Abstract: RIBBON FEED APPARATUS      Abstract of the Disclosure An apparatus is provided for employment of a double-width ribbon in a printing apparatus, in which a complete traverse of a ribbon extending between a ribbon supply spool and a ribbon take-up spool at different levels may be completed, utilizing one-half of the width of the ribbon in cooperative relation with a printing device, after which the ribbon and associated spools are removed from the printing apparatus, reversed and replaced, so that the unused portion of the width of the ribbon is placed in operative relationship with the printing device, and a second traverse of the ribbon in a printing operation may then be completed.  The apparatus includes drive mechanism for driving one of the spools, brake mechanism for selectively braking the movement of at least one of the spools, ribbon diverter mechanism for controlling the path of the ribbon between the spools and for changing the path and inverting the top and bottom of the ribbon from one level to another, a guide for supporting the diverter mechanism for movement along a predetermined path, and resilient mechanism coacting with the guide and diverter mechanism to maintain proper tension in the ribbon as it is fed from one spool past the printing device to the other spool.

Abstract: PORTABLE MULTI-HULL WATERCRAFT KIT                 Abstract of the Disclosure A readily portable kit for assembling a multiple hulled watercraft, such as a catamaran, from two or more open-hulled boats such as canoes is disclosed.  The kit in one embodiment allows the assembly, using two stand-ard canoes, of a stable catamaran having a large deck surface.  The multiple hulled vessel may be rapidly assembled or disassembled using novel fastening means which allows the deck to be tied down with straps or other suitable hardware.  In its disassembled state, the kit and hulls may be readily and compactly carried on the roof of a car or van.  In its assembled condition, the deck acts to seal the open hulls, creating a stable, substantially water-tight watercraft of large capacity.          The deck is constructed to enable the erection thereon of a tent, or similar collapsible shelter, including a water-tight protective shroud around the circumference of the tent, and in one variation, a protective tar-paulin above the tent.

Abstract: SURFACE CONDENSER/WATER HEATING                       ABSTRACT     An assembly and method provide for the simultaneous heating of process inlet water from a clean water source, and condensing of a condensable gas using the process inlet water and a closed loop of condensing water.  A plurality of pairs of condenser plates are disposed in an annular array in a vertical cylindrical vessel.  First and second liquid inlets are disposed at the top of the vessel separated by a radially extending fixed baffle, and first and second liquid outlets are disposed at the bottom of the vessel separated by a radially extending fixed baffle.  A condensable gas passes through the interiors of the pairs of condensing plates.  Movable top and bottom baffles are rotatable through arcs to change the number of condensing plates operatively communicating the first liquid inlet with respect to the second liquid inlet, the liquid flowing between the first liquid inlet and outlet being always segregated from the liquid flowing between the second liquid inlet and outlet.  The first inlet is connected up to a source of clean water, such as a river, and the movement of the baffles is adjusted in response to the tempera-ture of the water in the river.  The second liquid inlet and outlet may be operatively connected to a cooling tower, while the first liquid outlet may be connected to a paper pulp washing station.

Abstract: ABSTRACT OF THE DISCLOSURE          The instrument disclosed herein is designed for measuring flow rates and densities of moving fluid streams, including liquids, gases, slurries, and fluids which contain solid materials. Basic components of this instrument are a dynamic leg and a static leg, and flexible connections in each leg which allow for displacement caused by the force of the moving fluid. Each leg is defined by a conduit member having several bends therein, which are joined by straight sections. The legs are held in physical contact along one of the straight sections, and a displacement transducer unit is installed at this point.  In operation, part of the incoming fluid to be measured for flow rate fills the static leg and remains in this leg.  After the static leg is full, all of the incoming fluid moves through the dynamic leg, and fluid pressure is in equilibrium within the system.  This removes the effect of fluid pressure on the flow rate and density measurement, so that the displacement transducer senses and records only the force generated by the moving fluids.  Flow rate is then calculated as a function of this force.  A separate transducer measures the velocity of the stream, and this measurement is converted to a density value.

Abstract: CLAW HAMMER FOR DRIVING AND EXTRACTING NAILS            ABSTRACT OF THE DISCLOSURE                      A claw hammer head has a fulcrum member hinged by a hinge assembly to the head for swinging between retracted and extended positions. In the retracted position, the fulcrum member is retained in a recess in the head so that the hammer can be used for driving nails into a work surface in the normal manner. In the extended position, the fulcrum member is swung relative to the head to extend beyond the head so as to increase leverage for extracting nails from the surface. The fulcrum member is hinged to the head in such a manner that load incurred while extracting nails is transferred essentially directly to a bearing surface of the hammer head, and thus relieves load from the hinge assembly. The fulcrum member has a periphery that contacts the work surface in the extended position, the periphery having a relatively large radius of curvature for initially extracting the nail, and then rolls onto a smaller radius of curvature when the nail is partially removed from the surface, thus relieving the work surface of high initial loading, and reducing damage to the surface.

Abstract: ABSTRACT A pulse counting device wherein a number of pulses is stored in a first register (91) out of a plurality of registers (91 - 9N), and subsequently a new pulse number counted is stored in the first register (91) and pulse numbers stored in the registers (91 - 9N) are successively shifted with a pulse number erased from a final register (9N).  The pulse numbers stored in the respective registers (91 - 9N) are corrected dependent on the latest pulse number stored in the first register (91), and a value dependent on the corrected values stored in all of the registers (91 - 9N) is displayed.  If the latest pulse number is abruptly varied in excess of a certain preset value upon comparison with the pulse numbers in the registers, then the pulse numbers in the registers are corrected with a value dependent on the latest pulse number.  If the latest pulse number is varied gradually within the preset value upon comparison with the pulse numbers in the registers, then the pulse numbers in all of the registers (91 - 9N) are compared to correct the pulse numbers in prescribed registers into a certain sequence of numbers.  With this arrangement, a display unit (14) of the pulse counting device has a quick response with respect to variations in the latest pulse number.

Abstract: ABSTRACT          A magnetic audio or video tape is smoothed and/or otherwise treated by causing it to pass through one or more calenders wherein a large-diameter primary calender roll is heated from within and the major part of its peripheral surface is surrounded by the running tape.  The primary roll rotates about a fixed axis and is surrounded by a cluster of two or more smaller-diameter secondary calender rolls each of which has a viscoelastic peripheral layer and each of which can be individually biased against the adjacent portion of the running tape with a selected force.  The magnetic film on the tape is out of contact with the secondary rolls as well as with the guide rollers which cause the tape to advance toward the peripheral surface of the primary roll and thereupon toward a takeup reel.
