Abstract: ABSTRACT           An air conditioning installation is combined with a process plant producing hot waste gases. The installation compri? an air handling unit through which fresh air at ambient temperat? is drawn for ducting to a desired location and a heat exchanger through which the hot waste gases pass in spatial flow to fresh air which is thereby heated. This heated fresh air can then be selectively admixed with said ambient temperature fresh air to raise the temperature of the latter if so desired. Waste gas collection ducting extends between the processing plant and an inlet of the heat exchanger. Damper controlled diverting duct means upstream of the inlet to the heat exchanger are also provided for agressing the hot waste gases to a location other than the heat exchanger when a predetermined situation prevails.

Abstract: TRANSFER APPARATUS FOR ENERGY SOURCES      FOR RAILWAY TRACK CIRCUITS                   ABSTRACT OF THE DISCLOSURE    A circuit arrangement for automatically transferring from a main to a standby source for supplying a variable load net-work, such as a railway track circuit comprising first and second monitoring channel apparatus to detect the level of the normal output and load current, respectively.  Source output varies from normal to low level and load current from low to high level as load network varies between relatively no load and heavy load conditions.  The monitor channel detection sig-nals are checked through a logic circuit so that if at least one exceeds a predetermined level indicating the operable condition of the principal source, a registry device is actu-ated to hold the energy supply leads to the load network con-nected to the principal source.  If neither monitor detects an operable condition of the source, the registry device is operated to activate, and transfer the load energy supply leads to, a standby source.

Abstract: LOW PRESSURE SODIUM VAPOR DISCHARGE LAMP               ABSTRACT OF THE DISCLOSURE          A low pressure sodium vapor discharge lamp for generating directional light output, the lamp including a cylindrical discharge tube within a cylindrical outer envelope.        The outer envelope is provided with a diffuse coating which is highly reflective of visible sodium light and which defines a clear aperture on the outer envelope for the directional escape of visible light.        The space between the inner discharge tube and the outer envelope is air filled to provide conductive and convective heat dissipation from the discharge tube.        Sodium condensation takes place in a plurality of spaced reservoirs located in the portion of the discharge tube away from the aperture to keep that portion of the discharge tube facing the aperture clear.        A heater coil is wound around the inner discharge tube to keep it at a desired standby temperature for lamp use on demand.  The lamp filament electrodes are also maintained at standby temperature to improve the illumination profile along the lamp.

Abstract: ABSTRACT OF THE DISCLOSURE          A typical embodiment of the invention combines a novel cellular end fitting for a nuclear reactor fuel assembly with a new design for a fuel rod end cap and a radiation sensing device probe to provide a means for swiftly and accurately distinguishing sound fuel rods from those rods that have developed leaks.  For example, a somewhat thinner than usual fuel rod end cap is accessible through the open cellular structure of the end fitting to permit a hollow metal probe to contact the fuel rod end cap.  This  direct contact excludes most of the water, metal and other shielding materials from the volume between the interior of the fuel rod and the radiation detector, thereby improving the quality of the fuel rod examination.  A bridge and trolley structure for accurately positioning the probe also is described.

Title: Continuous flow system for equalizing the  moisture content of moisture absorbing  products
Inventor: BANKS KENNETH A
IPC: A23N12/00

Granted: 1981-12-29
Abstract: ABSTRACT OF THE DISCLOSURE       A system for controlling the moisture content of moisture absorbing products to achieve a uniform moisture content of the product.  The continuous flow of raw product in chip, diced, extruded or comminuted form initially enters a rotating reel where the product is tumbled and exposed to a high-humidity environment for increasing the moisture content beyond a target value.  The added humidity can be in the form of steam or water spray.  The product continuously flows from the reel wherein moisture is added to a drying reel which reduces the moisture content of the product to specific target values.  Although the original moisture content of raw product entering the system may vary considerably, contact between product during mixing in the moisture adding and drying reels causes the final product to assume uniform and consistent characteristics.  Some products to be processed may require sulphur dioxide treatment and in such instances the addition of sulphur dioxide is included in the process and injected with the steam or water spray.          In addition or alternatively to adding sulphur dioxide other products such as solids, preservatives or nutrients may be added in the steam or water spray.

Abstract: ABSTRACT OF THE DISCLOSURE            Organic material having a normal boiling point in excess of 200°C and a relative volatility with respect to water of at least one is removed from water contaminated therewith.  The process comprises passing a current of vapor, sufficient to vaporize at least a portion of the organic material, through a moving stream of the contam-inated water.  In a preferred embodiment, the process comprises adjusting the pH of the contaiminated water to a level sufficient to prevent substantial dissociation of the organic material.  The contaminated water is then countercurrently contacted with a sufficient vapor flow to vaporize at least a portion of the organic material.          The resulting organic material-containing vapor can be recovered, and the organic material removed.  Illustrative of the process is the removal by air stripping of penta-chlorophenol from waste water contaminated with about 250 parts per billion thereof.     26,692A-F
