Abstract: A device for metering out a paste-like material includes a connector for connecting the mouth of a flexible container to a positive-displacement pump, means for compressing, over a limited area, a bag filled with the paste so that the paste is acted on at this point by shear forces and at the same time squeezed towards the mouth of the bag. A suction pump is located behind the positive-displacement pump. The devices makes it possible to meter highly viscous pastes from flexible bags simply and without interruption, even when the paste includes trapped air.

Abstract: A cleaning vehicle which is suitable for holding and transporting containers and devices for the commercial cleaning and disinfection of floors and other surfaces, consists of a main vehicle with wheels and a trailer with wheels and a coupling for connecting the trailer to the main vehicle. The coupling consists of at least one tow-hook and corresponding eyes in which the hook can engage. The shape of the hook and eyes is such that the coupling allows the trailer to rotate about the connecting line of the eyes of the main vehicle and/or the vertical movement of the trailer in relation to the main vehicle, but no movement of the trailer in the plane of travel in relation to the main vehicle. The wheels of the main vehicle do not lock when taking curves and are stable even on uneven surfaces. At the same time the trailer can be properly steered by the main vehicle without any undesired movements of the trailer. The improvement is also simple and economical.

Abstract: A dispenser container for a paste is provided. The dispenser container is formed from a cylinder open at one end for holding the paste, a displaceable tightly fitted follower plate means is arranged at the open end of the cylinder and a dispenser for transporting the paste from the container is arranged to cooperate with the follower plate. A motor and transmission are mounted near the center of the follower plate and has a shaft which extends through the follower plate and has mounted thereon a multiple blade stirrer. The stirrer rotates in the paste below the follower plate. The dispenser removes the paste from the container at a position away from the center of the follower plate in an area below which the multiple blade stirrer rotates. The multiple blade stirrer by rotating in the paste lowers the viscosity and permits the paste to be more easily transported from the container by the dispenser.

Abstract: The invention concerns an improvement to a movable floor cleaning machine with integral clean and dirty liquid compartments which are separated from each other by a solid partition with an opening which allows liquid to pass through, and is provided with a closure member which can be opened.

The closure member which can be opened is a valve body which is resiliently urged from one side of the partition towards the edge of the opening in the closed position. On the other side, and in the region of the opening, the partition is provided with a tubular coupling connection to one end of which a tubular coupling with an associated filter can be coupled.

Abstract: A method for emptying a substantially, completely compressible container filled with a thixotropic paste, for example, a paste-form detergent. The thixotropic paste is transported by compression by a compressive force of the container toward an opening of the container and through that opening into a connected delivery tube. The compressive force is applied to a limited area of the container to deliver the thixotropic paste which is then transported by a metering pump through the delivery tube to a mixing container where it is mixed with inflowing water.
