Patent ES-294426-A1 (ES)
Title: Transistorized ignition system for internal combustion engines
IPC: F02P7/067
Filed: 1963-12-05
Abstract: Spark ignition apparatus for an internal combustion engine comprises a spark generating circuit for supplying spark-generating pulses to the plugs of the engine in turn a trigger circuit coupled to the spark generating circuit and serving to permit the spark generating circuit to produce a single spark producing pulse each time the trigger circuit is biased by an input, a fixed frequency oscillator providing the biasing input to the trigger circuit and magnetic means driven by the engine for preventing the oscillator from providing the biasing input except when a spark is required. Referring to Figs. 1 to 3, when one of the slots 52 appears between the windings 25, 28 the circuit including the transformer 24 the resistor 29, capacitor 31 and transistor 26 oscillates in known manner to produce an A. C. voltage across the resistor 27. The first effect of this voltage will be to render the transistor 35 conductive. When the transistor 35 conducts current flowing through the resistor 38 can flow through the diode 37 and the collector and emitter of the transistor 35 so that the transistor 42 is cut off. Cutting off the transistor 42 causes a high voltage to be developed in the secondary winding 46 of the ignition transformer and a spark is applied to one of the plugs 48. The transformer 32 causes the current in the transistor 35 to build up by regenerative action until saturation is reached at which point the transistor 35 is switched off and the transistor 42 is switched on again. If the transistor 26 and its associated components are still oscillating a further spark will be produced. Thus at speeds below a predetermined value more than one spark will be applied to each plug. Timing may be controlled by a centrifugal advance mechanism and by a known mechanism which is responsive to the pressure in the air inlet of the engine. If desired the air gap may be of such a size that oscillations are prevented from occurring. In this case, as shown in Fig. 6, the core 49 may be U-shaped and the disc 51 is replaced by a spindle including four magnetic arms 72 which permit oscillations when they pass over the limbs on which the windings 25, 28 are wound. In another modification the windings 25, 28 are wound on the same limb of the core so that they oscillate at all times. However the fixed frequency oscillator is coupled to the remainder of the circuit only when required. Other modifications are described.

Title: Process for the preparation of anhydrous hydrazine
IPC: C01B21/16
Filed: 1966-11-18
Abstract: Anhydrous hydrazine is prepared by irradiating liquid ammonia containing acetone. The concentration of acetone may be between 0À01 and 2 moles per litre and at least one hydrogen atom intercepter in addition to the acetone, such as tertiarybutanol, triphenylmethane or chlo - roform, may be present. Suitable radiation sources'are X-rays, electron beams and gamma-rays from nuclear reactors intensities of 10- 80 Megarads/hour and doses of 100,000-600,000 rads are suitable. Fig. 3 shows a plant in which in section 10, NH 3 is treated with sodium to remove impurities such as A 2 O, O 2 and CO 2 , distilled, liquefied, and mixed with the interceptors in mixer 14 before being passed to the irradiation loop 20. The irradiation is carried out in the cylinder 21, maintained at 86 C, with an electron beam, the liquid being recirculated through the cylinder and through a reservoir 24 in which the gases, N 2 and H 2 , formed are separated. The liquid, after irradiation, is withdrawn and cooled to -78 C. by the two heat exchangers 31 and 32 and the interceptors, which are thus crystallized, are separated in the decanter 33. The mixture of liquid NH 3 and hydrazine is then separated by distillation at 32 C. in the columns 34 and 35 using heat provided by the water, which is heated by transfer with the irradiated ammonia in heat exchanger 31, and the NH 3 is recycled.

Title: Electrical switching apparatus having the armature and contact bridge carrier flexibly coupled together
IPC: H01H45/04
Filed: 1972-08-24
Abstract: Switch gear having an armature and contact bridge carrier flexibly coupled together, with means to prevent relative flexing of the two unless the force on the contact bridge carrier exceeds a certain minimum. The coupling is by means of a pin inserted with play through a bore in the armature and connected to the carrier at its ends. Springs between armature and carrier tend to force them apart to bear on a flat protuberance located in the armature bore. This forces the armature and carrier to a static position as the flat protuberance is disposed on the interior surface of the bore, until the force of the armature overcomes the spring, at which point the linkage can flex.

Patent ES-452155-A1 (ES)
Title: Fault detection for wheel slip control system
IPC: B60T8/88
Filed: 1976-10-06
Abstract: A fault detection system containing three modes of system shutdown, temporary, latching, or permanent disables an automotive wheel slip control system upon detecting faults in the speed sensors, control valves or interconnecting cables. Temporary shutdown is performed immediately following turn on and whenever certain supply voltages drop below threshold levels. Temporary shutdown is automatically terminated at the end of a predetermined time after turn on or when the supply voltages return to normal. Latching, resettable shutdown is performed in response to excessive apparent speed difference between a pair of wheels where the apparent difference endures too long. Latching shutdown is also performed in response to excessive actuation time of one or the other of two wheel slip control system solenoid valves and in response to actuation of a second solenoid valve in the absence of cycling of the first solenoid valve. Reset after latching shutdown is performed by removing and reapplying power to the fault detection system. Permanent shutdown is accomplished when cyclic sensor faults cause spurious operation and when solenoid energization is not terminated by inhibit signals generated during latching shutdown. Reset after permanent shutdown is accomplished by replacement of an external power supply fuse which is blown by the operation of the permanent shutdown function. All fault actuations provide energization signals of an external warning indicator and inhibition of external circuits.
