Filed: 1972-02-21
Abstract: 1362891 Blasting R E ECKELS 21 Feb 1972 [22 Feb 1971] 7899/72 Heading E1F A method of blasting material involves placing a selected pattern of explosive charges adjacent to or against the surface of the material to be blasted and detonating the charges. Preferably the charges are secured in the selected pattern to an expendable frame or to a series of expendable, interconnected frames. For positioning the frame(s), the frame(s) may be supported from one or more hoist ropes, which are paid out to lower the frame(s) into close proximity to the material. Accurate positioning of the frame(s) over the material is by controlled positioning of the substantially vertical hoist rope(s) by means actuated from points remote from the material before the frame(s) is or are lowered into contact with the material and the charges detonated. This method of positioning the frame is of use in the blasting of exposed or underwater rock. Alternately in the blasting out of ditches the charges are positioned substantially level when adjacent the material in which the ditch is to be blasted so that a level ditch can be formed as charges in contact with or adjacent raised material will break the material deeper.

Abstract: 126,174. Cross, C. F., and Bevan, E. May 17, 1918. Pulp, preparation of; parchment paper. - Fibrous cellulose substances, such as cotton, flax, hemp, esparto, jute, wood cellulose, pulp for paper-making, yarns, and fabrics, are treated to form hydrated cellulose derivatives while retaining the fibrous structure by subjecting them to the action of alkali dye of strength insufficient to produce mercerization (in the case of caustic soda 6-11 per cent. strength) and simultaneously or subsequently to the action of carbon bisulphide. After some hours, the substances are washed with water to remove alkali and to develop hydration effects which are shown by a swelling of the fibres and exaggeration of the central canal of the fibres. Alkali may be removed by washing with a solution of neutral alkali salt such as brine and the hydration effected subsequently by treatment with water. A final treatment with dilute acid may be carried out. If the treatment with alkali be carried out at an increased temperature (80-90‹ C.) a product is obtained which, when subjected to pressure, yields a parchmentlike material.

Abstract: 1357992 Spinning yarns E I DU PONT DE NEMOURS & CO 23 Feb 1972 [23 Feb 1971] 8394/72 Headings D1F and D1W A fasciated yarn comprises a core of discontinuous organic fibres bound together by discontinuous organic fibres disposed as an irregular helical wrapping therearound and exhibiting a shrinkage differential of at least 5% and a standard deviation in short-term shrinkage variability of at least 2.8. The yarn is prepared by forming e.g. by successive doubling and drafting, a strand of blended organic fibres of which a minor proportion e.g. 1-40% by weight, are relatively high shrinkage fibres, drafting the strand to form a flat untwisted bundle, removing this from the front draft rollers by an aspirating fluid jet and false-twisting it e.g. within a torque jet, into a yarn. The yarn is incorporated into a fabric which may be subjected to shrinkage treatment to produce crepe effects therein resulting from differential shrinkage of the yarn fibres: alternatively, the fabric may be finished flat, heat-set and hot-calendered to produce a smooth fabric. Suitable high and low shrinkage fibres, which may be of similar or different polymeric composition, include polyamides, polyesters, polyacrylics, cotton, wool and bicomponent, mixed polymer and/or blended forms thereof and may vary in length: the yarn may incorporate one or more continuous filaments. According to a described test, yarn shrinkage differential is the difference between calculated percentage shrinkages based on length measurements of a sample skin under light, and then heavy, load before and after relaxation under no load, and is effective to detect the presence of relatively high shrinkage fibres in the yarn and provide indication of the concentration thereof. In a shrinkage variance test, standard deviation of a yarn is calculated from measurements of straightened segments before and after a heat-setting, fibre shrinkage treatment with steam at 240‹F for four minutes.
