Abstract: Disclosed are pressure vessels, especially an aerosol container, which comprise an interior that is subdivided into a storage chamber (3) and a propellant chamber (4) and are operated by means of a two-phase propellant. The gas phase (5) of the propellant encompasses carbon dioxide while the liquid phase (6) encompasses polyethylene glycol and/or a (C1-C4) monoether and/or a (C1-C4) diether of a polyethylene glycol, and carbon dioxide that is dissolved therein.

Abstract: A spray device for dispensing a cooling fluid comprises a reservoir in which the cooling fluid is stored in liquid form at an overpressure, a fluid outlet valve, and a spray head (3b) which has a capillary tube (30b). The capillary tube (30b) is arranged in a valve tappet (31b) in such a way that the inlet end of the capillary tube (30b) is connected to the fluid outlet valve of the reservoir and causes the cooling fluid to pass into the capillary tube (30b) when the fluid outlet valve is actuated. In the reservoir, there is a further capillary tube whose inlet end extends into the cooling fluid stored in the reservoir, and whose outlet end is connected to the fluid outlet valve.

Abstract: A slide-fastener stringer is pulled through a gapping station by a motor operatively engaging the stringer without slip and at least one feed roller engaging the stringer upstream of the gapping station. A storage unit downstream of the feed roller and upstream of the gapping station loops the stringer upstream of the station in a variable-size loop and has a rotatable and movable buffer roller over which the stringer passes and a pair of rotatable but nonmoving buffer rollers flanking the movable buffer roller. The movable roller is urged away from the flanking rollers with a force sufficient to tension the stringer. The drive of the feed roller is operated in accordance with the position of the movable buffer roller for stretching the stringer between the buffer rollers by at most 1%. A gapper at the station periodically clamps and longitudinally arrests the stringer and then cuts the coupling elements therefrom at the station.

Abstract: An apparatus for packing slide fasteners as they arrive in a longitudinal transport direction one after the other at a predetermined travel speed from a production facility has a speedup conveyor receiving the arriving slide fasteners and operating at a speed substantially higher than the travel speed thereof and a separating conveyor running transversely of the speedup conveyor and having an upstream end receiving the fasteners from the speedup conveyor and a downstream end transversely offset therefrom. A collection trough having a floor inclined to the horizontal, upper and lower ends, and a plate blocking the lower end is positioned underneath the separating conveyor to receive the fasteners therefrom and a downstream trough is aligned longitudinally with and has an upstream end separated by a space from the collection trough, a floor formed with a throughgoing aperture, and a downstream end. A collection vessel is provided underneath the downstream end of the downstream trough.

Abstract: A method of mounting a slider on a workpiece consisting of a pair of parallel and longitudinally extending tapes having confronting edges provided with interleavable coupling elements and formed by removal of sections of the elements to form longitudinally spaced gaps comprises the steps of first feeding the workpiece in a normally forward travel direction along a Z-shaped path having an upstream portion, a middle portion, and a downstream portion. Then the presence of one of the gaps is detected at the middle portion and, when such presence is detected, the workpiece is arrested at the middle portion. The one gap of the arrested workpiece is then spread and thereafter a slider is pushed transversely into the spread gap. The workpiece is then gripped in the upstream portion and pulled backward so as to pull the coupling elements through the slider pushed into the gap. Finally the slider is released to continue forward advance of the workpiece.

Abstract: A slide fastener is made from a workpiece formed of a pair of longitudinally extending parallel tapes having confronting edges provided with longitudinally extending and transversely couplable coupling elements. This workpiece is passed along a treatment path through a gapping station, a bottom-stop installing station, a slider-mounting station, a top-stop installing station, and a cutting station. The elements are removed from the tapes at gaps spaced longitudinally of the workpiece in the gapping station and a bottom stop is fitted to the elements at one end of each of the gaps in the bottom-stop installing station. A slider is mounted on the elements at the slider-mounting station between each gap and the following gap and a top stop is fitted to the elements in the top-stop installing station at each gap. Finally the tapes of the workpiece are transversely cut at the gaps at the cutting station into individual slide fasteners.
