Patent ES-476092-A1 (ES)
Title: Pressure vessel
IPC: F15B1/08
Filed: 1978-12-18
Abstract: A pressure vessel comprising a casing or container formed from two substantially cup-shaped shells, each of said shells having their free edges or rims located in juxtaposition by means of an internal annular retainer member which properly spaces such free edges to permit connection thereof by an annular weld and which also serves as the support for a deformable partition positioned in the container. The retainer member formed from a metal having a melting point below that of the shells has a first thickened annular portion of relatively great mass on one side of said annular weld and a second annular portion of smaller mass on the other side of said annular weld, said annular portions having outer surfaces in intimate contact with the inner surface of the casing and define two annular contact zones separated by an intervening zone in which the weld is formed, said deformable partition being supported by said retainer member at the edge of said first annular portion remote from the annular weld. Two cup-shaped shells have their edges or rims in juxtaposition to be retained together by welding, it is important that the welding metal engage the entire thickness of the juxtaposed rims in order to provide a dependable bond.

Title: Accumulator conveyor.
IPC: B65G13/06
Filed: 1979-08-30
Abstract: An accumulator is disclosed in which the articles are transported on a bed of carrier rollers. Beneath the rollers a plurality of devices, arranged in tandem lengthwise of the conveyor, provide vertical support for the propelling member. Each support has a bracket pivotally mounted between its ends with a propelling member support pulley at one end and a bracket manipulating propelling member tracking roller at the other end. The tracking roller is tapered and is mounted for rotation about a shaft extending transversely of the propelling member. The shaft is longer than the roller permitting the tracking roller a limited amount of axial travel. By changing the angular relationship between the roller and propelling member, the point of contact between the propelling member and tracking roller is shifted lengthwise of the roller, resulting in pivotal movement of the bracket which raises and lowers the propelling member to effect drive and release of the carrier rollers forming the conveyor bed. Article actuated sensors control the angular position of the tracking roller.

Title: Method and apparatus for laying a pipeline on the sea-bottom.
IPC: F16L1/20
Filed: 1980-06-30
Abstract: Apparatus and method for laying a pipeline on the bottom of an ocean wherein a wheel-like, buoyant body is adapted to carry a single, continuous length of pipe in the form of horizontal convolutions from a first site at which the pipe is wrapped on the body to a second site where the convolutions are moved into vertical positions and the pipe is unwrapped from the body and allowed to gravitate toward and to be laid on the bottom of the ocean. The pipe is wrapped on the body when the latter is horizontally disposed and floating on the water near a dock, and the wrapping can be accomplished whether the elastic bending limit of the pipe is exceeded or not. The body with the convolutions of pipe are towed to the second site while the body and the pipe remains horizontally disposed. Then a tank forming part of the body receives sea water to unbalance the body and cause it to be moved into a vertical position. In this position, the body is simultaneously towed forwardly and rotated about a horizontal axis below the upper level of the water to allow the pipe to be vertically unwrapped from the body and to gravitate therefrom. The body normally has a curvature less than the curvature at which the pipe exceeds its elastic bending limit however the body could have a greater curvature for some specific uses. A second, smaller tank having a power actuated mechanism therein is coupled by gear means to the body near its outer periphery to rotate the latter upon actuation of the mechanism during a pipe laying operation. The mechanism can also be used to rotate the tank when the body is in a horizontal position near a dock to allow the pipe to be continuously wrapped onto the body after being formed from pipe segments connected together in end-to-end relationship.

Title: Liquid fuel injection pump apparatus
IPC: F02M41/14
Filed: 1981-02-19
Abstract: The appts. includes a body in which is journalled a rotary distributor member having a transverse bore which accommodates a pumping plunger movable inwardly by cam lobes on a surrounding cam ring. Fuel displaced by the plunger during inward movement by the cam can flow to an outlet by way of a passage and an outlet port providing a passage extending to the periphery of the distributor member is covered by a muff. The interior surface of the muff has wedge shaped portions which obturate the port or ports at the end of the passage. This causes the fuel to be delivered to the outlet and the angular and axial settings of the muff can be varied by actuators.

Title: Tilting vessel for the treatment of cast iron melts.
IPC: C21C1/10
Filed: 1983-01-20
Abstract: A method of and a ladle for the treatment of a cast iron melt with a substance capable of inducing the formation of spheroidal graphite utilizes an elongated generally cylindrical vessel lined with a refractory and formed at opposite ends with cylinder bottoms. The vessel can be tilted between a horizontal and upright orientation and angularly displaced about a longitudinal axis at least in its horizontal orientation. A partition in the vessel adjacent one of the cylinder bottoms defines a chamber at one end of the vessel opening within the vessel toward the opposite end thereof and disposed at an upper portion of the vessel in its horizontal orientation. A closable opening at the other end of the vessel enables a cast iron charge to be introduced into the vessel in the horizontal orientation thereof. The vessel is then tilted upwardly to effect the reaction and swung back to its horizontal orientation for deslagging before the charge is tapped by angular displacement about the longitudinal axis.
