  • Patent number: 4394332

  • Patent number: 4364446
    Abstract: Methods and devices are disclosed for generating acoustic pulses in a water or land medium, e.g., for use in seismic investigations. The pulse amplitudes, waveshapes, and frequencies can be controlled by signals that may originate at a remote location. Compressed gas is confined at high pressure in a valve chamber (12, 194). An initiating signal causes the opening of a passage (54, 56, 192) from the chamber into the medium to initiate the rise of a pressure pulse therein. A second signal causes the closing of the passage in a manner such that the initial rise of the pressure pulse is limited by the closure of the passage. In one device, the passage is opened by one sleeve valve member (60) and closed by another sleeve valve member (58). In another device the passage is opened by a sleeve valve member (196) whose motion to open the passage is arrested substantially instantaneously by transferring its momentum to a momentum exchange sleeve (246) that is then gradually decelerated.

  • Patent number: 4322394
    Abstract: Dielectric heating with microwaves of saturated solid noncarbon adsorbents to remove the adsorbed materials results in more rapid, efficient and safe regeneration than conventional heating. The microwaves heat the adsorbents internally and in the absence of spark discharges without thermal and mechanical degradation of the adsorbent, and also in the absence of activating gas bring the adsorbents to a temperature sufficient to desorb the adsorbate. Separation of a gas mixture into two concentrated streams of its components is enabled by adsorption of one fraction by a selective adsorbent followed by removal of that fraction with dielectric heating and little or no purge gas. Useful by-products of the separation process are thereby economically recovered.

  • Patent number: 4105014
    Abstract: Acid and base catalyst substances are employed in the photochemical process for collection and retrieval of solar energy wherein a lower energy level isomer (e.g. trans-isomer) of a photochemical isomerizable compound is exposed to solar energy of a wavelength providing a higher energy level isomer (e.g. cis-isomer) of this isomerizable compound and this higher energy level isomer subsequently is transformed to its lower energy level isomer with exothermic release of thermal energy for useful purposes. In this process the transforming or conversion of the higher energy level isomer to its lower energy level isomer is facilitated by the presence of and/or contacting with the acid or base catalyst substance.

  • Patent number: 4004573
    Abstract: For collection, retrieval, and utilization of solar energy, there is taught a process and an apparatus wherein a photochemical fluid, containing an isomerizable compound, is passed through a collector for exposure to solar radiation to transform the isomerizable compound to a higher energy level isomer. The irradiated fluid leaving the collector passes in heat exchange relationship with photochemical fluid entering the collector and then proceeds into a trigger reactor means. In the trigger reactor means, higher energy level isomer in the irradiated fluid is triggered, such as by heat and/or catalyst contact, to revert to an isomerizable composition of a lower energy level isomer with exothermic release of heat in excess of that requisite for maintaining conversion of higher energy level isomer to lower energy level isomer.
