    Abstract: An electro-hydraulic brake assembly comprises a hydraulic control unit (HCU) body having a top surface and a bottom surface opposite the top surface and defining a master cylinder bore and a pressure supply bore. A fluid reservoir is disposed on the top surface. A primary piston is slidably disposed in the master cylinder bore and configured to supply brake fluid to a wheel brake in response to pressing of a brake pedal. A pressure supply unit includes: a pressure supply piston disposed within the pressure supply bore; a motor located on the bottom surface of the HCU body and having a motor shaft. An actuator mechanism includes a threaded shaft configured to be rotated by the motor shaft, and a nut coupled to the pressure supply piston, together causing the pressure supply piston to translate linearly through the pressure supply bore in response to rotation of the motor shaft.

  • Patent number: 7250196
    Abstract: An exemplary system and method for plasma plating are provided to generate a deposition layer on a substrate. The method for plasma plating includes positioning a substrate within a vacuum chamber, positioning a depositant in a filament within the vacuum chamber, reducing the pressure in the vacuum chamber to a level at or below 4 milliTorr, and introducing a gas into the vacuum chamber at a rate to raise the pressure in the vacuum chamber to a level at or between 0.1 milliTorr and 4 milliTorr. In other embodiments, the gas is not required to be introduced. The method also includes applying a dc signal to the substrate at a voltage amplitude at or between 1 volt and 5000 volts, applying a radio frequency signal to the substrate at a power level at or between 1 watt and 50 watts, and heating the depositant to a temperature at or above the melting point of the depositant to generate a plasma in the vacuum chamber.

  • Patent number: 6858119
    Abstract: An exemplary mobile plating system is provided for performing a plating process using virtually any known or available deposition technology for coating or plating as substrate. The mobile plating system may include a vacuum chamber positioned in a mobile storage volume, an external vacuum pump, and a control circuitry to control the operation of some or all of the operations of the external vacuum pump. The external vacuum pump is positioned in the mobile storage volume when the mobile plating system is in transit, and is positioned external to the mobile storage volume when the mobile plating system is stationary and in operation. The external vacuum pump may be mounted on a skid, and, in operation, the external vacuum pump couples with the vacuum chamber to assist with producing a desired pressure in the vacuum chamber.

  • Patent number: 4712616
    Abstract: A process for reducing scale formation in off-shore production platforms where sea water is used as a water-flooding medium. During production, sea water and connate water interact to make scale forming precipitates. Said precipitates fall out in an oil/water separator. Subsequently, additional sea water is injected as the separated aqueous phase leaves said separator thereby causing additional precipitates to form. Via this method, decreased amounts of scale preventing inhibitors are required.

  • Patent number: 4574886
    Abstract: Viscous oil is recovered from a subterranean, viscous oil-containing formation by a steam flooding technique wherein steam is generated in a downhole steam generator located in an injection well by spontaneous combustion of a pressurized mixture of a water-soluble fuel such as sugars and alcohols dissolved in water or a stable hydrocarbon fuel-in-water emulsion containing an anti clay-swelling agent and substantially pure oxygen. The generated mixture of steam and combustion gases pass through the formation, displacing oil and reducing the oil's viscosity and the mobilized oil is produced from the formation via a spaced-apart production well. Suitable anti clay-swelling agents include metal halide salts and diammonium phosphate.
