A capstan based system for pulling and accumulating the pull-cords used to lift hanging window coverings from their bottoms. A cylindrical capstan is supported in bearings so that it is free to rotate and move axially. A splined connection to a holding device permits controlled rotation and locking of the capstan. Each of one or more cords is attached to the capstan by means of a clip which can be...

The method comprises the steps of forming a sheet of powder suspended in a gas and moving toward the substrate to be coated, homogenizing the mixture of powder and gas by creating turbulences in it, surrounding the sheet with flowing gas having the same velocit...

1. A film, in particular for separating liquid or gaseous multicomponent systems, which is comprised of a sheet-like semipermeable membrane applied to a support layer which is smooth on both sides and permeable to media capable of flow, wherein the surface of the film which faces away from the smooth support layer has profiling generated by profile-imparting elements which are comprised of threads...

A small radius conveyor belt for traveling along both straight and laterally curved paths and a conveyor system including such belt is shown. A plurality of rods extend across the belt and are pivotally connected together by tractive central links and inner and outer edge links which are longitudinally expandable and collapsible. The inner links are fully expanded and the outer links are collapsed...

An aerosol spray dispenser system for use with a container having both product and propellant under pressure and in vapor and liquid phases, including a valve unit in which there are separate product and propellant passages, preferably valved by a single gasket, leading from the container to an impact mixing chamber disposed within the valve unit. Here streams of liquid and propellant impact one a...

The protection screen for sprayers, consisting of a rigid sheet of synthetic material, comprises a transversally curved plate (2) and a securing ring (3) which may be resiliently secured to the sprayer (4). The protection screen (1) is provided with a peripheral reinforcement wall (8) extending downwardly. The screen (1) is used to limit downwardly the spray flow delivered by the sprayer, for exam...

PURPOSE:To obtain a high quality recorded picture of stabilized density by controlling constantly at a uniform level the luminance of a fluophor in a dot array fluorescent tube. CONSTITUTION:A dot array fluorescent tube 200 has a surplus region Y in addition to a region X for photo information writing in which the fluophors for photo information writing are arranged and in the region Y surplus flu...

An extract component is separated from a raffinate component contained in a feed mixture by a process in which a unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates. A component concentration distribution is established within the system of units and divided into specific zones. Feed and displacement fluid are p...

Silica- or alumina-containing granules are loaded into a mold of which the inner walls at least are formed of a nonbonding material constituted of ferrochromite, magnesiochromite, calciochromite, or trivalent-chromium oxide. The mass is then heated to a temperature above the softening point of the granules so as to fuse them together and thereafter the heated mass is hardened. As the mass can inhe...

A variable reluctance motor fed by D.C. pulses is controlled by a rotation sensor. The motor has at least two phases. The stator is designed as a continuous magnetic circuit with two stator poles per phase. The stator poles for the different phases are arranged in sequence along the periphery of the rotor so that each pole adjoins poles pertaining to another phase, and such that diametrically oppo...
