  • Patent number: 5121952
    Abstract: This invention relates to a one-piece latching device comprising a body of thermoplastic elastomer of specified durometer hardness having a substantially plane supporting surface, which is disposed in slidable relation in a recess or nesting site in a door or supporting panel, which comprises an elongated opening substantially in the plane of the supporting panel. One edge of the body, transverse to the supporting surface, terminates in a latching lip for engaging a striker bar or surface in cam-like fashion. The body is provided on its upper surface with means for providing a manual pull or thrust for retracting the latching lip and causing the body to slide in the direction of its opposite end, which terminates in an elastic spring member. The latter is compressed against an edge of the nesting site on the side opposite the latching lip imposing a spring-bias on the body, which causes it to slide in the opposite direction when the manual pull is released.

  • Patent number: 4884898
    Abstract: This patent relates to pillow blocks, which are constructed to include one or more roller bearings disposed in tangential relation to the primary shaft at one or more positions around its periphery. Each roller bearing is mounted to rotate about its own stud, so that it acts as a cam follower. In some embodiments the roller bearings are disposed singly, or in pairs, in three positions spaced-apart 120 degrees around the periphery of the shaft. A particular feature of the invention is a device for fine tuning the tangential contact between a roller and the surface of the primary shaft by utilizing a flexible bearing support plate supporting at least one bearing. The plate can move radially to control the radial distance of the bearing.

  • Patent number: 4863099
    Abstract: This relates to a thermodynamic electronic actuator for intermittently controlling the operation of a heating and/or air conditioning system for any temperature controlled area when a door or window is left open or ajar. The actuator circuit comprises a normally-closed switch (or switches if used for more than one opening), which initiates operation of a count-up timer to interrupt the thermostat line after a predetermined period whenever a door or window is left open. To restore power, all that is required is to shut the window or door. This actuates a count-down timer that will restore the thermostat line after a predetermined period, assuming the window or door is not reopened, interrupting the countdown.

  • Patent number: 4860142
    Abstract: A flexible magnetic recording medium contained in a protective jacket is used for storing digital computer information. Such a device requires a write/erase inhibit function to preserve the previously stored information. This invention provides that function by the use of a continuously lockable shutter which can be inserted into the containment jacket. The jacket structure provides the shutter-locking channel by using an outside jacket edge and the side flap sealing embodiment to apply lateral pressure, thereby confining the enclosed shutter to slide along the jacket margin. Once so installed into the jacket, movement of this shutter is controlled through an access slot provided in the containment jacket, which slot is remote from the normal notch provided in the jacket, and is unemcumbered by any physical projection in the notch or jacket.

  • Patent number: 4839470
    Abstract: This invention relates to a submersible electrical cable splice, and the method of making the same. It employs a housing sleeve of an elastomeric material which is hollowed out to include a central cavity connected at each of the ends by bores which are of slightly smaller diameter than the cables which are to be connected. In the process of making the splice, one end of the housing sleeve is lubricated, and one of the cables is pushed clear through and out the other end of the housing, where it is joined to the other cable end in abutting relation in a metal crimp connector. The joined cables are then pulled in the opposite direction back through the bore of the housing sleeve, until the crimping connector seats in the central cavity, which is of slightly smaller diameter than the crimping connector, squeezing out the air. It should be understood that a pocket or void or space is to be eliminated or reduced to insignificant amounts.
