A perspective receptacle charged with liquid and having its mouth portion sealed with an opaque seal member is rotated as-erected at a high speed. Due to this high speed rotation, the air resident in the vicinity of the mouth portion of the receptacle forms an air cavity and descends below the seal member. This descending air cavity is detected from the outside of the receptacle by means of an opt...

This invention is concerned with a machine and/or system as well as a method of operation and an assembly whereby a sweeping unit may be quickly converted into a scrubbing unit and vice versa. The system is capable of operation either in a sweeping mode or a scrubbing mode and is also adaptable to include a vacuum wand assembly when the unit is to be operated in its sweeping mode.

Improved recovery of platinum lost from the catalyst gauze in a nitric acid plant is obtained by using palladium containing recovery gauzes configured to enhance the mass transfer characteristics of the system.

The adsorbent for separation and recovery of CO is prepared by contacting an alumina or silica-alumina carrier with a mixed solution or dispersion of a cupric salt and a reducing agent in a solvent and, then, removing the solvent. The preferred cupric salt is cupric chloride.

PURPOSE: To provide facility of operation, portability, upper half body supporting means, and the like and make stunt riding possible by constituting a device in such a way as to be propelled by potential and/or kinetic energy during travel and to control a travel direction by inclining a travel face and a frame.
