Abstract: An improved solid expellant plasma generator has been developed. The plasma generator includes a support housing, an electrode rod located in the central portion of the housing, and a mass of solid expellant material that surrounds the electrode rod within the support housing. The electrode rod and the solid expellant material are made of separate materials that are selected so that the electrode and the solid expellant material decompose at the same rate when the plasma generator is ignited. This maintains a point of discharge of the plasma at the interface between the electrode and the solid expellant material.

Abstract: My invention attaches to trucks with snowplows. When the truck owner takes the snowplow off of the vehicle, my brush guard clips on to the truck side push plates remaining on the truck after the snowplow has been removed. To use the snowplow again, pull the pins on the brush guard slide it off and drive up to the snowplow and reattach snowplow without any tools required. This process consists of two easy steps. Slide the brush guard onto the snowplow push plates until the holes line up. Twist and pull the spring loaded pins to (1) engage pins. To remove brush guard pull and twist pins ¼ turn until retaining key holds (10) pins open and slide brush guard off.

Abstract: A SLIC includes in separate and distinct contacts for the output of a tip and ring line driver and their feedback resistors to the balancing resistor of the appropriate tip and ring line. Thus, a Kelvin contact arrangement is produced providing a compensation for the contact resistance of a single connection.
