Abstract: Apparatus to prevent fuel spillage from a fuel tank vent is provided for use in combination with a boat mounted fuel tank having a filler tube leading thereto from a fuel filler fitting mounted to a surface of the boat and a vent line leading from the fuel tank to a vent extending through the hull of the boat. A member having a hollow interior which may be generally cup shaped and has a removable cover member is mounted substantially flush with a surface of the boat, and in close proximity to the fuel filler fitting. The member has a fitting in the interior thereof which is connected to a first section of vent tube leading from the fuel tank. The interior of the member is also connected to a second section of vent tube that leads to the vent extending through the hull of the boat. When the cover member is on , the interior of the fuel tank is in communication with the vent. When the boat is to be refueled, the cover member is removed and a fuel collection container having a line with a second fitting complimentary to the first mentioned fitting is connected to the first mentioned fitting. Then the interior of the fuel tank is in communication with the container and any fuel overflow from the first section of vent tubing is collected in the container. When fueling is complete, the collection container fitting is removed from the first mentioned fitting and the cap is replaced on the member. The interior of the fuel tank is then in communication, through the first and second sections of vent tubing, with the hull-mounted vent.

Granted: 2007-03-27
Abstract: The invention relates to a method for reducing odour emissions of aqueous aromatic vinyl-1,3-diene-copolymer dispersions which have been stabilised with a protective colloid. The invention also relates to redispersion powders obtained by drying said dispersions. This is achieved by emulsion polymerisation of a mixture containing at least one aromatic vinyl and at least one 1,3-diene in the presence of one or more protective colloids and by optionally drying the polymer dispersion obtained thereby. The invention is characterised in that 0.01 to 15.0 wt. % of one or more monomers selected from the group of branched or unbranched alkyl esters containing 1 to 8 carbon atoms in the alkyl radical of monounsaturated mono- or dicarboxylic acids are added at the end of the polymerisation when the total content of the aqueous polymer dispersion containing free monomers ranges from > 0 to <= 20 wt. %, whereby the given wt. % refers to the polymer content of the dispersion.

Abstract: L'invention concerne un système de surveillance d'anodes permettant de surveiller l'intégrité d'anodes (2) situées sur une structure métallique telle qu'un système de chevauchement (1). Un circuit de signalisation (Sn) comportant le système de chevauchement (1) et une des anodes (2) est monté et des signaux appropriés sont recherchés par une station centrale (4). La réception du signal par la station centrale (4) dépend de l'intégrité de l'anode (2) en cours d'inspection à ce moment. Si l'anode (2) fait défaut ou est défectueuse, le signal attendu n'est pas reçu et, par conséquent, le défaut de l'anode (2) peut être détecté. Un filtre coupe-bande (5) est introduit en série entre chaque anode (2) et le système de chevauchement (1). Le filtre (5) fournit une impédance élevée qui peut être signalée dans le système de protection cathodique mais ne brouille pas celui-ci.

Title: Amplifier stabilisation
Inventor: RYDIN ARNE
IPC: H03F1/32
Filed: 2000-10-26
Granted: 2011-10-18
Abstract: The present invention relates generally to the problem of linearisation in electronic amplifiers, and more particularly to the problem of controlling phase shift in these systems. The invention measures the outgoing phase difference, directly or indirectly, and then rotates the Cartesian system accordingly to adjust the phase error in the system to within a few degrees.  The phase difference can be measured in different places in the system as can the performance of the Cartesian rotation. The rotation is necessary to make the system unconditionally stable independent of the phase difference between the main amplifier path and the reference path. The invention achieves stabilisation of the phase in a power amplifier, thereby eliminating the need for time-consuming adjustments and also allows the achievement of higher bandwidths since the phase control is very accurate.

Abstract: A circuit (100-1100) comprising a primary section and a multiple voltage secondary section. The multiple voltage secondary section includes a multiple voltage resonance section (x20), a filter section (x140, x44), and a load coupling section (x42). The circuit (100-1100) also includes a transformer, which is operatively configured to couple the primary and secondary sections.  The multiple voltage resonance section (x20) includes a capacitance (x28, x30), i.e., an Alexander Topology. This capacitance (x28, x30), which is preferable based on series capacitors (x28, x30), operatively generates a predetermined voltage, such that a turns ratio (N) of the transformer (x16) is lower than a non-multiple voltage resonance section to generate the predetermined voltage. Hence, this configuration decreases energy loss from the transformer (x16), thereby increasing efficiency.
