A process for operating an extrusion system is provided. An extrusion device is provided that has at least two extrusion pistons operable with different feed ratios. The process involves storing a ratio of feed rates of the extrusion pistons in a storage device of the control device in dependence on the second signal. A least one drive device is actuated by the control device for displacing the two extrusion pistons into a start position, in which a plunger of the first extrusion piston substantially abuts the first cartridge of the cartridge device and a plunger of the second extrusion piston substantially abuts the second cartridge the cartridge device. The at least one drive device is actuated by the control device with a ratio of feed rates stored in the storage device of the control device for the extrusion pistons at user request.

Methods, apparatus, devices and systems for mixing and dispensing multi-component materials. The mixing and dispensing may be performed using a mobile, enclosed dispenser that can be used to supply a mixed multi-component material at the point of use. In some embodiments, the components to be mixed into the multi-component material may be supplied in cartridges.

An extrusion device (11) for compound-containing containers (6), including a receiving chamber (12) for the container (6), a piston rod (13) which is displaceable relative to the receiving chamber (12), a motor (21) for moving the piston rod (13), a trigger member (26) for generating a control signal in response to actuation of the trigger member (26), and a control unit (31) for controlling the motor (21) is provided. The control unit (31) has a power module for connecting the motor (21) to a power supply (19), and a separate signal input which is electrically connected to the trigger member (26). The power module connects the motor (21) to the power supply (19) when the corresponding control signal is present at this signal input. A method for controlling such an extrusion device (11) is also provided.

A station for covering a bread roll half of a bread roll with a sauce in a preparation line of a fast food restaurant, comprising: a table by which a user standing at a front side can cover a bread roll half with sauce, a container comprising the sauce and arranged over the table at a working distance from the front side and from which an outlet nozzle oriented towards the table protrudes at a vertical distance from the table, so that the bread roll half which is to be covered with sauce can be placed on the table below the outlet nozzle, and a pressure actuator that can be actuated by the user and which is designed to dispense the sauce from the container onto the bread roll half when actuated by the user.

Problem: To provide a fluid transfer device that can solve an issue of pulsation that occurs when a liquid material is discharged from a nozzle by eccentrically rotating a male-screw-shaped rotor within a stator having a female-screw-shaped insertion hole, an application device including the fluid transfer device, and an application method.

Solution: A fluid transfer device 1 includes: an outer cylinder 10; a stator 11 that has a female-screw-shaped insertion hole 12 as a through-hole and is provided on an inner periphery of the outer cylinder; and a male-screw-shaped rotor 20 that is connected to a rotor driving part and eccentrically rotates in contact with an inner periphery of the stator. In the fluid transfer device 1 capable of transferring a fluid in a transport path formed by the stator 11 and the rotor 20, by rotating the rotor 20 inserted through the insertion hole 12, contact force with the rotor 20 at an inlet portion and an outlet portion of the stator 11 is smaller than contact force with the rotor 20 at a central portion of the stator 11.

A distributor head for a distributor apparatus for distributing fluids onto a surface includes an elongate base element having a fluid volume to receive the fluid, a filling opening connected in a fluid-communicating manner to the fluid volume to fill the fluid into the fluid volume, and a plurality of distributor openings connected in a fluid-communicating manner to the fluid volume to distribute the fluid from the fluid volume. The filling opening arranged at a first longitudinal side of the distributor head and the plurality of distributor openings arranged at a second longitudinal side of the distributor head, the first longitudinal side arranged opposite the second longitudinal side, and the plurality of distributor openings continuously formed in a wall of the base element.

A powered caulking apparatus includes a power source, a motor, a drive gear, an extension tape, and a top roller guide and bottom roller guide. The tape includes extension tape slots that receive gear teeth of the drive gear such that rotational motion of the drive gear translates into linear motion of the extension tape. The extension tape preferably comprises a radius, and the top roller guide and bottom roller guide preferably conform to the radius of the tape. The top roller guide and bottom roller guide may form an interference for the tape while still allowing linear motion of the tape. The apparatus may extend the tape to cause the tape to exert a force on a caulk tube to extrude caulk, and the tape may thereafter reverse linear motion of the tape to remove the force of the apparatus on the caulk tube.

A dispenser assembly includes a rod, a plunger and a stopper. The rod has a plunger receiving end with a clip receiving recess. The plunger has a rod receiving structure with a rod engaging clip biased to fit to the clip receiving recess of the rod for movement therewith. The stopper has a plunger receiving space that defines an aperture extending through the plunger receiving space with the rod extending through the aperture. The plunger receiving space is dimensioned such that with the rod receiving structure of the plunger located within the plunger receiving space, movement of the rod engaging clip is restricted by contact with surfaces of the plunger receiving space preventing release of the rod from the plunger.

A product applicator assembly including a housing having a first end and a second end;

a dispensing force; a dispensing device operatively attached to the dispensing force; at least one power source; a dispensing switch operatively attached to the dispensing force; a data operator electrically connected to an electrical power source. Also provided is a bait applicator and a method of using the applicator to apply bait.
