Title: A process for producing titanium steel
IPC: C21C7/00
Filed: 1935-04-02
Abstract: In the production of titanium steel, an iron bath is covered with a slag which is as free as possible from silicic acid and contains titanic acid and lime in the proportions of 70 to 30, and from this slag, by reduction with carbon, titanium is introduced into the iron bath in a quantity which is sufficient to remove the nitrogen, sulphur, and oxygen contained in the bath into the slag in the form of titanium compounds and then to convert all the carbon of the iron bath into titanium carbide corresponding to the formula TiC, the amount of titanium in the steel not exceeding 3 per cent.  If a phosphorus-containing iron bath is used, the process is carried out to yield a steel containing 0,05-0,5 per cent of phosphorus and a titanium carbide content of 0,5-1,0 per cent, such a steel being suitable for structural purposes.  If the steel is required to be corrosion-resistant, the proportion of phosphorus exceeds 0,5 per cent but does not exceed 1 per cent.  Titanium steels for deep drawing sheet are produced by adding to the steel containing not more than 0,5 per cent of titanium carbide, 0,3 per cent of silicon and 0,1 per cent of aluminium, and for transformer stampings 4 per cent of silicon and 0,1-0,5 per cent of aluminium.

Abstract: 423,075. Bearings; lubricating. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Robins Conveying Belt Co. ; Meade Avenue, Passaic, New Jersey, U.S.A.) April 4, 1934, No. 10230. [Classes 12 (i) and 12 (iii)] [See also Group XXVI] A bearing has a sealing device comprising a flexible annular ring 29 secured to the bearing casing 130 in spaced relation to flanged members 26, 27, carried by the rotatable shaft 90. The latter, which may support an idler conveyer roller 7, is hollow. The casings 130 have end nipples 16. A lubricant gun is applied to one of the nipples 16 to charge the adjacent bearing. The pressure of the lubricant flexes the inner edge of the ring 29 into sealing engagement with the flange 27. Continued operation of the gun charges the bearing at the other end of the roller, and when the operation is completed this is indicated by the escape of lubricant from the second nipple 16. Upon release of the charging means the lubricant pressure throughout the system is equilized and the rings 29 resume their normal position in spaced relation to the flanges 26, 27. In a modification embodying a stationary hollow shaft 9, Fig. 3, the sealing device is a cork ring 29 slidable upon a sleeve 24. During the charging operation the ring 29 is pressed by the lubricant against the flange 27, and when the charging operation is completed it takes up a position spaced apart from the flanges 26, 27. The bearings of a series of conveyer rollers may be charged in succession, the hollow shafts of the rollers being in mutual communication and the bearing finally charged having a relief discharge port such as 16.

Abstract: 879,880. Winding machine stop mechanisms. MACKIE & SONS Ltd., JAMES. March 24, 1959 [Dec. 24, 1957], No. 10253/59. Divided out of 872,608. Class 120(2) In a yarn winding machine of the surface driven type and having an automatic stopmotion which comes into operation to interrupt the drive of the package being wound when the yarn breaks or runs out, means are provided to cause breakage of the yarn as a consequence of the roll reaching a predetermined diameter and thus cause the stop motion to operate. In the machine shown 10 is a driving shaft having fixed to it rollers 12 on which rest roll packages 14 being formed. The machine is fitted with a stop motion (not shown) which operates when the yarn being wound breaks or runs out. Pivotally mounted on the frame of the machine at 28 there is a feeler 30 which lightly touches the surface of the roll. Also pivoted at 28 there is an arm 32 having a notch 34 at its outer end which notch engages over a pin 36 on bracket 37 fixed to plate 38 pivoted to the machine frame at 40. The parts 30 and 32 are connected by a pin and slot connection 42. Normally the parts are as shown in full lines with the feeler 30 out of contact with the roll and the plate 38 held by pin 36 and notch 34. When the roll reaches its full size it moves the feeler 30 such that notch 34 disengages pin 36 and the plate 38 falls on to the head of the bobbin 16, as shown in broken lines, and causes breakage of the balooning yarn. This breakage then operates the stop motion to stop the machine. In a second embodiment the plate 38 carries a thread guide at its end which guide takes the place of guide 20 shown and in a further embodiment yarn nipping means are provided for breaking the yarn.

Abstract: 183,900. Schmidt, F., Girard, E. L., and Messlein, M. A. April 12, 1921. Working-fluid supply.-A jet-wheel turbine is actuated by products of combustion from exploding devices, Fig. 10, supplied with compressed mixture from a multi-cylindered compressor, Fig 3, the devices having pressure-operated inlet and outlet valves. Steam may be induced into the exploded gases before they reach the rotor. The compressor comprises four pairs of cylinders 24 - - 27, the piston-rods 47, 48 of which are actuated through levers 57, a link 55 and a crank 52 from a power-shaft, so that adjacent pairs, such as 24, 27, simultaneously compress charges, drawn in from a carburettor through valves 28, 29. The charges are delivered through valves 33, 34 into pipes 31, 1.01 to one of four exploding-devices 75 round the turbine casing. The mixture enters the device, Fig. 10, through a spring-pressed valve 99 and is exploded by a plug 94 which is timed from the compressor. The pressure of the exploded gases acts through ducts 93 to shift a hollow piston 90 against a spring 91, so that the gases can escape into the nozzle 80. The velocity of the gases produces a vacuum effect within thepiston 90, drawing water through holes 106 in a tube 105, which is controlled by a tap 104. Thewater is vaporized by the heat of the piston and mixes with the products of the next explosion when they leave the device. The mixed gasesimpinge tangentially on the rotor buckets.
