A computer program, database and method for the detection of fissile or radioactive material or radiation shielding material in a container works with detection devices brought into proximity to containers so that the presence of fissile or radioactive material, or shielding materials to conceal the presence of such fissile or radioactive materials, may be detected. A comparison may then be made of the output of the detector to a threshold to determine subsequent action regarding the shipping co...

There is described an air freshener dispenser, in particular of the type fittable to vehicle air inlets, which has an indicator circuit for indicating an incoming call on a cellular telephone in the vicinity of the air freshener dispenser.

An apparatus for enhancing sanitation in a kitchen equipped with an oil/grease separator includes a barrier made of two vertical portions connected by a horizontal portion to bound a volume between the oil/grease separator and a kitchen wall and prevent the ingress of debris. The vertical portions have lower flanges for affixation to a floor, edge flanges for affixation to the separator and the wall, and horizontal ears at upper ends. The horizontal portion has downward edge flanges for affixati...

An oxygen-depolarized cathode for aqueous hydrochloric acid electrolysis membrane cells is described, the cathode being in contact with the membrane and capable of preventing the release of hydrogen into oxygen even at the highest current densities. Hydrochloric acid may also be of technical grade with a concentration limited to 15%, whereas the operating temperature must not exceed 60.degree. C. The cathode contains a mixture of rhodium sulphide and a metal of the platinum group applied in a si...

A method of operating a computer for smoke and flame detection comprising the steps of: receiving digitised images of the region to be monitored; comparing pixels of one of said images with pixels of another said image according to two predetermined procedures to produce a flame present decision and a smoke present decision; and providing a fire detected signal according to said smoke present and flame present decisions.

A contactless ambient condition detection system includes at least one base connectable to a power and signal transmitting cable and a compatible detector. The detector removably engages the base. Electrical energy, from the cable is wirelessly coupled to the detector via the base. The detector is in wireless bidirectional communication with the base. Alarm indicating signals, generated remotely, can be wirelessly coupled, from the cable via the base, to the detector. Locally generated alarms ca...

A device with a multi-function test feature for assessing or directing multiple sensor functions is provided for monitoring and interrogating air flow through Heating/Ventilation/Air-conditioning (HVAC)-type ducts for changes to ambient conditions such as smoke, heat, gas, and/or relative humidity.

The invention relates to a flame-monitoring device in which an a.c. input voltage (U1) is limited to a voltage limit (U2) by means of a voltage limiter (4). Said voltage limit (U2) is applied to a flame sensing device (7) which operates by means of the rectifying effect of a flame, and through which a current (i) flows, especially when a flame (6) is present. An asymmetric voltage limit (U2) can be defined by said voltage limiter (4), said limit being then applied to the sensing device (7).

A die-casting device at least includes a housing having a seat, a lower mold mechanism at the seat, an oil-pressured injection mechanism joined with a lower section of the lower mold mechanism, and a corresponding upper mold mechanism disposed at an upper section of the housing and driven by an oil-pressured mechanism for up-and-down movements; wherein, the lower mold mechanism is devised as a structure with an outwardly inclined angle. Thus, when adding a metal liquid to the die-casting device,...

Provided is a nuclear radiation monitor which has a surface on which are located separate, visible indicia, such as LEDs or an LCD array, with the indicia being distributed around an imaginary closed loop, preferably of circular configuration. The monitor includes a radiation-sensitive apparatus, including a radiation sensor, and the apparatus is adapted to create a discharge every time a particle or pulse of radiation strikes the sensor window with sufficient intensity. The device incorporates ...
