Patent number: 4241149Abstract: An electrolytic cell wherein one of the elements is comprised of a canal clathrate complex of benzophenone and a polyiodide salt of a cation from a group consisting of potassium (K.sup.+), sodium (Na.sup.+), cesium (Cs.sup.+), lithium (Li.sup.+), ammonium (NH.sub.4.sup.+), rubidium (Rb.sup.+) and tetraalkylammonium (R.sub.4 N.sup.+ where R is an alkyl group of less than five carbons). This complex functions through its tunnel-like dispositions of the cations, having certain unfilled sites and certain other sites occupied by the CHCl.sub.3 molecule, as a solid fast ion conductor. The same composition, again apparently because of the canal clathrate complex crystal structure, is adapted, by virtue of its electronic conductivity to function as an electrode in an electrolytic cell.Type: GrantFiled: July 20, 1979Date of Patent: December 23, 1980Assignee: Temple UniversityInventors: Mortimer M.

Patent number: 4239481Abstract: A vortex burner includes a first feed pipe and a second feed pipe disposed within the first feed pipe. A first set of gas distribution tubes extends from an end of the first feed pipe and extends towards a radiant cup portion of the vortex burner. Also, a second set of gas distribution tubes extends from the second feed pipe also toward the radiant cup portion of the vortex burner. A first fuel gas is capable of flowing through a portion of the first feed pipe not occupied by the second feed pipe, i.e. an annulus area of space, and through the associated first set of gas distribution tubes. A second fuel gas, of either a higher or lower Wobbe index than the first fuel gas is capable of flowing through the second feed pipe and its associated second set of gas distribution tubes. Thus, the vortex burner is capable of burning either high or low Wobbe fuel gases. The first and second fuel pipes may also be separately disposed within the vortex burner.Type: GrantFiled: June 19, 1978Date of Patent: December 16, 1980Assignee: Selas Corporation of AmericaInventor: Charles W.

Patent number: 4237730Abstract: A fluid velocity measurement system includes a thermal generation means operated for short durations of time and disposed within a conduit suitable for guiding at least a portion of a fluid whose velocity is to be determined. Disposed downstream in the fluid guide means is at least one of a first and second thermal sensing means. The sensing means are spaced from each other. The first and second thermal sensing means are differentially coupled. The time period starting with the thermal generation means being turned on and heating a slug of fluid and extending to the generation of a differential electrical signal from the sensing means detecting the heated slug of fluid is the flight time of the heated slug of fluid.

Patent number: 4230116Abstract: The tubal ligation instrument of the present invention includes structure for ligating anatomical tubes within the human or animal body, and structure for anesthetizing the anatomical tubes being ligated. An example of an anatomical tube is a Fallopian tube. The instrument further includes a structure for grasping the anatomical element. The grasping structure extends through a channel in the instrument housing. Usually the grasping structure is a rod having forceps tongs at one end with a flat surface formed on a side portion of the rod. Consequently, the rod does not occupy the entire housing leaving a channel between the rod and the housing.
