Abstract: A multifunctional infrared spectrometer system has an interferometer which receives the infrared beam from a source and provides a modulated output beam on beam paths to multiple spatially separated infrared detectors. A multi-position mirror element mounted at a junction position receives the beam on a main beam path and directs it on branch beam paths to sample positions, with the beam then being directed on the branch beam path to one of the detectors. One of the branch beam paths may include a sample holder at the sample position which can index between a position at which a sample is analyzed, to a reference material position, to a pass-through position for calibration purposes.

Abstract: An output circuit has multi-stage protection circuitry for protecting against different fault current conditions. The protection circuitry operates by detecting voltage changes across the output transistor of the output circuit. The output circuit comprises first, second and third switching devices. The first switching device is connected to the output device and power conditions the output signal. The second and third switching devices override the output signal and turn off the first switching device when a magnitude of current through the first switching device exceeds predetermined magnitudes for predetermined amounts of time. A protection circuit is also disclosed which has a sensing device that senses a current flow condition by sensing a voltage drop produced across two terminals of the first power conditioning transistor, the two terminals being the terminals through which the current flows. Advantageously, the output circuit utilizes highly flexible two-stage protection circuitry.

Abstract: Sensing apparatus is disclosed which allows for the determination of the presence, absence or percentage of a conducting medium such as water, by electronic means. The inventive apparatus negates the effect of a false signal generated by contamination of the sensing apparatus. The inventive sensor comprises three or more sensing members attached to a non-conducting substrate with electronically significant distances between pairs of sensing members. An appropriate electrical circuit is connected to the sensing members which converts signals output from the pairs of sensing members into readings which indicate the presence or absence of a conducting medium, notwithstanding the presence or absence of contamination between the sensing members.

Abstract: A dual compartment container assembly having two adjacent compartments separated by a common wall segment. The container includes a discharge end on the container which is operable to permit dispensing of the contents of the container. The container also includes a filling end on the container which is sealed after contents are placed in the compartments. The adjacent compartments have outer arcuate walls extending from junctions with the common wall segment to form bellows like compartments with the arcuate walls being joined at each junction with the common wall segment to form axially aligned pivotal junctions. In a preferred embodiment, the common wall segment is pleated to have a first length prior to filling and a second unpleated longer length after the filling end is sealed. This forms a straight line seal at the filling end and defines the bellows part of the compartments which therefore taper outwardly from the straight line seal to the discharge end of the container.

Abstract: A dual compartment container assembly which comprises a container having two adjacent compartments defined by a common wall and a pair of outer arcuate walls. The container has a filling end which is sealed after contents are placed in the compartments and, of course, has a discharge end at the other axial end of the container. The common wall is pleated to have a "s" shaped curved first width prior to filling and an straightened longer width forming a straight line seal at a point spaced from the filling end. The outer walls and the common wall terminate axially at the filling end to provide a filling end seal region. Pressure forms the seal at the filling end by joining the ends of the outer walls and the seal includes the end of the common wall in the seal. The outer walls are joined with the common wall to form axially aligned pivotal junctions to define bellows by causing the compartments to taper outwardly from a point axially inward from the straight line seal.
