Abstract: Abstract of the Disclosure A method and apparatus are provided for removing closures form containers that are assembled in cases which are moved seriatum into position below multiple spindles arranged with respect to the container positions in the case.  Each spindle has a non-rotatable internally threaded nut with a freely rotatable externally threaded screw therethrough, and a head unit for gripping a closure on the container.  Axail displacement of the multiple spindles with respect to the containers causes the head unit of each spindle to grip a container only by its clo-sure, if it has one thereon.  Axial displacement of the screw with respect to the nut rotates the screw with sufficiant torque to break any bond or seal securing the closure without need of holding the container to prevent its rotation.

Abstract: IMPROVED DISPOSABLE DIAPER HAVING     REFASTENABLE TAPE SYSTEM                             Abstract An improved disposable diaper of the type having a relatively high elongation to tensile force property, an absorbent pad, and tape-tab fasteners coated with a peelable adhesive.  The backsheet is reinforced by coating the mother's bond region thereof with a material having high tensile strength and a low elongation to tensile force property relative to the backsheet material.  The coating may be continuous or patterned and may be disposed on either the outwardly facing surface or the inwardly facing surface of the mother's bond region of the backsheet.  When applied to the inwardly facing surface, the coating material may be adhesive material and may secure the backsheet to the pad assembly of the diaper.  The reinforcement of the backsheet improves the resistance of the backsheet to stretching and tearing when subjected to tensile forces during fastening and wearing, and to peeling forces when the tape-tab fasteners are being peeled open.  Thus, the fasteners are refastenable.

Abstract: MECHANICAL POWER TRANSMITTING SYSTEM     ABSTRACT OF THE DISCLOSURE          In a mechanical system including a rotatable drive member and a load, a power transmitting device utilizing centri-fugal force is employed for connecting the drive member to the load.  In the device sequentially occurring centrifugal forces of opposite direction are generated by one or more weight means driven by the drive member and constrained to move about an associated endless path fixed to a carriage or carrier that reciprocates under the influence of the centrifugal forces.  The reciprocating carriage is in turn drivingly connected to a load. which may either be a power absorbing device or a tool for work-ing on some other material.  The power transmitting device has the inherent ability to function as an automatic transmission or torque converter to cause an input force or torque to be applied to the load at relatively low speeds when the load is heavy and at relatively higher speeds when the load is light.  The power transmitting device is shown in various and different embodiments with carriages that reciprocate either along straight line paths or along circular paths.

Abstract: GRASS DISCHARGE CHUTE DEFLECTOR       FOR ROTARY LAWN MOWER                           ABSTRACT         A lawn mower comprises a housing enclosing a rotary cutting blade.  The housing includes a continuous sidewall having therein a side grass discharge opening and a top wall extending from the sidewall and having therein a top grass discharge opening.  A deflector is located on the housing adjacent to the side discharge opening and is operative for movement between an open position permitting the escape of grass clippings through the side discharge opening and a closed position blocking the escape of grass clippings through the side discharge opening.  The deflector is biased toward the open position.  A grass discharge chute is detachably attached on the housing in communica-tion with the top discharge opening.  The chute includes a tab member which engages the deflector and moves the deflector from its open position to its closed position against the action of the bias during attachment of the grass discharge chute on the housing.  The tab member also maintains the deflector in its closed position against the action of the bias when the grass discharge chute is attached on the housing.

Abstract: TERNARY LOGIC CIRCUITS WITH CMOS INTEGRATED CIRCUITS            Abstract of the Disclosure:           Ternary storage elements are realized using ternary operators and fundamental circuits, designed to make practical use of CMOS (or COS/MOS) integrated circuits.  Word-organized and trit-organized memory cells are designed for the construction of a ternary random-access-memory array (TRAM). Several flip-flops (tri-flops) are constructed and described in detail, including a PZN (set positive, set zero and set negative), a clocked PZN, a D-type and a T-type.  Ternary shift registers and ring counters are formed by means of these tri-flops.  A master-slave T-type tri-flop is used for the construction of a ternary up counter which is able to count from 0 to 3n using the normal ternary code or from -(3n-1)/2 to +(3n-1)/2 when the signed-ternary code is employed.  With a little modification, a ternary down counter may also be constructed.  A divide-by-M ternary counter which can be programmed is described. A ternary decoder and encoder are presented, which are the elements of a complete ternary read-only-memory (TROM).  A modified ternary inverter (MTI) is taken as a unit cell of a ternary memory matrix.

Abstract: Le projectile cylindrique (13) est engagé dans le tube propulseur (1) de façon que son fond se trouve en contact avec le fond (5) qui ferme la culasse (4) prolongeant le tube (1). L'enceinte (8) communique avec le tube (1) grâce au conduit coudé (7) et à l'ouverture latérale qui est ménagée dans la culasse (4) et raccordée au conduit (7). Quand le projectile est en place, les garnitures (14, 15) obturent toute communication entre le tube (1) et l'enceinte (8). Cette dernière peut être remplie d'air comprimé par exemple au moyen d'un raccord vissé dans un des trous taraudés (12). Il suffit dès lors de déplacer le projectile (13) vers l'avant par enfoncement de la tige (16). Sous l'effet de la poussée de l'air le projectile se déplace et les dimensions du passage libre augmentent rapidement, ce qui assure un effet propulsif maximum. (Fig. 1)

Abstract: METHOD AND APPARATUS FOR MASK/WAFER ALIGNMENT            Abstract Zone plate patterns formed on spaced-apart mask and wafer members are utilized for alignment purposes in the fabrication of integrated circuits.  By providing off-axis illumination of the patterns, a significant mask-to-wafer alignment capability is provided in an X-ray lithographic system.  This capability includes being able to correct for so-called magnification errors that arise from physical distortions in the mask and/or wafer or in other components of the system.  These errors are compensated for by utilizing the zone plate patterns to form alignment marks that serve as a basis for adjusting the mask-to-wafer separation.

Abstract: ABSTRACT           The sputtering cathode (10) forming part of the apparatus of the invention essentially comprises a target (20) made of a material to be sputtered, arranged in front of an intermediate support (15) so as to define a first tight chamber (30) of low thickness therebetween, intended to be provided with an atmosphere of a gas (37) presenting a high thermal conductivity (under a pressure substantially higher than that prevailing inside the vacuum chamber of the apparatus). The intermediate support (15) in turn forms part of the wall of a second tight chamber adjoining said first tight chamber, which is intended to be circulated with a liquid coolant therewithin. The above arrangement enables the sputtering target (20) to be consumed up to its piercing without causing any damage for the apparatus and/or the substrates being coated, since this piercing will result in a simple gas irruption inside the vacuum chamber (3), which may be at once detected for immediately controlling the automatic cut-off of the sputtering operation.  The above arrangement further enables a sufficient target cooling throughout the sputtering.
