Patent ES-397795-A1 (ES)
Title: Dredging head with pivotally mounted mud shield
IPC: E02F3/92
Filed: 1971-12-09
Abstract: A dredging head with a pivotally mounted mud shield and cooperating intake assembly. A head located at the end of a dredge boom has digging and conveying screw augers attached to a rotating shaft to loosen material such as mud, silt, and weeds from the bottom of a body of water and convey it toward an intake assembly which includes a suction intake conduit, a rotor, a stationary anvil, and an arcuate bar assembly. The mud shield confines material near the augers so the material can be conveyed by the augers to the rotor, stationary anvil, and arcuate bar assembly which cooperate to cut and shred the dredged material as it is pulled into the suction intake conduit. The arcuate bar assembly reinforces both suction intake conduit and stationary anvil and provides support for the rotor to prevent shaft deformation if collision with an underwater obstruction flexes the shaft against the arcuate bar assembly.

Patent ES-481821-A1 (ES)
Title: Closed loop system
IPC: F02D41/14
Filed: 1979-06-22
Abstract: A closed loop system for the control of the air/fuel ratio of an internal combustion engine is disclosed. The system includes an open loop air/fuel ratio controller that has a closed loop correction applied to its basic pulse width control signal. The closed loop correction is based upon the bi-level switching of an oxygen sensor detecting a substantially stoichiometric condition in the exhaust gas of the internal combustion engine. Performing the correction is an integral controller which responds to the switching of the exhaust gas sensor to increase the air/fuel ratio for one level of the sensor and to decrease the air/fuel ratio for the other level. The limit cycle oscillation developed by the integral controller is modified by increasing the authority and gain rate of the controller as a function of the distance the system is away from a reference point so that it responds to transient conditions rapidly and smoothly. Another aspect of the invention provides for the authority modification to take place when the controller reaches a threshold and to employ minimum constant authority for quiescent conditions. Also, in response to a closed throttle or idle condition the quiescent authority level is reduced to a convenient idle level to prevent torque roll.

Title: Resonant electroacoustic transducer with increased band width response
IPC: G10K11/02
Filed: 1980-07-22
Abstract: An electroacoustic transducer which includes a vibratile diaphragm operating at resonance has its narrow band width response characteristic increased by an order of magnitude by the use of a uniquely designed acoustic coupler in combination with the resonant diaphragm. The acoustic resistane presented to the resonant diaphragm by the acoustic coupler dominates the motional impedance characteristic of the transducer in the resonant frequency region of the vibratile diaphragm. The use of the inventive acoustic coupler reduces the Q of the vibrating system from a value in the order of 30 or more to the order of 8 or less.
