Abstract

A tilt detector for accompanying goods to be transported to determine when the goods have been transported in a recommended position without being inclined at an angle greater than a pre-determined angle characterized by a first fluid of a first density, a second fluid of a second density, a horseshow shaped baffle with a trapping end in the form of an inner apex for trapping the second mass under the force of gravity when in a vertical position with its opening end in the opposite direction such that at least a part of the second mass is freed to move out of the baffle when it is tilted beyond a pre-determined angle of tilt; the degree of the sides of the baffle being related to the pre-determined angle of tilt, and a thin container having at least a transparent window for viewing at least the trapping end of the horseshoe shaped baffle for ascertaining if the second mass has been freed such that the tilt detector can be affixed to goods, containers and the like to tell if they have been tilted too much.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A tilt detector for accompanying goods to be transported to determine whether said good have been transported in a recommended position without being inclined beyond a predetermined angle comprising: a. a first fluid of a first density;   b. a second mass of a second density less than said first density;   c. a horseshoe-shaped baffle with a trapping end in the form of an inner apex for trapping said second mass under the buoyant force of gravity when in a vertical position with its open end in the opposite direction such that at least part of said second mass is freed to move out of said baffle when tilted beyond a pre-determined angle of tilt; the degre of the sides of said baffle being related to said predetermined angle;   d. a thin container having at least a transparent window for viewing at least said trapping end for ascertaining if said second mass has been freed; such that said tilt detector can be affixed to goods, containers and the like to tell if they have been tilted too much during transportation and the like; said tilt detector being resettable by inverting to replace said less dense second mass within said horseshoe-shaped baffle.     
     
     
       2. The tilt detector of claim 1 wherein said transparent window is sufficiently large such that both said fluid and said mass are visible. 
     
     
       3. The tilt detector of claim 1 wherein said fluid is a liquid, said liquid is dyed for greater visibility and a chamber surrounds said baffle, said transparent window being large enough for visibility of said dyed liquid for determining the position of said second mass. 
     
     
       4. The tilt detector of claim 1 wherein said second mass comprises a plurality of small pellets. 
     
     
       5. The tilt detector of claim 1 wherein said tilt detector is employed in conjunction with another tilt detector on goods with the angle between the tilt detectors in their vertical position at about 90° such that if one tilt detector is activated by having been tilted too much, it cannot be reset without tilting the other detector too much. 
     
     
       6. The tilt detector of claim 1 wherein said fluid is a liquid, and said baffle has its inner apex at its top end in its vertical operating position for holding said second mass with its open end opening downwardly in operational installation. 
     
     
       7. The tilt detector of claim 6 wherein said second mass is a gas bubble within said liquid. 
     
     
       8. The tilt detector of claim 7 wherein said baffle is disposed within a chamber in said container, said chamber sealingly holding said liquid; said baffle having its dimensions in thickness less than the dimensions of said chamber and having an elevated portion to prevent entry of said bubble into said liquid without careful emplacement from a generally horizontal position of said container whereby said bubble, once freed from said baffle traverses around the periphery of said chamber to afford an indication of tilt beyond said pre-determined angle. 
     
     
       9. The tilt detector of claim 7 wherein said liquid is ethyl alcohol and said second mass is an air bubble within said ethyl alcohol. 
     
     
       10. The tilt detector of claim 7 wherein said liquid is a dyed aqueous solution and said second mass is an air bubble within said dyed aqueous solution. 
     
     
       11. A combination enabling a recipient of transported goods in a container to determine whether said goods have been transported in a recommended position without having been inclined at an angle greater than a pre-determined angle comprising the combination of: a. a goods container having the goods therewithin; a pair of tilt detectors mounted on the exterior of said container for being read rapidly by the recipient; said tilt detectors affording an indication if a tilt beyond the pre-determined andle has been experienced by said container; each said tilt detector consisting essentially of: i. a first fluid of a first density;   ii. a second mass of a second density less than said first density;   iii. a horseshoe-shaped baffle with a trapping end in the form of an inner apex for trapping said second mass under the buoyant force of gravity since the relative buoyancy of said second mass keeps it trapped when oriented correctly; said horseshoe-shaped baffle having its open end opening in the direction opposite its trapping end such that at least part of said second mass is freed to move out of said baffle when said container is tilted beyond a pre-determined angle of tilt; the degree of the sides of said baffle being related to said pre-determined angle;   iv. a thin container having at least a transparent window for viewing at least said trapping end of said horseshoe-shaped baffle for ascertaining if said second mass has been freed; such that the recipient can rapidly view the tilt detectors to tell if said container of goods has been tilted too much; said tilt detectors being resettable when individually removed from said container by individually being inverted to replace said second mass within said horseshoe-shaped baffle of each said tilt detector. .Iadd.       
     
     
       12.  A tilt detector for accompanying goods to be transported to determine whether said goods have been transported in a recommended position without being inclined beyond a predetermined angle comprising: a. a thin container having front and back walls and defining a chamber;   b. a first fluid of a first density substantially filling said chamber;   c. a second mass of a second density different from said first density so as to respond to gravitational force when allowed to do so;   d. a horseshoe-shaped baffle extending between and engaging said front and back wall so as to hold said second mass within a trapping end in the form of an inner apex for trapping said second mass under the force of gravity when in a vertical position with its open end in the opposite direction such that at least part of said second mass is free to move out of said baffle when tilted beyond a pre-determined angle of tilt, the degree of the sides of said baffle being related to said predetermined angle; said thin container having at least a transparent window for viewing at least said trapping end of said horseshoe-shaped baffle for ascertaining if said second mass has been freed by being tilted too much such that said tilt detector can be affixed to goods, containers and the like to tell if they have been tilted too much during transportation and the like; said tilt detector being resettable by inverting to replace said second mass within said horseshoe-shaped baffle. .Iaddend. .Iadd.13. The tilt detector of claim 12 wherein said first fluid is a gas, said second mass is more dense than said gas, said baffle has its inner apex at its bottom end and its vertical operating position for holding said second mass within its open end opening upwardly in operational installation. .Iaddend. .Iadd.14. The tilt detector of claim 13 wherein said fluid is air and said second mass is a disc that slides around within said containers and is held in position in said trapping end of said horseshoe-shaped baffle before being tilted too much. .Iaddend. .Iadd.15. The tilt detector of claim 12 wherein said second mass comprises a plurality of small pellets. .Iaddend. .Iadd.16. The tilt detector of claim 15 wherein said small pellets are more dense than said fluid. .Iaddend. .Iadd.17. The tilt detector of claim 15 wherein said fluid is a liquid, said second mass is more dense than said liquid, said baffle has its inner apex at its bottom in its vertical operational position for holding said second mass and has its open end opening upwardly in operational installation. .Iaddend.
