Abstract: The techniques described herein may provide for more efficient power management of equipment based on weather conditions. For instance, weather measurements (e.g., or weather forecasts based on weather measurements) may be used to determine whether or not to initiate a power disconnect procedure. When some weather condition (e.g., wind, temperature, rain, humidity, etc.) exceeds a threshold, a power disconnect procedure may be initiated such that a power source of certain equipment may be disconnected from a power distribution system. In some examples, an environmental monitor may send environmental measurements or conditions to a programmable processor. In instances where the programmable processor determines that some environmental threshold or condition has been met, the programmable processor may send a disconnect signal (e.g., a disconnect power signal) to a power disconnect device. The power disconnect device may thus disconnect the power distribution system from the power source.

Abstract: A drive mechanism for a tilting-pan filter assembly comprises an annular carrier for supporting a plurality of filter pans for motion along a circular transport path. The carrier is moved along the circular path by drive componentry including a plurality of individual hydraulic motors having pinions meshing with a ring gear on the carrier at respective equispaced drive points. The hydraulic motors are driven by a single pump which supplies a hydraulic fluid under variable pressure and variable flow rate. The hydraulic motors are connected in parallel to one another and to the pump in a closed loop hydraulic circuit. The pump may be driven by an electric motor which absorbs braking energy.

Abstract: A material is provided which has a positive thermal coefficient of resistance. The material is made of nickel particles sintered in a plastic matrix. The material is suitable in internal elements of electrochemical cells.

Abstract: This disclosure pertains to a signalling device which is magnetically temporarily secured to an exterior surface of a motor vehicle. When in use, two end elements are disposed in parallel spaced apart relationship by a plurality of interconnected linkage arms forming a series of parallelograms. When expanded, the apparatus forms a display area having a substantially rectangular shape bounded on two sides by the end elements. The display surfaces of the end elements and the linkage arms are adapted with a reflective material permitting the operator of an oncoming vehicle to readily discern the presence of a disabled vehicle. The linkage arms are collapsible, thereby permitting easy storage within the motor vehicle when not in use. Carrying and size adjusting handles and a locking mechanism for locking the device in a collapsed position are provided.
