Abstract: A portable sensor includes (i) a housing; (ii) one or more sensing devices, such as a video camera and/or a gas sensor (iii) a transmitter, electrically coupled to the sensing device(s) for transmitting a signal generated by the sensing devices; and (iv) a power source electrically coupled to, and for supplying electrical power to, the sensing devices, and the transmitter. The sensor is particularly useful for surveillance, inspections, medical emergencies and a variety of different settings in which remote transmission of inspected images is desired.

Abstract: A continuously advancing workpiece (e.g., a steel rod) is treated prior to size reduction by drawing. The rod is preheated and then a liquid (such as a borax solution) is applied to the surface of the rod. The preheating of the rod provides sufficient residual heat within the rod to rapidly and evenly dry the liquid such that the rod is provided with a thick and uniform coating. Also disclosed is a system for conditioning the coating liquid.

Abstract: A method of mixing silicone rubber polymers with fillers and/or other additives without employing a kneading type action wherein the ingredients to be mixed are impacted with a high speed mixing blade for a first period of time in which the blade is operated at a tip speed of about 150 feet per second, until the ingredients are reduced to relatively small uniform particles and then operating the mixer blades at a speed of about 300 feet per second until sufficient viscosity of the material is reached.
