A cutoff tool characterized by the fact that the cutting portion thereof is provided with a localized cutting area that includes a relatively high degree of compound clearance angles provided in a minimal amount of space for increasing the cutoff efficiency and the tool life, while permitting simplified grinding withou...
A rapid cutoff device includes a thyristor DC switch, a switch and a capacitor. An operation method includes: connecting the thyristor DC switch between a first DC circuit and a second DC circuit; serially connecting the switch and the capacitor which further parallel connects the first DC circuit; when the thyristor D...
A plurality of series-connected interrupters are connected in series and are mounted in a low-pressure tank. Pairs of the interrupters are mounted on a high-pressure tank filled with SF6 gas. Each individual interrupter contains its own blast valve, adjacent cooperating contacts and disposed radially interiorly of a ma...
A fuel cutoff valve is provided with a casing that forms a valve chamber that is connected to a connection conduit, a float mechanism that is housed so as to be able to rise and fall in the valve chamber, and a spring that supports the float mechanism. The float mechanism is structured through an assembly of a first fl...
PROBLEM TO BE SOLVED: To control an operation of a fuel injection valve heater from a view point of maintaining a heating degree of a fuel injection valve at a proper value or less. SOLUTION: A threshold is set to the heating degree of the fuel injection valve and when the heating degree exceeds the threshold, the oper...
Systems and methods provide an alternative high voltage cutoff technique for disconnecting a high voltage battery from an electrical network of a vehicle in the event of a fault condition. Embodiments include a vehicle system comprising an electrical bus and a battery module coupled to the electrical bus via a contacto...
An electrical panelboard enclosure includes an enclosure housing with an interior equipment chamber accessible by way of a service entrance door. A service panel is configured to receive power from a main power source. A main power breaker has a main power breaker toggle switch and is positionable between a power-on st...
A cutoff frequency adjusting method adjusts a cutoff frequency of a GmC filter circuit which has a capacitor and an Operational Transconductance Amplifier (OTA) circuit with a controllable Gm value. A Gm value of the OTA circuit is detected based on a voltage of the capacitor which is charged by an output of the OTA ci...
So as to make the best use of the modularity provided by a double-casing multipolar circuit breaker (100), a novel architecture is provided. A potion of the outer housing (48) of the cutoff apparatus (100) is formed directly during the assembly of the cutoff device (600) by means of juxtaposing and rigidly connecting t...
A lawnmower engine cutoff system interrupts the electrical flow to the ignition system of an engine when a predetermined weight of clippings is contained within the catch bag for grass clippings. Mechanical movement is generated by the weight of the grass clippings contained in the catch bag. This movement is then sent...
A system for detecting a target substance within a class of explosives and narcotics containing quadrupolar nuclei through the use of nuclear quadrupole resonance (NQR). The system applies an RF signal to a coil to excite the substance under test. If the target material is present, an NQR signal will be picked up by th...
A device for sticking adhesive tape to thin articles, such as semiconductor wafers, and trimming excess portions of said tape from the thin articles. A plurality of sticking rollers apply adhesive tape from a roll to each thin article, the tape having an adhesive side oriented towards an upper surface of the article an...
A vacuum cleaner having a thermal cutoff assembly. The assembly includes a temperature sensor disposed proximate to a motor of the vacuum cleaner. When the temperature sensor reaches a predetermined temperature, a switching element in the assembly disconnects power shutting off the vacuum cleaner. The vacuum cleaner ca...
A surgical trocar includes an operative sleeve adapted for disposition across a tissue barrier and an obturator removably disposed in the sleeve. An obturator includes a cutting element which is operable to cut the tissue. The obturator and the operative sleeve can be advanced through the cut tissue and the obturator r...
A secondary detection circuit for a paper security validating device which device scanned a portion of one surface of the paper security. The secondary detection circuit compares the level of reflection of light from the reverse side of the security with a known level and, if the reflected level falls below a first val...
A rare earth magnet block is cutoff machined into pieces by rotating a plurality of cutoff abrasive blades. Improvements are made by starting the machining operation from the upper surface of the magnet block downward, interrupting the machining operation, turning the magnet block upside down, placing the magnet block ...
