An alpha-halocarbo aromatic monomer or comonomer and/or an allyl halide monomer or comonomer can be reacted with aluminum or an aluminum-containing catalyst to form a polymer.

Polymer

Sensor switch includes a compromisable mechanical restrainer and a biased member. Before compromise, the restrainer can hold the biased member in a first position. When contacted with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased member can assume a second position different from the first position. Monitoring a sample for a target chemical and/or composition can be carried out with the sensor switch.

Sensor switch for chemical/composition detection

Composition has an indicating dye encapsulated by an encapsulating material. An encapsulated indicating dye can be combined with an organic substance absorbent and/or adsorbent. The composition, combination and/or a device having one or both of them can be used to indicate the presence of an organic substance by contacting the same with a sample, and, ascertaining whether an appropriate color release occurs to indicate the presence of the organic substance by contact of the organic substance with the composition, combination and/or device.

Visual spill indicating

Composition, which includes a dye that changes color when contacted with a suitable amount of an organic substance, in conjunction with a matrix, paste, support or web, can indicate visually or photometrically the presence of the organic substance. An organic spill absorbing material may be present. For instance, the dye may be selected from the class of anthracene, azo, anthraquinone, pyrazolone, and quinone dyes, and be hydrophobic and organic oleophilic. For an example, the dye may be Oil Red 'A.' The matrix, paste, support or web may include a microfiber cloth, which may be coated with an adhesive for attachment of the dye, and/or include a water-dissolving paper which may envelope the dye. A device for ascertaining whether an organic substance is present includes the dye or composition with the dye at a certain locale, and a light-transmissive pathway in communication with the location and a detection site external the location. A spectral instrument may be included for the detection, and a remote monitor site may be in communication with the instrument. Various organic substances can be detected, to include oils and gasoline.

Inert gas blanket protects oxidatively labile substance from oxidation. For example, fuels and lubricants such as present in fuel tanks, bearings, crankcases, gear boxes, transmissions, and so forth, employed in or in conjunction with internal combustion, jet and turbine engines, or a combustible substance such as flour dust in a grain silo, can be protected with a nitrogen blanket provided from the separation of air with a membrane containing device. Useful life of oleaginous liquids and hydrocarbon-based lubricants can be extended. For example, with the practice of the present invention, it may be necessary to change automobile engine oil only after twenty to fifty thousand miles of use.

Inert gas blanket for protection from oxidation

Solid composition has an organic spill absorbing material in which is absorbed certain of a liquid organic compound or composition. The organic spill absorbing material can be water insoluble, particulate polymer particles that imbibe liquid organic materials. A halogenated organic can provide the liquid organic compound or composition. The halogenated organic can be a halogenated hydrocarbon. A fire can be fought by transmitting the solid composition containing a suitable flame retardant to the base of the fire under conditions such that the absorbed liquid in liquid or vapor form is released; and a living target can be stupefied by transmitting the solid composition containing a suitable stupefying agent under conditions such that vapors of the stupefying agent are released and stupefy the target.

Imbibed organic liquids, especially halogenated organics

Heat-inhibition respecting a motor is provided in connection with a heated instrument through a stand-off mount system and/or a heat-inhibiting rotor/stirrer. The instrument can be a hot bath containing instrument where stirring of the contents of the bath can be carried out, for example, a kinematic viscosity bath device, which may include the stand-off mount system and heat-inhibiting rotor/stirrer in which is present a convoluted path for heat conduction and/or increased air flow generator between the surface of the bath and the motor.

Heat-transfer-inhibiting motor and rotor

Device for direct refrigeration has heat-conductable solid member with refrigerant passageway coursing through or about; and at least one test sample well in or in proximity to it, at least one solid, heat-generating member affixed or in proximity to it; and/or optional component(s) and/or feature(s). Heat-conductable solid member may have opposing refrigerant flowpaths containing conventional cooling material(s), for example, air, liquid methanol or ethylene glycol, but preferably, refrigerant for direct refrigeration. The member may be, for example, a block of copper and/or other material with a high heat-conductance, with one or more test sample well(s) for insertion of test sample cell(s) for low-temperature rotary viscometric yield stress testing of engine oils, or other testing. Heating may be employed. Dynamic temperature control can be facilitated by temperature sensor and/or controller system, with sensor(s) and/or heating element(s) strategically placed in or on the block. The device may be augmented or conjoined with or to a solid block thermoelectric cooling/heating contrivance which operates by the Peltier effect. Radially endowed correspondent cell pin and rotor bottom cup arrangement can for practical purposes provide nearly friction free action, essentially unencumbered by water/ice interference. Dry gas blanket delivery system and rotor key arrangements are provided as well.

Direct and/or opposing flowpath refrigeration

Thin film thermal oxidative engine oil or other oleaginous liquid deposit device has an oleaginous test liquid placement volume; a heatable depositor surface in liquid communication with the volume; a supply for at least one of an oxidant and another substance which can adversely affect the test liquid; and a relatively thin film forming unit which delivers the test liquid to the depositor surface in a relatively thin film. Thin film thermal oxidative engine oil or other oleaginous fluid deposit method is also provided, which includes providing an oleaginous test liquid in an oleaginous test liquid placement volume; providing a depositor surface and heating said surface; delivering the test liquid as a relatively thin film to the heated depositor surface; providing to the test liquid an oxidizing and/or other substance which can adversely affect the test liquid; and observing any deposits or other activity thereabout. The invention is useful in oil testing.
