A fitting for providing a substantially fluid-tight seal between an opening in a chamber wall and a pipe passing through the opening, the fitting including a tubular sleeve adapted to pass through the opening in the chamber wall and further adapted to allow the pipe to pass through the sleeve, a flange extending radially outwardly from the sleeve, a first surface of the flange being configured to contact the chamber wall around substantially the whole circumference of the opening wherein the fla...

A system for sharing an interface between objects is described herein that saves significant mounts of system resources, such as memory, in an object oriented system. The interface shared by the system described herein is an interface containing methods that perform a drag and drop operation. In addition, since one instance of the interface is shared among multiple objects, the system centralizes the processing performed by the methods of the interface. This centralization includes centralizing ...

A device and method for increasing integrated circuit density comprising at least a pair of superimposed dice, wherein at least one of the superimposed dice has at least one bond pad variably positioned on an active surface of the die. A plurality of lead fingers from a leadframe extend between the dice. The leadframe comprises at least one lead with leads of non-uniform length and configuration to attach to the differently positioned bond pads of the multiple dice. An advantage of the present i...

A retainer for preventing dislodgment of a shaft from a bearing including a radially expandable retaining ring, a circumferential groove in the shaft having a frustoconical side, and a frustoconical sidewall on an inner race of the bearing facing the frustoconical side of the groove in the shaft and cooperating therewith in defining an annular V-shaped retaining ring groove. In a seated position of the retaining ring in the retaining ring groove, the retaining ring is wedged between the frustoco...

A method for selectively pre-fetching Line M+1 into an L1 instruction cache from an L2 cache or from main memory during the execution of Line M. If unresolved branches exist in pending Line M, Line M+1 is speculative and may be pre-fetched into L1 instruction cache only from L2 cache, not from main memory. Unresolved branches in pending Line M are resolved before Line M+1 is pre-fetched from main memory. If no unresolved branches exist, Line M is committed ("inevitable-speculative") and is pre-f...

A submarine connection apparatus for avoiding the necessity of raising to the surface the means used for connecting two submarine conduits. A unit 40 comprising two connectors 7 and 11, which are already connected together by a flexible element 32, are lowered above the first conduit 15 to be connected. The unit 40 is guided by the structure 35, a stop 14 of which strikes the sliding element 13, releases the ball-bearing 41 and enables the connector 11 controlled by the pressure of rim 9 of unit...

Interplane connectors (vias) between circuit layers are fabricated by providing a metal base plate with the desired connectors thereon, forming the connectors at right angles to the base plate and embedding the connectors in a plastic matrix. The base plate is then removed, leaving the plastic with the connectors embedded therein at the desired locations.

A connection diaphragm is provided for articuately connecting long multi-deck railway vehicles constructed in sections so that said vehicles are capable of negotiating curves in trackage along which said coupled vehicles travel. The diaphragm comprises a pair of units telescopingly and pivotally connected to the adjacent ends of a pair of coupled articulated railway car sections so as to telescope inwardly with respect to an associated section upon buff contact and also to pivot when the cars ne...

A joint between drive and driven shafts necessitating alignment therebetween comprises a first and second flanged socket adapted to rigidly retain therein a drive and driven shaft respectively. A disc of resilient material is located between the flanged sockets and is rigidly connected thereto. The disc has means on its outer periphery to radially restrain outward movement of the disc. A self-aligning bearing is located between the annular disc and the first flanged socket. The annular disc and ...

A mold for forming joints between a pair of pipes, such as sewer pipes extending into a man hole, where the mold includes a pair of mold parts extendable into the interiors of the pipes and having on first ends interengagable means for joining the mold parts together at one angular orientation and having on second ends interengagable means for joining the mold parts together at a different angular orientation so that one set of mold parts may be used to form joints between pairs of pipes in eith...
