Abstract: A vacuum sander includes a head assembly. A handle attachment is rotatable coupled to a drive to allow selective rotation of the handle attachment relative to the drive and a debris shroud about a first axis. The drive is rotatable relative to the debris shroud to allow selective rotation of the drive and the handle attachment relative to the debris shroud about a second axis different from the first axis. The drive is rotatably coupled to a forked handle attachment between two prongs thereof. The drive is configured to couple to a sanding implement and to selectively drive rotation of the sanding implement about an axis.

Abstract: An intelligent locomotive brake control system which selects and optimizes use of dynamic, independent, and automatic brakes on the locomotive to assure intended brake power, to minimize in-train forces, minimize brake component wear, and to automate standard train brake protocol. The system may be programmed to alter an automatic brake application commanded by a train driver to omit or reduce the amount of the automatic brake application in favor of a dynamic brake application, and independent brake application, or combination thereof.

Abstract: Some embodiments provide a product storage racking system, comprising: a frame comprising frame beams secured together with support surfaces aligned along a first plane; feet posts fixed to the frame beams; feet cooperated with the feet posts, wherein each of the feet is configured to stackably cooperate with a post of a set of posts that are cooperated with another product storage racking system enabling stacking; at least two rack support systems each secured with the frame and configured to support the weight of the product storage racking system and products stored on the product storage racking system independent of the three or more feet.

Abstract: A locomotive air brake control system that responds to penalty braking requests from external systems by applying a varying amount of train brake level based on monitored and calculated parameters in order to enforce a defined train condition. The system may include a minimum acceptable train braking, a condition to be achieved to prevent further application of train brakes, and a maximum train brake level to be applied in response to the request. Alternatively, the system may apply braking in stepped levels according defined thresholds for a train behavior variable of interest such as speed or deceleration. The system may be configured to incrementally apply and release train brakes during the adaptive penalty, and may also adjust the level of braking according to calculated braking capacity of the train.

Abstract: A system and method for automatically calibrating the flow measurement device of a locomotive air brake control system. The air brake control computer controls activates a magnet valve to create a predetermined flow from the brake pipe through an orifice to exhaust, thereby creating a reference flow value to enable the calibration of the flow measurement device. The system reduces the likelihood of human error and variability by automating the steps necessary for flow measurement calibration under computer control.

Abstract: The dual vent valve includes a housing having brake pipe, emergency input and exhaust ports, and first and second valves. The emergency output port is fluidly connected to the emergency input port. The first valve selectively connects the brake pipe port to the exhaust port by opening the first valve in response to an emergency signal on the brake pipe port. The second valve selectively connects the brake pipe port to the exhaust port by opening the second valve in response to an emergency signal on the emergency input port.

Abstract: A manifold includes first and second plates secured together at an inner face of each plate. A plurality of chambers and passages are in the inner faces of the plates and at least one port on an outer face of each plate connected to one of the chambers and passages. A crossover element in the inner face of the first plate separates a chamber or passage in the first plate from a chamber or passage in the second plate in the crossover area where the chambers or passages cross.
