  • Patent number: 5787600
    Abstract: A dryer mounted in a housing with a balance for determining the moisture content of material to be weighed which is in a dish placed in the balance and is subjected to a heat source. The dish is placed in a dish support device which can be placed in and removed from the dryer together with the dish. The dish can be inserted into the dish support device and removed from the dish support device manually and from the side. An upwardly bent inner edge of a support ring prevents impurities resting on the support ring from unintentionally dropping into the dish.

  • Patent number: 5298688
    Abstract: A top or side wall of a weighing scale housing includes a plurality of relatively movable segments that are slidably displaceable between closed and open positions, thereby to afford access to a weighing chamber defined within the housing, at least the longitudinal edge portions of the segments being in continuous overlapping relation. The end portions of the segments are guided within guide grooves formed in the housing wall on opposite sides of an access opening contained therein. Catch devices connected with the longitudinal edges of successive segments are engaged upon displacement of a first segment relative to the housing, thereby to effect corresponding displacement of a second segment.

  • Patent number: 5264667
    Abstract: A weighing scale housing (9) includes a base (21), vertical front (19), rear (17), and side (23,25) walls cooperating with the base to define a weighing chamber (3) containing a movable weighing pan (5), characterized in that at least one of the side walls includes a plurality of planar side wall segments (27, 29; 31, 33) arranged at an obtuse angle, the one side wall being mounted for movement along an arcuate path between an open position affording access to the weighing pan, and a closed position closing the weighing chamber. When in the open position, the side wall is adjacent the rear wall, and when in the closed position, the forward vertical edge (51,53) of one segment engages the rear surface of the front wall, and the rear vertical edge portion (55, 57) of the other segment engages an end portion of the rear wall, thereby tightly sealing the weighing chamber.
