Abstract: Foamed articles are produced by foaming a synthetic rubber dispersion followed by gelling, vulcanization, washing and drying the foamed articles obtained, prior to vulcanization 0À1- 0À4% by wt. (referred to the rubber solids) of the sodium salt of a carboxymethylated cellulose, having an average of 0À65-2 ether groups per glucose unit, being added to the dispersion or foam produced and 0À75-2À5% of sodium silico-fluoride being added as gelling agent to the foam obtained corresponding to a gelling time of 10-30 minutes at 20 C.

Title: Method and apparatus for sheet glass fabrication
IPC: C03B15/02
Filed: 1968-09-24
Abstract: In a process for manufacturing sheet glass by drawing a continuous ribbon from the surface of a bath of molten glass wherein an upper forward current of glass flows from the melting furnace into a drawing kiln over a cooler return current flowing back to the melting furnace, the glass in the surface region flows up to the meniscus at the base of the ribbon, but the glass entering the ribbon is shielded at the downstream side of the meniscus from contact by glass which has flowed further downstream and has cooled. The shielding is done by a barrier at least partially immersed in the glass on the downstream side and which so divides the upper current whereby either only the quantity or more than the quantity of glass drawn into the ribbon flows into the region of the meniscus. In one embodiment an L-shaped barrier comprises a vertical portion 20 located downstream of the meniscus and extending transversely of the bath 3 with the upper portion above the glass surface and a longitudinal portion 22 submerged in the glass, and extending upstream beyond the meniscus. The depth of immersion is determined by the rate of draw. In a further embodiment (Fig. 4) a debitence 42 is used together with a submerged L-shaped barrier 41, 43. The longitudinal portion 43 of the barrier extends upstream beneath the debitence to the shut off 44 and has a threshold 45 on its upper surface to prevent the formation of secondary vortices. Alternatively the barrier may comprise a single vertical member partially immersed in the glass downstream of the meniscus either with or without a debitense. The barrier member is preferably heated to control the glass temperature in the meniscus region and is preferably made of an electrically conducting material, e.g. a cast alumina refractory, or may have heating elements thereon e.g. MoSi 2 . It is preferred that the upstream facing surface of the vertical member and the upper surface of the longitudinal member of L-shaped shields be platinum coated to prevent erosion and this can serve as the conducting medium. To prevent heat from the vertical member affecting the down sheet it may be capped with an insulating member 21. -

Title: Many-faceted ornamental sheet material
IPC: G02B5/08
Filed: 1968-12-13
Abstract: Ornamented material is produced by an embossing process which provides a surface of the material with an array of relief elements, which may be protuberances or depressions, arranged in rows, each relief element being contoured to have at least one light-reflecting facet, each facet of each relief element differing in contour from the facets of the next adjacent relief element, and the result being an array of highlights on the material which appear to move when any two elements of a three-part optical system, comprising a light source, the material and an observer undergo relative motion. Fig. 16 illustrates a sheet, in e.g. cotton duck, covered in a thick vinyl plastics layer, in which rows of relief elements, in the form of depressions, intersect in different orientations on the right, 14b, and left, 14a, sides of the sheet. The pattern is cyclically repeating, as shown in the row on the extreme left, where corresponding relief elements 16, 17 are separated by a plurality of relief elements having facets with different contours or orientations. Highlights 24, 25 are also illustrated, and any movement of the above-mentioned optical system will cause apparent movement of these highlights in different directions. Embossing process.-A preferred method of forming the sheets is described in the following steps:-A square tray is provided with a closepacked layer of ball-bearings thermoplastics material is poured in and allowed to set the thus-formed thermoplastics mould is electroformed, and utilized in the production of two thermoplastics plates, each of which bears a similar regular array of hemispheres on one of its surfaces (Figs. 1-5, not shown). These deformable plates are then placed with their contoured faces abutting between the platens of an embossing press, the sheets being angularly displaced with respect to each other. On the application of heat and pressure, the plates interact with each other, and deform the heat is removed and the plates are set (Figs. 6-9, not shown). They can then be electroformed to provide the embossing tools from which the ornamented sheets are produced. Alternatively, a thin sheet of paper or metal foil can be placed between the deformable plates and can be moulded by pressure alone to produce the master surface for the embossing tool (Figs. 10, 11, not shown). The different highlight effects can be produced by altering the skew angle between the plates, the direction of skew, and the contact time. The embossing press may employ rollers in place of platens.

Title: Method of Recovering Fluorine from Carbonaceous Waste Material
IPC: C01B7/19
Filed: 1969-01-30
Abstract: Fluorine is recovered from waste carbonaceous material, in the form of gaseous HF, by pyrohydrolysis in the presence of steam and air, the process being carried out continuously in a fluidized bed reactor to which solid carbonaceous material crushed to granular form is continuously added, the fluidizing gases being a mixture of air and steam. The preferred temperature is above 1100 C., and the fluidizing gases may be preheated in a heat exchanger. The heat demand comes either entirely from the combustion of the carbonaceous material or partly also from added fuel. The grain size is preferably below 10 mm. and the fluorine may be recovered from the off gas by washing with water or aqueous alkali. Disclosed is the recovery of fluorine from pot linings and pot rakings, scum and cyclone dust derived from the melt electrolytic production of aluminium. The fluorine recovered may be converted into cryolite and returned to the electrolysis.

Title: Process for dyeing cellulose fibres
IPC: D06P5/20
Filed: 1974-01-31
Abstract: The wound packages are dyed with soluble dyes or precursors for the development of azo pigments or solubilised vat or sulphur dyes at temperatures of up to 135 DEG C by the exhaust method. For this they are heated and deaerated in a dyeing vessel before dyeing and then brought into contact with the total dyeing liquor, heated separately in a make-up vessel to about dyeing temperature and put under a relative overpressure of 2.9 to 9.8 bar, by transferring the dyeing liquor from the make-up vessel into the dyeing vessel. Thereafter the dyeing treatment is completed by circulating the dyeing liquor. Immediately prior to the transfer of the dyeing liquor the wound packages are subjected to a hot steam (vapour) atmosphere at about the dyeing temperature. The dyeing liquor is then passed into the wound package, simultaneously from the inside and the outside, against the pressure of the air-free hot steam atmosphere. The dyeing process produces uniform dyeings without harming the material.

Patent ES-436757-A1 (ES)
Title: Air-hydraulic blind-riveting tool with short reset time
IPC: B21J15/00
Filed: 1975-04-18
Abstract: An air-hydraulic blind-riveting tool has a chuck which is normally urged into a ready position by a spring and which is drawn into a retracted position by a fluid-operated piston connected via a hydraulic link to an air piston subdividing an air chamber of the tool into a front and a rear compartment. The front compartment is vented to the outside and the rear compartment is connectable via a trigger-operated valve to a source of compressed air. Thus when this rear compartment is pressurized the air piston is displaced forward and the working piston connected to the chuck is retracted. A valve is provided between the rear compartment and the atmosphere which comprises a valve disk displaceable by pressure in the rear compartment against a valve seat to prevent air from leaving the rear compartment but normally urged by a relatively stiff spring away from this valve seat. Thus during pressurization of the rear compartment this valve is closed, but as soon as the pressurization is partially relieved this valve opens and allows quick return of the air piston to the ready position.
