摘要： A detector and detection method for identifying unknown chemical solutions following chemical spills includes a specific gravity detector including a detector column having an inlet end operable to collect a sample of a solution, wherein the detector column is formed of an optically transparent material to allow visual observation of the sample in the detector column. At least a first plurality of specific gravity floats including a first specific gravity float is located and moveable within the detector column, wherein the first specific gravity float has a density to float in liquids having a specific gravity of greater than a first density level. At least a second specific gravity float is located and moveable within the detector column, wherein the second specific gravity float has a density to float in liquids having a specific gravity greater than the first density level. A sample of an unknown solution from a site of a chemical spill is introduced into the detector column. A float response of the first plurality of specific gravity floats is observed and based on the observation a presence or absence of at least one chemical solution in the unknown solution is identified.

摘要： A means for determining the concentration of a hydrogen-rich fuel in a fuel solution within the anode reservoir of a fuel cell. The fuel concentration is determined using a float responsive to fuel solution density. As fuel is consumed, the fuel concentration decreases. As the fuel concentration decreases, the density of the fuel solution increases, causing the float to rise. A window may be included in the anode reservoir or in an attached float chamber to facilitate inspection of the position of the float. A fuel scale may be included to facilitate fuel concentration determination based on the position of the float within the fuel solution. Additionally, a valve responsive to float position may act to control fuel delivery.

摘要： The battery charge indicator cage is molded as a single integral piece with two cores coming in and shutting off against each other. The battery charge indicator cage includes an internal diagonal channel in which a colored ball or balls traverse dependent upon the presence of a fluid of at least a predetermined density. A stem is formed within the diagonal channel in order to form the one-ball embodiment. This stem is removed in order to form the two-ball embodiment.

摘要： A system and sensor for remotely monitoring the state of the condition of the electrolyte within each of the battery cells of a power supply is disclosed. The system includes a sensor having a dual ball-float and track arrangement for shuttering a pair of light sources and so as to independently detect and differentiate predetermined low electrolyte specific gravity and a low level of the electrolyte. Two multiplexing units receive the sensor signals and display separate indications of each battery and the states detected. The detector uses a gravity responsive ball disposed within a track that shutters one light source at a predetermined low specific gravity and a second level responsible ball within a second track located above the gravity track and ball. The level ball has a specific gravity which is less than that of the specific gravity responsive ball and shutters the second light source at a predetermined low electrolyte level independently of changes in the specific gravity of the electrolyte.

摘要： THIS INVENTION RELATES TO A DEVICE FOR DETERMINING PRINCIPALLY THE CHANGES IN SPECIFIC GRAVITY OF A FLUID ON A CONTINUOUS BASIS. THE DEVICE INCLUDES A VERTICALLY EXTENDING CHAMBER CONTAINNG A PLURALITY OF FLOTABLE ELEMENTS. EACH ELEMENT IS ADPATED TO FLOAT AT A DIFFERENT SPECIFIC GRAVITY. AS FLUID PASSES THROUGH THE CHAMBER, FIRST ONE AND THEN ANOTHER ELEMENT WILL FLOAT OR SETTLE, DEPENDING UPON THE SPECIFIC GRAVITY OF THE FLUID. CHANGES IN SPECIFIC GRAVITY OF THE FLUID WILL BE INDICATED BY THE RISE R FALL OF THE ELEMENTS IN THE FLUID.
