flow controller operatively connected in flow communication with one another for routing the source air through the separator and which are arranged in a substantially vertical plane within the control box. Because the working components are arranged in a generally planar arrangement, each of the working components is readily and easily accessible.
4804845 LUMINESCENCE DETECTING DEVICES Kenichi Takeuchi, Tokyo, Japan assigned to Sony Corporation A luminescence detecting device including a luminescence sensitive member made of a transparent resin or the like and containing at least two different kinds of organic phosphors dispersed therein. The first organic phosphor is operative to absorb fluorescence from incident radiation such as the index phosphor stripes from a reflex color cathode ray tube, and has a response spectrum which overlaps with the wavelength range of the incident fluorescence. The first phosphor is designed to emit fluorescence in a higher wavelength range upon excitation by the incident fluorescent radiation. The second phosphor is responsive to the fluorescence emitted by the first phosphor since the spectra of the two phosphors overlap. The second type of organic phosphor emits its own range of fluorescence in a particular wave band and can be detected by a luminescence sensing portion of the device to provide a signal which can be used to control the operation of the cathode ray tube.

by an intermediate space (9) containing a fluid, continuous in phase at pressures other than that of the material stored, and pressure measurement equipment (16, 15) enabling the differences in the pressure of the fluid to be monitored. Advantageously, the device additionally features sampling equipment (18, 17) enabling the composition of the fluid to be monitored. The device may be buried, the outer enclosure being then placed against the cement walls (4) of a cavity, which may be a drilled well. The inner enclosure may feature a leakproof skin which is made rigid by the presence in the intermediate space of a porous and rigid filling material in which the fluid can circulate.
4805630 PRESSURE MONITORING DEVICES Philip A Storey, Hertfordshire, United Kingdom assigned to The BOC Group Inc A probe for monitoring the blood pressure of a patient includes a light reflective diaphragm 4 deformable in response to the blood pressure. A single emitter light guide 10 is arranged off-set from the central axis of the diaphragm 4 and directs light at an off-axis region of the diaphragm. A pair of receiver light guides 8, 12 are arranged one on each side of the emitter light guide 10 so that the axes of the light guides lie in or adjacent the same plane as the center of the diaphragm 4. Each receiver light guide 8, 12 receives light reflected from the diaphragm 4 in accordance with movement of the diaphragm 4.

PROCESS FOR NOX CONTROL Sidney G Nelson assigned to Sanitech lnc A process is described for reducing the levels of nitrogen oxides present in flue gases from stationary sources. The process consists of mixing ammonia or methane with the flue gas and then passing the mixtures through a bed of expanded vermiculite, the latter serving as a catalyst for reactions between the nitorgen oxides and ammonia or methane. The reactions result in the formation of nitrogen and water and/or carbon dioxide.
