Abstract: An immunological test kit suitable for the rapid detection of ciguatoxin and related low molecular weight lipid polyether marine toxins in fish tissues in the field, home or laboratory. The test procedure utilizes a synthetic membrane laminated onto one end of a solid plastic stick, which is immersed into alcohol with a piece of fish tissue. The membrane is then removed and dried thoroughly, then placed in the suspension of mixed colored beads coated with anti-ciguatoxin. The membrane is then rinsed in water and the intensity of the color compared with a standard range of colors formed (0-3+). The color intensity is proportional to the concentration of toxin in the piece of tissue. The kit includes the synthetic membrane on a plastic stick, a suspension of mixed colored beads coated with anti-ciguatoxin antibody, testing instruments, and a supply of solvent.

Abstract: Ballast water is treated by applying ultrasonic frequencies to the water to kill organisms entrained in the water such as diatoms, veligers, fish larvae, plankton, and microorganisms, preventing the introduction of non-indigenous species between ports-of-call. The ballast water is circulated through a ballast treatment system. A pump is connected to a tube lined with a piezoelectric material for aiding in transmitting the ultrasonic frequencies connected to one or more ballast tanks of a ship. The use of the piezoelectric material as a lining allows a broad range of sound wavelengths and energy levels to be transmitted greater distances before problems with uniform sound penetration and energy loss within the sound field occur. Additionally, spatially-controllable, continuous constructive interference zones may be generated within the piezoelectric-lined tubes to specifically target the particular organisms entrained within the ballast water being treated.

Abstract: A lysimeter has an elongated, relatively narrow sample pipe with flanges at upper and lower ends. A lysimeter assembly is connected to the lower end of the sample pipe by connecting an upper end of a central tube in the assembly to a lower end of the sample pipe. A circular lysimeter pan extends around the central tube. Vertical slits in the central tube provide a screen to permit water flow into the central tube from the pan but to prevent granular materials from the filter pack. Vertical webs in the pan rigidify the pan, and radial supporting webs and a ring beneath the pan support the pan. A relatively large diameter collection chamber has a spheroidal lower end and an upper end which receives the ring for centering the lysimeter pan at the upper end of the collection chamber. An outward and upward sloping flange at an upper end of the collection chamber with an elastic seal supports the lower conical wall of the lysimeter pan.

Abstract: A camping trailer is provided having a configuration to cooperatively combine with a towing automobile to integrate interior compartments and spaces of each into usable space. The trailer has a wheeled chassis provided with a forwardly extending tongue assembly and hitch assembly for interconnecting with the towing automobile and carrying a body structure having a front end portion configured to detachably interconnect with the rear end of the automobile. The front end portion has a front wall surface inclined upwardly in a forward direction to complement an opposed rear wall surface of the towing automobile and is provided with a flexible bellows that is detachably secured to the towing automobile around a rear hatch-type door of the automobile. An opening in the front wall surface of the trailer body structure permits opening of the rear hatch door of the automobile by swinging movement of the door through the opening and into the interior of the trailer thereby enabling combined use of the interior spaces.

Abstract: A protective cover is provided for a golf bag with this cover including a dual compartment interior construction. The cover comprises a shell-form body fabricated from a pliable sheet material and dimensionally configured to cooperatively interfit the open, tip-end of a golf bag. Constructed in the interior of the shell-form body which is of elongated tubular shape having a closed end, is a longitudinally extending partition wall which divides the interior into two compartments for receiving the irons and the woods, respectively. A resilient securing cord is provided which extends around the shell-form body and has attachment hooks secured to each end for engaging belt loops or attachment rings fastened to the upper peripheral edge or end of the golf bag. The resilient cord extends across the body in a transverse manner at the juncture of the partition wall to cooperate therewith in maintaining the irons and woods in segregated pockets, particularly if the golf bag should be inadvertently inverted.
