Inventor: HOPKINS DAVID H
IPC: B01D61/10
Filed: 1993-07-09
Abstract: A sandwich of a permeate fabric material within a folded sheet of semipermeable membrane is spirally wound together with a sheet of porous feed pathway material about a mandrel which, upon its removal, provides a central hollow region in the wound element. A single band of adhesive seals the outer end of the envelope, and once wrapping is completed, a thin layer of porous tape holds the winding tight. A porous small diameter tube is inserted into a pocket adjacent the fold in the semipermeable membrane material near the center of the winding and serves as a permeate discharge conduit. Axial ends of the spirally wound subassembly are sequentially potted in resin to complete the basic fabrication of the element. Communication with the feed pathway material is provided by drilling through the resin into the center hollow region. The spirally wound element can be used as a replacement cartridge for a device having a permanent housing, or it can be integrally bonded within a surrounding pressure vessel assembly to form a disposable water purification unit. Feedwater supplied to the open center region flows spirally outward, while permeating purified water flows spirally inward to the porous tube which serves as a pure water discharge conduit.

Abstract: An image display device includes an image display unit (4) including a plurality of pixels (10) patterned in a dot matrix in two dimensions and having a path (2) of travel of imagewise rays of light, and the two-dimensional diffraction grating (5) disposed on the path (2) of travel of the imagewise rays of light leading from the image display unit (4). An imaging device also includes the two-dimensional diffraction grating disposed between a      photo-taking lens and a solid-state imaging element. 
     The image display device according to the present invention makes use of a two-dimensional diffraction grating (5) of a type which includes a plurality of grating elements arranged in two directions different from each other and in which the grating elements in one on the directions have a substantially uniform grating height when viewed in an arbitrarily chosen section along such one of the directions and, also the grating elements in the other of the directions have a substantially uniform grating height when viewed in an arbitrarily chosen section along the other of the directions. 
     With this structure, since the two-dimensional diffraction grating disposed on an optical path (2) of an image display unit has respective patterns of grating elements arranged in the two directions extending at an angle relative to each other, rays of light incident upon the two-dimensional diffraction grating are diffracted in two dimension. As a result thereof, the diffracted light is diffused into the shades of non-transparent portions of the pixels in the image display to improve the quality of the image being viewed.

Abstract: An adjustable elastomer torsion device includes a base member aligned in partially nested relation with a resilient elastomer (e.g. rubber or urethane resin) torsion member; parts of the base member and the torsion member overlap each other and an extension portion of the torsion member projects beyond the base member. The base member and the torsion member are interlocked, where they overlap each other, to prevent relative twisting between them, but the interlock does not interfere with twisting of the torsion member extension. An adjustment mechanism provides for adjustment of the positions of the base and torsion members relative to each other to vary the length of the extension portion of the torsion member over a given displacement length and thereby adjust the elastomeric, resilient torsional restoration force (torsional resistance) of the device within a predetermined force range. In some versions, the base member is a resilient elastomer, so that some twisting occurs in the base member; in others the base member does not twist preceptibly.

Abstract: A modification of a cold milling machine used to remove concrete and asphalt from an existing highway is disclosed, including a milling drum segmented into two or more sections with the drive train for the milling drums passing through the core of the milling drum and supported via a journal or bearing to the outside of the machine. One or more sections of a milling drum may be added to the drum to vary its length. The sections of the milling drum can be added by bolting segments of the drum onto a driven sleeve which telescopes over the drive shaft of the machine. The segments of the milling drum can be readily removed by loosening a few bolts and removing the segments without having to slide a milling drum segment off of either end of a drive shaft. A segmented moldboard is also disclosed which allows the moldboard to be adjusted in segments, depending upon the cutting width of the milling drum of the machine. The segmented moldboards can be bolted together and are hydraulically operated between an operating position and a docking position. The hydraulic structure of the moldboards also allows the segments of the moldboard to float on the surface of the road or highway at a height depending upon whether or not the moldboard is following a portion of the highway that has been cut or a portion of the highway that is undisturbed.

Abstract: Monitoring of optical amplifiers (420-1,---420-6) is accomplished, in accordance with the invention, by an apparatus and method for detecting a power level of a tone modulated upon a signal input to the amplifier, detecting an output power level of the amplifier, and comparing the power level of the tone to the output power level of the amplifier to determine an indication of the performance of the amplifier. 
     In illustrative embodiments of the invention, each of the individual channels within a multiplexed optical signal are modulated with a specific low-frequency tone (f₁,f₂,f₃,f₄). The modulating is performed at the transmission site (400-1,---400-4) of the optical signal, and the specific tone frequencies are chosen to be lower than the low-frequency cut-off of any other information encoded upon the optical signal. The channel power of each channel is determined after each stage of optical amplification in the network by measuring the power of its respective unique low-frequency tone using a low-cost monitor (250). The total optical output power of the optical amplifier is also measured by the monitor. The ratio between the tone power and the optical amplifier output power after the first stage of optical amplification in the network is compared to the tone power/output power ratio at each subsequent optical amplification stage. Changes between the first and subsequent tone power/output power ratios reflect changes in network performance. The changes in tone power/output power ratio are strongly correlated to actual changes in optical signal-to-noise ratio. Advantageously, such a monitor may be built-in to each optical amplifier in the network, and no complex calibration of any components in the network is needed. Since each optical amplifier has a dedicated monitor which determines the status of each channel, faults in the network may be readily and quickly located to a specific optical amplifier and a specific channel.
