Title: Weighing machines
IPC: G01G13/00
Filed: 1950-04-18
Abstract: 697,960. Automatic feed weighers. WRIGHT MACHINERY CO. April 18, 1950 [Dec. 12, 1949], No. 9516/50. Class 143 In an automatic feed weigher the weighed charge is discharged from the pan by a mechanism which is normally disengaged from the pan but which, at the end of each weighing cycle, grips the pan, lifts it off the weighing mechanism and tilts it into a dumping position. The pan has two pairs of trunnions 26, 94, Fig. 3, the lower pair of which, 26, normally rest on a cradle 20 which is supported on a pre-loaded float balance 14 and, when the weight of material in the pan depresses the float, a cam 78 is rotated through one revolution so pivoting a pair of levers 70 first to the right, as viewed in Fig. 1, and then back to the position shown. This movement is communicated through a pair of links 60 to a pair of blocks 48, see Fig. 3, each of which is pivoted at 52 to an L-shaped block 34, in turn pivoted to a fixed frame 12 at 36. The blocks 34, 48 are urged to pivot into engagement with trunnions 26, 94 by a spring 88, but are normally maintained free thereof, in the position shown in Fig. 3, by the engagement of blocks 34 with rubber pads 87 secured to members 12, and by the cam 78 which locks the links 60. However, when said links 60 are moved to the left, as viewed in Fig. 3, the blocks 48 pivot about axis 52 so lifting the lower trunnions 26 on seats 22 and engaging the upper trunnions 94 with seats 44 secured to the block 34. Thereafter the pan, gripped between pairs of seats 22, 44 by the action of springs 88, is pivoted, together with blocks 34, about axis 36 into a dumping position. After discharge the cam 78 effects a reverse action to return the pan to the weigher. Specifications 638,665 and 666,306 are referred to.

Date Mar. 24, 1988.Method for cleansing gas from solid, liquid and/or gaseous contaminants, by bubbling the gas through a liquid bath (32), and by introducing the incoming gas into a distribution means (14) and causing the gas to pass in part-streams through a multiple of inlet orifices (64) located at progressively increasing depths beneath the surface (34) of the liquid (32). With increasing inlet pressure an increasing number of inlet orifices (64) are utilized for an increasing number of part-streams. The gas flow is passed from respective inlet orifices (64) through connecting means (24, 26, 28) to outlet orifices (31) located at a considerably higher height level (h) than corresponding inlet orifices (64). The gas flow is caused to flow out through venturi nozzles (28) and/or to strike against impinger or striking surfaces (39) with a minimum pressure drop corresponding to said height differential (h). In this way full operational pressure is immediately achieved, as soon as gas is passed out through any of the inlet orifices (64), and an intense mixing of gas and liquid as well as a high cleansing efficiency are guaranteed.
