The invention relates to a method for increasing the storage stability of sodium percarbonate (2 Na.sub.2 CO.sub.3.3 H.sub.2 O.sub.2) by coating with a sodium perborate.According to the present invention wet sodium percarbonate salt, obtained by reacting sodium carbonate with hydrogen peroxide in aqueous phase and separating the salt from the aqueous phase, is treated with a solution or suspension containing sodium perborate in a solid-liquid separator by a kind of displacement wash. In contrast to previously known methods, according to the present invention a greater storage stability is attained with smaller quantities of perborate coating.

摘要:
A forging machine has four forging rams (2) supported by the machine frame (1) for movement radially towards and away from the system axis (5) in an X arrangement at 90.degree. to one another. Piston and cylinder units (12-15) on the machine frame each have a ram (2) as a constituent part and have a stroke corresponding to the working stroke of the ram. A crosshead (16) supports each piston and cylinder unit, and is adjustable (23-25) relative to the machine frame for setting the stroke position of the ram. An adjustable die holder (6) at the radially inner end of each ram adjusts a die (5) thereon in a direction transverse to the radial direction of the ram, so that the dies can be positioned with parts of their working surfaces overlapping side surfaces of adjacent dies to form a closed forging pass contour smaller than the working surfaces of the dies. Radially extending drive shafts (58) external to the rams and gear units (54-59) at the radially inner ends of the shafts adjust the die holders. Each gear unit is attached (57) to the associated ram, and a rotary coupling (60) is provided between each gear unit and a shaft drive device (63) for facilitating the die holder adjustment dependent on ram radial movement.
摘要:
A forging manipulator for a forging machine is moved longitudinally by a rack and pinion mechanism comprising a pair of longitudinal guide rails on opposite sides of the manipulator, and respective toothed racks associated with these guide rails, the toothed racks being inclined inwards (in cross section), and the manipulator carriage being provided with a respective travel drive for meshing with each rack, the travel drives similarly having their axes inclined to the horizontal.
摘要:
A process and apparatus is provided for the production of calcium silicate-containing stone blanks which are useful in constructing building walls. A crude mixture, of a granulated silicate-containing material, lime, water, a cement and a foaming agent, is subjected to no more than a minimum application of external pressure and is subsequently hardened in an autoclave. The cement produces the necessary strength for the blank, so that the latter becomes transportable while the final strength is achieved by reaction of the silicate-containing material during the autoclave treatment. In order to arrive at acceptable molding times and in order to achieve a simplified process with slight fragment bulk density and optimal head damping characteristics, the crude mixture is rendered pourable, is filled into molds in a quantity corresponding to the fragment volume of the stone blank, and the crude mixture in the mold is heated essentially uniformly to a temperature between 45.degree. C. and 90.degree. C. until achieving the desired blank-strength.The production of the blanks is carried out in molds, which are equipped with a heating system for heating the crude mixture in the molds, whereby the heating takes place by means of an electric high frequency field and/or indirectly via the molds and possibly via mold spikes, which are individually heatable and serve for the development of a pattern of holes in the stone.
摘要:
A vacuum brake booster and a method of operation of a vacuum brake booster of a vehicle brake system is disclosed. The vacuum brake booster includes a housing subdivided into at least one vacuum chamber and at least one working chamber. The vacuum chamber is connected to a vacuum source by way of a vacuum port. A sensor unit is associated with the vacuum chamber and is configured for sensing a pressure in the vacuum chamber and supplying a sensed pressure value to an electronic control unit (ECU). The ECU includes an evaluating unit for evaluating the sensed pressure value and calculating the operating point of the vacuum brake booster solely on the basis of the sensed pressure in the vacuum chamber. Plausibilization of the sensed pressure value is performed to monitor the overall system and identify defects of the sensor unit or the vacuum brake booster.
摘要:
Impending rollover events are detected based on vehicle roll rate, roll angle and lateral acceleration, and an assessment of the relative polarities of vehicle roll rate and lateral acceleration. When the vehicle roll rate and lateral acceleration are opposite in polarity, the roll rate vs. roll angle thresholds used to distinguish between rollover events and non-rollover events are more sensitive than for conditions for which the vehicle roll rate and lateral acceleration are of the same polarity. Additionally, the roll rate vs. roll angle thresholds are adaptively modified based on roll angle and lateral acceleration to provide increased detection sensitivity under conditions that typically precede a rollover event, and reduced detection sensitivity under conditions for which a rollover event is unlikely.
摘要:
A vehicle rollover sensing apparatus and method are provided for predicting a future roll angle and an overturn condition of a vehicle. The apparatus includes an angular accelerometer for sensing angular acceleration of the vehicle and producing an output signal indicative thereof. A first integrator integrates the sensed angular acceleration signal and produces an angular rate. A second integrator integrates the angular rate and generates a current roll angle. A predictor predicts a future roll angle as a function of the sensed angular acceleration, angular rate, and current roll angle. A comparator compares the predicted future roll angle to a threshold value. The apparatus generates a vehicle overturn condition signal based on said comparison, and signals deployment of restraint devices.
摘要:
An apparatus and method that make use of electromagnetic energy to maneuver an object, such as stop, slow, and/or divert a vessel or projectile in low and zero-gravity environments. The apparatus comprises an element capable of generating a magnetic field in the zero or low-gravity environment, and an object capable of electromagnetically interacting with the magnetic field so that the object's speed and/or trajectory is altered when moving in proximity to the magnetic-field generating element. As such, the method entails maneuvering an object in a zero or low-gravity environment by generating a magnetic field in the zero or low-gravity environment, and then moving the object in proximity to the magnetic field such that the magnetic field alters the trajectory and/or speed of the object.
摘要:
A device and a method for controlling an engine. On the basis of a first variable which characterizes the injection quantity and a second variable which characterizes the angular position at which the injection quantity is metered, a third variable which characterizes the torque supplied by the engine is determined. Furthermore, on the basis of a fourth variable which characterizes the driver's intent, a fifth variable which characterizes the torque desired by the driver is determined. The third variable and the fifth variable are analyzed for the purpose of fault monitoring.
