    Abstract: Composite materials are in the form of particles, such as bits and short filaments, and combinations of such particles with matrix materials forming high strength, wear and corrosion resistant materials and may be shaped to define cutting tools, dies, mold components, electrodes, bearing components, finishing tools and the like. Structures include substrates and synthetic diamond particles encapsulated therein or bonded thereto have superior grinding, cutting and finishing characteristics. Particles are in the form of microbits, spheroids, single crystals, short narrow filaments and metal whiskers coated with synthetic diamond formed with a core of graphite, metal, metal compounds, metal alloys, ceramic, cermet, glass and composites thereof. Filaments and bits are coated with a lubricating film of wear resistant metal. Methods for producing such composite synthetic materials include the chemical vapor-deposition of carbon atoms from hydrocarbon gas molecules in a high intensity radiation field such as a microwave energy field.

    Abstract: Present day diesel engines having aluminum piston assemblies are limited to combustion chamber pressures of approximately 12,410 kPa (1,800 psi) whereas the desire is to increase such pressures up to the 15,170 kPa (2,200 psi) range. To reach such levels the instant piston assembly includes a steel piston member having an upper cylindrical portion defining a top surface, a depending tubular wall and an annular cooling recess having one or more machined surfaces of revolution about a central axis. The cooling recess is located beneath the top surface and juxtaposed to the top ring groove for removing heat away therefrom in use. The piston member is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly is preferably of the articulated type and includes a forged aluminum piston skirt connected to the piston member through a common wrist pin.

    Abstract: A thermal insulating material for combustion engine components, which are subjected to combustion gases, e.g. pistons. The insulation consists of a metal layer sintered under low pressure so as to have a porosity of about 25-50% and which is bonded to the engine component by casting of the component onto the porous sintered layer. The exposed or wear-receiving surface of the sintered layer is machined, which not only achieves accurate dimensioning but also closes the pores of the surface.

    Abstract: A pump has in a housing a revolvable shaft which drives a piston stroke guide body. Drive pistons are provided with piston shoes which run on the guide face of the piston stroke guide body and drive fluid supply pistons of smaller diameter. The pump preferies a fluid separator between lubricating and non-lubricating fluid, like for example, between oil and water, whereof one of the fluids flows through an inner chamber which is provided with inlet and outlet valves while the outer fluid acts in an outer chamber which is open toward the cylinder wherein the fluid supply piston reciprocates. Dead space fillers are provided to prevent losses by compression of fluid and seal means are assembled to prevent leakage of fluid from one into the other of the chambers. The fluid separator may be compressible and expandable within the plastic deformable range of the material whereof it is made. The pump includes sophisticated technologies which necessiated more than half a decade of intensive research and testing but it is now capable of pumping fluid, including water, of several thousand atmospheres of pressure.

    Abstract: A method for manufacturing a piston of an internal combustion engine, especially for forming a piston gallery portion provided in the piston head for cooling the engine. A gallery member made of a metal pipe having a high thermal conductivity or a salt-core having a shape corresponding to the piston gallery is fixed to a fixing member having a peripheral rim and a plurality of fixing legs extended from the rim. The gallery member or the salt-core fixed to the fixing member is cast in the piston, body, and then, the fixing member is cut off from the piston body. The salt-core is melted away by pouring water. By this method, a piston of light weight and having high cooling efficiency can be manufactured.

    Abstract: Light-metal piston for combustion engines, having a sleeve-like insert embedded therein and controlling its heat expansion and being formed of a metal of smaller heat expansion coefficient than the piston base material. The insert is arranged in the solid material of the piston crown and extends around the entire piston periphery. Behind the insert, the piston base material is self-contracted to form a gap delimited by the insert on one side. On at least one edge or one side, the insert is not covered by piston base material, i.e. it extends up to the piston surface, this occurring however only in certain segments and not along the entire piston periphery. In the other segments, the insert lies beneath the piston surface and is thus covered by piston base material. To the extent that the insert is exposed on the piston end face, it is provided with an edge zone covering the depth of the self-contraction gap.
