Abstract: A safe for a loaded hand gun has a box which includes a receptacle for containing the gun. The receptacle has a bottom providing a mounting surface. A lid is hingedly mounted on the box and is movable between a closed position covering the receptacle and an open position in which the gun is accessible. A locking device normally holds the lid in its closed position, and a touch pad mechanism is operable only by authorized personnel provides for releasing the locking device when access to the gun is desired, permitting the lid to move to its open position. The touch pad may be a numerical touch pad, an alphabetical touch pad or a fingerprint indentification touch pad. The mounting surface has a mounting hole for use in attaching the safe to another structure. A pressure sensitive pad is affixed to the mounting surface at the mounting hole and is positioned to be overlapped by the head of a mounting screw.

Abstract: A lock comprising a hollow cylindrical seat, a cylindrical lock body for insertion into the seat and having a cavity in its exterior surface to accommodate a sphere therein, a screw hood for screwing onto the lock body, the hood having a plurality of cavities on its interior surface to accommodate the sphere, and a cylindrical lock barrel for insertion into the lock body and having a conical recession for accommodating the sphere to permit removal of the lock barrel and for pushing the sphere into the cavity in the screw hood to prevent removal of the lock barrel from the lock body.

Abstract: A door knob and lock assembly having a pair of knobs, a latching bolt operable by the rotation of the knobs, and a turn button to selectively arrest the movement of the bolt to place the assembly in locked condition. A battery operated electrical circuit including a switch operable by the turn button, and a light emitting diode mounted within the door knobs so as to be operable on locking the door to provide a flashing light visible from the outside of the door.

Abstract: A building has at least one security guard post to control the secured building exits, each of which has an unlocking instrumentality, without forbidding their emergency use. When activating the unlocking instrument to open a secured exit, there is a transmission of information to the security guard post and an initiation of a delay during which the security guard can forbid the opening of the exit. The unlocking instrument can also visually indicate events at the exit. The apparatus has an electro-mechanical lock, a sensor which is sensitive to motion of the unlocking instrument, a control line linking each door to be controlled to the security guard post, and a central electronic processing unit. A surveillance circuit responds to the sensor. A security circuit frees the unlocking instrument when a fault is detected.

Abstract: A security device simulating a currency pack or the like to foil robbery includes a receiver unit for receiving a local carrier signal generated locally at the exits of the bank. The carrier signal includes information in a predetermined binary code and the security device includes logic elements producing a signal activating a tear gas charge or the like when a signal is received carrying information in the predetermined code.

Abstract: A security system for allowing selective access to a secured area generally comprises first and second three wing center shaft ganged revolving door structures, each partially surrounded by upright facing curved side walls disposed in spaced apart relationship to define a mid-zone. A digital combination lock at the first entryway provides initial access. Any two wings of the revolving doors have an angular span less than that traversed by each side panel to define a lockable detection chamber. A gas ionization explosives detector is coupled to the detection chamber. The mid-zone comprises metal and X-ray detectors and a hand geometry reader. The second revolving door has an entryway actuatable by a pass card reader. The second revolving door provides access to the secure region.In operation, an individual seeking access punches a combination lock releasing the first revolving door allowing the wings to rotate and then lock, enclosing a detection chamber in which the individual is confined.

Abstract: A composite security panel having at least two fibre optic elements contained within a block of material, the elements being arranged with portions emerging from the panel at three or more spaced locations. Translatory movement, rotation or tilting of the panel when assembled in a wall or housing causing translatory movement of an emergent portion of an element resulting in the interruption of a transmission line through the wall of housing. The elements may be firmly embedded within the panel, the fibre optic being carried on a strip of mateial, or the elements may be formed into a mesh which can be loosely housed between interconnectable sections of the panels.

Abstract: A portable depository container 10 for an automated teller machine (ATM) articles as, for example, magnetic credit cards captured by the ATM. With the container dismounted from the ATM, an entry slot 16 is locked against passage of articles therethrough by means of a bar 22. Upon the container being mounted in a receiving cradle 18 of the ATM, the bar 22 is moved to an unlocked position by means of key pins 168, 170 which engage and move rearwardly with a pair of slide members 42, 44. This movement of the member 42 brings about a rotational movement of a resettable indicator wheel 76 which carries a series of markings on its perimeter. The particular marking of the wheel 76 visible through an indicator window provides an indication of the number of times the bar 22 has been unlocked since resetting of the wheel, and can thereby indicate whether tampering with the container has taken place. A second embodiment for handling articles such as currency in envelopes utilizes a resettable indicator slide 208.

Abstract: The disclosure is of a pilfer-proof display unit particularly useful for security of small articles such as rings and like jewelry while permitting a potential customer free access to the handling of the article.

Abstract: An antishoplifting system for premises in which goods are sold and in which signal transmitters are affixed to the articles of goods. Each of the transmitters has a continuously effective first signal emitter which cooperates with a detector at the entrance or exit of the premises to signal removal of an article with the transmitter thereon. In addition, each transmitter comprises a self-contained second signal emitter, which requires no external energy source and is activatable upon removal of the transmitter from the goods to emit a signal. Receivers on the premises detect this signal and produce an output indicating the location of the source thereof.

Abstract: A monitoring system for detecting changes in the fluidic impedance of the boundary regions or volume of an enclosure, including detecting entry into, as well as certain movements within, a substantially sealed enclosure by means of synchronous detection of a modulated pressure signal within the enclosure. The air pressure within the enclosure is modulated at a predetermined amplitude and at a frequency which is sufficiently low to substantially avoid reverberation and wave interference effects, and means tuned to that frequency produce electrical signals indicative of the amplitude and phase, whereby entry into or exit from the enclosure, opening of a chamber within the enclosure, or blockage or unblockage of passageways within the enclosure vary the amplitude and/or phase of the modulated pressure, thereby causing an electrical signal to vary sufficiently to actuate an alarm.
