Abstract: A multistage ejector has a nozzle arrangement, which has at least three nozzles which are arranged in series in the direction of a longitudinal axis, wherein the nozzles are designed for passage of a throughflow of a fluid, wherein a fluid gap is provided between adjacent nozzles in each case, wherein at least two of the at least three nozzles are interconnected monolithically to form a nozzle string, and wherein the nozzle string is arranged at least partially in a sleeve and the nozzle string and the sleeve are detachably fastened to each other. The nozzle string and the sleeve are axially fastened to each other by fastening mechanism which acts in a positively locking manner.

Abstract: Needle gripper features a gripper unit with a gripping surface facing a workpiece to grip, and a needle carriage with a gripping needle. The needle carriage moves into an active position extending the gripping needle beyond the gripping surface by one needle stroke depth, and in a passive position retracting the gripping needle, and features a drive unit with a drive actuator driven forward/backward along a drive direction that couples to the needle carriage so it moves into the passive/active positions by driving the drive actuator forward/backward. A setting device for setting the needle stroke depth includes a guide carriage displaceable perpendicularly to the drive direction along a guide direction, and a stop for the guide carriage. The drive actuator couples via connection arm to the guide carriage so when the drive actuator moves backward, the guide carriage moves in the direction toward the stop, which prevents further backwards movement.

Abstract: Needle gripper comprising a gripper unit with a gripping surface (20) facing the workpiece to be gripped, and at least one needle carriage (32) with at least one gripping needle (22), wherein the at least one needle carriage can be displaced into an active position in which the gripping needle is extended beyond the gripping surface by one needle stroke depth (24), and in a passive position in which the gripping needle is retracted, and comprising a drive unit with a drive actuator (26) which can be driven forward and backward along a drive direction, wherein the drive actuator is movably coupled to the needle carriage so that the needle carriage can be moved into the passive position and into the active position by driving the drive actuator forward and backward, and with a setting device (34) for setting the needle stroke depth, which comprises a guide carriage (38) which can be displaced perpendicularly to the drive direction along a guide direction (36), and a stop (54) for the guide carriage, wherein the

Abstract: A pneumatically actuated area vacuum gripper for gripping and, if necessary, separating workpieces is provided by the present disclosure. In particular, the vacuum gripper is used with thin, flexible workpieces, and has a suction chamber, which has a suction wall with perforations, to be placed on the workpiece. An ejector nozzle has a connection and an outlet, the ejection nozzle being connected to the suction chamber via its connection, and the outlet of the ejector nozzle opening to the outside or into an exhaust air duct, and the suction inlet of the ejector nozzle empties into the suction chamber, whereby the direction of the air stream in the connection coming from the suction chamber corresponds to the direction of the main air conveyance in the ejector nozzle.

Abstract: The invention concerns a vacuum gripper for suctioning workpieces with an vacuum port, an elastic vacuum element and a vacuum element holder, wherein the vacuum element has a sealing lip on its side facing the workpiece, which delimits the vacuum chamber, and the vacuum chamber is flow-connected to the vacuum port, wherein the vacuum gripper has means that display the suction state, whose color changes.

Abstract: Methods are disclosed for simulating custom hair color results, for selecting a resulting custom hair color from among possible custom hair color results, and for formulating custom hair coloring compositions which impart to hair such custom hair color results.

Abstract: A service trolley (1) having a pedestal (2) on which rollers (3) are provided for moving the service trolley (1) and having at least one holding surface (4, 5, 23, 25) on a support beam (6) is provided for use in a hair salon. In order to be able to carry out a dust-free production of hair coloring right next to the hairdresser's customer, it is proposed that a holding surface (4) has a device (7) for holding granulate (8) for hair coloring purposes. The granulate (8) can be dosed in a simple manner and also can still be used after longer periods of storage.

Abstract: A device (1) comprises a reservoir (2), preferably having a transparent wall (8), for holding a flowable product (3) and a dispensing head (4) for discharging the product (3). The dispensing head (4) is joined to the reservoir (2) via a coupling (5), especially a threaded coupling. Provided on dispensing head (4) is an actuator device (6) for opening and closing the dispensing head (4) as desired in order to dispense product accordingly from a discharge opening (18). In order to prevent erroneous refilling with product when an empty reservoir (2) is replaced with a full reservoir (2), especially when there is a set of reservoirs (2) having different products (3) for coloring hair, it is proposed that the product (3) be a powdered or granulate hair dye and that the surface of the dispensing head (4) or the actuator device (6) have an information surface (7) that is to be assigned to the product (3). The powder or granulate form thus serves to ensure recognition of the color of the product (3).
