Abstract: The present electrical resistor package has a naked electrical resistor element which is designed to provide quantitative resistance to electrical current flow, said element is initially encapsulated in a flexible coating, such as silicone wax, which absorbs stresses and is secondarily encapsulated around said flexible coating, in a cushion type moisture barrier coating, such as silicone rubber, to keep moisture away from said element and finally is encapsulated around said moisture barrier coating by a hard protective coating, such as epoxy, to protect the nak ed element from physical and environmental damage.

Abstract: A mouse trap includes first and second telescopically related housing members which are movable between extended and retracted positions. A door opening is provided in one of the housing members which provides access to the interior of the housing when the housing is in its extended position but which is blocked by the other housing member when the housing is in its retracted position. A spring biased striker arm is mounted within the housing members and is adapted to be held in a cocked position by a trigger arm when the housing members are extended. Actuation of the trigger arm causes the striker arm to deliver a lethal blow to a mouse who has released the trigger arm and also causes the housing members to be simultaneously moved to their retracted position.

Abstract: The present device is a high reliability resistor comprising a sheet of metal foil secured to the flat side of a substrate and with the opposite side of the substrate formed to dissipate heat into the ambient thus enabling the present resistor to have an improved temperature coefficient of resistance (TCR) and further enabling the resistor to function satisfactorily in a high wattage mode.
