Title: An improved method and means for coating metal articles with zinc specially applicable to coating metal window frames
IPC: C23C2/06
Filed: 1935-08-09
Abstract: Metal articles, for example iron window frames, are coated with zinc by first dipping into molten zinc, then heating out of contact with oxygen or other injurious substance for a time and at a temperature sufficient to cause the coating to form an alloy with the base metal, and finally, without allowing the article to come into contact with oxygen &c. re-dipping it while still hot in molten zinc.  In the preferred form the article is passed through a layer of molten zinc into molten lead, is kept in the molten lead, which is heated to a high temperature, e.g. 550-570 DEG  C., for a time sufficient to cause the alloying, and then withdrawn through the zinc.  The article must remain in the lead for a sufficient time to raise its temperature to 490 DEG  C.  The bath preferably has downwardly tapering sides.  the furnace being arranged on the sides so that the heat is distributed over a wide area of the bath.  The zinc may if desired be contained in a shallow retaining frame so that it does not come into contact with the walls of the bath.  Specification 2389/15, [Class 82 (ii)], is referred to.

Patent GB-669518-A (GB)
Title: Process for the recovery of fluorine from effluents
IPC: C01B33/10
Filed: 1950-09-14
Abstract: Fluorine is recovered from effluents, e.g. gases containing silicon tetrafluoride, hydrofluosilicic acid and hydrofluoric acid derived from various industries, by passing the effluents into contact with a bed of crushed mineral magnesium silicate, e.g. forsterite olivine, steatite, serpentine &c.  The latter hydrated forms should first be calcined.  A solid mixture of magnesium silicofluoride and silica may be collected by vibrating the charge, or the material may be leached, or sufficient water may be sprayed through the charge during reaction to produce a solution of magnesium silicofluoride, which may be purified from iron by the addition of magnesia, and crystallized. Alternatively, the effluent gases may be dissolved in water, and the mineral treated with the acid solution obtained.  The crystallized silicofluoride may be distilled with concentrated sulphuric acid to produce hydrofluoric acid; if the silicofluoride is not first dehydrated, the gases are dehydrate by hot concentrated sulphuric acid.  Magnesium sulphate is recovered by crystallization. Alternatively, the magnesium silicofluoride may be treated by the process of Specification 669,519.

Title: An apparatus for melting powdered material by means of a flame
IPC: B01J6/00
Filed: 1961-06-22
Abstract: In the production of monocrystalline bodies from powdered corundum or spinel, the powder is fluidized in an oxygen stream which entrains a portion of the powder and the suspension is mixed with a combustible gas and burned in a plane to build up a boule of the material on a support which is slowly withdrawn. The oxygen flow rate is adjusted to <PICT:0980495/C1/1> maintain the rate of growth constant.  As shown in Fig. 1, the burner comprises an inner tube 1 and an outer concentric tube 2 to which a combustible gas is admitted through a conduit 3 controlled by a regulator 4.  The inner tube is connected to a chamber 6 to which oxygen is admitted by a conduit 40 at a rate dependent on the setting of a valve 8. The chamber 6 is also connected by a sleeve 12 to a powder dosing device 11 having a porous plate 15 of sintered glass on to which powder is fed from a conduit 16 and through which oxygen passes from a space 14 supplied from a conduit 9 at a rate dependent on the setting of a valve 10.  The valves 8, 10 are moved by a common actuating mechanism 28 so that the sum of the flows through the valves is constant. The flame 18 produced by the burner entrains particles which are deposited on a deposition surface 19 as a gradually growing rod 22.  The deposition surface is moved vertically at a constant speed by a rack and pinion 20, 21. The light emitted by the most recently precipitated molten material is sensed by a photo-cell 24, through a lens system 23, and by an amplifier 25 controls the operation of the mechanism 28 so as to maintain constant the distance between the molten material and the burner by varying the supply of powder to the flame.  In a modification, Fig. 4, not shown, the powder is stirred by a rotating vane driven by an electric motor.  In a further modification (Fig. 3, not shown) the flame is inverted and the inner tube passes downward through the porous plate.

Filed: 1955-08-08
Abstract: 772,809. Knitting. GOODRICH CO., B. F. Aug. 8, 1955, No. 22792/55. Class 74 (2). A warp knitting-machine for making carpets or like pile fabrics has two series of yarn guides adapted to traverse over the needles when the needles are lowered, one 32 of which feeds a ground yarn and the other 31 a pile yarn over stationary formers 50. After each traversing movement of these guides the needles are raised between the formers so that the ground and pile yarns extend across the backs of the needles. In this raised position the needles receive warp threads from warp guides 28. The ground and pile yarn guides are then withdrawn from between the needles and the needles lowered to knit the warp thread about the ground and pile yarns. Simultaneously the needle bed 23 is raised to cause the fabric to be gripped between its upper edge and the lower edge of the formers, Fig. 7, thereby preventing the pile loops from being stretched whilst the warp thread is knitted about the face and ground yarns. On completion of the knitting action by the needles and whilst they are in their lowered position prior to further feeding of the ground and face yarns, a bar member 66 which extends through a slot 52 in each former is advanced to engage the last formed pile loop and move it and the previous loops along the former, thereby assisting the action of the fabric take-up mechanism. A cutter 51 may be positioned on each former which severs the loops passing along the former as the fabric is taken up. Specification 763,612 is referred to.

Title: Tapping control system for melting furnaces
IPC: G05D23/27
Filed: 1953-08-21
Abstract: 739,212. Electric furnaces. BABCOCK & WILCOX CO. Aug. 21, 1953 [Aug. 28, 1952], No. 23139/53. Class 39 (3). [Also in Groups XXXV, XXXVIII and XL (b)] In a melting furnace from which material is continuously withdrawn through a tapping nozzle, the heating source is controlled photoelectrically in accordance with the temperature of the output to maintain a flow through the nozzle without freezing. As shown, a thermocouple and photo-cell 25 are arranged adjacent the path of the molten drops 15 tapped through nozzle 14. The D.C. output signal of the photocell is converted into an alternating one by means of a vibrating contact 34 amplified in a three-stage amplifier 40 and applied through a resistance capacity coupling between grid and cathode of a rectifying valve 51 forming part of a discriminator 50. The D.C. output of the discriminator is used to drive a tap rate recorder 55 and is compared with a stabilized voltage developed across potentiometer 65 in parallel with a resistor 63, the effective value of the signal potential being set by adjustment of contact 64. The difference between the reference and the measured potentials is again made alternating by a vibrating contact 71 amplified in three resistance capacity coupled stages 80, the last of which is transformer coupled to a discriminator comprising valves 91, 92. These tubes control the energization of the control coil 94 of a saturable reactor 95 forming one arm of an A.C. fed bridge circuit 98. The output of the bridge is taken across the bridge diagonal and varies in phase with the control current in the saturable reactor, This output is applied in anti-phase by means of a transformer 101 to the grids of power amplifier valves 102, 103 supplying the control winding of a second saturable reactor 20. This reactor is in series with an auxiliary electrode 16 in the furnace wall, and controls the current flow between this electrode and the nozzle through the material in the furnace, thus increasing nozzle temperature.
