Abstract: A dual-purpose energy transfer/signal transmission line including a hollow tubular cord containing on the inner surface thereof a thin layer explosive, the ignition of which creates a shock wave of energy perpetuated through the cord, in which the cord contains a fiber-optic or electrical signal transmission line of substantially smaller diameter than the ID of the explosive cord. The invention also includes junction blocks allowing ingress/egress of the signal line into and out of the explosive cord.

Abstract: A flexure mechanism, the basic elements of which comprise a foundation plate, and a mounting plate which is desirably mounted generally parallel to the foundation plate and which is secured from the foundation plate by a series of flexible support elements, the support elements being secured to the foundation plate in a generally circular configuration and which incline conically, inwardly, into attachment to the mounting plate, also in a generally circular configuration. If the point of convergence of the support elements lies in the plane of the distal surface of the mounting plate, the foundation plate will move, in two degrees of freedom relative to the foundation plate much as if the two plates are pivotally connected to each other. The support elements may be adjustably mounted to the foundation plates and mounting plates, and means may be provided to move the mounting plate relative to the foundation plate.

Abstract: A drill/reamer bit is described that is particularly suitable for high speed operation and which comprises a bit having a "split" pilot or drill portion with four facets and two cutting edges on each web and a "step" or reamer portion having two reliefs and one cutting edge associated with each web, the webs being formed by a pair of flutes angled at from approximately 81/2.degree. to approximately 23.degree., the bit being formed primarily of fine grain tungsten carbide material, the drill portion having an included angle of approximately 118.+-.2 degrees.

Abstract: An improved finned heat exchanger tube wherein the upper circumferential portions of the fins are foreshortened to enhance axial movement of liquid introduced onto the top of the finned tube. Accordingly, the liquid can gravitate both axially and circumferentially of the finned tube and thoroughly wet the entire external surface thereof.

Abstract: A mounting mechanism for an endless traction band system in which the endless band is supported on and driven by a pair of laterally spaced roller chains. The mounting mechanism supports a double sprocket for engaging the chains and is adapted to permit a limited degree of skewing by the sprocket wheel shaft so as to maintain the sprockets in alignment with the roller chains even when the roller chains are deformed in response to laterally imposed loads.

Abstract: This invention involves a filament wound composite core which is combined with one or more additional cores to produce a loop track characterized by transverse curvature and stud bands extending between the sandwiched or laminated cores and which extend to provide sprocket engagement for transferring motive power to the loop track, and a system for mounting the novel loop track on a vehicle.

Abstract: A vehicle supporting endless traction band including an endless resilient band of concavo-convex transverse shape and a pair of assemblies for supporting and protecting opposite sides of the band. The assemblies are similar to conventional roller chains except that the inner support links (those adjacent the sides of the band) are configured to pivot on the chain studs and to define slots into which the side margins of the band are received. A plurality of tension resistant members obliquely span the space between the roller chain assemblies on the concave side of the band to prevent the band from buckling when subjected to concentrated loads.

Abstract: A device for separating essentially immiscible fluids such as oil from rough water which utilizes a drum-shaped mechanism having generally vertically disposed oleophilic discs rotatable about a horizontal oil receiving trough, the unit being mounted in a frame also providing a sump which allows rotation of the drum, the complete unit being able to follow wave motion substantially independently of a supporting vessel through use of slide and guide mechanisms providing fore and aft restraint while allowing freedom of movement in heave and roll independent of ship motions. A major portion of the interior area of the drum about which the oleophilic discs rotate is filled with buoyancy material.

Abstract: A device for separating, in an ice environment, fluids having differing physical properties which combine an oleophilic pick-up device with a rotating tumbler mechanism which tends to agitate and propel oil coated pieces of ice rearward and along a perforated inclined through-put barrier where oil jarred off the ice chunks is allowed to rise through the perforations and be contained in an area where it can be accumulated and recovered by the pick-up unit.

Abstract: An impact resistant external casing is provided to enclose a canister containing a multi-layered chemical bed, with by-passes in each layer to accommodate the flow across and through the bed of exhaled breath which reacts with potassium superoxide in tablet form, the casing being provided with a (top) lid section which contains a mouthpiece, breathing hoses, and neck straps, the opposite side of the casing being provided with a bottom cover which accommodates the storage of a folded breathing bag and chest straps. An air passageway constituting an annular section is provided to accommodate a chimney extending from the bag through the passageway section between the casing and the canister, which is open to ambient air for cooling purposes. The inside bottom portion of the canister is provided with a trammel to prevent escape of deliquesced KO.sub.
