Abstract: A heavy duty door handle and lock apparatus has a housing, a first handle on a first side of the housing, and a second handle on the second side of the housing. The handles are movable independently to retract a latch that extends from the housing. A lock cylinder is provided on one side of the housing. When the lock cylinder is in an unlocked position, both of the handles may be moved to retract the latch. When the lock cylinder is in a locked position, movement of one of the handles retracts the latch but movement of the other of the handles does not retract the latch.

Abstract: A system for monitoring and measuring web applications by a user monitors a web site from multiple points of presence and alerts the web site operator when problems are detected. The system may be used in both corporate intranets and by web site operators. It provides alert information when a web site is not responding, when outages occur, monitors availability, and provides information as to the cause of the problems. The system operates by probing web applications at a chosen frequency from several locations simultaneously, which is called variable simultaneous angulation.

Abstract: A variable alignment window assembly for mounting in a window frame of an enclosure which assembly allows greater light transmission and directional air admission into the enclosure, and which, when opened, may be used to shield out unwanted wind, rain, sun or observation from the outside, may be fabricated from one or more window units, each of which units has two vertically upright window panels angularly sealingly joined together along a common vertical side to form an outwardly projecting window unit having a common apical vertical edge and two vertical sides and means for vertically pivotally mounting, said means connecting a point on said window unit adjacent one of said vertical sides to one side of the window frame such that the unit is pivotable between a closed position, in which the vertical sides of the window are in sealing contact with the sides of the window frame, and an open position in which the vertical side of the unit which is not pivotally mounted to the window frame is outwardly remote
