Abstract: A process and apparatus for achieving turbulent or fast fluidized bed regeneration of spent FCC catalyst in a bubbling bed regenerator having a stripper mounted over the regenerator and a stripped catalyst standpipe within the regenerator. A coke combustor vessel, which may be partially or totally open to the dilute phase above the bubbling bed, is added to the existing regenerator vessel. Spent catalyst is discharged into the coke combustor, regenerated in a turbulent or fast fluidized bed, then discharged into the dilute phase region above the bubbling bed, either via a deflector or by simply overflowing the combustor. Regeneration of catalyst is completed in the bubbling dense bed, and/or an annular fast fluidized bed surrounding the coke combustor. Catalyst may be recycled from the dense bed to the coke combustor either by a flow line, or by adjusting relative heights of bubbling to fast fluidized bed.

Abstract: A self-contained, programmable temperature sensor is positioned within a suitable pressure housing affixed to a borehole tool to record and store temperature data at predetermined times during operations of the borehole tool in a borehole penetrating a subsurface formation. The depth of the temperature sensor within the borehole corresponding to each temperature reading is recorded. After the borehole tool is removed from the borehole, the temperature sensor is removed from the pressure housing and the stored temperature data is retrieved for use in producing a record of borehole temperature versus depth within the borehole at the programmed times.

Abstract: An adhesively laminated composite plastic film comprising at least two layers of preformed plastic film adhered together by means of an adhesive material disposed therebetween but having preselected areas which contain neither the adhesive nor anything else which is incompatible with said plastic is disposed between the layers of plastic film or on the surfaces thereof. The composite is quite usable for forming into plastic bags by either folding the composite film upon itself and heat sealing the meeting edges, or by superposing the composite film with at least one other plastic film, which may itself be a composite film, and then heat sealing the meeting edges. The preselected areas which are devoid of adhesive correspond to the heat seal areas.
