  • Patent number: 5971061
    Abstract: A tube-type heat exchanger has a low wear support and drive for a whip rod that orbits over the inner surface of the heat transfer tube to spread a process liquid into a thin falling film. The support and drive includes a conical thrust bearing near the upper end of the rod. An edge of the thrust bearing engages and rolls over a circular rim bearing surface. A stem pin axially aligned with the rod extends upwardly over the rod and through a circular hole in an orbiting drive plate. In one form, the rim bearing surface is formed on the upper edge of the tube, or on the upper edge of a generally cylindrical bearing secured on or over the tube. The thrust bearing is secured between the rod and the stem. A stop disc carried on the stem pin limits the fall of the rod in the tube when the orbiting stops.

  • Patent number: 5956108
    Abstract: Liquid crystal panels are connected to one another with at least one thermoplastic bonding agent. The thermoplastic bonding agent has the same refractive index as the refractive index of two glass substrates respectively serving as a TFT substrate and a CF substrate forming each liquid crystal panel. The liquid crystal panels are heat-pressed to a reinforced substrate through the thermoplastic bonding film which is made of, for example, a thermoplastic polymer. According to this arrangement, the thermoplastic bonding film does not lose its volume when the liquid crystal panels are heat-pressed to the reinforced substrate. Thus, unlike a conventional method where the CF substrate forming the liquid crystal panel is pulled toward the reinforced substrate side, a uniform cell gap can be secured.

  • Patent number: 5953924
    Abstract: An apparatus, thermal storage system and method for heat exchange using a tube-type heat exchanger. A rod or rods are propelled to moves over the inner surface of the tube. The moving rod is in contact with a first process liquid which is adjacent the inner surface as a falling film or by flooding the interior of the tube. The flooded mode is particularly useful where the tube is non-vertical or the heat exchanger is used to make an ice slurry for HVAC systems serving high-rise buildings. Multiple such rod and tube assemblies are operated simultaneously using a drive plate powered to execute an orbital motion in a plane generally orthogonal to the rods. In one form the plate is coupled via a crank to equiangularly space spaced rods in each tube. This form of orbital drive allows the use of a device to develop an auxiliary radial force, such as spring mounts extending between a central, rotating shaft mounted in each tube and the rod or rods for that tube.

  • Patent number: 5939639
    Abstract: A circular membrane diaphragm is edge-mounted on a generally cylindrical housing structure that allows the diaphragm to deform when a differential pressure is applied across it. The housing structure also supports a circular electrode in an internal chamber and in close proximity to the back surface of the diaphragm to form a variable capacitor. The outer side of the membrane is exposed to a second chamber defined by the housing structure and a cover. A tube connects the second chamber to a gas whose pressure is to be measured. The back of the housing structure is exposed to atmospheric pressure and other ambient atmospheric conditions. The housing structure is characterized by double flanges spaced axially by a deep lateral groove. A central cylindrical boss extends axially from the back side of the housing. The outer diameter B of the boss is at least equal to the diameter E of the groove. This housing structure provides the membrane with a high degree of isolation from external pressure fluctuations.

  • Patent number: 5846413
    Abstract: A compact dissolved-air-flotation (DAF) clarifier and clarification process utilize three zones for clarification which operate in sequence in a single clarifier. Raw water with suspended solids enters a flocculator at the center of an annular tank where microscopic air bubbles introduced to the inflow float flocked contaminants to form a floating sludge layer. A first clarification, calming and degassing occur here. The water then flows radially outwardly into the tank where further quiet clarification occurs. A third level of clarification occurs in a lower portion of the tank, specifically, in a set of plate-like lamellae, radial and conical, which form inclined channels where a final clarification occurs. The bottom wall of the tank has a set of apertures which allow a gravity flow of clarified water through a layer of pressurized gas to an underlying collection compartment.

