摘要： Apparatus, devices, assemblies, systems and methods of using w spring clips over spikes for holding railroad tie spikes down to wood and concrete railroad ties and hold the spike heads to the rails. A first embodiment can use rail tie plates with box holders for holding end portions of a w shaped spring steel clip to press against cap heads of railroad tie spikes. A second embodiment can use a rail tie plates with vertical supports for horizontal bars over heads of railroad tie spikes. A third embodiment can use rail tie plates with vertical studs and upper threaded ends with flat plates attached by nuts over heads of rail road tie spikes, and with cotter pins locking the nuts in place. Additional embodiments include metal structures fastened, welded and/or forged to tie plates for allowing w shaped spring clips with mid portions that hold down heads on spikes to prevent the spikes from coming out. Additional embodiments can use concave side C-clips, convex side C-clips, double hook C-clips in flat plate and fire form, G-Clips and W-Clips with notches on leg ends. The embodiments can be used with auxiliary plates having welded bars over notch openings to hold down both heads of stakes and footer edges of rails.

摘要： A vehicle exit assist apparatus with improved security and power consumption includes an exit restriction part including a warning and/or door opening restriction when an occupant's exit action is detected and an obstacle around a self-vehicle is detected by an obstacle detection part. The obstacle detection part and the exit restriction part are started when the exit action is detected in a situation where the obstacle detection part and/or the exit restriction part are not working. The obstacle detection part may transmit a signal corresponding to its operating state after starting-up and the exit restriction part may be forced to perform the exit restriction action when the obstacle detection part is not operating normally based on the signal. It may be configured to cancel the exit restriction action when such a compulsory exit restriction action is being continuously performed for a period longer than a predetermined period.

摘要： An example fluid manifold, for a fracturing system, includes one or more spool sections and a flow passage at least partially defined by the spool sections that extends along a longitudinal axis. In addition, the manifold includes a first flow altering assembly positioned along the flow passage and including a diverter surface positioned to divert fluid radially away from the axis. Further, the manifold includes a second flow altering assembly positioned along the flow passage and spaced from the first flow altering assembly. The second flow altering assembly includes an annular flange and a flow altering tube extending axially from the annular flange such that the annular flange and the flow altering tube define an annular cavity that extends radially between the flow altering tube and an inner wall of the flow passage and that extends axially along the flow altering tube to the annular flange.

摘要： To control hydrostatic backpressure of disposal wells connected to a disposal plant surface network, density of water to be injected from a water disposal plant system into disposal wells formed in a subterranean zone, a density of a hydrostatic backpressure-modifying additive to modify a density of the water, a target total injection flow rate of the water, and a vertical depth of a portion of the subterranean zone through which the water is to be injected are identified. Injected water flow rate upstream of an injection point into the multiple disposal wells, wellhead injection pressure needed to achieve the target total injection flow rate and a total injection rate are periodically received. Based on these parameters, dosage rate of the additive to maintain the target total injection flow rate is periodically determined. An additive quantity is injected into the water and periodically modified based on the periodically determined dosage rate.

摘要： Aqueous well treatment fluids especially suited for use in far field diversion in low viscosity carrier fluids comprise water, a friction reducer, and a diverter. The diverter comprises dissolvable particulates and proppants. The dissolvable particulates have a specific gravity of from about 0.9 to about 1.6 and a particle size of about 50 mesh or less. The proppants have a specific gravity of from about 0.9 to about 1.4 and a particle size of from about 20 to about 100 mesh. The dissolvable particulates have a higher specific gravity and a smaller particle size than the proppant.

摘要： The present invention relates to a floor panel, a flooring system including the panel and methods of use thereof for forming a graded wet area, floor, pathway or decking. In one form, the present invention provides a floor panel for forming a graded wet area. The panel includes a pair of opposed surfaces including an upper surface and an opposed lower surface interconnected by opposed side edges, a first end edge and an opposed second end edge. The panel further includes a plurality of protrusions protruding from one of the opposed surfaces and extending at least partially across the panel between the opposed side edges, said protrusions protruding at differing heights from the one of the opposed surfaces to define a panel gradient extending between the first end edge and the second end edge.

摘要： In order to develop a fire-protection rolling door of the type in question such that the fire resistance duration and thermal insulation are improved and increased and in particular heat transfer points extending through the door are avoided, a fire-protection rolling door is proposed which is composed of: —a rolling-door armor of profiled plates which interconnected in an articulated manner; —a sheet-shaped intermediate layer of fire-retardant and thermally insulating material; and—overlapping cover plates, which fire-protection rolling door is held, in the open state, above an opening to be closed in the event of a fire, such that the fire-protection rolling door can be guided in guide rails disposed on both sides, the sheet-shaped intermediate layer having planar carrier segments, which are covered with at least one layer of fire-retardant and thermally insulating material on both sides.

摘要： A vehicle system includes a first work machine including a first actuator and a first control system, a second work machine including a second actuator and a second control system, and a user input system including a transceiver and a user interface. The user input system is configured to receive a user input via the user interface and provide a signal to both the first control system and the second control system. The first control system and the second control system are configured to receive the signal and thereafter operate the first actuator of the first work machine and the second actuator of the second machine in a coordinated mode of operation. The user input system is configured to provide, and the first control system and the second control system are configured to receive, the signal simultaneously thereby reducing latency between motion of the first work machine and the second work machine in the coordinated mode of operation.
