Patent ES-352423-A1 (ES)
Title: Liquid fuel pumping apparatus
IPC: F02M41/14
Filed: 1968-03-27
Abstract: A piston 23 of a fuel injection pump is hydraulically actuated and towards the end of its discharge stroke, closes the discharge passage 26 to create a hydraulic lock. Discharge ceases when a groove 24 in the piston connects the discharge passage 26 via passage 27a to a spill passage 29 which is gradually closed by the piston 23 as it moves to the right until it is arrested by the hydraulic lock at the same time a relief passage 31 for the actuating liquid is opened by the piston 23 and actuating liquid is returned to source through a pressurizing valve 55. The piston 23 is disposed in a bore in a rotating distributer 11 and during discharge the passage 26 communicates in turn with discharge ports 27 each of which has a suck-back valve 56. The piston 23 is returned by feed pressure applied to each end through the throttle 53, the distance it moves to the left governing the quantity discharged on the subsequent stroke.

D may be of the mono-or dis-azo series which may be metallized, or the phthalocyanine, stilbene or nitro series. The dyestuffs may contain further fluorotriazinylamino groups and also one or more sulphonic acid groups. The dyestuffs are prepared by introducing into an organic non-anthraquinoid dyestuff or dyestuff intermediate, by known methods at least one group of the formula wherein R and R 1 are as defined above, and when an intermediate is used, converting this in known manner into the reactive dyestuff, e.g. by diazotisation and/or coupling, or condensation acylation, reduction, metallization or sulphonation reactions. The fluorotriazinyl group is preferably introduced by reacting a dyestuff or an intermediate containing a group -(Q) n -N(R)H with a compound wherein R 1 is as defined above and X is a radical which is split off as an anion under the reaction conditions. In a further method, dyestuffs containing a fluorotriazinylamino group having X as a substituent on the triazine ring may be reacted with ammonia or with amino, hydroxy or thio compounds to introduce the group R 1 . Many examples are given and the dyestuffs dye hydroxyl group containing textile materials e.g. natural and regenerated cellulose, and nitrogen containing textile materials e.g. wool, silk, synthetic polyamides and polyurethanes in all shades.

Title: Process for concentrating latices by ultra-filtration
IPC: C08J3/02
Filed: 1975-04-24
Abstract: Latices obtainable by emulsion polymerisation of vinyl chloride, optionally with other copolymerisable monomers, are concentrated. Ultrafiltration through a semipermeable membrane made from a synthetic polymer removes water and low-molecular-weight substances dissolved therein from the latex. The membrane should retain substances from a molecular weight of 5,000 to 100,000 and is treated before the ultrafiltration with an aqueous emulsifier solution. This considerably reduces the formation of deposits on the membrane during the ultrafiltration. The pretreatment of the membrane is carried out using emulsifiers as used for the emulsion polymerisation of vinyl chloride.
