Title: Fuel injection pumping apparatus for internal combustion engines
IPC: F02M41/14
Filed: 1977-06-22
Abstract: A fuel pumping apparatus comprises a piston movable by fluid pressure to vary the timing of delivery of fuel to an associated engine.

Patent ES-8101519-A1 (ES)
Title: Method of pretreating raw water for reverse osmosis units
IPC: B01D61/04
Filed: 1980-05-14
Abstract: A method of pretreating raw water, for instance sea water, which is intended for supplying reverse osmosis units. An aqueous solution of acid salt and acid with the same anions is mixed with the raw water, whereby the most advantageous pH value is adjusted for the reverse osmosis, and whereby the acid salt is converted into the corresponding hydroxide. After possible addition of flocking or flaking additives, the resulting hydroxide flakes are separated, in a strongly concentrated form, by way of a centrifuge, particularly a plate or disc centrifuge, and together with fresh metal salt, are again brought into solution as a salt by means of the previously mentioned acid and, after mechanical purification in a second centrifuge, likewise particularly a plate or disc centrifuge, are again supplied to the raw water. The pretreated raw water leaves under pressure from the separator through which it flows and, alternatively, a chemical reducing agent may be added to this departing water flow. With a small requirement for metal salts, the recirculation can be eliminated. Also, the addition of the reducing agent to the pretreated raw water can be eliminated.

Title: Isolation of protein and peptide from urine.
IPC: A61K35/22
Filed: 1982-06-02
Abstract: The passage of human urine through a bed of adsorbent material results in the adsorption from the urine of antineoplastic substances as determined by in vitro tissue culture techniques utilizing human tumor cells. The adsorbent yields two antineoplastic fractions upon sequential elution. Elution of the low-molecular weight antineoplastic fraction is accomplished by elution with cold aqueous acetone at slightly alkaline pH. Thereafter, elution of the high molecular weight antineoplastic fraction is accomplished by elution with a cold aqueous acetone-glycerol mixture at slightly alkaline pH. The antineoplastic activities of these fractions are determined by tissue culture techniques employing a variety of human neoplastic cells. Furthermore, the high molecular weight fraction, the antineoplastic urinary protein, also inhibits the progression and causes regression of certain human tumor cells implanted in the nude mouse.

Title: Switching system loopback test circuit
IPC: H04Q11/04
Filed: 1984-02-28
Abstract: This invention relates to a switching system testing arrangement which uses a looparound circuit, into which a test signal is injected and received to determine whether the loop is functioning properly. The system provides means for testing individual switches (or equivalent time division counterpart), individual loops and links between switching stages and the network, complete loops between peripherals, short loops between peripherals and their local control units, or any loop that can be set up within the system, without incurring loss of use of parts of the system which would otherwise be required to obtain the loop but are not of interest to test. The control data and test signals are applied, to set up the loop and into the loop respectively, via message transmission paths which are separate from the loop under test. Accordingly any part of the communication circuit system can be isolated for test, reducing substantially the time overhead for determining whether a switching element or stage, or link is operating properly.
