Title: Improvements in coating porous materials
IPC: B32B27/00
Filed: 1958-01-27
Abstract: 864,309. Laminates; coated fabrics. RIEGEL PAPER CORPORATION. Jan. 27, 1958 [Feb. 18, 1957], No. 2693/58. Class 140. [Also in Group XVII)  A porous coated product is made by taking a laminate which includes two layers of base web material, at least one of which is porous, and an intermediate layer of normally non-porous material which is heat-softenable at a temperature that does not adversely affect the porous base material, the intermediate layer being bonded to the layers of base web material with a bond strength greater than its own cohesive strength when it is in the heat-softened state, and separating the two layers of base web material while the intermediate layer is in its softened state, so that the intermediate layer is split along a centre plane to render the intermediate material porous through to the base material. As shown, a web 11 of polyethylene is extruded between two webs 15 and 16 of porous paper of high wet-strength, passing through the nip of two rolls 13 and 14. The roll 13 is of metal, hollow, and cooled internally, e.g. by water. The roll 14 has a metal core and an outer elastomeric layer. The laminated web 17 from these rolls passes round an idler roller 18 to the roller 19. This roller is one of a pair, 19 and 20, of rollers heated internally, as by steam, to about 300-400‹ F., and urged together, as by springs 2], 22. In passing round the roller 19, the polyethylene is softened, and in the nip between rollers 19 and 20, it is squeezed into the porous paper layers. These two layers are then delaminated by passing them on either side of the bar 24, cooled and rolled up separately at 26 and 27. The finished product is heat-sealable, and suitable for making tea-bags. The method may also be used to coat other porous materials, e.g. textile fabrics, with other heat-softenable materials. Heavy-duty work gloves may be made from canvas cloth coated with nylon by this method.

Title: Method for the removal of fluorine from industrial gases
IPC: B04C9/00
Filed: 1954-02-08
Abstract: Calcium fluoride and silicofluoride are formed in the removal of fluorine and gaseous or solid fluorine compounds from industrial gases by adding calcium oxide, hydroxide or carbonate (collectively referred to as "lime") to a stream of the gases, subjecting the lime-containing stream of gases to vortical action, skimming off a portion of the gases containing a higher concentration of particulate matter, returning said portion to the limecontaining stream of gases, and separating solid matter from the remaining portion of the gases subjected to vortical action, e.g. by electrostatic precipitation. Particularly when the gases arise from a sintering machine (e.g. of the pallet type used for sintering ferrous ores in admixture with coke, flue dust and limestone) and a portion e.g. 40 per cent of the gases is recirculated through said machine, coarser suspended particles may be separated from the lime-containing stream of gases, and recirculated with, if desired, additional lime.  Suitable apparatus for producing vortical action is described and claimed in Specification 727,704 [Group II] to which the present Specification bears reference.
