International Classification:

B32B 3/00

US Classification:

360 9912

Abstract:

A disk drive includes a drive housing and a storage disk rotatably coupled to the drive housing. In one embodiment, the storage disk includes a first substrate, a spaced-apart second substrate, a damping layer and a rigid substrate spacer. The first substrate is formed from a first material having a first composition and the second substrate is formed from a second material having a second composition. The damping layer is positioned at least partially between the first substrate and the second substrate. The rigid substrate spacer is positioned at least partially between the first substrate and the second substrate, and is formed from a third material having a third composition that is different from the first composition and the second composition. In one embodiment, the first composition is different than the second composition. The first substrate has a first thickness and the second substrate has a second thickness that can be different than the second thickness.

Abstract:

Described is a mobile phase fitting having reduced corrosion and erosion. The fitting includes a coupling body, compression screw, compression member and gasket. The coupling body has a threaded bore at one end, a tapered cavity, a narrow bore and a fluid channel. The compression screw has an axial bore to receive a tube and a threaded outer surface in engagement with the threaded bore of the coupling body. The compression member is disposed in the tapered cavity and has an axial opening to pass the tube and a tapered surface to engage a surface of the tapered cavity. The gasket is disposed in the narrow bore and has one surface in contact with the first internal surface and has a parallel surface to receive an end face of the tube. Mobile phase flows along a path that includes the tube, an opening in the gasket and the fluid channel.

International Classification:

G01N 30/02

Abstract:

A heater assembly used in chromatography includes a thermally conductive base having a chamber extending fully through the base with an opening at a first side of the base and at a second side of the base, and a cavity with an opening at the second side of the base. A heater is disposed within the cavity in thermal communication with the base. A thermistor assembly, having a thermistor within a thermally conductive body is disposed within the chamber. The body has a head region with a planar surface. The planar surface of the head region is exposed at the opening of the chamber at the first side of the base for making thermally conductive contact therewith. The thermistor assembly is thermally isolated from the base.

International Classification:

F16L 19/02

Abstract:

Described is a coupling seal that includes a polymeric body having a bore extending from a first end to an internal sealing surface and a fluid channel extending from the internal sealing surface to a second end. The bore is configured to receive a tube having a fluid channel so that an endface of the tube engages the internal sealing surface. The second end of the polymeric body is configured to contact a sealing surface of a coupling body that has a fluid channel extending from the sealing surface. A fluidic seal occurs when the coupling seal is compressed between the endface and the sealing surface. A void between an outer surface of the polymeric body and an inner surface of the coupling body receives the deformation of the coupling seal while under compression to thereby prevent the fluid channel of the tube from being crushed or obstructed.
