Abstract: The absorption device includes a hydrophilic powder and a casing which is permeable to a liquid, the casing being composed of an upper layer which is superimposed on a lower layer, the lower and upper layers being connected to each other by strong connections which delimit a confinement zone for the hydrophilic powder in the casing. Advantageously, the lower and upper layers are connected to each other by first weak connections. The first weak connections delimit a plurality of adjacent cells in the confinement zone, each cell enclosing a quantity of hydrophilic powder sufficient to bring about the breakage of the first weak connections which delimit the cell when the hydrophilic powder absorbs a liquid.

Abstract: The present disclosure relates to a magenta toner formulation that may be used in a toner printer cartridge for an electrophotographic printer. The magenta toner may include polymer resin binder containing three polymer resins with different number average molecular weight values. The concentration of such polymer resins may be selected to provide a desired temperature versus viscosity behavior for the magenta toner that may be configured to conform to the viscosity versus temperature provide for yellow, cyan and black toner.

Abstract: The present disclosure relates generally to chemically prepared toner (CPT) that employs a regulated cooling process subsequent to coalescence and fusing. The cooling process may influence the distribution of domain morphology of the components within a toner particle such as controlling release agent domain formation and accompanying migration to the toner particle surface.

Abstract: The present disclosure relates to a method of forming a toner composition, and to a toner composition, that has a controlled particle size distribution, wherein the particle size distribution may be controlled by adjusting the concentration of a charge control additive in a chemical process of toner manufacture. The toner may therefore have a controlled amount of toner particles having diameters of less than or equal to about 4.0 microns. The toner may therefore provide improved resistance to filming on a given printer component.

Abstract: A rotary sonotrode enabling welding to be carried out continuously over a large width. A sonotrode (S) more particularly of revolution, made of a first material for propagation of ultrasonic waves, more particularly metal, comprising a axial bar (2) and an active part (4) connected to the axial part (2), the bar extending uninterruptedly over the entire axial extent of the sonotrode, and a chamber (8), made of a second material which does not allow the transmission of ultrasonic waves from the first material to the second, the second material being more particularly air or avoid, is interposed between the bar (2) and the active part (4).

Abstract: A ruffling slide for making articles with stretchable portions includes a tubular sleeve for containing at least one resiliently elastic yarn element connecting the portions transversely provided on the sleeve and space apart in such a way that they define tubular ruffling sections. The connecting portions also form narrowed portions for locally clamping the elastic yarn elements. The yarn element inserts into the sleeve and is clamped at the narrowed portions in such a way that it extends freely through each tubular section and is movable therein between two positions, i.e., an inoperative position and an operative position in which said element is shorter than the section in question, whereby it may subsequently impart a ruffle thereto in a direction substantially perpendicular to the general direction of the sleeve.

Abstract: A welding and cutting counter head for joining and cutting sheeted materials comprising a welding counter-wheel rotatably supported on a shaft which is supported on a slide for movement towards and away from a location where the materials are joined, a cutting disk adjacent the counter-wheel and mounted for rotation with the counter-wheel, means for mounting the cutting disk for floating radial motion relative to the counter-wheel, and a resilient biasing means for biasing the cutting disk in a direction towards the materials joining location.
