Abstract: A method is described for continuously casting an ingot of a metal alloy of the type having a substantial liquidus-solidus temperature range so that the ingot will have a "smooth" surface free of hot-tears. A succession of substantially equal volume quantities of the molten alloy is poured into a continuous casting mold at a pressure of less than about 10.sup.-3 Torr. The quantity of each pour is sufficient to cover the entire cross section of the mold by flow under the influence of gravity and each quantity is allowed to substantially solidify between pours to form successive axial increments which make up the ingot. Each increment is allowed to cool for at least about 30 seconds between pours to form a sufficiently solid side-wall to prevent hot-tears.

Abstract: A subsea well assembly has a casing hanger that lands inside the wellhead with a locking device to lock the hanger in the wellhead. The locking device includes a collar mounted to the hanger body and movable relative to the body between a lower storage position and an upper set position. The collar contacts a landing shoulder located in the wellhead to move to the set position. Washers located between the collar and the hanger body allow the hanger body to move downward when the collar contacts the landing shoulder. The washers deflect downwardly due to interference fit when the hanger moves to the set position to resist upward movement. As the hanger body moves downward, a split ring is pushed outwardly by inclined surfaces to engage locking grooves formed in the interior of the wellhead for supporting the casing hanger.

Abstract: An enhanced oil recovery technique includes the predetermination of a desired steam distribution within a steam flood pattern, which preferably is proportional to the volumes of oil in place within various sectors of an area of a subsurface formation. These sectors are associated with the various producing wells of the steam flood pattern. Initial steam distribution is then determined. Subsequently, one or more of the producing wells has its production rate modified so that the final steam distribution within the formation will more closely approximate the predetermined preferred steam distribution.

Abstract: In the apparatus and method of the invention, acoustic energy is propagated in two slightly differing, or offset, circumferential paths in such a way as to interact with the formation under investigation. The propagating energy is detected and the resulting waveforms are compared using semblance. The waveforms corresponding to the respective paths will be quite similar provided that the length of the paths are equal and that there are no fractures or other similar anomalies between the source and receiver. The waveforms for the respective paths will be quite dissimilar, however, if a fracture or similar anomaly does lie between the source and receiver for the respective paths.

Abstract: A disc brake assembly for the front or rear wheel of a motorcycle including a brake disc having pairs of projections located on its periphery at 120.degree. intervals. The pairs of projections may be placed on either the outer periphery or the inner periphery of the brake disc. The projections define open ended recesses receiving bosses formed integrally with the wheel hub, and partially surrounded by hardened retainers and structural members. A bolt threaded into each boss prevents disassembly of the bosses and recesses but is not subjected to forces caused by thermal expansion of the brake disc during braking.

The disabling device (107, 245) may be selectively actuated to prevent the brake control device (20, 220) from operating during certain predetermined circumstances.

Abstract: In a synchronizing mechanism for clutches, there are provided between the gear shift sleeve and the synchronizing ring (14,15) stop bodies in the form of dogs (25, 26) which are in contact with the gear shift sleeve (between the teeth 34) in the circumferential direction by form-locking engagement and in the axial direction through spring-loaded stop balls (21) and in the neutral position are spaced from the synchronizing ring by a distance substantially equal to the axial extension of the check faces (32, 33) between the gear shift sleeve and the synchronizing ring. In this manner it is ensured that during shifting the axial force previously exerted through the check faces (32, 33) on the synchronizing ring (for instance 15) is replaced by an axial force which is transmitted by the dog and which prevents the synchronizing ring from coming off the countercone before the form-locking connection between the gear shift sleeve and the clutch body is established.

Abstract: There is disclosed a clutch which will release under overload and will reset automatically upon speed reduction of the driving element. Two radial bars are fixed to the driven shaft; a driving wheel is rotatably mounted on the driven shaft adjacent the bars, and pivotally carries a pair of diametrically-opposite elongated pawls biased by tension springs to a radially-inwardly-extending position within the driving wheel to engage the respective arms, whereby the driving wheel drives the driven shaft. Under overload, the arms cause outward pivotal movement of the pawls against the bias of the springs, whereby the arms are cleared by the pawls, which remain in outwardly-pivoted position under centrifugal force until speed reduction of the driving wheel.

Abstract: The friction clutch for a motor vehicle comprises a fly-wheel having a clutch cover on which a diaphragm spring is supported through retaining bolts. The retaining bolts axially displaceably pass through the diaphragm spring and the clutch cover and are secured on the side axially remote from the diaphragm spring on a plate spring which is supported on the clutch cover. The plate spring carries all retaining bolts and concentrically surrounds the rotation axis of the clutch. The plate spring ensures play-free clamping in of the diaphragm spring. The plate spring is preferably independently centered on the clutch cover so that the passage openings of the retaining bolts can be of such large dimensions that no friction occurs.

Abstract: An overtravel stop for a rotating shaft has a pair of gears associated with the shaft to rotate therewith. Each gear engages an associated limiting gear and the two engaged gear pairs have different gear ratios. One of the limiting gears is threaded over a shaft which is secured for rotation with the other limiting gear, such that the different gear ratios causes the one limiting gear to translate over the shaft. At selected travel limits, the one limiting gear is caused to lock relative to the other, thereby causing one of the gears associated with the shaft to shift therearound. A cam structure is provided which axially shifts a stop member associated with the shaft into engagement with a fixed stop when the one gear shifts about the shaft. Two different cam structures are shown including a pin and slot connection between the stop member and the shaft, and an ear and cam recess connection between the stop member and one of the shaft gears.

At its upper end, each blade is pivotally and loosely mounted on an energy absorbing elastomeric sleeve. At its lower end, each blade carries a stop member that projects into the fall path when the blade is in a first ("test") position. The stop members are generally aligned with one another horizontally across the fall path to define a stop surface that precisely locates an integrated circuit at the test site. The device includes an arrangement for repeatedly drawing the lower ends of the blades in unison to a second ("release") position where the stop members are clear of the fall path.
