A micro flow device for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts. The posts are spaced across the width of an expanded collection chamber region in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, being curved in cross-sections, e.g. circular or tear-drop shaped, and are randomly arranged so as to disrupt streamlined flow. The device is oriented so that its lower surface is aligned at about 45? to the horizontal. Sequestering agents, such as Abs, which are attached to surfaces of the collection region via a hydrophilic coating, preferably a permeable hydrogel containing isocyanate moieties, are highly effective in capturing cells or other targeted biomolecules while the remainder of the liquid sample exits horizontally.

A water pipe includes a pipe body (1), a woven layer (2) sleeved around the pipe body (1), a first joint assembly (3) arranged at one end of the pipe body (1) and secured to the pipe body (1), and a second joint assembly (4) arranged at another end of the pipe body (1) and secured to the pipe body (1); the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. The woven layer (2) is sleeved around the pipe body (1) and is not connected with the pipe body (1), and the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. Bamboo charcoal fibers have the functions of resisting bacteria and removing peculiar smell and can effectively prevent the generation of bacteria on the water pipe and the emission of peculiar smell when the water pipe is used in humid outdoor environments.

A micro flow device (11, 71) for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts (23, 81). The posts are spaced across the width of an expanded collection chamber region (17, 75) in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, being curved in cross-sections, e.g. circular or tear-drop shaped, and are randomly arranged so as to disrupt streamlined flow. The device is oriented so that its lower surface is aligned at about 45? to the horizontal. Sequestering agents, such as Abs, which are attached to surfaces of the collection region via a hydrophilic coating, preferably a permeable hydrogel containing isocyanate moieties, are highly effective in capturing cells or other targeted biomolecules while the remainder of the liquid sample exits horizontally.

A curved plastic faucet contains: a body, an arcuate tube, connector, and a supply head. The body includes a connection member. The arcuate tube includes an inflow segment, an outflow segment, an arc-shaped section extending to circumference length of the inflow segment from the outflow segment, and an arcuate water conduit which has an imaginary arc line being an arcuate section of a circle and a length of the arcuate section is not more than of the circle, wherein a cross section of the arcuate water conduit proximate to the inflow segment is not more than that of the outflow segment, and an outlet is defined adjacent to a lower end of the outflow segment. The connector includes an inlet and at least one stop ring. The supply head includes a guide space and a second screwing portion mating with a first screwing portion.

A flange assembly for supporting a cable has a flange for supporting a cable therein. A flange body has one or more lugs disposed about a circumference of said flange body. A retention ring is dimensioned to fit over the flange body and retain the flange assembly by connecting with the lugs.

A flow passage sealing structure for omitting a process of welding or caulking an orifice plate and a filter plate to an orifice base and a filter base as base materials and allowing further miniaturization, includes a main block (1) including main flow passages (1a, 1b), recessed portions (12, 13) provided in side surfaces of the main block and having female screws in inner peripheral surfaces, thin plates (6, 8) abutting against the bottom surfaces of the recessed portions and having through holes, gasket rings (16, 17) abutting against the thin plates (6, 8), pressing pipelines (20, 21) having large-diameter portions and internal flow passages communicable with the main flow passages (1a, 1b) and abutting against the gasket rings, and fastening screws (22) abutting against the large-diameter portions and pressing the pressing pipelines by being inserted around the outside of the pressing pipelines and screwed into the female screws.

Unique gas cell constructions based on a hollow-core photonic crystal fiber are used, for example, inside a fiber ring laser cavity as an intracavity gas cell. In one embodiment, two simple terminal blocks are coupled to opposite ends of the hollow-core photonic crystal fiber. Each block features a main through-bore with an optical window at one end and an optical fiber chuck fitted at the other end, while a transverse bore intersects the main bore and features a gas fitting for connection to a gas source or vacuum pump. In another embodiment, the hollow-core photonic crystal fiber is contained within an enclosure whose exterior walls are fitted with optical windows and gas ports. Inside the enclosure, fiber clamps supports the ends of the hollow-core photonic crystal fiber at positions adjacent to an in alignment with the optical windows.

This disclosure relates generally to a quick disconnect coupling for connecting a tube to another structure, such as a structure defining a port. The quick disconnect coupling may include a tube including a retention shoulder, a swivel rotatably disposed on the tube, and an adapter defining a bore for receiving a portion of the tube. The swivel may be engageable with the adapter to trap the retention shoulder between the swivel and the adapter. The adapter may be engageable with a receiving structure defining a port and the port may be in fluid communication with a lumen of the tube when the swivel is engaged with the adapter.

An industrial process transmitter includes a main housing, a sensor body, and a flange member. The main housing contains transmitter circuitry and includes a first threaded portion. The sensor body includes a process sensor and a second threaded portion in threaded engagement with the first threaded portion. One of the first and second threaded portions includes a threaded cylindrical projection, and the other includes a threaded cylindrical bore. The flange member is received within a groove of the projection. Movement of the sensor body relative to the housing along an axis of the bore is restricted to an axial distance through engagement between the flange and the first or second threaded portion that includes the threaded cylindrical bore, and engagement between the main housing and the sensor body. Rotation of the sensor body relative to the housing about the axis is limited by the axial distance.

A turbo-molecular pump comprises: a shaft to be rotatably driven by a motor; a pump rotor; multiple bolts penetrating the pump rotor from a pump suction port side to fasten the pump rotor to a pump suction port side end portion of the shaft; and a seal member configured to seal a clearance between fastening surfaces of the pump rotor and the shaft or a clearance between each bolt and the pump rotor.
