Abstract: A process and reactor apparatus are disclosed for upgrading paraffinic feedstocks to olefinic and/or aromatic products. Hydrogen diffuses through a selectively permeable membrane from the reaction zone into a combustion zone where it reacts exothermically with an oxygen-containing fluid to supply at least a portion of the endothermic heat of reaction for the paraffin upgrading process. Additionally, in-situ separation of by-product hydrogen from the reactant mixture in the reaction zone increases yield of valuable olefinic and aromatic products.

Abstract: The element is disposed in a vessel receiving a fluid flow. The vessel wall is porous at least for a proportion of the fluid and bounds an inner chamber communicating through the vessel wall with a chamber outside the vessel. The element is in the shape of a plate or tube and is so devised that the porous wall either on its own or in combination with other similarly shaped elements to form a module, forms a turbulence generator particularly in the form of a static mixer for the fluid flow. The resulting turbulence on the wall of the elements ensures that the wall remains porous.

Abstract: A device for the automatic addition of a corrosion inhibitor to a cooling system, such as in an automobile engine, utilizing osmotic pressure. The device includes a container for a concentrated corrosion inhibitor solution with a semi-permeable osmotic membrane in contact with and separating the inhibitor solution from the coolant in the overflow reservoir. With properly inhibited coolant, the osmotic pressures balance, but if the level of inhibitor in the coolant drops, water passes through the membrane to force inhibitor solution through an overflow tube or opening to mix with the coolant and raise the inhibitor level therein to a predetermined value.

Abstract: An improvement in self-driven miniature fluid dispensers is disclosed. The basic components of the dispensers are: an outer rigid semipermeable cellulose membrane that acts as a housing, an inner collapsible bag housed within the membrane that is adapted to contain the fluid, a water-imbibing composition interposed between the outer membrane and the inner bag, and a port that extends from the interior of the bag to the exterior of the dispenser through which the fluid may be charged to and discharged from the dispenser. The improvement lies in using a blend of cellulose acetate butyrate and polymethylmethacrylate to make the outer membrane, thereby forming a membrane of reduced water permeability.

Abstract: An osmotic device for delivering an active agent is disclosed. The device is comprised of a wall surrounding a compartment and has a passageway through the wall for dispensing the agent. The wall is formed of a material permeable to an external fluid and substantially impermeable to agent and a gas generating means. The compartment is comprised of an active agent and a gas generating means that either exhibits an osmotic pressure gradient against the external fluid, or the means is mixed with an osmotically effective compound that exhibits an osmotic pressure gradient against the fluid. Agent is released by fluid being imbibed through the wall into the compartment at a rate controlled by the permeability of the wall and the osmotic pressure gradient across the wall, which fluid wets the means causing it to react and produce an effervescent solution containing agent that is dispensed under pressure through the passageway to the exterior of the device.

Abstract: A wall surrounding and forming a compartment for containing a useful composition of matter and having a passageway for dispensing the composition is disclosed. The wall is comprised in at least a part of a material permeable to an external fluid. The composition is soluble in the fluid and exhibits an osmotic pressure gradient against the fluid or the composition has limited solubility and is admixed with an osmotically effective compound soluble in the fluid that exhibits an osmotic pressure gradient against the fluid. In operation, composition is dispensed from the device by fluid permeating into the compartment producing a solution of the soluble composition or a solution of the osmotically effective compound containing the composition, which solution in either operation is released through the passageway to the exterior of the device at a rate controlled by the permeability of the wall and the osmotic pressure gradient across the wall of the device.
