摘要： A balance with a draft shield enclosing a weighing pan (33) has slidable walls (6, 7, 8) with slide handles (10, 110, 210) to open and close the weighing compartment (2). A connector body (22) serves to couple non-adjoining slidable walls (6, 7, 8) to each other. Besides for pushing the slidable walls open and closed, the slide handles (10, 110, 210) also serve to couple and uncouple the slidable walls, so that more than one wall can be moved simultaneously using only one hand, or a wall can be moved by pushing a handle on the opposite side. The slide handles are configured as pairs of handle elements that are attached either to adjoining walls or to a wall and an adjoining place on the connector body. In the coupled state, the pairs of handle elements are folded or swiveled into each other, working as a single handle, e.g., for two adjoining walls. In the uncoupled state, they move the walls individually.

摘要： A balance is connectable to a display/operating unit (13) through a cable (14). The display/operating unit (13) can be placed either adjacent to the housing (1) or at a distance from the housing (1). For storing the unused length of cable (14), a corridor compartment (24) with at least one exit opening (22, 29, 30) for the cable (14) is arranged at the bottom (6) of the balance housing (1). When the cable (14) is pulled out or pushed in, it can move freely inside the corridor compartment (24). The display/operating unit (13) is held in place at the balance housing (1) by means of an intermediate member (10) in an arrangement where the balance and the display/operating unit are resting independently of each other on a supporting surface.

摘要： A support device for a weighing cell is mounted on one or more support posts resting on support springs that are connected to a stationary chassis and are pre-tensioned with an upward force. In case of a downward-directed shock, the support springs will yield to the inertial shock force and allow the weighing cell to move downward. The support posts can lift off from their resting places on the support springs, but are constrained by guide members to a limited range of upward vertical movement. A balance equipped with the support device has a low profile height and protects the weighing cell from downward- as well as upward-directed shocks.

摘要： A dispensing apparatus for granular or powdery bulk materials includes a balance (15) to weigh the doses of material being dispensed, a reservoir container (1), and a cover (2) to close the downward-facing opening of the storage container (1). Integrated in the cover (2) is a conveying and delivering device with a vertically movable, rotary conveyor body (5) designed so that it can substantially close off the dispensing outlet (14) for the bulk material. The conveyor body has a ring-shaped bottom (6) sweeping a ring-shaped conveyor channel (7) that is recessed in the cover (2). The outlet (14) is arranged in the ring-shaped channel (7) and is designed to deliver a directed and locally concentrated stream of bulk material.

摘要： A receptacle for the weighing-in of free-flowing substances has a fill opening, a tubular-shaped circumference wall, and a bottom part. The bottom part is connected to the tubular-shaped circumference wall, which it tightly closes off in the direction of gravity when the weighing receptacle is in its operating position. The weighing receptacle can be set on the weighing pan of a balance and can be filled like a beaker with free-flowing substances without allowing the latter to escape therefrom. The bottom part can be opened either by an outside force acting on the weighing receptacle and/or through the influence of a solvent acting on the weighing receptacle, forming an outlet orifice in the bottom part. The weighing receptacle, otherwise tightly sealed in the direction of gravity, can be flushed out with a fluid when the outlet orifice is opened.

摘要： A draft protection device for a laboratory instrument. The device encloses a weighing compartment that surrounds a balance pan. The draft protection device includes a rear wall, a front wall, two sidewalls, a top cover, and a floor that is delimited by border edges. The draft protection device further includes at least one guiding means that is connected to the top cover and serves to guide the movement of at least one horizontally slidable sidewall, and/or a holder means that is connected to the top cover and serves to hold the front wall in place, wherein the guiding means and/or the holder means supports the weight of the at last one sidewall and/or the front wall in such a way that the wall(s) is pushed by a biasing torque against the floor of the weighing compartment. This torque is supported by the border edge facing towards the respective wall.

摘要： A dispensing head for a powder or paste dosage material has a housing with an outlet opening, a bearing- and passage area, and at least one socket connected to a source container. A feeder chute is formed inside the housing. A closure shaft is in the bearing- and passage area, free to rotate about and to slide along its central longitudinal axis. The closure shaft is connected to a closure element arranged near the outlet opening. Moving the closure shaft in the axial direction controls the volume flow of the dosage material through the outlet opening. A limit stop restricts the displacement of the closure shaft along its central longitudinal axis. In the feeder chute, an opposing stop defines the closed position where the limit stop rests in direct contact against the opposing stop and the outlet opening is closed off by the closure portion of the closure element.
