Patent ES-465765-A1 (ES)
Title: Rotary distributor fuel injection pump
IPC: F02M59/20
Filed: 1978-01-04
Abstract: The disclosed liquid fuel injection pump is suited for the delivery of measured charges of liquid fuel under high pressure sequentially to the cylinders of an associated engine and includes a free piston type plunger reciprocably mounted in a pump chamber, wherein the charges are pressurized to high pressure, a stop for the pump plunger to limit the maximum volume of the chamber, a hub mounting a plurality of rollers to engage the camming surface of a tappet interposed between the plungers and the rollers to drive the pump plungers in a direction to reduce the volume of the pump chamber, and hydraulic means to power said pump plunger in the opposite direction. The hydraulic means includes a passage containing fuel under pressure in continuous communication with the pump chamber with a one-way valve in the passage unseated by the pressure therein after the release of the pump plunger by the rollers to hydraulically power the plunger against said stop and fully charge said pump chamber prior to each pumping stroke of the pump plunger, the tappet being mounted by a timing piston to shift the timing of the pumping strokes according to engine operating parameters. A spill metering system is disclosed with the spilled fuel being stored in an accumulator to supply the fuel for the succeeding pumping stroke. The hub is hollow and mounts Z-shaped flyweights so that they are insensitive to shock forces and have a rate of increase in their rotating moment substantially less than a square function of speed to provide, in cooperation with a unique pressure regulator, a control pressure for the governor and timing functions of the fuel injection.

Title: Cylindrical capsule assembly esp. for liq. pharmaceutical prepn. - has cap fixed to body with annular zone of sealing compound
IPC: A61J3/07
Filed: 1978-03-29
Abstract: The capsule comprises a hallow, cylindrical body with one open end which is fitted with a closure cap. The internal surface of the cap is bonded to the body by a viscous sealing cpd.

Application of sealing cpd. can be made before or after the cap is pushed fully home on to the body. The sealing cpd. can be material of the cap or body itself softened by localised heating where sealing is required. Used as a hard-shelled, cylindrical capsule o contains a viscous material, esp. a liq. pharmaceutical compound. A completely leak-proof capsule can be filled without difficulty on the premises of the pharmaceutical mfr.

Title: Centrifugal cleaner apparatus and canister type arrangements thereof
IPC: B04C5/28
Filed: 1978-05-03
Abstract: A cleaner package for receiving materials a constituent or constituents of which are to be separated and/or cleaned includes means defining an inlet chamber and an outlet chamber which are axially spaced and have at least one centrifugal cleaner unit interposed therebetween.

Patent ES-471825-A1 (ES)
Title: Two-group/simultaneous full injection conversion system for multiple cylinder engines
IPC: F02D41/10
Filed: 1978-07-18
Abstract: An electrical fuel injection system incorporates electromagnetic injectors wired in two groups and which are operated on alternate cycles during low speed and normal operation. With increasing power demands, the fuel injection computer supplies pulses of increasing length to keep the injectors open longer and supply more fuel to the engine. Two trains of timing pulses are initiated by reed switches operated by the distributor, and each is connected to a pair of latch circuits operative to provide timing pulses on one channel through gate devices to one set of injectors and to block pulses on a second channel to the other set of injectors. The subsequent signal from the other reed switch results in a timing pulse in the second channel. These timing pulses are supplied to the fuel injection computer to initiate the injection pulses and to AND gates which also receive the timing pulses. Under high power demand conditions, an injection pulse may become longer than the time interval between the two trains of timing pulses, and hence a timing pulse is overlapped by an injection pulse from the opposite switch. When this happens, the associated AND gate provides an output pulse to one of two additional latch circuits to cause this latch to provide an output effectively blocking one of said channels and switching additional gate devices to enable both channels to be energized simultaneously by the injection pulses in the second channel. The length of the injection pulse is also measured by any of a plurality of disclosed devices such that when the pulse length drops to approximately 40% of the duty cycle, an output is provided which resets said additional latch circuits to cause said circuits to switch back to two-group operation.

Title: Apparatus for converting concentrated solar energy into heat energy
IPC: F24S23/30
Filed: 1978-09-20
Abstract: Situated in the region of the focal line of an elongate liquid lens (22) are two concentrically arranged pipes (36, 38). The outer pipe (36) is transparent and the inner pipe (38) absorbs the concentrated solar radiation incident upon it. Both pipes are arranged in a cutout (44) of a collector (24). The collector is connected to the liquid lens by a frame linkage (30, 50, 66). The frame linkage is pivotable about two axes (52, 60) in order that the liquid lens can track the position of the sun. The liquid lens comprises a lower plane transparent plate (28) and a curved transparent plate (26). Situated between the plates is a liquid (31) which lets the solar rays through. A liquid, which has a lower boiling point than the liquid which is guided through the inner pipe, is guided through the outer pipe. The liquid in the outer pipe serves for hot-water preparation while the liquid in the inner pipe serves for preparing steam.

Title: Separating function control method for an electrostatic separator, and control apparatus therefor.
IPC: B03C3/68
Filed: 1983-09-01
Abstract: Method for controlling an electrostatic separator in a controlled separating function using a closed-loop controller and a control component by reducing the control angle during the phase control of the alternating supply voltage by means of a thyristor actuator, the reduction of the control angle alpha being carried out in the direction of zero delay-anglesetting starting from zero operating voltage when starting up the electrostatic separator (A) or when interrupting the direct operating voltage during the separating function or even starting from a direct operating voltage which is partially reduced during the separating function, and is carried out from half wave to half wave of the alternating supply voltage u and is maintained in each case up to a half wave in which the triggering of the thyristor actuating element (St) by a control pulse does not occur the first time and then the reduced control angle is reset to the earliest possible ignition time tn of the thyristor actuator. A control device for carrying out the method contains a comparator (K) which detects the current cut-in of the separator current IA each time the thyristor actuating element is actuated and indicates the absence of triggering to the closed-loop controller (11) via a digital output, as a result of which the resetting of the control angle alpha to the earliest possible ignition time is brought about.
