Abstract: A fire detector is connected to a loop transmission line connected to a receiver. When the loop transmission line is normal, a transmission unit is connected to the fire detector. When a disconnection failure occurs, a disconnection monitoring unit turns on switching circuits to connect the end of the loop transmission line to the transmission unit, and the receiver connects to the fire detector from both ends of the loop transmission line. An input/output switching booster is inserted and connected in the middle of the loop transmission line, and when the start side transmission line is disconnected and the switching circuits are turned on, the input/output is switched. Accordingly, the input/output switching booster amplifies the down signal input from the terminal side transmission line and outputs it to the start side transmission line and at the same time amplifies the up signal input from the start side transmission line.

Abstract: A method for operating a process plant, in which a number of alarm notifications for indicating non-compliant operating events of the process plant are generated at process level. Alarm notifications which can be generated during the operation of the process plant are defined. At least a number of the generatable alarm notifications are assigned, in each case at least a first value or a second value as a dependency value. A current process state of the process plant is determined and depending on the determined process state, those alarm notifications to which the first value was assigned as a dependency value are not indicated.

The or each fire alarm module comprises a message store (22), means for interfacing with an amplifier (6) of the voice alarm system, means for interfacing with the fire alarm loop (1) and means for interpreting signals from the loop (1) and for selecting an appropriate message for transmission from the message store (22).

Abstract: An improvement to a self powered fire alarm consisting of an improved housing sealing method that improves the reliability of the alarm by preventing insect infiltration. Additional improvements consist of an improved alarm activated notification, along with the incorporation of a wind down prevention detail and a retainer for the winding key. Each of these improvements provides additional benefit to the user.

Abstract: A emergency sign emits a non-electrical light and sounds a non-electrical alarm when an elevated level of heat is sensed, such heat from a fire, to provide a combined light and a sound alert signals. The light results from the mixing of a chemical compound having chemiluminescent properties. The light illuminates indicia located on the face plate of the sign. The alarm is sounded by releasing compressed gas from a cartridge and directing the released gas through a whistle.

Abstract: A golfer's watch (1) includes an analog counter (2) for the strokes taken on a hole, and a counter (3) of the total number of strokes of the game.

Abstract: A fire detection port installed in doors of occupied structures provides visible and audible signals on one side of a door in the event of fire on the other side of the door.

Abstract: A security dye pack disguised as a bundle of currency for deterring robberies includes a housing formed from a stack of currency bills sewn together and having a hallow chamber formed therein. A substrate disposed within the chamber has a flexible central region through which electrical conductors extend for making electrical interconnections between opposing ends of the substrate. Electrical components are mounted on both sides of the flexible central region to generate an actuating signal upon detecting removal of the security dye pack from the protected premises. Canisters containing dye or other active chemicals are secured at opposing ends of the substrate to emit dyed or other active chemicals in opposing directions when expended. The flexible central region of the substrate allows the security dye pack to be bent into a U-shape. Batteries are arranged in a side-by-side relationship in an elongated narrow case to facilitate bending of the security dye pack.

In one embodiment, the present invention is a remote signal-actuating device for attachment to articles which includes a fluid-containing member which releases detection fluid in response to a predetermined force. In a second embodiment, an electronic security device includes such a fluid-containing member, and, in a third embodiment, a security device for physically restraining an article includes such a fluid-containing member. The detection fluid may be a gas, a liquid or a mixture of these and it may be a coloring agent, an odor containing fluid, a flourescent or phosphorescent dye, a radioactive material or the like.

Abstract: A portable, self-contained combination smoke and burglar alarm includes a smoke sensor and a tester switch both capable of energizing of an audible warning device, all contained in a housing adapted for mounting on an interior room surface such as on a wall or ceiling above a door or window. A releasably inserted locking pin retains a spring-biased plunger mounted above a pressure actuable tester switch accessible externally of the housing to maintain the plunger in its cocked condition. A line attached to the releasable locking pin also attaches to an adjacent door or window such that opening of the door or window increases tension on the line which effectively removes the locking pin and releases the plunger to strike the tester button and actuate the alarm.

Abstract: The invention is an improved burglar alarm for doors and windows or other similar openings in an enclosure to be protected against secretive entry. The invention consists of a series or plurality of bell-like devices which are automatically dumped or knocked to the floor when entry is made, thus creating an alarm noise. The alarm is operable on doors or windows that swing or slide, or which open inwardly or outwardly. The alarm is of simple construction and easy to install, consisting of a plurality of bell-like elements, a supporting rod, mounting apparatus for the supporting rod, and a wiper member for certain mounting positions.

Abstract: A heat alarm for releasing a strong readily noticeable odor when subjected to heat above a preselected level. A glass container having an elongated breakable neck portion is filled with an odoriferous fluid. When the neck portion is broken, the fluid can escape from the container. The fluid upon contact with the atmosphere creates a strong odor the presence of which is immediately apparent to all persons within the surrounding area. A heat reactive member that bends upon being subjected to heat above a preselected level is arranged around the neck portion of the container. When this heat reactive member is subjected to heat above the preselected level, the member bends and breaks the neck portion of the container thereby enabling the fluid to escape.

Abstract: A gong or bell attached to a door such that when a thief breaks open the door, a ball or like object having a rod extending therethrough and resting on a ledge which projects from the top of a frame for the door, falls along the rod as the ball or like object is pushed with the door out of a slot in the ledge and rings the gong or bell by striking it and a spring which prevents muffling of the sound.

Abstract: A mechanism for activating a plurality of flashlamps in a flashlamp article (e.g., MAGICUBE) in response to external actuation (e.g., the opening or closing of a door) thereof. To prevent accidental actuation, the mechanism includes a safety device in the form of an elongated pin which inserts within a pair of aligned openings within the mechanism to positively engage and retain the mechanism's movable activator. In one embodiment, the pin is also attached via a cord to the mechanism's spherical ball engagement member which causes movement of the activator.

Abstract: The passage-way between a freon cylinder and a freon-powered horn is plugged by a eutectic metal plug. When sufficient heat loosens the plug, the horn is activated. A switch in the passageway senses the back pressure from the freon gas flow and activates a remote electrical indicator which can be used to determine which of a plurality of horns has been activated.
