Title: Liquid fuel pumping apparatus
IPC: F02M41/14
Filed: 1967-05-30
Abstract: In a distributer type fuel injection pump having cam actuated plungers 12, a piston 21 loaded by a spring 24 and loosely disposed in a cylinder 20 is disposed in each of the outlets 17, the cylinder forming part of the flow passage to the line 18. The cam 13 is so shaped that after the end of each delivery stroke and whilst communication between the injection pump passage 15 and an outlet 17 is still established, a limited movement of the plungers in the filling stroke direction can occur followed by a rest period during which the connection between the passage 15 and outlet 17 is broken, whereby pressure at the outlet is relieved. As shown the piston 21 engages an abutment 33 in the rest position and the cylinder has ports 22, 23 communicating with the line 18. In a modification Fig.2 (not shown) the abutment is replaced by an annular valve seat on which the piston closes and the cylinder bore is enlarged to provide communication with the line 18 and is formed in a member with an end cap abutment for the spring 24 in place of the unitary member shown in Fig.1.

Title: Movable loading and unloading device
IPC: B60P1/64
Filed: 1968-05-03
Abstract: A vehicle load platform 3 has at each end a tubular support or jib 5 pivotally mounted on the medial plane. Pistons 6, 7 extend between a bearing-plate 11 at the top of the jib and shoes 13, 14 slidable on supporting bars 8, 9 pivoted on the edges of the platform. The free ends of the bars carry pivotally mounted supporting shoes 15, 16. To unload the platform the pistons on one side are extended to pivot the corresponding supporting bars until their shoes engage the ground while the other bars are retained locked in their vertical position and thus support the vehicle on the side unloading is to occur. With the load secured to or between the bearing members 11 the other pistons are now extended to swing the load in a circular path about the ground-engaged shoes until it is free of the side of the vehicle when the pistons on that side are retracted to lower the load to the ground.

Patent ES-368668-A1 (ES)
Title: Transmission of information between elements in relative motion
IPC: G08C17/04
Filed: 1969-06-21
Abstract: In an automatic alarm for use in a motor vehicle, the direction of feedback in a circuit 20, preferably mounted on the vehicle chassis adjacent a wheel, is reversed to make the circuit oscillate by an inductive loop 10, preferably mounted on the wheel, when loop 10 is adjacent oscillator 20 and a switch 13 is closed in response to an alarm condition, e.g. pressure and/or temperature. In an alarm condition, oscillator 20 thus produces a burst of oscillation once per revolution of the wheel. Oscillator 20 turns on a Darlington pair 33, 34 and hence a Darlington pair 45, 46 to operate a visible and/or audible alarm 49. Alarm 49 is maintained in continuous operation by a capacitor 50 and a diode 47. Alternatively, the pair 45, 46, may be replaced by a thyristor. The supply to oscillator 20 is maintained constant by a diode 37 and a capacitor 36. A loop 10 may be provided for each vehicle wheel and the associated oscillators 20 may be connected to a single alarm on the vehicle's dash-board (Fig. 6, not shown). Alternatively, a single oscillator may have several feedback paths, each associated with a loop 10. A loop 10 is formed as conductive spirals printed side-by-side on one or on opposite sides of a circuit board (Fig. 3, not shown) which may be insulatively coated and integral with means for actuating switch 13. Switch 13 may be actuated by a pressure-sensitive device (76) flexibly connected to a tyre inflation valve (74, Fig. 7, not shown). Oscillator 20 and Darlington pair 33, 34 are embedded in an insulative mass (30, Fig. 5, not shown) with two projecting electrical terminals 31, 32 being used to mount oscillator 20, earthing terminal 32 having a screw-thread, and terminal 31 an insulative spacing collar.

Title: Integrated buffer circuits for coupling low-output impedance driver to high-input impedance load
IPC: H03K17/567
Filed: 1970-09-08
Abstract: The combination in a common substrate, of a lateral bipolar transistor operated in the common base mode and a field-effect transistor whose source (or drain) electrode is the collector electrode of said bipolar transistor. A signal applied to the emitter of the bipolar transistor causes a current to flow through the conduction channel of the field-effect transistor. The voltage thereby developed at the electrode common to both transistors, even in response to a small signal current, is of sufficient amplitude to drive a high-input impedance load such as other field-effect transistors embedded in the same substrate.

Title: Prevention of coking in pyrolysis plants
IPC: F28F19/00
Filed: 1970-11-17
Abstract: Coke obstructions are prevented in pyrolysis plants by causing the coke to deposit on a sieve in an easily accessible position in the flow path of the cracked gas stream between the pyrolysis furnace and the cooler. The sieve may comprise one or more wire mesh cages, preferably two disposed one within the other, the inner having a larger mesh size than the outer. In the example the cracked gases contain about 33 mole per cent ethylene obtained by pyrolysis of ethane. When the resistance of the sieve to the gas flow increases due to coke deposition the sieve is replaced.

Patent ES-396505-A1 (ES)
Title: Rapid charging system and method for sealed storage cells
IPC: H02J7/04
Filed: 1971-10-29
Abstract: A system and method for effecting rapid safe charging of sealed storage cells embodying a charger to supplying a rapid high rate charging current to the cells or battery of cells with interruption but once during charging, at an optimum time to prevent cell or battery damage, the timing of this interruption being effected by change in magnitude of a continuous control signal by means incorporated in the cell or battery. This magnitude changes when voltage across the cell terminals increases above a reference voltage that varies with change in battery or cell temperature, the change in said magnitude of the control signal serving to effect interruption of rapid charging. Subsequent to this interruption charging at a slower rate proceeds to complete the charge of the sealed cell or battery of such cells.
