Patent number: 5034421Abstract: A spun product from a combination of a saccharide and a hydrophobic ingredient is hydrophilic with low concentrations of such ingredient but becomes increasingly hydrophobic as the concentration of the hydrophobic ingredient is increased, although the end product nevertheless acts hydrophilically when the water temperature is elevated. Larger ratios of hydrophobic substance-to-saccharide yields a spun fibrous product that has increased stability. Similar stabilization can be attained by adding either beeswax or a petrolatum to the saccharide either in the presence of or absence of a separate active ingredient. Examples are given for masking the taste of unpalatable medicaments or other ingestible substances. Delayed release burn or wound dressings are also described. Control with beeswax can also provide a time release tablet or the like when swallowed.Type: GrantFiled: March 20, 1989Date of Patent: July 23, 1991Assignee: Fuisz Pharmaceutical Ltd.Inventor: Richard C.

Patent number: 4911952Abstract: Chemical biological agents to be encapsulated are blended into an aqueous dispersion of an unmodified starch comprising about 5% to about 25% by weight amylose. The dispersion, having an initial starch solids content of about 20% by weight, is characterized by completely disrupted starch granules and completely disassociated amylose molecules that are not significantly depolymerized. Subsequent drying is accomplished by reassociation of the amylose molecules which converts the dispersion into a protective matrix and binds the agents within the interstices of the reassociating starch chains. Rate of release of agents to the environment can be altered by varying the proportion of amylose in the starch. Encapsulation of biologically active compositions provides protection against degradative environmental conditions, improves safety in handling, and slows the release of such compounds to the surrounding medium.Type: GrantFiled: July 10, 1987Date of Patent: March 27, 1990Assignee: The United States of America as represented by the Secretary of AgricultureInventors: William M.

Patent number: 4861586Abstract: A prefabricated animal bait containing a carrier substance and a pharmaceutically active substance, for example, a vaccine against rabies. The carrier substance contains a fat component and an additive to stabilize the shape retention of the bait, with both components being selected in such a manner that the mixture is pasty for processing and does not break in the temperature range in which it will be used. The bait is produced in such a manner that, in a deep-drawn mold, the carrier substance completely surrounds, and envelopes a pre-assembled unit of the active substance so that the bait merely needs to be pressed out of this carrier foil when it is to be used. Economical industrial production of prefabricated bait in a simple manner, easily and optimally adaptable to the respective animal species and its habitat with respect to temperature and moisture is provided. A particular simlification results from the use of fish meal as the additive since it simultaneously acts as a lure.Type: GrantFiled: April 3, 1987Date of Patent: August 29, 1989Assignee: Hartmut KlockeInventors: Lothar Schneider, Irma Schneider
