Abstract: 340,955. Glazing ceramic ware. MASCHINENFABRIK VORM. G. DORST AKT.-GES., 5, Am Edelhof, Sonneberg, Oberlind, Germany. May 28, 1929, No. 16416. Convention date, Oct. 4, 1928. Void [Published under Sect. 91 of the Acts]. [Class 56.] An airtight container 1, used in the application of glaze to ceramic objects, is filled with glaze from a vat 13 by suction. The glaze rises in the container without agitation, and the vacuum existing above the glaze extracts air bubbles. The necessary suction may be obtained by connecting the container by a pipe 7 with an aspirator 9<1> operated by a water jet 9. In another construction, the glaze is first sucked into a reservoir where it is freed from air bubbles, and is then allowed to flow into the container.
Patent GB-325764-A (GB)
Title: Improvements in or relating to screw cutting lathes and like turning engines
IPC: B23G3/04
Filed: 1929-05-29
Abstract: 325,764. Schaerer, O. May 29, 1929. Lathes.-In a screw-cutting lathe of the type wherein the work 2 rotates continuously in one direction while the lead screw 4 is reversed to return the tool between successive cuts, means operated from the work spindle are provided for ensuring that, at the end of the return movement, the lead screw reversal for a fresh cut is effected when the work and the tool are in correct phase relation. The shaft 6, which is connected to the lead screw by the usual change gears 13 .. 15 may be driven from the work spindle 1 either by the gears 8, 11 for the forward movement or by the gears 9, 10, 12 for the return movement. These gear trains are selectively engaged by means of a single-toothed sliding coupling 7 actuated by a fork 28. The fork carries a pivoted lever 17 coacting with a projection 18 on a stop rod 19 which is actuated by a projection on a cam disc 20 carried on the work spindle. Thus the shifting of the coupling 7 to re-engage the wheel 11 and start a fresh cut at the end of the return movement can only be effected at such times as the tool is in the correct position to re-engage the partly formed thread on the work. The movement of the coupling may be effected either manually or automatically. The cam disc 20 may alternatively be mounted on any other suitable shaft driven from the spindle 1, the number of cam projections being then dependent on the relative speeds of the work and cam shaft. In order to avoid shocks on reversal of the shaft 6 the lever 17 carries a cam projection 26 coacting with a similar projection 27 on a brake band 24 acting on a drum 25 secured to the shaft 6. Thus when the coupling 7 is shifted, the brake is momentarily applied to check the shaft 6 before the coupling is reengaged to effect the reversal.

Title: Composite synthetic organic textile filaments having an integral sheath-core structure
IPC: D01D5/06
Filed: 1963-04-30
Abstract: 985,717. Composite artificial filaments. MONSANTO CO. April 30, 1963 [April 30, 1962], No. 16973/63. Heading B5B. A composite artificial filament having an integral core-sheath structure comprises an inner portion or core consisting of a first polymer composition and an outer sheath portion or coating consisting of a second and different polymer composition, the outer sheath portion of the filament being integrally joined with the inner portion, and at least a portion of the second polymer composition having been precipitated within the structure of the inner portion or core of the filament. The filament may be made by extruding a solution of the first polymer composition into a coagulating bath containing dissolved therein the second polymer composition which bath comprises at least one solvent for the second polymer composition which is a precipitant for the first polymer composition to obtain a coagulated filament of the first polymer composition infused and coated with a solution of the second polymer composition, removing the solvent for the second polymer composition from the filament by subjecting the filament to a hot gaseous evaporative medium and thereby precipitating the second polymer composition partly within the inner portion of the filament and also depositing a sheath of the second polymer on the inner portion a core of the filament. The resulting composite filament is then stretched and dried. The first polymer composition and/or the second polymer may be or contain a polymer or a copolymer of acrylonitrile, vinyl acetate, and vinylidene chloride, a copolymer thereof with at least one other monoolefinic monomer, polyvinyl alcohol, a polyester, a polyolefine, a polyamide, a polyurethane, a cellulose derivative or a regenerated protein. The composite filament may have a latent reversible self-crimp and the polymers comprising the filament may shrink to different extents when the filament is heated, e.g. by treatment with a hot aqueous liquid. The second polymer component of the filament may be non-inflammable. The filament may have a high moisture regain and its second polymer component may be hydrophilic. The composite filament may have a greater affinity for dyes than a filament comprising only the first polymer and the second polymer component of the composite filament may have an affinity for dyes such as said dyes, basic dyes and dispersed dyes greater than that of the first polymer. In making the composite filament the coagulated filament consisting of the first polymer may be passed through a second coagulation bath comprising a precipitant for the second polymer to precipitate the second polymer partly within the coagulated filament consisting of the first polymer and partly in the form of a sheath or coating on the coagulated filament.

