A vacuum tank with a rear door, and air and material hoses connectable to the tank door. The tank is rotatable, while the door remains stationary. Liquid, particulate, or slurry material can be vacuumed into the rotating tank, without twisting the hoses. Additional water and/or drying agent can be added to the tank to create a slurry mixture, which can then be discharged from the tank at a convenient dump or work site. The tank may be mounted on a truck, trailer, or frame for transport to a job site and the dump or work site. In an alternative embodiment, the tank may be tilted end-to-end between fill and discharge positions.

A valve for controlling a product flow, comprising a valve body and a rotatable stem with an end portion of the stem disposed within a product flow channel of the valve, and a disk arranged on the stem at an angle greater than zero relative to an elongated extension of the stem for sealing respectively opening the valve closure area by rotating the stem approximately 180, the valve body comprising a stem seal groove having a stem seal that surrounds the stem, and a void space surrounding the stem and extending from the stem seal to the product flow channel, such that the stem seal is fluidly connected to the product flow channel via the void space. A mixing unit for mixing a liquid product with a powder product and a method for mixing a liquid food product with a powder food product are also disclosed.

A liquid polymer dosing and mixing chamber and pump having a hollow chamber, a blending reactor, a progressive cavity pump, a mixing cup, a submersible actuator, and an aging cup within the hollow chamber adapted to create doses, via the progressive cavity pump, of a first substance and to mix it with one or more substances introduced into the blending reactor via one or more inlets.

Disclosed is a drinking system (1) with a drinking vessel (2) defining a receiving chamber (3) for a liquid, a drinking straw (4) arranged on the drinking vessel (2), projecting from the drinking vessel (2) and guided into the receiving chamber (3), with a first end having an inlet opening (5) which projects towards a base of the receiving chamber (3), and with a second end having a drinking opening (6), and with a suction channel (7) between the inlet opening (5) and the drinking opening (6), and an aroma reservoir (8) connected with the drinking straw (4) via an inflow channel (9).

According to the invention, the drinking system is characterized in that the aroma reservoir (8) contains a liquid aroma medium which contains fragrances and/or flavorings in dissolved or emulsified and thus diluted form and which, when liquid is sucked from the drinking vessel (2) through the drinking straw (4), is sucked through the inflow channel (9) into the drinking straw (4) and is mixed there with the liquid sucked into the drinking straw (4) from the drinking vessel (3).

The powder transfer system includes a transfer pipe, through which powder is transferred, having a plurality of sections along the powder transfer direction, a plurality of sensing units provided for each section of the transfer pipe and provided to detect vibration of the transfer pipe when the powder is transferred for each section, a plurality of vibration units provided to apply vibration to each section of the transfer pipe, and a control part provided to individually control operation of the vibration unit for each section of the transfer pipe based on vibration data obtained from the sensing unit for each section of the transfer pipe.

A method for manufacturing a dry electrode for a secondary battery is described, involving the use of a mixer to combine materials without the use of solvents. The process begins by supplying a conductive material into the mixer, followed by the distribution of an electrode active material onto the conductive material. The mixer is then driven to ensure thorough mixing and complexing of the materials. A binder is introduced after the active material and conductive material have been combined, and the mixer is driven again to fiberize the binder. The resulting dry electrode mixture is then formed into a film using a roll press. This method allows for efficient production of dry electrodes with improved energy density and reduced manufacturing time and cost, offering a solvent-free alternative to traditional wet processes.

A device for providing a bone cement paste from two starting components, comprising a hollow cylindrical cartridge with an interior space, wherein, in a proximal part of the interior space, a bone cement powder is stored as the first starting component, and, in a distal part of the interior space, at least one bag containing a monomer liquid as the second starting component is stored, wherein the interior space is connectible at the proximal part of the interior space to a negative pressure source via a vacuum connector, wherein a dispensing plunger, which is movable axially in the interior space, is arranged between the bone cement powder and the at least one bag, and a feed plunger, which is movable axially in the interior space, is arranged on a side, axially opposite the dispensing plunger.
