US11549626B2	Method of forming a cooling plate In an embodiment, a method of forming a cooling plate, comprises laser welding a plurality of weld lines to physically connect a first substrate and a second substrate wherein the plurality of weld lines forms an inflatable track; and inflating the inflatable track with an inflation fluid to form a cooling channel in the cooling plate. In another embodiment, the cooling plate can comprise a first substrate and a second substrate and a plurality of weld lines can form a fluid tight seal for a cooling channel located therebetween.
US11549623B2	Ball joint seal The pipe ball joint includes a casing having a socket portion with a substantially spherical interior surface and a first pipe segment extending from the socket portion. The socket portion has an annular groove disposed adjacent the partially spherical interior surface. A ball pipe section includes a ball segment received in the socket portion of the casing and a second pipe segment extending from the ball segment. A seal assembly is received in the annular groove of the casing and is disposed against the ball segment of the ball pipe section. The seal assembly includes a plurality of nested seal rings that each include a concave face and a convex face.
US11549620B2	Screw joint for oil well pipe A screw joint in which an efficient screw length of a joint portion is achieved. This screw joint is for an oil well pipe of an integral type and includes: (i) a pin that is provided with a male screw portion which is a male taper screw, at one end of a steel pipe; and (ii) a box that is provided with a female screw portion which is a female taper screw fitted to the male screw portion, at one end of the steel pipe, in which a structure, in which the pin and the box are in metal contact with each other to seal a fluid, is provided at least at one place of a seal portion on an outer peripheral surface side of a pipe end side of the pin and a seal portion on an inner peripheral surface side of a pipe end side of the box.
US11549615B2	Stinger for a pipe laying operation A stinger including a first member formed from a first non-metallic material, a second body member formed from a second non-metallic material, and a plurality of cross-support members disposed between the first body member and the second body member. The first body member includes a first lower portion, a first upper portion, and a first intermediate portion disposed between the first lower portion and the first upper portion. A width of the first lower portion is greater than a width of the first intermediate portion and a width of the first upper portion, and wherein the width of the first upper portion is greater than the width of the first intermediate portion. The second body member includes a second lower portion, a second upper portion, and a second intermediate portion disposed between the second lower portion and the second upper portion.
US11549613B2	Valve plate with free micro-balls The valve plate (1) with free micro-balls allows a fluid (2) to flow from an upstream volume (3) to a downstream volume (4) and not in the reverse direction, and comprises a circulation plate (5) crossed through by a circulation orifice (6) terminated by a micro-ball seat (7), a permeable guide plate (9) parallel to said plate (5) being crossed through by a guide cylindrical orifice (10) which houses a micro-ball (8) which rests on said seat (7) so as to close said orifice (6) or rests on a permeable micro-ball stop abutment (11), a spacer (12) being interposed between said plate (9) and said plate (5), a discharge passageway (13) crossing through said plate (9) to allow the fluid (2) to flow when the micro-ball (8) does not rest on said seat (7).
US11549611B2	Fault prediction in valve systems through Bayesian framework Systems and methods for fault prediction through a Bayesian framework are provided. Fault prediction for a valve system may be provided by generating a Bayesian framework by collecting a plurality of historical parameters related to opening and closing of a valve across a plurality of operational legs; generating a plurality of historical feature metrics based on the plurality of historical parameters; in response to detecting a fault, defining a prefault state corresponding to the historical feature metrics; monitoring a plurality of operational parameters related to opening and closing of the valve during a given operational phase of an operational leg; generating a plurality of operational feature metrics based on the plurality of operational parameters monitored during the given operational phase; and in response to determining, using the generated Bayesian framework, that the operational feature metrics indicate the prefault state of the subsystem, generating a notification.