  • Patent number: 5818137
    Abstract: A rotary motor and a rotary magnetic bearing are integrated in a compact assembly that is contact-less. A stator assembly surrounds a ferromagnetic rotor with an annular air gap which can accommodate a cylindrical wall, e.g. of a chamber for semiconductor wafer processing. The stator assembly has a permanent magnet or magnets sandwiched between vertically spaced magnetic stator plates with plural pole segments. The rotor is preferably a ring of a magnetic stainless steel with complementary pole teeth. The stator assembly (i) levitates and passively centers the rotor along a vertical axis and against tilt about either horizontal axis, (ii) provides a radial position bias for the rotor, and (iii) establishes a motor flux field at the rotor poles. Polyphase coils wound on the stator plates produce a rotating flux field that drives the rotor as a synchronous homopolar motor. A rotor without pole teeth allows operation with an asynchronous inductive drive.

  • Patent number: 5624430
    Abstract: Devices and methods are described to facilitate the coupling of two wires introduced into the vascular system at two different points in the body. The coupling enables the formation of a continuous wire entering the body at one point and exiting at another remote point. The device consists of two wires "A" and "B" with a magnetic element attached to one end of each wire. The coupling is formed by the forces of attraction between the magnetic elements. Wire "A" is introduced at one point in the vascular system, for example, in the femoral artery. Wire "B" is then introduced at another point in the vascular system, for example, the axiliary artery. The wires are advanced towards each other under fluoroscopic guidance. The magnetic tips couple once the two wires near each other. The coupled wires are then withdrawn together from either of the two access sites. Once the magnetic coupling exits the body, a single wire is left traversing the vascular system.

  • Patent number: 5601141
    Abstract: A batch thermal cycler for large numbers of biological or chemical samples uses n modules each in good thermal contact with the samples, but substantially isolated from one another, thermally and functionally. Each module carries samples on an upper sample plate. The module has a temperature sensor adjacent the samples, an electrical resistance heating element, and a circulating fluid heat exchanger for step cooling. Heating occurs at a point generally between the samples and the source of the cooling. The modules are individually replaceable. O-rings automatically seal fluid and electrical interfaces. An electrical controller has n simultaneous channels that provide closed loop control of the electrical power to each module. As a method, the invention includes at least one modular temperature zone where the temperature is sensed at a point adjacent the samples in that zone. The samples are heated adjacent the sample plate. Cooling is by a step change. The cooling overshoots a set lower temperature.

  • Patent number: 5567319
    Abstract: Raw feed water is continuously clarified at a large throughput rate in a single, shallow tank using a flotation process carried out simultaneously in multiple sectors of the tank. Raw water feeds into a rotating trough. A fixed manifold system in the trough dispenses pressurized water containing dissolved air to release microscopic air bubbles. A set of headers each radially extend outwardly from the rotating trough. Each header distributes water and bubbles to a sector of the tank with a net zero velocity. A set of rotating extractors each receive clarified water from the bottom of a preceding sector. A set of scoops skim floated sludge from the water in the tank. The sludge is lifted, as by the rotation of the scoop and/or by a pumped conduit, over the rotating trough to a sludge outlet pipe. In one form the scoop has at least two blades each with an eccentrically located, radially extending compartment that receives, lifts, and then dumps the skimmed sludge as the scoop rotates about its axis.

  • Patent number: 5542300
    Abstract: A variable capacitance type pressure sensor with excellent manufacturability center-mounts an electrode on an edge-mounted diaphragm using a metal-glass-metal subassembly. An inner metal post of the assembly is welded to the diaphragm. A solder or flowable cement secures the electrode to an outer metal collar of the assembly with the initial diaphragm-to-electrode spacing set by a temporary shim. The position of the glass and the physical lengths of the metallic members of the assembly are adjusted to provide self-compensation for temperature variations. In a preferred form for low and medium pressure applications, the diaphragm is stamped from sheet metal with a central dimple that resists rotation of the attached assembly and isolates diaphragm deformation stresses from the post-to-diaphragm weld. In a high pressure form, a machined central boss isolates this weld from stress.
