Abstract: METHODS AND APPARATUS FOR FORMING WIRE TAPES             Abstract of the Disclosure A tape, which includes a number of parallel-extending, elongated wires of substantially circular cross-section, is formed by subjecting an elongated workpiece to two stages of deformation.  In a first stage, the workpiece acquires an intermediate structure, in the form of a tape composed of a number of parallel-extending elongated elements, each having a cross-section which preferably includes a pair of diametrically opposed, substantially circular, arcuate portions.  The cross-section of each elongated element also includes a non-circular, junction region converging towards the adjacent lateral edge of each adjacent elongated element.  Each pair of adjacent elongated elements in the intermediate structure is joined together along the adjacent lateral edges, by two such junction region, one included in each of the elongated elements of the pair.  The contacting junctions regions preferably meet one another along flat surfaces at approximately ninety degrees angles.  In the second stage of deformation, the intermediate structure is subjected to transverse and preferably substantially lateral, compression forces which serve to deform each junction region into a generally circular, arcuate, cross-sectional shape,  The two stages of deformation may take place one immediately following the other by the extrusion of the elongated workpiece through a suitably configured die having two longitudinally aligned deformation zones.     -i-

Abstract: A B S T R A C T Safety belt retractors are disclosed in the for of spring driven belt rewinding mechanisms.  In some arrangements, a pair of spiral springs act in series or in parallel, one spring applying a constant rewinding torque to a belt storage shaft, the other storing energy when the belt is withdrawn.  A ratchet maintains the stored energy and is disengaged by a screw threaded actuator, which moves coaxially to the storage shaft  when the shaft rotates through a number of revolutions.  The stored energy is released to supplement the rewinding torque of the first spring.  In another arrangement, the ratchet is replaced by an over centre spring assembly.  An epicyclic gear box drives a coil spring anchorage through a given arc to give an over centre action.

Abstract: ABSTRACT         A squeeze bottle containing a liquid product such as antiperspirant and the like, has a dispensing nozzle internally forming a swirl chamber having opposed orifices each having its own inlet.  One inlet is connected with a dip tube that dips into the liquid when the bottom is upright, and the other inlet connects with an air space above the liquid when the bottom is upright.  When the bottle is squeezed, the swirl chamber receives opposed jets of the liquid and air, producing an atomized spray.          When the bottle is inverted, the dip tube opens into the air space formed in the bottom of the inverted bottle, while the other inlet is connected with the liquid so that again opposed liquid and air jets enter the swirl chamber.  However, to prevent the liquid component in the swirl chamber from being excessive relative to the air component, the inlet now receiving the liquid is provided with a check valve which closes when the bottle is inverted while providing for a restricted flow rate of appropriate proportioning relative to the air received through the dip tube.          During upright operation,  the check valve opens so that the flow of air is also in this instance appropriately proportioned rela-tive to the flow of liquid.

Abstract: TITLE           CLOSED SYSTEM FOR TESTING THE CONDITION OF     WELL BORE FORMATIONS FOR CEMENTING         THE PRODUCTION CASING              ABSTRACT OF THE DISCLOSURE          In testing the condition of well bore formations as to fluid flow into and out of the surrounding formations and gas emission therefrom prior to cementing a production casing in the well bore, a testing fluid of a preselected density, such as a salt water solution, is pumped from a source through a treating conduit into the production casing positioned in the well bore.  The testing fluid is circulated down the production casing and up the annulus between the production casing and well bore formations displacing drilling fluid and other materials therefrom.  For an empty well bore the pro-duction casing and annulus are filled with the testing fluid. Samples of the fluids are directed periodically to a gas detector to test for the presence of gas emitted from the formations surrounding the well bore.  Once the well bore is flushed clean, the testing fluid is conveyed through a closed circulating system of conduits to a storage vessel.  The storage vessel is connected by a suction conduit to the pump that conveys the fluid from the source to the well bore. After a preselected volume of fluid is established in the storage vessel and the testing fluid is circulating through the well bore, flow from the source is terminated and the fluid level in the storage vessel is monitored for a lo-8 of fluid into the formations surrounding the well bore or flow of fluid from the formations into the well bore.

