Abstract: A device for topping-off a substantially filled bag with a final charge of particulate material to provide a predetermined final charge weight in the bag is herein disclosed. The device comprises a lower frame supported upon a plurality of load cells and an upper frame supported above the lower frame also upon a plurality of load cells. The upper frame has rotatably suspended therefrom a pair of carriage assemblies which support respective housings. Each of the housings has disposed therein a belt capable of linear motion. The belts are exposed on an inner face of each of the housings such that when the carriage assemblies are rotated toward one another, the respective belts meet one another and are able to engage the opposed faces of a bag. A plurality of bag grasping means are mounted upon the respective housings so as to be able to grasp and hold the opposed faces of the bag received between the belts to open the bag as the housings are rotated away from one another.

Abstract: A container-filling-and-weighing device having a frame and a connected weighing member. A first single point load cell is connected near the top of the weighing member and attaches to the frame. A second single point load cell extends from near the bottom of the weighing member and attaches to the frame. The load cells are preferably parallel, essentially identical and intersected by a vertical line. Any nonvertical force applied to the upper load cell is offset numerically by an equal and opposite nonvertical force applied to the lower load cell. These disparities are removed by averaging the numerical output from each load cell.

Abstract: Automated tracking devices for counting, sorting, weighing, and containing articles, such as sponges that contain fluids from patients undergoing surgery. Devices according to the present invention employ a suspended container for receiving and sorting the articles. The cumulative weight of the container contents is sensed accurately and registered reliably after an appropriate settling period via a load cell structure which is aimed at eliminating bending moments and non-vertical force components imposed by the container and its contents. Automatic sensing of the presence of the container allows continuous, rather than solely end-point, fluid monitoring during the surgical procedures and allows this monitoring to continue as successive containers are changed during an operation. Appropriate warnings occur after a predetermined number of articles have been introduced into the container, in order to indicate that a container change is due.

Abstract: Granular material stored in a hopper is dispensed therefrom by a rotatable auger which conveys the material to a discharge port for dropping into an underlying container. The container is supported by pivoted arms which are operably connected to a weighing scale for indicating the weight of the material dispensed into the container. The arms are adapted to be swung by the container between closed positions embracing and holding the container and open positions releasing the container.

Abstract: There is disclosed, a gross weight scale for filling material which can be poured or which can flow. The filling material is weighed by means of weighing cells and is filled by way of a filling connection into a bag suspended therefrom and is then compressed. In order to keep the weighing cells free of the compressive forces and so as to be able to check between each filling of the bag, the zero points of the cells in respect of permitted weighing tolerances, the filling connection is constructed as a structural unit which is separate from the filling container and is loosely suspended by means of a hanger arrangement from the weighing cells, which are attached to the filling container, and a decoupling arrangement is provided for bringing the filling connection out of operative engagement with the hanger arrangement.

The machine also has a bag support guide which comprises two upper parallel guides and two lower parallel guides which are disposed in each instance on both sides of the bag support column and whose bearings are constructed as articulated heads. A possible lateral tilting of the bag support column is effectively prevented, without impairment of the vertical movement of this bag support column. The two upper parallel guides and the two lower parallel guides are rigidly connectd to one another by a respective coupling rod.

Abstract: A urinary output monitor for determining the volume of fluid in a urinary collection bag during the collection process having a weighing apparatus for weighing the contents of a collection bag and means for substantially isolating the end of a drainage tube from applications of significant forces to the collection container. The isolation mechanism is incorporated into the container assembly in the form of a conduit for interconnecting an inlet connector and an outlet connector which has sufficient flexibility to preclude it from conveying any significant force in a direction along its length which would adversely affect the weight measurement. Since varying forces applied to the weighing apparatus by drainage tube connectors of different catheters are eliminated by the isolation mechanism, fluid entered after offset determination for zeroing the weighing apparatus to compensate for bag weight is included in the total measurement.

Abstract: A force balancing system includes a plurality of flexure elements disposed to define the corners of an imaginary parallelogram, and each being fixed at one end and connected to a movable load bearing device at the other end so that forces acting through any one flexure element are in exact balance when the system is in equilibrium. The system finds application in weighing systems wherein the object to be weighed constitutes the load.

Abstract: A filter bag tensioning device for use in a bag house is disclosed. The tensioning device comprises a straight lever arm adapted to be pivotally mounted in the upper reaches of a bag house and carrying, on the end of the lever arm opposite that of filter bag attachment, a semi-fixed counterweight. The semi-fixed counterweight is prevented from rotating as its end of the lever arm moves in an ascending direction from a horizontal position but is free to rotate as its end of the lever arm moves in a descending direction from horizontal, to thereby continuously maintain a desired design tension on an attached filter bag. In a preferred embodiment, the lever arm can also be rotated to a vertical position and then moved longitudinally of its pivot to substantially lower the filter bag attachment point, thereby greatly facilitating attachment and replacement of filter bags and, in a further preferred aspect, to permit these operations to be performed by a workman having both hands free.

Abstract: A machine is disclosed to bag powdery material wherein primary and secondary preconditioning chambers are used, having a volume sufficient to give enough time for the powdery material to become de-aerated. This de-aerated powdery material is then supplied to a bulk filling station and a dribble filling station. Bags spouted at the bulk filling station are filled to about 90 percent of their normal capacity and are then moved laterally to the dribble filling station whereat the bags are rapidly filled to a weight close to the desired exact weight and by automatic speed changing means filled to exact weight at a slower rate. The bags are supported at the top by grippers at both filling stations with the calibrated weight scale being actuated by weight on the grippers at the dribble filling station. An auger at the bulk filling station forces the powdery material down into a generally closed bag to force the bag open by the incoming material to thus keep air out of the bag as much as possible.
