  • Patent number: 6655537
    Abstract: A support rack for a plastic container having a content in excess of 1.5 gallons of liquid. Two or more support members extend from a wire body section, for engagement with apertures in the plastic container. A connecting section extends between the support members of first sides thereof, and supporting sections extend from second sides thereof for connection to a suspending support member. In one embodiment the support members are U-shaped and in another embodiment they are finger members. The support rack can be connected to the suspending support member in a stationary or swivel manner or can be part of a rolling cart.

  • Patent number: 6459828
    Abstract: An optical switch array has row and column waveguide segments, on a waveguide substrate. Each waveguide segment terminates in a trench positioned in one of two patterns. In the first pattern, the trenches are positioned along the diagonal while in the second pattern, the trenches are positioned in a regular array. The row and column waveguide segments are in fixed relation and generally parallel to the surface of the waveguide substrate. A heater substrate has heaters aligned to the waveguide substrate in accordance with the trenches. A liquid, disposable within the trenches, is responsive to the heaters. The liquid has an index of refraction such that optical transmission from a first selected waveguide segment to a second waveguide segment is determined by presence of the liquid within the trenches.

  • Patent number: 6396972
    Abstract: An optical switching arrangement, preferably an add/drop switch, provides a high degree of flexibility in manipulating optical signals by utilizing switching units that are mirror images of each other. The switching units are toggled between transmissive states and reflective states by the manipulation of index-matching fluid within trenches. In a first set of switching units, the trenches are offset in one direction relative to crosspoints of waveguides through which optical signals are propagated. In the second set of switching units, the trenches are offset in the opposite direction. As a result, the reflection characteristics of the first set of switching units are the mirror image of the reflection characteristics of the second set of switching units. In the preferred add/drop switching application, any one of a number of input ports can be optically coupled to any one of a number of drop ports and any one of a number of add ports can be optically coupled to any one of a number of output ports.

  • 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.
