Abstract: Abstract of the Disclosure An ocean mining system for mining manganese nodules comprises a sur-face subsystem and an ocean bottom subsystem.  The ocean bottom subsystem includes a mobile maneuverable, self-propelled, miner vehicle which picks up, handles, washes and crushes nodules while retaining nodule fines.  The under-water subsystem also includes a buffer which functions to provide temporary storage for nodule material picked up and crushed by the miner vehicle.  The buffer further serves to isolate the miner vehicle from the  dynamics of a pipe string extending down from a surface ship.  All equipment not needed for operation of the miner vehicle is located on the buffer to distribute the weight between the buffer and the miner vehicle in a way that provides maximum mobility of the miner vehicle.  The underwater subsystem also includes a flexible link-age, extending between the  miner vehicle and the buffer.  A flotation block holds the flexible linkage up and out of the way of the miner vehicle during operation of the vehicle.  This flexible linkage permits operation of the miner vehicle within a boundary envelope beneath the buffer as determined by the flexible linkage.  The surface subsystem includes a ship which provides all operational control and maintenance support for the bottom subsystem.  The ocean mining system includes sensors and controls.  The sensors sense the location of the miner vehicle within the permitted area of operation, display the topography of the ocean floor adjacent the miner vehicle and also display all aspects of the movement of the miner vehicle and pick-up and handling of the nodules.  The controls provide active control of every com-ponent of the  ocean bottom subsystem from the surface ship.

Abstract: 1176.005 S P E C I F I C A T I O N            ROTARY FOOD PROCESSING TOOL HAVING           OFFSET HUB              INVENTOR: JAMES E. WILLIAMS                ABSTRACT OF THE DISCLOSURE            A rotary food processing tool is provided for use in a food processor of the type including a housing containing an electric motor drive, a bowl mountable on the housing for enclosing the tool, said tool being rotated by said motor drive, and a removable cover on the bowl with a feed tube for feeding food items onto the rotating tool and into the bowl.  The rotary tool has an elongated hub with a head on one end and coupling means adapted to be coupled to the electric motor drive.  The head of the hub is offset from the coupling means such that it revolves around the axis of rotation of the coupling means.  The tool includes a horizontal disc-like member mounted on the huh head at a location radially offset from the center axis of the disc-like member.  Cutting means on the disc member extends from near the axis to the periphery.  Accordingly, the cutting means, which may be a slicing blade or other cutting imple-ments, extends for substantially the entire radius of the disc member contrasting with prior art tools wherein the hub is central and, therefore, prior cutting means can extend or only part of the radius, providing a significantly shorter cutting surface and smaller cutting capacity.  The novel cutting surface extending for substantially a full radius of the disc member permits processing of larger food items and accommodates use of feed tubes of larger radial width for feeding larger food items.

Abstract: ABSTRACT An apparatus for compressing a web W of fibrous material where the apparatus includes a first surface 3 movable in one direction and a second surface 5 movable in an opposite direction at a speed slower than the speed of movement of the first surface. A confining means 7 having an apex 10 extends between the surfaces. A stuffing chamber 13 is formed between the two surfaces and the confining means.  Movement of the first surface feeds a web of material into the stuffing chamber and movement of the second surface moves compressed material out of the chamber.          A method of compressing a web W of fibrous material where said material is forced into a stuffing chamber 13 formed between a confining means 7 having an apex 10 and two surfaces 3 and 5.  A web of material is fed into the stuffing chamber by moving one of the surfaces in one direction at a particular speed. Compressed material is removed from the stuffing chamber by moving the second surface in a direction opposite to that of the first surface and at a slower speed than that of movement of the first surface.

Abstract: CATALAC FREE ELECTRON LASER                 ABSTRACT OF THE DISCLOSURE    A catalac free electron laser using a rf linac (catalac) which acts as a catalyst to accelerate an electron beam in an initial pass through the catalac and decelerate the electron beam during a second pass through the catalac.  During the second pass through the catalac, energy is extracted from the electron beam and transformed to energy of the accelerating fields of the catalac to increase efficiency of the device.          Various embodiments disclose the use of post linacs to add electron beam energy extracted by the wiggler and the use of supplementary catalacs to extract energy at various energy peaks produced by the free electron laser wiggler to further enhance efficiency of the catalac free electron laser.  The catalac free electron laser can be used in conjunction with a simple resonator, a ring resonator or as an amplifier in conjunction with a master oscillator laser.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved connector assembly is provided for providing sealed and preferably sterile connection between a pair of conduits which each terminate in a hollow, trans-parent housing where some of the wall of each housing comprises a meltable wall portion sealed to the remainder of the housing.  The meltable wall portions of each housing are positioned in facing contact with each other and are held in sealed, retentive relationship so that exposure to radiant energy causes them to fuse and open an aperture therethrough.  In accordance with this invention, improved retention means are provided to permit the respective housings to be moved together in a path which is generally parallel to the opaque walls into sliding retaining relation.  Such retention means includes a track-defining gripper arm positioned near a first end of each housing and a flange positioned near a second end of each housing so that one of the flanges is adapted to fit in sliding retaining relationship within the track of the other housing.
