Abstract: A water gauge in accordance with the invention includes a base and a spherical indicator ball. The base includes a container having a side wall, a bottom wall and a post. The spherical indicator ball has a yellow initial signal hemispherical wall and a red final signal hemispherical wall connected to an axle along a circumference. The axle is supported by the side wall of the container. The yellow initial signal hemispherical wall is heavier than the red final signal hemispherical wall. The spherical indicator ball has a channel in the middle of the red final signal hemispherical wall. Initially, the post is positioned into the channel so that the yellow initial signal hemispherical wall is up and visible. The water gauge is positioned on a lawn to be watered. When watering has added a sufficient amount of water to the container to float the ball above the top of the post, the ball is rotated by gravitational force to position the heavier hemispherical wall in the water.

Abstract: The present invention of an opaque dirt shield for covering transparent portions of a sight container includes an obverse cover, a reverse cover, a fastener and viewing flaps. The covers are generally conformal with the shape of the container. The covers may be made integral into a planar mode to be shaped about the container by a user. The fastener secures one portion of a cover or associated structure to a related portion to position and secure the components of the shield with respect to each other and secure the shield onto the container. The viewing flaps allow the visual inspection of the interior of the container. Similarly, illumination flaps allow the illumination of the interior of the container.

Abstract: Fittings for use with one or more loading bearing lines or chains comprising indicia markings on a working portion of the fitting, the markings comprise an inline load position and angular load positions of the lines or chains when used with the fitting.

Abstract: A placemark has mutually magnetically attractive surfaces disposed opposite one another. The magnetic surfaces are connected to each other by a flexible connecting web, such that they can be separated from each other and closed again on opposite sides of a sheet, for example a page of a book. The placemark is held in position on the sheet by the force of the magnetic attraction between the magnetic surfaces. Thus, the magnetic surfaces grip the periphery of the sheet between them. The placemark further comprises preferably a marker web which extends from the connecting web.

Abstract: A method for monitoring frozen products and an indicator for temperature monitoring of the frozen products using one or several liquids with various melting temperatures; the liquids are encapsuled in cavities of an indicator and are frozen in certain geometric patterns. During the melting process these liquids lose their frozen shape. The cavities are at least partially elastic-deformable, and the liquid is forced into certain geometric patterns by means of mechanic deformation of the walls. The deformation of the walls is accomplished by application of a stamp which has been cooled.

Abstract: A self-sticking removable marker arrow system in which a series of consecutive marker arrows are defined either transversely or longitudinally on a strip of sheet material with a pressure sensitive adhesive being applied on the strip on the contact surface of the marker arrows in the area of the heads and at least some of the area of the shafts thereof. Means are provided such that individual marker arrows can be detached from the others on the strip for use as a removable marker or signal on a document and in tailoring and dressmaking and the like.

Abstract: A system for marking hidden utilities such as buried gas lines, valves and the like includes a marker having highly visible indicia indicating the type of utility on one face and which is bonded to a permanent object adjacent the location of the utility. The highly visible indicia is light reflective or fluorescent or both. The indicia are also recessed in the face of the marker for protection. The marker is affixed to a permanent object such as a curb face or surveying monument in the general location of the utility. The indicia on the marker represent the type of utility and the marker may also contain indicia representing the distance and direction from the marker to the utility location. The system can be provided in kit form which includes, in addition to the marker, a bonding material for affixing the marker to a permanent object and a marker for inscribing information relating to distance and direction on the marker.

Abstract: Method and device for direct, non-contact temperature measure of a body. A laser beam is reflected from the surface of the body and detected along with the Planck radiation. The detected signal is analyzed using signal correlation technique to generate an output signal proportional to the Johnson noise introduced into the reflected laser beam as a direct measure of the absolute temperature of the body.

Abstract: A flagger gate for roadway construction sites. The flagger gate includes a base which pivotally mounts an elongated arm. The arm may be pivoted from a lowered position where the arm extends horizontally into a lane of the roadway to a raised position where the arm extends vertically. A first sign member is located on the arm near the free end thereof, and will typically be a stop sign. A second sign is located below the arm between the free end of the arm and the base, such that the sign extends towards the roadway when the arm is raised. A linkage is provided for rotating the signs during rotation of the arm. Specifically, the first sign faces traffic when the arm is lowered, but faces upwardly when the arm is raised. The second sign faces the base when the arm is lowered, but faces traffic when the arm is raised. This eliminates confusion as to which sign to obey.

Abstract: A multi-purpose bookmark adapted to be positioned over the top edge of the book back with an inner leg thereof extending between the pages thereof and a outer leg thereof extending downwardly along the book back outer surface and in contact therewith. Resiliently between the aforementioned legs and a spirally wound section on the outer leg provides the friction to ensure the engagement of the bookmark to the book and page position may be marked by one or more lines extending through an opening in the connecting portion between the two legs. In addition, a pencil or pen holder is provided at the outer leg.

Abstract: An emergency signaling system (10) is provided for simultaneously reflecting electromagnetic energy in two distinct bandwidths of the electromagnetic spectrum. The inflatable bladder (20) includes a first portion (22,24) reflective of electromagnetic energy in a visual portion of the electromagnetic spectrum, and a second portion (30) being reflective of electromagnetic energy external the visual portion of the electromagnetic spectrum. Inflatable bladder (20) is depolyed by applying a pulling force to the lanyard cord (50) which triggers release of a lighter-than-air gas from a cartridge (90). The expansion of the inflatable bladder (20) causes the closure flap (62) of the storage case (61) to be unlatched from the front wall (67), allowing the inflated bladder to ascend therefrom. Inflatable bladder (20) is tethered to the storage case (60) by way of a cord (50), the cord (50) being unwound from the cord storage assembly (70) of storage case (60).

Abstract: There is provided by this invention an apparatus for injecting resin which provides a sealed injection position for uniform injection pressure on the resin and allows the depth of the injection needle to the controlled so that even minute delaminations, cracks, and voids in composite structures may be filled. The filling resin is contained in a syringe which is held in an injector frame. The syringe's needle protrudes from the nosepiece which is threadably engaged in the injector frame so that by further rotation of the nosepiece the depth of injection may be altered. Air lines and inlet ports are provided to urge the plunger of the syringe forward so as to eject resin into the composite structure, as well as to provide an improved seal about the injection position at the surface of the composite structure.
