摘要:
An internally plumbed housing for containing fluid purification media especially suitable for the production of ultrapure water. The device may be installed in a system for the production of laboratory grade water or may be used with pressurized feed for the delivery of purified water or other fluids in multiple applications.
摘要:
There is disclosed a system capable of purifying water to a laboratory grade level that uses redox media, high energy catalytic activated carbon, ultraviolet radiation and high purity ion exchange media in series filtration. The system produces purified water having a specific resistance of at least 18.2 megohm·cm at 25° C. with low organic carbon content. The system is designed to be fabricated on a sufficiently small scale to fit on a lab bench top.

This invention relates to filtration manifolds, filtration assemblies, methods of channeling permeate, and filtration units. Filtration assemblies may include filtration units and filtration manifolds having isolated permeate collection passages. Permeate may be channeled through the isolated permeate collection passages of the filtration manifold during filtration and then output from the manifold.

The invention relates to a magnetic-tape-cassette apparatus having a deck for playing magnetic-tape cassettes, which comprises a loading mechanism including a cassette holder (23) adapted to receive a magnetic-tape cassette (2) and having a holder wall (23e) which guides a cassette wall and which carries laterally projecting pins (23a/b), which pins are guided in lift slots (22b) in a lift slide (22), which slots are inclined relative to the vertical, to lower the cassette holder (23) into a play position and to lift the holder into an eject position, the lift slots (22b) being formed in a lift wall of the lift slide (22), which is movable between a forward and a backward end position, which carries along the cassette holder (23) over a part of its path of movement, and which is movably guided in a parallel first and a second rail (1f, 1n) on the deck plate of the apparatus, in whichthe first rail (1f) is arranged at the location of the lift wall provided with the lift slots (22b) through which the pins (23a/b) extend,the second rail (1n) is arranged underneath the lift slide (22) at a distance (A) from the first rail (1f), which distance is smaller than the width (B) of the magnetic-tape cassette (2) in a direction transverse to the longitudinal direction of the rail,at the location of the second rail (1n) the lift slide (22) has a lift member (22c) having the same inclination as the lift slots (22b), which lift member guides actuating projections (23h, 23k) of the cassette holder (23) in such a manner that at the location of the first (1f) and the second (1n) rail the holder can always be lowered and lifted to the same level.
摘要:
A loading mechanism for an apparatus for recording or reproducing information using an information disc, which mechanism includes guides for the disc edge. The guides include a supporting guide constructed as a support for the disc edge pressed against it and a loading guide constructed as a rotationally drivable transport wheel, which rolls the information disc into and out of the apparatus for the purpose of loading and unloading, respectively, the supporting guide and the loading guide guiding the information disc along a loading path. The loading mechanism has minimal dimensions and enables the information disc to be loaded and unloaded without the surface of the disc being touched. This is achieved by the supporting guide and the loading guide being supported so as to be movable in a loading plane.
摘要:
A test pattern produced by a television signal generator includes picture elements derived at least substantially from helper lines, and vertically adjacent picture elements of substantially different luminance derived at least substantially from the main picture lines, so that the engineer can readily determine by visual inspection whether or not the helper lines are being decoded.
摘要:
This invention relates to filtration assemblies and methods of installing filtration units in filtration assemblies. Filtration assemblies may include first and second end pieces, at least one filtration unit between the first and second end pieces, and at least one alignment rod arrangement. The alignment rod arrangement may extend between the end pieces and align the filtration units and the end pieces.
摘要:
An electrode includes a current collector that is two-dimensional in shape and that contains perforations, and an intermediate layer that is electrically conductive and substantially corrosion-resistant. The intermediate layer is on at least part of a first surface of the current collector, and includes at least one of precious metal, graphitic carbon, a metal nitride, and a metal carbide. A first electrode layer is on the intermediate layer. At least part of the first electrode layer is in at least some perforations of the current collector. The first electrode layer, the intermediate layer, and the current collector are bonded together.
