A firearm safety lock for positioning in the chamber of a firearm and preventing the firing of the firearm until the device is removed from the chamber. The firearm safety lock includes an elongate housing for positioning in a chamber of a firearm, and having a longitudinal axis extending between the opposite first and second ends. The housing has an interior and the second end thereof has an opening. A first end member is mounted on and protrudes from the first end of the housing. A lock channel extends from the housing. A second end member is mounted on the second end of the housing. The second end member is slidably mounted in the interior of the housing. The second end member has a retracted position wherein the second end member is generally retracted into the interior of the housing and an extended position wherein the second locating member is generally extended from the second end of the housing for engaging a second end of the chamber of the firearm to lodge the housing in the chamber and preclude removal of the housing from the chamber. A locking mechanism is provided for moving the second end member between the retracted and extended positions. The first end member has a substantially frusta-conical portion for centering the first end member in a first end of the chamber of the firearm and wherein the second end member has a substantially frusta-conical portion formed on the second end of the body member for centering the second end member in the second end of the chamber of the firearm.

The invention is of a new design for a room air conditioner. An air conditioner according to the present design will emit a substantially lower operating noise level than units of comparable cooling capacity and energy consumption. Additionally, the present design prescribes a coil design which requires approximately one-third less aluminum and copper than similarly performing room air conditioner units. The benefits of the present design arise from its reliance on a single row, wrap-around coil design which is used in conjunction with a tangential blower assembly. The single row evaporator coil of the present invention inherently produces less 'wind noise' than multiple row coils. The positioning of the blower relative to the evaporator coil (the blower is enveloped by the coil in the preferred embodiment) and the positioning of the evaporator coil relative to the inner wall of the unit (which separates interior from exterior space) causes room air to flow into the space defined by the wrap-around evaporator coil from all directions, including the space adjacent to the inner wall, which air flow reduces the temperature gradient across the inner wall and reduces chassis insulation requirements.

Room air conditioner design

An air conditioning unit comprising a refrigeration assembly, an air handling assembly, and a control assembly. The refrigeration assembly includes a generally rectangular base pan having upturned edges and a floor having a raised section, the base pan having a condenser, an evaporator, and a compressor mounted to an upper surface thereof. The air handling assembly includes a bulkhead having adjacent side wall portions, a scroll, a motor having an output shaft, a motor mount bracket for engaging the base pan of the refrigeration assembly, a fan, and a blower engaging the output shaft of the motor, a fan shroud and struts for mounting the shroud to the bulkhead and an air plenum assembly. The control assembly includes a control housing and a control panel.
