Abstract: ABSTRACT OF THE DISCLOSURE       The outboard motor includes a powerhead housing defining an engine compartment for an internal combustion engine and a vent assembly for ventilating the engine compartment to the atmosphere.  The vent assembly includes a tubular member mounted in an aperture in the housing bottom wall and having an inlet port communicating with the interior of the engine compartment, an outlet communicating with the atmosphere and an interior wall defining a bulbous passage between the inlet and outlet ports.  Under normal operating conditions, a buoyant ball valve movably disposed in the bulbous passage is held in an open position by gravity to afford free air flow into and out of the engine compartment.  In the event the water rises to a level above the housing bottom wall, the ball valve floats on the water entering through the vent assembly outlet and sealingly engages a valve seating surface to prevent entry of water into the engine compartment.

Abstract: ABSTRACT         An apparatus and method is disclosed for attaching a continuously moving elastic ribbon to a continuously moving web such that only selected discrete areas of a finished conformable garment fabricated from the web are elasticized.          The web is moved into engagement with a continuously moving first conveyor means having a plurality of spaced apart gaps in its surface and the first conveyor means travels along an inclined guide means toward a second conveyor means traveling opposite to and in the same direction as the first conveyor means.  The second conveyor means carries a plurality of spaced apart web tucking means which are moved by the second conveyor means into registry with the gaps in the first conveyor means.  As each of the web tuck means move in registry with the gaps, the web tuck means are inserted into the gaps to form tucks in the web due to the movement of the first conveyor means toward the second conveyor means.  After forming of the tucks in the web, the continuously moving elastic ribbon is applied to the web such that it spans the tucks and adheres to the area of the web between the tucks.          The elastic ribbon is then cut opposite the tuck locations of the web and the tucks are removed from the web.

Abstract: BLOOD VESSEL CATHETER FOR MEDICINE DELIVERY AND METHOD OF MANUFACTURE Abstract A catheter which is capable of delivering medicine into a blood vessel at a selected point, such as into a coronary artery, includes an outer tube which is joined to the outside diameter of an inner tube by drawing the tubes through a heated die. A distal portion of the outer tube extends beyond the distal end of the inner tube, and the outer tube is formed from a polymeric material having a substantially lower flexural modulus than the polymeric material of the inner tube so that the distal portion is relatively flexible for enabling insertion in a tortuous blood vessel. The inner diameters of the inner tube and the distal portion of the outer tube permit insertion of a guide wire therethrough for aiding in the insertion of the catheter.

Abstract: Mo-2462 LeA 21,568 A SINGLE-STAGE PROCESS FOR THE PRODUCTION OF POLYAMINES AND POLYAMINES PRODUCED BY SUCH PROCESS                  ABSTRACT OF THE DISCLOSURE         Polyamines containing from 0.19 to 20.3 wt % primary amino groups are produced by hydrolyzing in a single stage an isocyanate with an excess of water, a relatively weak basic compound and a water-miscible polar solvent at a temperature from 50 to 165°C.  The hydrolysis is conducted in a manner such that the reactants are substantially homogeneous during the reaction.  The isocyanate should have an NCO-content of from 0.5 to 40 wt %.  The weakly basic compound may be a carbonate or hydrogen carbonate of an alkali metal or an alkali or alkaline earth salt of a monocarboxylic or polycarboxylic acid or mixtures of such materials. The polyamines produced by this process are particularly useful in the production of polyurethanes.

Abstract: ABSTRACT    Apparatus for terminating a flat flexible cable comprises an anvil supporting an electrical connector, and a punch for driving the conductors of a flat flexible cable into conductor-relieving slots in individual terminals of the connector.  Upon the cable end engaging a stop, a cable notching jaw is closed against a fixed cable notching jaw, to form notches between the conductors of the cable and the jaws are then retracted to allow the punch and the anvil to be moved towards one another to terminate the cable end to the terminals of the connector.          The jaws are then returned so that the forward end thereof ejects the terminated connector from between the punch and anvil which have now been moved away from one another to allow this.

Abstract: ABSTRACT     A suspension system for an operator's compartment of a mine vehicle is set forth.  The mine vehicle is of a type that has a body and a operator's compartment positioned adjacent to the body.  A guide is attached to the body of the vehicle and a rail is attached to the operator's compartment.  This guide and rail arrangement slidably connects the operator's compartment to the body.  The guide and rail are arranged to permit the operator's compartment to indecently move upward and down in relation to the body.      The rail is located in a central portion of the operator's compartment to minimize the angular displacement of the rail with respect to the guide upon rotation of the operator's compartment.  This ensures free upward and downward motion of the operator's compartment with respect to the body of the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE         Novel apparatus is provided herein for handling and counting sheets.  The apparatus includes feed roller means each rotatable about a first axis and stripper means each forming a first nip with the feed roller means for advancing single sheets past the first nips.  Rotatable driven roller means are provided which are coaxial with the first axis.          Acceleration drive roller means are provided which are rotatable about a second axis displaced from the first axis.  Closed loop belt means are provided for coupling drive from the acceleration drive roller means to the driven roller means.  Idler means are provided in which the periphery thereof rollingly engages the acceleration drive roller means and forms a second nip for accelerating sheets entering the second nip.  Finally, guide means cooperate with the belt means for guiding sheets between the first and second nips.  By this apparatus the acceleration means provided to facilitate sheet counting utilizes elongated closed loop belt means to permit the handling and counting of sheets whose lengths extend over a relatively broad range to provide some pre-acceleration and to avoid the need for increase in the size of the feed rollers, to avoid damage to sheets and to provide quieter operation.

Abstract: ABSTRACT OF THE DISCLOSURE     The  present  invention  features an arrangement wherein in order to prevent atmospheric air (or the like) from entering the cooling system of an engine wherein the coolant is boiled and the vapour used as a vehicle for removing heat from the engine, upon the engine being stopped or the temperature of the system falling  below  a predetermined  level,  the  cooling system  is  filled  with  liquid  coolant  under  the influence of the sub-atmospheric pressure which tends to develop under such conditions.  Additionally, the coolant can be pumped in, in the event that some air has entered or remains in either of the coolant jacket or radiator associated therewith,  to displace said non-condensible matter out of the system and thus completely  obviate  any  tendancy  for  which  would otherwise tend to produce a heat exchange reducing "embolism" to occur in the radiator conduiting.
