Patent BR-0108596-B1 (BR)
Inventor: BARLAS SERGE A
IPC: B60G9/00
Filed: 2001-02-15
Abstract: A method of welding an axle connection device (100) to a face of an axle housing (102). The method includes forming two continuous welds (160,162) along both longitudinal edges of the device (100). Each weld (160,162) begins longitudinally inward of one of the rounded corners (140,142) of the device, preferably one of the rounded corners (140) positioned closest to the spindle end of the axle. The weld (160) is formed such that it extends longitudinally outwardly towards that rounded corner (140) to a weld end (166), which is positioned longitudinally inward of that corner (140). The weld (160) is then turned back on itself and extends longitudinally inwardly along the tapering slope of the end of the device towards the waist portion (136) thereof to form a double-pass weld at its end. The weld then extends through the waist portion (136), then longitudinally outwardly along the tapering slope of the opposite end (142) of the device (100) to a point just shy of the rounded corner (142) at that end. At that point, the weld (160) is again turned back on itself to form a double-pass weld at its end. The weld (160) is then terminated. Another continuous weld (162) is made in like fashion along the opposing longitudinal edge of the device. Under this method, substantially less weld is used and the weld lines do not traverse over, along and/or around the rounded corners (140,142) of the device. As a result, the axle housing (as opposed to the weld runs) primarily absorbs any torsional loading.

Abstract: A system and process for producing xylene and other alkylated aromatics includes one or more fluidized bed reaction zones that provide contact between the reactants (i.e., an aromatic reactant and an alkylating reagent). Improved conversion and selectivity is realized when the alkylating reagent is stagewise injected into the fluidized bed at one or more locations downstream from the location of aromatic reactant introduction into the fluidized bed. Preferably, the alkylating reagent is introduced at a plurality of locations along the axial direction of the fluidized bed reaction zone, or at plural locations between a plurality of different fluidized bed reaction zones.

Title: Division of binary coded two position dividend - by binary coded in position divisor based on iterative subtraction method
IPC: G06F7/52
Filed: 1974-08-10
Abstract: Divisor and dividend are stored in a n or Zn position register. During the whole division process, an interrogation circuit monitors the result of a subtraction with regard to the binary value of the sign. The interrogation circuit (AS) is designed, so that in the event of a positive sign (V = O) of the actual result of a subtraction, it induces the direct entry in one part (A1) of the register (A1, A2) intended for the n higher value positions. In the case of a negative sign, the interrogation circuit induces merely a displacement of the original contents of the register (A1, A2). The counter (Z) position is reduced by one unit for each register step.

Abstract: The system allows the engine to operate in a homogenous fuel mode or a stratified fuel mode.  The system provides control of the internal combustion engine (10) in a vehicle. The engine is operated selectively in two combustion modes - one in which it uses a homogenous fuel-air mixture, and the second in which it uses a stratified fuel-air mixture. A control is provided for stopping the supply of fuel to the motor (10) when the engine is required to decelerate, and a further control reduces the couple in order to reduce the output torque of the engine prior to stopping the fuel supply to the engine. If the selected combustion mode is the stratified mode, the couple reduction device reduces the output couple provided by the engine to achieve a lower level, by reducing the quantity of injected fuel to the minimum which the fuel injector is capable of injecting. A fluid transmission system is used to link the output drive of the engine to the road drive.

Abstract: A pneumatic sanding machine for cleaning and scraping replaces a sanding disc with a high pressure compressed air disc swirling powder abrasive. Acceleration and ejection functions of the sanding nozzle are dissociated in two portions, allowing very thin ejection ports, even smaller than 400 micrometres in diameter, without clogging. The nozzle acceleration channel common to all ejection ports emerges on an anti-splash cone that bursts the jet of compressed air/abrasives exiting the nozzle, directing the air-abrasive flux towards tungsten carbide ejection members. Thus, the ejection ports are holes/slots drilled in tungsten carbide boards inserted in a disc/platen. The disc/platen may be driven to rotary speeds (RPM) obtained using a mini-turbine of 1,000-20,000, possibly exceeding 30,000, but generally 4,000-12,000, enabling high pressure work. The weight, space and manoeuvrability allow the tool to be directly adapted on the arm of an industrial robot and sanding aircraft flight deck and automotive bodywork, etc.
