  • Patent number: 4500492
    Abstract: An apparatus (21) and method is disclosed for keeping interior walls (28) of a reaction vessel (22) free of undesirable deposits of solid materials in gas-to-solid reactions. The apparatus (21) includes a movable cleaning head (36) which is configured to be substantially complementary to the interior contour of the walls (28) of the reaction vessel (22) and which is disposed in close proximity to the walls (28). The head (36) ejects a stream of gas with a relatively high velocity into a narrow space between the head (36) and the walls (28), and in accordance with Bernoulli's principle the head (36) is biased towards the walls (28) by the pressure prevailing in the reaction vessel (22). The gas ejected from the head (36) is of such composition that it does not participate significantly in the chemical reaction conducted in the reaction vessel (22).

  • Patent number: 4491565
    Abstract: A liquid-liquid contacting apparatus is disclosed. The apparatus is useful in extracting mercaptans from a hydrocarbon stream such as cracked gasoline by nonturbulent countercurrent contacting of the hydrocarbon stream with an aqueous caustic solution. The denser liquid phase flows downward from an upper phase separation zone through a connecting cylindrical contacting zone into a lower phase separation zone. Liquid withdrawal and addition means communicate with each separation zone. A mass of fibrous contacting strands is suspended in the contacting zone. The contacting strands are preferentially wetted by either of the two liquid phases to provide a large surface area which enhances extraction capacity.

  • Patent number: 4389217
    Abstract: A recording device is described, useful as an integrated time-temperature or radiation-dosage history indicator. The device contains a substrate having deposited thereon at least two indicating units, one being unreacted and representing zero time of exposure and the other unit being pre-reacted. Each unit is comprised of an acetylenic compound containing at least one --C.tbd.C--C.tbd.C-- group, capable of reacting by 1,4-addition polymerization thereby forming an end-point color after an irreversible, progressive color change upon thermal annealing or exposure to actinic radiation. The end-point color represents an integrated time-temperature history of thermal annealing or radiation-dosage history. Each unit is constructed such that the time required to form the end-point color by thermal annealing at a given temperature or for a known thermal history, or exposure to actinic radiation at a given average radiation dosage rate, is predetermined.

  • Patent number: 4332775
    Abstract: Hydrogen is produced by dissociation of water in a rotary tubular reactor (1) having a receiving end covered by a cap (2) transparent to solar radiation and provided with a small window (12) connecting a collecting chamber (3) to an opaque insulated heating chamber (5).The tubular reactor (1) constitutes a "black chamber" provided with two series of tubes (7, 8) for heating and dissociating the water. Tubes (7) have a porous section (7a) for separating hydrogen by molecular diffusion according to Knudsen's principle.The concentrated solar radiation entering through the small window (12) falls on one end of the tubes (7, 8) and is largely absorbed by multiple reflections on these tubes.A slow rotation of the reactor (1) enables the bending forces and stresses due to the weight to be compensated.

  • Patent number: 4331633
    Abstract: A batch sterilizing unit, in the form of a tank having a top loading port and a bottom discharge port, holds a batch of cans for sterilization. The cans in contact with the door associated with the discharge port are prevented from transferring heat to the door and accordingly are maintained at sterilizing temperature by providing a perforated partition forming a wall of condensate sump. Thus the sterilizing medium, whether it be steam or water, is able to effect complete sterilization of those cans making contact with the partition. In addition, condensate is continually discharged from the unit, when steam is the sterilizing medium, insuring creation and maintenance of sterilizing temperatures to the cans resting on the discharge port door.
