  • Patent number: 5270189
    Abstract: A fluidized bed reactor system which utilizes a fluid phase, a retained fluidized primary particulate phase, and a migratory second particulate phase. The primary particulate phase is a particle such as a gel bead containing an immobilized biocatalyst. The secondary particulate phase, continuously introduced and removed in either cocurrent or countercurrent mode, acts in a secondary role such as a sorbent to continuously remove a product or by-product constituent from the fluid phase. Introduction and removal of the sorbent phase is accomplished through the use of feed screw mechanisms and multivane slurry valves.

  • Patent number: 5265082
    Abstract: A system uses prevent and detect mechanisms to enable rewritable data storage media to be operated as a written-once-only media. A physical indication of the media casing serves as an indicator of the write-once-only status of the media. A watermark is magnetically recorded on the media at the factory with a portion of the mark detectable by the system and a portion only detectable by returning to an inspection station for verification. This protects against a complete erasure of all data from the media. A segment write status indication serves to indicate the write-once-only status of each segment of the written data. A portion of the written region, such as the preamble or control field of each segment, contains a status mark written randomly within the area as a status indication that the data was written once or multiple times within that segment.

  • Patent number: 5261822
    Abstract: A phantom cornea for calibrating surgical lasers is formed by superimposition of thin-films of alternating colors. After ablation by a laser beam, the resulting spherical cavity appears as a pattern of nested circles whose concentricity and spacing reflect the alignment and intensity of the laser beam. These patterns can be visually or instrumentally analyzed to determine the proper setting of the laser. The calibration cornea can be planar, or arcuate to mimic the natural cornea. The calibration cornea may be mounted in a phantom eyeball including a removable iris of small diameter which constitutes a convenient target for the alignment of the laser beam.

  • Patent number: 5260636
    Abstract: A rechargeable power pack is shaped and dimensioned to be inserted in the battery compartment of an electrical device. The top of the power pack is exactly symmetrical with the battery compartment cover which it replaces. The power pack houses rechargeable power cells, and has a peripheral wall spaced apart from the sides of the battery compartment mounting the battery contact terminal. Flexible prongs project from the peripheral walls to provide a wiping contact with either a spiral spring negative terminal or a stationary positive terminal of the compartment. A top mounted connector allows recharging of the power pack even while in use on the electrical device. Baffles mounted astride each flexible prong avert damage to the prong during insertion of the power pack into the battery compartment.

  • Patent number: 5260520
    Abstract: Apparatus for weighing a vehicle in motion is provided by employing a plurality of elongated fiber-optic sensors defined by an optical fiber embedded in an encasement of elastomeric material and disposed parallel to each other on the roadway in the path of moving vehicles. Each fiber-optic sensor is provided with contact grid means which can be selectively altered to provide the fiber-optic sensors with sensitivities to vehicular weight different from each other for weighing vehicles in an extended weight range. Switch means are used in conjunction with the fiber-optic sensors to provide signals indicative of the speed of the moving vehicle, the number of axles on the vehicle, weight distribution, tire position, and the wheelbase of the vehicle. The use of a generally N-shaped configuration of switch means also provides a determination of the number of tires on each axle and the tire footprint.

  • Patent number: 5251787
    Abstract: A collapsible liquid container is mounted within a pressure chamber, the chamber is pressurized either by an external air pump, or by a manual pump within the wall of the chamber. The pressure inside the chamber causes the wall of the container to collapse as liquid is drawn from it. A check valve mounted in a channel connecting the inside of the pressure chamber to the spout of the container transfers pressurized air into the container when the pressure within the container drops below the pressure in the chamber, in order to evacuate any liquid remaining into the container when the walls have been collapsed to the maximum extent possible.

  • Patent number: 5245833
    Abstract: A refrigeration air conditioning system utilizing a liquid over-feeding operation is described. A liquid refrigerant accumulator-heat exchanger is placed in the system to provide a heat exchange relationship between hot liquid refrigerant discharged from condenser and a relatively cool mixture of liquid and vaporous refrigerant discharged from the evaporator. This heat exchange relationship substantially sub-cools the hot liquid refrigerant which undergoes little or no evaporation across the expansion device and provides a liquid over-feeding operation through the evaporator for effectively using 100 percent of evaporator for cooling purposes and for providing the aforementioned mixture of liquid and vaporous refrigerant.

  • Patent number: 5244096
    Abstract: A method and kit which combines a condom, cleaning implements such as a toothbrush, and a plurality of solutions containing povidone-iodine complex; a before-contact mouth solution, a before-contact body solution, an after-contact mouth solution, and an after-contact body solution. Up to 3 hours before sexual contact, the condoom is applied and exposed skin and condom areas are cleansed with the before-contact solutions an cleaning implements. This includes: hands, mouth, genitals, lower abdomen, upper thighs and rectum. The solutions also produce a coating action that functions as a sustained chemical barrier and a coating which covers minor cuts or abraded areas before sexual contact. During sexual contact, the coating also acts as a lubricant, reducing further abrasions. After sexual contact, the after-contact solutions and cleaning implements are used to cleanse the exposed or potentially contaminated areas and the condom is removed.

  • Patent number: 5237691
    Abstract: Apparatus and method are disclosed for automatically generating computer programs for use in parallel processor arrangements from a user generated block diagram of the program. The system includes a library of parallel program modules and parallel program interface modules, a background manager (glue), a virtual shared memory, and a visual programming interface. Using the visual programming interface, the user selects parallel program modules and program interface modules and specifies operating characteristics information required to implement a block diagram of the desired program. The user then enables the system to create the source program, compile the program and execute the program on the system. The glue manager automatically establishes the communication paths needed to provide communication between the program and interface modules.

  • Patent number: 5236452
    Abstract: An intraocular lens, in the form of a disk, intended to replace the crystalline lens of a patient's eye, in particular after a cataract extraction, comprises on its distal side an aspherical sector extending approximately from the midline of the disk over one quarter of the surface thereof. The rest of the distal side is spherical. The radius of curvature of the aspherical sector varies monotonously between the value of the radius of the spherical sectors and a lower value. Such a configuration allows light rays impinging on the intraocular lens to be refracted at different angles and provides both near the distance vision. The discontinuity at transition between the aspherical sector and the spherical sector is blocked out by dark or etched plastic to eliminate glare. The proximal side can either be a convex surface, a concave surface or a plane.
