The invention relates to a base station (10) for stationary emptying of a dirt space (41) of a mobile cleaning apparatus (40), comprising a dirt path (11) through which dirt can be transported out of the dirt space (41) of the cleaning apparatus (40), wherein a path input of the dirt path (11) is formed by a coupling element (12) which can be coupled to the cleaning apparatus (40) for emptying of the dirt space (41). Furthermore, the invention relates to a cleaning system (1) and a method (100) for stationary emptying of a dirt space (41) of a mobile cleaning apparatus (40).

<Problem> It is an object of the present invention to provide a timing hopper that inhibits the occurrence of the problem that articles end up getting stuck inside the timing hopper and are not normally discharged.

<Solution> A timing hopper 9 includes a first member 91, a second member 92, and a gate 9a. The first member 91 has a first opening 91a to which articles A are input. The second member 92 has a second opening 92a from which the articles A are discharged. The gate 9a opens and closes the second opening 92a. The first member 91 has a first side wall 91b and a second side wall 91c. The second side wall 91c opposes the first side wall 91b. The second member 92 has a third side wall 92b and a fourth side wall 92c. The third side wall 92b is continuously connected to the first side wall 91b. The fourth side wall 92c opposes the third side wall 92b and is continuously connected to the second side wall 91c. The height position where the first side wall 91b and the third side wall 92b are interconnected is different from the height position where the second side wall 91c and the fourth side wall 92c are interconnected.

A lock-out pinion can be coupled to a center sump control shaft to rotate therewith. A lock-out slide can include a rack and a blocking cover. A lock-out guide can be coupled to the sump control housing and can form a guide channel. The lock-out slide can be received in the guide channel with the lock-out pinion drivingly coupled to the rack to move the lock-out slide along the guide channel from a lock-out position in which the blocking cover prevents rotation of the intermediate sump control shaft with the driving handle, to an unlocked position in which the blocking cover permits rotation of the intermediate sump control shaft with the driving handle, in response to manual rotation of the center sump control shaft in the center sump opening direction.

Embodiments of the invention provide a method for delivering a supply of one or more deicing and anti-icing agents for localized seasonal storage and application at a facility. In advance of a winter season, a deicing agent or anti-icing agent according to embodiments of the present invention may be provided by a provider to a receiver in a delivery quantity for storage at a localized storage location at a facility. A deicing agent may be a salt compound treated with an additive which reduces bridging of salt granules. The provider may provide multiple storage containers each filled with a delivery quantity of anti-icing agent and may provide multiple storage containers each filled with a delivery quantity of deicing agent to a receiver, as well as one or more delivery stations. After receipt of an initial quantity of a deicing agent or anti-icing agent, the receiver may deploy a delivery station and set up a storage container with the delivery station. The receiver may move a sprayer unit or a spreader unit to the delivery station for filling. Upon depletion of some or all of the contents of an anti-icing container or the contents of a deicing container, the receiver may contact the provider to request that the provider replenish the anti-icing agent or the deicing agent.

A system and mechanism for bottom ash flow turndown from a hopper, through a crusher, and to a conveyor, the system including a fixed flow restrictor and a variable speed side discharge crusher to modulate bottom ash flow in the absence of gate or valve flow from a hopper.
