Abstract: A polymeric film and process for making same, the film comprising residues of 5(6)-amino-2-(p-aminophenyl) benzimidazole, aromatic diamine, and aromatic diacid-chloride, in the form of polymer having a polymer chain including a salt of formula I, wherein C+ is a sodium, potassium, or calcium cation, the film having a thickness of about 1 to 50 micrometers, and a dielectric constant of 4.5 or greater at 2 GHz in the absence of any particulate additives that increase the dielectric constant of the film.

Abstract: A filled polymeric film comprising polymer and an inorganic dielectric constant-enhancing additive, the filled polymeric film having 12 to 75 percent by weight of said inorganic dielectric constant-enhancing additive, based on the total weight of the polymer and said inorganic constant-enhancing additive in the filled polymeric film; wherein the polymer comprises imidazole groups; and wherein the filled polymeric film has a filled film tenacity that is 70 to 100 percent of a neat film tenacity of a polymeric film having the same thickness made from the same polymer but without the said inorganic dielectric constant-enhancing additive.

Abstract: A sensor is configured to sense a parameter of an aqueous liquid. The sensor has an analog output port configured to provide an analog signal indicative of a sensed parameter, and a calibration memory device storing individual digital information indicative of a calibration of the sensor. A digital output port provides a digital signal indicative of the digital information. A treatment system and method is matched to the sensor.

Abstract: Methods, ovens, and associated apparatus. Ovens and methods are adapted for maintaining the quality of a pre-cooked food product. Rapid temperature and/or relative humidity restoration may be used. Ovens may include a partition movable to vary sizes of oven cavities. Ovens may include removable interior panels. Humidification mechanisms are adapted for generating water vapor which may be used to maintain the quality of a pre-cooked food product.

Abstract: A system includes an oven and an apparatus configured for holding at least one food item and being inserted in a cavity of the oven through an open end of the cavity. A baffle provided on the oven or apparatus has a height extending between the peripheral rim and an upper wall of the oven cavity for restricting flow of gas out of the cavity from the apparatus. Various forms of baffles may be used. The baffles may have adjustable, interchangeable, fixed position, or other configurations.
