Patent ES-289151-A1 (ES)
Title: Improvements in and relating to fuel-injection control systems for engines
IPC: F02D41/30
Filed: 1963-06-18
Abstract: In an I. C. engine fuel injection system having an electromagnetically controlled injector, the magnitude of energization is varied to control the stroke of an armature thereby determining the amount of fuel injected. In one embodiment an engine-driven twopole alternator 1, Fig. 3 (not shown) is connected in series with a diode 4 and an injector control electro-magnet 2, regulation being affected by a rheostat 3a controlled by the throttle position. In another embodiment the winding 1, Fig. 4 (not shown) of an engine-driven four pole magnetic flywheel supplies four pulses per cycle and if the circuit includes a diode as in Figs. 3 and 2 (not shown) two impulses per cycle are passed, one impulse being used for ignition through lead 5, the other energizing the electromagnet 2 through transistor 6. A pulse generator 7 connected to the base of transistor 6, is regulated by a throttle-linked rheostat 3 or by an altitude-connecting capsule 9 linked to rheostat 8. Speed regulation is effected by an engine driven voltage generator 10 which charges capacitor 13 through a regulating rheostat 11 and diode 12 to operate by changing the polarity of the base of transistor 6. The pulse generator may be replaced by a double control diode, tunnel diode or single junction transistor. In the embodiment of Fig. 5, a coil 14 applies approximately 300 volts across a rectifier bridge 15 to charge capacitor 16 through resistor 17, the capacitor 16 discharging through controlled diode 18 to injector electromagnet 2 when an impulse is emitted by pulse generator 7. A resistor 19 and capacitor 20 shunted across diode 18 enable the diode to be blocked when the impulse ceases. For speed regulation, when the voltage of coil 14 rises, Zener diode 22 is energized at a value controlled by resistor 23 and current is passed to energize an electrically controlled fuel feed valve 21 to cut off fuel feed. In another embodiment the effect of a vehicle lighting circuit is eliminated by means of a change over switch which places a resistor, having an equivalent impedance in the circuit. Regulation of the injector electromagnet in dependence on throttle position, air pressure or engine speed is effected by movement of plunger cones in inductance coils. In a modification speed limitation may be effected by a circuit including a Zener diode acting on a pulse generator. In a further embodiment a diode in the circuit of the injector electromagnet is separately blocked or operated by separate pulse generators. Alternatively the operating pulse generator is replaced by a tapping from the low-tension supply coil. Current regulation is by means of a saturable inductance coil in which variation of inductance is caused by passage of a direct current which is varied by capacitors linked respectively to an altitude capsule and to the throttle control and by a diode-rectified voltage generator which restricts the engine speed.

Title: Manufacture of elongated articles of noncircular cross sectional shape such as for example twist drills
IPC: B21K5/02
Filed: 1964-01-24
Abstract: A machine for forming elongated articles of non-circular cross-section, particularly twist drills and reamers, comprises a plurality of dies 70-73, Fig. 5, each inclined to the axis of the workpiece 34 and which co-operate together to form in a transverse plane a nip completely enclosing the workpiece, and means for moving the dies substantially parallel with said plane so as to rotate the workpiece and cause the nip to move longitudinally along the workpiece and thus form it into the desired cross-section. In the production of twist drills, high-speed steel blanks 34, Fig. 1, are stacked in a magazine 33 and dispensed individually from the-bottom by a pneumatically operated motor 42, 43. Each blank falls into a funnel 44 leading to a first high-frequency heating station 36, a heat soaking station 37 and a second high-frequency heating station 38. Each heating station comprises a silica-glass tube 41 surrounded by the heating coil. Passage of the blanks through the station is controlled by movable platforms 45- 48 actuated by spring-loaded pneumatic motors 49-52 respectively. To permit ready access to the die station 39, the entire heating and feeding assembly is rotatable about a vertical post 32 which can be lifted by a pneumatic motor 40. The doubly heated blank, when released by platform 48, falls into the die station 39 against a vertical stop 100. It is then engaged with a running fit by a three jaw chuck, 95, Fig. 7 (not shown), actuated by pneumatic motors 92. The dies 70-73, which have flute and land forming edges, Fig. 6 (not shown), are then moved simultaneously in perpendicular directions transversely across the blank to form the flutes and lands, meanwhile the stop 100 has been withdrawn by a pneumatic motor 9.9 and as the dies finally release the blank, Fig. 9 (not shown), it falls against an ejector 97 which discharges it from the machine. The dies 70-73 are carried by slides 59-62, Fig. 2 (not shown), shaped to provide mutual support for each other, Fig. 4 (not shown). They are actuated through pin- and-slot mechanism 101, 102 by a common oscillating member 83 driven by a doubleacting pneumatic motor 85. A pneumatic control system is described, Fig. 11 (not shown), with pilot values actuated by a lug 120 on the piston-rod 84, and an automatic change-over mechanism for the double acting motor 85. The drill blanks are finally heat-treated and ground. Another embodiment is described, Fig. 12 (not shown), for forming a reamer with longitudinal flutes. The dies 70-73 may be curved and mounted for arcuate movement across the workpiece, Figs. 13. 14 (not shown).

Title: Process for the Preparation of a Germanium-Silicon Alloy and Alloys Produced Thereby.
IPC: C30B9/12
Filed: 1966-07-12
Abstract: Germanium-silicon alloys for use in thermoelectric conversion of energy are prepared by melting a mixture of Ge and Si powders together in this presence of a solvent metal at a temperature of not more than 1450 C., keeping the melt at this temperature for sufficient time to ensure homogenization and then cooling it to co-precipitate the Ge and Si and to allow crystals to grow followed by further cooling to ambient temperatures and separation of the crystals and solvent metal. Solvent metals mentioned are As, Sb, Ga, In, Bi, Sn, Pb, Tl, Ag, Au, Zn, Cd and Al. Traces of the solvent metal remaining in the alloy act as dopants and determine its conductivity type. The melting may be carried out under pressure if the solvent metal is too volatile. The solvent metal may be removed by vacuum or chemical treatment or by filtration of the solid crystals from the molten solvent metal. The final alloy may be heated to its solidus temperature in an atmosphere of SiCl 4 and GeCl 4 to obtain slugs of suitable size for thermoelectric use. The melting may preferably be carried out in a crucible of vitreous carbon, beryllia or zinc silicate.

Title: Card reader having card-aligning means and wiping-contact means
IPC: G06K7/06
Filed: 1967-08-31
Abstract: A contact array 38 is movable along an arcuate path to engage a fixed contact array 7 through holes in a punched card DC, the movable contacts wiping the fixed contacts in a first direction, and a stop limits the travel of array 38 towards array 7 whereby the array 38, after engaging the stop, is caused to move parallel to array 7 and wipe the fixed contacts in the opposite direction. Manual insertion of card DC with the correct orientation cams a lever 18 out of the card chamber and closes a first switch in series with a second switch (operated by lever 28 when the card is fully inserted) in the energizing circuit of solenoid 55. Solenoid 55, through linkage 52, 44 rotates a shaft 42 eccentrically mounted in discs 34 which are received in plastics bearings 32. Rotation of shaft 42 causes yoke 37 carrying array 38 to move in an arcuate path towards array 7, pins 47 simultaneously engaging cam surfaces 48 to move yoke 37 axially along shaft 42 so that fingers 51 align the card DC against spacer member 23. Connection is made to external printed circuits by way of tongue 8 which projects through a slot 10 in side wall 3.
