Abstract: A cabinet in which the closure or door thereof is rendered less vulnerable to unauthorized tampering which seeks to bypass the lock thereof as a result of the door being latched behind an edge of the cabinet front opening. Thus, opening of the door contemplates a compound movement, i.e. an initial unlatching sliding movement, and then the usual pivotal traverse from its closed into its open position. As a significant improvement, the construction of the within cabinet effectively masks the presence of the structural features which contribute to the door compound movement, whereas this is not the case with prior art cabinet doors and, as a result, such omission in an obvious way, detracts from the effectiveness of the security intended to be gained by the compound door movement.

Abstract: A self-retaining roof bolt comprising an elongated U-shaped member having a pair of spaced legs which support a flat plate fitted over the U-shaped member and are held under transverse tension at ambient temperature by a grouting which becomes malleable at elevated temperatures. The roof bolt is installed in a roof hole by momentarily heating the leg sections, which causes the grouting to soften, releasing the tension on the legs and allowing them to separate and wedge against the roof hole walls. Thus, the bolt retains itself in the roof hole while the grouting cools. Upon cooling, the grouting re-solidifies, firmly securing the bolt.

Abstract: Integral with a high speed, computer control banking machine is a depository system to provide a fully automatic teller station. At the customer interface there is an entry gate controlled to an open position by a solenoid actuated in accordance with computer generated signals. A deposit envelope inserted through the entry gate is detected by a light sensor as it moves along a pinch roller transport extending to a printing station. An envelope transported to the printing station is held in a fixed position while a numeric print machine is actuated to imprint on the envelope identifying data. When the print cycle is completed, a computer generated signal energizes a solenoid to open a security door to a storage bin and reactuates the pinch roller transport to deliver the envelope into the storage bin. A sensor is activated when an envelope enters the storage bin and the security door is closed and locked as the trailing edge of the envelope passes the sensor.
