Abstract: A nonionic surfactant having cyclic 1,3-dioxane and/or 1,3-dioxolane functionality which is irreversibly splittable by lowering the pH of its aqueous solution is useful in various processes requiring the removal of emulsified hydrophobic contaminants or other hydrophobic materials from an aqueous stream. After splitting of the surfactant into its component aldehyde and polyol, the hydrophobic components phase-separate and can be removed from the aqueous stream by routine means.

Abstract: The invention provides a process for synthesizing alkanolamines and/or alkyleneamines by reacting either an alkane, an alkene, or both with a source of oxygen and a source of nitrogen and, optionally, additional hydrogen to convert the alkane and/or alkene by selective partial oxidative amination to at least one of the desired end products. The invention further provides a regenerable catalyst for use in synthesizing alkanolamines and/or alkyleneamines by selective partial oxidative amination of alkanes and/or alkenes.

Abstract: A vending machine face has a number of modules that are mechanically fastened to an underlying frame. These modules can be easily removed and replaced in the field so that the appearance of a vending machine can be changed with promotions, new interactive pieces can be added, the location of the vend selection buttons can be changed, recessed display compartments can be used and/or different light boxes with various graphics can be inserted and removed. This arrangement will provide for the ability to completely change the appearance of the vending machine on site. The vending machine can be customized for specific account location and can be switched from one promotion to another relatively easily. A frame for holding the modules is provided. The frame and modules be a door for the vending machine. This door can be flat or have a contoured, undulating outer face. Also, the door can be rectangular or have other shapes as desired.

Abstract: The present invention relates to improved reductive amination processes whereby monoethanolamine and ammonia are reacted in the presence of hydrogen and various reductive amination catalysts to yield high selectivity to acyclic products such as aminoethylethanolamine, while reducing the production of cyclic products such as piperazine. When the process of the present invention is carried out in the presence of reductive amination catalyst containing metals such as nickel or nickel-rhenium on transitional alumina carriers, productivity and selectivity to the desired products is increased. Alternatively, the process may be carried out in the presence of hydrotalcite-like or takovite-like catalysts which have been enhanced by the use of promoters to achieve the desired results.

Abstract: A vending machine is provided with a cabinet having a plurality of slanted shelves. These shelves will feed to an elevator which can be located in the center of the vending machine, to one side of the vending machine or at the rear of the vending machine. Packaged beverages will feed by gravity from the shelves to the elevator and then be delivered to the delivery port in the face of the cabinet. This delivery port will be at a convenient height for the consumer. The shelves in the cabinet are readily reconfigurable such that their positioning within the cabinet can be easily altered. Gravity release devices are provided on each shelf for discharging the packaged beverages to the elevator. These gravity release devices are powered by an activation device on the elevator. Thus, electrical connections or the like are unnecessary for the individual shelves.

Abstract: An apparatus for use in respiratory therapy procedures in the field of medicine. The apparatus of the invention converts liquid medication into an aerosol mist comprising sub-micron size particles and provides for delivery of this mist with such high efficiency that up to 40% of the original dose of medication placed in the nebulizer will be deposited in the patient's lungs.

Abstract: The present invention relates to improved reductive amination catalysts useful in the production of alkyleneamine compositions having lower levels of cyclic components. Although typical reductive amination catalysts contain nickel or nickel-rhenium on carriers such as alumina, silica, silica-alumina and silica-titania, it has been discovered that by using carriers selected from the transitional aluminas, improvements are obtained in both selectivity to acyclic products and in activity of the catalysts.

Abstract: A novel security seal which cannot be removed without destroying or defacing the seal, thereby rendering tampering detectable. The novel seal comprises a strap having a tongue end, a locking head at the other end, with a key and stop plate disposed therebetween. To engage the seal, the tongue is looped around and inserted through the locking head. As it is pulled tight, the key engages a lock plate inside the head. When the key is fully engaged, the stop plate abuts the head, preventing undetected tampering or withdrawal of the tongue. In locked position, the tongue remains exposed and is therefore a convenient location for coded information.
