Patent ES-465098-A1 (ES)
Title: Cigarette smoke filter
IPC: A24D3/02
Filed: 1977-12-15
Abstract: The filter (1) comprises an air-permeable core (2) surrounded by a wrapping (3) of air-permeable filter paper, corrugated longitudinally along its full length, except for a circular portion (6) at one end (7) of the filter. A non-corrugated wrapping (4) of air-permeable paper surrounds the corrugated wrapping (3), forming longitudinal channels (5) which are closed at one end. This filter efficiently removes carbon monoxide and chemical components of low molecular weight whilst being firm and easy to manufacture on an industrial scale by a continuous manufacturing process, unlike known filters having comparable filtering characteristics.

Patent ES-473829-A1 (ES)
Title: Fuel demand engine control system
IPC: F02D35/00
Filed: 1978-09-29
Abstract: An electrically controlled closed loop system for maintaining a desired air-fuel ratio within an internal combustion engine. An operator-positioned accelerator commands a given fuel flow into the engine and the flow of air is controlled by means of a servo-actuated throttle plate. The commanded fuel flow and present position of the throttle plate are used to generate a basic command signal for controlling the servo motor to adjusting the position of the throttle plate. A gas detector or roughness sensor positioned in the engine is responsive to the actual air-fuel mixture in the engine which may be greater than or less than the desired air-fuel mixture and an error signal is generated which can be used to modify or correct the basic control signal in a closed loop manner for selectively adjusting throttle plate position to more precisely maintain a desired air-fuel ratio. While the present type of system has inherent acceleration enrichment since the fuel enters before the air flow increases, an undesirable condition of excessive enrichment may occur. The rate of change of commanded fuel flow is monitored to anticipate an impending undesirable condition of excessive enrichment and a transient control signal adjustment spike is generated to momentarily increase air flow to minimize the undesirable condition even before the gas detector or roughness sensor actually detects the existence of same. A closed loop governing system for metering the fuel flow may also be provided, if desired.

Title: Clutch mechanism
IPC: F16D13/71
Filed: 1979-06-08
Abstract: In a motor vehicle clutch cover assembly comprising a cover, a pressure plate rotatable with the cover but movable axially relative thereto, and axially-acting resilient means such as a diaphragm located between the cover and the pressure plate and operable to urge the pressure plate away from the cover, the invention provides one or more retaining shims adapted to limit the displacement of the pressure plate relative to the cover, and corresponding apertures in the cover which allow the retaining shims to be removed or inserted. The retaining shims are fitted either during removal of the cover assembly for servicing, or during replacement, and by restricting displacement of the pressure plate reduce the effective axial dimension of the cover assembly thereby facilitating removal or replacement of the assembly in a confined space.
Patent ES-483017-A1 (ES)
Title: Circuit arrangement for driving nonlinear threshold devices
IPC: H04B10/556
Filed: 1979-07-31
Abstract: A nonlinear signal transducer U, such as a light-emitting diode or a semiconductive laser, is maintained at a suitable operating point by a constant biasing current and receives an electrical input signal by way of a series resistor R from a main amplifier AM of variable gain. The output voltage of the main amplifier is detected and integrated to provide a first reference voltage which is compared with the load voltage of the transducer U in a differential amplifier AE1, forming part of a first feedback loop, to adjust a voltage generator GT controlling the output voltage of the main amplifier AM so as to eliminate any voltage drop across the series resistor R as long as the input signal is absent or has an instantaneous magnitude equal to its mean value. A second feedback loop includes a peak-to-peak detector DP which emits a voltage proportional to the signal amplitude, that voltage being compared with a second reference voltage in a differential amplifier AE2 serving to adjust a current generator GC1 which controls the gain of the main amplifier AM. The second reference voltage may be varied manually or in response to changes in the output of the transducer U.
