  • Patent number: 7252269
    Abstract: An asymmetrical bulkhead for a pressure vessel, tank or other storage facility is disclosed. The bulkhead is configured so that there is a high region extending past a cylindrical portion of the vessel on one side of the bulkhead, with a contour of the bulkhead transitioning from the high region to a low region within the last cylindrical region. Such a bulkhead configuration allows two cylindrical pressure vessels to be nested together in end-to-end relation so as to occupy a total smaller volume than similarly sized vessels having convex ends, or to construct pressure vessels that contain a larger volume for storage than similarly sized vessels having convex ends.

  • Patent number: 7220186
    Abstract: A finger grip system is provided for obtaining maximum rotation and a resulting pronounced hook when releasing a bowling ball. The system includes drilled holes for receiving a bowler's middle finger, ring finger and thumb, the holes being spaced such that only fingertips may be inserted into the holes. Inserts are placed in the holes, the inserts having a resilient frictional character, and defined therein lips at the corner of a bottom surface and a wall of a central aperture. The inserts are sized to locate the lips such that dominant upward force applied by the fingers and thumb results from contact of finger and thumb tips rather than other parts of the fingers. Force applied in this manner results in increased rotation of bowling balls.

  • Patent number: 7218398
    Abstract: Method and apparatus for testing of LCD panels is disclosed. An LCD panel under test is mounted to a translatable table between a polarization state generator and polarization state analyzer. For each location on the screen to be tested, a continuum of known polarization states are launched through the LCD screen and detected by the polarization state analyzer. Electrical signals representative of such polarization states are acquired by a computer. Within the computer, a model of polarization properties of the LCD panel is developed based on estimations of what the physical parameters of the LCD panel are believed to be. RMS differences between simulated polarization properties and measured polarization properties are minimized by iteratively refining the modeled physical cell properties, at which point cell thickness and other physical parameters of the LCD screen may be deduced.

  • Patent number: 6995666
    Abstract: A system for monitoring a sensor or switch for operation is disclosed. The switch or sensor is coupled to a CELLEMETRY™ transmitter for sending electronic serial numbers (ESNs) encoded with information, and receiving mobile identification numbers (MINs), also encoded with information, in accordance with the CELLEMETRY™ protocol. A microprocessor controls operation of the combination of the radio and sensor or switch. A computerized control center coupled to the Internet provides a connection medium between the cellular system and the control center. When a sensor or switch so connected operates, the radio sends an ESN via the control channels of the cellular system to the Internet, where the ESN is relayed to the control center. There, processing occurs that provides notification to an entity associated with the sensor or switch. Communications from the control center to the radio associated with a sensor are via MIN numbers, and may initiate operation of a device coupled to the sensor.

  • Patent number: 6951633
    Abstract: An ozone generator utilizing an ultraviolet light tube for generating ozone is disclosed. In this ozone generator, efficiency in converting oxygen to ozone is increased by imposing an electrical field around the light tube. This electrical field causes a theta pinch in the plasma of the light tube, increasing luminescence in the ultraviolet spectral range and exciting diatomic oxygen molecules passing through the electrical field. Thus excited, the diatomic oxygen is easier to disassociate and become converted to ozone.

  • Patent number: 6905298
    Abstract: A nut assembly is disclosed that will ensure that the shank of a bolt that features a measurable grip length will pass through the contact plane of adjoining members. The nut assembly also allows the desired compressive force in the adjoining members to be attained by using a telescopic feature of the nut to allocate additional thread action for the bolt, enabling the bolt to be drawn into the nut further than what would be allowed by a standard nut. The adaptability of the nut assembly can eliminate the need for washers or shims to adjust the shank penetration of the bolt. The nut assembly is useful for application in which the specified thread length and the grip length of the bolt is incompatable with the abutment thickness of the adjoining members.

  • Patent number: 6881331
    Abstract: An ozone-based water purification system is disclosed. In this system, a mixing venturi injects ozone and a liquid sanitizer into a stream of water to be treated. Following ozone and sanitizer injection, the stream of water is passed to a contact region where the ozone and sanitizer are allowed to react with contaminants and biota. The stream is then mixed by several mixing devices to allow residual ozone and sanitizer to further react with contaminants and biota. Particularly a counterflow system is employed wherein the stream is directed downward at several points so that bubbles containing ozone are forced to flow upward against the flow, lengthening ozone contact time. Also, the ultraviolet lamp used to generate ozone is mounted so that ultraviolet light therefrom is exposed to the flow water, providing additional sterilizing effects. In addition, a novel mixing venturi is disclosed that mixes a gas containing ozone and a liquid sanitizer into a motive flow of water.
