The electrical hazard of the future
This paper calls attention to a continuing and growing problem concerning an ever-present electrical hazard that is being swept under the rug. Several miscalculations and lack of understanding of grounding have combined over the past 80 years to set into motion the electrocution of dairy cows, pigs and humans residing in North America from the electrical distribution system. The urge to reduce costs by the utility companies has resulted in the lack of maintenance of the electrical distribution system. This combined with an expected increase in peak demand of 16 percent over the next decade is expected to result in an increase in stray current flowing uncontrolled over the earth shocking and killing not only dairy cows and pigs, but humans too.
The hazardous multigrounded neutral distribution system and dangerous stray currents
The multigrounded neutral system is the predominant electrical distribution system used in the United States. It permits an uncontrolled amount of electric current to flow over the earth unrestrained, posing the potential of harm to the public and to animals causing electric shocks and is presumed responsible for undetected electrocutions. To compound the problem of uncontrolled current over the earth, utility practices places harmful current from lightning strokes directly into customers homes. As today's electrical loads continue to escalate, more current is forced into and over the earth. The question electrical engineers and the public must answer is what is the acceptable safe level, if any, of the passage of uncontrolled flow of electrical current over the earth and into our homes, office buildings and industrial facilities. The decisions to "save money" by the adoption of the multigrounded neutral electrical distribution system outweighed the public's safety are disclosed in this paper and the electrical distributions systems that are safe are presented. The history of the development of the multigrounded neutral distribution system is covered. Examples of the dangers associated with the multigrounded neutral distribution system and the ungrounded distribution system are disclosed. The methods of converting these dangerous and hazardous distribution systems into safer systems are presented.
The development of a liquid antihistaminic preparation with sustained release properties.
The relative capacity of several cation exchange resins to adsorb methapyrilene has been determined by an in vitro method. It was demonstrated that methapyrilene adsorbed on sulfonic acid cation exchange resin possessed pharmacological activity approximating that of a solution of methapyrilene hydrochloride as measured by the protection against histamine-induced asthma in the intact guinea pig. It is suggested that the use of ion exchange resins as carriers of drugs in liquid dosage forms may be useful in sustained release preparations.
