Abstract: A portable advertisement display utilizing a plurality of lightweight panels pivotally interconnected by hinges. The panels themselves are constructed of a polystyrene core located intermediate two rigid pressboard panels. Such material is very lightweight but will not accommodate direct connection of hinges. A channel member is secured to selected lateral edges of each panel to provide a stable base on which to connect the hinges. Each panel is sheathed in fabric characteristic of the looped facing of hook-and-loop adhesive material. The panels may be detachably connected in vertical orientation of one another by magnetic strips located on the upper and lower marginal edge of each panel. Advertisement items such as signs or placards are attached to the present invention with strips of fabric characteristic of the hooked portion of hook-and-loop adhesive material.

Abstract: An instrument to be used during ocular surgery for the rapid closure of anterior segment openings and the control of expulsive choroidal hemorrhage and the resulting damage caused by this complication. The instrument is to be positioned over the anterior ocular surface of the eye at the first indication of hemorrhage or "posterior pressure". One or more dimples located on the upper surface of the instrument allows the insertion of a elongated member for holding the instrument in place while maintaining the intraocular pressure. An opening is also present which allows a surgeon to insert sutures into the underlying eye while the instrument is in place and also aids in the movement of the instrument about the anterior ocular surface of the eye by insertion of a probe or forceps. The instrument is transparent, allowing the surgeon to visually monitor the intraocular events.

Abstract: A sit and climb tree stand uses a wedging tree engagement bar to provide for positive support in the tree with minimal tree damage. A self-locking leveling feature is provided which allows the user to adjust the level when at the desired elevation.

Abstract: An automatic, lockable, and releasable range-taking cable connection for use in pole line application utilizes a pair of spring loaded gripper elements movable on inclined planar surfaces within a housing, with the gripper elements connected to a retractor mechanism that translates rotational motion of a retractor into axial movement of the grippers to release the same from the cable. A rotatable locking sleeve or cap is used to secure the gripper elements in locked position when in normal use.

Abstract: A continuous air monitoring apparatus utilizes a solid sorbent preconcentrator to concentrate airborne sorbent compounds for gas chromatographic analysis. Direct connection between the preconcentrator and gas chromatographic column allows direct desorption of the compounds into the column with minimal dead space. Temperature control on the column allows sharp chromatographic peaks to be attained without cryogenic focussing.

Abstract: A card rack for receiving, storing and organizing cards or other articles or general planar definition including a plurality of interconnected plates supported in vertical alignment within a frame. The plates extend diagonally within the frame forming a plurality of slots. The plates are interconnected by engagement of an insertion bar formed on each plate within a receiving channel formed on each adjacent plate.

Abstract: A method by which a mucoprotectant gelatin which forms a protective coating on the mucous membranes of the mouth is provided for use with active ingredients for treating the teeth. The active ingredient may be an aqueous hydrogen peroxide solution or fluoride. When hydrogen peroxide is used as a bleaching agent the mucoprotectant prevents the caustic bleaching agent from damaging the gums. The bleaching agent and the mucoprotectant are stored in separate containers and are custom mixed by a supervising dentist and given to the patient in a dispenser so that the resulting slurry may be used in a personalized vacuformed mouthpiece. The treatment may last from several minutes to several hours.

Abstract: A mobile cervical brace for support, immobilization, and extension of the cervical vertebrae utilizing a base portion, a cranial support member selectively movable by an extension component relative to the base of the brace. Movement of the cranial support member is accomplished by a worm screw which engages and disengages threaded slots of a depending guide of the extensions means affixed to cranial support member to move the cranial support member relative to the base of my brace.

Abstract: A flip-type display sign having a plurality of parallel louvers mounted in a frame utilizes flexible fabric louver covers to define the faces of the louvers, with the louver covers being supported on a plurality of cables, extending between a pair of end caps held in spaced relation by a lightweight tubular frame. The fabric covers may be independently removed or replaced or may be internally illuminated.

Abstract: A bed cleaner for dump trucks utilizing a scraping carriage located in the bed of a dump truck and operated by cables connected to a winch assembly to dislodge and remove adhering materials from the dump bed while the dump bed is in an inclined position. The apparatus includes a device for remotely or automatically controlling the movement of the sliding carriage on the dump bed.

Abstract: A dead front fuse mounting assembly for use in high voltage enclosures, utilizes a shock absorber assisted door design to reduce impact forces which occur when such assemblies are improperly opened. Secondly the interior of the fuse compartment is closed to entry by foreign objects by an insulating door which moves concomitantly with the fuse mounting assembly and is locked in a closed position when the assembly is in its open position.

Abstract: A condensate control apparatus for receiving drum type condenser units utilized in cotton ginning which eliminates moisture buildup on predetermined metal surfaces within the condenser unit by heating such surfaces with heated dry air emanating from a heat source and conducted to such surfaces through a series of heating ducts. The condensate control apparatus also compacts the cotton gin fiber collected by such condensers into batts wherein the compacting force utilized in combination with moisturized air integrated within the cotton is sufficient to overcome the cottons inherent resiliency thereby permanently reducing the volume per unit weight of such cotton batts.

Abstract: An improved kingpin includes a shaft pivotally secured within a bearing and mounted within a trailer, the kingpin being positioned in downward extension therefrom for secured engagement within a conventional fifth-wheel. Also included are couplers for automatically connecting a tractor's service lines to the trailer concurrent with the engagement of said kingpin within said fifth-wheel.

Abstract: A tree stand having a weight bearing platform and a gripping frame hingedly joined thereto utilizes a pair of variable length suspension braces connecting the outer end of the platform to the gripping frame. By varying the length of the braces the platform is leveled while positioned on the tree. The hinged construction also allows for easy folding of the stand for storage and transportation.

Abstract: A new variety of Wax Myrtle distinguished by its deeply serrated leaf pattern and its resistance to leaf spot disease as well as the characteristic wax myrtle fragrance when crushed.
