Patent SE-7408030-L (SE)
Inventor: HUG A
IPC: G01R21/00
Filed: 1974-06-18
Abstract: An apparatus and method are described wherein the apparent power fed to an alternating current consumer is measured by an active power measuring device or counter through which the current passes and which has a separate voltage input fed from an amplifier having two inputs. The first amplifier input receives a constant, limited auxiliary voltage which is induced from the current path and in phase with the consumer current. The second amplifier input is used for continuously adjusting the auxiliary voltage in accordance with the instantaneous value of the consumer voltage. For this purpose a comparing device, such as a bridge circuit, may be provided for comparing the consumer voltage with the voltage applied to the power measuring device. Variations in the comparison control can be transmitted, for example, by a small electric motor or a sample and hold circuit which in turn controls a solid state or other variable resistance device connected to the second input. In a further alternative, the second amplifier input may be a field plate which is subject to an electromagnetic flux controlled in accordance with the comparing device. In another example, a voltage divider is connected across the consumer voltage and has a center tap connected through a transistor to the second amplifier input.

Abstract: Measurements of the instantaneous flow of heat delivered to the vapor generator and the quantity of vapor flowing momentarily through the contact heating surface are made and the resultant signals are compared by subtraction or division to obtain a comparison signal. The comparison signal is then imposed on a control element in the form of a valve to cause an injection of more or less water into the vapor flowing into the heating surface in order to regulate the exit temperature of the vapor.

Abstract: Soot produced in the combustion of fuel oil contains valuable metals, such as vanadium and nickel. The soot can be disposed of, and the valuable metals can be recovered, by leaching the soot with an aqueous solution of sulphuric acid, to extract part of the metal content from the soot, combusting the soot thus leached, and leaching the combustion residue with an aqueous solution of sulphuric acid, to extract an additional part of the metal content. The solution produced in this second leaching process is preferably returned to the leaching of the soot. Metals can be recovered in a way known per se from the solution produced in the leaching of the soot.

Abstract: In a hydrostatic support member with at least one pressure pocket in the head portion of the support member, the or each pressure pocket opening opposite a surface which is to be supported, the inner side of the lining wall which defines the pressure pocket relative to the environment of the support member is inclined relative to the pressure axis of the support member, so that the profile of the pressure pocket becomes larger towards its base. The outside of the lining wall extends relative to the inner side in such a way that when this wall is lowered towards the base the hydrostatically effective surface of the head portion, facing the surface which is to be supported, increases in size. A method of producing or finishing the support member according to the invention is proposed: The support member is first prefabricated with the head portion having a relatively small hydrostatically effective surface, compared with an operational one, the walls having been made higher. It is then used under conditions which simulate actual operation. The prefabricated walls of the at least one pressure pocket being so lowered by a lapping type process. As the hydrostatically effective surface of the head portion increases in size during this lowering, the lapping stops automatically at the stage when the optimum operational hydrostatically effective surface for the head portion has been obtained.

Abstract: A mechanical and electrical pressure sensor wherein the mechanical part includes a fluid pressure chamber with a magnetic, electrically conductive diaphragm moving out-of-contact with a stationary contact in the presence of pressure and into contact therewith in the absence of pressure or because of energizing of a cooperatively acting magnetic coil. The electrical circuit connected to the coil includes a clocked flip-flop, the output of which is high during a time interval when the contacts are open (coil energized) and which is low when the contacts are closed (coil deenergized). The duty cycle of energized time to total time is a measure of average coil winding current, and, hence, sensed pressure. The ratio of energized intervals to total intervals develops a useful digital measurement of pressure readily useful in a computer.

Abstract: In reversible compressed air rotary motors for compressed air tools, particularly for wrenches, it is known to discharge the waste air radially from the casing of the motor, which results in a considerable nuisance, in particular as regards noise. Furthermore, due to the close positioning of the compressed air inlet and air outlet, poor efficiency is achieved. To avoid those drawbacks in a rotary sliding vane motor having an elliptical working chamber, the rotor end over on the inlet side is rotatably mounted, and air outlet means is arranged axially and lies in both the clockwise as well as in the antic-clockwise direction or rotation of the rotor relative to the major semi-axis of the elliptical working chamber. Thus by rotating the end cover to one or other of its limit positions, the outlet means communicate with different pairs of passageways.
