Abstract: An apparatus and method for comminuting and/or eliminating constricted areas in vessels of all types whereby fissures and cracks in the vessel walls during the treatment of stenosis in blood vessels and also coronary obstruction are to be avoided. A treatment catheter is used which is equipped with two inflatable balloons which seal off a constriction place in a vessel on both sides thereof whereby the degree of expansion of both balloons is externally regulatable. An inlet member for the supply of means dissolving the material of the constriction area or comminuting the same into smaller particles and an outlet member for the removal of the dissolved or comminuted material of the constriction place are provided in the walls of the treatment catheter within the area delimited by the two balloons. These inlet and outlet members are in communication with a channel accessible from the outside.

Abstract: An omelette mix is prepared from a liquid egg product, which may be, for example, whole egg, egg white, egg yolk, a de-chloresterized or artificial mix, or any combination of two or more of the foregoing, by adjusting its pH, preferably with citric acid, then adding to it a hydrocolloid, comprising an alginate, adding a multivalent metal salt of only low solubility in water, e.g. calcium sulphate dihydrate, in order to facilitate any required cross-linking of the hydrocolloid molecular chains, mixing thoroughly to form a homogeneous material, forming this material into any desired shape and freezing or chilling it to produce a stable intermediate material that can readily be quickly heated to give an omelette in form ready for consumption. In general sodium chloride will be introduced into the mix, conveniently with the hydrocolloid, in order to enhance the flavour of the omelette. A sequestrant is desirably added to control the release of the multivalent metal salt and thus regulate the speed of the cross-linking reaction.

Abstract: A container capable of being evacuated by a pump which is removably and sealably attached thereto comprises a cover having a removable valve mounted therein and a container body which is adapted to receive the cover.  A compressible indication member is positioned between the periphery of the cover and container body, the visibility of which from the outside of the container provides an indication of the evacuation state of the container.  The cover and the container body are movable relative to each other which movement is dependent on the pressure difference between the interior and the surroundings of the container whereby the deformation of the indication member provides an indication of the amount of pressure in the container.

Granted: 1992-04-28
Abstract: "PROCESS FOR REPLACING A LENGTH OF BURIED PIPE"           ABSTRACT OF THE DISCLOSURE The process comprises excavating pits at the first and second ends of a buried section of old water main pipe that is to be replaced with new pipe.  The exposed segments of pipe are broken up to provide access to the bore of the old pipe.  A pipe splitter and a cylinder-actuated pulling unit are installed in the first pit.  A string of rods is extended through the old pipe bore from the first pit to the second pit.   A tool assembly of sequentially connected components is attached to the second end of the rod string. The tool assembly may comprise:  means for centralizing the second end of the rod string in the second end of the old pipe section; a pull plate for bearing against the annular second end face of the old pipe section; a cylindrical plug for expanding the passageway extending between the pits; a rod member for extending through the bore of the new pipe section to be installed; and a second pull plate for bearing against the annular second end face of the new pipe.  The new pipe section is mounted on the rod member and the string of rods is tripped to the first pit.  In the course of tripping or retracting the rod string,  the following actions simultaneously occur:  the old pipe is advanced out of the passageway by pulling on it with the first pull plate; the old pipe is split longitudinally as it is advanced into the first pit; the diameter of the passageway is expanded by the plug; and the new pipe is pulled into the expanded passageway to replace the old pipe with the new pipe.

Abstract: CLOSURES                 Abstract of the Disclosure A closure, particularly, a telephone closure base with two closure members and a movable shear locking mem-ber.  In a closed condition of the closure, aligned aper-tures of the two closure members may receive the locking member to hold the assembly closed.  A part of one of the closure members having the aperture is flexible and tensile and has a flexure position such that, when an opening force is applied to the assembly with the locking member extend-ing through the apertures, the flexible part is flexed under tension and is urged against an opposing surface of the other closure member formed with the corresponding aperture.  This flexing action places the locking member mainly in shear while minimizing any bending forces upon the locking member.    - i -

Title: Tendons for prestressed concrete structures and method of using and process for making such tendons
Inventor: KURAUCHI MAKOTO

Filed: 1990-06-29
Granted: 1994-05-10
Abstract: \                   ABSTRACT OF THE DISCLOSURE            A tendon for prestressed concrete structure includes a core member such as a steel wire, a steel strand or a steel bar; and an unset bonding material coating the core structure to a predetermined thickness, having a specific setting time determined by selectively determining the respective contents of the bonding material and which sets at an ordinary temperature by chemical reaction; and a seamless corrugated sheath with a long span.  The tendon is manufactured continuously by coating a wire strand core member with an unset bonding adhesive, melt extruding and shrinking a seamless plastic sheath around the coated core member, deforming the plastic sheath to a corrugated shape with the depth of an indented portion being deeper than the thickness of the plastic forming the sheath and cooling the tendon.  The tendon with a long span is wound on the reel for storage, paid off from the reel and cut to the predetermined length, and anchorages are attached to the end of each reel.  The tendon is arranged in a desired arrangement for forming a prestressed concrete structure, concrete is placed so as to bury the tendons therein, and then the tendons are tensioned and fixed after the strength of the deposited concrete has increased to a degree to permit tensioning the tendons and before the unset bonding material sets.  Thus, the unset bonding material sets after the tendons have been tensioned and bonds the tendons firmly to the prestressed concrete structure.
