Patent ES-360292-A1 (ES)
Title: Fuel supply system
IPC: F02M59/34
Filed: 1968-11-15
Abstract: Fuel injection apparatus for limiting the rate of fuel supplied to an I. C. engine to that which it can properly combust at any particular engine speed, comprises a fuel injection pump 26, a speed governed metering valve 19 controlling an orifice 15 in the inlet duct 10, 13, 17, 18, 152 to the pump, and a second valve 20, normally open, but movable to a position limiting flow into the pump only when the metering valve 19 is in the fully open position for the particular engine speed required. Fuel enters the apparatus through a port 2 and is drawn through a passage 7 by a feedpump 8 which delivers to the inlet duct 10.... 152 containing the orifice 15. The size of the orifice 15 is determined by the axial position of the valve 19, urged to the right by the action of centrifugal flyweights 30 driven by the engine. Rightward movement of the valve 19 is resisted by a spring 40 and a substantially constant low-pressure established in a chamber 92. To alter the bias of the spring 40 in accordance with the desired speed of the engine, the spring reacts against a movable abutment 42 acted upon by the pressure of fuel in a chamber 50. The chamber 50 receives fuel from the inlet duct at 18, the fuel passing a port 62 controlled by the metering valve 19 and passages 64, 66, 70. A needle valve 48 positioned by a throttle rod 44 controls an axial spill port 46 in the abutment 42 and thereby both the axial position of the abutment and the pressure in the chamber 50. The pressure obtaining in the chamber 50 is directly proportional to the engine speed and is applied through a passage 98 to a cylinder 100. Thus a piston 102 in the cylinder 100 is subject to a force directly proportional to the engine speed. The piston 102 acts through a lever 108 loaded by an adjustable leaf-spring 108a, Fig. 3 (not shown), to cause opening of a needle valve 114, 5 when the engine speed increases. When the flow through the needle valve 114, 5 reaches the maximum desired level for the specific operating speed of the engine, the so increased pressure differential across the valve causes the downward movement of a diaphragm 128. This results in a plunger 130 restricting an orifice 143 through which feed pressure supplied to a chamber 136 escapes to an inlet chamber 6. Thus pressure builds up in the chamber 136 and deflects a power diaphragm 144 to cause pivoting of a lever 96 and consequential movement of the second valve 20 to a position in which it limits the flow from the duct 152 into the pump 26. In a modification, Fig. 4 (not shown) the operation of the valve 20 is compensated for changes in manifold pressure and temperature.

Title: Method of and apparatus for measuring the distance travelled by a vehicle having a guided path of travel
Inventor: MERTENS PIERRE
IPC: G03B21/60
Filed: 1969-02-04
Abstract: The distance travelled by a train on monorail 1, determined by counting the phase changes produced in a train carried coil as it passes over cross-overs 4 in a current carrying trackside loop 2, 3, is checked by counting the number of "marking" points 5 between crossovers. These points are formed in the arrangement shown, in which the upper leg of the loop is disposed in square waveform, by the transverse portions 5 of the waveform and are detected by the change in amplitude in the signal picked up in e.g. a pair of train carried coils A, B different from the crossover detection coil. Other arrangements of pick-up coil and cable configuration are shown for producing the marking signals.

Patent ES-364091-A1 (ES)
Title: Log feeding apparatus
IPC: B27L1/04
Filed: 1969-02-17
Abstract: In apparatus for moving logs axially, the effective log-engaging centre line between sets of feed units is maintained at substantially the same location. As shown, opposed feed units each have infeed and outfeed sections 11, 12 provided with rolls with vane-like blades 19 which may be stepped on their log-engaging surfaces. The infeed sections 11 are pivotally mounted on shafts 13, 16 and, due to intermeshing arcuate gears 73, 74, it is ensured that both sections 11 move substantially equally and oppositely. The sections 11, 12 pivot about shafts 28 but the degree of pivoting is restricted by abutting framework portions (75, 76), Fig. 5 (not shown). Fluid pressure cylinders 51 may be used to open the sections 11 and compression springs 41 bias the sections 12 together. Drive for the rollers is by an electric motor 61 via belts, pulleys and gears, including idler gears engaged by gears provided on shafts on which the rollers are mounted. In Fig. 1 (not shown), two sets of feed assemblies (10) are used for feeding a log (L) through a ring type debarker (R).

Title: Production of polyamides from aromatic diamines
IPC: C08G69/28
Filed: 1969-07-23
Abstract: A process for producing polyamides comprises reacting a bis(aminophenyl) sulphone with a dicarboxylic acid at 160 to 300 C. in an inert atmosphere and the presence as catalyst of the product formed by adding hypophosphorous acid or its salt with an organic base R-SO 2 -Ar-NH 2 (where R is a monovalent hydrocarbon group or an amino-substituted monovalent hydrocarbon group and Ar is a divalent aromatic group) to the reaction mixture at below 150 C. The acid may be a C 6-16 polymethylene or aromatic dicarboxylic acid. Additives, e.g. heat and light stabilizers, lubricants, fillers, mould release agents and plasticizers may be included. The polymerization may be effected in two stages (i) at 160 to 240 C. under reflux and (ii) at 220 to 270 C. at a pressure of 1 mm. Hg or less. The products are amorphous transparent polymers which can be moulded to fibres or thicker articles without crystallizing. When the acid is aromatic films, fibres and coatings may be obtained from solutions. Examples compare the physical properties, solubility in formic acid, dimethyl formamide or sulphoxide and sulphuric acid and processability of the polymers with those obtained using other catalysts. In several examples the product is a rigid tough foam. Reference is made to Specifications 1,113,824 and 1,161,124.

Title: Fractional current supply
IPC: G05F3/26
Filed: 1974-05-25
Abstract: A relatively small value of current is obtained in an integrated circuit by separating a larger current into two or more parts. The circuit includes two transistors and at least two strings of the same number of series connected diodes. Currents in a fixed ratio to one another are applied in the forward direction to the two strings of diodes and the voltages thereby obtained are applied to the respective base electrodes of the transistors. The larger current is applied in parallel to the emitter-to-collector paths of the two transistors and that part of this current which passes through the one of the transistors drawing the smaller of the two currents, is the current of interest.

Title: Hydrolysis column for an ammonium diuranate conversion line processing system
IPC: C01G43/04
Filed: 1977-05-26
Abstract: A hydrolysis column, used to hydrolyze uranium hexafluoride gas with water in an ammonium diuranate conversion process, which includes a pipe having a water inlet, a connector inserted in the pipe intermediate its length, and a gas nozzle connected to the connector to feed uranium hexafluoride gas into the water. Since the uranium hexafluoride gas will freeze at 147 DEG F, the gas nozzle is heated by steam which flows through internal passageways, thus imparting sufficient heat to the nozzle which then acts as a heat sink to maintain the gas in a fluid state. The gas-water mixture is then discharged through the pipe outlet to the next step in the process.
