  • Patent number: 6837340
    Abstract: The invention provides a compensation weight for an elevator system, in the form of an extended cable. The compensation weight comprises at least one carrying organ, at least one weighted element, wherein the weighted element contains a mixture of plastic material and at least one of a pulverized metal salt and a pulverized metal chalcogenide with a density about or greater than 2.3 g/cm3, and an extended, flexible sheath. According to another aspect, the invention provides a compensation weight for an elevator system, in the form of a flat cable. It comprises one or more weighted elements, one or more lengthily extended carrying organ, a flexible sheath, and a plurality of hollow spaces encased by said sheath for the reception of the one or more weighted elements and the one or more lengthily extended carrying organ. The at least one carrying organ and at least one weighted element are designed to be separately and respectively in different hollow spaces encased by the sheath.

  • Patent number: 5253737
    Abstract: A full lining operating brake for a heavy duty vehicle is also provided with a parking or auxiliary brake in the form of a heat storing stack of brake plates within the brake carrier of the operating brake and between the carrier and a sleeve connected to the hub upon which the wheel is mounted. A belleville washer spring stack acts upon the stack of plates through a force multiplier disk and is itself relieved to permit the wheel to rotate by the pneumatic displacement of a tube which draws the spring stack away from the brake plate stack.

  • Patent number: 5148778
    Abstract: A combustion chamber assembly for a two-stroke internal combustion engine has, in the upper dead point position of the piston, a space defined between the piston bottom and the cylinder head which is of the shape of a frustum of a right-circular cone or the shape of a right-circular cylinder. Surfaces of the piston bottom and the cylinder head extend tangentially to the wall of the space at 180.degree. offset from one another and are juxtaposed with surfaces of the cylinder head and piston bottom, respectively, defining narrow gaps squeezing fluid flow into this space tangentially form opposite directions to induce a vortex in the space in a single sense. The fuel injector opens axially into this space for autogenous ignition or self-firing or a spark plug extends axially into this space for external ignition.

  • Patent number: 4309167
    Abstract: The cable is introduced into a sealing tube containing elastic sealing elements before entering the vulcanization chamber which is separated from the extruder. The elements have closed chambers which can be individually pressurized by, in each case, one line, while pressure regulation takes place by means of pressure reducing valves. Gaps can be provided between the individual chambers and they are filled by the heat transfer medium which brings about the crosslinking of the layer extruded onto cable and which passes out of the intake opening of vulcanization chamber. A leakage flow forms along the entire sealing tube and this passes through the openings of sealing elements and completely fills the annular clearance between the boundary of the opening and the cable, so that any contact between the cable and the sealing elements is at least substantially prevented. The gaps can be filled with a sealing liquid, which then forms the leakage flow instead of or together with the heat transfer medium.
