Abstract: An optically pumped crystalline laser that includes a small single crystal section of a polygonal cylinder; the dimensions of the crystal section and the index of refraction of the crystal and the medium surrounding the crystal are such that there is formed a dielectric resonator that is totally reflective for a small number of modes. The material of which the crystal section is composed is one that is capable of being made optically thick in thin sections. The resonator is optically pumped and the lasing radiation therein is coupled to an optical element that is placed in close proximity thereto by virtue of an evanescent field that arises from the lasing action in the resonator.

Abstract: An apparatus for eviscerating a marine animal of the mollusk type, such as a squid, wherein the head region of the squid is appropriately held and a gradually increasing pressure is applied to the body thereof as the head and body are relatively moved in opposite directions from each other, whereby the head and attached viscera are readily and cleanly removed from the body. The marine animals are held to the conveyor during the time of removal of the head and viscera by power driven pressure rollers. The power driven rollers advance the marine animals in the direction of movement of the conveyor.

Abstract: A three-phase high-voltage superconducting cable having three hollow superconductors in a trefoil configuration and three heat shields disposed radially outward from the superconductors, all enclosed in an evacuated pipe. The heat shields are also in a trefoil configuration; they are electrically isolated from one another, from the superconductors, and from ground in order to suppress the flow of induced currents. The pipe provides mechanical protection of the foregoing elements, serves as vacuum vessel and carries the a-c shielding current induced by the cable load current.

Abstract: A method of altering (i.e., deactivating or activating) the biological activity of macromolecular species that employs laser beam radiation at a frequency that excites vibrational and rotational states of the irradiated species and at an intensity sufficient to activate the species (but below the denaturation level) or to a level such that the weak bonds-- e.g., hydrogen bonds--that determine the spatial character, and hence the biological activity of macromolecules are irreversibly broken to such extent that the macromolecule loses its original form (the process of denaturation) and assumes an inactive (denatured) configuration. The latter is a sterilization or inactivating process and for such sterilization the macromolecular species may be disposed on a highly reflecting surface, such as a metal, which reflects the beam and is capable of amplifying the destructive characteristic, or upon absorbing surfaces, such as plastics, cloth or paper which ordinarily would be destroyed by the beam.

Abstract: A multi-node network having two sets of SCRS, each set comprising a pair of parallel-connected, oppositely-polarized SCRs, the sets being electrically joined to form a common connection whereby electric current can flow through one pair to the common connection, thence to a load and/or to and through the other pair, or electric current can flow through said other pair to the load. Each SCR of the SCR pairs is triggered by transient signals such that the common connection can receive continuous power through either set of SCRs of the power and the connection can be switched between sources.

Abstract: An optical torquemeter adapted to provide torque readings as accurate as 1-to-2 foot pounds over a torque range of the order of 1 to 2 thousand foot pounds. It converts a binary-type optical message to an electric signal in the form of variable-width pulses. The width of the electric pulses indicates both the magnitude and the direction of torque and the pulses are processed to provide an output representing torque.

Abstract: This invention relates to a new, biologically active material conforming to the formula ##SPC1##The material is formed by a process comprising displacement of the thiazolidine ring in Pencillin V and formation of the cephem system.

Abstract: A multiport diffuser for discharging condenser cooling water from thermal power plants and the like, the diffuser being adapted for installation at the bottom of a large body of water and being operable to discharge the condenser cooling water at that submerged location. The diffuser consists of a main pipe disposed along the bottom of the large body of water and a large number of nozzles oriented at predetermined variable angles to the axis of the main pipe, the angle of orientation being a function of the distance of a particular nozzle away from the longitudinal center of the main pipe and also a function of the half-length of the main pipe.

Abstract: A recording instrument for use in ocean depths and like remote locations and adapted to provide meaningful readings of temperatures and pressure, for example, at such locations over a long period of time without attendance. Analog signals from transducers, which indicate the level of the thing-to-be-measured, are processed to give an averaged digital signal that is then stored on a magnetic tape. The system is battery powered. The instrument detailed is for use at ocean depths where the instrument housing and attachment to a mooring line are of particular importance.

Abstract: A process wherein a solution is allowed to fall from the end of a capillary tube in the presence of a gradient field of an applied force field (magnetic or electric). If the fluid contains ions that are susceptible to the applied field, then the content of those ions can be correlated to the change in the specific characteristics of the capillary drop (i.e., the drop weight or equivalently the drop volume). This finds use as an assay technique for those susceptible ions, and it further can be used to give information as to the degree of susceptibility that the ions show to the applied force field.

Abstract: A process for preparing cathodochromic materials whereby coloration properties of the materials are enhanced by a low-temperature re-crystallization process. Crystalline powders formed using either hydrothermal or sintering growth techniques are hydrothermally re-crystallized at a temperature sufficiently high and for a time sufficiently long to effect re-crystallization. The temperature range for hydrothermal re-crystallization is 60.degree.C to 300.degree.C and the re-crystallization growth time is at least the order of 12 hours and, more typically, the order of three days. There is shown a cathode ray tube employing said materials.
