Abstract: Abstract An improved chuck wrench for contra-angle dental handpieces.  The wrench includes a unitary angular C-shaped body, one of the arms of the body being provided with a socket and recess for accurately locating the wrench in position relative to the head of a handpiece when chuck adjustment (or removal) is desired.  Between the paired arms is a knurled cylindrical wheel dimensioned to fit comfortably between, and be rotated by, the same fingers that receive the narrower connecting portion of the C-shaped body.  A torsion spring shaft extends through the wheel and into the socket and has an end portion having a torque transmitting periphery which is receivable within a corresponding opening of a hand-piece chuck for locking the two parts (chuck and shaft) against independent relative rotation.  A shoulder of the shaft limits the extent that the end portion may be inserted into the chuck opening, and the substantial length of that shaft, and its relationship with the other parts of the wrench, result in a torsional flexure of the shaft upon chuck tightening that signals the user when the torque limit is approached.  The shaft, as well as the tangs which engage the burtube of the handpiece during an adjustment operation, are spring-loaded for limited axial movement.

Abstract: DIFFERENTIAL X-RAY METHOD AND APPARATUS            ABSTRACT:        Differential X-ray images are produced in order to improve the visibility of a contrast medium, such as iodine or xenon, having a K absorption edge at a predetermined X-ray energy.  Such differential images are produced by combining first, second and third X-ray images which are individually produced by using first, second and third X-ray spectra at first, second and third X-ray energy levels.  The first energy level is below the K edge energy, while the second energy level is above the K edge energy.  The third energy level is above the second energy level.  The second X-ray image is combined subtractively with the average of the first and third X-ray images to produce a differential X-ray image in which any image elements due to soft tissue and bone are largely cancelled out, while image elements due to the contrast medium are enhanced.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE           A new chemical recovery process for a poly-sulfide pulping system is described wherein sulfur is recovered from the weak black liquor and is returned to the process, along with makeup sulfur, to recon-stitute the polysulfide solution.         After the polysulfide digestion, the spent liquor is contacted with ferric oxide Fe2O3 whereby ferrous sulfide, FeS, is formed.  After separation of the ferrous sulfide from the remaining liquid, the ferrous sulfide is oxidized to form elemental sulfur, and ferric oxide.  After the melting of the sulfur and the separating of the products, the sulfur can be re-turned to the Sulfur Dissolving Tank wherein, along with makeup sulfur as required, the white liquor from the causticizing plant can be treated to form the polysulfide liquor for digestion.  The ferric oxide can by reused for contacting the black liquor to form ferrous sulfide.  The resulting smelt of reduced sul-fidity from the recovery furnace can be reprocessed to form the white liquor.

Abstract: ABSTRACT                 A method and an apparatus for fixing a ring element to the inner wall of a thermoplastic pipe are disclosed.          The invention involves the clamping of the ring element on a cylindrical support member and the combined straightening and radial expansion of the ring element into contact with the inner wall.  Previously, or simultaneously, the pipe is radially expanded stepwise to its final diameter, the apparatus including suitable mold portions which can impart the desired shape to the pipe end.  One part of the mold portion can include radially expandable blockade means which can impart a portion of the desired shape to the pipe end and which can also be instrumental in the clamping and expansion of the ring element.  Use of the invention results in a strengthened pipe end which is sized to mate with the end of a next length of pipe and which has a built-in means for mounting packing or other sealing elements.

Abstract: DUAL FUNCTION HEATER CORE     ABSTRACT OF THE DISCLOSURE     An integrated system for engine heat extraction and comfort air conditioning in an automotive vehicle powered by a Stirling engine, the system being used (a) as a part of the heat rejecting means for the Stirling engine located in a compartment outside of the passenger compartment, and (b) for conditioning air within the passenger compartment.  The heat rejecting means of the Stirling engine is effective to cool a selected zone of an enclosed working fluid circuit of the engine; the heat rejecting means is divided into two portions, one normally being disposed to reject heat to ambient air conditions and another disposed to selectively impart rejected heat either to air flow for conditioning air for said passenger compartment or to air flow to be aborted to ambient air conditions.  The embodiment as disclosed further includes evaporation or heat absorption means and controls therefore to blend dehumidified cooled air with the air warmed by said heat rejection portion to render a total air conditioning system for the passenger compartment which relies in part upon the heat rejection means being continuously employed as an element of the Stirling engine.  In another embodiment, the air conditioning system is arranged with appropriate controls to recirculate cool, dehumidified air to the heat rejection means for a reheating cycle before entering the passenger compartment; an ambient dump control is again employed so that the heat rejection means may be maintained in constant operation.

Abstract: ABSTRACT OF THE DISCLOSURE         Process for producing fluid fuel from coal.  Moisture-free coal in particulate form is slurried with a hydrogen-donor solvent and the heated slurry is charged into a drum wherein the pressure is so regulated as to maintain a portion of the solvent in liquid form.  During extraction of the hydrocarbons from the coal, additional solvent is added to agitate the drum mass and keep it up to temperature.  Subsequently, the pres-sure is released to vaporize the solvent and at least a por-tion of the hydrocarbons extracted.  The temperature of the mass in the drum is then raised under conditions required to crack the hydrocarbons in the drum and to produce, after sub-sequent stripping, a solid coke residue.  The hydrocarbon pro-ducts are removed and fractionated into several cuts, one of which is hydrotreated to form the required hydrogen-donor sol-vent while other fractions can be hydrotreated or hydrocracked to produce a synthetic crude product.  The heaviest fraction can be used to produce ash-free coke especially adapted for hydrogen manufacture.  The process can be made self-sufficient in hydrogen and furnishes as a by-product a solid carbonaceous material with a useful heating value.
