Patent GB-350472-A (GB)
Title: Improved manufacture of rubber compositions
IPC: C08L81/00
Filed: 1930-03-05
Abstract: Rubber is compounded with an ethylene polysulphide plastic, such as is derived from the reaction of a polysulphide with an olefine dihalide as described in Specification 302,270, [Class 70, Indiarubber &c.], in the absence of free sulphur, and the mixture is vulcanized by heat.  The soft plastic, containing 70 per cent and upwards of combined sulphur is preferred.  The proportion of rubber may vary, the higher the percentage the more nearly does the compound approach vulcanized rubber in tensile strength. Fillers, pigments, accelerators may be added.  Several examples of proportions, ingredients, &c. are given in the Specification.

Title: Apparatus for exposing sheet materials to radiation
IPC: G03B27/30
Filed: 1961-03-01
Abstract: 984,226. Irradiating sheet material. MINNESOTA MINING & MANUFACTURING CO. March 1, 1961 [March 28, 1960], No. 7477/61. Heading B5B. [Also in Divisions B6 and H5] Apparatus for exposing sheet materials to intense radiation includes a source of radiation and a movable porous support against which the sheet is held for exposure by the maintenance of a partial vacuum on the further side of the support; the apparatus may be applied to the fusion of a rough thermoplastic coating into a smooth layer, or to the production of high, graduated relief patterns on inked sheets, in which the inked pattern absorbs radiant energy and heats a layer of heat-softenable material containing a heat-sensitive blowing agent included in the sheet, whereby the layer is caused locally to expand. A tungsten filament gas-filled infra-red lamp 10, Figs. 1 and 3, is mounted in a reflector 11 provided with fins 13 above a rotatable perforated cylinder 12, covered with a porous woven glass fabric 29, on to which the sheet for treatment is fed from guide surface 30. Within cylinder 12 is a non- rotatable housing 18 provided with grooves 23 and apertures 21 in its top wall, which is held against the inner surface of cylinder 12 by springs 27, Fig. 3, extending between the housing and the perforated, non-rotatable cylinder 19, on the ends of which the driving wheels (Figs. 2 and 4, not shown) for cylinder 12 are mounted. The end of cylinder 19 is connected to a vacuum line, whereby the interior of housing 18 is partially evacuated to maintain by suction a sheet of material fed from guide 30 against the fabric 29 over that region of the cylinder lying above apertures 21. The hubs of the driving wheels for cylinder 12 are apertured to enable air to be pumped into annular region 32 whence it escapes through cylinder 12, and is drawn by exhaust fans through housing 31, helping to loosen the sheet of material from the latter subsequent to its passage beneath the lamp, and cooling the cylinder 12, the return guide 33 for the material, and the lamp, its fins, and reflector. Instead of glass fabric, cylinder 12 may be covered with a flocked or wire material; a continuous belt may be employed instead of cylinder 12; and housing 18 and tube 19 may form an integral unit, or tube 19 may be dispensed with at the cost of less uniform withdrawal of air throughout the length of the housing. Specification 860,437 is referred to.

Patent GB-453504-A (GB)
Title: Improvements relating to the after-treatment of thread windings of regenerated cellulose
IPC: D01D10/04
Filed: 1935-03-11
Abstract: Cakes or other windings of artificial silk or other regenerated cellulose threads are dried and then remoistened so that the moisture content is from about 20 per cent to about 50 per cent, and the windings are then dried again in such way that the inner thread layers are able to shrink.  The process may be applied to threads obtained by the viscose process and particularly to cakes of thread which have been loosened during washing.  Moistening may be effected by putting the windings in chambers in which appropriate conditions of humidity and temperature prevail.  The windings may be surrounded individually or in groups with a cover of cambric or similar material and wet steam at 35--60 DEG  C. may be introduced into the inside. Wet steam may be introduced to the inside of a column of superposed windings.  If the windings are on bobbins or other rigid supports during the first drying, they are removed before the second drying. As shown, dried cakes a are loosely mounted on carriers b and arranged to form a column closed by cover <PICT:0453504/IV/1> c.  The column is loosely surrounded by a cambric sleeve d.  Steam is blown through pipe e into the column of cakes, the moistening treatment being continued for several hours.  The cakes are then dried again in such a way that the inner thread layers can shrink. Specifications 344,279 and 358,151 are referred to.
