Abstract: An artificial surface active soft plastic lure (16) includes emulsifiers so that the plastic lure (16) reacts in the presence of water and loses a measurable portion of its mass. Fish attractants and stimulants (12) are added to the surface active soft plastic lure (16) so that as the lure (16) reacts, fish attractants and stimulants (12) are actually released into the water for sensing by fish. The emulsifiers are selected from a group of chemicals including nonionic, amphoteric, alkanolamide, sorbitan monooleates, fatty acids, sulfonates, fatty esters, phosphate esters, amines, anionic, cationic, monostearates, sorbitan tristearates, and sorbitan trioleates. Preferred fish attractants include dehydrated protein and amino acids, in particular amino acids which are water soluble and alkaline or neutral substances having a pH of approximately 7-8. In the preferred embodiments, the amino acids are selected from a group including betaine, glycine, glutamic acid, proline, taurine and valine.

Abstract: Use of calcium taurate as an antihypertensive agent and dietary supplement. The compound is prepared by reacting taurine and calcium in a 2:1 molar ratio. The resulting mixture is diluted with alcohol and the remaining clear filtrate is crystallized. Calcium taurate is taken orally as nutritional supplement or antihypertensive agent, and can be used as an adjuvant to conventional antihypertensive drugs.
Abstract: The present invention provides water-soluble, extended-release chemical formulations, in tablet form, for urine pretreatment, that require minimal, if any, use of a binder component, yet are non-dusting, pliable, structurally strong, and not weakened by exposure to aqueous streams. The present invention also provides a simple and reliable method for controlled dispensing of such tableted formulations into a liquid stream that is particularly advantageous for use in micro-gravity environments, such as spacecraft urinal systems.

Abstract: Aqueous dispersions of 2-(4-thiazolyl)-benzimidazole (TBZ), alone or in combination with 1,2-dibromo-2,4-dicyanobutane (DBDCB), and processes for making the same, are disclosed. These processes generally comprise mixing a xanthan gum with water, adding TBZ and mixing until uniform. DBDCB dispersions are prepared by mixing xanthan gum with water, adding DBDCB, maintaining the mixture at a temperature below about 40.degree. C., grinding the mixture and mixing until uniform. The TBZ and DBDCB dispersions are then blended to prepare a dispersion containing both active ingredients. A method for inhibiting microbial growth utilizing these dispersions is also claimed.

Abstract: A delivery mechanism and device for the passive periodic release of a drug or an active ingredient which avoids the need for external power sources and/or electronic controllers. By taking advantage of oscillating chemical systems, one can change the state, i.e. the pH, of a solution, a drug, enhancer or solubilizer resulting in oscillating the ability of an active ingredient to be delivered transdermally. The pH of a solution can be oscillated over a range of pH values from 2 to 10 by the reduction and oxidation (redox) reactions of salts, such as permanganates, iodates, sulfates, chlorates, or bromates. Upon activation, the delivery system conditions begin to oscillate and with it, the delivery of the active agent oscillates.