Abstract: PULL TYPE AUTOMATIC TOBACCO HARVESTER   AND METHOD OF HARVESTING TOBACCO     ABSTRACT OF DISCLOSURE   The present invention relates to a pull type multi-pass automatic tobacco harvester adapted to be connected to a farm tractor and pulled through a tobacco field for harvesting tobacco within the field.  The pull type automatic tobacco harvester includes a main frame that supports a leaf defoliator assembly and a conveying system on each side thereof for receiving the defoliated tobacco leaves and conveying them to an area of collection.  Connecting the harvester to said tractor is a hydraulically actuated swingable tongue that is pivotably mounted about the front portion of said harvester's main frame.  When pivotably connected to a draw bar on the tractor, said tongue may be pivoted such that the trailing position of the harvester can be laterally varied relative to the tractor such that the defoliator assembly of said harvester can be properly aligned with any one of two adjacent tobacco rows that run along one side of the tractor. To improve the row tracking capability of the pull type harvester of the present invention, the defoliator assembly is pivotably mounted about a longitudinal axis on said main frame and pivotable laterally back and forth about this longitudinal axis.  This allows the row passing area defined within the defoliator assembly to shift laterally with the row being harvested due to variances in row spacing, crooks and curves in the row, and the imprecise positioning of the har-vester about the row being harvested.

Abstract: POSITIONING MEANS FOR CIRCUMFERENTIALLY LOCATING INSPECTION APPARATUS IN A NUCLEAR REACTOR VESSEL            ABSTRACT OF THE DISCLOSURE    Positioning means for locating inspection appara-tus used to volumetrically examine a nuclear reactor vessel is disclosed.  The positioning means is provided with a support ring having an annular key positioned longitudinally about its periphery.  Three support legs are attached to the support ring by brackets adapted to fit the annular key.  In addition, the support ring also carries three guide stud bushings which are movably mounted thereon by clamps adapted to engage the support ring key.  Prior to lowering the inspection apparatus into the vessel, the guide stud bush-ings are each moved to a point of alignment with one of three guide studs extending upwardly from the vessel.  After alignment has been verified, the guide stud bushings are clamped in position.          The inspection apparatus is now lowered towards its fully seated position within the vessel and is coarsely circumferentially positioned with respect thereto by the engagement of the guide studs within the guide stud bushings.          A fine degree of circumferential positioning is achieved by providing a specially configured shoe for one of the support legs.  With the core barrel internals in, the special shoe is adapted to key onto a core barrel pin the exact location of which is known.  With the core barrel internals removed, the special shoe is adapted to place a locating key into a notch in a vessel flange, the location of which is also exactly known.  Thus, as the inspection apparatus is lowered into its fully seated position, exact circumferential posi-tioning thereof with respect to the vessel is achieved.  The other support legs rest on an inner circumferential flange so that no portion of the inspection apparatus touches or threatens the vessel's top flange.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE ALTERNATING VOLTAGE OF A STATIC CONVERTOR     Abstract of the Disclosure An improved reactive power control for a static convertor wherein the improved control compensates for voltage transients caused by the connection and dis-connection of reactance elements in an AC convertor network by making corresponding transient adjustments in a normal control angle of the convertor.  A maximum angular increment in the direction of 90° is applied to the normal control angle when the AC reactance switching occurs.  If a capacitive reactance element is connected to the AC network, the maximum angular increment is rapidly built up after the connection and is thereafter gradually reduced.  If the capacitive reactive element is disconnected from the AC network, the maximum angular increment is gradually built-up prior to the disconnection and after the disconnection the maximum angular increment is rapidly reduced.  The sequence of incremental control angle build-up and reduction is reversed if the reactance element is a reactor.
