Abstract: An impact-dispersing undergarment is provided. The impact-dispersing undergarment includes a wearable substrate, such as a flexible fabric, adapted to cover at least a portion of an individual's body. The undergarment includes at least one resilient, impact-dispersing gel packet coupled to the wearable substrate. The gel packets are selectively coupled to the wearable substrate and adapted for use underneath conventional protective padding. A method for protecting an individual during impact by employing the impact-dispersing undergarment under conventional protective padding is also provided.

Abstract: An axial lead bridge rectifier includes four rectifying diode chips and a large pulse suppressor chip all disposed between the paddle sections of two coaxial leads. Two of the diodes are solder-connected in series between the two paddle sections, with their anodes solder-connected to a first cantilever conductive strip, the opposite end of which is soldered to one face of the pulse suppressor chip. The opposite face of the pulse suppressor chip is soldered connected to a second metal strip which extends in cantilever fashion from a solder connection to the cathodes of the other two diodes, which are also solder connected to the first and second paddle sections, respectively. The portion of the assembly including the paddle sections of the two axial leads and the rectifier bridge circuit and pulse suppressor thereof are encapsulated in suitable glass, plastic or ceramic material out of which the two axial leads extend.

Abstract: A mandrel for forming an annular groove in the bell of a plastic pipe which comprises a plurality of identically formed segments. The segments are radially urged identically from an initial position which is inwardly of the bell to an expanded position wherein the segments cooperate and interact to form an expanded ring of diameter greater than the pipe bell to thereby impress a circular groove therein. An actuating shaft rotatively reciprocates in unison a pair of cam plates, which cam plates are characterized by a plurality of arcuately curved guide slots formed therein. The segments include follower pairs which respectively ride within the guide slots to urge the segments from their initial positions to their expanded positions and back upon rotative reciprocation of the cam plates.
