Abstract: A computing machine accesses a directed graph representing one or more sequences of actions. The directed graph comprises nodes and edges between the nodes. Each node is either a beginning node, an intermediate node, or an end node. Each intermediate is downstream from at least one beginning node and upstream from at least one end node. Each beginning node in at least a subset of the beginning nodes has an explainability value vector. The computing machine computes, for each first node from among a plurality of first nodes that are intermediate nodes or end nodes, a provenance value representing dependency of an explainability value vector of the first node on the one or more nodes upstream from the first node. The computing machine computes, for each first node, the explainability value vector. The computing machine provides a graphical output representing at least an explainability value vector of an end node.

Abstract: An air braking unit for use in an air braking system. The air braking unit is arranged to be positioned, in use, at a vehicle wheel, and comprises an inlet for receiving, in use, compressed air from a central source. At least one first valve is arranged to selectively allow compressed air from the inlet to enter a wheel brake chamber in use. At least one second valve is arranged to selectively allow air from the brake chamber to be released via an outlet to the atmosphere in use and control means controls the first and second valves to operate to selectively control the air pressure in the brake chamber in use.

Abstract: A trash container that allows the user to compress trash when the user manually pushes the top cover down. When an indoor trash container seems full, people would normally press the garbage down into the container using their hands in order to create more room inside the container. That is unsanitary. Our invention is a trash container that allows the user to compress trash when the user manually pushes the top cover down. A user's hands don't touch the trash.

Abstract: An electrical control network is laid over one or more vehicle dynamics control and/or ride control systems of a heavy vehicle, which control network controls actuation of components thereof. The invention offers many advantages including reduction of components, simplified design, unified communication for numerous different types of system components, simplified resolution of conflicts between competing control strategies, expandability to additional vehicle systems, and flexibility to upgrade for new, improved vehicle control schemes.

Abstract: A brake actuator including a chamber in which is provided a movable pressure responsive element which divides the chamber into first and second compartments, the brake actuator also including a valve assembly with an inlet which is connected to a source of pressurised fluid, an outlet which is connected to a volume within the brake actuator not including the second compartment, and an exhaust port through which fluid from the volume may be released, wherein the exhaust port of the valve assembly is connected to the second compartment.

Abstract: A modular brake system, such as is used in ABS and EBS that allows for exchangeability of the various brake parts including the modulator, actuator and brake assembly; the modulator being detachably connectable and located adjacent to or directly on the actuator. An ECU further controls the brake system and is provided with redundant control line inputs. The control line inputs, both primary and back-up, are provided as electrical lines extending from the control device to the controller.

Abstract: A method for protecting high temperature stainless steel from coking and corrosion at elevated temperatures in corrosive environments, such as during ethylene production, by coating the stainless steel with an overlay coating of MCrAlX in which M is nickel, cobalt, iron or a mixture thereof and X is yttrium, hafnium, zirconium, lanthanum or combination thereof. The overlay coating and stainless steel substrate are heat-treated to metallurgically bond the overlay coating to the substrate and to form a multiphased microstructure. The overlay coating preferably is aluminized by depositing a layer of aluminum thereon and subjecting the resulting coating to oxidation to form an alumina surface layer. An intermediary aluminum-containing diffusion coating may be deposited directly onto the stainless steel substrate prior to deposition of the overlay coating to form a protective interlayer between the stainless steel substrate and overlay coating.

Abstract: Apparatus is disclosed for synthesizing ammonia from an ammonia feed gas passing to an ammonia synthesis converter from a heat exchanger. The synthesis converter is close coupled through a channel to a heat exchanger and a conduit extends through the channel and is adapted to be connected to the tube side of the heat exchanger.

Abstract: Apparatus for synthesizing ammonia from an ammonia feed gas passing to an ammonia synthesis converter from a horizontally disposed heat exchanger. The synthesis converter comprising a shell and catalyst holder positioned within and spaced slightly from the shell to provide an annular passageway therebetween, is close coupled through a channel to a heat exchanger and a conduit extends through the channel and is adapted to be connected to the tube side of the heat exchanger.
