Abstract: 206,899. Igranic Electric Co., Ltd., Curtis, A. H., Wright, S. R., and Mackley, A. H. Aug. 8, 1922. Inductances. - In a multiple-coil variable inductance for wireless signalling having independently supported angularly adjustable single coils, the coils are angularly adjustable about a diametral axis parallel to the axis or axes of the primary angular adjustment of the coil supports relatively to each other, the relative position of the coil supports and the angular position of the coils in the supports being adjusted separately or simultaneously for coarse and fine tuning. The electric connections for each coil may pass through the diametrically opposite pivots to diminish leakage. In one form with three coils 25, Fig. 1, the ends of the coils are connected to pivots 24 detachably engaging holes or recesses in resilient horizontal arms 20, 21. The coils are angularly adjusted about the pivots 24 by means of an operating rod which is forked at one end to engage the square insulating spindle 68, or which is rotatably mounted in one of the arms 20, 21 and connected to the spindle 68 by worm and wheel gearing, by a flexible drive in the form of a spiral spring connecting the end of the rod to an end of the spindle, or by a friction drive comprising a pulley 72, Fig. 6, on the operating rod 46 engaging a friction disc 74 on the coil. 'Each coil may be mounted on its pivots by means of plates 64, Fig. 1, on the coil engaged by bent-over strips 65 and provided with sockets to engage the spindle 68, or flat coils may be fixed in recesses in a tubular spindle into the ends of which the pivots 24 are screwed. The arms 20, 21 have bent ends 30 engaging grooves 29 in insulating carrier rods 26, the arms being adjustably locked in the grooves by screws 31, 36 engaging distance pieces 32. Different diameters of coils may thus be received between the arms 20, 21, and the positions of the coils may be adjusted along the rods 26. The centre rod 26 may be fixed and the outer rods rotatably mounted and operated by means of levers 40 clamped to the rods 26 or to the arms 20, 21 or by means of the rods provided for rotating the coils about the pivots 24. The electric connections for each coil engage holes 39 in the pieces 32 or are clamped in holes 37 in the screws 36 by spring plates 38, the current passing through the arms 20, 21 and pivots 24. Coils of different diameters may be used together to provide variometer adjustment of one coil within a larger annular coil. In a modification, Fig. 2, the arms 20, 21 are adjustably locked on guides 50, 51 secured at opposite sides of an insulating block 54 carrying plug-andsocket couplings to engage corresponding couplings on standard coil holders having angularly adjustable coil supports. The Provisional Specification describes pivotal supports for a coil in the form of inner and outer tubes in frictional engagement, the inner tube being rotated for fine adjustment of the coil by means such as worm and wheel gearing.

Abstract: 1,156,823. Degassing molten metal. UNITED STATES STEEL CORP. May 18, 1966 [June 2, 1965], No.22142/66. Heading C7D. In a method and apparatus for degassing a continuous stream of molten metal the latter passes through successive stages of increased vacuum, being conducted through a first tube terminating within a second tube leading from one stage to the subsequent one so that there is defined for the metal a flow path of increasing cross-sectional area, the metal stream leaving the first-mentioned tube expanding to form a barrier between the two stages and thereby maintaining the vacuum differential between them. As particularly described and illustrated, Fig. 1, degassing vessel 10 is fed alternately by ladles 14a, 14b through inlet sections 11a, 11b, respectively, and discharges through openings 15a, 15b into a suitable container such as a continuous casting mould. Each inlet section may be closed by a valve 34 while the ladle is changed. Metal discharged from the ladle 14a passes through tube 40, on leaving which it is dispersed by the action of vacuum produced through lines 17a and 18 to fill the cross-section of tube 32, the stream" further expanding as it passes downwards to fill sleeve 33 and provide a vaccum barrier between the final and preceding stages. The metal then coalesces in the well of vessel 10, from where it is tapped after a barometric height has accumulated, discharge being controlled by the spring-loaded plate valve shown in Fig. 5.

Filed: 1946-07-26
Abstract: Oil-modified alkyd resins are prepared by heating a mixture of castor oil, a polyhydric alcohol and a polybasic acid or anhydride thereof at a temperature between 260 DEG  and 270 DEG  C. until the initial decrease in viscosity of the reaction mixture has substantially ceased, and, before there is any substantial increase in viscosity adding a sufficient quantity of polyhydric alcohol and/or polybasic acid or anhydride thereof at such a temperature as to reduce the temperature of the reaction mixture to a value not exceeding 230 DEG C., and continuing to react the added polyhydric alcohol and added polybasic acid or anhydride thereof at a temperature between 160 DEG and 230 DEG  C. and adding any further polyhydric alcohol and/or polybasic acid or anhydride which may be necessary to produce a reaction product, the oil content of which does not exceed 50 per cent thereof and which contains a small amount of free polyhydric alcohol.  Cooling means may be provided to remove the excess heat of the reaction vessel. Preferably, the initial reaction mixture contains 5-75 per cent excess of glycerol over the equivalent amount and contains 40-95 per cent of oil.  Any further additions of polyhydric alcohol are preferably made before the addition of further polybasic-acid. Suitable alcohols are glycerol, pentaery, thritol, ethylene glycol, trimethylol propane mannitol, sorbitol and butyne-diol, and suitable acids are phthalic acid and anhydride, tetrahydrophthalic acid, tetrachlorophthalic anhydride, methylene di-salicylic acid, maleic, fumaric and citric acids, and maleic and fumaric acid adducts with terpenes and cyclo-olefines. In examples, castor oil, glycerol and phthalic anhydride are heated at 260-270 DEG C., and when the minimum viscosity is passed sufficient glycerol is added to reduce the temperature to 230 DEG  C. Further phthalic anhydride is added, followed by further heating, firstly at 230 DEG C. and then at 180 DEG  C.; (2) the procedure of (1) is followed, but a further addition of phthalic anhydride and glycerol is made whilst heating at 180 DEG  C.; (3) castor oil, phthalic anhydride and glycerol are heated at 260-270 DEG  C. and pentaerythritol added when the minimum viscosity is passed to reduce the temperature to 230 DEG C.  Phthalic acid is added and heating continued at 220 DEG  C.; (4) sorbitol replaces the pentaerythritol of (3).  The products dissolved in xylene are p  suitable as varnishes, and cobalt linoleate or naphthenate driers may be added.  Specifications 431,495 and 474,620 are referred to.  A sample has been furnished under Sect. 2 (5) of a product obtained by heating castor oil glycerol and phthalic anhydride, and when the minimum viscosity is reached adding more glycerol and phthalic anhydride and heating at 220 DEG  C., then adding butyne diol and heating at 210 DEG  C.  The product at 200 DEG C. is dissolved in xylene.
