  • Patent number: 10900828
    Abstract: A laboratory balance (1) has a weighing pan (14) in a weighing chamber (10). A rear wall (4) separates the weighing chamber separates from a housing (11) that contains a weighing cell (12) with a load-receiving structure (13). A suspension pin (27) extends in a transverse direction of the load-receiving structure. The weighing pan is engaged with the load-receiving structure through at least one passage opening (31) in the rear wall. Two spaced-apart sidebars (29) of the weighing pan are held together by a connecting member (30). Each sidebar has an L-shaped configuration with a horizontal foot portion (55) and a vertical leg portion (56). A hook-shaped portion (64) of the vertical leg is seated on the suspension pin, through sliding contact between the suspension pin and a guiding portion (65) that extends from the hook-shaped portion away from the horizontal foot portion, sloping upwardly.

  • Patent number: 9360405
    Abstract: An instrument (10) for gravimetrically determining moisture content has a housing (20), with a weighing device (40) arranged inside. The weighing device (40) has a load receiver (60) onto which a sample (62) is placed. The housing has a stationary housing part (21) and a movable housing part (22), the movable housing part alternately occupying a measuring position and a loading position. In the loading position, the respective housing parts are spaced apart from each other, allowing a sample to be put on the load receiver. In the measuring position, the respective housing parts form an essentially enclosed testing compartment (30) that surrounds the load receiver. A means (70), arranged in the testing compartment, heats a sample that is placed on the load receiver. The movable housing part is moved between the respective positions by a position-changing device.

  • Patent number: 9329114
    Abstract: An instrument (10) for gravimetrically determining moisture content has a housing (20), with a weighing device (40) arranged inside. The weighing device (40) has a load receiver (60) onto which a sample (62) is placed. The housing has a lower, stationary housing part (21) and an upper, movable housing part (22), the movable housing part alternately occupying a measuring position and a loading position. In the loading position, the respective housing parts are spaced apart from each other, allowing a sample to be put on the load receiver. In the measuring position, the respective housing parts form an essentially enclosed testing compartment (30) that surrounds the load receiver. A temperature sensor (80) is arranged so that the temperature sensor is above the load receiver in the measuring position and is essentially to the side of the load receiver in the loading position.

  • Patent number: 7129427
    Abstract: A balance (1) with a housing (3) containing the weighing mechanism and associated electronic components has at least three positioning feet (5, 5?) to stand on a supporting surface (20), at least two of the positioning feet (5) being height-adjustable for setting the balance (1) into a level position. In addition, the balance (1) has at least one stabilizer foot (6, 106) which can be locked and unlocked, so that for adjusting the level position of the balance, the stabilizer foot is released and thereby enabled to stay in contact with the supporting surface (20), and after the level adjustment of the balance has been completed, the stabilizer foot is locked in place to secure the stability of the balance (1) in its set position.

  • Patent number: 6909058
    Abstract: A balance (1) has a weighing compartment (4) that borders on a stationary part (8, 9) of the balance and is otherwise enclosed by at least one side wall panel (5, 6), a front wall panel (7), and a top cover panel (12). At least one of the panels is slidable by means of a guiding device (17, 20) to open and close the weighing compartment (4). The balance (1) further has cutout passages (20) in the side wall panels (5, 6), the front wall panel (7), the top cover panel (12), and/or the rear wall of the weighing compartment, so that cables and/or conduits can be introduced from the outside into the weighing compartment.

  • Patent number: 6686545
    Abstract: A balance (1) has a weighing compartment (4) that borders on a stationary part (8, 9) of the balance and is otherwise enclosed by at least one side wall panel (5, 6), a front wall panel (7), and a top cover panel (12). At least one of the side wall and top cover panels is slidable by means of a guiding device (17, 120) to open and close the weighing compartment (4). A holder arrangement (15, 17c, 58, 125) for the at least one slidable panel (5, 6, 12) is integrated in the guiding device (17, 120), and a holder arrangement for a non-slidable panel is integrated in the stationary part (8). The holder arrangements (15, 19, 17c, 58, 125) releasably connect the panels (5, 6, 7, 12) to the balance by means of form-locking closure devices, so that each panel (5, 6, 7, 12) can be attached to the balance as well as released for removal from the balance by applying a force to the panel (5, 6, 7, 12) and/or the holder arrangement (15, 19, 17c, 58, 125).
