[Also in Division G4] In apparatus for check-weighing and sorting, each article to be weighed is supported on an individual trolley running on a monorail. The monorail has a section 1 supported by two arms, e.g. 6, equipped with strain gauges to measure the weight. Between the weighing of successive articles, a reference weight 7c (equal to that of the unloaded trolley) is supported as shown from section 1 to calibrate the electrical weighing circuit. When a trolley enters section 1 as detected by a mechanical finger or magnetic or photoelectric means, a solenoid 9 is energized to support weight 7c off the weighing section 1. Solenoid 9 is de-energized a gain after a predetermined delay or when the trolley is detected to leave the section 1 by means similar to the entrance detecting means. The weighing circuit operates trips to discharge a weighed article at one of three stations according to whether the weight is greater than, less than or within predetermined limits. Details of the discharging mechanism, and traction means for and construction of the trolleys are as described in Specification 969,864 which is referred to. The monorail may be in the form of a single closed loop or may branch into three parallel sections.

Title: Improvements in and relating to the production of carboxylic acids
Inventor: ASHWORTH PHILIP JAMES
IPC: C07C51/15
Filed: 1959-12-31
Abstract: Carboxylic acids are produced by fusing with caustic alkali alcohol-containing residue obtained by distillation of the mixture obtained by hydrogenating the products of a carbonylation process, contacting the fused products with water to give two layers, treating the aqueous layer with carbon dioxide which liberates the carboxylic acids with more than ten carbons.  Acids with ten or less carbon atoms may be liberated by acidifying the remaining solution.  The carbonylation process consists of reacting olefines with carbon monoxide and hydrogen to give aldehydes.  The alcohol mixture is distilled and the residue, which for example may consist mainly of di-isooctylether with a mixture of C16 and C8 alcohols, is used in the present invention.  Three examples describe the production of (1) C16 and C8 acids, (2) C18 and C9 acids and (3) a mixture C14-18 acids and a mixture of C7-9 acids.  When the higher acids have been liberated by carbon dioxide, the solution may be washed to remove any occluded salts of the lower acids.  These washings may be added to remaining solution and the lower acids liberated with sulphuric acid.
