Abstract: After a reducing agent is added to a water reaction system containing silver ions to deposit silver particles by reduction, the silver particles are dried to obtain a silver powder which is heat-treated at a temperature of higher than 100° C. and lower than 400° C. The silver powder thus heat-treated has a maximum coefficient of thermal expansion of not greater than 1.5% at a temperature of 50° C. to 800° C., and has no heating peak when the silver powder is heated from 50° C. to 800° C. The silver powder has an ignition loss of not greater than 1.0% when the silver powder is ignited until the weight of the silver powder is constant at 800° C. The silver powder has a tap density of not less than 2 g/cm3 and a BET specific surface area of not greater than 5 m2/g.

Abstract: Centering device 14 of a bill validator comprises a pair of pinch jaws 15 positioned on the opposite sides of a passageway 6, and a centering motor 30 for moving pinch jaws 15 toward and away from each other for reciprocation of pinch jaws 15 so that pinch jaws 15 come into contact with side edges of a bill between pinch jaws 15 to align a central line of bill with a central line of passageway 6. As centering motor 30 stalls when warpage resistance by centered bill is greater than inherent holding torque of centering motor 30, centering device 14 has the simplified structure with reduced number of structural components for light weight and reliable centering operation.
Abstract: A method for optimally operating mechanically loaded, moved, particularly rotating components, such as gearboxes, wherein in the operating stage damage accumulation is used to evaluate the influence of a collective load on the lifespan of the loaded rotating components, the moving components (1) being divided into a plurality of segments (5-10) for determining individual collective loads (6; 18).
Abstract: A lice comb (10) including a plurality of teeth (14) for capturing lice when the teeth (14) are passed through hair. The lice comb (10) is provided with a receptacle (22) including an adhesive inner surface and a means for moving lice captured by the teeth (14) into the receptacle (22) such that the lice come into contact with the adhesive surface, preventing escape of the lice.

Abstract: Various embodiments of the invention provide a screw compressor for compressing a refrigerant in a refrigeration system. The screw compressor includes a rotor case, which accommodates a primary helical rotor that is intermeshed with at least one secondary helical rotor, to compress the refrigerant in the rotor case. The rotor case also includes a slide valve supporting member that is fixed on an inner wall of the rotor case. Moreover, a slide valve, located in the rotor case, slides axially on the slide valve supporting member. The slide valve controls the volume of refrigerant during compression. The slide valve is fitted with at least one internal pressure relief valve, to relieve internal pressure in the screw compressor.
Abstract: A cement additive, comprising nanostructured or not particles of SiO2—CaO—Al2O3 and at least one additive selected from the group consisting of nano-sized particles of SiO2, 2CaO.SiO2, 3CaO.SiO2, Al2O3, P—Ca and/or combinations thereof.
Abstract: A bottle carrier has a resilient ring dimensioned to encircle a neck of the bottle in an installed condition. A brim is unitarily formed with and depends from the resilient ring and is dimensioned to fall in facing or contacting relation to a shoulder of the bottle.
Abstract: Compliant inserts for surgical instruments having improved traction are provided. The clamping surface of the inserts includes a plurality of short and densely arranged traction elements. The tractive force supplied by the traction elements approaches that of steel jawed clamps.

Abstract: A process for producing refractory metal alloy powders includes the steps of blending at least one powder with at least one solvent and at least one binder to form a slurry; forming a plurality of agglomerates from the slurry; screening the plurality of agglomerates; sintering the plurality of agglomerates; and melting said plurality of agglomerates to form a plurality of homogenous, densified powder particles.
Abstract: A method for determining optimal source impedance at the input of a device under testing (DUT) in a measurement bench, includes the steps of calibrating a source pull type bench as a measurement bench, adjusting a load impedance and continuous bias of the DUT, generating an electric power signal by the source and injected in the DUT, acquiring input impedances of the DUT and corresponding gain performances.
Abstract: A method is provided for the production of an active-breathing composite in the form of a web, consisting of a nonwoven made of synthetic material and a layer fully or mainly consisting of polyurethane for utilization as counter ceiling webs for roofs and as facade webs. PU or a mixture of materials with a high fraction of PU is heated to melting temperature and extruded on a nonwoven made of PP in order to form a diffusion-open coating of the PP nonwoven and then pressing the PP nonwoven in order to form an active-breathing composite.
Abstract: A holder comprising on the one hand a base designed for fixing on a culinary item, and comprises a use positioning member and a rotary shaft, and on the other hand a handle pivoting on the rotary shaft and a lock mounted in such a way that it can move between a locked position in which it engages with the use positioning member in such a way as to immobilize the handle and a release position in which it allows it to be rotated. The use positioning member is on the rotary shaft.
Abstract: A method for processing bast-fiber materials involving loosening a material, placing said material in an aqueous medium, hydrodynamically processing material successively in two modes: first, in a continuous mode by performing a hydrodynamic wave field action, and then in a pulsed mode by performing a shock-wave action, wherein the pressure amplitude of the positive wave phase in the continuous mode is less than the pressure amplitude of the positive wave phase in the pulsed mode, and removing the material from the aqueous medium. It is possible by the method to produce a high quality cottonine, the linear density of which is equal to or less than 0.3 Tex with the optimal energy consumption of the production process.
