Potentials for Photoelectric Grading Equipment

During the 1971–72 season, certified citrus shipments from Florida totaled 30 million boxes 1/ of fresh fruit and 162 million boxes of fruit in processed form (2)*. Grading of citrus in Florida packinghouses and processing plants requires a large amount of hand labor, at a cost estimated to be in excess of 4. 6 million dollars annually.

Practical Noise Control

Physical damage from acoustic energy is not a new phenomenon. The first recorded event is in Biblical history when Joshua lead seven priests around Jericho seven times blowing trumpets and the people shouted and the walls fell. Ancient mortar and gun battery crews put cotton in their ears to lessen the sound, and this was a type of noise control. Since World War II much concern has been exhibited about hearing loss due to high noise levels in work environments, In order to limit the hearing loss of the average person, the Occupational Safety and Health Act of 1970 specifies the noise exposure of an employee for an eight-hour day shall not exceed 90 dBA. This has resulted in a massive noise control effort in industry. Paper published with permission.

Cooling Towers for Process Industry

In the recent past we have seen a dramatic awakening to the problem of properly managing the waste heat being introduced into our water supplies. What was once considered to be an inexhaustible natural resource is now known to have very finite limitations. The accelerating emission of heated wastes to the environment has triggered an acute concern on the part of the public - the legislators - and industry itself. It is generally recognized that few naturally occurring bodies of water are large enough to absorb the staggering amount of future heat loads which could be imposed upon them and that some alternative method of rejecting large quantities of heat must be utilized.

The Use of Fabric Filters in Air Pollution Control

One of the classic and highly efficient forms of industrial air filtration for particulate dust control is fabric filter baghouse. First used in the 1870–1880’s, they have developed into one of the most versatile, high performance air pollution control devices. These units are now capable of efficiencies in the range of 99.9% on particulate as small as 0.20 of a micron in size. I would like to take just a few moments and trace the evolution of the fabric filter baghouse from its inception to its position today. Paper published with permission.

High Efficiency Can Packaging Lines

A common goal of management, production, and engineering is to obtain and maintain a high efficiency can packaging line. This paper presents the philosophies of one method of obtaining and maintaining production at a high efficiency rating from a high speed can packaging line. This philosophy is being presented as it would be developed for a new can packaging line installation. Paper published with permission.

Energy: Resources and Utilization

It is almost impossible to pick up a newspaper or magazine today without being reminded of our present energy situation which by many is referred to as a “crisis”. Paper published with permission.
