Abstract: A weather-resistant cover for an electrical connection box is constructed of a resilient elastomeric material. In a preferred embodiment of the invention, the elastomeric cover is immovably sandwiched between an outlet face plate and an electrical receptacle and the box to which the receptacle is secured. The cover prevents moisture and airborne particles from getting into the connection box. Self-closing slots cut into the elastomeric cover are in alignment with the prong opening in the electrical receptacle. An electric plug may be plugged into the receptacle by inserting the plug's prongs through the slots in the cover and into the receptacle. When an electric appliance is plugged into the device, a seal is formed between the face of the plug and the elastomeric cover. When the plug is removed, the slots in the cover automatically close due to the elastic memory of the resilient material of which the cover is made.

Abstract: Standing planar compression waves are used to control the spacing and alignment of previously randomly distributed and randomly oriented loose fibrous elements in a fluid medium. Standing planar compression waves are established within the medium by a magnetostrictive or piezoelectric transducer. The fibrous elements gravitate to the nodes of the standing waves and align themselves parallel to the vibrating surface of the transducer. The composite material may be solidified by cooling (or other process), which freezes the fibrous elements in an aligned array, thereby effecting the directional dependency of various structural properties of the composite material (including compression strength, tensile strength, and modulus of elasticity).

Abstract: Compressed air-driven electrical generator supplies electric current to resistance heating element on demand in a baseboard heating system. A thermostat in communication with an air valve actuator, allows compressed air to flow from an air holding tank to an air motor which drives the electric generator whenever the temperature in the control space drops below a pre-selected temperature. An electrical relay switch in series with the electric generator and an electrical resistance heating element opens the electrical circuit between the electric generator and the heating element whenever the temperature sensed by the thermostat drops below the pre-selected temperature.
