This invention concerns an apparatus for detecting the presence of faults in a translucent container of the kind comprising a scanning zone in which a translucent container is rotated while being repeatedly scanned by a spot beam of light in a direction parallel to the axis of rotation of the container, a light collection apparatus being arranged to receive light from the beam after passing throug...

A process and apparatus are described for collection of gases and particulates which arise during the feeding of an electric furnace, especially in the manufacture of phosphorus. The collection system for the gases and particulates includes novel explosion panels which are employed in an enclosure that contains the gases and particulates, and the use of such panels also in the ductwork and filter ...

A valve assembly including an adjustable nozzle for directing an aimed thin stream of water soluble coolant to a machining cutter. The construction includes an elongated body which houses a valve, the nozzle in adjustable relation, and means for magnetically supporting the assembly upon a machine tool. The nozzle may be fed directly from a pump, or through a foot operated valve in series therewith...

The electrical drive pulse applied to the piezoelectric crystal of an ink jet printer is designed to cause ejection of a single desired ink droplet from the print head and to preclude ejection of unwanted multiple ink droplets. The drive pulse consists of the superposition of two waveforms wherein the first waveform causes ejection of the desired ink droplet and the superimposed second waveform re...

A method of minimizing chlorate formation when brines are decomposed in diaphragm type electrolytic cells which comprises adding brine containing dissolved nickel values periodically to said cell while continuing operation of the cell. The nickel values can be added whenever the chlorate content of the alkali metal hydroxide increases to again minimize chlorate formation.

PURPOSE:To recover formed organic acids and perform a methane-forming treatment efficiently, by a method wherein a mixed sludge liquid obtained by an acid-forming treatment of an organic waste liquid is mixed with cleaning water, and after solid-liquid separation, the separated liquid containing organic acids is subjected to a methane-forming treatment.
