Abstract: Abstract Low Cycle Fatigue Crack Elimination For Integrally Bladed Disks Stress relief for the rim of an integrally bladed rotor made from a forging preform is provided by forming a plurality of radially extending circum-ferentially spaced-apart slots around the periphery of the preform.  The slots are forged closed in a subsequent forming step.  An oxide layer on the slot surfaces prevents the surfaces from bonding together when forged closed.  The blades are formed between slots during the forging or by machining after forging.

Abstract: ABSTRACT         The apparatus and method of this invention pro-vides for the automatic, inline string-up of a rapidly advancing filament, particularly a glassy alloy strip, from a high speed continuous casting operation onto a rotating winding wheel.  A take-up head comprised of two counter-rotating brush rollers having selectable inter-ference and speed of counter rotation captures a leading segment of the advancing filament.  The brush rollers are mounted on a carrier arm pivotable about the rotational axis of the winding wheel.  As an actuator mechanism pivots the carrier arm, the brush rollers move around the winding wheel to contact a segment of the filament with the winding surface of the wheel.  A cut and grip device then cuts the filament at the winding surface and secures the filament to the winding wheel.  Thereafter, inline winding of the filament proceeds.

Abstract: Abstract A thermal servo-motor, particularly for valves comprises two operating elements (4, 5), particularly bellows boxes, acting oppositely on an actuating bridge.  Each operating element is connected to a container (35, 36) containing the medium (37, 38) of a filling that determines the pressure.  The connection is by way of an intermediate member (39, 40) which has a passage and which at least partially thermally insulates the operating element and container from each other.          The container space is small relatively to the smallest volume of the operating element (4, 5).  A tempering apparatus (41, 42) is associated with the two containers (35, 36).  In this way, one can produce the desired vapour pressure in the operating elements with respectively little heat power.  The servo motor can be rapidly adjusted.     Fig. 1.

Abstract: WETTABLE DEVICES OPERATIONAL    WITH AQUEOUS LIQUIDS            Abstract A humidifier (10) used in respiratory therapy is disclosed where the surface tension of a light probe (32) used therewith is maintained greater than the surface tension of the aqueous liquid used in the humidifier (10).  Maintaining the surface tension of the light probe (32) greater than the surface tension of the aqueous liquid generally avoids erroneous indication of aqueous liquid level in the humidifier (10),  Erroneous indica-tions of liquid level can be caused by gas bubbles adhering to submerged portions of the light probe (32) or liquid droplets adhering to unsubmerged portions of the light probe (32).  Sur-face tension of the light probe (32) can be maintained greater than surface tension of the aqueous liquid by coating the light probe (32) with a surface active agent, by subjecting the light probe (32) to corona discharge or plasma treatment, by coating the interior surface of the humidifier cannister (14) with an amount of surface active agent, by adding an amount of surface active agent to the aqueous liquid in the humidifier (10) or by any combination.

Abstract: ABSTRACT            JOINTING OR TERMINATING ELECTRIC CABLES     A tubular insulating sleeve is prepared ready for fitting to an electric cable (for jointing or terminating that cable) by inserting an elongate member 16 into the sleeve so that the elongate member 16 projects from or terminates adjacent one end of the sleeve (for example abutting a mandrel 14), the elongate member 16 being of smaller diameter than the internal diameter of the sleeve:  then the sleeve is progressively rolled upon itself, starting from its said one end, the rolled up portion of the sleeve gripping the member 16 and the remainder portion of the sleeve being free to slide along the member 16.  A tubular carrier 12 may be disposed within the sleeve before the rolling process, the carrier 12 sliding on the member 16 as the rolling progresses and the roll finally being rolled onto the carrier:  successive stages in the rolling process are shown at (a), (b) and (c) in the drawing.

Abstract: INVENTOR:  HEINZ GUTTINGER INVENTION. METHOD  FOR ROLLING METAL FOILS     ABSTRACT OF THE DISCLOSURE           In rolling metal foils, such as aluminum foils, especially very thin foils in the range down to 10 µm, an improved uniformity of the foil thickness over the width of the foil sheet and, simultaneously, greater rolling speeds of the  foil sheet are obtained by operating the rolling apparatus  at  a  working  point  of  the  rolling force/material-working   or   line   force/deformation characteristic curve which lies below the saturation region in which, while the material-working or deformation is nearly independent of the rolling or line force, the rolling or pulling speed is determined by other parameters and can not be varied.  The thickness variations occurring under this selection of the working point and due to variations in the rolling or line force over the width of the rolls are compensated by regulating the rolling or line force such that the thickness reduction is constant over the width of the sheet or has a desired profile of variation.  This can be obtained by, for instance, constructing one or more of the rolls as a controlled deflection roll provided with a series of pressure or support elements having regulatable pressing forces distributed over the width of the roll.

Air or another relatively inert gas is mixed with molten thermo-plastic adhesive, and the mixture is pressurized to form a gas and molten adhesive "solution".  When the molten adhesive and gas "solution" is dispensed at atmospheric pressure, the gas is released from "solution" and becomes entrapped in the adhesive in order to form a homogeneous closed cellular adhesive foam.          In order to control the gas content of the dispensed adhesive and gas "solution", the pressure drop across a restriction in the flow path of the solution is sensed, and a control circuit controls the addition of gas to the adhesive to maintain the sensed pressure drop at a desired level.

Abstract: ABSTRACT OF THE DISCLOSURE          Ferric nitrate leaching at 75°C is found to remove up to 97% of the uranium and 93% of the radium from ores occurring in the Elliot Lake area of Canada, after an initial flotation-separation of the sulfide minerals from the ore.  In processes of the invention an aqueous acidic ferric nitrate solution of relatively low concentration, e.g. 0.01M to 0.1M is used, giving tailings which are effectively sulfide-free (less than 0.45 wt%) and with radium levels approaching a desired maximum value of 24 pCi/g.  Radium may be removed from the leachate by adsorption and uranium by solvent extraction.  80-87% of the ferric nitrate may be recirculated for further leaching.  Because of the low reagent concentrations and the recycle of the ferric nitrate, it is possible to keep nitrate ion levels in the effluent below the prescribed level of 10 ppm.
