Abstract: 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.

Abstract: 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.

Abstract: 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. In one embodiment of the invention circuitry is provided to measure the actual flight time and divide it into a predetermined period of time resulting in a quotient which is proportional to the fluid velocity.

Abstract: The surface of a carbon fiber is treated to improve the strength of its bond with a matrix. The fiber is made an anode by connecting it electrically with the anode current input terminal of an electrolytic treatment bath containing an electrolyte and having a cathode. The fiber is subjected to electrolysis in the bath. The relative distance between the fiber and the cathode in the bath decreases as the distance from the anode current input terminal along the fiber is increased.

Abstract: The present invention relates to a process for preparing a highly tensilized polyester film that has enhanced mechanical properties in both longitudinal and transverse directions. The process involves the simultaneous machine and transverse direction stretching and subsequent heat setting of a film that has already been highly stretched in the machine and transverse directions individually. During the simultaneous stretching process both the temperature and rate of linear movement of the film are controlled.

Abstract: 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. On an outside surface of the instrument housing is an anesthesia receiving means, typically a stopcock. A channel through the stopcock, through which anesthesia may flow, is capable of communicating with the channel between the rod and the housing.
