  • Publication number: 20210045411
    Abstract: A chew stick for dogs made from strips of beef bladders or esophagus formed into sticks and infused with a solution of water, syrup and gelatin, and humectant, and other ingredients, and colored for appearance, and then heated to dehydrate the chew to about 8% to 14% moisture content to achieve the finished product. The stick may also be coated with a mixture of emulsified meat, such as beef, starch, flavoring extract, oil, and water, to give it an attractive flavoring and toughness as a finished product.

  • Patent number: 5160801
    Abstract: A system for programming the function mode of a munition fuze without supplying electrical power to the fuze includes an arrangement of programmable elements located internally of the munition that are electrically conductive but which remain electrically unpowered until after munition firing, and a programming mechanism located externally of the munition being operable to mechanically program the conductive elements. The programmable elements are a series of concentric bands attached to the interior of the munition casing and spaced from one another along the munition axis and separated from casing wall by an electrically insulating layer. The programming mechanism is a plurality of punch heads aligned with the concentric bands and capable of being actuated such that only selected ones of the punch heads strike the exterior of the munition casing causing an indentation in the casing that penetrates the insulating layer and makes electrical contact with the selected ones of the concentric bands.

  • Patent number: 4892748
    Abstract: A low calorie dog treat is composed of food grade cellulose, a unique binder system holding the matrix, a combination of various color and flavor ingredients, and salt. The product contains only a few calories and can be consumed in large quantities by a dog without contributing to an obesity problem. The product is designed to compete with existing pet treats such as dog jerky, biscuits and bone shaped treats, and it is preferably amenable for use as a very few calorie pet food. The reduced number of calories in the dog treat is related to the fact that the cellulose material is composed primarily of fiber and therefore is not digested by the dog. The gum or binder system used in the formulation is also non-caloric. The product is produced by using existing processing equipment or by adapting such equipment relatively easily to applicants' methods.

  • Patent number: 4849216
    Abstract: A fly attractant composition includes a quantity of poultry protein wherein the poultry protein includes a quantity of at lesat one protein digestive microorganism capable of digesting the protein. This microorganism can either be native to the protein or it can be added as an inoculum. Further the composition contains a quantity of a carbohydrate which is capable of being fermented to yield carbon dioxide as a fermentation product. Additionally the composition contains a quantity of at least one carbohydrate fermentation microorganism which is capable of fermenting the carbohydrate to release carbon dioxide. When water is added to the fly attractant composition to form a fly lure, the carbon dioxide from the fermenting carbohydrate drives off odors from the ingredients which attracts flies to the lure.
