Abstract: A corner vent for windshields having rearwardly extending panels utilizes a hollow corner post having a concave inner surface with one or more adjustable ventilators therethrough and communicating with the interior of the post. A vent door is formed in an outer convex surface of the post and hingedly attached adjacent a rearward edge of the post. A lever attached to an inside surface of the vent door extends through the inner surface of the post to open and close the vent door. In the closed position, the post gives the appearance of a solid post, and in the open position, air flow is directed into the interior and through the ventilator. The corner vent is applicable to power boats and the like.

Abstract: A holder for SCUBA tanks or other similar cylindrical articles for storing such tanks along the deck of a boat or the like is molded from a unitary sheet having at least one concavity extending from the upper surface interiorly between the lateral sides, the sheet being sufficiently flexible that the weight of a SCUBA tank stored within the concavity causes flexure of the sheet so that the concavity rests on the supporting surface.

Abstract: The present invention relates to a filter for liquids. More particularly it is concerned with providing a clog-resistant filter of the kind in which a filter element (usually of hollow cylindrical shape), having at least one open end and with walls of metal, plastic or other suitable material bearing numerous perforations, is placed within a housing in such a manner that the liquid entering the housing must flow from the inside of the filter element out through the perforations in the latter, before it can leave the housing, with the result that solid material strained from the liquid flowing through the filter is retained within the filter element.

Abstract: A surgical method and apparatus for opening and closing surgical wound utilizes an elastic member which is adhered across the patient's skin at the treatment site. The wound is opened by cutting through the elastic member and through the patient's skin to permit a surgical procedure to be conducted. The wound is then closed by reapproximating the patient's skin at the treatment site and by bringing the cut edges of the elastic member together and adhering a relatively inelastic sealing member over the elastic member to maintain the cut edges while the wound heals.

Abstract: A miniature irrigation water spray fitting includes a body part having a top and a bottom and with an inlet for receiving longitudinal flow of water from the bottom. The body part also includes a depending skirt between the top and the bottom extending generally radial to the flow of water through the inlet. The cap part is threaded onto the top of the body part and has a depending edge engaging the skirt of the body part when the cap part is screwed fully home, the cap part having an outer peripheral gripping edge. One of the body or cap parts has plural radial grooves extending along the respective skirt or depending edge to permit the radial flow of water from the fitting. The cap part gripping edge permits a field worker to quickly clear any clogging of the grooves by rotating the cap part a half turn or so, and thereafter quickly rotating the cap part fully home again.

Abstract: A buoyant module which is useful in the construction of modular docks, marinas and the like is fabricated by providing a buoyant member and applying a protective sheet over a portion of the member, and pumping a fiber-reinforced concrete layer over one face of the buoyant member. Structural rods extending through the layer are interconnected with peripheral whalers, which in turn permit the buoyant member--concrete layer combination to be joined together with similar modules in a unitary, low cost and facile construction.

Abstract: A plurality of shucked scallops are mechanically eviscerated utilizing a series of longitudinally aligned inclined channels, each channel formed of a bottom roller and adjacent side rollers, the side rollers extending generally parallel with and longitudinally coextensive with the bottom roller. The frictional surfaces of the rollers and the spacing between adjacent rollers, or both, are controlled to effectively separate the soft scallop viscerae from the soft adductor muscle of the scallops without significant damage to the muscles, that in such a manner as to be ineffective for the peeling of shrimp.

Abstract: An integrated pesticide applicating system utilizes lengths of small diameter closed end flexible tubing with periodically spaced perforations having open ends terminating at junction boxes which are serviced on a periodic basis by certified pest control technicians utilizing expanding chemicals that are administered in measured quantities to provide a residual pest control block in concealed areas of a building. Externally mounted junction boxes provide a pest control method in which the chemicals can be applied without the necessity of access to the interior of the building by the servicing technician. Tubing perforations are preferably conically shaped.

Abstract: An improved protective device for the arm of a person receiving blows from a participant in martial arts activities or the like. The device includes a main body portion formed of a resilient, conformable material such as a closed cell polyvinyl chloride foam and a pliable coating of polyvinyl chloride or the like. The main body portion has an enlarged main section, an outwardly extending hand section and an inwardly extending elbow section. The hand and elbow sections are circumferentially displaced with respect to each other. Straps secure the main body portion to the arm of a wearer. Hand pieces secure opposite edges of the device at the hand portion for being gripped by the wearer and to assist in correct placement.

Abstract: A water purifying system having a condenser made of two superposed sheets of hydrophobic plastic film bonded together to form a tortuous steam path through the condenser. As steam enters the condenser it is cooled by the ambient air, condensed into water and then removed from the condenser.

Abstract: An improved optical assembly which provides a panoramic field of view for infrared motion detection. In one form of the invention the optical assembly comprises a spherical section having an inner surface and an outer spherical surface, the outer spherical surface having a radius of curvature centered in a focal region which is suitable for placement of an infrared detector. The inner surface of the spherical section comprises a plurality of circular convex lenses, each lens having an optical axis passing through the focal region. The combination of the outer spherical surface with each circular convex lens forms a biconvex lens having a focal point in the focal region. Radiation received by each biconvex lens from a zone in the field of view is focused in the focal region for sensing by the infrared detector.

Abstract: A method for protecting whole citrus fruit or vegetables from chilling injury comprises the step of treating the skin of the fruit or vegetable with a medium containing squalene or a squalene-derivative.

Abstract: A system and method for treating "septage" (i.e., wastewater collected from septic tanks and similar installations) utilizes a reactor tank for treating the anaerobic wastewater with an oxygen-containing fluid so as to substantially increase the dissolved oxygen content and thereby render the wastewater aerobic and suitable for input into a municipal wastewater treatment facility. Volatile gases are drawn off from all of the reactor tanks and placed into a treatment tank for a reduction of the bacterial and odor levels by reaction with a chlorine-containing water output of the municipal wastewater treatment facility.

Abstract: A marine engine exhaust system and method utilizes first and second enclosed, generally tubular chambers having generally parallel lengthwise dimensions and internal intermediate exhaust passageways spaced along the lengthwise dimension of the second chamber for circulating the exhaust gases through the first chamber, laterally through the intermediate exhaust passageways into the second chamber, along the lengthwise dimension of the second chamber and then out of an outlet exhaust passageway which passes through the second chamber wall and may also extend through a cooling water-collecting portion of the first chamber to achieve maximum muffling of the exhaust gas noise.
