Title: Improvements relating to the tempering of glass articles
IPC: C03B27/012
Filed: 1965-06-27
Abstract: <PICT:1104449/C1/1> A process for tempering glass articles, particularly sheets of flat glass, comprises moving the suspended sheets 1 through a tunnel 2 in which they are pre-heated, e.g. by radiant heaters 11 and thereafter transferring the sheets into a chamber 4 where they are first raised to the tempering temperature, e.g. by high-frequency induction and then rapidly cooled to below the lower limit of tempering. The sheets pass between piston-operated doors 3 into the chamber 4 wherein electrode 12, which may be pivotal through 90 degrees, or fixed electrodes with passages therebetween are mounted.  At the required temperature the heating is switched-off and cooling air is blown on to the sheet from nozzles 16, the air jets passing between the electrodes. Preferably the jets have a gyratory motion to give more uniform tempering.  In an alternative embodiment (see Fig. 6, not shown), the cooling boxes from which the jets emanate may also form bending platens for the glass sheets.  The heating electrodes may be placed right up against the glass surface and collectively have a shape corresponding to that of the glass sheet.

[Class 120 (iii)] [Also in Group XXV] Yarn is produced from glass or artificial mineral fibres by feeding the fibres F on to the exterior of a rotating cylindrical shell 10 so forming an interlaced mass or fibrous web 18 which is withdrawn endwise in tubular form and passed as a core axially through a second rotating shell 10 from which it receives a covering of a web 19 consisting of similar fibres F. The shells 10 are driven by motors 12 and are mounted above suction boxes 13 with perforated covers so that air is drawn round the shells to assist in laying the fibres. A yarn or a conducting wire 17 may be passed through the hollow shaft of the first rotating shell 10 and is drawn off with a covering formed by the web 18, and another covering can be provided by the second rotating shell. The direction of rotation and the speed of the shells may be varied. In a modification the suction box is arranged around the hollow shaft and the nose part of a shell is secured to the main part by screwing. The modified form 10a of rotating shell shown in Fig. 4 has a hollow shaft 16 provided with a feed pipe 28 for compressed air or other gas which conveys a lubricating, gluing or impregnating agent. This stream passes from the end of the shaft through the opening 23 in the nose of the shell, so that it acts efficiently on the yarn or wire passing through the shaft and on the interior of the fibrous tube 29. In another modification the walls of the shaft and shell are perforated to permit the passage of the compressed air stream. The finished yarn or insulated conductor is passed through a hole in a rotating disc 34, Fig. 8, and then between two adjustable grooved rollers 36 mounted on the disc ; this smooths the outer surface of the coverings.

Title: Improvements in or relating to the extraction of fats or oils from animal sources
IPC: C11B1/10
Filed: 1950-10-13
Abstract: In processes for dehydrating or defatting animal materials in a heated bath of oil or fat, the fat or oil produced being separated from the residual animal materials, the latter are solvent-extracted to recover remaining fat or oil therein, and the miscella obtained is returned to the initial dehydrating or defatting stage.  The process avoids the necessity of removing the particles of animal matter in the miscella, the fat or oil drained off from the initial dehydrating stage being free from suspended matter.  The solvent returned to the initial stage is recovered therefrom by evaporation together with the water produced, the vapours being passed to a condenser and the solvent separated for re-use.  Although it is preferable to return the solvent extract to the initial stage so that a separate solvent recovery apparatus may be dispensed with, the solvent may be recovered separately and the residue of fat or oil and suspended matter returned to the initial stage.

Title: Device for unloading the stored momentum of a space vehicle
Inventor: DAVIS LOUIS KEITH
IPC: B64G1/28
Filed: 1966-06-06
Abstract: 1,133,605. Controlling space vehicles. GENERAL ELECTRIC CO. 6 June, 1966, No. 25133/66. Headings B7C and B7W. [Also in Division H2] A device for unloading stored angular momentum against the constraint of an external magnetic field, in particular for stabilizing a space vehicle, comprises a spherical body 26 free to rotate within a cavity in a housing 10, the space in the cavity between body 26 and the housing being filled with a fluid which communicates with closed conduit circuits 28, 32 and 36 respectively associated with pumps 30, 34 and 38 selectively energized by a pump drive and control unit 40. The body 26, Fig. 3, comprises two hemispheres of aluminium joined by an internal screwed ring 50, a plurality of horseshoe magnets 52 being arranged within the body whereby a locally intense magnetic field is produced which interacts with a diamagnetic liner 58 in housing 10 whereby the body 26 is held centrally within the cavity in housing 10. A bar magnet 56 is positioned between poles of the spherical body to produce an external magnetic field of sufficient intensity to extend beyond the housing 10 to interact with the ambient magnetic field 57 e.g. of the earth to set up resistance to torques tending to rotate the body. In operation, and selecting one fluid circuit e.g. circuit 36, if a vehicle in which the device is installed has been subjected to angular momentum and equilibrium has been achieved by circulation of fluid in conduit 36 then angular momentum will be stored in the circulating fluid about an axis normal to the plane of the conduit. The circulating fluid will inter-act with the fluid 60 in the cavity between body 26 and housing 10 to tend to cause body 26 to rotate about said axis. Such rotation will tend to be restrained by inter-action between the magnetic field of magnet 56 and the ambient field 57 and this will result in retardation of flow within circuit 36 and transference of its angular momentum to the mass e.g. the earth, which is the source of field 57. In a further embodiment mechanical flywheels are used to store energy.
