Title: Improvements in or relating to metal surfacing
IPC: C23C24/00
Filed: 1936-01-17
Abstract: A corrosion-resisting layer is formed on a metal article, such as a sheet, rod, wire, or casting, by covering the article by brushing, spraying, or dipping with a mixture of a finely divided coating material, which may be a metal or a non-metal, and a vehicle which will volatilize at the temperature of treatment, and then heating the article to a temperature less than the fusion temperature of but not less than the normal annealing temperature of the coating material. The coating material is absorbed into the surface layer of the article and, if sufficient coating material is present in the mixture, this alloy layer may be covered by a layer of the coating material.  In an example, a corrosing-resisting layer is formed on iron or steel by covering it with a mixture of finely divided aluminium and a vehicle formed by heating chinawood oil, adding to the oil while cooling thickened turpentine or Venice turpentine, and, when cold, adding a thinning liquid such as turpentine or turpentine gum spirit.  A flux, e.g. a solution of boric acid in turpentine, may be added to the mixture.  The iron or steel covered with the mixture is then dried and heated to a temperature between about 750 and 1100 DEG  F., the drying and heating being preferably effected in a neutral or reducing atmosphere or in a partial vacuum.  The covering and heating may be repeated, coarse aluminium being, if desired, included in the mixture.  The coating material may be present in the form of flakes, granules, or a mixture of flakes and granules. Various materials may be used for making the vehicle, e.g. oils such as castor oil, gums, resin solutions, cellulose solutions, nitrocellulose, rubber and similar materials, metallic soaps, and emulsions such as rubber-latex mixtures.  Borax may be used as the flux instead of boric acid and the turpentine in the specific example may be replaced by linseed oil, acetone, or alcohols. Coating materials referred to are aluminium, copper, bronze, lead, zinc, tin, tantalum, cobalt, tungsten, molybdenum, beryllium, titanium, nickel, manganese, silver, uranium, vanadium, zirconium, chromium, alloys such as phosphor-copper, silicon-copper nickel-copper, nickel-silver-copper, and stainless steel, and the non-metals carbon, boron, and silicon.  The treatment of iron or iron alloys with aluminium, copper, or bronze as coating material, of copper or bronze with aluminium, and of iron with carbon is specifically referred to.

Title: Improved means for receiving radio signals
IPC: H04B1/10
Filed: 1924-01-26
Abstract: 233,024. Wright, G. M. Jan. 26, 1924. Receiving systems; atmospherics, limiting.- In a receiving system, the rounding of Morse signals and the prolongation of atmospheric impulses, due to highly-selective tuning, are compensated by passing the rectified signals through a low-pass filter to a combination of pure reactance and pure resistance, the algebraic sum of the potentials across the reactance and resistance being applied to the recorder. As shown in Fig. 1, the circuit L, C of very low damping is loosely coupled to an aerial of considerable damping, and the potentials across the condenser C are amplified by a distortionless amplifier and are rectified. The rectified current is passed through a low-pass filter LPF to a pure inductance Z connected in series or parallel with an ohmic resistance R, and the potentials arising at X, Y across the combination are applied to the recorder. The inductance Z may be replaced by a condenser or by a transformer, the potential applied to the recorder having in all cases two components, one proportional to the rectified current and the other proportional to its rate of change. The signal waves may be heterodyned before passing to the circuit LC, which is then tuned to the beat frequency. For a working speed of 30 words per minute, the filter LPF may be adjusted to cut off at about 150 cycles. The recorder may be connected in series or in parallel with the resistance R.

Abstract: 1,212,391. Casting processes. K. OTANI. 15 Jan., 1968 [19 Jan., 1967; 27 Jan., 1967; 10 Feb., 1967], No. 2225/68. Heading B3F. [Also in Division C7]  In a metal casting process, a mixture of amorphous carbon or organic carbon compound, and hydrocarbon is placed in direct contact with the molten metal at some stage during the process to produce a reducing atmosphere of carbon monoxide and hydrogen gases. The mixture may contact the molten metal in a shoot leading from a furnace to a ladle, in the ladle itself, or in the mould, by placing the mixture in the shoot, ladle or mould prior to pouring or by sprinkling the mixture on the surface of the molten metal. The hydrocarbon material is preferably a petroleum material, such as kerosene, and can be applied in a liquid, grease or wax form. The carbon or carbonaceous material may be breeze, graphite, charcoal, or organic materials such as straw, chaff, pasteboard, dry fiber, saw dust, cardboard, millboard or straw and wood ash. The hydrocarbon material may be impregnated in the carbonaceous material or the carbonaceous material may be encapsulated in metal tubes separate from the hydrocarbon material, The burning of the hydrocarbon material with the carbon or carbonaceous material produces a reducing atmosphere to prevent oxide films forming on the molten metal, provides heat to keep the molten metal fluid for a longer period, and enables the evolving gases to deoxidize the melt. The process is applied to producing pig iron, killed steel, rimmed steel, pure copper, and copper-titanium ingots, and white-metal castings. The metals produced are (a) a steel including 0À17% C, 0À35% Si, 0À98% Mn and 0À018% P; (b) a steel including 0À17% C, 0À22% Si, 0À45% Mn, 0À09% Cu, 0À022% Sn, 0À024% P and 0À019% S; (c) 0À55% C, 0À25% Si, 0À64% Mn, 0À08% Cu, 0À023% P, 0À018% S; (d) 0À16% C, 0À23% Si, 1À30% Mn, 0À022% P, 0À016% S; (e) a rimmed steel including 0À15- 0À17% C, 0À41-0À44% Mn, 0À018-0À021% P and 0À020-0À028% S; (f) a cast iron including, 3À74% C, 1À66% Si, 0À44% Mn, 0À09% P and 0À062% S; and (g) a white metal comprising 74% Pb, 14% Sb, and 12% Sn.

