Abstract: Continuous prodn. of random copolymers (I) of propene with other monoalkenes is carried out in the qas phase in the presence of a Ziegler-Natta catalyst system at 50-80 deg.C and 20-35 bar in a centric stirred bed of small polymer particles with a Froude No. of 1-3, in which the heat of polymerisation is removed by evaporative cooling. The monomer mixt. is supplied and (I) is discharged from the polymerisation zone continuously or cyclically. The process is carried out under conditions such that: (a) the polymerisation zone is kept in a pressure and temp. range at which the monomer mixt. is gaseous; (b) the unpolymerised monomer mixt. is discharged as gas, liquefied, stored and recycled to the polymerisation zone in liq. form; (c) the temp. in the polymerisa-tion zone is controlled by monitoring the temp. continuously and varying the amt. of liq. monomer mixt. introduced in unit time, which vaporises in the reactor; and (d) replacing the polymerised monomers by supplying fresh monomers. The novelty is that the monomer mixt. used contains 0.5-3.5 mole-% ethylene and 0.2-1.0 mole-%. H2 w.r.t. propene nand the dwell time of the monomer mixt. in the polymerisation zone is 0.5-8 min.

Abstract: The specification discloses a method for the preparation of a bland, keepable marine oil/vegetable oil which does not contain hydrogenated marine oil. The blend will retain its blandless for at least three months without development of a "fishy" odour and can be used for frying, baking or the preparation of edible compositions such as margarine. The result is achieved by blending the oils during or shortly after a refining process and overcomes the long-standing requirement that marine oils should be hydrogenated before use in edible compositions.

Abstract: Processes characterized by dissolving a dye in a solution of organic solvent and an epoxy resin type polymer, which requires a curing agent in order to create a resultant nanosphere that will crosslink through the action of the curing agent, and not simply as the result of a solvent removal which defined each nanosphere. The dye may be in a concentration range of 1% to 50% by weight of solvent, and the organic solvent must have limited solubility in water, typically less than 20%. An initial intermolecular mixing step dissolves dye and epoxy resin within a solvent so as to make a homogeneous solvent/polymer/dye intermediate mixture, that then is dispersed as nanoparticles in water, and thereafter crosslinked. Surfactants may be used to assist in dispersing the dye/polymer/solvent solution into the water continuous phase.

Abstract: A two-stage process for purifying wastewater containing organic and adsorbable pollutants includes the steps of first aerating the wastewater in the presence of a powdered adsorbent, such as activated carbon, and biologically active solids in the aeration zone of a primary treatment zone (10) which also includes a quiescent zone (14). The thus-treated water passes from the aeration zone (10) to the quiescent zone (14) where it is retained a sufficient time for a substantial portion of the suspended solids to settle by gravity. The partially-treated wastewater overflowing from the quiescent zone (14) is introduced into one or more contact zones (30) wherein it is agitated, preferably by aeration, in the presence of a powdered adsorbent, agitation is terminated and the solids are allowed to settle by gravity and, after completion of settling, clarified, substantially solids-free water is withdrawn from each contact zone.

Abstract: In an injection device for diesel engines, in particular in a pump nozzle (1, 41), in which the fuel is conveyed by a pilot pump (32) into an intake chamber (13, 51) which can be connected to the working chamber (9) of the injection pump piston (3) by way of at least one control hole (8) in the pump piston sleeve (7), the conveying end (i) of the injection pump piston 3 being determined by controlling the fuel through the control hole (8) or control holes into the intake chamber (13, 51), at least one displacement piston (17, 46) carried in a cylinder (21, 47) and driven to produce a reciprocating motion is provided, whose working chamber (23, 49) is always openly connected to the intake chamber (13), the displacement piston (17, 46) reducing its working chamber (23, 49) before the start of pumping (h) by the injection pump piston (3) and enlarging it on or after the completion of pumping (i) by the injection pump piston (3). In this way the fuel pressure in the intake chamber (13) is raised before the start of pumping (h) by the injection pump piston (3) and improves the filling of the working chamber (9) of the latter. When, on completion of pumping (i), the fuel emerges from the working chamber (9) of the injection pump piston (3) through the control holes (8) with great energy into the intake chamber (13, 51), the admission volume of the intake chamber is increased due to the increase in the working chamber (23, 49) of the displacement piston (17, 46), thereby reducing the force of the resulting pressure spray. <IMAGE>

Abstract: The carrying line (5) on which a person can be suspended by means of a safety harness is lowered or raised in a controlled manner via the cable drum (1). The endless drive cable (16) running over the drive wheel (15) serves to control the movement. The lifting is effected by the suspended person pulling on one side of the cable, by the control and drive mechanism (12) via the reduction gearing (14), whereas the friction coupling between the drive wheel (15), the notched wheel (21) with the friction linings (210, 211) and the flange sleeve (20) of the main shaft (2) is released by pulling on the other side of the drive cable (16), and the controlled and braked lowering is effected by the drive cable. When the person lets go of the drive cable (16), full braking is immediately effected. The catches (24) engaging in notches (22) provide a safeguard against return travel during lifting. The device can be used for any activity on perpendicular walls or masts where secured suspension from the topmost part is possible. The advantage consists in the fact that the person fastened to the device can move up or down without an additional aid and can be secured and can work with both hands when stopped. <IMAGE>
