Abstract:
The invention pertains to the textile livening agent with the antistatic effect and favorable dermatologic properties which contains softening, stabilizing, whitening, coloring, scenting and dermatologic components, anionactive, nonionogenic and cationactive tensides and other additives and 2-50 (preferably 4-25) wt. % of 3-(hydroxyalkylamino)-2-hydroxypropyl esters of fatty acids of the general formula RCOOCH.sub.2 CH(OH)CH.sub.2 N(R.sub.1 R.sub.2), where R are the C.sub.16 -C.sub.22 alkyls or alkenyls, R.sub.1 is H, CH.sub.2 CH.sub.2 OH, CH.sub.2 CH.sub.2 CH.sub.2 OH, CH.sub.3 CHCH.sub.2 OH, CH.sub.2 CH(OH)CH.sub.3, CH.sub.3 CH.sub.2 CHCH.sub.2 OH, CH.sub.3 CHCH.sub.2 CH.sub.2 OH, CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 OH, or CH.sub.3 CHCH(OH)CH.sub.3, and R.sub.2 is the same substituent as R.sub.1 except for H. The agent serves for the repeated regeneration of antistatic and other properties of fabrics made of synthetic fibers and is applied to washed and rinsed fabrics by a short-termed soaking, moderate squeeze and drying. The surface electric resistivity of the fabrics is effectively reduced even at the low humidity of environment already by a very small amount of the agent. The said agent is not toxic and its effect is not reduced even by certain amounts of anion-active detergents retained by fabric after incomplete rinsing.
Abstract:
Double-acting mechanical liquid spraying device having a housing which is adapted to be mounted upon and sealed to the neck of a liquid container, and which has a liquid-containing compartment therein. In the housing, aligned with the liquid-containing compartment, there is an operation cylinder which has an annular valve seat disposed transversely to and intermediate the length of such cylinder. Disposed within the liquid-containing compartment is a liquid pumping plunger of the cuff type which cooperates with the valve seat to close the opening through such seat when the plunger is in its forward terminal position, and which is driven to reciprocate within the liquid-containing compartment in forward and reverse liquid dispensing strokes. In each of such strokes the plunger forwards liquid from the liquid-containing compartment to a spray nozzle through a liquid-conducting passage. Interposed in the liquid-conducting passage between the plunger and the spray nozzle are a relief valve and a relief passage which bleed liquid back to the liquid container and allow atmospheric air to be drawn in through the spray nozzle at the end of the reverse stroke of the plunger, thereby to clear the spray nozzle of liquid at the end of each pumping cycle consisting of a forward and a reverse stroke. As a consequence, fast-drying liquids can be sprayed with the device of the invention.
Abstract:
Liquid atomizer having a reciprocable pump. The atomizer provides a reliable sealing of the piston rod of the pump with lowered requirements as to the manufacturing tolerances of parts, a simplified manner of venting, and the sealing of the atomizer against leakage when the atomizer is placed in any arbitrary rest position. A sleeve having a smaller inner diameter than the cylinder is mounted on the upper part of the cylinder of the pump and its upper part is in contact with the inner part of a neck of a housing for the atomizer. A free space between the inner wall of the housing and the outer wall of the cylinder of the pump is connected below with the interior of the bottle on which the atomizer is mounted, and the upper part of the free space communicates with the surface of a tube by radial channels passing through the sleeve of the cylinder. The tube slidingly passes through the neck of the housing, is connected on the top with an operating button, and ends below with a sealing cuff piston which covers, when in its upper position, the radial channels and, at the same time, bears by its upper part on the neck of the housing. The tube forms a part of a narrow upper part of a piston rod which reciprocates through the sleeve, whereas the lower broadened part of the piston rod bears the piston of the pump and a one-way valve.
