Abstract: A test paper, manufactured by impregnating a glass fiber-made paper or cloth with a starch and potassium iodide reagent, liberates iodine on the test paper in such a quantity as to exactly correspond to the peroxide content of an oil or fat coming into contact therewith. Since the liberated iodine easily combines with the ambient starch and turns blue in accordance with the quantity of iodine upon subsequent addition of water, determination of the peroxide value, or consequently the edibility, of the oil or fat can be conveniently effected by determinaton of merely finding the intensity of the color developed on the test paper.

Abstract: A method for determining a volume of red cells in a blood sample. The method includes the steps of flowing along a conduit a predetermined volume of the sample, introducing an agglutinating reagent and a predetermined volume of a dye into the conduit to mix with the sample and agglutinate the red cells, the dye being of known concentration on the introduction thereof, decanting the agglutinated red cells from the conduit, and colorimetrically measuring the concentration of the dye in the conduit, the agglutinating reagent being characterized by a relatively high positive electrical charge and the dye being water soluble and characterized by not penetrating said cells and not forming a precipitate with the agglutinating reagent or with the soluble components of the sample and not lysing the cells or altering the volume of the cells.

Abstract: Apparatus for cleaning incrusted deposits from the regions of coke oven doors between a central refractory sealing plug and a surrounding sealing edge or strip with the use of two pairs of nozzles carried on the upper and lower ends of a frame which can traverse the inner end of the door on which the sealing plug is carried. The frame has a length preferably one-half the height of the door such that the upper nozzles will clean the upper half of the door while the lower nozzles clean the lower half. The nozzles are pivotally carried on the frame such that they can be actuated to clean the horizontally-extending portions of the door between the sealing plug and the sealing strip at the upper and lower extremities of the door.

Abstract: Method for the chromatographic analysis of a technetium-containing mixture of bound, reduced technetium; unbound, reduced technetium; and, free pertechnetate. A portion of the mixture is spotted on a chromatographic adsorbent, preferably cellulose-fiber paper, and is developed with an aqueous salt solution, preferably comprising sodium chloride and/or sodium pyrophosphate. The developed chromatogram has an isolated zone in which the unbound, reduced technetium is located. Simultaneously therewith, a second chromatogram is developed utilizing a suitable liquid organic solvent, preferably comprising a mixture of acetone and acetic acid. The developed chromatogram has an isolated zone in which the free pertechnetate is located. Radioactive measurements are made and the amounts of unbound, reduced technetium and of free pertechnetate are determined as proportions of total technetium. The amount of bound, reduced technetium may then be readily calculated.

Abstract: An organic carbon analyzer system particularly adapted for the continuous analysis of raw sewage of a municipality. A gaseous transport is provided for carrying acidified liquid sewage including dispersed particulate matter through an elongated aeration chamber wherein carbon dioxide evolved from inorganic salts diffuses away from the sewage and into the gas. A second gaseous transport free of carbon dioxide and including an oxidizing agent then carries the sewage into a heated chamber having a tortuous interior surface which provides sufficient retention time to oxidize organic carbonaceous materials of the sewage resulting in a second evolution of carbon dioxide. An analyzer provides a continuous reading of the concentration of the carbon dioxide produced in the heated chamber.

Abstract: An improved tripper beam arrangement for actuating the slats of a slatted top quench car.

Abstract: An arrangement adapting a slatted top to a single-spot quench car. The slats are opened and closed in selected groups.

Abstract: Combination muffler and catalytic converter utilizes an axial flow monolithic catalytic element to treat exhaust gases from an internal combustion engine and partially reduce their sound. The device incorporates a venturi in the exhaust gas inlet path to add secondary air. The efficiency of the venturi is quite high since backpressures introduced downstream of the venturi are kept low by providing an extremely long outlet cone for the venturi which reverses the flow direction while preventing wall separation and turbulence. Sound attenuation is provided upstream of the venturi where the backpressures produced have minimum effect in reducing venturi efficiency.

Abstract: An elongated perforated cylindrical housing sleeve is partitioned at its center thereby dividing the sleeve into a pair of separate equally dimensioned chambers. A pair of deodorizing units are mounted in the housing sleeve each in a corresponding one of the chambers thereof. A pair of cover caps are threadedly coupled to the housing sleeve at corresponding ends thereof for facilitating replacement of deodorizing units in the chambers. The sleeve is mounted on a supporting surface. A cylindrical cover sleeve having a length equal to half the length of the housing sleeve is slidably mounted on the housing sleeve. Thus, the cover sleeve covers one of the chambers of the housing sleeve while freeing the other so that the deodorizing unit in the one of the chambers is preserved while the deodorizing unit in the other of the chambers deodorizes the surrounding area.

Abstract: An apparatus and method for the continuous thermal sterilization of packings on rotating or reciprocating shafts to prevent the entry or exit of microorganisms, wherein the thermal sterilization of the packings results from a flow of steam condensate about the packings, characterized in that at least one part of the steam condensate is circulated in a closed cycle. As a result of circulating in a closed cycle, the required quantity of steam is reduced and energy losses are decreased. The apparatus and method are particularly useful for installations carrying out biological processes.

The heat-resistant jacket is advantageously prestressed when placed within the housing.

Abstract: Heat exchange between a fluid and products in sealed containers is effected by the homogeneous repartition at an adjustable flow rate of a liquid in the course of the successive phases of the heat exchange cycle, by streaming at all points of a large and compact batch of the containers along the walls of each of the containers. The fluid circulates continuously over the containers, in the course of successive phases of the heat treatment, after the temperature of said fluid has been readjusted, within a same heat treatment operation, or regulated from one heat treatment operation to the following one. The pressure, or the vacuum, if necessary for the heat treatment, is regulated independently of the temperature. The apparatus for performing this method has a fluid distributing device comprising at least one perforated plate and a number of perforated divider plates.
