An apparatus is disclosed for the micro-organism surface sterilization of foods using, a "germicidal" such as light waves (e.g., ultraviolet), and in some cases in combination with (or replaced by) one or more of sound waves and ozone. The surface sterilizer apparatus may include a plurality of germicidal (e.g., ultraviolet) emitters for surface sterilization of foods that are, e.g., rotated in a drum or rotated via a screw auger. Assemblies of emitters for the germicidal may be constructed to be watertight (i.e., withstand a high pressure, heated water spray), and movable relative to the drum or screw conveyor for easy cleaning and maintenance. The apparatus may also include a controller (e.g., programmable logic controller) for controlling the sterilization process so that the apparatus does not endanger personnel nearby, and so that the food is properly sterilized.

A stable, substantially homogeneous, solid block cleaning composition can be made for general purpose cleaning and for cleaning hard surfaces such as floors of varying surface composition. Unique solid block materials contain substantially useful concentrations of liquid acid materials, but are in the form of a stable solid. The acidic solid detergent can be dispensed using a water spray creating a concentrate which can then be diluted in proper ratio to form the use-solution. Such use-solutions may be applied to remove a variety of soils subject to acid cleaning including soils containing water hardness components, inorganic soils, and the like. The acid cleaners can be used alone or in combination with other cleaners in a cleaning protocol for a variety of hospitality, industrial or institutional cleaning locations having a broad spectrum of contaminated soil residue.

An arrangement for the cooling of computer data centers. More particularly, the arrangement eliminates the problems present in the uneven or inadequate cooling of computer racks due to unwanted airflows, which are encountered between so-called hot aisles and cold aisles present in a computer data center. Specifically, this problem is solved through the provision of partitions which, under normal circumstances, prevent the unwanted airflows by standing in a vertical orientation, yet which, in the event of a fire, collapse from the vertical orientation to a horizontal orientation, thereby avoiding interference with water sprays from sprinkler heads, and thus complying with fire codes and ordinances. Moreover, also employed is a method of preventing the unwanted air flows by utilization of the novel arrangement comprising the fire-code-compatible, collapsible partitions.
