Abstract: The invention provides a method, system, and device for producing a steady flow of carbon dioxide. In one embodiment, the invention may be used as an attractant for an insect species, particularly a hematophagous insect species.

Abstract: A message delivery device for communication between a sender and a receiver having a container, a cover having a label on it that is easily personalized to a specific sender, and a rolled-up message strip disposed within the container having a time-dependant message. The time-dependant message is read and displayed as the user un-rolls the message. A display system having rows to hold the message delivery devices and a pull-tab for displaying the time-dependant message outside of the container is also disclosed.

Abstract: A microparticle composition for paper making includes finely divided particles of a water insoluble solid such as amorphous sodium aluminosilicate, and having an anionic charge of at least 20 millivolts, and preferably from about 40 to 60 millivolts, and a particle size of less than about 0.1 microns.

Abstract: An aqueous anti-slip coating composition for paper includes 10-50% by weight insoluble silicate particles of 180-300 millimicron average particle size, and 0.5-10% by weight dispersant.

Abstract: In a process for rapidly producing colloidal particles a feedstock of particles less than a micron in size is provided to a stirred media mill, along with ceramic beads less than 100 microns in size. The mill is filled to a volume in excess of 90%, and operated at tip speeds in excess of 20 meters/second with a residence time less than about two minutes; thereby producing particles having an average particle size less than about 0.1 micron from the feedstock.

Abstract: Active or functional materials such as adsorbents, catalysts, defoamers and the like are combined with inert low density particles, preferably hollow microspheres, to provide a functional material of controlled density. This product is introduced into a liquid with a somewhat higher density under agitation for a time sufficient to accomplish the desired function. Then agitation is stopped and the spent product floats to provide easy separation.

Abstract: A pheromonal compound produced by the banded cucumber beetle has been identified as 6,12-dimethylpentadecan-2-one. Both the synthetically prepared racemic compound and the purified natural pheromone elicited responses by banded cucumber males in field tests. By attracting adult beetles to field traps, this compound is a useful tool for the monitoring and controlling of this major agricultural pest.

Abstract: Novel diolefin insect pheromone mimics are used to disrupt the sexual communication between insects when applied to an agricultural area in behaviorally effective amounts as follows: (Z)-1,12-heptadecadiene used for Heliothis zea Boddie; (Z)-15-methyl-1,9-heptadecadiene used for Trogoderma variable; (E)-15-methyl-1,9-heptadecadiene used for Trogoderma glabrum; and (Z,Z)-1,12,14-heptadecatriene used for Amyelois transitella.

Abstract: A self-dressing mounting beam for slicing wafers from ingots of various materials, especially semiconductors, is described. The mounting beam is a composite material comprising an organic polymer, particles of abrasive and hollow microspheres. The ingot is mounted on the beam and sliced using an inside diameter saw. The saw penetrates the mounting beam as well as the ingot, so that the self-dressing feature is realized with each pass of the blade.

Abstract: A pheromonal compound produced by the southern corn rootworm has been identified as 10-methyl-2-tridecanone (10-M-2-T) having the structural formula: ##STR1## The synthetic R-enantiomer of 10-M-2-T demonstrates activity toward the southern corn rootworm comparable to its natural counterpart, whereas the synthetic racemic mixture is characterized by approximately half the activity for a given amount. Related diabroticites such as the western spotted cucumber beetle also respond to the synthetic compounds. By attracting adult beetles to field traps, 10-M-2-T is a useful tool for the monitoring and control of these major agricultural pests.

Abstract: Inorganic chill-proofing and other agents that are used to process stable beer often contain metals such as iron and copper that are soluble in beer or other beverages. A small addition of magnesium silicate added to said chill-proofing agents, particularly silica hydrogel, substantially averts metal contamination in the beer.

Abstract: Treatment agents are described for use in nodularizing cast iron in the production of ductile iron and also useful in deoxidizing steel and desulphurizing cast iron. The agents take the form of a compacted mixture comprising particulate iron, magnesium and calcium, and are distinguished by(a) a magnesium content of 5 to 15% by weight(b) a weight ratio of magnesium to calcium in the range of from 1:1 to 8:1(c) the iron having a purity of at least 95% by weight and a particle size of all less than 0.5 mm and(d) being compacted into a body of density at least 4.3 gm/cm.sup.3.The high density allows the agent to be used effectively by a simple overpour technique.
