Patent ES-418241-A1 (ES)
Title: Transistorized control circuit for magneto motor ignition systems
IPC: F02P1/00
Filed: 1973-08-27
Abstract: An additional winding is provided on the magneto of a magneto ignition system to provide base current, over a capacitor-diode network and a current limiting resistor, to the base of the ignition transistor to assure that the transistor will be switched and held conducting during positive half waves of the magneto output up to the moment of ignition, when a control circuit blocks the ignition transistor. The control winding may be on a magneto armature that serves both to feed the ignition control circuit and to operate as a spark coil, or it may be on an entirely separate armature, or on the lighting system armature of the magneto. Instead of such a control winding, a transformer may be provided in the primary circuit to develop the control voltage.

Patent ES-450199-A1 (ES)
Title: Apparatus for discharging cinders from an incinerator
IPC: F23J1/02
Filed: 1976-07-27
Abstract: An apparatus for discharging cinders from an incinerator has an upwardly open intake pit having horizontally spaced front and rear walls. A water-filled trough is provided below this intake pit and has an upwardly concave floor and defines an upwardly extending outlet for cinders which have been quenched after they have dropped down in the pit into the water in the trough. A stepped plunger has a front face slidable in an arcuate path along the floor of the trough between a retracted position relatively close to the front wall defining the pit and an advanced position relatively far from the front wall. This plunger also has an upper surface on which is provided a step having a face which lies in back of the front wall in the retracted position of the plunger and between the walls in the advanced position. Thus as the plunger is advanced from the retracted to the advanced position the step pushes large objects against the rear wall of the pit and compresses these large objects. In addition, this step is inclined so as to exert a downward component of force on material in the pit and press it against the floor of the trough.
Patent ES-455193-A1 (ES)
Title: Multiple slope ignition spark timing circuit
IPC: F02P5/155
Filed: 1977-01-20
Abstract: A multiple slope ignition spark timing circuit for an internal combustion engine is disclosed which electronically provides a spark timing signal having a piecewise linear advance angle versus engine speed characteristic. A magnetic pick-up sensor produces an AC signal having a frequency proportional to the rotational engine speed. This AC signal is coupled to a programmable voltage slope generator which generates a variable slope voltage that is used to produce the phase difference (advance angle) between a spark timing signal and the AC input signal. An independent timer apparatus produces various timing pulses which result in changing the advance angle versus engine speed characteristic at various predetermined engine speeds. An engine vacuum sensor adjusts the slope produced by the voltage generator and thereby results in a fixed amount of vacuum advance angle being added to the spark timing advance angle versus speed characteristic. The spark timing signals produced by the multiple slope ignition spark timing circuit are then used to ignite the fuel mixture in the cylinders of the internal combustion engine when the pistons are at desired predetermined positions in accordance with the engine speed and vacuum pressure.

Title: Method and apparatus for distribution of glass fibers
IPC: D04H3/03
Filed: 1978-02-15
Abstract: In the manufacture of glass fibrous products wherein gaseous streams of fibers are directed through conduits from a generally horizontal direction downwardly in a generally vertical direction towards a moving collection surface, the improvement wherein forming tubes are telescopically associated with downwardly sloping portions of the conduits and supported so that the forming tubes may be positioned at various distances above the collection surface and at various angular orientations relative to the moving collection surface.

Abstract: A fuel injection nozzle has a valve member biased to the closed position by a spring and a piston housed in a bore connected to the inlet of the nozzle by way of a non-return valve. A space between the piston and valve member is vented to a drain. In order to minimize leakage of fuel, the piston and the bore in which it is located define a groove which is connected to the fuel inlet so that any fuel leaking from the end of the piston subjected to the pressure of fuel at the inlet collects in the groove and returns to the inlet when the pressure of fuel at the inlet falls.
Patent ES-477921-A1 (ES)
Title: Device for measuring concentration of smoke
IPC: G01N21/53
Filed: 1979-02-21
Abstract: The measurement of smoke density from vehicle exhaust is performed as it passes through a venturi. Density is determined by reflecting light through the smoke across the venturi throttle. A smoke head contains venturi passage for the smoke around which a light source is located to direct light across smoke to be reflected at venturi throttle. A filter and fan ensure that clean air enters a chamber containing the smoke head. An air heater is mounted on this chamber to prevent condensation occurring on the light reflector.
