Abstract: A locking system for drawers may include a lock with a lock driver that is configured for engaging a drive actuator. The drive actuator may have a lock bar slider in communication with a lock bar. A slave actuator may also be provided in communication with the drive actuator through a shaft. The drive actuator and slave actuator may be respectively positioned so as to lock opposite ends of a drawer. The locking system may also provide the lock with a lock driver that is prevented from being moved into a locked position when the drawer is opened. One of several different resulting arrangements prevents unintentional or inadvertent locking until the drawer is placed into engagement with a drive actuator.

Abstract: Disclosed are apparatus and methodology for reducing noise and wear in a flapper configured exhaust tip for a marine exhaust system. A flapper, normally located within an exhaust tip of a marine exhaust system, is relocated upstream of the point in the exhaust system where cooling water normally contacts the exhaust pipe. An exhaust tip is coupled to the upstream portion of the exhaust system by way of an elastomeric coupling device. The flapper is positioned such that a tip thereof contacts the elastomeric coupling rather than the metallic exhaust pipe. Such contact with an elastomeric coupling device reduces noise previously produced by flapper contact with the hot exhaust pipe occasioned by destruction and/or heat degeneration of elastomeric material generally associated with the flapper device.

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.

Abstract: Disclosed are apparatus and methodology for fine tuning the fit and function of a cam lock used to secure an enclosure or similar. A cam lock is provided with a cam and a set of variously sized adjustment pads that may be individually secured at one end of the cam. The adjustment pads each differ in thickness, and are installable on the cam without the need of tools. The variously sized adjustment pads allow field installation and adjustment of the position of cam contact surfaces to easily and quickly adjust positioning for spacing variations due to manufacturing tolerances. Such customized installation provides improved security, reduced noise and rattle of the enclosure door, and a more professional aspect to the installation.

Lock actuated auxiliary cam mechanisms and panel locking assemblies controllable by a single cabinet lock are connected with a cabinet lock by linkage bars or cables.

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.

Abstract: An articulating support arm is used with a work station and has a central body with two ends. The inner end has a base pivotally connected thereto and the outer end has a platform pivotally connected thereto. The platform has an angled abutment that is integral with the platform and is located to be contacted by a slider that moves from side to side on a threaded shaft located on the central body. As the shaft is rotated, the slider slides along the abutment to vary the pitch of the platform relative to the body.

Lock actuated auxiliary cam mechanisms and panel locking assemblies controllable by a single cabinet lock are connected with a cabinet lock by linkage bars or cables.

Abstract: Disclosed is a lock assembly such as for use with enclosures and access panels. The lock assembly includes a keyhole shaped aperture in a slide portion of the locking assembly that cooperates with double-D shaped protrusions associated with a locking plug. In a locked position, the double-D shaped protrusions inhibit movement of the slide portion. In an unlocked position, the double-D shaped elements may enter a more narrow portion of the keyhole shaped aperture and permit movement of the slide. The slide is associated with additional features so that movement of the slide selectively inhibits or provides consequential movement of other elements that in turn respectively deny or create access to an enclosure.

Abstract: Disclosed are apparatus and methodology for providing a resettable manual entry combination and key operated cam lock. Methodologies are provided for enabling changing of the manual entry resettable combination given knowledge of the previous combination and possession of an operable key. In alternative embodiments, provisions are made to prohibit forced opening of the lock by way of the use of foreign objects.

Abstract: Apparatus and associated methodology are provided for key operated pin tumbler locks, some of which may incorporate a removable core pin tumbler lock. A selected tumbler of a type commonly used in pin tumbler locks is configured along with a driver pin to control operation of a retainer that, when rotated by use of a control key inserted in the lock, allows alternate selective removal and replacement of the core assembly in the lock. Also, or separate therefrom, one or more tumbler holes may be formed or drilled in a manner so as to prevent engagement of a tumbler with the bite of a key. Presently disclosed structures and associated methodology help to reduce any susceptibility to unauthorized techniques practiced against the lock, such as unintentional activation of the tumblers by unauthorized persons through use of a key with so-called “bumping” techniques.

Abstract: Disclosed is apparatus and methodology for providing a retrofittable lock assembly for an enclosure. A manually or electronically accessible lock assembly has been provided that may be attached to an enclosure to control access to items stored in the enclosure. In a particular form, the retrofittable lock may be applied to a refrigerator used to store controlled medications. The retrofittable lock contains electronic circuitry that maintains a record of user identification, date, and time of access of users seeking access to items stored in the enclosure.

Abstract: Disclosed is a water cooled exhaust assembly for use in association with an internal combustion engine in a marine environment. Inner and outer nested tubes are affixed to a mounting flange to form, in conjunction with an access port in the mounting flange, a cooling water flow channel to provide cooling of exhaust gases from the engine. The inner tube is formed with a flattened portion to produce a reduction in exhaust gas turbulence in the flow channel with a consequent increase in heat transfer capability.

Abstract: Disclosed are apparatus and methodology for providing an improved pick-resistant lock structure. Contact edges associated with individual combination and driver pins are moved away from the true shear lines to deny a lock picker the ability to feel any contact between a selected pin and a pin hole edge. Methodologies and apparatus are also provided to prevent a lock picker from obtaining an impression of the lock shear plane.

Abstract: An apparatus and a method for use with an electronic locking system is provided. At least one key is selected in order to have access to at least one lock. This key to lock relationship is transferred to a memory of the key. The key is presented to the lock and at least a portion of the key to lock relationship from the key is transferred to a memory of the lock. This transfer updates the memory of the key to lock relationships in the lock. The update of the memory in the lock is noted in the memory of the key. The key may then be placed in communication with a computer so that at least a portion of the memory of the key is transferred to a database in the computer. This transfer updates the database in order to reflect the fact that the memory of the lock has been updated and completed.
