Patent YU-48339-B (YU)
Inventor: FRANZKE L
IPC: F28G1/16
Filed: 1992-12-18
Abstract: A steam generator with a water lance sprayer for cleaning a surface of a heat exchangers of the steam generator, and more particularly combustion-chamber heat-transfer surfaces in steam boilers, can have an outlet opening swivel-type supported in the wall of the steam generator and its rear parts swivel-type suspended. Such a lance blower is provided with a polydirectional movability in a plane at the outlet opening of the water lance blower without contamination to ensure that the jet meeting the opposite boiler wall describes an exactly defined course. This is done by providing a flange at the outlet opening of the blowpipe, which flange can be attached to a segment of a cardan joint with the cardan joint being fastened in the combustion-chamber wall. The rear part of the blowpipe is preferably arranged in a guide, which guide is vertically shiftable on a vertical spindle, with the vertical spindle being shiftable, at the top and at the bottom thereof, horizontally on a horizontal spindle, and with the guide being formed by a housing that is non-rotatably positioned on the vertical spindle. The guide preferably carries a fork-shaped accommodation containing a cardan-shaped cage which internally is designed as a sleeve for holding the blowpipe in an axially shiftable manner.

Abstract: The present invention provides a digital-based mechanism for adjusting the power consumption in an integrated digital circuit such as a processor. The processor includes one or more functional units and a digital throttle that monitors activity states of the processor's functional units to estimate the processor's power consumption. One embodiment of the digital throttle includes one or more gate units, a monitor circuit, and a throttle circuit. Each gate unit controls the delivery of power delivery to a functional unit of the processor and provides a signal that indicates the activity state of its associated functional unit. The monitor circuit determines an estimated power consumption level from the signals and compares the estimated power consumption with a threshold power level. The throttle circuit adjusts the instruction flow in the processor if the estimated power consumption level exceeds the threshold power level.

Title: Data processing systems with delayed cache write
Inventor: BEGUN RALPH MURRAY
IPC: G06F12/08
Filed: 1989-05-25
Granted: 1991-05-29
Abstract: In a dual bus microcomputer system using a cache memory and a cache controller, the timing requirements placed on non-cache memory components by the cache controller are more stringent than the timing requirements placed on the non-cache memory components by the microprocessor. A logic circuit operates on the cache write enable (CWE) signals, and delays those signals in the event of a cache read miss. Delaying the CWE signals relaxes the timing requirements placed on non-cache memory components and at the same time does not impact wait state parameters for read miss operations.
