Abstract: A guest digital device joins a playback session hosted by a host digital device and synchronizes playback of digital media content with playback on the host digital device. This enables multiple users to listen to or view media at the same time on their respective devices. A time-based synchronization process may be used to initially synchronize playback of the guest digital device to the host digital device. If synchronization is lost, the device may record and analyze audio during playback and a fingerprint-based synchronization approach may be applied that detects a time offset between fingerprints in the analyzed audio. If synchronization is still not achieved, a watermark-based synchronization approach may be applied in which watermarks are actively injected into the audio and the time offsets between the watermarks is detected.

Abstract: A tool for tuning the pitch of blades on a model propeller with pivoting blades, the tool comprising a mount for the model propeller and a calculation module. The mount allows the propeller to be positioned such that the axis of the propeller coincides with a fixed reference axis of the mount and to place each blade of the propeller, successively, in a measurement position. The calculation module determines the angle between a chord of a blade in the measurement position and a fixed reference plane of the tool, the fixed reference plane being orthogonal to the fixed reference axis, based on optical sightings by the calculation model on a suction face of the blade in the measurement position.

Abstract: A device for adjusting the pitch angle of propeller blades for a model engine including at least one rotor, the blades extending radially on the surface of the rotor to form a propeller. It includes a tool-holder including a base designed to be fixed to a part of the outside of the engine housing and an upper part, the aforementioned upper part being fitted with means of support movable horizontally along a longitudinal axis (XX?), the aforementioned axis being parallel to the main axis of the model engine, contactless means of optical measurement, the aforementioned means of measurement being mounted on the movable means of support by using means of travel in rotation around an axis of rotation, the aforementioned axis of rotation being the blade's axis of rotation.

Abstract: The present invention relates to a novel NaCl salt substitute agent free of aromatic flour and comprising at least one 5?-nucleotide yeast extract, preferably containing at least 1% of 5?-nucleotides relative to the solids content of the yeast extract, and a mixture of low-sodium potassium and ammonium salts, and to the use thereof as a salting agent. It also relates to the use of 5?-nucleotide yeast extract, preferably containing at least 1% of 5?-nucleotides relative to the solids content of the yeast extract, for the off-flavour masking effects thereof and/or for enhancing the salty taste and/or for reducing the amount of low-sodium potassium and/or ammonium salts.

Abstract: The invention relates to a tool for tuning the pitch of the blades of a model propeller (50) with pivoting blades, characterized in that it comprises: means (2, 13-16) for mounting the model propeller in the tool, able to make it possible to position the propeller in such a way that its axis of rotation coincides with a fixed reference axis (3) of the tool, and to place each blade of the propeller successively in a measurement position, optical means (4, 8-11) for determining the angle between a chord of a blade (51) in measurement position and a fixed reference plane of the tool orthogonal to the reference axis on the basis of two points (5, 6), referred to as measurement points, sighted by the said optical means on the suction face of the said blade in measurement position. The invention extends to a tool set additionally comprising at least one standard propeller provided with fixed blades of different pitches, and to a tuning method using the tool or the tool set according to the invention.

Abstract: Alumina agglomerates having controlled porosity and excellent mechanical properties, well suited as catalyst supports and adsorbents, are produced by (a) agglomerating an alumina powder prepared by rapidly dehydrating an aluminum hydroxide, (b) aging the agglomerates thus formed in an atmosphere of controlled humidity, (c) impregnating such aged agglomerates with a solution of at least one acid, (d) hydrothermally treating the thus impregnated agglomerates in a confined enclosure, and then (e) drying and calcining the agglomerates thus treated.

C., are produced by establishing a batch of starting material active alumina agglomerates in a confining and protective treatment zone, such starting agglomerates having been impregnated with water or an aqueous acid solution and the confining treatment zone itself being enclosed within an autoclaving assembly as to provide an interspace between the internal wall surfaces of the autoclaving assembly and the exterior wall surfaces of the treatment zone, and hydrothermally treating such impregnated agglomerates at a temperature of at least 80.degree. C. by directing a stream of a hot heat transfer fluid against the exterior wall surfaces of the treatment zone.

Abstract: Alumina, silica or silica-alumina containing catalysts are manufactured by incorporating at least one active element selected from the metals of the groups V, VI and VIII or their compounds to a carrier, and then drying and activating. The carrier or the catalyst is shaped into extrudates and the latter are crushed to coarse particles.
