Exemplary embodiments include a filling apparatus that can be connected to a valve on a keg, such as a Sankey-D valve, and can be used to pour alcohol and other liquids into the keg, which may be pre-filled with a non-alcoholic drink mix. The filling apparatus has an upper structure which is coupled to a lower portion configured to mate with a keg valve. The filling apparatus may be designed to depress portions of the keg valve to allow for both filling and venting of the keg simultaneously. The filling apparatus may further be designed with features to prevent liquid escape during degassing of the keg. The filling apparatus may include a Sankey-D coupler or a coupler with a probe portion as the lower body portion.

Embodiments of the invention provide a probe assembly configured to selectively restrict fluid flow through an outlet of a closed transfer system. The probe assembly has an elongate probe body with a top end portion, a bottom end portion, an outer wall, and an internal structure defining a fluid chamber extending from the bottom end portion to the top end portion. The fluid chamber has a fluid chamber inlet at the bottom end portion extending through the outer wall into the fluid chamber and a fluid chamber outlet at the top end portion extending from the fluid chamber through the outer wall. A probe tip with a cylindrical bore is configured to engage the top end portion of the elongate probe body and a probe tip outlet is configured to be in fluid communication with the fluid chamber outlet. A rotating head located circumjacent to the probe tip and adjacent to the probe tip outlet is configured to rotate about the probe tip. The rotating head having an inner surface, an outer surface, and a vane extending from the inner surface through the outer surface.

Described herein is a coupling device configured to be mechanically coupled to a cap of a container to be in a coupled configuration. Also described herein are a corresponding method and a corresponding system. In one embodiment, the coupling device is used in combination with a crop protection spray system. The coupling device includes a single probe and a first and a second mechanical mechanism. The first and the second mechanical mechanisms are independent from each other. The first mechanism allows drawing the cap and the container towards the coupling device thereby sealing and locking the cap and the coupling device into a desired position. The second mechanism facilitates actually moving the probe thereby lifting the probe with the closure insert into the container. The coupling device may be embodied as a first, second and third tube which are arranged concentrically.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.

An agricultural method for preventing roll-back of an agricultural vehicle may include receiving a roll-back prevention input from a speed setting device indicative of a command to increase the transmission speed of the hydrostatic transmission while a service brake of the agricultural vehicle is engaged. Further, the method may include adjusting a speed mapping for the speed setting device from a predetermined speed mapping to a roll-back speed mapping in response to the roll-back prevention input, with the roll-back speed mapping being associated with a reduced speed range. Additionally, the method may include determining a transmission control command associated with a current position of the speed setting device based on the roll-back speed mapping and controlling an operation of the hydrostatic transmission to adjust the transmission speed based at least in part on the transmission control command.

A retrieval system for a container having a dip tube and designed to hold a liquid, with a retrieval head which can be fastened to the dip tube, so that liquid can be retrieved from or supplied to the container via the dip tube and the retrieval head. The retrieval head has a liquid channel in which the liquid retrieved from or supplied to the container is conducted. An opening is provided in the wall bounding the liquid channel, wherein when the retrieval head is fastened to the dip tube the opening is closed in such a way that it is secured against the entering of gas, and wherein when the retrieval head is unfastened from the dip tube the opening is no longer closed, so that gas enters the liquid channel via the borehole.

A removal system (1) for a container designed to receive a fluid, with an extraction head (4) and a dip tube (5) that can be fastened thereto. By means of the extraction head (4), fluid can be removed through the dip tube (5) from the container (3) or fluid can be fed into the container (3). The extraction head (4) can be fastened to the dip tube (5) by a displacement movement. Alternatively or additionally, a target position of the dip tube (5) at the extraction head (4) is monitored by means of an optical sensor (12).

A probe assembly configured to selectively restrict fluid flow through an outlet of a closed transfer system. The probe assembly has an elongate probe body with a top end portion, a bottom end portion, an outer wall, and an internal structure defining a fluid chamber extending from the bottom end portion to the top end portion. The fluid chamber has a fluid chamber inlet at the bottom end portion extending through the outer wall into the fluid chamber and a fluid chamber outlet at the top end portion extending from the fluid chamber through the outer wall. A probe tip with a cylindrical bore is configured to engage the top end portion of the elongate probe body and a probe tip outlet is configured to be in fluid communication with the fluid chamber outlet. A rotating head located circumjacent to the probe tip and adjacent to the probe tip outlet is configured to rotate about the probe tip. The rotating head having an inner surface, an outer surface, and a vane extending from the inner surface through the outer surface.

A method of supplying a chemical solution to a photolithography system. The chemical solution is pumped from a variable-volume buffer tank. The pumped chemical solution is dispensed in a spin-coater. The variable-volume buffer tank is refilled by emptying a storage container filled with the chemical solution into the variable-volume buffer tank.

Disclosed is a portable container with a refill structure, which includes: first and second containers that are open towards each other and form a contents receptacle space by being inserted in a watertight and variable way and communicating with each other; a one-way valve attached to the first container to allow the contents to be introduced; and a pump unit attached to the second container to release the contents held in the receptacle space through a nozzle. A negative pressure is generated in the receptacle space by pulling out the first and second containers in a watertight way.
