Abstract: ABSTRACT OF THE DISCLOSURE     An actuatable member of a pintle assembly is slidably movable along an axis for movement relative to a reel-carrying cradle support member between reel engaging and disengaging positions.  Compression springs are used to urge the actuatable members of the illustrated embodiments toward the reel-engaging positions.  Locking devices, which can move between locking and releasing positions, are each arranged to directly cooperate and block the movement of an actuatable member to a disengaging position thereof in the locking position of the locking device.          The locking devices may include blocking elements such as rigid displaceable balls or pins, or may include cam arrangements and the like.  A fluid pressure system is provided to act at least on the locking devices and release the same when fluid pressure is applied.  Advantageously. the fluid pressure system also acts on the actuatable member to move the same to the reel disengaging position upon release of the locking device.  The described embodiments provide fail-safe operation during reel engagement independently of the fluid pressure provided by the fluid pressure system.

Abstract: ABSTRACT OF THE DISCLOSURE      A tapered shank ball stud, as used in an articulated joint assembly, has its tapered shank secured in seated engagement in the tapered aperture of a support member in such an assembly by a lock nut threaded onto the externally threaded end of the ball stud with a collapsing washer of original C-shaped annulus configuration sandwiched between the number and the lock nut, the washer being operative as the nut is driven onto the ball stud to effect axial movement of the ball stud to fully seat the tapered shank portion thereof in the tapered aperture in the support member thereby preventing rotation of the ball stud as the lock nut is torqued down to effect collapsing of the washer into a final flat ring-like washer configuration.

Abstract: ABSTRACT In a process according to the present invention pre-reduced lateritic ores containing iron and nickel are leached with an aqueous sulphuric acid leach liquor containing or into which is introduced in the presence of the ore a peroxidant selected from hydrogen peroxide and peroxymonosulphuric acid.  By so doing, the liquor is obtained with a lower concentration of iron than if the peroxidant had not been employed.      In preferred embodiments the leaching is carried out at from 40 to 70°C for a period of I to 5 hours; when hydrogen peroxide is used, it is preferably introduced continuously or progressively throughout the reaction period and when peroxymonosulphuric acid is used it is preferably introduced initially.  The acidity of the liquor can be reduced at the end of the reaction to pH3 to 4 to further lower the content of iron in solution.

Title: Low-cost but accurate radioactive logging for determining gas saturation in a reservoir

Abstract: LOW-COST BUT ACCURATE RADIOACTIVE LOGGING FOR   DETERMINING GAS SATURATION IN A RESERVOIR                   ABSTRACT OF THE DISCLOSURE         A method is disclosed for determining gas saturation in a petroleum reservoir using logging signals indirectly related to the abundances of oxygen and carbon nuclei in the reservoir rock.  The first step of the invention is to record first and second logs sensitive to the abundance of oxygen and carbon nuclei, respectively, after the region surrounding the well bore is caused to have fluid saturations representa-tive of the bulk of the reservoir.  A purposeful change is then made in the fluid saturations in the region surrounding the well bore by injecting a liquid capable of displacing sub-stantially all of the original fluids.  The logs are recorded a second time.  The displacing fluid is then itself displaced by brine, and a third suite of logs is recorded.  The total fluid and oil saturations are then determined from differences between respective corresponding logs and from known fractional volume oxygen and carbon contents of the reservoir brine and oil and the first injected liquid.  Gas saturation is then calculated from differences between total fluid and oil satura-tion values.  It is not necessary that the log responses be independent of the material in the borehole, the casing, the casing cement, or the reservoir rock.  It is only necessary that changes in formation fluids content cause proportional changes in log responses.

Abstract: THERMALLY SENSITIVE ELECTRICAL SWITCH                  ABSTRACT OF THE DISCLOSURE          A thermally sensitive switch has a thermally conductive body within which is a chamber into which extends at least one electrically conductive terminal.  Occupying the chamber is an elastomeric body which is expansible and contractile in response to increases and decreases, respectively, in its temperature.  The elastomeric body may be normally conductive or normally nonconduc-tive, but in either event is conductive when in its expanded con-dition.  When in its expanded, conductive condition, the body engages the terminal and is operable to establish a current path through the body to the terminal.  The body may function as an on-off switch or as a rheostat, depending upon the composition of the body.

Abstract: BELT CENTERING AND REPLACEMENT MECHANISM      FOR BELT SANDERS AND THE LIKE                   Abstract Of The Disclosure The front idler roller of the belt sander is mounted by a yoke for swinging movement in a plane con-taining the axes of both the drive and idler rollers and for shifting movement along a path generally toward and away from the drive roller.  A transversely disposed shaft mounted by the tool housing has a cam formation at one end thereof received within an opening formed in the yoke; the cam is captured in this opening formed in part by a cam follower.  The shaft is mounted for axial and rotational movements.  Rotation of a first knob on the other end of the shaft causes the latter to move axially thereby to swing the idler roller for centering of the belt.  Rotation of a second knob, concentric with the first knob and also mounted on other other end of the shaft, causes the shaft to rotate thereby activating the cam for shifting the idler roller toward the rear roller for easy belt replacement.

Abstract: ABSTRACT OF THE DISCLOSURE     A data handling system is described for encoding an input digital data waveform by a pulse code modulation technique useful to obtain optimum packing density for a recording medium.  The encoding technique selects the binary one state of the input waveform for processing and generates an encoded waveform containing sufficient signal level transitions to reconstruct the original input data waveform. The decoding technique examines the transitions present in the retrieved encoded signal and generates decoding indicia sufficient to identify all binary ones in the original digital waveform.  A waveform generator recreates the original encoded waveform using selected clocking signals and the decoding indicia.
