Patent IE-59437-B1 (IE)
Title: Sleeve-type carrier with improved handle
IPC: B65B/
Filed: 1986-10-29
Abstract: A carrier (10) having a handle opening (30) in the top panel (14) extends transversely of the length of the carrier (10). The handle opening (30) is covered by a tab (68) connected at a fold line (76) extending along one of the handle opening edges. The tab (68) has an intermediate fold line (74) parallel to fold line (76), enabling the tab (68) to fold upon itself. Slits (32, 34) extending from the ends of the handle opening (30) into the upper portions of the side panels (12) allow the top (14) and side panels (12) to flex sufficiently to permit the carrier to be lifted by the handle opening (30). Score lines in the upper portions of the side panels (12) extending upwardly from the ends of the slits (32, 34) to relieve the stresses exerted on the panels when the carrier being lifted. Score lines (36, 38, 40, 42) allow the upper panel (14) to withstand lifting stresses to the extent that thinner carrier material can be used.

Abstract: A reagent strip for measuring glucose concentration in whole blood has reduced interference of hematocrit with the glucose measurement. When a biological fluid contacts the strip, it causes, in a reagent impregnated in the strip, a color change that is a measure of the glucose concentration in the fluid. However, the color change is also affected by the red blood cell concentration (hematocrit), thereby reducing the accuracy of the glucose measurement. The hematocrit effect is reduced by adding to the reagent an acrylic acid polymer.

Patent BR-0009097-B1 (BR)
Inventor: ROSENBERG STEVEN PHILIP
IPC: C01F7/473
Filed: 2000-03-17
Abstract: A process for the removal and causticisation of sodium oxalate and/or sodium sulphate from a Bayer process liquor containing sodium carbonate and one or both of sodium oxalate and sodium sulphate in an alumina refinery is described. The process is based on the observation that to efficiently causticise sodium oxalate solutions, it is first necessary to remove the aluminate ion from solution, optionally with recovery of the aluminate ion in some later step. This is effected by removing aluminate ions from the Bayer liquor through the formation of a carbonate bearing hydrocalumite and/or sulpha-bearing hydrocalumite. The liquor may then be treated with sufficient lime to remove and causticise any residual carbonate ions and some or all of the oxalate ions present so that any reacted lime solids thus formed can be separated and safely disposed of. The process may include a pre-causticisation step in which the Bayer liquor is first causticised to reduce the concentration of carbonate ions, prior to the step of removing aluminate ions. The invention provides an effective process for the removal of sodium sulphate and a practical method for the recovery of soda from sodium sulphate. The efficiency of lime utilisation can also be dramatically increased from about 20% to 80% (if sulphate removal is not the objective) wherein alumina losses can be minimised. The oxalate concentration of the process liquor is also substantially lower than can usually be achieved in processes based on sodium oxalate-crystallisation.
