Abstract: PROBLEM TO BE SOLVED: To keep a high quality of an aqueous dispersant contained in a storage tank for a long time and prevent biodegradation and damage of equipment resulting from the biodegradation, by adjusting to keep the delivery opening at almost the water level when charging water by use of such a conduct pipe that the delivery opening follows up the level change near the water face. SOLUTION: A charging pipe 1 of a storage tank 7 is connected to a floating pipe 2 provided with a plurality of rotary joints 3. A float 4 is fitted to the end of the floating pipe 2 and a delivery opening 5 is positioned a little lower than the water level 6. The bottom of the water storage tank 7 is inclined to conduct water to a discharge pipe 8. In this constitution, fresh liquid is charged to the nearby position of the surface on charging it and the liquid held for a long time is taken out from the storage tank 7 through the lower discharge pipe 8 on discharging it. In this way, an additional equipments cost for agitation can be reduced and at the same time, the aqueous dispersant stored in the tank is prevented from excessive aging and the high quality is retained for a long time.

Abstract: Readily filterable and deodorizable aqueous dispersions of pressure-sensitive adhesive, especially for self-adhesive labels, having solids contents of more than 65%, can be prepared with readily reproducible properties by copolymerizing esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm of inhibitor and, preferably, in the presence of from 0.01 to 5% by weight of reducing agent by a special emulsion technique. The highly concentrated pressure-sensitive adhesive dispersion, subsequently deodorized with steam, is free from coagulum and seediness.

Abstract: A stuffing box has a screw connector (5) or seat containing a lubricant-filled chamber (8, 9) surrounding a slide. A stuffing box, with a lubricated screw connector or seat for compressing the stuffing, has a lubricant-containing chamber (8, 9) which surrounds a slide and which is formed in the screw connection (5) or seat above the stuffing. Independent claims are also included for the following: (i) a pipeline system equipped with the above stuffing box; and (ii) a method of maintaining relative motion between a moving slide and a stuffing box by providing a lubricant in an open chamber (8, 9), completely surrounding the slide with a lubricant film in the chamber and applying the lubricant film onto the slide surface during relative motion. Preferred Features: Lubricant is supplied from a lubricant reservoir (18) to the chamber (8, 9) through the screw connector (5) or seat or through a closure (1) of the screw connector or seat. The closure (1) has one or more scraper elements (16) which are O-rings located in a recess along the slide movement direction. The slide is a plug retainer, a plug holding mandrel or a T-ring slide. The lubricant may be a water-insoluble oil (especially of 10-5000 mPa.s viscosity), a water-soluble lubricant, an oil or grease without ethylenically unsaturated groups or an oil containing unsaturated fatty acids such as edible oil.

Abstract: In a process for filling and emptying a storage tank with aqueous dispersions, in which the tank is emptied through a pipe near the bottom, the outlet of the filling pipe follows the changes in the level of the liquid surface during filling and emptying and is adjusted so that it is at about the same height as the surface of the liquid. Also claimed is equipment for carrying out this process.

Abstract: Aqueous solutions of adhesive materials which can be easily filtered and deodorized, particularly for self-adhesive labels, with a solids content of over 65 % can be produced with good reproducibility of characteristics through copolymerization of esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm inhibitor and preferably in the presence of 0.01 to 5 % by weight of reducing agents, according to a special emulsion process. The highly concentrated and steam-deodorized adhesive material dispersion is free of coagulants and specks.
