Abstract: The inventive applicator has a pliable plastic tube for holding a hermetically sealed crushable glass ampoule containing fluid to be dispensed from the applicator and applied by the applicator to a surface, and a pliable dispensing member mounted onto the plastic tube. The dispensing member has a dauber from which the fluid is dispensed and a protective device which surrounds a portion of the tube and is squeezed inwardly between the user's forefinger and thumb to cause the portion of the tube positioned thereunder to deform inwardly and crush the crushable glass ampoule positioned within the tube to release the fluid contained within the ampoule. The protective device guards against and minimizes the chances of users being cut by glass shards of the crushed glass ampoule when the protective device is subsequently squeezed inwardly to cause the fluid to move through the applicator to the dauber.

Abstract: A single use applicator for dispensing and applying a thin layer of viscous fluid, comprising an outer body of chemically inert deformable material open at one end, a crushable glass ampoule therein containing fluid to be dispensed and applied, and an application element of synthetic fiber strands in said tube, wherein fluids flows by capillary action, with an internal reservoir inside the tube adjacent the ampoule, a fluid control valve welded to the tube at its approximate mid point, to control fluid flow, and an external tip to apply the fluid to an application surface.

Abstract: Methods and apparatus are provided for indicating safe or potentially hazardous operating conditions of an aircraft in a required navigational performance (RNP) environment. The apparatus comprises a course deviation display field with first and second markers defining outer boundaries of the RNP width and a central marker indicating the desired course within the RNP width, an aircraft estimated position uncertainty (EPU) marker in the display field whose size corresponds to the EPU relative to the RNP and a current aircraft position marker coupled to the EPU marker and moving therewith as the aircraft position changes with respect to the RNP width. The display desirably changes color and/or flashes to alert a pilot to a potentially hazardous condition when an outer boundary of the EPU marker approaches to within a predetermined guard-band distance of or overlaps either of the first or second markers. An audible warning can be included.

Abstract: In an aircraft flight instrument display system having a display screen for displaying flight information, an airspeed indicator is displayed in a vertical tape format, and has a low speed range indicator with a low speed range identified on the airspeed indicator by highlighting the low speed range, and has at least a settable indicator within the low speed range indicating a critical airspeed. The low speed range indicator and the critical airspeed indicator are both set with only manual inputs.

Abstract: An applicator for dispensing liquids including an outer tube (11) with at least one layer (39) of impervious plastic thereon, which has a crushable ampoule (20) therein containing the liquid to be dispensed. The outer tube is closed at one end and open at the other with an applicator tip (15) of porous foam thereon. A slide ring activator tool (25) of L-shape is carried on the tube and is rotated to break the ampoule and allow the liquid to flow through the tube to the applicator tip from which it is applied to a surface. The tool has forks (36) that may be moved to extend along each side of the tip to act as a guide for the applicator.

Abstract: An eraser for removal of dry ink dust and for conditioning of white boards, which includes a stack of fabric layers which may be treated with cleaning and anti-static compounds. The fabric layers are of semi-rectangular shape which wrap around a jacket cover which is folded over a center core and joined together, the fabric layers have tab dispensing ends and other ends which are fastened to the cover and core by a single staple which spans the ends, the ends to permit the layers to be removed one at a time.

Abstract: A ratchet handle of generally spherical shape, the handle having an embedded ratchet mechanism near one surface, the drive post of which is accessible through a diametrical channel extending from the opposite side of the sphere. An extension rod inserted into the channel mates with the drive post and extends beyond the opposite surface of the handle a selected distance to a socket wrench which may be used to drive a fastener of corresponding size. Supplemental male and female post recesses accept additional extension rods serving as lever handles and fixed, non-ratcheted drives.

Abstract: Marker pen devices for dispensing moisture sensitive or volatile liquids, which include an outer tube open at one end, of rigid plastic or aluminum with a sealed glass ampoule inside the tube which has liquid therein to be dispensed which may contain a metallic glass ball for mixing and/or breaking the ampoule for freeing the liquid, for dispensing through a spring action nib valve, which closes off the open end of the tube, and in an alternate embodiment may have an externally mounted slide ring activator to distort said tube and crush the ampoule.

Abstract: An applicator for dispensing liquids which comprises, a thin walled elongated tube like plastic container which has an ampule therein which contains liquid to be dispensed. The container has an opening at one end with a sponge thereon, and a slide ring activator mounted to the tube, which is restrained from longitudinal movement by positioning bumps, which slide ring for applicator activation is rotated about the tube's axis to apply inwardly directed forces on both sides of the ampule to cause it to break, and liquid to flow to the opening, and thence to the sponge from which it is applied.
