  • Publication number: 20240418563
    Abstract: A guideway receives and guides a carriage and includes a guideway body having a first and second longitudinal end and a longitudinally extending clear channel which is bordered by a wall of the guideway body and opens at the first longitudinal end. A stop member terminates the guideway at the first longitudinal end and includes a crossbar and two legs extending therefrom. The crossbar extends transverse to a longitudinal direction of the clear channel and the legs extend transverse to the longitudinal direction and transverse to the crossbar. The legs have a clearance therebetween. The stop member forms a frame enclosing a window, and has an opening on an edge of the window transversely opposite the crossbar, thereby defining an open side of the stop member.

  • Patent number: 10399721
    Abstract: A device dispenses dosages of a substance in powder- or paste form contained in a supply container, when a head (1) of the device is connected to the supply container. The head has a housing with an outlet opening (107) of circular cross-section and a delivery- and closure element (100). The outlet opening and the delivery- and closure element are arranged on a central lengthwise axis (15) of the head. The delivery- and closure element rotates relative to the housing about this axis and is arranged for translatory displacement relative to the housing along the axis. The delivery- and closure element is cylindrical in its fundamental contour shape. A closure portion (101) thereof closes off the outlet opening. A delivery portion (102) is adjacent to the closure portion and delivers substance that is to be dispensed. A shaft portion is adjacent to the delivery portion. A conveyor body (103) on the delivery portion conveys substance to the outlet opening.

  • Patent number: 9440753
    Abstract: A head (5) is associated with a device (1) for dispensing measured dosages of a free-flowing material. The head has housing (3) with an interior space (59) with a fill opening (57) and a discharge orifice (62). A shutter bolt (80) is arranged in the housing to open and close the discharge orifice (62) and to loosen and advance the material. The head (5) has a dispensing position, in which the shutter bolt is oriented substantially vertically and a fill position. In the dispensing position, the material is dispensed through the discharge orifice (62). In the fill position, material is filled through the fill opening (57), which is positioned laterally on the housing when the head is in the dispensing position. A rest surface (51) is diametrically opposite the fill opening, so that the head lies on its rest surface in the fill position.

  • Patent number: 8678242
    Abstract: A device (110, 10) dispenses dosages of a free-flowing substance from a source unit (70) containing the substance. The device has a base unit (120, 20) and a receiving unit (130, 30), so that the source unit can be set into, and removed from, the receiving unit. An actuator (150, 50) generates repeated bidirectional pivoting movements of the receiving unit about the base unit. A connector unit (140, 40), arranged between the base unit and the receiving unit, pivotally supports the receiving unit, providing rotational mobility about a pivoting axis. The connector unit is slidably supported with translatory mobility relative to the base unit. The actuator generates repeated bidirectional translatory movements of the base unit. In this way, the receiving unit is subjected to repeated bidirectional pivoting movements and, superimposed on the latter, repeated bidirectional translatory movements.

  • Patent number: 8648719
    Abstract: A container unit for the storage and protection of laboratory substances includes a protective housing and at least one dosage-dispensing unit. The at least one dosage-dispensing unit includes a reservoir container and a dispensing head. To prepare the at least one dosage-dispensing unit for operation, the protective housing can be removed from the dosage-dispensing unit. The protective housing has a bottom part with at least one suitably shaped recess to provide a stable seat for the at least one dosage-dispensing unit, as well as a bell-shaped top. The top can be connected to the bottom part, so as to form a tightly sealed interior space. For transportation and storage purposes, the at least one dosage-dispensing unit is arranged in the interior space of the closed protective housing.

  • Publication number: 20130340882
    Abstract: A utensil (1) for weighing a sample (6) has fill (2) and discharge (3) positions. The utensil has a receptacle (4) with an attached neck (5). An outside surface (7) of the receptacle has a seating surface (9) that defines a plane, as well as a fill opening (13), through which the sample is placed when the utensil is in the fill position. A passage opening (15) and a discharge opening (14), at the ends of the neck, allow sample flow from the receptacle through and out of the neck when in the discharge position, with flow into the neck occurring between the fill and discharge positions. The neck has at least one support contact point in the plane of the seating surface, so that the receptacle rests on both the seating surface and the at least one support contact point when in the fill position.
