  • Patent number: 5915407
    Abstract: A ball, inflatable with a gas using an inflation needle, has a substantially hollow gas-impervious skin with an aperture to allow passage of inflation air. A valve member is selectively seatable in the aperture for retaining the gas and allowing insertion of the inflation needle threrethrough and removable from the aperture to allow rapid release of the inflation gas.

  • Patent number: 5118116
    Abstract: The invention describes a dart target device for use with a dart board. In the preferred embodiment, the dart practice device is attached to the bullseye of the dart board and can be rotated around the dart board to overlie different numbered target segments of a dart board. This device may be utilized as a practice device to help a user to become more proficient at hitting the doubles and triples rings of the dart board as well as the bullseye. Alternatively, the device may be provided with various target zones thereon, which would allow the user to play various dart games therewith. The device includes mechanisms to secure it to the dart board at the desired orientation thereon. There also may be included a mechanism to selectively rotate the device on the dart board automatically, to facilitate throwing practice or to provide alternative games to be played with the device.

  • Patent number: 5103427
    Abstract: The present invention is generally directed to an apparatus and method of echo identification wherein the sources of echoes generated from interface boundaries in a medium may be more effectively identified in the processing of obtained waveform data to generate higher resolution in the obtained data. The method of the present invention is particularly useful for performing ultrasound reflectometry and medical sonography by obtaining data representative of a medium being studied and suppressing signals from overlapping echo waveforms generated from obstacles adjacent an object under test. More particularly, the method of the invention enables the sources of such echo waveforms to be more effectively identified to yield an indication of the contribution of overlapping echoes to generate higher resolution data signals. The processing includes generating a power spectral estimate of the data which is utilized to obtain a phase estimate thereof.

  • Patent number: 5095957
    Abstract: A flotation assembly designed to keep an individual afloat in water comprising a size adjustable harness adapted to fit the torso of an individual, to which are attached bottle closure devices. The closure devices are designed to have empty bottles inserted therein so as to form a substantially water-tight seal. The number of attached closure devices, and the size of the bottles inserted therein are chosen so that the degree of buoyancy desired is obtained, given the size of the individual and the purpose for which the buoyancy is required. Different types of closure devices are disclosed.

  • Patent number: 5078120
    Abstract: The invention relates to a cooking oven for mass production of food products and a method for cooking food products. The oven includes an enclosure housing which forms a cooking chamber, having an endless pervious conveyor therein upon which food products are transported through the cooking chamber. The conveyor is arranged to provide a helically extending path over which food products will travel to increase dwell time within the cooking chamber while taking less floor space. A heated gaseous cooking medium is introduced into the cooking chamber and is circulated through an annulus formed by the helically extending conveyor to achieve high heat transfer to the food products being cooked. The oven can utilize steam and/or heated air to achieve varied cooking characteristics as desired and allows substantial versatility in the cooking process.

  • Patent number: 5076229
    Abstract: An internal combustion engine and method of operation is disclosed as having a combustion chamber design which allows for staged combustion within the chambers. The internal combustion engine of the invention is designed as a split chamber, staged combustion engine which comprises a cylinder and having at least two regions formed therein. Within the cylinder is a piston slidably disposed therein to form a plurality of combustion chambers in association with the cylinder, and particularly at least one primary and secondary combustion chamber which are communicable with one another. Fuel delivery is accomplished by fuel injectors or the like associated with the primary combustion chamber, being operable to admit fuel into the primary combustion chamber at preselected intervals and in predetermined amounts. The fuel admitted in top the primary combustion chamber is ignited to begin initial combustion of the fuel as a first stage of combustion.
