Abstract: A security cover for an automatic gate arm protects against disengagement and removal of the gate arm for the purpose of unauthorized entry through the gate. The security cover comprises four walls and a top plate joined to form a housing that encloses a rotating turret and a portion of a drive arm used to actuate the gate. The security cover mounts over the turret using a vertical rod that extends from above the housing to a location within the drive mechanism of the gate arm motor, and a lock that secures the housing and prevents unauthorized tampering with the drive arm.

Abstract: An anchoring device positionable within the ground for tethering an object to the ground includes a base portion having a first diameter, and an access aperture having a second diameter. The first diameter of the base portion is greater than the second diameter of the access aperture. At least one wall connects the base portion to the access aperture. The device further includes a tether having a first end secured proximate the base portion and a second end positionable through the access aperture and connectable to the object to be secured. The tether is fully disposable within the anchoring device and is longer than the distance between the base portion and the access aperture.

Abstract: A security box includes an outer box, an inner box and a lock cable. The outer box comprises a compartment adapted to receive the inner box therein. The outer box further comprises a first lock hole. The inner box comprises a second lock hole, a lock core hole, a lock core and a sleeve. The sleeve has a first blind hole and a second blind hole corresponding to the second lock hole and the lock core hole respectively. The lock core has a blind hole corresponding to the first blind hole and the second lock hole. A lock cable has a lock rod at one end and a lock ring at the opposite end thereof. The lock rod is inserted through the first lock hole, the second lock hole, and the first blind hole to be secured in the blind hole of the lock core.

Abstract: A locking device has a base, a positioning element, a positioning frame, a cable and a lock assembly. The base has a positioning tab and a squeezing device. The positioning element is attached to the bottom of the base configured for the base being attached to an object. The positioning frame is pivotally attached to the base and has a telescopic body. The cable is moveably received in the base and has one end extending out from the base and provided by a hook to connect to the positioning frame. The lock assembly is mounted in the base and detachably locks the cable. Accordingly, a PDA and a charging base can be securely held on the base with the positioning frame and the cable. This can keep the PDA and the charging base from being unauthorizedly moved.

Abstract: A securing apparatus for a personal computer system unit comprises a tough, flexible, elongate cable having two regions spaced apart along the length of the cable. A security connector connects two spaced apart regions of the cable together to form a strap that extends around the system unit. A guide element is secured to the cover or the base of the system unit and guides the strap relative to the system unit and prevents removal of the strap from the system unit.

Abstract: A cover lock assembly for a process transmitter having threadably removable end caps and corrugated outer surfaces is provided for engaging the corrugated surfaces by way of a toothed cover lock which is removably affixed to the transmitter housing.

Abstract: A vertically adjustable extension rail system for a drawer used in a housing having opposed vertical walls with a plurality of horizontally-extending, vertically-spaced guide ribs leaving alternating guide grooves. The extension rail system comprises two spaced apart extension rail assemblies with each extension rail assembly having a carrier rail and a slide rail which are slidably interconnected. A guide arm is mountable at a plurality of vertical levels along each of the slide rails. The guide arms are adapted for being lengthwise slidably received by opposing guide grooves on the vertical walls. A fixed or removable drawer receptacle can be mounted between the two extension rail assemblies.

Abstract: A locking device intended to be mounted on a fuel pipe nipple (15), which is provided with bayonet locking pins, so as to make it impossible to connect a fuel hose coupling to an outboard motor on a boat. The locking device comprises an elongated external sleeve (1), which at one end is provided with an internally situated lock (6) and at the other end with bayonet locking grooves (20,21,22,23) corresponding to the bayonet locking pins (16). The lock (6) has an axially movable locking piston (9) cooperating with an internal sleeve (14) which is axially displaceable inside the external sleeve (1) between a retracted first position, which permits relative interconnection and release, respectively, of the pipe nipple (15) and the locking device, and an advanced, second position in which the bayonet locking pins (16) are kept securely fixed in the bayonet locking grooves (22,23).

Abstract: In a locking device for use with a vehicle having a trunk compartment and a fuel tank filling outlet positioned adjacent and below a vertical lower wall of the trunk compartment, with the vehicle also having a closeable lid member which closes by engaging said trunk compartment lower wall, said device including a removeable cap closure member for the fuel tank inlet which tightens onto the fuel tank inlet by rotational movement and which has a slot in the exterior thereof, and a locking bar element having configured upper and lower portions, with the upper portion being adapted to fit over the top of the trunk compartment lower wall and engage the underside of the trunk lid, and with the lower portion having a lower terminus which is adapted to seat into the slot in said fuel tank filler outlet cap to lock thereby the cap in place and prevent its removal.

Abstract: An anti-theft device to prevent the unauthorized removal of a mounted, flanged object comprising a cover overlying the mounting flanges of the object, a securing device for attaching the cover to the surface upon which the flanged object is mounted and a locking device for preventing removal of the cover from the securing device. The invention is particularly useful in remote oil field and other field uses to prevent theft of industrial machine accessories such as starters, generators, and batteries.

Abstract: A locking device for fuel tanks which blocks the filler neck in the tank. A cylindrical sleeve having an opening through its length inserts into the filler neck below the outer end of the filler neck and is secured by set screws threaded through the sleeve wall into contact with the filler neck. Blocking means comprising a cylinder lock and an annular adapter, when the device is used on large diameter filler necks, fit into the sleeve, blocking the opening in the sleeve and covering access to the set screws. The cylinder lock, which is key-activated, includes an arm which rotates into engagement with the sleeve, preventing removal of the blocking means.

Abstract: A coin handling construction including a housing provided with a cap for closing access to the interior of the construction. Locking means are provided for securing the cap in place on the housing. These locking means comprise a rotatable rod positioned within the housing. First locking elements are mounted on the cap, and second locking elements are mounted on the housing. The locking elements define a surface for inter-engagement of the elements which prevents separation of the cap and housing. The rod is rotatable between a first position for maintaining the locking element surfaces in the engaged condition, and a second position which frees the cap for separation from the housing.
