International Classification:

H01C 7/10

US Classification:

338 20, 338 21, 361127

Abstract:

An MOV element is physically and electrically connected to a heat sensitive material which changes from a low impedance path to a high impedance path, such as a spark gap, when the temperature of the MOV element rises to a temperature below that at which the MOV will enter into its thermal runaway state. More specifically, the heat sensitive material is located on a surface of the MOV and is electrically connected in series with the MOV. In operation, as the MOV gets hot, it heats the heat sensitive material. As the heat sensitive material gets hot, it starts to separate from the surface of the MOV to form a spark gap which is electrically connected in series with the MOV element to help dissipate excessive voltage. The heat sensitive material on the surface of the MOV element can be a coating of epoxy which cracks and/or breaks away, at least partially from the surface of the MOV element during the occurrence of a high voltage transient surge, or it can be a solder that sputters to form an arc path during the occurrence of a high voltage transient surge. In operation, when a GFCI is subjected to a high voltage transient surge above a certain magnitude, the heat sensitive material forms a spark gap which is in series with the MOV and prevents the GFCI from going into its destructive thermal runaway condition.

Appl. No.:

09/940138

Inventors:

John Power - Garland TX, US

International Classification:

B65G051/06

US Classification:

406/190000

Abstract:

A simple but effective concept of using nylon, polypropylene or other flexible filament as brush to create ring seals for pneumatic transfer carriers, thus affecting a virtually air tight seal as well as superior durability due to the low coefficient of friction between the plastic brush filament and the conduit through which it passes.

Assignee:

Swingline, Inc. - Long Island City NY

International Classification:

H01H 4732

US Classification:

3171485B

Abstract:

An electrically operated stapling device is disclosed. Staples are driven into the article to be stapled by a simple driver blade which is powered by a current actuated solenoid. In the preferred embodiment, the solenoid is provided with a plurality of pulses which are derived from alternate half-cycles of an AC power source which powers the stapling device. The circuit produces two pulses by defining a window in each of the successive output cycles of the power source. The current then initiates the generation of an enabling signal which lasts for a predetermined period of time which begins during the window. During this period of time, alternate half-cycles of the power source are coupled to the solenoid, thereby causing the driver blade to drive the staple into the article to be stapled.
