Filed: 1932-05-24
Abstract: 402,099. Ventilators. WASSMUTH, KURTH, & CO. AKT.-GES., 19, Grafenrn³hlenweg, Dellbruck, Cologne, Germany. May 24, 1932, No. 14763. Convention date, Jan. 13, 1931. [Class 137.] A distributer for the delivery of air to a room without draught of the type comprising a set of partitions arranged to provide between them throughway passages which increase in area from the inlet to the outlet, the partitions being connected together to permit them to be angularly adjusted as a unit relatively to the inlet conduit, is provided with a connection between the inlet conduit and the inlet end of the set of partitions whereby all the air issuing from the conduit is directed into the passages between the partitions in any angular position of the latter. In the form shown the connection comprises a spherical member d attached to an annular plate b at the mouth of the conduit a and a second spherical member f attached to the set of partitions L and rotatably mounted within the member d. In a modification, to ensure distribution without draught when the partitions are in their normal position, that is when the axis of the partitions is in alignment with the axis of the conduit, the innermost passage is provided with a valve in the form of a pivoted disc u. In the normal position, the equal air pressure on both sides of the axis of rotation of the disc keeps the passage closed. As the partitions are angularly displaced, the air pressure on the sides of axis of rotation becomes unequal and serves to turn the disc and thus allowing the passage of air through the inner member. The valve may be caused to open as the partitions are moved, by means of a system of links.

The container 5 is adapted to support a bag having its upper end fitted over a filling nozzle which is coupled to a source of material. Supply by a flexible coupling 8. The load cell comprises a stacked series of annular segments 40-47 which contain a force transmitting-rod 48 which is composed of a series of stacked segments 49-56 and co-operates, by means of a ball bearing 57, with cross beam 33 of the bracket 30, the ball 57 being retained by a washer 92 suspended by a series of chains 94. The load cell also includes a series of flexible diaphragms 60, 61, 66, 69, 72, 74, 77 which extend respectively between the annular and stacked segments 40-47 and 49-56. The cavity 62 formed by the diaphragms 60, 61 is fed with pressurized air through a pipe 63 and regulator 64, the effective area of the diaphragm 60 being greater than that of the diaphragm 61 to provide an upwardly acting-force to compensate for the tare weight of the container. The third diaphragm defines a second cavity 67 which communicates with the atmosphere through a pipe 68. A fourth diaphragm 69 having a smaller effective area than the diaphragm 66 provides a third chamber 70 which communicates with the vacuum environment in the housing 2 through ports 71, the vacuum acting upon the diaphragms 66, 69 providing a downward force exactly equal and opposite to that provided upwardly on the diaphragm 60. The oil-filled chambers 73, 75 formed between the diaphragms 69, 72, 74, provide, with ports 76 through the diaphragm 74, a dashpot to damp the movements of the rod 48. A cavity 78, between the diaphragms 74, 77 communicates with the atmosphere pipe 68. Pressure from a conduit 88 having a pressure and constant flow regulator 89 is supplied to a lower cavity 87 until the pressure therein balances the load on the cell 23 whereupon a plate 84 lifts off an orifice 81 leading to atmosphere and the pressure is stabilized and transmitted, through a conduit 90, to the recorder 38 which may have a connection to conventional control means to effect the automatic termination of filling. The container 5, which preferably has adjustable side walls to conform to the shape of the bag being filled, has a front and side walls 11, 12 pivoted at 13, the housing 2 having a front panel 20 which is pivoted at 22.
