Abstract: FLUXLESS BRAZING OF ALUMINUM IN INERT GAS                 ABSTRACT OF THE DISCLOSURE            A method of brazing aluminum parts in an inert gas atmosphere is disclosed.  The brazed filler metal is controlled to  contain a ternary alloy of aluminum-silicon-magnesium and the base aluminum parts are controlled to contain a binary alloy of aluminum-magnesium.  Magnesium in the base metal is controlled to .4-1.2% and in the filler metal it is controlled to .2-.6%; in the filler metal only silicon is controlled to 7-12%.  The assembled base metal parts and filler metal are subjected to differential heating rates, one rate being limited to at least 50°C/minute when the metal parts reach temperatures in the range of 400-550°C, and a conventional rate when outside said temperature zone.  As a result, three physical parameters are caused to occur simultaneously:  initiation of porosity in oxide film on the metal parts, transport of magnesium to the oxide interface and reaction with the oxide, and initial melting of the filler metal as well as wettings of the oxide by the filler metal.

Abstract: HYDROGEN COMPRESSION SYSTEM FOR STIRLING ENGINE            POWER CONTROL              ABSTRACT OF THE DISCLOSURE      A regenerative Stirling cycle engine system is disclosed.  The system employs piston means associated with fluidly-connected pairs of cycling hot and low temperature gas volumes for varying the low temperature volume in timed relation to variations in hot gas volume.  Reversible thermo-dynamic gas flow between the hot gas volume and the low temperature gas volume during changes in volume is provided by thermal regenerator and cooling means intercoupling the hot and low temperature gas volumes of each pair of cycling volumes.  Thermal energy is released to the hot gas volume and cooling energy is derived from the piston means.  A one-way fluid connection is provided between adjacent low temperature volumes in series   Fluid communication through any two selected and adjacent low temperature volumes is selectively controlled while continuous one-way fluid communication from the selected and adjacent low tempera-ture volumes to a reservoir is permitted.  In this way, if the instantaneous pressure of the reservoir is greater than the communicated low temperature volume, one low temperature spare will pump  fluid into the other to be raised in pressure therein.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved process is provided for the preparation of white liquor for the sulphate pulping process, wherein quicklime is slaked with green liquor and the slaked lime formed is reacted with the sodium car-bonate in the green liquor to produce sodium hydroxide in a causticizing process, the lime sludge so formed when being separated.  According to this invention, water included in green liquor is reacted with calcium oxide and then calcium hydroxide so-formed is reacted with sodium carbonate in the green liquor to obtain sodium hydroxide and calcium car-bonate, each of the above reactions being carried out at a pressure above at-mospheric pressure.  In a preferred embodiment, the process is also car-ried out at a temperature above the normal boiling temperature of liquids in the system e.g. at a temperature of 105-170C.  In this way a number of advantages are obtained.  Since the reaction takes place in a closed vessel the exothermic heat of reaction raises the temperature above 105C. At this higher temperature, lime sludge precipitates as larger crystals, which are easier to separate from the white liquor.

Abstract: ABSTRACT       A catalyst regeneration process and apparatus for the oxidation of coke from a spent catalyst, said coke being con-verted to CO, and for the conversion of the CO to CO2,  Hot regenerated catalyst is recycled from a dense bed in the re-generation zone to mix with incoming spent catalyst in a riser-mixer.  The riser-mixer operates in dense phase and is supplied with a relatively small amount of a fluidizing medium, prefer-ably air.  After the mixing of spent and fresh catalyst is sub-stantially completed, a relatively large amount of a regenerating gas, preferably air, is admixed with the catalyst mixture, and some coke oxidation occurs.  The balance of coke oxidation takes place in a downstream-situated regeneration zone of substantially conventional design.  The regenerating gas addition is preferably made at the base of a cone-shaped combustor in order to provide venturi effect which ensures good air-catalyst mixing.

Abstract: ABSTRACT OF THE DISCLOSURE ___ ._ _ Apparatus includes means that both advance wedge material stock and also substantially permanently form the stock material to precise dimensional tolerances; means by which the formed material is retained in the formed configuration thereof; wedge severing means; and means for loading severed wedges into a wedge magazine. The wedge magazine comprises the lower tooling of a  coil injection machine and forms, in effect, an extension of tool gaps that accommodate winding coils in a coil injection machine.          The magazine receiving the wedges may be a short term storage magazine which in turn feeds the wedges to a wedge magazine that forms the lower tooling of a coil injection machine.  The multifunction machines that perform the multiple function of: making wedges for stator cores, inserting coils of winding turns into stator cores, and placing the wedges in at least selected slots of a stator core.    The means for advancing wedge material stock and also substantially permanently forming the stock material includes a pair of pinch wheels or rollers that pinch the stock therebetween to feed wedge material.  One of the wheels is driven through a clutch-brake system arranged so that it may be driven unidirectionally only from a re-ciprocating drive arm.  The other wheel is supported so that it may be selectively urged toward the first wheel in order to pinch and feed wedge stock material.  The wheels or rollers are contoured and dimensioned 50 that wedge material being rolled therebetween will be formed into a desired configuration.  The forming of precisely controlled dim-ensional tolerances and dimensional stability, with the result that the wedges lie squarely in stator core slots (when the wedges are inserted into such slots), and "wire over wedge" problems associated with skewed wedges in stator core slots are overcome.

Abstract: Abstract A hydrocarbon conversion-catalyst regeneration process and apparatus is described for converting residual oils and regeneration of catalyst in two separate low and higher temperature regeneration stages stacked one above the other on the same or different vertical axis to provide catalyst at a temperature above the residual feed psuedo-critical temperature.  A CO rich flue gas is recovered from the low temperature regeneration stage and a CO2 rich flue gas is recoveredfrom the higher temperature regeneration stage.  The temperature of the catalystmixed with the residual oil feed is sufficient to obtain substantially complete vaporization of the residual oil charge.  A special arrangement of apparatus is provided in the lower portion of a riser conversion zone to obtain the intimate vaporization contact between residual oil feed and the high temperature catalystcharged to the riser.
