    摘要: The difference in concentration of a selected isotope in two materials is measured by directing beams of the materials toward the inlet of a mass spectrometer. A shutter is positioned in each beam to pass the two beams at predetermined different frequencies. The output signal from the mass spectrometer is applied to two synchronous detectors, each of which receives a reference signal representative of the frequency at which a respective beam is passed to the mass spectrometer. The output signals from the two detectors are compared.

    摘要: Some food pathogens are not well controlled by lethality treatments followed by refrigeration. A food processing facility according to this invention reduces the likelihood that food pathogens will be able to enter the food processing facility, or spread should they be able to enter. The food processing facility is divided into a plurality of area, with different areas having different allowed actions that can be taken on the food product, different rules and/or procedures for persons who are allowed entry, and/or different levels of cleanliness. The food processing facility includes a plurality of separate rooms for processing the food product, each including separate food processing machines, air handling systems, drain systems and/or often-used supplies and tools. Different air pressures within different areas limit the possible movement of airborne food pathogens. Sanitizing stations are placed between various ones of the different areas.

    摘要: Fecal leakage and contamination from the vent opening of an animal carcass during slaughtering and processing is reduced or eliminated by applying a curable adhesive composition to the vent opening and permitting the applied curable composition to cure to form a cured firmly adherent vent seal after de-feathering has been completed or has progressed substantially. The curable sealing compositions are safe in the fully-cured state and do not liberate undesirable materials during curing.

    摘要: A paraffin or mixture of paraffins having from 2 to 5 carbon atoms is oxidatively dehydrogenated in the presence of a cobalt based catalyst composition which has been calcined in the absence of oxygen. The catalyst composition comprises cobalt; phosphorus; at least one promoter selected from the group consisting of zinc, titanium, zirconium, niobium, indium, lead and bismuth; at least one alkali metal and oxygen. The catalyst composition may also contain sulfur and/or a halogen. If the feed to the oxidative dehydrogenation process contains paraffins having more than two carbon atoms, some cracking of such paraffins will also occur at the conditions at which the oxidative dehydrogenation process is carried out.

    摘要: A process and apparatus for removing an impurity from a gas by means of selective absorption of a gas impurity by a suitable absorbent. The absorbent and gas are contacted in a cocurrent flow contacter which is submerged in the absorbent. The flow of the absorbent in the absorber can be induced by means of the dispersion of the gas in the absorbent thereby avoiding the need for pumps or other means to induce circulation. The process and the apparatus can be used for the removal of carbon dioxide from natural gas with the use of salt water, e.g., sea water as the absorbent. The invention is specially useful for removing carbon dioxide from natural gas obtained from a natural gas well located in off shore waters that produces a gas with a high concentration of carbon dioxide as the apparatus can be erected on the ocean floor and use the surrounding sea water as absorbent.
