Title: Liquid fuel pumping apparatus for supplying fuel to an internal combustion engine
IPC: F02M59/34
Filed: 1969-01-31
Abstract: In a fuel injection pump the plungers 41 are actuated in one direction by multilobed cams 15 and in the other by the pressure of fuel from a feed pump 22 which passes to the cylinders via a throttle valve, 65, Fig.2 (not shown). A groove 81 in each plunger is in constant communication with a groove 61 in the cylinder bore 40 which communicates with a bucket valve 82. The throttle valve 65 is movable in one direction by adjustable springs (72), (73) and in the other by a belt driven centrifugal mechanism 70. On the discharge stroke the plungers spill through ports 59 which may be closed by a manually actuated valve 60 to give excess fuel for starting. Injection is terminated when grooves 84 open to ports 59. Fuel pressure on the delivery stroke forces plug 57 of valve 56 into abutment with a valve body 53 and then valve 56 lifts to permit passage of fuel. Liquid in the delivery line is sucked back when the plug 57 and valve 56 return to their original position. The cam lobes act as bearing surfaces for the shaft 50 and engages the plungers 41, through intermediary tappet rollers 43, provision being made to allow rollers 43 to separate from the cams at the lowermost position of the plungers to facilitate lubrication of the working surfaces. A priming pump 30 is also provided having a hand actuated plunger 31. A bleed 91 is fitted to aleviate build up of gases in the pump.

Patent ES-376204-A1 (ES)
Title: Gating Circuit and Magnetic Store Incorporating the Gating Circuit
IPC: G11B15/087
Filed: 1970-02-04
Abstract: A pulse selecting circuit comprises an input gate receiving the input pulse train, a sawtooth generator having a fixed amplitude flyback and which opens the gate when the ramp exceeds a given level, the generator being triggered by the output from the gate, a further gate receiving the output of the first and being enabled by the ramp generator when the flyback does not pass a given threshold level due to the spacing between the triggering pulses and thus the amplitude of the ramp exceeding a given value. The invention is applied to a train of pulses from a magnetic storage disc, data being represented by pulses D1, Fig. 4a preceded by a clock pulse C and the address by pulses 54, 55 not preceded by a clock pulse. The input circuit comprises a combination of gate 14 and a flyback and ramp generator having a fixed amplitude flyback, described in Specification 1,126,160 and with reference to Fig. 2 (not shown). Briefly, the ramp generator produces an output 4b which, following a clock pulse, provides a gating pulse 4c lasting until the ramp reaches a valve L, the pulse closing gate 14 long enough to block the next data pulse so that only clock pulses and address pulses (i.e. pulses not preceded by a clock pulse) are selected by gate 14, the output of the gate being used to trigger the flyback. The circuit also selects at 15 (Fig. 2) the data pulses. The gating pulses 4c and the selected clock and address pulses from 14 are applied to an AND gate 59 to produce pulses 4d coincident with clock and address pulses. Gates 60 and 63 are crosscoupled to form a bi-stable circuit. It is set by pulses from 14 and reset when the flyback passes threshold L, to produce pulses 4(e). Thus it remains reset during the absence of clock pulses. Gates 68 and 70 also form a bistable circuit. It is controlled by 4e and by the output of an AND gate 66 itself controlled by 4e and the output of gate 14 so as to produce narrow pulses concident with clock pulses and pulses starting at the second address pulse and ending at the next clock pulse 4h. These pulses control a gate 72 which also receives the output of a gate 14 so as to produce pulses coincident with the second address pulse and the next clock pulse (4k). In order to prevent zero drift and pulse timing errors, shown dotted in 4(b), from causing false switching of bi-stable circuit 60, 63, a monostable circuit 74 produces inhibit pulses during this period. The second bi-stable circuit may be replaced by a timing circuit.

Patent ES-407739-A1 (ES)
Title: Rolling mill for flat-rolled products
IPC: B21B31/32
Filed: 1972-10-18
Abstract: The invention is a rolling mill for flat-rolled products designed in a manner to substantially eliminate bending of the rolls under load with associated convexity of the roll gap and resultant tendency towards excess convexity of bar transverse profile. The rolling mill employs the partial cylindrical surface of the roll barrel itself in contact with a corresponding work roll bearing pad, rather than roll neck end bearings, as the main load bearing mill bearings, and supports this bearing against a transversely elongated hydrostatic cushion which distributes the reaction to the roll force uniformly along the length of the work roll. Pressure equalizing cylinders at the roll ends are also used to compensate for bending effects resulting from differences between length of the hydrostatic cushion and width of the bar being rolled. The mill is intended for application to hot and cold rolling of plate, sheet and strip products made of steel, aluminum, copper and like, either in a single stand or in tandem rolling mill applications.
