Patent GB-449255-A (GB)
Title: Preparation of granulated and reversible rubber composition from rubber latex
IPC: C08C3/00
Filed: 1934-12-18
Abstract: Granulated rubber is made by flocculating rubber from an aqueous dispersion, removing water until a mass having a water content of 25-45 per cent is obtained, and granulating this mass. A stabilizer, preferably in amount not exceeding 7 per cent of the solids of the dispersion, may be added, this stabilizer being preferably one which is rendered insoluble by the flocculating agent used, e.g. glue with formaldehyde, casein with zinc salts. Suitable flocculating agents are soluble salts of magnesium, calcium, zinc, aluminium, lead. Acids and acid salts are less suitable, as it is desirable that the pH value of the flocs is not less than 7.  The partially dewatered cake is granulated to a fineness of 20 mesh or more, this being assisted by the addition of 1-2 per cent of talc, zinc stearate, or the like.  The granulated rubber may be dried without cohering.  The granulated rubber may be moulded under heat and pressure, and may be mixed with compounding ingredients, and used as a vehicle for introducing these into rubber batches as described in Specification 449,165.  The addition of ammonia water causes redispersion as in Specification 449,056.  Fibres, abrasive grains, and the like may be added to the granules.  Matt surfaces may be obtained by applying the granules to rubber or other surfaces.  Specifications 327,451, [Class 70], and 410,793 also are referred to.

Title: Improved method of drying wet materials
IPC: F26B5/04
Filed: 1929-11-27
Abstract: 343,981. Drying wet materials. AKTIEBOLAGET FRIBERG'S HÍGVACUUMPUMP, 8, Artillerigatan, Stockholm. Nov. 27, 1929, No. 36372. Convention date, Nov. 29, 1928. [Class 34 (ii).] In a method of drying wet materials in which the materials are dried in a closed chamber by alternately heating directly with steam and subsequently evacuating the chamber, the materials are first heated at atmosphere pressure while the air is being expelled from the drying chamber which is then evacuated and the subsequent heating steps are carried out in the absence of atmospheric air, a pressure below atmospheric pressure being maintained in the chamber until the desired dryness of the goods has been attained. The pressure during the subsequent heating steps is carried out at a pressure below 200 mm. of mercury and is cut off when the temperature of the material is raised to 60‹ C., the evacuation then being continued until the temperature falls to about 35-40‹ C. Superheated steam may be used for heating the material.

[Class 97 (i)] In a spectacle lens having two fields of which one at least has a factor compensating for the different sizes of the images formed by the two eyes, one of the fields extends beyond and acts as a support for the other field. In Fig. II the one field 6 surrounds the other field consisting of two elements 4, 5, the element 4 being an ordinary lens for correcting refractive errors and the element 5 being for the purpose of correcting for the said size differences. The member 6, which may or may not have optical power, acts as a spacing member between the elements 4, 5 to which it is cemented &c. and may be shaped for insertion in the rim of a spectacle frame. In Fig. III the lenses 4, 5 are combined to form a single lens 7 effecting both the corrections referred to, and the supporting field 6 is formed integrally with the lens 7. The field 6 may however be formed separately and the lens 7 may be recessed to receive it. In Fig. V, an additional lens element 11 has been added to the form shown in Fig. II, and is spaced from the lens 4 by a separator 12. The corrective lens may occupy the lower or any desired portion of the entire field instead of being disposed centrally as shown.

Title: Method of removing oxygen from oxygen-contaminated material comprising mainly transition metals of the 4th, 5th and 6th groups of the periodic table
IPC: C22B34/00
Filed: 1954-12-29
Abstract: Oxygen is removed from oxygen-contaminated material comprising mainly transition metals of the 4th, 5th and 6th Groups of the Periodic Table by adding boron and melting the material under vacuum or in an inert atmosphere.  The melting may take place in an electric arc furnace in which the electrode is of tungsten or comprises the metal or alloy to be treated with the boron addition.  In the latter case the electrode is consumed by melting as the arc burns.  The inert atmosphere may be provided by a flow of noble gas.  The boron may be used in the form of diborides of the said transition metals or as calcium boride or boron carbide or mixtures thereof.  Where iron is required to be introduced into the transition metal ferro-boron may be used.  Reference is made to treatment of an alloy containing up to 30 per cent of one or more of Cr, Mo, W, V, Fe, Al, Mn, the remainder being titanium.

Abstract: 1417470 Wells &c McEVOY OILFIELD EQUIPMENT CO 16 Aug 1973 [1 Sept 1972] 38783/73 Heading E1F In wash apparatus for controlling the passage of washing fluids between the flowbore and surrounding annulus of a casing following cementing, there is provided a lower tubular member 30 for suspending a casing string 22 in a well, an upper tubular member 40 rotatably mounted within the lower member 30 and adapted for connection to a casing extension or riser 21, a fluid passageway 112 in the lower member for effecting communication between an annular space between the upper and lower members and a surrounding annulus 28, and sealing means within the annular space, the arrangement being such that rotation of the upper member in one direction relative to the the lower member brings the flowbore into communication with the annulus 28 via the annular space and passageway 112, and further rotation of the upper member in the same direction terminates such communication. In a first embodiment (Figs. 3 to 5 not shown) the upper member 40 is axially displaced during rotation and is provided with circumferentially spaced ports (114) which are brought into registration with ports 112 in the lower member to provide the communication.

In an alternative embodiment (Figs. 6 to 8 not shown) the upper member (230) is prevented from axial displacement and threadably engages a valve sleeve (210) which is prevented from rotating. Rotation of the upper member axially displaces the sleeve into the communicating position wherein fluid flows through the open end of the upper member (230), and then into the non-communicating position wherein this fluid flow is blocked by a compression seal (320) carried at the lower end of the valve sleeve (210).
