Patent JP-S5924732-B2 (JP)
IPC: C25B1/00
Filed: 1980-02-26
Abstract: The invention concerns a process for the recovery of the uranium contained in an impure phosphoric acid. The impure acid is treated with an organic phase capable of extracting U (VI), and the resultant organic phase is then re-extracted with an aqueous solution containing complexing acid and an oxidizing-reducing agent in the reduced state, said oxidizing-reducing agent being capable of reducing U+6 to U+4 in said aqueous solution. The resultant aqueous phase is then subjected to electrochemical oxidation, followed by extraction with a second organic phase from which the uranium is recovered, the depleted aqueous solution being recycled to the re-extraction after electrochemical reduction, with the process comprising two organic phase cycles and a cycle of a complexing aqueous solution. The process is of particular interest when applied to the recovery and concentration of uranium contained in a wet process phosphoric acid.

Abstract: A ceramic unit for replacing lost substance or tissue and having a contour transferred from a preparation model or a replacement position is made of densely sintered ceramic material. The model contour in question or a corresponding contour is transferred in a linearly enlarged state to a part (4) belonging to a press tool (6), whose enlarged contour (2 min ) defines a mould cavity (5) formed by means of the part in the press tool. Ceramic starting material is applied in the mould cavity and is subjected to compressive force. The unit produced in this way is released or removed and is treated in one or more sintering procedures in which it is subjected to linear shrinkage until the contour defined by the tool part has essentially the same size as the model contour. It is proposed that Figure 2 accompany the abstract.

Abstract: A chronometric indicator for a watch has concentric arrays of angularly equispaced electrodes and analog display segments. The electrodes are staggered relative to the display segments so that each electrode overlaps halves of two adjacent segments, so that by selective energization of the electrode and the segments any half can be optically activated. In addition a digital display is provided within the two annular arrays, with each digit segment of the display being connected to a respective analog segment. A common connection for this digital display can be energized simultaneously with any of the outer analog segments to cause the corresponding digit segment to glow. The overlapping arrays of electrodes and analog display segments are energized to indicate the hour and minute, and the digital display is energized to indicate the second.

IPC: F16C3/02
Filed: 1981-06-17
Abstract: A method of applying a layer of resin and axial fibres to a workpiece such as an automotive propeller shaft during the manufacture of the shaft includes the steps of arranging a series of fibre feed stations around the periphery of the workpiece, causing the fibres from the feed stations to converge along a conical path with the workpiece where they are united with the workpiece by circumferentially wrapped fibres. Resin is applied to the cone of fibres by throwing it out under centrifugal force from a rotating annular groove when the fibres are sufficiently close together to support a layer of resin between adjacent fibres. As the fibres are then pulled on to the workpiece, good impregnation of the resin into the fibres is achieved.

Abstract: This invention relates to a control method and a circuit for MOS-gated power semiconductor switching devices such as IGBTs or MOSFETs, which allows control and optimisition of the current and voltage commutation of a power semiconductor switching device and freewheel diode pair in the basic half-bridge circuit found in a wide range of equipment. The method comprises the stages of: applying, upon receipt of a switch-on command signal, a voltage function to the control terminal or the gate of the power semiconductor switching device that allows a regulated current rise in the device whilst maintaining the voltage across the device falling at a predetermined rate; and at the instant when the voltage across the diode begins to change from the on-state towards the off-state level, applying a voltage function to the control terminal or the gate of the power semiconductor switching device to enable the voltage falling across the power semiconductor switching device to track the voltage falling across the diode in order to ensure a fast and controlled completion of the switching operation without diode reverse voltage overshoot. The gate drive automatically modifies the voltage function according to the working condition thereby accounting for the actual operating conditions.

Abstract: A construction module is described, one side of which has four slightly resilient spring leaves (6, 6') which are arranged in a tulip shape and can easily snap onto the other five side faces (2 to 5) of an identical construction module. The side faces have strips (8, 8') which can be continuous or interrupted. On the inside, the spring leaves are provided with corresponding connecting elements (7, 7', 7'') which engage behind the said strips. A connection is produced between two construction modules firstly by slight deflection of the spring leaves from their position of rest and by subsequent engagement behind the said strips. The construction modules have the advantage that they can be connected to one another or detached from one another easily and reliably even after a long time and frequent use. <IMAGE>

Abstract: A device for withdrawing from a bar pusher and thereafter unloading the crop-ends of the metal bars in a bar feeding apparatus for a multi-spindle lathe, said device being suitable also for placing a new bar on said bar pusher, is disclosed.The device of the invention is comprised essentially of a pair of movable jaws which by means of a turning movement close onto the crop-end of a metal bar and lock said crop-end therebetween. Said crop-end is the residual part of the lathe machining of the metal bar.Thereafterthejaws accomplish a translation movement to detach the crop-end from a bar pusher which formerly caused the bar forwarding in the feeding apparatus of the lathe. The jaws thereafter open slowly dropping the crop-end in a proper unloading zone. Finally the jaws close onto a new metal bar to be machined and, by means of a further translation movement in the direction opposite to the former one, perform the insertion of the new metal bar end into the bar pusher.

Abstract: A rolling or folding doorway shutter, for use e.g. in an industrial or commercial building, consists of vertical supports (1,2) on either side of the doorway, connected by a cross member (3) at the top. Each support contains a slider guide for the door shutter (4) which is roller or folded at the top. The shutter is reinforced by a number of horizontal bars (5) which have their ends moving in the sliders. At least one of the bars has a flexible section (e.g. spring-loaded and telescopic) which enables it to jump out of the slider in the event of an abnormal transverse effort being applied to it, without creating any permanent deformation in the bar which might ultimately affect the operation of the shutter. The bar's flexibility can be provided in the centre or at one or both ends, and the slider containing the flexible bar can have a branched track to allow for the replacement of the bar once it has been deformed.
