  • Publication number: 20150225149
    Abstract: Disclosed are apparatus and corresponding methodology for securing access to an underground device through use of a locking mechanism to secure the fill cap on underground liquid storage tanks for refined petroleum products such as situated at typical end user fueling stations. A protective shell with integral vapor sealing cap is provided with a three point toggle mechanism, to prevent theft, willful contamination, or other unauthorized access to the underground storage tank fill cap for any purpose while maintaining a vapor seal to prevent the release of the vapor from the tank contents.

  • Patent number: 8727392
    Abstract: Disclosed is a convertible motorized latch that may be configured in either of a slam latch or a dead bolt latch configuration, just by desired selection and replacement of a minimal number of components, and which may be used on new (oem) equipment or in retrofit applications. In either preferred configuration, an electric motor contained within the latch housing operates to open or unlock the latch. Latch closure may be provided by spring actuation in a slam configuration or by further motor operation in a dead bolt configuration. Either present configuration may make use of an electrical feedback switch for signaling latch retraction while the dead bolt configuration may also include a second electrical feedback switch for signaling latch extension. A gear train may be incorporated within the latch housing to provide reduced speed and increased torque from the electric motor.

  • Patent number: 8516864
    Abstract: A latch apparatus for providing secure storage to an enclosure is disclosed. The latch apparatus can include an actuating device that operates to lock or unlock the latch apparatus in response to a control signal. The control signal can be communicated to the latch apparatus through an RF or other transmitted signal or through hardwires connecting the latch apparatus to the remote device. The latch apparatus can be maintained in either a locked state or an unlocked state without having to continuously supply power to the latch apparatus. The latch apparatus can include a latch hook that can be detent biased to both the open position and the closed position while the latch apparatus is in either a locked state or an unlocked state. The latch hook can move from the open position to the closed position while the latch apparatus is in a locked state. The latch apparatus can also have a thickness such that the latch apparatus will fit in the gap in which drawer slide hardware for an enclosure is installed.

  • Patent number: 8240500
    Abstract: Disclosed are apparatus and methodology for securing access to an underground device such as a storage tank. A lockable blocking plate is secured to a filler cap for an underground storage tank in a manner to inhibit access to the filler cap. The locking mechanism is configured such that the lock and blocking plate may freely rotate with respect to the filler cap. The blocking plate may include a side skirt extending to cover portions of the filler cap and, optionally, portions of a standpipe and coupling for the filler cap. Free rotation is enabled by way of an annular groove in a portion of the locking mechanism, and into which groove one or more locking portions may be inserted, or by way of a freely moving swivel boss attached to the filler cap.

  • Patent number: 8199019
    Abstract: Disclosed are apparatus and methodology subject matters for temperature monitoring and controlled access to refrigerated medications. An electronically controlled lock is installed on a refrigerator used for storage of temperature sensitive medications. Lock access is given to individuals having differing levels of access authorization so that user level authorization holders may have access to stored medications. Supervisor level authorization holders may have access to stored medications and may also effect changes in lock settings including setting alarm levels. Alarm levels may be adjusted to monitor temperatures within the refrigerated storage area so that in the case that temperature fall outside preset limits, access to the stored medicines may be had only by those individuals having supervisory access authorization.
