Abstract: The disclosure relates to a battery exercising device configured to discharge and charge a rechargeable battery. The battery exercising device is configured to receive electrical power from a power source and periodically transfer this power into a rechargeable battery connected to the battery exercising device. A battery assessment may be performed on the rechargeable battery to determine whether to charge the battery after the battery assessment. The rechargeable battery may be desulfated during the battery assessment in an effort to restore or increase the cranking power and/or the charge timing of the rechargeable battery. A solar panel may be provided as the power source and may be used in conjunction with a bank battery to store collected solar power until needed to recharge the battery.

Abstract: The disclosure relates to a battery exercising device configured to discharge and charge a rechargeable battery, such as a lead-acid battery, after a set amount of time has elapsed. The battery exercising device is configured to receive electrical power from a power source and periodically transfer this power into a battery connected to the battery exercising device. After a period has elapsed, for example two weeks, the device applies a discharging load to the connected battery to drain the battery to a predetermined discharge level. Thereafter, the device charges the connected battery to a predetermined charge level. Once charged to the predetermined charge level, the device again waits the set period of time and repeats the discharge/recharge sequence.

Abstract: A method of controlling a motorized device comprises the steps of providing a motorized device, receiving a code, checking that code, and changing the operational state of a portion of the motorized device in response to the code in certain circumstances. In one embodiment, the motorized device comprises a drive system, an activation mechanism, and a safety circuit that is in communication with the activation mechanism and at least a portion of the drive system. After receiving an unlocking code from the activation mechanism, the next step is to determine if the received unlocking code corresponds to a predetermined unlocking code. Subsequently, if the received unlocking code corresponds to the predetermined unlocking code, then the safety circuit is transitioned from a locked state to a normal operation state. Additional codes and corresponding operational states may also be incorporated into other embodiments of the method.

Abstract: A safety system comprises an activation mechanism, a safety circuit, and a drive system in communication with each other. In one embodiment, the activation mechanism produces an activation signal in response to an actuation of the activation mechanism. The safety circuit operates in either a locked state or a normal operation state. In this embodiment, the safety circuit is programmed to prevent the activation signal from being communicated to the drive system when the safety circuit is operating in the locked state and to allow the activation signal to be communicated to the drive system when the safety circuit is operating in the normal operation state. The safety circuit is programmed to transition from the locked state to the normal operation state in response to receiving both an unlocking code and a follow-up signal that is received by the safety circuit within a predetermined amount of time.

Abstract: A coal sampling device is provided for the efficient extraction of a core sample of coal from a container, such as a coal truck or railroad hopper car, and crushing of the extracted coal sample into particles useful for laboratory analysis. Uncrushed pieces of extracted coal are transported to a separating device that allows most of these extracted coal pieces to fall back into the container through several open windows. The separating device also includes an additional window through which extracted coal pieces fall into a crushing device, where the coal pieces are crushed to pebble-sized pieces. The crushed coal pieces are allowed to fall out of the bottom of the coal crushing device, and a portion of the crushed pieces are collected by a sample collecting receptacle, which accumulates portions of the crushed coal throughout the core extraction process so that a true representative sample of the total extracted core is collected.

Abstract: A coal haulage apparatus is provided for use in moving coal fragments within the horizontal shafts of a coal mine on a belt conveyor that runs longitudinally along the apparatus. The apparatus is an assembly of multiple, like sections that each have a pair of longitudinal rails and cross members which join the rails together in a parallel, spaced-apart relationship, of which the rails are designed to receive the bottom portion of V-grooved wheels of a dolly that can move longitudinally along the top of each section of the coal haulage apparatus. The longitudinal rails essentially act as the frame that supports the vertical weight of the dolly which rolls along the top of each section of the coal haulage apparatus, and a separate vertical support frame is not required. The rails are made of square tubing that uses a smaller mating, connecting tube to join rails from one section to another adjacent section.
