A storage system for storing a plurality of fluids or other goods has a plurality of containers adapted to fit within a receptacle. Each of the containers has an inner sidewall, an outer sidewall, and a top sidewall having a spout sealable with a cap such that the container contains the fluid or other goods when the cap is engaged with the spout. The plurality of containers are shaped such that the containers are stackable or nestable within the receptacle such that the containers tessellate, the inner sidewalls of the containers abutting each other, and the outer sidewalls abutting the inner surface of the receptacle, completely filling substantially all of the receptacle.

A tool is provided for use in removing pliable surface compounds from a container and efficiently transferring the compound to a tray or the like. The tool comprises a handle having a longitudinal axis and having first and second ends. The tool also includes a blade secured to the first end of the handle and having first and second adjacent sections. The first section of the blade defines a generally planar controlling section and the second section of the blade defines a generally planar working section, wherein the plane of the second section extends at an acute angle relative to the plane of the first section. The second section defines a contoured edge of predetermined curvature corresponding to the curvature of the container such that the blade can be used to remove surface compounds from the container.

The present invention relates to a method of and an apparatus for forming a thin metal film of copper, silver, or the like on a surface of a semiconductor or another substrate. A method of forming a thin metal film, comprises preparing a dispersed liquid having a metal-containing organic compound dispersed in a predetermined solvent, coating the dispersed liquid on a surface of a substrate and evaporating the solvent to form a coating layer, and applying an energy beam to the coating layer to decompose away an organic substance contained in the coating layer in an area irradiated with the energy beam and bond metal contained in the coating layer.According to the present invention, it is possible to form a thin metal film of good quality efficiently and stably. The thin metal film used as metal interconnects in highly integrated semiconductor circuits contributes to the progress of a process of fabricating semiconductor devices.

The present invention relates to a novel one step process for preparing cross-linked poly(allylamine) polymers or salts thereof using the novel cross-linking agent of Formula (IV).This invention also relates to the compound of Formula (IV) as well as to a process to obtain it. The cross-linked poly(allylamine) polymers of the invention are useful in medicine as substrate-binding polymers.

A cutting tool designed to easily and efficiently remove a hair weave. The tool has a main body including a fully integrated handle, central portion and slide portion. The central portion has a top edge and the slide portion has a guiding edge and a pointed tip. The main body houses a blade which is partially enclosed by the central portion of the main body and exposed along a sharpened edge along the top edge of the central portion. The sharpened edge of the blade extends into the guide edge of the slide. The blade is designed to cut the thread of a hair weave in order to remove it from the existing hair.

The invention refers to a device and a method for cleaning a gas containing particulate impurities. The device includes a main separator having an inlet for the gas, an outlet for the gas and a rotating member provided between the inlet and the outlet. The rotating member is adapted to bring the gas to rotate for separating by means of centrifugal forces a main amount of the particulate impurities from the gas, wherein a rest amount of the particulate impurities remains in the gas. The device also includes an additional separator adapted to separate substantially the whole rest amount. The additional separator includes an electrostatic filter.

A locking device for quarter turn valves avoids the inadvertent, unauthorized or careless manipulation of quarter turn valves from a desired position thereby minimizing, if not eliminating, the likelihood for damage or injury in an industrial or other setting as a result of the unauthorized opening / closing of the valve. The locking device includes a shroud which is adapted to be placed over the upper end of the stem and adjacent portion of the handle on the valve. The shroud has a capping portion which securely engages a mounting pad of the valve and an upwardly extending channel designed to at least partially surround a portion of the handle. A hole is provided in the channel and aligns with a hole in an adjacent portion of the handle when the shroud is placed on the valve. As such, the post of a lock is easily inserted through the aligned holes. The locking device according to this invention advantageously prevents the unauthorized manipulation of the handle and the resulting rotation of the valve member to / from the open / closed positions.

[Object] When rare earth magnets are plated, components of the rare earth magnets are dissolved in the plating solution, causing plating defects. Thus, an easy method for removing rare earth impurities has been necessary.[Means for Solution] A nickel-electroplating solution containing rare earth impurities is kept at 60° C. or higher for a predetermined period of time to precipitate rare earth impurities for separation by sedimentation or filtration. Rare earth impurities can be precipitated further efficiently by adding precipitate to the nickel-electroplating solution, or by concentrating the nickel-electroplating solution by heating.
