Title: Device for adjusting a movable electro-acoustic sound transducer
IPC: H04R1/08
Filed: 1981-03-10
Abstract: In a device for adjusting a movable electro-acoustic sound transducer, an optical duct is connected to the sound transducer which only allows an object, such as a display table or a data display unit, to be viewed completely in one specific position. This position is unambiguously reproducible and so is the position of the sound transducer or microphone relative to the mouth of the speaker. The optical duct may comprise diaphragms or a tube, possibly with intermediate walls, or a phase amplitude grating. The object may be a display unit and the device further comprises a device for generating variable data on the display. If used for speaker identification, the variable data generator projects consecutive instructions on the display so that, the speech recognition process is controlled automatically. The speaker to be identified is then required to keep his mouth in the correct position relative to the microphone.

Patent ES-8400806-A1 (ES)
Title: Free vortex pump.
IPC: F04D29/22
Filed: 1982-11-29
Abstract: The free-flow pump has an impeller housing (9, 10) laterally of its free flow chamber (4), and the impeller (6) is located in the impeller chamber (9, 10). The external, radial limiting member (10) of the impeller housing is drawn forwardly into the free flow chamber so as to decrease in the direction of rotation from the housing tongue (11) to the pressure pipe outlet. The limiting member (10) causes a constriction in the external portion (4') of the flow chamber, and such constriction decreases from the housing tongue towards the pressure pipe outlet. These measures permit the pump characteristics to be improved, and in particular the throttle characteristic of the free-flow pump can be stabilized.
Patent ES-8404465-A1 (ES)
Title: Retarding system of a gas compression relief type.
IPC: F01L13/06
Filed: 1982-12-24
Abstract: A hydraulic reset mechanism is provided for an engine retarder of the compression relief type. The mechanism includes a pin valve and senses the force required to hold open an exhaust valve. When this force has decreased substantially from the force required to open the exhaust valve initially, the pin valve is opened in the hydraulic system to release the hydraulic pressure and permit the exhaust valve to close. The mechanism thereby assures that the engine exhaust valves are closed, or substantially closed, prior to the normal opening of the exhaust valves at the end of the power stroke of the engine without affecting the retarding horsepower produced by the engine brake.
