A cleaning apparatus, optimized for cleaning optical and optoelectronic sensor devices in motor vehicles, comprising a housing, and a reciprocating piston movable in a pressure-controlled manner in the housing and movable from a retracted position into a deployed position along an actuation axis is disclosed. The reciprocating piston has an inner channel to transport a cleaning fluid through the reciprocating piston to a spray nozzle. A miniaturized, easily and inexpensively producible cleaning apparatus which makes possible exact and precise orientation of the cleaning jet, quick operational readiness, reduced tendency for follow-up flow of the cleaning fluid, and improved adaptability to different installation positions, is also disclosed. In an embodiment at least the cleaning apparatus has at least one guide to prevent rotation of the reciprocating piston about the actuation axis during its entire stroke, the at least one guide means arranged at least regionally in the inner channel.

A variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion are disclosed. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed. The present disclosure also provides a single force generation mechanism, a deformable container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier; a system that may also include a pressurized air source that assists a flow of a fluid; and a system that allows for a continuous flow a substance. The systems of the present disclosure provide a deformable container and a method of dispensing wherein, during dispensing, an actuation member is continuously free of contact with the fluid or substance within the container and the actuation member only contacts the exterior surface of the deformable container.

The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

An unmanned aerial vehicle (UAV) includes a sprayer configured to generate a pressurized fluid flow and a nozzle configured to receive the pressurized fluid from the sprayer and to generate a spray fan to apply the fluid to a surface. The UAV includes sensors and a control unit to control both flight of the UAV and spraying by the sprayer. The fluid can be stored onboard the UAV in a reservoir or can be remotely stored and pumped to the UAV. The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

A hydration system is provided. The hydration system includes a container configured to receive and maintain a quantity of liquid, a pump connected to the container, a hose system comprising a plurality of hoses connected to the container and the pump and configured to receive liquid from the container, and an end piece connected to one of the plurality of hoses configured to be used by a user of the hydration system. The pump is configured to circulate liquid through the hose system and container to maintain a relatively similar liquid temperature for all liquid contained in the hose system and container.

The disclosure relates in particular to an apparatus for disinfecting at least one room, in particular for one or more persons, preferably a dwelling space or treatment room, for example a treatment room in a building, in particular a sickroom, a patient room and/or an operating theatre, by means of an atomiser. Specifically, the apparatus is characterised in that the atomiser includes a rotatable bell cup for atomising a disinfectant into the room. The disclosure relates to an associated method and furthermore to the use of a bell cup for atomising a disinfectant in a room for, in particular, one or more persons.

A fluid pressure-feed device includes a main tank and a sub tank. The sub tank is connected integrally with an upper portion of a main follower plate that applies pressurizing force to a urethane adhesive inside the main tank. A drum pump is provided in an upper portion of a sub follower plate provided in the sub tank. While the urethane adhesive is flowing into the sub tank from the main tank, the urethane adhesive is fed under pressure from the sub tank to a fluid passage by actuation of the drum pump. While the main tank is being replaced, the urethane adhesive inside the sub tank is fed under pressure to the fluid passage by the drum pump.

This invention relates to any field where crafts (such as avionics) where inhabitants of volumes like passage compartments can be found where the area is subject to extreme conditions such as explosion, fire or other traumatic activity linked with a crash, and more specifically a pressurized dual-compartment canister or anti-trauma apparatus for the storage, mixing, and blast-release of a neutralizing chemical compound within the environment of the volume in a craft placed adjacent to the volume for the blast release of a quickly expanding and quickly retracting product.

A liquid mixture supplying device is provided for mixing a liquid mixture of a liquid and a powder and supplying the liquid mixture to a spray valve for spraying. The device has a structural design consisting of a containing vessel, a driving device, a dip tube and a scraper. The containing vessel is provided for storing the liquid mixture, and the driving device drives the containing vessel to rotate while a scraper disposed on a side of a dip tube is being used for distributing the liquid mixture. The containing vessel is installed in a tiltable external cavity, and a flow barrier is formed on an inner wall of the containing vessel, and the driving device drives the containing vessel to move by a magnetic force or a transmission shaft, so as to achieve the effect of uniform mixing.
