Abstract: Organopolysiloxane fluids, thiofunctional polysiloxane fluids, or blends of organopolysiloxane fluids and thiofunctional polysiloxane fluids are stabilized against degradation in the presence of kaolin clays at elevated temperatures by adding an epoxy containing compound.

Abstract: A device for the practice of the running-jumping-striking volleyball maneuver known as spiking including an elevated volleyball tethered below an essentially horizontal backstop by a flexible funicular rod. The backstop and flexible funicular rod serve rapidly to damp the kinetic energy imparted by spiking. The flexible funicular rod may also serve to impart a realistic feel to the person using the device to practice spiking. Elevated support for the volleyball is provided by an adjustable arm clamped to a volleyball net's end post or, alternatively, by an arm detachably mounted to the hoop of a basketball net. The device may be assembled, erected, and used by one person.
