Abstract: An optical multiplexer/demultiplexer (11) provides for arbitrarily closely spaced wavelength channels (18, 19, 21, 22), the spacing and locations thereof being determined by the thickness of birefringent crystals such as, for example, quartz. Such a device can also be used for duplexing bidirectional signals. Methods for mechanically tuning the devices to given laser wavelengths are described, as well as simplified constructions which can be used with polarized light sources such as lasers.

Abstract: An improved front assembly for a color cathode ray tube having a tension foil shadow mask is disclosed. The faceplate of the tube has on its inner surface a centrally disposed phosphor screen surrounded by a peripheral sealing area adapted to mate with a funnel. A separate faceplate frame means is secured to the inner surface of the faceplate between the sealing area and the target. The separate frame means according to the invention includes a weldable metal supporting by weldments a tension foil shadow mask a predetermined distance from the inner surface of the faceplate. The faceplate-mounted frame means may comprise shadow mask support structures of sheet metal having in cross-section the shape of an* inverted "V", and the shapes of a hollow tube, a rectangle, and a tooth. The shadow mask support structure may also be provided with at least one foot resting on the inner surface of the faceplate for bracing and stabilizing the structure against upset from the high tension of the mask. Further, the weldable metal of the frame means may comprise a separate continuous or discontinuous metal cap or strip and the frame means further including a support structure comprising four discrete rails composed of ceramic with the weldable metal interconnecting the rails to form a generally rectangular unitary shadow mask support structure. The ceramic may also serve as a "buffer" for compensating for the difference in thermal coefficients of the glass of the faceplate and the metal of the cap or strip. The separate faceplate-mounted frame means may have according to the invention a plurality of slurry-passing structures continuous to the inner surface of the faceplate for passing any surplusage of slurry during the radial-flow slurry-deposition process used in screening the faceplate. The shadow mask support structure can also include a first surface for receiving and securing the foil shadow mask, and a second surface inclined from the first surface to the screen area effective to conduct from the screen area any excess of coating material applied during the slurry deposition process. As a result, discontinuities in phosphor application visible to the viewer, and non-adherence of phosphor resulting in wash-off and flake-off, are avoided. An embodiment is also shown in which electrical connection is made between a mask support structure and a screen.

Abstract: A fuel pump apparatus (20) for maintaining fuel flow when the surface of the fuel in a fuel tank (l0) is below a minimum level. The fuel pump apparatus includes a reservoir (54) in the fuel tank and a pump (60) in the reservoir. A motor in the pump drives a first pump (78) which draws fuel from a secondary chamber (l29) of the pump and discharges it to the engine. The motor also drives a second pump (76) which draws fuel from the tank through a primary chamber (l36) and discharges it to the secondary chamber. The excess of fuel discharged by the second pump over the first pump is discharged through a flow orifice (l32) in the pump to the reservoir. At fuel levels below the minimum, a float (l48) controlled solenoid (l56) closes an inlet port (l42) to the primary chamber causing fuel to back-flow through the flow orifice to the secondary chamber to supply the first pump.
