Abstract: Indicator inks, indicators formed by printing or otherwise utilizing the inks and host products utilizing the indicators are disclosed. Reactivity-enhancing adjuvants stimulate enhanced thermal reactivity of diacetylenic or other indicator agents capable of responding to ambient thermal conditions with a visual change signaling an end point.

Abstract: In a printed circuit board manufacturing process, a resist stripping solution blending organic amines with water is used for stripping the photoresist completely from the board. An apparatus for controlling this resist stripping solution comprises a toroidal conductivity controller for measuring the solution conductivity, which correlates to solution concentration. This same apparatus is equipped with a resist stripping solution discharge device for discharging the resist stripping solution and water replenishing device for replenishing water by detecting the liquid level of the resist stripping solution by a liquid level gauge. As the water is replenished, the solution conductivity is lowered; thereby activating the toroidal conductivity controller to add concentrated resist stripping chemistry proportionally to the deviation from the conductivity controller set point. This same apparatus is equipped with a measuring device for measuring the total consumed organic amine reactants.

Abstract: In the present invention, a temperature indicating material is prepared by incorporating, in a rewritable base system which comprises an electron donating compound, an electron accepting compound and a reversal material and undergoes color changes with temperature and time, a thermochromism controller which changes a rate of crystal to amorphous or phase-separation to non-phase-separation rate. Upon color changes with an environmental temperature, the thermochromism controller undergoes crystallization or phase separation to have a function as a place for reaction and contributes to the color changes of the temperature indicating material. The incorporation of the thermochromism controller therefore makes it possible to impart the resulting temperature indicating material with improved sensitivity to temperature at around an environmental temperature and a high S/N ratio.

Abstract: A device composed of (1) a color changing indicator, (2) an optional polymeric binder, preferably having gel forming capability, and (3) an activator solvent system which induces a color change in the indicator when device is frozen, in the region of about 0 to −30° C. An example of the device is an indicator of a fine dispersion of partially polymerized diacetylene of the formula: R—C═C—C═C—R, where R is a substituent group, e.g., 4BCMU where R=—(CH2)OCONHCH2COO(CH2)4H, dispersed in a mixture of solvents, e.g., 96:4 water:ED (ethylene glycol diacetate), with or without a polymeric binder. When the temperature of the device is lowered to the freezing point of water, the activator solvent phase separates out of the mixture and induces a color change in the indicator. The device can undergo an irreversible color change, e.g., from blue to red, when the activator mixture is frozen in the region of about 0 to 30° C.

Abstract: This invention is thus related to a biospecific multiparameter assay employing single molecule detection. In particular, this invention is related to a new method for determination of several different biomolecules simultaneously in the same reaction solution. The method uses a fluorescent label for labelling biospecific primary probes and a combination of other labels, bound to secondary probes. Complexes are formed comprising primary probes, analyte molecules and secondary probes in the biospecific reaction. These single molecule complexes are counted selectively while discriminating the signals from other fluorescent molecules using confocal fluorometry or two-photon excitation fluorometry including an auto- and cross-correlator for the signals obtained from said fluorescent labels.

Abstract: An accurate monitoring of the conditions of a perishable product is achieved by integrating two indicator types - a primary indicator which develops a color change as a result of cumulative time-temperature exposure and a threshold second indicator - into a single device. The combination of the two indicators in the same indicator device provides a human readible signal that gradually and irreversibly develops color as a function of time and temperature and more closely monitors the actual condition of a deteriorative product than does a single indicator. Important features of this integrated monitoring device are reliability and printability. The primary indicator in the system is assisted in color development by the secondary indictor that is set to trigger at a predetermined temperature. When this temperature is reached or exceeded both indicator mechanisms function in an additive mode to cause a break in the typical Arrhenius curve, which a primary indicator alone produces.

Abstract: A color changing device for monitoring the time-temperature storage history, i.e. shelf life, of perishable products. The device is constructed of an activator tape, containing an activator composition matrix, an indicating tape, containing an indicating composition matrix and an optional barrier matrix between the activator tape and the indicating tape. At least one matrix is a pressure sensitive adhesive. The activating composition, e.g. an organic acid such as citric acid, diffuses through the barrier and/or indicating matrix to continuously contact the indicating composition, e.g. an acid-base dye indicator such as 2,2',4,4',4",-pentamethoxy triphenylmethanol, to produce a visually observable color change at the temperature being monitored. The color intensifies with time and temperature, as more activator composition diffuses into the indicating matrix.

Abstract: A moving boundary device for monitoring the time-temperature storage history, i.e. shelf life, of perishable products. The device is constructed of an activator tape, containing an activator composition in an activator matrix, an indicating tape, containing an indicating composition in an indicator matrix in which the matrices are adhered together to form a wedge-shaped composite matrix, preferably by means of a pressure sensitive adhesive. The device operates by allowing the activating composiiton, e.g. an organic acid such as citric acid, to diffuse through the increasingly thicker composite matrix to continuously contact the indicating composition, e.g. an acid-base dye indicator such as 2,2',4,4',4",-pentamethoxy triphenylmethanol, to produce a visually observable color change at the temperature being monitored. The color change appears as a moving boundary at the color/non-color interface which moves transversely along the length of the device toward the thicker end of the composite matrix.

Abstract: A photoactivated time-temperature indicator is based on diacetylenic salts. A thermally unreactive ("inactive") diacetylenic salt (or a mixture of such salts) is mixed, in a polymeric matrix, with a material that generates acid upon exposure to light. Photoexcitation, preferably by UV or near UV light, causes the formation of a thermal reactive ("active") free diacetylenic acid. Following this activation step, a progressive color development occurs at a rate that increases with temperature. The indicator is useful for monitoring the freshness of perishable products, particularly those that require refrigeration.

A normal level of indicators in the lubricant will be established. The lubricant is monitored and periodically sampled to determine the presence of abnormal levels in the amount of indicator material. Since each component or components performing a similar function will be labelled with the same indicator, the presence of a particular indicator in abnormal amounts in the lubricant will direct the machine operator to the precise location requiring repair or replacement.
