IPC: G01G23/37
Filed: 1990-08-20
Abstract: A load cell weighing device has a plurality of load cells (1a-1d). In the device, detection values are respectively output from the load cells (1a-1d). The detection values are digitized by analog-to-digital conversion circuits (3a-3d). Low frequency noise compo­nents involved in the digitized detection values are reduced by digital filters (21a-21d). Then, the noise-­reduced values are summed to provide weight data.

IPC: C10M175/00
Filed: 1990-10-10
Abstract: In a process for treating used hydraulic fluids based on glycol ethers having a substantial content of borates of glycol ethers, the hydraulic fluid to be treated is heated with an excess of at least 38% by weight of one or more short-chain aliphatic alcohols, relative to the amount required for the stoichiometric transesterification of borates of glycol ethers, at atmospheric pressure or at elevated pressure at a temperature at which transesterification of the borates of glycol ethers proceeds to give trialkyl borates and glycol ethers. The trialkyl borates have a markedly lower boiling point than the glycol ethers present in the hydraulic fluid and formed in the transesterification, and can thus be separated from these by fractional distillation. The process delivers purified glycol ethers and highly pure trialkyl borates, which can either be reacted by back-esterification with glycol ethers to give borates of glycol ethers and mixed with glycol ethers to give hydraulic fluids or further processed to give pure borate esters and/or pure boric acid.

Abstract: A method is described of producing from deformable plastic a package (1) comprising tube (3), bottom and upper wall (2) and filled with a flowable material, in which method the package (1) formed by deforming and the effect of heat is filled, closed and conveyed away. 
<??>To provide an environmentally friendly method of production, in which a package can be produced by thermoforming without significant waste, the invention provides that two blanks (4) respectively in the form of a flat sheet are heated at a distance from each other (in III-V), then brought together along a frame-shaped strip (7-11) and welded by thermoforming (in V) of the central region (12) within the frame-shaped strip (10) to form the package volume, an opening (13) being provided in an upper wall (2), the package (1) thus formed and impervious to the flowable material, with the exception of the opening region (3), being cooled, further conveyed (18-20), filled (in XI) and closed by an opening piece (14) covering the opening (13).
