Abstract: Various techniques and apparatus permit fabrication of superconductive circuits. A superconducting integrated circuit comprising a superconducting stud via, a kinetic inductor, and a capacitor may be formed. Forming a superconducting stud via in a superconducting integrated circuit may include masking with a hard mask and masking with a soft mask. Forming a superconducting stud via in a superconducting integrated circuit may include depositing a dielectric etch stop layer. Interlayer misalignment in the fabrication of a superconducting integrated circuit may be measured by an electrical vernier. Interlayer misalignment in the fabrication of a superconducting integrated circuit may be measured by a chain of electrical verniers and a Wheatstone bridge. A superconducting integrated circuit with three or more metal layers may include an enclosed, matched, on-chip transmission line. A metal wiring layer in a superconducting integrated circuit may be encapsulated.

Abstract: An illuminated artificial floral arrangement is provided which includes a container and a stem support member within the container with an electrical terminal block being mounted on the stem support. At least one artificial flower having a stem extending into the support member extends above the container and includes at least one low voltage lamp mounted within the center of the flower. Electrical leads are wound about the stem and connect the low voltage lamp to the terminal block. A low voltage transformer is provided externally of the container and electrical leads connect the terminal block to the transformer, with the transformer having means for connection to a standard electrical outlet.

Abstract: A low voltage lighting system is provided which comprises at least one stepping stone, and, preferably, a series of stepping stones, with each stepping stone having at least one recessed channel in the upper face thereof, and a light source removably inserted within the recessed channel. The light source comprises a flexible, substantially transparent tube and low voltage lights within the tube. Means are disclosed for connecting the light source to a power source in a selective or predetermined manner.

Abstract: A recirculating oven in which air and oxidized gases from a burner tube are directed to evaporation zone outlets at the bottom of the oven and curing zone outlets at the top and fed into a pair of wire work chambers, the gas streams mixing between the zones and return with volatile substances through a return duct to a burner mounted in the upper portion of the burner tube. The burner tube is mounted within a burner tube housing partitioned so that the volatile fumes returning to the burner are maintained separately from the oxidized gases and air exiting from the burner tube. The burner is electrically energized and has a cylindrical housing supporting a number of radial vanes supported between spaced baffle plates, the vanes imparting a vortex pattern to the gases entering holes in the housing periphery. A support plate on the top of the housing carries two high temperature ceramic igniter heater elements surrounded by a multiplicity of resistance type electrical heating elements.

Abstract: A recirculating oven having dual air plenum chambers each controlled by an individual blower receiving air and oxidized gases from a burner tube intermediate the plenums. The gases leaving the burner tube are drawn by the blowers into the respective plenum and enter a pair of evaporation zone modules at the bottom of the plenums and a curing zone module at the top are fed into a pair of wire work chambers, both air streams mixing between the zones and return with volatile fumes through a return module to a burner mounted in the upper portion of the burner tube which receives the mixture in a swirling fashion from a vortex generator between the tube and burner. The burner tube is mounted within a burner tube housing partitioned so that the volatile fumes returning to the burner are maintained separately from the oxidized gases and air exiting from the burner tube.

Abstract: A socket apparatus for light tubes which normally extend downwardly a substantial distance from a fixture and in which the socket apparatus is swingably mounted relative to the fixture so that the light tubes may be plumb regardless of the attitude of the fixture.
