Abstract: ARRANGEMENT FOR DIVERTING LIGHT          Abstract of the Disclosure Light is diverted from one optical conductor to another optical conductor by a suitably oriented non-planar reflecting surface at the junction of the two optical conductors.  The non-planar surface comprises facets arranged so that light incident on one facet from one optical conductor will be reflected at that facet onto an adjacent facet, and at the adjacent facet to the other optical conductor.  The arrangement of facets is such that the Snell's Law condition for total internal reflection at each facet can be satisfied for a wider range of ray directions than is possible for a single planar reflecting surface.  The arrangement is useful for optical backplanes now being proposed for use in computers and telecommunications equipment.                             - i -

Abstract: ABSTRACT      A hole opener for placement in a drill string having a body generally comprising a collar, a triangular mid-section, a triangular shaped pilot and a bull nose.  The collar provides means for attaching the tool body to the drill string.  The triangular mid-section has three longitudinal, radially spaced apart blade members that are parallel to the central axis of the tool body so that the blades can cut into the walls of the bore hole to enlarge the size of the bore hole.  Three annular flow zones span the distance between the blade members so that fluids and cuttings can circulate through the bore hole.  The pilot section also has three longitudinal, radially spaced apart blade members that are parallel to the central axis of the tool body bore and three annular flow zones which span the distance between the blade members of the pilot.  The pilot section is downhole from the mid-section.  The outer diameter of the blades of the pilot section are substantially less than the outer diameter of the blades of the mid-section, thus allowing the hole to be enlarged gradually.  A bull nose downhole of the pilot section and of an outer diameter somewhat less than the inner diameter of the bore hole guides the drill string through the bore hole.  The collar, mid-section, pilot section and bull nose are integral portions of the tool body.

Abstract: ABSTRACT       Integral, elongated panels have sets of con-verging corrugations arranged on lines defined by folded, transversely triangular elements.  These elements extend laterally across the panel, and are dimensioned such that a pair of adjacent parallel side edges of two correspond-ing panels can mate.  Preferably, each corrugation has a planar element arranged on lines generally perpendicular to the side edge defining congruent elements with tri-angular faces meeting at the apex.         By such arrangement, a panel is obtained which in conjunction with other such panels, can produce a curved surface, which curvature may be reversed in direction in any point along a structure surface, by inverting the next adjacent series of panels.

Abstract: A method and system for processing first and second seismic traces includes rotating the first seismic traces and the second seismic traces to forty-five degrees in the time domain. In one embodiment, the rotated first time domain traces and second time domain traces are transformed to the frequency domain to obtain an amplitude spectrum for each rotated first time domain trace and an amplitude spectrum for each rotated second time domain trace. Each amplitude spectrum is squared to obtain a power spectrum for each transformed and rotated time domain trace. The phase of each transformed rotated time domain trace to zero. The power spectrum for each transformed rotated time domain trace is then averaged. Each transformed rotated time domain trace is divided into time windows. A power spectrum for each window is obtained for the entire of each transformed rotated time domain trace. The power spectra of each window of the transformed rotated time domain trace is summed to obtain a summed first power spectrum. A third power spectrum representing a source wavelet is defined. The third power spectrum is divided by the power spectrum to obtain a set of frequency domain scalars. The amplitude power spectrum is multiplied by the set of frequency domain scalars. The result of this multiplication is inverse transformed. The amplitudes of the inverse transformed result is compared to derive an first amplitude scalar.

Abstract: The present invention concerns a catalyst suited to the aromatization reaction of light hydrocarbons. Such a heterogeneous catalyst contains zinc bound to a zeolite support material. The catalyst in accordance with the invention is prepared by adsorbing the zinc onto the surface of the zeolite support material directly from the vapour phase by way of chemisorption. The zeolite compound acting thus as the support material is here heated to a temperature which is above the condensation temperature of the zinc vapour. Advantageously, the preparation has been carried out at temperatures above 390  DEG C. The zinc vapour has been brought to contact the zeolite support material, whereby the vapour pressure of zinc is maintained sufficiently high and the duration of its interaction with the support material sufficiently long so as to provide at least an equal amount of or, preferably, an excess of zinc in relation to the available binding sites of the support material. In order to avoid the desorption of absorbed zinc, temperature in the preparation reaction of the catalyst in accordance with the invention has been maintained below 550  DEG C.

Abstract: Movement of the cover (B) relative to the housing (A) spring loads and latches a piston carrier (38) in the armed position. Inhalation causes a passageway door (14) to open, releasing the carrier latch (52) to permit the carrier to be moved toward the canister 18 by the spring 42. The piston 34 moves with the carrier 38, due to a fluid connection therebetween, applying a compression force on the spring loaded canister valve stem 32 and causing it to dispense the inhalant through an opening in the piston which functions as a nozzle. After the inhalant is dispensed, the carrier fluid vents permitting the spring of the canister valve stem to move the piston relative to the carrier, and thus release the force applied to the valve stem by the piston. The sensitivity of the toggle linkage between the door and the carrier latch is adjustable. The linkage can be manually tripped for testing purposes. <IMAGE>
