Title: Aqueous biocidal cationic dispersions of polymers and  their use as fungicidal, bactericidal and algicidal treatment agents
Inventor: HUTH HANS-ULLRICH
IPC: C09D5/14
Filed: 1988-04-06
Granted: 1994-08-30
Abstract: ABSTRACT OF THE DISCLOSURE:            Use of fine-particled biocidal aqueous cationic disper-sions of polymers as biocidal treatment agents for sub-strates at risk from microbes, preferably for fungicidal, bactericidal and/or algicidal treatments.  The disper-sions of polymers used are biocidal cationic dispersions of polymers which can be obtained from suitable monomers by emulsion polymerization and which contain biocidal cationically surfactant quaternary organic ammonium com-pounds, preferably tetra-substituted ammonium compounds of the formula (I) and/or alkyl- or alkenylpyridinium compounds of the formula (II), in particular in an amount of 0.1 to 20% by weight, based on the disperse polymer. The average particle diameter of the polymer particles in the biocidal cationic dispersions of polymers is preferably 0.02 to 0.5 µm at a cationic activity of 1.5 to 600 µmol per g of solid, measured at pH 7, and the solids content of the dispersions is preferably 3 to 40% by weight.  The biocidal cationic dispersions are prefer-ably used as treatment agents for the preservation of wood, for emulsion paint films and for polymer plasters or synthetic resin plasters, it being possible for the biocidal treatments which can be achieved to display surprising long-term biological actions.

Abstract: PR?CIS Un matériau en feuille pour réaliser un traitement cutané ou capillaire est décrit. Ce matériau est constitué par un filet emprisonnant un gel hydratable en couche mince dans ses mailles. Le gel est utilisé pour ses propriétés d'absorption de l'eau apportée par une humidification de la surface de la peau; il se réhydrate au moins partiellement en venant épouser, avec le filet retrouvant sa flexibilité naturelle, les aspérités du corps; puis il sèche sous l'influence de la température normale de la peau, la forme sèche étant reprise alors qu'il adhère toujours sur la peau. Du fait que le gel est prisonnier dans son filet, on peut alors retirer celui-ci d'un seul tenant, un traitement de désincrustation de la peau ayant été effectué par ledit gel. Un procédé de fabrication de ce matériau est également décrit.

Abstract: The performance of a treating agent added to a body of water employed in a cooling tower is continuously monitored by real-time analysis of a spectral or chemical characteristic of an inert tracer proportioned to the treating agent, said characteristic being indicative of tracer concentration, and converted to a voltage analog.  The voltage analog is compared to a monitor value representing par performance and if performance is nonstandard (nonpar) a signal is generated which alters the output of a pump which feeds the dosage of treating agent containing proportioned tracer.

Abstract: 1450427 Spring door closers with fluid damping G K N-STENMAN AB 12 Dec 1973 [21 Dec 1972] 57685/73 Heading E2M [Also in Division F2] A spring door closer, of the type in which door shaft 4 provided with a pinion 3 drives a piston 6 within a fluid filled cylinder 5 against a closer spring 9 and a fluid channel 11 links both sides of the piston, is provided with means located in the channel which constricts fluid flow during an initial section of the door closing movement but which widens this constriction during the final portion of the door opening movement. As shown an adjustable valve spindle 13 has a conical end portion 13a which engages in a seat 14a in a slidable sleeve 14 biassed toward the spindle by a spring 16. When the door is opened the piston moves to the left from the door closed position shown in Fig. 1 expelling fluid firstly via channels 11c, lid then, as the piston covers lid, through 11c alone. In this final stage the fluid forces sleeve 14 to the right to widen the constriction between 13a and 14a (Fig. 4). For the first portion of the closing movement i.e. before the piston uncovers channel 11d fluid is drawn into the cylinder through channel 11c forcing the sleeve 14 to the left to narrow this constriction. The slow movement of fluid through this narrowed constriction delays the closing of the door until channel lid is uncovered and provides an alternative passage for the fluid. Final damping of the door occurs as the piston covers exit passage 11a and fluid must flow through a passage 11b regulated by screw 12. A plate 24 resting against a washer 23 provides a safety valve to relieve pressure should the door be closed too quickly, though this may be replaced by a ball valve (Figs. 5-8 not shown). Fig. 9 shows a modification of the constriction means in which the spring 16 acts on a check valve 25 which seats into the sleeve 14 and has a slot 27 for the restricted passage of fluid in its closed position. This check valve provides overload protection during the opening of the door, enabling a larger fluid flow to pass.
