Abstract: A method for identifying target server computers for consolidating virtual machines in a virtualized data center includes measuring load constraints for different server computers in a virtualized data center. The method also include rendering in a load graph in a graphical user interface (GUI) for the target identification module different icons, each representative of a corresponding one of the different server computers, each icon in the load graph including a position in the load graph according to measured load constraints for a corresponding one of the different server computers. The method further includes selecting a server computer from amongst the different server computers.

Abstract: A method for visualizing and simulating server consolidation of different virtual machines in a virtualized data center can include identifying different server computers in a virtualized data center, computing load metrics for each of the server computers, and rendering a graph of the computed load metrics for the server computers in a graphical user interface (GUI) in a host computer. The method further can include selecting a source one of the server computers and also a target one of the server computers and further selecting a virtual machine for prospective migration from the source one of the server computers to the target one of the server computers. Yet further, the method can include further computing prospective load metrics for the source and the target resulting from the prospective migration of the virtual machine to the target. Finally, the method can include displaying in the GUI respective graphs of the prospective load metrics for each of the source and the target.

Abstract: A shaft is journaled to rotate in a housing and is formed with an enlarged disc which carries an elastomeric ring. As the shaft rotates, the ring is compressed against and is massaged by protrusions extending axially into the housing and coacting with the ring to apply a retarding torque to the shaft. In one embodiment, the protrusions are semispherical buttons which are formed integrally with the end wall of the housing. In another embodiment, the protrusions are spherical balls which are free to spin in semispherical pockets formed in the end wall of the housing.

Abstract: A rotatable shaft carries a hard plastic disc located in a housing. A braking member in the form of a steel washer is sandwiched between the plastic disc and a washer-like elastomeric spring which is compressed against an axially facing wall of the housing. The spring urges the braking member frictionally against the disc to retard rotation thereof and dampen rotation of the shaft. By adjusting a screw, the disc may be shifted axially toward or away from the spring to change the compression thereof and thereby change the retarding torque applied to the disc.

Abstract: The anchor includes a stud holder having one end which threadably receives a threaded stud. A flat tongue-like driving head projects axially from the other end of the stud holder and is formed with an eye for receiving one end portion of a wire tie for establishing a positive lateral load connection between an outer masonry veneer wall and an inner supportive wall having a layer of insulation thereon. An integral, radially extending flange is formed at the inner end of the driving head and stabilizes the stud holder while the latter is being driven by a power-rotated socket. When the stud is fully driven, the flange seals a hole drilled in the insulation by the stud holder. The inner end of the stud holder includes cutting elements which enable the stud holder to drill effectively through both hard and soft insulation. The eye through the driving head is shaped so as to eliminate the need of establishing precise angular alinement between the driving head and the wire tie.

Abstract: The terminal assembly includes a terminal element made of yieldable material and a tubular post made of soft, flowable material. One end portion of the terminal element is defined by a slotted tube-like member adapted to telescope into the post. When the post and the tube-like member are squeezed axially together during assembly, the tube-like member collapses axially and expands radially to cause the soft material of the post to flow into and interlock with the slots and thereby establish a positive electrical and mechanical connection between the terminal element and the post.

Abstract: An assembly for fastening a flexible membrane to a layer of insulation on a roof deck includes a plastic disc and a threaded screw which, when tightened, clamps the disc to the membrane. Angularly spaced pins are formed integrally with and depend from the underside of the disc and bite into the membrane to help prevent edgewise tearing of the membrane when wind uplift forces are exerted on the membrane. The pins preferably are formed between the ends of radially extending and angularly spaced ribs which depend from the underside of the disc to resist upward flexing of the disc.
