Abstract: A controlled release composition for use with liquid acids, and a method of preparation is disclosed. The composition comprises (1) a porous matrix comprising and substantially inert to an absorbed acid; (2) a midlayer surrounding the matrix, this midlayer consisting essentially of a salt of the absorbed acid; and (3) a membrane surrounding the matrix, the membrane being exterior of the midlayer, the membrane further being substantially inert to the midlayer and permeable to a selected environment, the thickness and permeability of the membrane comprising means for controlling diffusion of the environment therethrough.The midlayer can be applied as a coating to the acid-bearing matrix, or it can be evolved by exposing the acid-bearing matrix to a base such as ammonia gas or a solid metal oxide for a time sufficient to allow reaction of a proportion of the acid at or near the surface of the matrix with the base to form a layer of the corresponding salt.

Abstract: Catalytic chemical and biochemical conversion reactions are carried out in a novel compartmentalized catalytic reactor which enables the energy-efficient coupling of the conversion reaction with various energy-consuming post-conversion operations. The catalytic reactor is compartmentalized by means of a multilayer composite membrane comprising a catalytic membrane layer and one or more permselective membrane layers. The arrangement and properties of the membrane layers are such as to enable the free energy change of the conversion reaction to be utilized as the required energy source for effecting various post-conversion operations, including product separation, recovery and enrichment, and second-stage catalytic conversions with unfavorable reaction equilibria.

Abstract: The contact area between a first phase of a multi-phase system and a liquid second phase of the system is increased by effecting transient electrical discharges between electrodes immersed in the liquid second phase or in a volume of liquid in acoustic communication with the liquid second phase. The first phase can be in the form of a particulate solid, a gas, or a liquid of lower density than that of the second phase. The first phase is mingled with the second phase by a bubbling technique where the first phase has a lower density than the second phase. The hydraulic shock waves produced by the electrical discharges disperse the bubbles or particles of the first phase in the liquid second phase and thus increase the contact area between the phases.When the electrodes are immersed in a volume of liquid separate from but in acoustic communication with said liquid second phase, these liquids are separated by means of an acoustically transmissive membrane formed from a thin film of stainless steel or from rubber selected such that the product of density (.rho.) and velocity of propagation of sound waves (c) is matched to those of the liquids separated by the membrane.The spacing between the electrodes is adjusted in response to a sensed parameter of the electrical discharges such as to maintain the sensed parameter constant.

Abstract: An osmotic active agent dispenser is comprised of a chamber having controlled permeability to an external fluid, i.e., water, and containing an osmotically effective solute which, in solution, exhibits an osmotic pressure gradient against said external fluid, said chamber housing a flexible bag of relatively impervious material containing an active agent and provided with means or dispensing head for releasing said active agent to the exterior of the dispenser. The flexible bag is disposed within the said housing chamber such that as the, e.g., water permeates from the external environment through the permeable walls of the chamber and migrates or diffuses by osmosis into the solution contained therein, same increases in volume thereby generating mechanical compressing or deflating force on the flexible bag, which force in turn ejects the active agent out of the apparatus at an osmotically controlled rate over a prolonged period of time.
