F16J 912

US Classification:

277459, 277497, 277499

Abstract:

An engine piston compression ring designed to reduce the negative effects of ring end butting and reduce blowby. The compression ring has a gap forming an angle with a longitudinal axis of the ring or with a radius drawn from the axis. A relieved portion is provided along the upper or inner side of the ring adjacent one end, depending upon the direction of the gap angle. The relieved portion slopes along the upper or inner side toward the one end where the longitudinal thickness of the ring is smallest.

International Classification:

B23K 20/12
B23K 31/02

US Classification:

2281121, 228 21

Abstract:

A surface of an article is heated and subjected to pressure by operation of a friction stir tool. The pressure of the face of the tool on the article surface, and the speed of rotation of the tool and of its progression along the surface of the article, are controlled to progressively hot-work a specified surface area. The face of the tool may be round and have a profiled, axially extending, smaller diameter pin for higher concentration of frictional heat and load and for plasticizing a surface layer of the workpiece. Such hot work may be applied for reducing surface porosity or for producing another change in the surface microstructure, or for effecting another change in surface material properties.

US Classification:

123196R, 123196 S

Abstract:

A method is disclosed for initiating oil injection into a cylinder of an internal combustion engine prior to engine start-up, the oil injection protecting the engine from damage caused by insufficient lubrication during the start-up. The method includes processing data to modulate a lubrication initiation modifier and initiating the oil injection on the basis of the lubrication initiation modifier.

US Classification:

370324, 370315, 370319, 370503, 375215, 375294

Abstract:

A method and apparatus for performing time synchronization is provided. The method/apparatus includes, at a radio subsystem: receiving, from a digital subsystem, a first signal via the link, where the link not dedicated to timing synchronization; determining a time difference between the first signal and a second signal; converting the time difference to a time error, sending, via the link, the time error or time difference to the digital subsystem. The method further includes, at the digital subsystem, inputting the time error, received from the radio subsystem, to a phased locked loop (PLL) in order to adjust an oscillator frequency so as to reduce the amount of the time error and thus synchronizing the radio access network with the second signal received at the radio subsystem, without the need for an additional connection between the digital and radio subsystems.

Abstract:

A mold for forming a plurality of rotors includes a plurality of lamination stacks, wherein each lamination stack defines at least one void therethrough; a tube having a central longitudinal axis, wherein each lamination stack is concentrically spaced apart from the tube to define a channel therebetween; a plurality of washers each having a shape defined by a first diameter and a second diameter that is greater than the first diameter, wherein each washer is configured to concentrically abut the tube and define a feed conduit interconnecting with the channel; and a shell disposed in contact with each lamination stack and concentrically spaced apart from each washer to define a plurality of ducts, wherein each duct is interconnected with the at least one void of at least one lamination stack. A mold system and a method of forming a plurality of rotors are also described.

US Classification:

123195 R, 164 98, 420591

Abstract:

A major engine casting, such as an engine block or a cylinder head, fabricated of either magnesium or aluminum alloy, has a cast-in-place metal tube or form embedded within it. The tube or form enables circulation of liquid while substantially physically isolating the casting alloy from the circulating liquid and thereby restricting or eliminating corrosive interaction between them.

International Classification:

B32B 15/01

US Classification:

428594, 2281101, 228111

Abstract:

Selected surface regions of coulomb vibration damping strips are bonded face-to-face by ultrasonic welding to a surface region of an article that may experience excessive vibration in use. In one embodiment, prior to welding, the intended facing side of the damping strip is treated to form surface regions that are oxidized, roughened, or coating so that the treated regions do not weld to the article surface. In another embodiment of the invention the ultrasonic welding process is controlled so as to produce regions (sometimes randomly interposed regions) of welded and non-welded regions between the damping strip and adjacent article surface. The unbonded regions of the otherwise welded strip lie in closely-spaced, interfacial, frictional contact with the adjacent article surface to damp vibration in the article. Other processes may be used for welding a damping strip to a surface of an article while leaving un-bonded, friction damping regions between regions of the damping strip and the facing surface of the article.
