Abstract: A lead-acid battery is disclosed. The lead-acid battery has a container with a cover and includes one or more compartments. One or more cell elements are provided in the one or more compartments. The one or more cell elements comprise a positive electrode, the positive electrode having a positive substrate and a positive electrochemically active material on the positive substrate; a negative electrode, the negative electrode having a negative substrate and a negative active mass on the negative substrate, wherein the negative active mass comprises a leady oxide, a synthetic organic expander, a very fine particle barium sulfate, and plurality of conductive carbons; and an absorbent glass mat separator between the positive plate and the negative plate. Electrolyte is provided within the container. One or more terminal posts extend from the container or the cover and are electrically coupled to the one or more cell elements.

Abstract: Disclosed is a method for depositing a film onto a substrate, with a sputter deposition process wherein the sputter deposition process is a direct current sputter deposition wherein the film consists of at least 90 wt-% of an inorganic material having semiconductor properties whereby the film of the inorganic material M2 is directly deposited as crystalline structure, so that at least 50 wt-% of the deposited film has a crystalline structure wherein the source material (target) used for the sputter deposition consists of at least 80 wt-% of the inorganic material M2. wherein the inorganic material is selected from a group including binary, ternary, and quaternary compounds including sulphur, selenium, tellurium, indium, and/or germanium.

Abstract: A device for cooling the pistons of an internal combustion engine by a lubricating oil pump which supplies oil from the lubricating oil circuit to at least on the base side of each piston through at least one supply line having an outlet opening and at least one valve. The at least one valve is a check valve which does not permit oil to be supplied until after a defined pressure is achieved in the lubricating oil circuits and a control unit regulates the lubricating oil pump so as to provide variable pressure in the lubricating oil circuit as a function of engine load.

Abstract: The invention provides a cooling system having an electrically adjustable control element for influencing the coolant temperature of internal-combustion engines in motor vehicles. The system according to the invention has an electronic controller which is connected in front of the control element and which, at least as a function of a quantity influenced by the coolant temperature, generates the control signal quantity for the control of the control element for reaching a desired coolant temperature. The parameters of the controller are determined by means of a basic characteristic diagram and at least one characteristic correction diagram.

Abstract: A pair of hydraulic clutches, serving to connect an input shaft with either of two nested output shafts coaxial therewith, comprise a common die-cast annular carrier in the form of a generally cylindrical sleeve whose inner and outer surfaces are integrally formed with peripherally spaced first and second ribs for the guidance of a first and a second set of annular friction foils, respectively. The carrier has an inner radial flange forming an abutment for one of the friction foils of the first set, the second ribs being axially offset from the first ribs and extending beyond that flange in the form of peripherally separated prongs. The inner sleeve surface diverges outwardly from the region of the flange, with a slight draft as needed for casting; at its wider end the sleeve is fastened to a similarly produced first clutch housing accommodating a first piston normally held spaced apart from the first friction foils by a Belleville spring inserted between the sleeve and that clutch housing.

Abstract: A centrifugal governor on a rotating shaft has a mounting rigid with that shaft, the latter being journaled in a housing wall from which a stationary hub extends into a central bore through which a hydraulic fluid is admitted to an inlet port of a valve controlled by the governor, the outlet port of that valve communicating with a clearance provided between the hub and the shaft which opens into an outgoing channel in the hub.
