularities are maintained between circuit traces (13,23) and flexible film circuit (42) thereby ensuring good electrical contact therebetween.
