  • Publication number: 20240117221
    Abstract: Methods of bonding a male element and a female element, the method including applying an adhesive composition to at least the male element, the male element including a first metal; inserting at least a portion of the male element into the female element thereby forming an external interface between the male element and the female element, the female element including a second metal; and curing the adhesive composition to form an adhesive bond between the male element and the female element, wherein the first metal and the second metal are not the same, wherein the external interface of the male element and female element is covered by the cured adhesive composition and the adhesive composition covering the external interface of the male element and female element limits corrosion of at least a portion of the male element, the female element, or both.

  • Patent number: 6042117
    Abstract: A game board has playing pieces. In the form of indicators which are permanently attached to a game board base. A push button approach that simulates the play of well known games is used to effectively move pieces around a game board. The indicators are push buttons that can occupy either of two positions. In the up position the indicator could represent the presence of a piece or player, or that a particular location or region is occupied. The number of push buttons use will depend on the game and its rules. There could be one, two or four push buttons for each region. One push button could simulate the golf tees of a peg board game. Two buttons could be used to simulate a tic-tac-toe game, while four push buttons could simulate a checkers type game. The permanence of the indicators means that pieces cannot be lost.

  • Patent number: 5481254
    Abstract: Group message delivery in a time multiplexed paging system is accomplished by providing in normal message packets a group ring indicator. A paging device collecting a message interrogates the group ring indicator to determine availability of a pending group message. If a group message is available, the paging device can target a dedicated time slot associated with group message transmission. In this manner, a single transmission of a group message is made available to all paging devices of the paging system. In one embodiment, the group ring indicator is a single bit indicating merely availability of a pending group message, the paging device then targeting and collecting the available group message to determine whether the paging device subscribes to that particular group message service. In a second embodiment, the group ring indicator indicates not only availability of a group message, but also the type of group message available.

  • Patent number: 5246854
    Abstract: An attached growth biological reactor for the growth and harvesting of filamentous fungi. The reactor contains a rigid cylinder which is partially submerged and rotated in a biological medium containing nutrients for fungal growth and which as been inoculated with a filamentous fungal medium. The filamentous fungi attaches itself to and grows upon the cylinder wherein it is removed by use of a doctoring blade. The reactor can be operated in a continuous mode by continuously supplying oxygen and nutrients to the reactor.

  • Patent number: 5184949
    Abstract: A gun-type oil burner is disclosed having a motor axially aligned with a fuel pump and a blower at opposite ends. The blower draws air into the burner, the amount of which is controlled by an adjustable air gate. The blower inlet is covered by a removable, protective air scoop. Upon removal of the air scoop, an outside air boot is easily connected to the burner without burner modification. The air in the burner travels along a serpentine path which contains smooth curves and perimetrally disposed protrusions for reducing the velocity of the air flow and maintaining its static pressure. The air flows through an air tube in a helical pattern, mixes with oil and is ignited at the air tube outlet. A fuel nozzle, ignitors and a fuel supply conduit are supported as a burner sub-assembly within the tube by a spider. A preselected stop of a number of removable stops of differing sizes is located on the spider and properly positions the burner sub-assembly within the air tube.
