Abstract: Apparatus and method for improving the fuel economy and noxious emission levels of a gaseous fueled engine by the use of a combustion chamber in a flat topped piston which is smaller in area and deeper than the combustion chamber in a conventional piston. The chamber is offset from the central axis of the piston to cause the squish velocity of the combustion mixture to be high in the vicinity of an ignition device. Also, the chamber is non-circular in shape to create higher turbulence throughout the combustion region.

Abstract: An eye shield formed of inner and outer layers of soft fabric with a flexible sun blocking material located between the inner and outer sheets of fabric for blocking total sun rays including harmful ultraviolet rays and having a relatively thick layer of soft material located between the inner and outer sheets of fabric to provide body to the mask-like portion and comfort to the wearer. The eye shield also includes a relatively small sight opening formed in each eye member and a semi-opaque lens plate extending across the eye member sight openings for blocking harmful ultraviolet rays. The sight opening may be located below the center of each eye member in order to prevent light rays from impinging directly on the eye of the wearer. In addition, portions of the straps forming the eye shield may be formed of material substantially transparent to ultraviolet tanning light rays such that the skin of the user may tan in those areas thereby avoiding white strap marks.

Abstract: An electrosurgical knife includes a stainless steel blade whose surface is abraided or etched, a first coat of primer material applied over the blade, where the surface of the primer material is also abraided or etched, and a second coat of non-stick fluorinated hydrocarbon material applied over the coat of primer material to cover the primer material, for a total thickness of about three mils. The stainless steel blade is completely covered by the coatings but the thickness of the coatings is not so great as to prevent conduction of radio-frequency electrical energy from the blade through the coatings to tissue being cut.

Abstract: A pressure variable sealed container such as a length of rubber tubing is filled with a compressible, thermally conductive fluid such as helium or hydrogen and is placed in a sealed motor stator chamber otherwise filled with a heat conductive liquid, such as oil, before final assembly. As the oil in the stator chamber expands with temperature, the thermally conductive fluid in the container is compressed thereby absorbing the expansion of the oil in the stator chamber.

Abstract: Bleaching laundry in a bath using a peroxidized compound characterized in that bleaching is carred out at a pH of between 10.5 and 12.5 in the presence of calcium peroxide (CaO.sub.2) as the peroxidized compound, introduced in the hydrated or the anhydrous form so that the quantity of calcium per liter of bath is between 1.times.10.sup.-3 and 1.times.10.sup.-2 gram-atom.

Abstract: A central body portion has first, second and third concentric cylinders of successively increasing diameter encircling the central body portion and each other in spaced relationship to form three concentric annular spaces for receiving molten material. Only one end of each of the first, second and third cylinders and the body portion are rigidly attached to each other so as to maintain the rigid spaced relationship. A mandrel is attached to the outer end of the central body portion and a die is attached to the outer end of the outer most concentric cylinder in spaced relationship to the mandrel to shape the molten material into a pipe having a multi-layered wall.
