Abstract: The invention relates to a pump-inflow-cannula (1) providing a blood conduit from a heart (2) and/or from an associated vessel to an external blood handling system, said pump-inflow-cannula (1) comprising a body (3), encompassing an inflow-lumen (4), extending essentially axially along a center-line (5), having a distal-end (6) for an attachment of the inflow-lumen (4) to said blood handling system, and having a proximal-end (7) for an introduction of blood from the heart (2) and/or from the associated vessel into the inflow-lumen (4). At the proximal-end (7) at least one angled-hole (8), extending around a longitudinal hole-axis (9) is provided, and said hole-axis (9) includes a presettable hole-angle (?) with the center-line (5) of the inflow-lumen (4), wherein said body (3) of the pump-inflow-cannula (1) comprises a reinforcement-means (10).

Abstract: A method of making an elastomer lined composite vessel or portion of such vessel is disclosed. The method comprises causing a thin, tacky ribbon comprising an elastomer (preferably curable) to continuously so encircle a center rotational axis of a madrel as to adjacently position and tack together integral segments of the ribbon substantially circumferentially relative to this center rotational axis thereby forming a layer of the elastomer about the mandrel which may be the shell of the pressure vessel in case of internal application of the insulator or may be a workpiece around which the shell is built over the so-layed ribbon.

Abstract: Side looking sonar apparatus on a carrier vehicle obtains an acoustic picture of a target area below the vehicle from some minimum range out to some maximum range on either side of the vehicle. An angle look sonar obtains an acoustic picture within the gap portion between the minimum range points of the side looking sonar. Signals are obtained indicative of the heading of the vehicle as well as its actual direction of motion. These signals are utilized to generate a crab angle signal which is utilized to rotate the angle look sonar apparatus to the proper orientation for obtaining complete bottom coverage even when the carrier vehicle is crabbing due to a cross current.

Abstract: The invention is a pocket-sized card holder for keys, coins and/or similar items comprised of a thin card having a depressed region therein for receiving and containing the items and a pressure resealable, at least partially adhesively-coated lid which covers the depressed region and which can be stripped or peeled back to expose the contained items. The holder is preferably of credit card size for convenience in carrying, with overall thickness only fractionally greater than the items contained.

Abstract: A process is disclosed for installing an elastomeric liner in a pressure vessel. The process comprises winding a tacky ribbon around an expandable mandrel, inserting it in the vessel shell, expanding the mandrel and optionally curing the wound ribbon.
