Title: Thermostatic mixer with device for dynamic regulation of a water flow
Inventor: KNAPP ALFONS
IPC: G05D23/13
Filed: 2005-11-09
Granted: 2012-05-22
Abstract: The invention relates to a thermostatic mixer, comprising a device for the dynamic regulation of the cold water flow which supplies the mixer.  Thermostatic mixers suitable for control of a large flow do not function correctly when the flow required is much less than the maximum flow for which designed, such as occurs, for example, when a thermostatic mixer for supply of a system with several showers is required to supply a single shower. Under these conditions thermostatic mixers lose stability and begin to oscillate such that the water flow exiting said mixers suffers continuous changes to the ratio of the mixture of hot and cold water and hence suffers temperature variations which are unpleasant for the user and can be dangerous. Said problem can be resolved whereby a resistance is generated to the flow of cold water supplied to the thermostatic mixer, when small flows of mixed water are required and said resistance is lifted or reduced when large flows of mixed water are required. Said operation is automatically carried out by devices for dynamic regulation of flow, whereby the flow cross-section provided for the incoming cold water is reduced when the drawn flow is reduced and a larger flow cross-section reestablished when a larger flow is required.

The composite structures may be constructed of multiple layers of fibers and other materials placed on a fiber placement tool that includes a mandrel body (40) surrounded by a bladder or an integral bladder/caul sheet having expansion spaces created within the caul sheet section. Uncured composite structures may be created by placing fibers around the fiber placement tool in a plurality of discontinuous segments that are capable of moving or sliding in relation to each other so that the uncured composite structure is expandable from within. Fluid openings may be provided in the outer surface of the mandrel body (40) for the application of vacuum and/or fluid pressure to secure the bladder to the mandrel body and to assist in the removal of the bladder from the mandrel body, respectively. Uncured composite structures may be sealed between the bladder and clam shell molds (30, 32). The uncured structures may be expanded against the inner surface of the molds by creating a vacuum between the bladder and molds.

Abstract: The present invention aims to prevent cavitation caused by rapid acceleration at startup of a jet propulsion boat, and, at the same time, aims to improve acceleration performance. Provided is an engine control system that retards the ignition timing when the engine speed rises rapidly at startup of a jet propulsion boat. The engine control system includes a cavitation-control--mode determination unit, which starts a cavitation-control mode when an engine speed not faster than rpm is maintained for seconds or longer. During the normal sailing, the ignition timing is set by a first ignition-timing setting means. After detecting the mode by the cavitation-control-mode determination unit, an engine speed that is raised up to a speed not slower than 3200 rpm makes switching means (ignition-timing setting-means switch unit) select a second ignition-timing setting means. The second ignition- timing setting means retards the ignition timing from the value for the normal sailing when the engine speed becomes 6500 rpm or faster. Along with the switching of the map for the retard of the ignition timing, the boost pressure control command upper-limit value is switched to the value for the startup, which is smaller than the value for the normal sailing.
