  • Patent number: 5088638
    Abstract: A method for making sucker rods composed of a rod body (1) and end heads (2), consisting in upsetting the rod body end portions (8) carried out at a temperature that precludes softening of the rod body (1) metal, a thickening (9) being formed on each of the end portions (8), the width of the thickening in a direction perpendicular with the rod body (1) axis being equal to or in excess of the head (2) maximum diameter in the weld joint place, while its length exceeds the width of the heat-affected area (17) involved in the welding process. A transition portion (10) shaped as a solid of revolution has a cross-section which smoothly and continuously decreases from the thickening (9) towards the rod body (1). The upsetting procedure is followed by friction welding of each of the end heads (2) together with the thickening (9) on the rod body and portion (8) and by turning the weld joint zone.

  • Patent number: 5004037
    Abstract: The tube is at least two inches long and has successive sections of progressively smaller diameters to produce a correspondingly shaped sprue passage communicating with a pattern cavity in a casting investment, so that fluid casting material passes with increasingly fluid velocity between an inlet and outlet of the sprue passage during the casting process. A bulbous portion of the tube is spaced from its free end, to form a reservoir chamber in the sprue passage, spaced sufficiently from the pattern cavity, so that casting material flowing through the sprue passage attains maximum velocity at the outlet of the passage entering the pattern cavity.

  • Patent number: 4986333
    Abstract: The ceramic core is located within the ceramic mold by the insertion of recrystallized alumina pins through the wax encasing the core prior to encasing the whole in a ceramic slurry; on the subsequent removal of the wax, the molten metal, i.e. superalloy, is injected into the resulting space; the recrystallized alumina pins remain intact during the casting process hence substantially increasing the success rate of achieving accurate core locating during casting solidification.

  • Patent number: 4967444
    Abstract: A double-winged door spring is biased for closing with a mechanism for damping of the closure movement and includes a closure sequence control, particularly of a fire-resistant door, in which the damping of the movable door portion is accomplished through a hydraulic damping element with throttled overflow. The hydraulic damping element includes two oppositely controlled pressure chambers defined by a double-acting piston and a valve disposed in the overflow conduit connecting the two pressure chambers, the valve being actuated directly or indirectly through the stationary door portion. By the valve being disposed in the overflow conduit, actuation of the movable door portion can be inhibited until the stationary door portion is closed.

  • Patent number: 4951349
    Abstract: A motion regulator for a hinge such as, for example, a tripartite eyeglass hinge, with at least two hinge tabs and a hinge screw, a sleeve surrounding the hinge screw disposed in a hinge eye of the hinge tab. The sleeve projects beyond the hinge tab and rests against a neighboring hinge tab or tabs. In order to obtain an objective that a braking torque, determining the motion characteristics of the hinge, is substantially constant and independent of the tightening torque of the hinge screw, a spring-elastic element is arranged at least between the hinge tab wherein the sleeve is located and the hinge tab movable with respect to this hinge tab. The spring-elastic element, resilient in the axial direction with respect to the hinge screw axis, is in contact under a pretensioning with a contact surface of at least one hinge tab, which surface is rotationally symmetrical with respect to the hinge screw axis.

  • Patent number: 4949777
    Abstract: A continuous casting process introduces the factor of rate temperature change for detecting break out in the cast metal. Introduction of rate of temperature change as a parameter representative of the cast metal condition is successful for avoiding the influence of variation of the casting condition, fluctuation of the powder to be introduced between the casting mold wall and the cast metal, casting speed and so forth. For achieving accurate detection of break out of the cast metal by introducing the temperature change factor, casting mold wall temperatures are measured at various measuring points which are circumferentially aligned. Rates of temperature change at each measuring point and average rate of temperature change of all measuring points are derived and compared for making judgement of possible break out when the difference of the rate of temperature change at each measuring point and the average rate of temperature change becomes greater than a predetermined value.

  • Patent number: 4948031
    Abstract: A process for joining first and second aluminum sheets in which the bonding surfaces of the aluminum sheets have their aluminum oxide layer replaced by a zinc layer and the zinc layers are plated with a non-alloy metal bonding material such as cadmium. The first and second aluminum sheets are then assembled and fastened together with an engaging means for holding the sheets together, and then the assembled sheets are placed in a vacuum. The sheets are subsequently heated in the vacuum thereby creating a bond of cadmium between them, removed from the vacuum, and then passivated.
