An inline motorized lock drive is mountable within a lock housing to drive a sliding locking element between a locked and unlocked position. The lock drive includes a reversible motor having a shaft with an auger thereon to drive a lock spring, which drives the locking element. The sliding motion of the locking element is axially aligned with the motor axis to substantially reduce friction. The lock drive is preferably modular and emulates a solenoid lock drive with a control circuit. The control circuit is connected to drive the motor is switchable to default to a locked position or an unlocked position and emulate a 'fail safe' or a 'fail secure' type solenoid lock drive. The control circuit operates on 12 or 24 volts to replace solenoid locks of either voltage and stores power when power is applied, then uses the stored power to return the lock drive to the selected default state when power is removed.

A release mechanism is actuated by the heat of a fire to electrically and mechanically disconnect electrical wiring from an electronic lock having a plastic housing. The electronic lock is mounted on a fire door and as it is heated by a fire on the opposite side of the fire door, mounts that hold the lock melt, releasing the electronic lock to drop away from the fire door and prevent ignition of the plastic housing. The release mechanism may use shape memory alloy wire to contract and disconnect a ribbon cable. Solder connectors may also be used to disconnect wires. Intumescent material that expands when heated is used to drive the lock mechanism away from the fire door and insulation is used to control the timing of melting.

A pair of bicycle tire levers comprising: an outside lever, the outside lever having a main body and a tapered end on one end of the main body, the outside lever comprising: an unthreaded compressed gas cartridge clearance hole located on the main body, and an inside lever, the inside lever having a main body and a tapered end on one end of the main body; the inside lever comprising: a threaded compressed gas cartridge hole located on the main body and configured to allow a compressed gas cartridge to screw into the hole. A compressed gas accessory holder comprising: a main orifice body; a threaded main orifice located in the main orifice body, where the threaded main orifice is configured to allow a compressed gas cartridge to screw into the main orifice; a slotted body attached to the main orifice body, the slotted body comprising: a main slot.