Title: Improvements in filling feeler mechanism for looms for weaving
IPC: D03D51/34
Filed: 1920-01-27
Abstract: 161,006. British Northrop Loom Co., Ltd., (Northrop Loom Co.). Jan. 27, 1920. Weft-feeler arrangements.-In looms having a weft-feeler motion at one side and weft-replenishing mechanism at the other side, weft-replenishment is effected after three or more picks following an indication of substantial exhaustion of weft. A spring-controlled side-swipe feeler 22, Fig. 2, has a projection 33 and a roughened end portion 34, which normally engages the weft on the bobbin and is thereby prevented from moving sideways as the feeler is pressed back. When the weft is substantially exhausted, however, the part 34 slides along the bared bobbin, so that the projection 33 moves into engagement with and operates a swing piece 31, Figs. 2, 3 and 6, which engages a finger 42 clamped to a controller-shaft 36 provided with a crank 45 engaging a leaf spring 46 on an actuator 7 pivoted to an arm 5 on the shaft 2 controlling weft-replenishment. The finger 42 has two inclined surfaces at its lower end engaging a spring-controlled adjustable locking- plunger 50, which retains the finger 42 and consequently the shaft 36 in the position to which it has been moved. The spring 46 is tensioned, the actuator being at this time prevented from rising by the end 49 of an operating-member 9, such as the weft-hammer, and consequently the actuator 7 and shaft 2 are not operated. When the member 9 returns, however, the actuator is freed and is raised by the tensioned spring 46 into the path of the member 9 and a recessed portion 58 of which subsequently engages the actuator and moves it forwards, thereby turning the arm 5 and the shaft 2, to cause weft-replenishment at the third pick after detection. During this forward movement, a cam-portion 56 engages the crank 45 and causes the shaft 36 to move to normal position, the finger 42 'being forced past the lock. The feeler 22 is returned to normal position, after side movement, by a cam &c. 57 on the feeler slide.

Abstract: 324,521. Fasting, J. S. Jan. 24, 1929. Rotary kilns.-In a rotary kiln for burning material such as cement slurry, in which transfer of heat from the gases to the material is promoted by chains hung loosely in the kiln, the points of suspension of groups of chains, or the lengths of the individual chains within a group, are so chosen that the lower parts of an ascending group of chains b take the form of a curved scoop-like, surface inclined downwards to the discharge end of the kiln. As shown, the points of suspension of the groups and of the chains within a group are successively displaced both peripherally and axially, and by this arrangement a further feeding forward of the material is effected by the drag of the chains when in their lowermost position, as at c. When the groups of chains are in the same transverse plane the lengths of the chains in a group are varied, the longest ones being nearest the discharge end of the kiln.

Abstract: 752,355. Alternators. SCHWARZ, B. April 27, 1955 [Jan. 28, 1954], No. 2629/54. Class 35. An alternator for use as an A.C. amplifier is wound with different pole-numbers, the num. ber of poles of different winding systems having an even ratio to prevent interference and each system exciting the succeeding stage through a rectifier. In its simplest form, Fig. 1, an alter. nator having four-pole output windings S and field winding E, has in addition a two, eight, or sixteen pole stator winding Sg and rotor winding R, the rotor being laminated. A control voltage applied to Sg produces a voltage in R which excites the main field winding E through rectifier Re. There may be several stages of amplification. The machine may be made selfexciting by feeding the control winding from the output through a rectifier. In this case self-regulation may be obtained by means of a similar reference control winding uniformly energized across a saturated choke. If desired an equivalent single control winding fed with a difference current may be used. The last stage output may be rectified and it is described how the system may be used to produce a constant D.C. voltage or, by means of a tachometer generator, to regulate the speed of a motor fed from the generator. It is described how, by means of suitable tappings, the same rotor winding may act simultaneously as the A.C. winding R of one pole-number, and as the D.C. winding E of a different pole number.