Title: Improvements in or relating to control method and means for gas turbines
Inventor: SHARP JOSEPH GOULDING
IPC: F02C9/00
Filed: 1953-06-19
Abstract: 735,213. Speed governors. SHELL REFINING & MARKETING CO., Ltd. May 7, 1954 [June 19, 1953], No. 16982/53. Class 57. Means for controlling the fuel supply to a gas turbine includes a centrifugal apparatus having a fixed outer casing 1, an inner rotor 2 situated within the casing with a radial clearance 5, and a movable member 3 carried by the rotor 2, and which, according to its position, determines the effective radius of the rotor and hence the pressure of the fuel in the clearance 5. The fuel is circulated in the clearance 5 by the member 3 which has its outer end bevelled at an angle of 35 degrees in the direction of rotation. The pressure thus established operates by way of an opening 14 on a member controlling the main fuel feed to the burners, for example a servo system, whereby the main fuel supply pump is controlled in accordance with engine speed. A shaft 9 provided with an axial fuel duct 10 connects the rotor 2 to the main fuel supply pump while radial bores in the rotor allow replacement of the fuel which leaks away from the clearance 5 to the centre of the rotor by way of the clearance at the end faces 6 and 7. The member 3 is connected to the rotor by a tension spring 4 which together with the rotor speed and the density of the fuel determines the position of the member. A decrease in fuel density reduces the pressure in the clearance 5 so that the member 3 moves radially outwards under centrifugal force to increase the speed of circulation of the fuel and hence compensate for the variation in density. Two or more members 3, circumferentially or axially arranged on the rotor, may be provided. The member 3 may also be arranged to float in the fuel, the spring 4 being dispensed with.

Title: A new or improved process and apparatus for the production of ammonium phosphates
Inventor: MALOY JOHN
IPC: C01B25/40
Filed: 1959-05-19
Abstract: In a process for producing ammonium phosphates, particularly di-ammonium phosphate, ammonia-containing vapours are distilled from ammoniacal liquor and passed at the reaction temperature (e.g. 65 DEG to 85 DEG C.) to a phosphoric acid bath maintained at the reaction temperature where ammonium phosphate crystals are produced and removed, and gases, air and water vapour are withdrawn from the bath, cooled to condense water, reheated to the reaction temperature and recycled to the phosphoric acid bath to evaporate excess water therefrom.  Ammoniacal liquor (e.g. recovered from coal <PICT:0934436/III/1> carbonizing plants) is distilled in a still 1 (Fig. 1), the vapours are cooled to the reaction temperature in a dephlegmator 2, condensates being returned to the still 1, and passed into a phosphoric acid bath 3 (pH 5,0 to 6,5).  The gases from bath 3 are partly cooled in a heat exchanger 5 by heat exchange with ammoniacal liquor being sent to still 1, further cooled in a cooler 6, condensates are removed, and a part of the gases are reheated at 8 and discharged into the phosphoric acid bath 3 through a spray ring 9.  In modifications some gases are removed from the ammoniacal liquor before it enters the still, and the hot effluent from the still is used to reheat the recycled gases.
