Title: A method for Casting a Spheroidal Graphite Iron Pipe
IPC: B22D13/10
Filed: 1967-03-02
Abstract: 1,157,054. Casting processes. UNITED STATES PIPE & FOUNDRY CO. 2 March, 1967 [3 March, 1966], No. 10036/67. Heading B3F. [Also in Divisions C3 and C7] In producing castings, particularly pipes in centrifugal casting machines, from ductile spheroidal graphite material, inoculant material such as calcium-silicon or ferro-silicon is added to the poured molten iron just before solidification and the solidification and cooling rates of the cast pipe are controlled to produce a grain structure mainly of ferrite, with a minimum of pearlite and carbide. As applied to casting pipes by the Lavaud method the inoculant may be added to the molten metal in the pouring ladle, in the pouring trough, blown in powdered form into the flow of metal from the trough to the mould, and added as a coating to the mould surface. The inoculant coating may be added on top of a refractory layer of diatomaceous silica and bentonite applied to the mould in a wet slurry. The solidification of the pipe at a controlled rate is achieved by water sprays applied in timed periods so that graphitization is substantially completed and sudden freezing does not produce the formation of carbides and too slow freezing does not allow the nucleating effect of the inoculating material to be dissipated. The cooling of the solidified pipe through the transformation range of the iron is also controlled to allow the pearlite to be eliminated and a ferrite structure produced. The cooling of the pipe may be slowed down by blowing a dry insulating blanket of material inside the pipe after solidification. The finished pipe may be annealed to further improve the ferrite structure of the material.

Title: Improvement in means for operating suction actuated devices in connection with the suction passage of an internal combustion engine
IPC: B60T13/48
Filed: 1926-04-16
Abstract: 252,687. Bragg, C. S., and Kliesrath, V. W. May 28, 1925, [Convention date]. Spray carburettors.-In engines the suction of which is utilized to operate a suction-actuated device, " stalling " of the engine and delay in re-starting due to weakening of the combustible mixture by air exhausted from the device, are prevented by introducing fuel into the air withdrawn from the device when the amount of air so withdrawn is in excess of that which the combustible mixture can assimilate without producing " stalling " of the engine. The main carburettor is shown at 66, Fig. 1. The auxiliary carburettor, Figs. 3, 4, and 7, for supplying fuel to the air withdrawn from the suction device comprises a body formed in two sections 76, 76<a>, clamping between them a flexible disc 77 with slits 77b, terminating in a central aperture 77<a>. A nipple 78, in communication at 79 with a fuel supply, forms a seat for a needle valve 80 having screwed thereon a spider 80<b> against which a spring 80<a> presses. Surrounding the needle valve is a sleeve 81, Fig. 4, terminating in a disc 82 and provided with a cone 81<a>, which is pressed by a spring against the coned ends of two adjustable screws 83. Normally the air drawn in through 76<c> merely passes through the slits 77<c> and between the disc 82 and the aperture 77a, but should the amount of air become excessive the sectors 77<c> are deflected downwardly and, engaging the spider 80<b>, open the needle valve to admit fuel. Adjustment is effected by moving the disc 82 by the screws 83. In a modified form, the disc 77 is cut away so as to leave narrow flexible strips at its periphery, the aperture 77<a> is dispensed with and adjustment is effected bv a valve-controlled by-pass in a partition between the inlet and outlet passages of the carburettor. Specification 245,444, [Class 8 (ii), Air and gases, Treating &c.], is referred to.

Filed: 1948-04-15
Abstract: 638,251. Winch control. CHRISTIAN, G. R., and BRITISH ENGINES, Ltd. April 15, 1948, No. 10474. [Class 78 (v)] Refers to the type of winch set out in Specification 606,604 in which the clutching and braking means are controlled by arms 10 and 3, the brake arm 3 having an adjustable weight 5 from which projects a lateral lug on which the clutch arm rests, and retaining means R on the clutch arm whereby when the brake arm and clutch arm are raised to the hoisting position the clutch arm is held and there are provided means M on the brake arm whereby on the brake arm moving a predetermined distance away from the hoisting position the retaining means are retracted and the clutch arm caused to move toward the clutch disengaged position. The inventive step lies in the provision of a control rope 1 so connected to the brake arm 3 and to clutch arm 10 that, when the rope is pulled, the clutch arm is first moved until the clutch begins to engage and then the brake arm is removed to disengage. As shown, control rope 1 passes round pulley 2 on brake arm 3 and through bifurcated lug 4, and carries a fixed block 11, and is secured to bellcrank lever 6 journalled on brake arm 3. When the rope is pulled the bellcrank lever, is rotated and its second arm 7 raises the clutch arm 10 till the clutch is partly engaged after which position the block 11 engages with lug 4 on the brake arm, and the brake arm then moves upward with the clutch arm so that as the clutch moves into clutching position the brake moves into unbraking position. The object is to enable a load when suspended stationary in mid air to be further raised without a sudden drop. Alternatively, the control rope may pass through an eye on the clutch arm and an eye on the brake arm and be secured at its end to the brake arm. Small blocks are fixed on the rope to engage the eyes so that the clutch arm is raised before the brake arm.
