A reversing flow apparatus comprising a chamber having a series of two or more sequential rings mounted on a shaft extending axially through the chamber, the rings being separated by a space, each ring comprising a circumference and one or more S-shaped members extending from a point in the circumference to another point in the circumference and across a center of the ring, the two or more sequential rings being mounted along the shaft in a twist arrangement such that at least one ring In the apparatus has its S-shaped member in a forward-facing position and at least one ring in the apparatus has its S-shaped member in a reverse-facing position.

A kneading machine for food doughs includes a kneading machine frame with a lower portion and a head portion attached to the lower portion. A kneading bowl can be arranged on the lower portion, a drive to rotate the kneading bowl is provided, and a kneading tool and a drive to drive the kneading tool are held on the head portion. Safety-relevant components of the kneading machine are surrounded by a housing and a major portion of the kneading machine frame is exposed. The exposed kneading machine frame includes struts between which respective free spaces are defined. The kneading machine includes a removable cover which covers at least a major portion of the free spaces defined by the exposed kneading machine frame towards an outside. The cover is fastened to the kneading machine frame and/or the housing by connections which can be released without tools.

One or more techniques and/or systems are disclosed for a colorant dispensing system that has a colorant dispensing head and a platform for holding a target canister into which colorant is dispensed. A light array can be used produce a light pattern in an arc of a circle at a height of an opening of the target canister. The light pattern can be focused at the opening of the target canister, to help a user align the opening with the dispensing head. The dispensing head is configured to dispense colorant within the boundary of the circle, such that the light pattern can act as a type of target for dispensing colorant into the opening of the canister to avoid issues when tinting. A control unit can be used with an interface to control the light array to accommodate different sized and shaped canisters.

A material wetting system for wetting a powder material includes a liquid supply system, a material mixing unit, a material supply system, and a shroud assembly. The liquid supply system includes a supply line. The material mixing unit is in fluid communication with the supply line and includes a central cavity having an open upper end configured to receive a supply of powder material. The material mixing unit is configured to receive liquid from the supply line and is operatively connected to a reduced pressure source to draw air into the central cavity. The material supply system includes an orifice and is configured to feed powder material through the orifice, with the orifice disposed above the central cavity of the material mixing unit. The shroud assembly is disposed about the open upper end of the central cavity of the material mixing unit and the orifice of the material supply system.

An apparatus for preventing proliferation of dust during mixing of material, including a semi-dome shaped element configured for placement over a top opening of a mixing container, a fastener extending along a bottom circumference of the semi-dome shaped element, such that the fastener is configured to couple to the top brim of the mixing container, and an opening in the semi-dome shaped element, the opening configured to accept a vacuum hose.

A system for mixing a batch of medicament has a pump actuator, control valve actuators, a source of concentrate, and a purified water source, all connected by a fluid circuit. A controller controls various control valves to open fluid channels from the source of concentrate and from the purified water source to connect a junction of the fluid circuit to the concentrate container and the purified water source. The controller also controls the pump actuator and a water pump to flow water and concentrate through the junction into a mixing container, such that the mixture of the concentrate and the water requires additional dilution to form a ready-to-use medicament. The controller samples the mixture and calculate an additional quantity of water to add based on the sampling.

An apparatus for preventing proliferation of dust during mixing of material, including a semi-dome shaped element configured for placement over a top opening of a mixing container, a fastener extending along a bottom circumference of the semi-dome shaped element, such that said fastener is configured to couple to the top brim of the mixing container, and an opening in the semi-dome shaped element, the opening configured to accept a vacuum hose.

One aspect relates to a device for mixing a polymethyl methacrylate bone cement formed of two starting components and for storing the starting components of the bone cement. The device has a tubular cartridge with a cylindrical interior. A powder is contained in a front of the cartridge and a container containing a monomer liquid is arranged in a rear of the cartridge. A discharge piston is arranged between the container and the powder, and a conveying piston is on the side of the container opposite the discharge piston. The discharge piston and the conveying piston are arranged in the interior of the cartridge movably in the longitudinal direction. A conduit is provided that connects the front part and the rear part of the interior of the cartridge to one another in a manner permeable for the monomer liquid and for gases and which is impermeable for the powder.

To prevent turbulence on a surface of a plating solution as much as possible and suppress spattering and splashing of the plating solution even when the plating solution is stirred. Provided is a wave absorbing member that is attachable to a paddle moveable in a horizontal direction to stir liquid. The wave absorbing member includes a thin plate shaped body portion configured to move on a liquid surface when moving in the horizontal direction and a front end portion designed to be tapered toward an end from the body portion.

An elevating feed mixing system and method are provided. The system includes a support frame and a raisable platform raisable relative to the support frame. A mixing tub disposed on the raisable platform is configured to receive constituent ingredients of a feed and further configured to raise to release the feed after it is mixed.
