Abstract: To provide a structure for attaching exhaust control valves near exhaust ports in a two-cycle engine, the exhaust control valves variably controlling open areas of the exhaust ports. The cavity for receiving the exhaust control valves is formed near the upper edges of the exhaust ports on the cylinder block. The holder member is interposed between the cylinder block and the exhaust manifold, is attached to the pivot for supporting the exhaust control valves. A flange is provided for connection with the cylinder block. Therefore, the exhaust control valves are disposed near the upper edges of the exhaust ports. It is not necessary to form bearings on the cylinder block using a complicated process. Complicated parts such as bearings are collectively formed on the holder member that is independent and compact and easily machined. The pivot extends across the exhaust passages that are formed downwardly in order to detour around the pivot. A jet-propelled boat is provided with a saddle seat in which the power unit is neatly and compactly arranged in a limited space.

Abstract: A method for transmitting digitally coded data of a radio program (A) is proposed, in which the digitally coded data are modulated by a modulation method, in particular by OFDM. The data are modulated to at least one carrier wave. The data are transmitted in a transmission frame. The method is characterized in that the data of a radio program (A) are transmitted, with at least one repetition, and then are evaluated in common. In this process the complex values (20, 21), which have been furnished by the demodulator circuit (53), are added together. For a device for receiving digitally coded data of a radio program (A), it is proposed that in it, not only an high-frequency conversion stage (51), an analog/digital converter (52) and a demodulator circuit (53) but also a buffer memory (57) are provided, in which buffer memory at least the data of the time segment of the radio program (A) upon the initial transmission are buffer-stored, and finally an adder stage (58) is provided, in which the data in the buffer memory (57) are added to the corresponding data upon the repeat transmission of the radio program (A) (Fig. 5).

Abstract: The present invention provides a method for reducing the amount of water produced from a subterranean formation as a result of stimulation of the subterranean formation. The method comprises the introduction of a first and second reactive polymer which leak-off into the formation and which are capable of subsequently reacting together to form a reaction product which selectively reduces the permeability of the formation to water flow through the formation. The reactive polymers react in situ to form a reaction product that binds to the formation in such a manner that the flow of water is selectively retarded through the matrix while the flow of oil is substantially unaffected.

Title: Computer system and computer implemented process for representing software system descriptions and for generating executable computer programs and computer system configurations from software system descriptions
Inventor: MALONE THOMAS
IPC: G06F9/44
Filed: 1997-03-19
Granted: 2004-06-01
Abstract: A computer software system includes interdependent collections of software components. That is, at the architectural level, software components and their interdependencies are two distinct equally important entities. The software components represent the core functional pieces of an application and deal with concepts specific to an application domain. Interdependencies relate to concepts orthogonal to the problem domain in most applications, such as transportation, sharing of resources and synchronization constraints among components. An architectural description language which represents activities and dependencies between activities as separate entities. Dependencies are managed by coordination processes associated with the dependency. Activities and dependencies are connected through ports which encode interfaces between activities and coordination processes. The language may also represent resources which may be understood as the output of some activity beyond the scope of the system. Each entity, i.e., activity, dependency, port or resource, may also have attributes which are name value pairs, specifying additional information about the entity.  Attributes may be inherited. That is, activities and dependencies may be specialized into particular versions of an activity or dependency. The attributes for a particular activity are inherited by its specializations. An editor repository and design assistant may be based on this language to provide a system that automatically generates executable code.

Granted: 2009-12-15
Abstract: A controller for a variable-speed induction motor includes field-oriented control, which is a feedback arrangement senses motor parameters to form field and torque error signals. The field error signals are processed by a first limited-state PI processor, which individually limits the magnitude of the proportional component of the field voltage to no greater than the bus voltage. The field error signals are also processed by a state-limited integrator which limits the integral component of the field voltage to the difference between the proportional component and the bus voltage. A first summer sums the proportional and integral components to make the field voltage command. The torque error signals are processed by a further limited-state PI processor which individually limits the proportional component of the torque voltage to a value not greater than the available bus voltage, after the first PI processor has been given preference. The integral component of the torque voltage command is generated by a second state-limited integrator which limits the integral component of the torque voltage command so that the torque voltage command does not exceed the available bus voltage. A second summing circuit sums the proportional and integral components of the torque voltage command. The field and torque voltage commands are processed to produce the desired motor flux and torque, and a feedback loop forces the motor current to follow the commanded values.
