摘要： A sheet assembly comprises a first grid comprising a first plurality of shapes on the sheet and a second grid comprising a second plurality of shapes on the sheet. The second plurality of shapes overlay the first plurality of shapes such that the second plurality of shapes are in a center of one or more squares defined by the first plurality of shapes. The first grid in combination with the second grid creates a template for the creation of one or more discrete components such as a list, a table, a chart and a graph. In some embodiments, the first grid comprises a plurality of crosshair shaped plus signs and the second grid comprises a plurality of dots. The two grid patterns are overlaid and offset from one another. The two patterns are offset such that the dots are located at the center of the squares defined by the crosshairs.

摘要： A method of production of a product from a stock pulp sheet uses conveyor rolls to convey a stock pulp sheet to a crusher. During conveyance to the crusher, a defective part in the stock pulp sheet is detected by a detector. The detected defective part is removed from the stock pulp sheet by a remover. The stock pulp sheet from which the defective part is removed is supplied to the crusher to produce crushed pulp. The produced crushed pulp is used to produce a product in a product producer.

摘要： A process and an installation for drying cellulose materials. The invention consists in placing the materials in a vacuum-tight enclosure, bringing the materials in contact in vacuo with ethylene glycol diacetate injected into the enclosure after having been dried and heated initially to a temperature of from 60* to 70* C and which is raised gradually during drying to a steady end value of from 100* to 110*C, maintaining a vacuum equal to the ethylene glycol diacetate vapour pressure in the enclosure throughout drying, drying the ethylene gylcol diacetate from the enclosure by exhausters, and condensing and filtering the recovered ethylene gylcol diacetate for reinjection into the enclosure, the cycle just described being repeated until the cellulose materials are completely dry.
