The fries and condiment holder is a combination of two open containers. The larger of the two open containers provides the user with a place to store a food item found at fast food restaurants such as French fries. The smaller of the two open containers is attached to the larger container by a nontoxic adhesive because the present invention makes contact with edible food. The smaller container provides the user with a place to store a condiment. The smaller container is also collapsible and can be flushed into larger container. The user obtains the present invention with the food item in the larger container and with the small container collapse. The user can choose to expand and fill the smaller container with a condiment if the user wants to dip his/her food item in the condiment.

Fries and condiment holder

A bulk amorphous metal magnetic component has a plurality of laminations of ferromagnetic amorphous metal strips adhered together to form a generally three-dimensional part having the shape of a polyhedron. The component is formed by stamping, stacking and bonding. The bulk amorphous metal magnetic component may include an arcuate surface, and an implementation may include two arcuate surfaces that are disposed opposite each other. The magnetic component may be operable at frequencies ranging from between approximately 50 Hz and 20,000 Hz. When the component is excited at an excitation frequency 'f' to a peak induction level B, it may exhibit a core-loss less than 'L' wherein L is given by the formula L=0.0074 f (B)+0.000282 f(B), said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.

A bulk amorphous metal inductive device includes a magnetic core having at least one low-loss bulk ferromagnetic amorphous metal magnetic component forming a magnetic circuit having an air therein. The component has a plurality of similarly shaped layers of amorphous metal strips bonded together to form a polyhedrally shaped part. The device has one or more electrical windings and is easily customized for specialized magnetic applications, e.g. for use as a transformer or inductor in power conditioning electronic circuitry employing switch-mode circuit topologies and switching frequencies ranging from 1 kHz to 200 kHz or more. The low core losses of the device, e.g. a loss of at most about 12 W/kg when excited at a frequency of 5 kHz to a peak induction level of 0.3 T, make it especially useful at frequencies of 1 kHz or more.

A selective etching process cuts shapes from amorphous metal strip feedstock. The etching process comprises depositing a chemically resistant material to one side of the strip in a pattern that defines the requisite shape, mating the metal strip with a carrier strip, exposing at least one side of the metal strip to an etching agent to selectively etch the desired shape, and separating the shape from the strip feedstock. A plurality of layers of the shapes is assembled by adhesive lamination to form a generally polyhedrally shaped bulk amorphous metal magnetic component useful in high efficiency electric motors and inductive devices. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite to each other. The magnetic component is operable at frequencies ranging from about 50 Hz to about 20,000 Hz. When the component is operated at an excitation frequency 'f' to a peak induction level B, the component exhibits a core-loss less than about 'L' wherein L is given by the formula L=0.005 f(B)+0.000012 f(B), said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better than those of silicon-steel components operated over the same frequency range.
