  • Patent number: 4202300
    Abstract: In an internal combustion engine intended to provide high fuel economy, low noxious emissions and high power, a pair of four cycle power cylinders are alternately fed by a two cycle charge cylinder in which a rich air/fuel mixture is compressed and delivered alternately to variable volume charge chambers communicating with the power cylinders, the three cylinders operating off a common crankshaft. A lean air/fuel mixture is inducted to each power cylinder on its intake stroke. Ignition occurs in the charge chamber and the flame front moves therefrom into the lean mixture in the power cylinder. The volume of the charge chamber may be varied in response to power requirements of the engine. A valve between the charge cylinder and charge chamber blocks flow therebetween during ignition and provides a restricted orifice between the charge chamber and power cylinder during the compression stroke controlling flow therebetween.

  • Patent number: 4197708
    Abstract: A thermal energy scavenger assembly including a plurality of temperature-sensitive wires made of material which exhibits shape memory due to a thermoelastic, martensitic phase transformation. The wires are placed in tension between fixed and movable plates which are, in turn, supported by a pair of wheels which are rotatably supported by a housing for rotation about a central axis. A pair of upper and lower cams are fixed to the housing and cam followers react with the respective cams. Each cam transmits forces through a pair of hydraulic pistons. One of the pistons is connected to a movable plate to which one end of the wires are connected whereby a stress is applied to the wires to strain the wires during a first phase and whereby the cam responds to the unstraining of the wires during a second phase.

  • Patent number: 4195622
    Abstract: A swimming pool cover having at least a portion of which is made of material allowing solar energy to pass therethrough coacts with a solar heating mat in the pool to retain heat developed by the mat. The dark-colored mat has a specific gravity sufficiently greater than that of water to allow the mat to sink to the bottom of the swimming pool. The mat is made of a pliable material and has a crossbar member to facilitate rolling of the mat so that the surface area of the mat may be varied in order to provide control of the temperature of the water. A cylindrical air sac is connected to the cover, which is made of pliable material, and is positioned adjacent an edge of the cover in order to allow rolling and unrolling of the cover and is sufficiently buoyant to support the cover in the water when the cover is in rolled and unrolled positions and during movement therebetween.

  • Patent number: 4190712
    Abstract: An impact energy-absorbing, low density urethane foam for use in automobile bumpers has good moldability and is relatively temperature insensitive, i.e. gives approximately the same physical performance over a wide range of temperatures. This foam is characterized by its good multiple impact performance and low compression set values. The foam is water blown in a closed mold from a quasi-prepolymer system. The molded density is preferably in the range of 5 to 10 PCF.The foam formulation is based on a polymer polyol of a poly (oxypropylene/ethylene) triol reacted with a styrene/acrylonitrile monomer mixture which triol thus modified is reacted with (1) a roughly 1/5 to 1.5/1 weight amount of a hydroxy terminated polybutadiene homopolymer based on polymer polyol, (2) a 50 to 150 equivalent weight polyol crosslinker of 2 to 6 functionality, (3) a MDI glycol or triol quasi-prepolymer, and (4) some water.
