Abstract: An electronic lock for a safe door is provided with a digital keypad entry device, a mechanical bolt works and associated handle for retracting the door bolts, and a spring biased rotary bolt which engages and precludes operation of the bolt works, such that upon entry of the predetermined code into the entry device, an electric signal causes a solenoid to energize and retract its armature from a blocking position relative the rotary bolt, further enabling the rotary bolt to rotate against its bias in response to mechanical manipulation of the handle by the user to retract the door bolts. Unauthorized operation of the safe handle causes the rotary bolt to be locked into a fixed position, preventing entry into the safe.

The bolt operating release mechanism is a multi-component assembly operable as a unit or relative to each component dependent on the mode of operation. The electronic mode is operably by use of electronic components which include but are not limited to, pressure-sensitive switches, logic circuit, and a circuit mounting board. An electronic combination is generated, retained and operable with the electronic components to open the lock.

Abstract: Apparatuses and methods for selectively absorbing undesirable organic and inorganic vapors and gases from ambient air while providing oxygen level enhancement of the treated air are disclosed.

Abstract: An oxygen generating microencapsulated composition includes an oxygen generating core material and a coating which is water swellable. When exposed to water, the coating ruptures in an exfoliating manner, exposing the core material to water and thereby generating oxygen. The rate of oxygen release from the microcapsule can be controlled by altering wall continuity, thickness, capsule diameter, and coating characteristics. In other embodiments, combustion resistant materials are included in the wall material.

Abstract: A fence lever control device for a combination lock provides a pivoted plate having an arm positioning a spring to normally bias the fence lever of the lock in a position out of engagement with the fence lever operating cam wheel, with an actuator roller mounted to the cam wheel which engages a follower surface on the pivoted plate once on each complete revolution of the cam wheel in a given direction in response to similar rotation of the dial shaft to which the cam wheel is mounted to thereby shift the pivoted plate and its associated spring mounting arm in an over center fashion to place the spring in a position to bias the fence lever toward the cam wheel, movement of the fence lever into engagement with the cam wheel being prevented by engagement between the fence member and the tumbler wheel assemblies when the wheel assemblies are not oriented in a predetermined relationship.
