Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides a batten structure which can be placed inside a double sided sail to provide a so-called "wing" sail having an airfoil section which can be close to an ideal airfoil on either tack.  The structure includes a central beam which engages the mast, a nose piece pivotably connected to the front end of the beam, and two flexible batten members each extending rearwardly from rigid connections on opposite sides of the nose piece and being slidably connected together at their rear ends. Spreaders which are movable relative to the beam connect the batten members and maintain its airfoil shape while allowing the batten members to flex when the wind moves from one side of the sail to the other.

Abstract: A METHOD OF FORMING AN AXLE                 Abstract of the Disclosure A method of forming an axle with hollow spindles which are each capable of supporting a rotatable hub having a wheel and tire mounted thereon.  Each hub would include an intermediate cavity which is sealed to define with a wall of the spindle a reservoir for inflation air for the tire.  Inflation air is supplied to the spindle at a region axially inwardly of the hub at a predetermined circumferential location thereon.  The steps of forming include providing each of the spindles with an outer cylindrical surface at the region.  Air passages are formed in the wall of the spindles communicating the intermediate cavity of the hub with a radially extending passage at the outer cylindrical surface.  Each of the spindles is welded respectively to the opposite ends of the central portion of the axle.  A pair of collar elements are formed with each collar element having an inner cylindrical surface matching the outer cylindrical surface of the spindle and a coupling passage and fitting for mating with the supply of inflation air.  Each of the collar elements is respectively installed on the outer cylindrical surface of each of the spindles with the radially extending passage and the coupling passage being connected by a circumferential groove which has been formed in either the outer or inner cylindrical surface and the fitting being positioned at the predetermined circumferential location for mating with the supply of inflation air.

Abstract: HOLE FILLING SYSTEM FOR TIRES                  ABSTRACT OF THE DISCLOSURE          A tool tip is inserted from the inside of the tire into a hole in a tire crown by turning the tool tip as  it  is  pressed against  the  tire.   The tool  tip  is mounted  on a  hollow  tool  having  a  cylindrical  insert receiving chamber.  An insert is pushed by a plunger out of  the  receiving  chamber  in  the hollow tool through a tapered portion  into a compression chamber  in the tool tip.  The compression chamber has a diameter smaller than the diameter of the insert so that when the insert is ejected from the hollow tool it will expand to fill the hole in the tire.   The insert is also tapered to engage the tapered portion between the receiving and compression chambers.  The plunger has a plunger head with a substan-tially flat pushing surface and knurled edges which the operator can manually grip and push.  The outside of the hollow tool is also shaped for manual gripping to turn the hollow tool  and tool  tip in  the same direction during insertion and removal of the tool tip from the tire to leave an undamaged insert in the hole.

Abstract: TRACTOR-TRAILER BRAKE ACCELERATION SYSTEM                   ABSTRACT OF THE DISCLOSURE A brake activation system for reducing the time between the brake application of tractors and trailers utilizes a speed differential between the electrical and air signals.  The application of the tractor brake actuates simultaneously a stop light circuit and the air brake systems.  The electrical signals from this energized stop light circuit actuates solenoid valve which releases the air from the trailer reservoir being subsequently reduced to a predetermined low pressure level.  This low pressure air reaches the trailer wheel brake chambers prior to the arrival of the brake air with high pressure overriding the low pressure air route and completing the trailer brake application.

Abstract: ABSTRACT     The invention relates to an arrangement for improving heat economy in a rotary kiln, in particular in a kiln for reburning of lime mud.  The drying and intermediate zones of the kiln chamber are furnished in part with turbulence-forming arrangements to produce a turbulent motion in the hot combustion gases and thereby to force the hotter gases, which flow through the axial central region of the kiln, out towards the kiln wall.  The kiln shell is additionally furnished with thresholds in order to increase the transit time of the material through the kiln and further with lifters and a cog-wheel lining in order to lift the material and bring it into contact with the gases.     In order to recover the heat from the burnt lime and thereby further improve the heat economy the burner tube is furnished with turbulence-forming baffles and the surrounding kiln shell with lifters and with thresholds at both ends of the burner tube in order to bring the hot burnt lime in contact with the combustion gases and the kiln lining.
