Abstract: A locking device having an upper portion, a lower portion, and a locking arm prevents a closed door from being opened. The locking arm is pivotably mounted to the lower portion of the locking device and positioned in cavities of the upper portion and the lower portion. A pivot bolt is operatively attached to the lower portion and an end of the locking arm. A locking bolt extends transverse and through the locking arm and through the lower portion for securing the locking arm. The locking bolt has a key or detent, which is received by a corresponding groove in the lower portion. The locking arm extends vertically from the lower portion upwardly above the lower edge of the door, thereby preventing the door from being opened outwardly when in a closed position. The upper portion and the lower portion are preferably bulbous shaped.

Abstract: This invention relates to a security system aimed at closing and locking a cover of an opening of a tank trailer to avoid any tampering of its content and to prove that the content of the tank has not been tampered. The security system comprises a locking member movable between a lock position to prevent the opening of the cover, and an unlock position to allow the opening of the cover. The invention also comprises an actuating device mounted to the tank trailer operatively connected to the locking member for moving it between the lock and the unlock positions. A sealing mechanism engages the actuating device when the locking member is in the lock position to prevent any movement of the locking member. The sealing mechanism comprises a breakable indicator which is broken upon disengagement from the actuating device, thereby indicating that the openable cover has been tampered with.

Abstract: The present disclosure shows a security lock arrangement for a covered access opening. It shows a cable seal lock body housed in the cavity of a housing that is welded to a structure defining a covered access. The cable of the cable seal lock passes through a latch for the access opening cover and through the lock body from which it cannot be removed without destruction of the cable. A new cable is usable with the lock body permanently mounted to the covered access opening structure.

Abstract: An enclosure assembly for enclosing a tamper-evident security seal sealing a hasp assembly comprises a first enclosure portion and a second enclosure portion. A post is coupled to the first enclosure portion for extending through the generally aligned holes of the hasp members of the hasp assembly to secure the hasp members together and position the first enclosure portion behind the security seal. The second enclosure portion includes an aperture formed therein for receiving the post so that the second enclosure member engages the first enclosure portion and covers the security seal. In this manner, the first enclosure portion and the second enclosure portion cooperate to at least substantially enclose the security seal. A latching member secures the second enclosure portion to the first enclosure to limit unauthorized access to the security seal.

Abstract: A computer enclosure locking mechanism. A bracket is disposed near the edge of a first enclosure panel. The bracket includes a latchpin retaining surface and a standoff member. The first panel includes a first latchpin clearance hole. The standoff member includes a lock bar clearance hole for receiving the lockbar of a padlock or other locking device. A retractable latchpin having a longitudinal member and a head is provided. A spring is disposed coaxially around the longitudinal member. A second enclosure panel includes a second latchpin clearance hole that aligns with the first latchpin clearance hole when the first and second panels are brought together at a seam. When the latchpin is retracted, the head rests against the latchpin retaining surface and the longitudinal member extends through the first clearance hole but not through the second clearance hole, thereby enabling the first and second panels to be separated or brought together.

Abstract: The present invention provides for an apparatus and method for securing a computer system. A security loop or tab is attached to a computer chassis and used to engage a cover that encloses at least a portion of a side of the computer chassis. Structure is provided in embodiments of the invention to releasably engage the cover with the security tab and to provide a means of locking the cover on the chassis to prevent unauthorized access to the computer system. Additionally, the securing apparatus is place in a location not readily visible to users of the computer system.

Abstract: A reversible gate and door latch having a striker bar attached to a grip handle and a rear handle. The gate and door latch is locked in a closed position behind a pronged keeper by immobilizing a security plate that slides vertically in relation to the pivoting action of the striker bar. The security plate is held in place by the striker bar, which passes through it, and slides vertically through a upper and lower horizontal stirrup. The slidable security plate is immobilized by placing a padlock or security pin in a security plate aperture. A striker handle is attached to the striker bar in a parallel fashion to allow for facile griping and pivoting of the striker bar by the user. A rear handle secured to the opposite side of the gate or door allows for operation of the latch from opposite the locking side.

Abstract: A safety seal for sterilizable containers that is closed by the temperature prevailing in the sterilizer. The closed seal then indicates the integrity of the container. The sealing mechanism in the illustrated embodiment is a pushbutton 100 that is subject to the force of a spring 102. The spring is made of a memory-retaining alloy that provides tension at a temperature above a transition temperature and forces the pushbutton into a locking state. The container can be opened once the pushbutton has been forced back, but the pushbutton cannot be returned to its locking position until it attains the transition temperature again.

Abstract: A replacement hasp for a railroad sliding door lock mechanism, a kit for making the hasp, and method for making the replacement using the kit are disclosed in two embodiments. The kit includes a member which partially defines an eye, sized to fit loosely about the existing hasp-retaining link on the car, and an eye-completion member arrayed to mate with the first member and form a replacement hasp when affixed thereto, as by welding with shear welds. In the first embodiment, the first member is generally U-shaped and the second member includes a tongue portion which mates between the ends of the partial-eye-defining member such that the two can be "telescoped" together to form a replacement hasp of different lengths to accommodate changes in the door or door jamb of the railroad car. The two main members include furrows extending along the parting lines between them so as to aid in welding the main members together and to form a stronger affixture than is possible under the prior commercial practice.

Abstract: Force-resistant locking devices for electric meter boxes with hinged cove or the like, comprise a stud member mounted to a wall of the box and a flange member received on the stud member, the flange member including a flange overlying a marginal portion of the cover to keep it closed. The flange and stud members together define an opening receiving and fully enclosing a utility lock for securing the flange and stud members together. In one embodiment, the flange member is an angle iron with rectangular metal stock welded to one leg, and the stud is cylindrical and received in an opening through the flange member. The lock-receiving opening intersects the stud-receiving opening and the shear strength of the utility lock holds the locking device together. In another embodiment, the flange member is a section of channel iron and receives a rectangular stud, the lock-receiving opening deployed to utilize the shear strength of the lock.

Abstract: A re-usable envelope having a zip closure which can be locked closed by a sealing device. The sealing device is of plastics material, one part being mounted to the envelope and the other part being engageable therewith, the sealing device only being operable by breaking said other part. The zip tag includes a part for manual engagement to facilitate closing of the sealing device.
