Abstract: This device comprises a driving shaft, which is rotary on itself around a central axis and which is secured to a head for driving the tool into rotation around the axis, the tool being added onto the driving head in a removable way. The driving head includes a driving hub which is adapted so as to be engaged with a driven hub of the tool in order to transmit a rotary movement between them. The driving head is provided with locking centrifugal weights for the tool on the driving head, said centrifugal weights being moveable, under the effect of a centrifugal force resulting from the setting into rotation of the driving head by the driving shaft, between a rest position, in which the centrifugal weights do not interfere with the driven hub, and a position of use, in which a portion of each of the centrifugal weights is brought closer to the central axis and mechanically cooperates with the driven hub in order to maintain it engaged with the driving hub.

Abstract: A fin for a water sports board including leading and trailing edges, and a base extending therebetween along a longitudinal base axis. A fin axis extends generally perpendicular to the longitudinal base axis, both axes residing within a longitudinal plane. First and second opposed side faces are formed on generally opposed sides of the longitudinal plane. First and second insert pre-preg sheets formed of structural strands bonded by a resin material are disposed adjacent respective ones of the first and second side faces on generally opposed sides of the longitudinal plane. An injection molded resin material is disposed between the first and second insert pre-preg sheets. A core is positioned between the first and second insert pre-preg sheets and is of a density less than the injection molded resin material.

Abstract: An advantageous and effective process for obtaining carboxymethyl cellulose (CMC) from agro-industrial residues, comprising the steps of a) Preparing the raw material, wherein the raw material is washed, dried, grounded and washed again; b) a pumping step, wherein the product obtained from the step a) is reacted with sodium hydroxide; c) a synthesis step, wherein consists in grounding the pulp; adding a solution of isopropanol and distilled water under stirring at room temperature; adding NaOH aqueous solution up to the alkalization of the mixture; adding monochloroacetic acid in isopropanol; filtrating; suspending in methanol solution and neutralizing with acetic acid. The CMC obtained from the process can be employed in a several industrial processes.

Abstract: An insert for a water sports board, wherein the insert includes a pre-preg flange extending outwardly from an injection molded central housing to provide enhance structural properties of the insert, as well as enhanced intermediate bonding between the injection molded central housing and a surface polymer. The pre-preg flange further improves the strength to weight ratio when compared to conventional inserts.

Abstract: This jar includes a bottom wall, bearing rotary mechanical elements for processing foodstuffs. This jar also includes a side wall extending transversely from the bottom wall while delimiting with the latter a free space in which the rotary elements act on the foodstuffs to be processed, this side wall having, opposite the bottom wall, a free end for introducing the foodstuffs into the free space. In order to make the use of this jar simple and efficient, the free end of the side wall has a regular pentagonal profile.

Abstract: A cylindrical battery comprises a spiral electrode assembly having a positive electrode plate being provided with a porous nickel sintered substrate using a nickel coated steel plate as a conductive core substrate, and containing a positive electrode active material mainly including a nickel hydroxide, a negative electrode plate, and a separator, and the positive electrode plate and the negative electrode plate are wound into a spiral form interposing the separator therebetween, and the positive electrode plate has a positive core substrate tab portion in which the conductive core substrate is exposed without the porous nickel sintered substrate at one end portion in the height direction, and in in a finally wound end portion of the spiral electrode assembly, a corner tip portion of the positive core substrate tab portion is bent in a direction toward an axis of the spiral electrode assembly.

Abstract: A display device is provided which may be used to display surfboard fins and related product literature. In one example, a display device includes a plurality of tubes and machined parts which may be assembled and configured as further disclosed herein. Such a display device may be used, for example, to hold and secure surfboard fins to facilitate display of the fins and permit the handling of the fins by consumers. Advantageously, the display device may also be implemented to prevent the fins from being completely detached from the display device without the use of an appropriate security device. The display device may also be implemented to hold and secure information (e.g., product literature) associated with the fins.

Abstract: The invention relates to a pharmaceutical composition of unit dose for inhalation by a human subject comprising a topical corticoid and a quinolone or fucidic acid, characterized in that the ratio of the weight of the topical corticoid to the weight of the quinolone or fucidic acid is between 0.02 and 20 and the amount of quinolone or of fucidic acid is less than 1 mg. This composition can be administered by nasal spray and is used for treating the upper and lower respiratory tract, in particular sinusitis and nasal polyps.

Abstract: The presently disclosed subject matter has application in the fields of Medicine, Neurology, Stomatology, Dentistry, Maxillofacial Surgery and Gerontology, using electronics nanotechnology and biomechanics technologies. The disclosed subject matter includes a bionic device of transduction of the mastication pressure into an electrical stimulus, capable of being perceived by the organism in the form of a nociceptive stimulus, which triggers in the organism an appropriate motor response of defense or decrease of muscle contraction. A generating device of nociceptive stimulus able to stimulate the brain areas related to chewing can be provided, modulating the muscular response thus avoiding the problems of overload during the process of mastication or while sleeping, involuntary movements called parafunctions of mastication, which translates to sharply wear down the dental crowns, also called bruxism.

Abstract: A method of measuring the in-situ Total Gas content of an unconventional reservoir rock, the method including: drilling a borehole through a measurement interval in the reservoir to generate an annular volume of drilling mud that includes cuttings and gas, the annular volume having a leading edge and a trailing edge; diverting the leading edge of the annular volume such that all of the annular volume is captured in a degassing storage system without being exposed to atmosphere; discontinuing the diversion of the annular volume when the trailing edge of the annular volume has been captured in the degassing storage system; measuring the gas volume in the degassing storage system to determine the amount of gas per annular volume; and calculating the in-situ Total Gas content of the reservoir with reference to the amount of gas and cuttings per annular volume.
